A car has 15 gallons of gas in its tank. The car travels 35 miles per gallon of gas. It uses 135 of a gallon of gas to go 1 mile.

1. How far can the car travel with 15 gallons?

Answers

Answer:

525 miles

Step-by-step explanation:

Two unit rates are given in this problem:

miles per gallongallons per mile

Since we want to find miles, the appropriate rate to use is miles per gallon:

distance = mile/gallon x gallons

distance =35 miles/gallon x 15 gallons = 525 milles

The car can travel 525 miles on 15 gallons of gas.

Find the percent of change from 6,570 pt to 16,425 pt.

Answers

Answer:

Percentage Change | Increase and Decrease

First: work out the difference (increase) between the two numbers you are comparing.

Increase = New Number - Original Number.

Then: divide the increase by the original number and multiply the answer by 100.

% increase = Increase ÷ Original Number × 100.

Step-by-step explanation:

hopefully this helped and you can find the percent change.

I think you would do
6,570 divided by 16,425
And that would get you
0.4%

I need help with a math question but apparently everyone is dead today..


the problem is down there and answer choices

A.

102 cm2


B.

76 cm2


C.

96 cm2


D.

108 cm2

Answers

The answer is D. I’m assuming this is surface area so here’s my explanation:) ok so the area of the triangle is 6 (4x3 divided by 2) and when you add the other triangle that’s 12. Ok so we have 12 so far. Then the area of the bottom rectangle is 24 (3x8). Then the area of the side rectangle is 32 (4x8). THEN the top rectangle’s area is 40 (8x5). When you add the numbers up (12+24+32+40) you get 108! And of course dont forget the cm2. ( centimeters squared ). :) I hope this helps

Step-by-step explanation:

1. Use this formula V=lwh

0.5 x 0.4 x 0.15 = 0.03

That is the volume of the lower prism

2. Do V=lwh again for the volume of the upper prism

0.5 x 0.15 x 0.2 = 0.015

3. After that add both of them up together

0.015 + 0.03 = 0.045

What is the value of b. If A+B=C and A=35 and C=25
Explain how you got this answer

Answers

Answer:

[tex]B=-10[/tex]

Step-by-step explanation:

Hi!

So let's write the equation again

[tex]A+B=C[/tex]

The next step is to plug in known values:

[tex]35+B=25[/tex]

Now we solve this as a normal algebra equation:

Do same to both sides

[tex]B = 25-35[/tex]

[tex]B=-10[/tex]

I hope this helped. Let me know if you have any questions

The answer is -10. No positive number could equal 25 and if 35-25 is 10, it would only make sense to be negative. Say if you have $25 but you need 35, you’d be in debt of $10 you borrowed from someone else. Hope this makes sense, I’m not the best at explaining.
