Answer:
you have to use the Pythagorean theorem. a^2 + b^2= c^2
72^2 + b^2 = 75^2
5184 + b^2 = 5625 (subtract 5184 from both sides)
b^2= 441 (find the square root of each side)
b= 21
Answer:
10 gallons of gas.
Step-by-step explanation:
250/9 = how many miles 1 gallon of gas will take
250/9 = 27.78
1 gallon of gas = 27.78 miles
275/27.78 = 9.90 gallons
9.90 gallons round up to 10 gallons
Therefore, Trey would need 10 gallons of gas to drive 275 miles.

Step-by-step explanation:
Answer: 4:00 pm
Step-by-step explanation:
I was taught to get a common denominator and then arrange them in the correct order.
So first you find out what all the denominations can be multiplied to. That would be 40
So you multiply the bottom of each fraction by a number that will get 40.
3/4 * 10 = 30/40
7/8 * 5 = 35/40
3/5 * 8 = 24/40
Then you get 30/40, 35/40, and 24/40.
Then you organize the m.
24/40, 30/40, and 35/40
