Step-by-step explanation:
Answer:
275 miles in 5 hours
55 miles in one hour
Check
to check if im right
275×2 would be how many miles she drove in 10 hours rght ? 275×2=550
550 miles in 10 hours
we know one hour is 55 miles & 5 hours is 275 & 10 hours is 550
10 hours plus 3 hours = 13 hours right ?
55 ×3 = 165
550 +165=715
715 miles in 13 hours
Step-by-step explanation:
715÷13 to get how many miles she drove in one hour .
=55 miles in 1 hour .
then multiply 55 ×5 to get how many miles she drove in 5 hours
55×5=275
275 miles in 5 hours
4% means <span>4100</span> 'of' means multiply so:
<span>363.99⋅<span>4100</span></span> is <span>363.99⋅4</span> = 1455.96
<span>1455.96100</span> = 14.56 (rounded up)
<span>363.99+14.56=$378.55</span> to the nearest cent.
10 is the answer.
You know that there are 4 numbers and you have to add the numbers then divide them by four to get the mean. So all you have to do is reverse the steps, multiply 30 by 4 to get 120, then add 12+50+48 to get 110. Then subtract, 120-110=10. To check if it is correct add 12, 50, 48, and 10 to get 120, then divide by 4 to get 30. And voila, there is the answer. I hope this helped for future problems like this one.
