the mesures of two suplementary angles are (1/2x) and (x+30) betermine te value of x

Answers

Answer 1
Answer:

x = 100

Step-by-step Explanation:

Supplementary angles add up to 180 degrees, so we can set up the equation:

(1/2x) + (x + 30) = 180

To solve for x, we can start by simplifying the left side of the equation by combining the terms:

(1/2x) + x + 30 = 180

Multiplying both sides of the equation by 2 to eliminate the fraction:

1x + 2(x + 30) = 360

Simplifying the right side of the equation:

1x + 2x + 60 = 360

Combining like terms:

3x + 60 = 360

Subtracting 60 from both sides of the equation:

3x = 300

Dividing both sides of the equation by 3:

x = 100

Therefore, the value of x is 100.

Further explanation:

Supplementary angles are two angles whose sum is 180 degrees. Let's use this fact to form an equation with the given measures:

(1/2x) + (x+30) = 180

To solve for x, we need to isolate it on one side of the equation. Let's start by simplifying the left side:

1/2x + x + 30 = 180
3/2x + 30 = 180
3/2x = 150
x = 100

Therefore, the value of x is 100. To check this result, we can substitute x=100 into the original measures:

(1/2x) = 50
(x+30) = 130

And indeed, 50 and 130 are supplementary angles whose sum is 180.

What justifies inequality?

The idea of inequality, which is the state of not being equal, especially in terms of status, rights, and opportunities1, is at the core of social justice theories. However, because it frequently has diverse meanings to different people, it is prone to misunderstanding in public discourse.

Part A:

We can solve the inequality as follows:

1/4x - 3 - 5 > 4

1/4x - 8 > 4

1/4x > 12

x > 48

Therefore, the solution to the inequality is x > 48.

Part B:

Since the inequality is stringent, the graph of the solution would be a number line with an open circle at 48 and an arrow pointing to the right, signifying that all numbers greater than 48 are solutions to the inequality. The answer would be (48, ) in interval notation.

what is trapezium ?

A parallelogram with at least two pair of parallel sides is known as a trapezium in geometry (or a parallelogram in American English). The legs of a trapezium are the non-parallel sides, whereas the parallel sides are referred to as the bases. The legs of a zygomatic arch might be equal in length (isosceles) or varied in length (non-isosceles). By averaging the widths of the two bases and multiplying by the height, a trapezium's area can be determined (the perpendicular distance between the two bases). that is Area equals (a + b)*h / 2. where h is the trapezium's height and a and b are the lengths of the base's two parallel sides (the bases).

given

MN can be used in place of XV2 in the equation, and the result is simplified to:

XV² = (1/4) (WX + 18)² + h²

Now, we can add the following expression for XV2 to the equation for WX2:

WX² = 18² + XV²

WX² = 18² + (1/4) (WX + 18)² + h²

Adding and subtracting:

How does projectile motion work?

Any object that is fired into the air and travels in that direction is referred to as a projectile. Gravitation, however, is another force that an object experiences after the first force that pushes it.

Three distinct individuals, Alberto, Ben, and Carrie, each toss a ball straight up into the air.

Following equation may be used to explain Alberto's throw.

[tex]H = -16t^2 + 32t + 4[/tex]

Now , to find the maximum height, we solve for first derivative w.r.t.t,

[tex]-32t + 32 = 0[/tex]

[tex]32t=32\\t = 1s[/tex]

Using t=1, we can find maximum height as

[tex]H =-16(1)^2 + 32(1) + 4\\\\H=(-16)+32+4[/tex]

[tex]H= 20[/tex] ft

Thus, when Alberto threw ball, maximum height attained= 20 ft and total time duration ball was in air = 1s.

From the given table( refer to attached image),

Fom given table,

we can drive the function for maximum height as,

[tex]H=at^2+bt+c[/tex]

now, putting values of t, to get values of H,

solving equation 1 and 2,

a=(-4) and b=12

∴[tex]H=-4t^2+12t+6[/tex]

we know, [tex]t=\frac{-b}{2a}\\\\t=\frac{-12}{-8}=3/2=1.5s[/tex]

When Ben threw ball, the maximum height ball attained was 14 ft and total time duration for which ball was in air was 1.5 seconds.

A campground allows a maximum of 6 campers in a camp site. How many camp sites does a group of 237 campers need?

Answers

a group of 237 campers would require 40 campsites (since we cannot have half of a campsite).

How to solve the question?

To determine the number of camp sites required for a group of 237 campers, we can divide the total number of campers by the maximum number of campers allowed per site.

237 campers ÷ 6 campers per site = 39.5

Since we cannot have a fraction of a campsite, we need to round up to the nearest whole number. This is because we need to ensure that there is enough space for all of the campers, and rounding up will ensure that we have enough sites to accommodate them.

Therefore, a group of 237 campers would require 40 campsites (since we cannot have half of a campsite).

It is important to note that while this calculation is a good starting point, it is always a good idea to check with the campground to ensure that they can accommodate a group of this size. Additionally, the campground may have specific policies or procedures in place for reserving campsites for large groups.

Jack and Carlie each deposit $17,250 into accounts that earn 6% interest for 6.5 years. Jack's account earns annual simple interest and Carlie's account earns annual compound interest. Who will earn more interest after 6.5 years, and how much more interest will they earn?

Answers

Okay, let's calculate the interest earned by each person over 6.5 years.

Jack's account earns annual simple interest, so the formula for simple interest is:

I = P * r * t

where:
I = interest earned
P = principal (initial amount deposited)
r = annual interest rate
t = time in years

Using the given values, we get:

I = 17,250 * 0.06 * 6.5
I = $6,332.50

Therefore, Jack will earn $6,332.50 in simple interest over 6.5 years.

Carlie's account earns annual compound interest, so the formula for compound interest is:

A = P * (1 + r/n)^(n*t)

where:
A = amount after time t
P = principal (initial amount deposited)
r = annual interest rate
n = number of times interest is compounded per year
t = time in years

Using the given values, we get:

A = 17,250 * (1 + 0.06/1)^(1*6.5)
A = $27,943.93

The amount after 6.5 years is $27,943.93, which includes the principal and compound interest earned. To find the amount of interest earned, we subtract the principal:

Interest earned = A - P = $27,943.93 - $17,250 = $10,693.93

Therefore, Carlie will earn $10,693.93 in compound interest over 6.5 years.

So, Carlie will earn more interest than Jack, and the difference between the interest earned is:

$10,693.93 - $6,332.50 = $4,361.43

Therefore, Carlie will earn $4,361.43 more interest than Jack over 6.5 years.

Answers

To find the values of x for which (x2 − 4)(x + 3) = 0, we can use the zero product property which states that if the product of two factors is zero, then at least one of the factors must be zero. Therefore, we can set each factor equal to zero and solve for x:

(x2 − 4) = 0 or (x + 3) = 0

Solving for x in the first equation, we get:

x2 = 4 x = ±2

Solving for x in the second equation, we get:

x = −3

Therefore, the values of x for which (x2 − 4)(x + 3) = 0 are −2, 2, and −3. The answer choices that correspond to these values are R. −2, S. 2, and P. −3.

The quadrilateral's opposing sides are equal. Triangles ABC and ABCD have equal angles on either side of their equal sides. In the quadrilateral ACBD, the opposing angles are also equal. A parallelogram is formed by ACBD.

We can use the fact that the total of the angles of a triangle is always 180 degrees to determine the measure of angle CBD. As a result, we have:

Angle ABD + Angle CBD + Angle BCD = 180 degrees

Substituting the given angle measures, we get:

Angle ABD + Angle CBD + 90 degrees = 180 degrees

Simplifying, we get:

Angle ABD + Angle CBD = 90 degrees

But we know that Angle ABD = Angle CBD, so we can substitute:

2 x Angle ABD = 90 degrees

To save on shipping costs, Camile should choose a box that is lightweight and has a small volume.

Why should  Camile  choose a box that is lightweight and has a small volume?

This is because she has realized that she is charged based on the volume of the box and not the weight.

Therefore, a smaller volume box would cost her less than a larger volume box of the same weight.

For example, if Camile needs to ship a 5-pound item, she should choose a smaller box with a volume that is just enough to fit the item, rather than a larger box with more empty space. This is because the larger box would have a greater volume, and therefore, incur a higher shipping cost even though it weighs the same as the smaller box.

Which system of equations can be used to determine the values of x and y?

Answers

Kalani deposited $200 into her checking account every week and $400 into her savings account every month.

What is system of equation?

A group of equations that must be solved simultaneously is referred to as a system of equations. Typically, a system of equations involves multiple variables, and the goal is to find the values of those variables that satisfy all of the equations in the system.

According to question:

Let's start by using the given information to write equations for the total amount deposited in each account over the course of the year.

For the checking account, Kalani deposited x dollars every week for 52 weeks, so the total amount deposited for the year is:

52x

For the savings account, Kalani deposited y dollars every month for 12 months, so the total amount deposited for the year is:

12y

We are also told that each checking account deposit was half the amount of each savings account deposit, so we can write:

x = (1/2)y

Finally, we are given that the total of all deposits for the year was $15,200, so we can write:

52x + 12y = 15200

A system of two equations with two variables is now available:

x = (1/2)y

52x + 12y = 15200

We can solve this system to determine the values of x and y. The result of putting the first equation into the second equation is:

52(1/2)y + 12y = 15200

Simplifying:

26y + 12y = 15200

38y = 15200

y = 400

Substituting y = 400 into the first equation, we get:

x = (1/2)y = (1/2)(400) = 200

Therefore, Kalani deposited $200 into her checking account every week and $400 into her savings account every month.

To determine the range of surveyed students that agreed with the statement, we need to calculate the minimum and maximum percentages based on the margin of error. Given that 86% of students agreed with the statement and the margin of error is ±3.7%, we can find the range as follows:

Minimum percentage: 86% - 3.7% = 82.3%

Maximum percentage: 86% + 3.7% = 89.7%

Now, we'll apply these percentages to the total number of surveyed students (2,006):

Minimum number of students: 0.823 x 2,006 ≈ 1,650 students

Maximum number of students: 0.897 x 2,006 ≈ 1,800 students

Range of Surveyed Students: 1,650 to 1,800 students

b. To determine the range of grade 10-12 students in OCPS who would likely agree with the statement, we'll apply the same minimum and maximum percentages found earlier (82.3% and 89.7%) to the total number of grade 10-12 students in Orange County Public Schools (47,851):

Minimum number of students: 0.823 * 47,851 = 39,364 students

Maximum number of students: 0.897 * 47,851 = 42,972 students

Range of Students in Orange County: 39,364 to 42,972 students

The above answer is based on the information below provided in the picture;

A research survey of 2,006 public and private school students in the United States (grades 10-12) between April 12 and June 12, 2016 asked students if they agreed with the statement, "If I make a mistake, I try to figure out where I went wrong." The survey found that 86% students agreed with the statement. The margin of error for the survey is +3.7%.

Cylinder M and cylinder N are similar. The radius of cylinder N is equal to its height, and the ratio of the height of cylinder N to the height of cylinder M is 5: 3. The surface area of cylinder N is 256m square feet greater than the surface area of cylinder M. Find the surface area of each cylinder,

Answers

The surface area of cylinder M is approximately 184.85 square feet, and the surface area of cylinder N is approximately 401.92 square feet.

How do we find the surface area of both cylinders?

Let r_N and h_N be the radius and height of cylinder N, and r_M and h_M be the radius and height of cylinder M. We are given that the radius of cylinder N is equal to its height (rN = hN), and the ratio of the height of cylinder N to the height of cylinder M is 5 : 3.

So, we can write:

hN = rN

hN / hM = 5 / 3

The surface area formulas for cylinders M and N:

Surface Area (M) = 2πr_MhM + 2πr_M^2

Surface Area (N) = 2πrNhN + 2πrN^2

If Surface Area (N) = Surface Area (M) + 256

∴ 2πrNhN + 2πrN^2 = 2πrMhM + 2πrM^2 + 256

Combine like terms:

4πrN^2 = 2πrMhM + 2πrM^2 + 256

Divide both sides by 2π:

2rN^2 = rMhM + rM^2 + 128/π

Since hN = rN, we can write:

hM = (3/5)rN

Now substitute hM into equation

2rN^2 = rM((3/5)rN) + rM^2 + 128/π

2rN^2 = (3/5)rN x ((3/5)rN) + ((3/5)rN)^2 + 128/π

= 2rN^2 = (9/25)rN^2 + (9/25)rN^2 + 128/π

= 2rN^2 = (18/25)rN^2 + 128/π

rN = 5.64, hN = 5.64,

rM = 5.64 x (3/5) = 3.38

rM = 3.38.

let's calculate the surface areas:

Surface Area (M) = 2π(3.38)(3.38) + 2π(3.38)^2 ≈ 71.15 + 113.70 ≈ 184.85 square feet

Surface Area (N) = 2π(5.64)(5.64) + 2π(5.64)^2 ≈ 200.96 + 200.96 ≈ 401.92 square feet

Select and use the most direct method to solve 2x(x + 1.5) = -1.

Answers

2x^2+3x=−1

2x^2+3x+1=0

2x^2+2x+x+1=0

2x(x+1)+(x+1)=0

(x+1)(2x+1)=0

x=−1,− 1/2

The solutions to the equation 2x(x + 1.5) = -1 are x = -1/2 and x = -1.

What is an equation?

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

We can use the distributive property to simplify the left-hand side of the equation:

2x(x + 1.5) = -1

2x^2 + 3x = -1

Now we can move all the terms to one side of the equation:

2x² + 3x + 1 = 0

This is a quadratic equation in standard form, where a = 2, b = 3, and c = 1. We can use the quadratic formula to solve for x:

x = (-b ± √(b² - 4ac)) / 2a

Plugging in the values for a, b, and c, we get:

x = (-3 ± √(3² - 4(2)(1))) / 2(2)

Simplifying this expression, we get:

x = (-3 ± √(1)) / 4

x = (-3 ± 1) / 4

x = -1/2 or x = -1

Therefore,

The solutions to the equation 2x(x + 1.5) = -1 are x = -1/2 and x = -1.

Find the exact value of tan P in simplest radical form. √85 2 N √89​

Answers

Answer:

We can start by using the tangent formula:

tan(P) = sin(P) / cos(P)

We are not given the values of sin(P) and cos(P) directly, but we can use the Pythagorean identity to relate them:

sin^2(P) + cos^2(P) = 1

We can rearrange this expression to solve for sin(P) in terms of cos(P):

sin^2(P) = 1 - cos^2(P)

sin(P) = ±√(1 - cos^2(P))

Now we can substitute this expression into the tangent formula:

tan(P) = ±√(1 - cos^2(P)) / cos(P)

Substituting the given values and simplifying:

tan(P) = ±√(1 - (2/√85)^2) / (1/√89)

tan(P) = ±√(1 - 4/85) * √89

tan(P) = ±√(81/85) * √89 / 1

We want to express tan P in simplest radical form, so we can simplify the square root by factoring out the greatest perfect square factor of the numerator:

tan(P) = ±(√9/√85) * (√89/1)

tan(P) = ±(3/√85) * (√89/1)

Therefore, the exact value of tan P in simplest radical form is ±(3/√85) * (√89/1).

What is the measure of Arc A U? 44° 50° 64° 92°

Answers

The measure of Arc AU is 50⁰. Hence, the correct option is B.

An "arc" in mathematics is a straight line that connects two endpoints. An arc is typically one of a circle's parts. In essence, it is a portion of a circle's circumference. A curve contains an arc.

arc QU = 88 and <QUA = 111

QDA = 2 <QUA

= 2 X 111

= 222⁰

Now, QUA = 360- 222 = 138

arc AU = QUA - arc QU

= 138- 58

= 50⁰

Hence, the measure of AU is 50⁰.
