Answer:
It will take 11 minutes per mile
Step-by-step explanation:
If he wants to run all the miles equally, just divide 55 by 5 to get an equal amount of minutes.
-9 -4x = 7
add 9 to both sides in order to isolate the x
-4x = 16
divide by -4
x = -4

Answer:
314 m²
Step-by-step explanation:
the formula for the surface area of a sphere (As) is
As = 4×pi×r²
the radius r (half of the diameter) is clearly indicated as 5m.
so, As = 4×3.14×5² = 4×3.14×25
I don't even need a calculator for this, as 4×25 = 100
so, As = 100×3.14 = 314
(you know, when multiplying by 10, the decimal point moves right one position. multiply by 100 it moves 2 positions, and so on).
