What is an isosceles triangle?

Any triangle with two equal sides and angles with equal measures on opposite sides is said to be an isosceles.

Based on the given diagram,

BD is perpendicular to AC because the given angle D is 90 degrees.

And, AD = DC (Given)

or, 4x = x + 9

or, 4x -x = 9

or, 3x = 9

or, x = 3

Then, AD = 4x = 4*3 = 12

And, AB = BC

So, the two sides of a given triangle are equal to each other.

Then, triangle ABC is an isosceles triangle.

Based on the above calculation and data, we can conclude that

Hence, Choices B, C and D are required answer choices.

Answer:

The number that twice the sum of it and negative seven is eight is 11.

Twice the sum of the number and negative seven is eight. The number can be found as follows:

let

the number  = x

According to the word expression, twice the value of  the addition of x and minus seven is equals to 8. Hence, we will find the value of x in the equation formed from the words expression.

The variable x is the required number.

Therefore,

2(x + (-7)) = 8

2(x - 7) = 8

open the brackets

2(x - 7) = 8

2x  - 14 = 8

add 14 to both sides of the equation

2x  - 14 = 8

2x  - 14 + 14 = 8 + 14

2x = 22

divide both sides by 2

x = 22 / 2

x = 11

The graph that could be used to determine the possible variance levels that would result in an acceptable height is the third graph.

Fron the information, the required model height for the designed clothes should be less than or equal to 5 feet 10 inches. In this case, the equation for the variance in height is of the straight line form;

y = m·x + c

Where x is the height  in inches

Given that the maximum height allowable is 70 inches, when x = 0 we have;

y = m·0 + c = 70

Therefore, c = 70

Also when the variance = 0 the maximum height should be 70 which gives the x and y-intercepts as 70 and 70 respectively such that m = 1

The equation becomes;

y ≤ x + 70

Also when x > 70, we have y ≤ -x + 70   with a slope of -1

In this case, to graph an inequality, we will need to shade the area of interest which in this case of ≤ is on the lower side of the solid line.

Answer:

y=2/3x-2

Step-by-step explanation:

The equation is y = mx + b and m is the slope. You were already given the slope and you were even given a point. All you have to do is graph the point and use the slope until it intercepts the y-axis.

1. Plot the point (9,-8)

2. Go up 2, left 3 spots until the line hits the y-axis (the vertical one)

3. That point is what b will be equal to in y = mx + b

OR you can convert a point-slope equation into slope intercept

1. The formula for point slope is y – y1 = m(x – x1)

2. Plug in the given numbers and it will look like this: y+8=2/3(x+8)

3. Do the math and get a solution of y=2/3x-2

Step-by-step explanation:

The expression 5x + 6y - 3x is equivalent to:

2x + 6y

This is because 5x and -3x can be combined by adding them together, which gives 2x.

The expression 5x + 6y - 3x is also equivalent to:

x + 6y - 3x

This is because 5x and -3x can be combined by adding them together, which gives x.

However, the expression 5x + 6y - 3x is not equivalent to:

2x - 3y

This is because the coefficient of the y term is 6, not -3.

The expression 5x + 6y - 3x is also not equivalent to:

x + y

This is because the coefficient of the y term is 6, not 1.

When Bobby takes out a mortgage for $30 years at 4% interest with $835.48 in monthly payments, the total principal loan amount is $255644.

In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100).

Here,

The interest paid per month=$835.48

Interest paid in 30 years=835.48*12*30

Rate of interest=4%=0.04

Time=30 years

Principal=I/RT

=(835.48*30*12)/(0.04*30)

=$250644

Using simple mathematical operations, we know that a-b can be -1, -2, and 0.

A mathematical "operation" is the process of calculating a value utilizing operands and a math operator.

The supplied operands or integers must adhere to a set of predefined rules that are connected to the symbol of the math operator.

Parentheses, Exponents, Multiplication, Division, and Addition Subtraction are also known as PEMDAS (from left to right).

So, we have: 2 < a < 5, 3 < b < 7

Now, a - b will be:

the values of a can be 3 and 4

Similarly, the value of b can be 4 and 5.

So there are 4 possibilities as shown:

3 - 4 = -1

3 - 5 = -2

4 - 4 = 0

4 - 5 = -1

785.4 cubic feet

Step 1: Start by calculating the area of the base of the storage tank. The area of a circle is calculated by: A = π*r², where r is the radius of the circle.

Step 2: For Emma’s cylindrical storage tank, the radius of the base is 5 feet. Substitute this value in the formula and calculate the area of the base, which is equal to: A = π*5² = 78.54 square feet.

Step 3: Now we need to calculate the volume of the cylindrical storage tank. The volume of a cylinder is calculated by: V = π*r²*h, where r is the radius of the circle and h is the height of the cylinder. For Emma’s tank, the height is 10 feet. Substitute these values in the formula and calculate the volume, which is equal to: V = π*5²*10 = 785.4 cubic feet.

Step 4: Therefore, Emma’s cylindrical storage tank has a capacity of 785.4 cubic feet.

The ball will rise 15 cm height on the right-hand incline when friction is discounted.

The force preventing sliding against one another of solid surfaces, fluid layers, and material components is known as friction.

Given that,

The height of the ball  = 15 cm

Since, the friction force is not counted here, this implies that there will be no friction force to stop the object.

The rise of the height on the right-hand incline will be same to the initial height.

Therefore, the ball will rise 15 cm height on the right-hand incline.

0.137606 the standard error of the average amount of coffee a stat 107 student drinks per day is greater than 12.7 oz.

Data dispersion in regard to the mean is quantified by a standard deviation, or "σ". Statisticians can assess if the data fits into a normal distribution or another mathematical connection using the standard deviation. The average, or mean, data point will be within one standard deviation of 68% of the data points if the data follow a normal curve.

Given that,

Standard deviation (σ) = 5.2 oz

mean (μ) = 10 oz

Number of students (n) = 120

As we know,

P ( z > 12.7 oz.) = P (z > [{x(avg.) - μ[tex]\sqrt{n}[/tex]}/σ])

                        = P (z > [{12.7 - 10[tex]\sqrt{120}[/tex]}/5.2])

                        = 1 - P ( z < 1.86)

                        = 1 - 0.862394

Answer:

if the base is on the x-axis, the width of the rectangle is = xif the height is based on the parabola, the length = 7-x^2

the area of a rectangle = length * width

thus, area = x*(7-x^2)= 7x-x^3

in order to maximize the area, you would need to take the derivative of the area and set it equal to 0

Area = 7x-x^3Area' = 7 - 3x^2

7-3x^2 = 0thus, x = 1.5275

this x represents the x needed to create the largest possible area with the given parameters.

Thus:Width (x-axis) = 1.5275Length (y-axis) = 7 - (1.5275)^2 = 4.6667

The value of y when x = 2 is 16/25 and when z = 6 is 200/36

The constant of proportionality is the ratio that relates two given values in what is known as a proportional relationship.

Given that, Y varies directly as x and inversely as the square of z and y=8 when x=25

That means, y ∝ x and y ∝ 1/z²

Let  constant of proportionality be k, then,

y = kx and y = k/z²

Now, finding k, when x = 25

8 = k25

k = 8/25

For x = 2,

y = 8/25X2

y = 16/25

Finding k when y = 5

8 = y/25

y = 200

Now, when z = 6

y = 200/36

Hence,  The value of y when x = 2 is 16/25 and when z = 6 is 200/36

The probability of drawing purple and green marbles will be 1/80.

The probability of an event occurring is defined by probability.

Probability is also called chance because if you flip a coin then the probability of coming head and tail is nothing but chances that either head will appear or not.

As per the given,

Number of purple marble = 5

Number of green marble = 1

Total marble = 5 + 6 + 8 + 1 = 20

Probability drawing a purple marble = 5/20

Probability of drawing a green marble = 1/20 (because the number of marble remain the same)

Probability of drawing a purple and green = 5/20 x 1/20 = 1/80

Hence "There is a 1/80 chance of drawing purple and green marbles.".
