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.

Please help me with this question.
insens350 [35]

Answer:

The correct answer is option C. 3/5= 0.60

Step-by-step explanation:

It is given that,the  Venn diagram shows sports played by 10 students.

event A = The student plays basketball.

event B = The student plays soccer

<u>To find P(A|B))</u>

P(A) = 6

P(B) = 5

P(A ∩ B) = 3

We have P(A|B) = P(A ∩ B)/P(B)

 = 3/5

 = 0.6

Therefore the correct answer is option C. 3/5= 0.60

Artemon [7]
For this case you can solve the problem by applying a simple rule of three in which we have
 520 ---> 100%
 800 ---> x

 Clearing x we have
 x = (800/520) * 100 = 154%
 the percentage increase in cost was
 154-100 = 54%
 answer
 the percentage increase in cost was 54%
