Your family Used two full tanks of gasoline on a road trip. Your car drives about 25 miles per gallon on a road trip. Your car drives about 25 miles per gallon and the tank holds 12 gallons of gasoline. 1. Find the Approximate Number of gallons of gasoline used on the trip.

2. Find the approximate Number of miles you drove on the trip.

3. Assume Gasoline costs $4.50 per gallon. How much did you spend per mile on Gasoline?

4. You have $60 to spend on gasoline for another trip. The trip is 350 miles. You spend the same amount per mile on gasoline as on the first trip. Do you have enough money for gasoline? Explain

Please explain how to get the answer. In simple words please so I can understand.

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
