Answer:
2/4
Step-by-step explanation:
Rise over run. you go up 2 and right 4
$1 = 2 weeks
-
<u>Multiply by 800:</u>
$1 x 800 = 2 x 800 weeks
$800 = 1600 weeks
-
Answer: You need <u>1600 weeks </u>to get $800
A = {1, 3, 5, 7, 9)<br>

Answer:
{1, 3, 5, 6, 7, 9}
Step-by-step explanation:
A u (B n C)
First we look at
(B n C)
n indicates intersects. Intersects means the common. The common number in B and C, we have
{6}
Now A u {6}
u means union. That is, joining both sets together, hence, we have
{1, 3, 5, 6, 7, 9}
A u (B n C} gives {1, 3, 5, 6, 7, 9}
Answer:
31.41ft
Step-by-step explanation:
the area A of a circle is πr² = 78.5 square feet
3.1416* r² = 78.5
r² =78.5/3.1416 = 24.987
r = √24.987 = 4.999ft
the circumference C of a circle is 2πr
C = 2* 3.1416 * 4.999 = 31.41ft
