Ethan and Adrian are reading the same book. At the beginning of the month, Ethan was on page 18 and Adrian was on page 45. Ethan will read 12 pages per day and Adrian will read 9 pages per day. Let E represent the page of the book that Ethan is on at the end of t days into the month, and let A represent the page of the book that Adrian is on at the end of t days into the month. Write an equation for each situation, in terms of t, and determine whether Ethan or Adrian is farther along in the book after 4 days.

Answers

Answer 1

The equations are e = 18+12t and a = 45+9t

Adrian will be father along in the book after 4 days. She will be 15 pages ahead of Ethan

Ethan's page number at the beginning of the month = 18

Adrian's page number at the beginning of the month = 45

Pages read by Ethan each day = 12 pages

Pages read by Adrian each day = 9 pages

Let e represent the page of the book that Ethan is on at the end of t days into the month. Let a represent the page of the book that Adrian is on at the end of t days into the month.

Formulating the equation we get the following:

e = 18 + 12t

a = 45 + 9t

Finding the page number of both Ethan and Adrian after 4 days by substituting the values in the equations we get:

e = 18+12(4)

e = 66

a = 45 + 9(4)

a = 81

To solve the inequality StartFraction m over negative 7 EndFraction less-than-or-equal-to 14, what should be done to both sides? I NEED TO GET THIS DONE NOW HELP IM SO CONFUSED

Answers

To solve the inequality given by -n/7 ≤ 14 , -7 should be multiplied to both sides of the inequality .

Any monotonically rising function can, by definition, be applied to both sides of an inequality without changing their connection to one another (provided that both expressions are in the domain of that function).

If a monotonically falling function were applied to both sides of an inequality, the inequality relation would be reversed.The rules for the additive inverse and the multiplicative inverse for positive numbers serve as illustrations of the use of a monotonically declining function.If the function is strictly monotonic and the inequality is strict (a b, a > b), the inequality remains strict.If only one of these conditions is fulfilled, the resulting inequality is not strict. The conditions for both additive and multiplicative inverses really serve as a demonstration that a strictly monotonically dropping function is being applied.

The inequality is -n/7 = 14

or, -n ≤ 14 × 7

or, -n ≤ 98

or, n ≥ -98

Therefore the first step is solve the inequality is to multiply both sides by 7.

Ahmed recorded a temperature drop of 2 degree F and a second temperature drop of 3 degree F. What is the total change in temperature?

Answers

Answer:

  a drop of 5 degree F, or -5 °F

Step-by-step explanation:

You want to know the total change in temperature after a drop of 2 degree F and a second temperature drop of 3 degree F.

Change

The total change will be the sum of changes.

We can figure the total drop in temperature as the sum of drops:

  2 °F +3 °F = 5 °F . . . . the total drop in temperature

If we use negative values to represent temperature drops, then the total change can be written as ...

  (-2 °F) +(-3 °F) = -5 °F . . . . . the total change in temperature

__

Additional comment

We often find it convenient to use negative numbers to represent decreases, drops, amounts below some reference level, and so on. Positive numbers can be used for the same purpose if we define the meaning of a positive number in the context.

Here, we can identify a temperature drop by saying it is a drop of 5 degrees, where a positive temperature drop means a change to a lower value. Or, we can say it is a change of -5 degrees, where a positive change is defined as a change to a higher value.

Defining the meaning of positive and negative numbers is especially important when an "improvement" is a reduction in some value (cost, for example). A positive improvement may mean a negative change, and vice versa.

Rectangle A is 5 in by 7 in. If the scale factor is 4, what is the area of the new rectangle B? How does it compare with the first rectangle?

Answers

The area of rectangle B is 560 square inches.

What is the area of rectangle?

Area of rectangle is the region occupied by a rectangle within its four sides or boundaries. The area of a rectangle depends on its sides. Basically, the formula for area is equal to the product of length and breadth of the rectangle.

Given that,

Scale factor = 4

Rectangle A has

length = 5 inches

breadth =  7 inches

Area of a rectangle A = length×breadth

                                    = 5×7

                                    = 35 square inches

Scale factor is 4 so length and width of a new rectangle is

length = 5×4 = 20 inches

breadth =  7×4 = 28 inches

Area of a rectangle B = length×breadth

                                    = 20×28

                                    = 560 square inches

Hence, The area of rectangle B is 560 square inches.

What is the value of X in the equation 1/5x - 2/3y = 30, when y = 15?

Answers

Answer:

x = 200

Step-by-step explanation:

a) Simplify both sides of the equation.

1/5x - 2/3(15) = 30

1/5x + -10 = 30

1/5x - 10 = 30

b) Add 10 to both sides.

1/5x - 10 + 10 = 30 + 10

1/5x = 40

c) Multiply both sides by 5.

5 * (1/5x) = (5) * (40)

x = 200

This problem can be evaluated in steps.

1. Plug 15 in for y

1/5x - 2/3y = 30

→ 1/5x - 2/3(15) = 30

→ 1/5x - 10 = 30

2. Add 10 to both sides

1/5x - 10 = 30

→ 1/5x = 40

3. Divide both sides by 1/5

1/5x = 40

→ x = 200

4. Plug in 200 for x to see if it’s correct

1/5(200) - 2/3(15) = 30

→ 40 - 10 = 30

Because this equation is true, we have found our answer.

The shape comprises a semicircle, rectangle, and a trapezoid

A) The shape below will illustrate how the side length of the rectangle will be calculated

Part I is the semicircle of diameter

[tex]\begin{gathered} d=8\operatorname{cm} \\ r=\frac{d}{2} \\ r=\frac{8}{2}=4\operatorname{cm} \end{gathered}[/tex]

From the diagram above

[tex]AB=r=4\operatorname{cm}[/tex]

To find the missing side length of the rectangle , we will use the relation below

[tex]AB+BC+CD=12\operatorname{cm}[/tex]

Where.

[tex]\begin{gathered} AB=4\operatorname{cm} \\ CD=3.5\operatorname{cm} \end{gathered}[/tex]

By substituting the values, we will have

[tex]\begin{gathered} AB+BC+CD=12\operatorname{cm} \\ 4+BC+3.5=12\operatorname{cm} \\ 7.5+BC=12\operatorname{cm} \\ BC=12-7.5 \\ BC=4.5cm \end{gathered}[/tex]

The missing side length of the rectangle is = 4.5 cm

Hence,

The rectangle can be represented below as

The formula for the area of the rectangle is

[tex]\begin{gathered} A_{\text{rectangle}}=\text{length}\times breadth \\ \text{where,} \\ \text{length}=8\operatorname{cm} \\ \text{breadth}=4.5\operatorname{cm} \end{gathered}[/tex]

Hence,

The Area of the rectangle = 36cm²

B) To calculate the area of the semicircle, we will use the formula below

[tex]\begin{gathered} A_{\text{semicircle}}=\frac{\pi\times r^2}{2} \\ \text{where,} \\ r=4\operatorname{cm} \end{gathered}[/tex]

By substituting the values , we will have

[tex]\begin{gathered} A_{\text{semicircle}}=\frac{\pi\times r^2}{2} \\ A_{\text{semicircle}}=\frac{\pi\times4^2}{2}=\frac{16\pi}{2}=8\pi \\ A_{\text{semicircle}}=25.13\operatorname{cm}^2 \end{gathered}[/tex]

Hence,

The area of the semicircle = 25.13 cm²

To calculate the area of the trapezoid, we will use the formula below

[tex]\begin{gathered} A_{\text{trapezoid}}=\frac{1}{2}(a+b)\times h \\ \text{where,} \\ a=8\operatorname{cm} \\ b=15\operatorname{cm} \\ h=3.5\operatorname{cm} \end{gathered}[/tex]

The diagram below represents the trapezoid

By substituting the values, we will have

[tex]\begin{gathered} A_{\text{trapezoid}}=\frac{1}{2}(a+b)\times h \\ A_{\text{trapezoid}}=\frac{1}{2}(8\operatorname{cm}+15\operatorname{cm})\times3.5\operatorname{cm} \\ A_{\text{trapezoid}}=\frac{1}{2}(23\operatorname{cm})\times3.5\operatorname{cm} \\ A_{\text{trapezoid}}=\frac{80.5\operatorname{cm}}{2} \\ A_{\text{trapezoid}}=40.25\operatorname{cm}^2 \end{gathered}[/tex]

the ratio of bots to girls in a school is nine : ten. what does this ratio mean. if there are 300 girls at the school, how many total students are at the school.

Answers

The number of the total students that are at the school is 570 if the ratio of boys to girls in a school is nine: ten and there are 300 girls at the school.

What is the ratio formula?

The ratio formula is given as a:b = a/b for any two quantities, let's say a and b.

Given that a and b are separate amounts for two quantities, the combined total quantity is denoted as (a + b).

How are these ratio difficulties solved?

Three steps are necessary to determine the ratio of three numbers:

Step 1: Add the ratio's numbers together to determine the total number of pieces.

Step 2: By dividing the given sum by the total number of parts, determine the value of each component in the ratio.

Step 3: Divide the original ratio by the sum of each component's values.

The ratio is given as 9:10 as boys to girls.

Number of girls = 300

Thus, girls will be 10x and boys will be 9x

then 10x = 300

⇒x = 30

Then we can calculate the number of boys as

9x = 9*30

=270

Thus, the total number of students in the school

= exact number of girls + exact number of boys

= 300 + 270

= 570

Given the function below, determine the following.

f(x)= 10x +8

Find f(5).

Find f(-7).

Find a if f(x) = 88.

Answers

Answer:

Solutions Below.

Step-by-step explanation:

These questions test on the concept of Functions Substitution.

Function Substitution

Function Substitution is about giving an input (domain) to a function to produce an output (range)

Example: f(x) = 9x , f(9) = 9(9) = 81

Application

We are given the following function:

f(x) = 10x + 8, where we can express it as

y = 10x + 8

Now we can find the value of f(5) by substituting x = 5 into the function. (Meaning: Find the value of y when x = 5.)

f(5) = y = 10(5) + 8 = 50 + 8 = 58

Next, applying the same concept, we can find the value of f(-7) by substituting x = - 7 into the function. (Meaning: Find the value of y when x = -7.)

f(-7) = y = 10(-7) + 8 = -70 + 8 = - 62

This last question requires us to work in reverse, where we find the value of x when f(x) = y = 88.

f(x) = y = 10x + 8

10x + 8 = 88

10x = 88 - 8

10x = 80

x = 80 ÷ 10 = 8

What are linear equation?

A x + B y = C represents a two-variable linear equation in its standard form. As an illustration, the conventional form of the linear equation 2x + 3y = 5 It is rather simple to locate both intercepts when an equation is stated in this way (x and y). An algebraic equation with simply a constant and a first-order (linear) term, such as y = mx +b, where m is the slope and b is the y-intercept, is known as a linear equation. The variables in the previous sentence, y and x, are referred to as a "linear equation with two variables" at times. Ax + b = 0, where a and b are two integers, and x is a variable, is an example of a linear equation with one variable. This equation has only one solution. 2x + 3 = 8, for instance.

According to the given points

x = -1

So

y = (-3/2)(-1) + 5

y = 6.5

how can i find the angle of elevation of the sun to nearest degree?

Answers

SOLUTION

From the diagram at the right of the question, a right-angle has been formed already. So we will use SOHCAHTOA to find angle A. Looking at angle A, the opposite side is 140 ft and the adjacent side is 173 ft.

Using TOA, we have

[tex]\begin{gathered} TOA,tanA=\frac{opposite}{adjacent} \\ tanA=\frac{140}{173} \\ tanA=0.80924855 \\ A=tan^{-1}0.80924855 \\ A=38.98146539 \end{gathered}[/tex]

Hence the answer is 39 degrees
