Answer:
Haeather ran at a speed of 5 miles per hour.
Step-by-step explanation:
Given that last week at the park Haeather ran 4 miles in 48 minutes, to determine what was Haeather rate of speed in miles per hour the following mathematical calculation must be performed:
48/4 = 12
Thus, Haeather ran 1 mile every 12 minutes.
60/12 = 5
1 x 5 = 5
Therefore, Haeather ran at a speed of 5 miles per hour.
8(8-6v)= using the distributive property
8*8 = 64
8*6v = 48v
8(8-6v) = 64-48v
13/21 cause 21 is a common denominator and 7x3+ 21 you have to do 7x=7 and 3x7=21 so you have to do 3x2= 6 so you do 6+7 which equals 13 and your answer is 13 over 21 since it can't be simplified
The face dimensions are all the same, so the 3 lateral faces each have the same area. The lateral area is
3·(10 cm²) = 30 cm²
