The answer for the first question is D.
here's why: John goes 60 miles an hour so to go 240 miles is 4, and to 30 miles is 30 minutes. so that would mean it would take him 4.5 hours ( 4 hours and 30 minutes. )
The answer to the second question is C.
here's why: since each of the workers mow at the same speed, there's no need to worry about the 9. now you just need to divide 45 by 10 ( 4.5 ) to see how many lawns he mows in an hour ( 4.5 )
Answer:
Step-by-step explanation:
The solution to the problem is as follows:
Tan(sqrt(3)/3) * sqrt(3)/sqrt(3) = 1/sqrt (3)
therefore θ = 3 0 degrees = <span>Π/6

The formula is L*W*D, right?
So for the cube, since all sides are equal then the Length, Width and Depth would all be 8 unless otherwise specified. 8*8*8=512
The rectangle would be 10*2*3&1/2 or 10*2*3.5=70
I hope this is correct but if you want check my work with a calculator to make sure.
