If it is $4.00 per gallon then we need to find the price of 7 gallons.
7 * 4.00 = 28
so it costs $28 to travel 350 miles.
no to find the cost per mile, we need to divide.
350 / 28 = 12.5
so the cost to run the car per mile is $12.50
Answer:
a is 625 work: 5*5*5*5=625
b is 16807 work: 7*7*7*7*7=16807
c is 0.0625 work: .5*.5*.5*.5
d is 2744 work: 14*14*14
Step-by-step explanation:
a very fast way to do it:
Trivially 8.8*5>10, so the power of 10 is 6+2+1 = 9.
Therefore, the answer is
