He's driving 42mph. 42m/60h=0.7mpm. 12 minutes x 0.7 mile per minute= 8.4 miles. 21-8.4=12.6 miles left . 12.6 x 0.7= 8.86 minutes left or about nine
Answer:
It will take 1 5/7 hours
Step-by-step explanation:
3/4 of an hour is;
3/4 * 60 minutes = 45 minutes
3 1/2 acres is done in 45 minutes
8 acres will be done in x minutes
Thus, mathematically;
3 1/2 * x = 8 * 45
7x/2 = 360
7x = 2 * 360
7x = 720
x = 720/7 minutes
Let us convert this to hours
That will be;
720/7/60 = 720/(60 * 7) = 720/420 = 12/7
= 1 5/7 hours
Answer:
There are 52 such numbers that have even divisors.
Step-by-step explanation:
All the numbers between 2 and 59 have an EVEN number of positive divisors.
Except the Perfect Squares..
or 4, 9, 16, 25, 36 and 49, which have 3 divisors each.
So:
59 - 2 + 1 =58
Now subtract 58 from 6 (perfect squares)
58- 6=52
Therefore,it means that there are 52 such numbers that have EVEN divisors....
