Answer:

$292.5

Step-by-step explanation:

First you have to find x:

202.50 = 9x

x= 202.5/9

x= 22.5

------------------------------------------------------------------

Now you have to add the 4 students, or 4x

y=9x + 4x

y = 13x

y = 13(22.5)

y = 292 . 5

Hope this helps!!!

a gas company in massachusetts charges $1.30 for 16.7 ft3 of natural gas. convert this rate to dollars per liter of gas
Katyanochek1 [597]

By using a change of units, we can see that the rate in dollars per liter is:

R = $0.0027 per liter.

<h3>How to convert the rate?</h3>

Here we have a rate in dollars per cubic foot, and we want to rewrite this in dollars per liter. So we just need to apply a change of units.

The original rate is in dollars per square foot, and it is given by:

R = $1.30 for 16.7ft^3

We know that the relation between cubic feet and liters is:

1ft^3 = 28.32 L

Then, if we apply a change of units, we can rewrite the volume as:

16.7ft^3 = 16.7*(28.32) L = 472.9 L

Then the rate is $1.30 per 472.9 L, taking the quotient we get:

R = ($1.30/472.9 L) = $0.0027 per liter.

Pleaseeeee answer correctly !!!!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!!!!!
Lelu [443]

Answer:

45 miles

Step-by-step explanation:

Use the Pythagorean Theorem. Imagine a line connecting the ends of the right angle you made by driving. It would make a right triangle. You are trying to find the hypotenuse. Use the formula a^{2} +b^{2} =c^{2}. Square 27, or multiply 27 by 27, to get 729. Add this to the square of 36, 1296. So c^{2} = 2025. Find the square root of 2025. \sqrt{2025} = 45. Hope this helped ^^
