Person A spends $9.80 on gas. The car drives 27 miles per gallon and the driver drives 135 miles.

Person B's car gets 29 miles per gallon and spends $14.28 on gas to drive 203 miles.

If person A spends $13.72 on gas at the same rate, and person B spends $16.32 on gas, what is the difference in the amount of miles the cars can travel before running out of gas?

Answers

I think the answer is $72.52

Car B can drive 43 more miles than car A before running out of gas

Car A= $1.96 per gallon
Car B= $2.04 per gallon

Car A- 7 gal. x 27 mi./gal= 189 mi.
Car B- 8 gal. X 29 mi./gal= 232 mi.

232-189= 43

The length of an island is changing at the rate of –17 inches per year. How long will it take for the change in the length of the island to be –255 inches?

Answers

Answer:

15 years

Step-by-step explanation:

-255/-17=15

Based on the future dates concept, and the available content of the question, it will take 15 years for the change in length of the island to be -255 inches.

What is the Future date?

Future date is a term that is used to describe the major activities of a certain place or humans.

In this case, the time it takes for the change in length to be -255 inches we can set up the following equation:

Change in length = rate * time

-255 inches = -17 inches/year * time

To solve for time divide both sides of the equation by -17 inches/year:

time = -255 inches / (-17 inches/year)

Simplifying the expression:

time = 15 years

Therefore, in this case, it is concluded that it will take 15 years for the change in length of the island to be -255 inches.

Melissa wants to buy a new pair of shoes that have an original price of $45. Melissa has a coupon for 20 percent off to use on them, which amounts to a discount of $9. If sales tax is 9 percent on the final price of the shoes, how much tax will she need to pay?
$3.24
$4.05
$4.86
$4.95

Answers

Answer:

$3.24

Step-by-step explanation:

First, we subtract the $9 from the $45, so that equals $36

9% of the 36% is added to the final price as tax

36 x 0.09 = 3.24

Answer:

45-9=36

what we could do is first find out how much 1% is, 36÷1=0.36.

so 0.34×9=3.24

the final answer is 3.24

So first you gotta convert 2 2/5 into and improper fraction which gives you 12/5. Which brings you to 12/5 x 5/7, you’re gonna wanna cross cancel the most common factor which is the number 5 and that leaves you to build up the fraction 12/7. Now you wanna convert your improper fraction to a mixed number, and you do that by putting it in long division form otherwise said as 12 divided by 7 which leaves you with 1 and a remainder of 5. 1 5/7 is your answer
If your problem is a fraction I can help… 1 5/7
