Answer:
The diameter of a circle with an area of 100 square miles is 20/√π miles.
Step-by-step explanation:
Area =100 = πr^2.
diameter = d = 2r.
100 = πr^2.
100/π = r^2.
√(100/π) = r.
10/√π = r.
d = 2r.
d = 2 * 10/√π.
d = 20/√π

Answer:
6
Step-by-step explanation:
first, we start with 2 dozen = 2 * 12 = 24 cookies
next, cole eats 2/3 of the cookies
2/3 of the cookies = 2/3 * 24 = 16
we are then left with
original # - # of cookies cole ate = 24 - 16 = 8
next, jim eats 1/4 of the cookies left
cookies left = 8
1/4 of cookies left = 1/4 * 8 = 2
cookies left - cookies jim eats = cookies still in jar = 8 - 2 = 6
20% of 850 was paid in cash..
0.20(850) = 170 was paid in cash
so (850 - 170) = 680 was not paid in cash
You could calculate how large something is if you only have one half measure?
