The correct answer is option A. Which is the solution of the given equation will be (15,15).

What is an equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

Given equations are solved as:-

a - 1.2b = -3 or a = -3 + 1.2b

0.2a + 0.6b = 12

Put the value of a from equation 1 to the equation second.

0.2 ( -3 + 1.2 b) + 0.6b = 12

-0.6 + 0.24b + 0.6b = 12

0.84b = 12 + 0.6

0.84 b = 12.06

b = 15

Put the value of b in the first equation to find the value of a.

a = 1.2b - 3

a = (1.2 x 15) - 3

a = 15

Therefore the correct answer is option A. Which is the solution of the given equation will be (15,15).

if the area of a square is 32ft how long is the diagonal?

Answers

8 FEET LONG

A square has the same length all 4 sides, therefore in order to find the length of the sides, you would need to find the square root of 32, which would be 5.66 or 4 radical 2. Then to find the diagonal length you would need to split the square diagonally resulting in 2 triangles. We know the side lengths of the triangles but not the hypotenuse( longest side of triangle), which is the diagonal length. To figure this out we would use the Pythagorean theorem a^2 + b^2 = c^2. We know what a and b are so we substitute, do basic algebra, and find that c is equal to 8

Answer: 8

Step-by-step explanation:

To find the diagonal, we need to use two formulas:

Area of a square: [tex]A = s^{2}[/tex] (Area = side * side)

Pythagorean Theorem: [tex]a^{2} +b^{2} =c^{2}[/tex]

Since every side of a square is the same:

[tex]a^2 = b^2\\a = b = \sqrt{32} \\a^{2} = 32\\b^2 = 32[/tex]

Our equation:

[tex]32 + 32 = c^2\\64 = c^2\\8 = c[/tex]

Point M(5, 2) is the midpoint of segment XY. Point X has coordinates
(-4, 6). Find the coordinates of point Y

Please help!

Answers

Answer:

(14, -2)

Step-by-step explanation:

The coordinates of the midpoint is equal to the mean of the coordinates of the endpoints.

=============================================================

Solving :

⇒ 5 = -4 + x / 2

⇒ x - 4 = 10

⇒ x = 14

⇒ 2 = 6 + y / 2

⇒ y + 6 = 4

⇒ y = -2

===========================================================

Coordinates of Point Y :

⇒ Y = (x, y)

⇒ Y = (14, -2)

Answer:

Y (14, - 2 )

Step-by-step explanation:

using the midpoint formula for (x₁, y₁ ) and (x₂, y₂ ) , then

midpoint = ( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1+y_{2} } }{2}[/tex] )

equating the x- coordinates and the y- coordinates

let coordinates of Y = (x, y )

[tex]\frac{x-4}{2}[/tex] = 5 ( multiply both sides by 2 )

x - 4 = 10 ( add 4 to both sides )

x = 14

and

[tex]\frac{y+6}{2}[/tex] = 2 ( multiply both sides by 2 )

y + 6 = 4 ( subtract 6 from both sides )

y = - 2

coordinates of Y = (14, - 2 )

c. Find the average rate of change of M as t changes from 24 to 32.

Answers

The average rate of change of the number of miles with respect to the number of gallons is 14.5 miles per gallon

How to determine the average rate of change?

The given parameters can be represented as:

M(0) = 30680

M(20) = 30970

The average rate of change is calculated as:

M'(t) = (M(20) - M(0))/(20 - 0)

This gives

M'(t) = (30970 - 30680)/(20 - 0)

M'(t) = 14.5

Hence, the average rate of change of the number of miles with respect to the number of gallons is 14.5 miles per gallon

The average rate of change of M as t changes from 8 to 16.

This is calculated using

M'(t) = (M(16) - M(8))/(16 - 8)

M'(t) = (20 - 10)/(16 - 8)

M'(t) = 1.25

The average rate of change of M as t changes from 16 to 24.

This is calculated using

M'(t) = (M(24) - M(16))/(24 - 16)

M'(t) = (25 - 20)/(24 - 16)

M'(t) = 0.625

The average rate of change of M as t changes from 24 to 32.

This is calculated using

M'(t) = (M(32) - M(24))/(32 - 24)

M'(t) = (25 - 25)/(32 - 24)

M'(t) = 0

A bicycle company is designing women's bicycle frames. The frames can accommodate any woman taller than 54.5 inches. Given that the heights of adult American women are normally distributed, with a mean of 65 inches and a standard deviation of 3.5 inches, what percentage of American women CANNOT use the bicycles designed by this company

Answers

Using the normal distribution, it is found that 0.13% of American women CAN NOT use the bicycles designed by this company.

What is Normal Probability Distribution?

The z-score of a measure X of a normally distributed variable with mean and standard deviation is given by:

[tex]z=\dfrac{x-\mu}{\sigma}[/tex]

The z-score measures how many standard deviations the measure is above or below the mean.Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

The mean and the standard deviation are given, respectively, by:

[tex]\mu = 65\ \ \sigma= 3.5[/tex]

The proportion of women that cannot use the bikes(smaller than 54.5 inches) is the p-value of Z when X = 54.5, hence:

[tex]z=\dfrac{x-\mu}{\sigma}[/tex]

[tex]z = \dfrac{54.5-65}{3.5}[/tex]

Z = -3

Z = -3 has a p-value of 0.0013.

0.0013 = 0.13% of American women CAN NOT use the bicycles designed by this company.

Based on the property of the consecutive angles of a parallelogram, the value of x is calculated as: E. 37.

What are the Properties of the Angles of a Parallelogram?

In a parallelogram, the angles that are opposite to each other are congruent while consecutive angles are supplementary.

Angles F and G are consecutive angles and are therefore supplementary (have a sum of 180 degrees.)

Angle F + angle G = 180

4x - 2 + 34 = 180

4x + 32 = 180

4x = 180 - 32

4x = 148

x = 148/4

Answers

The total amount of money spent by Keesha to buy grapes and bananas is equal to $6.38.

How much did Keesha spend in all?

Based on the value of the bills and coins which represent the cost of each item, we would determine the total amount of money spent by Keesha to buy grapes and bananas.

For the grapes, we have:

Cost of grapes = 5 + (1 × 0.25) + (2 × 0.1) + 0.05

Cost of grapes = 5 + 0.25 + 0.2 + 0.05

Cost of grapes = $5.5.

For the bananas, we have:

Cost of bananas = (3 × 0.25) + 0.1 + (3 × 0.01)

Cost of bananas = 0.75 + 0.1 + 0.03

Cost of bananas = $0.88.

Question 6
5 pts

Answers

The rocket's height when the distance between you and the rocket is 100 feet is 98.9 feet

How to determine the rock's height?

The function is given as:

d = √216 +h²

At a distance of 100 feet, it means that:

d = 100

So, we have:

√216 +h² = 100

Take the square of both sides

216 +h² = 10000

Subtract 216 from both sides

h²= 9784

Take the square root of both sides

h = 98.9

Hence, the rocket's height when the distance between you and the rocket is 100 feet is 98.9 feet
