In the rectagular prism shown below, GH is parallel to EF. If the equation of GH is 6y-x=2, could the equation of EF be 4=y-1/6x

ASHA 777 [7]

Answer:

Yes

Step-by-step explanation:

Given

GH:

$-6y - x = 2$

Required

Can EF be

$4 = y - \frac{1}{6}x$

First, we determine the slope of GH

$-6y - x = 2$

Solve for 6y

$6y = -x - 2$

Solve for y

$y = -\frac{1}{6}x - \frac{2}{6}$

$y = -\frac{1}{6}x - \frac{1}{3}$

An equation has the form:

$y =mx + b$

Where

$m = slope$

By comparison:

$m = -\frac{1}{6}$

Next, determine the slope of EF

$4 = y - \frac{1}{6}x$

Make y the subject

$y = -\frac{1}{6}x + 4$

The slope is:

$m = -\frac{1}{6}$

Compare the slopes of both lines.

$m=m = -\frac{1}{6}$

Since they have the same slopes, then the equation of EF is possible

A company pays $3.91 million to air a 30- second commercial during a football game that is watched by approximately 115 million

Radda [10]

Answer:

Part 1) The cost per second is $\$130,333.33$

Part 2) The cost per customer is $\$0.034$

Step-by-step explanation:

Part 1) Calculate the cost per second

we know that

To find out the cost per second, divide the total cost by the time

Let

x ----> the total cost

y ----> the time in seconds

we have

$x=\$3,910,000$

$y=30\ sec$

$\frac{\$3,910,000}{30}=\$130,333.33$

therefore

The cost per second is $\$130,333.33$

Part 2) Calculate the cost per customer

we know that

To find out the cost per customer, divide the total cost by the number of customers

Let

x ----> the total cost

y ----> the number of customers

we have

$x=\$3,910,000$

$y=115,000,000\ customers$

$\frac{\$3,910,000}{115,000,000}=\$0.034$

therefore

The cost per customer is $\$0.034$

the area of rectangular park is 3/5 square mile, the length of the park is 7/8 mile,what is the width of the park

Luba_88 [7]

Area=LengthxWidth so 3/5=7/8xWidth. To get width by itself you must divide both sides by 7/8. When dividing fractions you can flip the fraction and multiply so multiply (3/5)(8/7). To do this just multiply the numerators and denominators to get 24/35 so width = 24/35
