Equation for circumference is c = 2(pi)r
r = 1/2(d)
d = 20
So…. r = 1/2(20) = 20/2 = 10
Going back to circumference equation
c = 2(pi)(10) = 2(3.14)(10) = 62.8
Answer: B
Explanation: Baseballs(b) minus 3 which is b-3
Do 6/30 and you will get .2lbs a day.
x=number of oranges.
y=number of bananas.
$5
we can suggest this system of equations:
x+y=12
0.5x+0.25y=5
We can solve this system of equations by substitution method.
x=12-y
0.5(12-y)+0.25y=5
6-0.5y+0.25y=5
-0.25y=5-6
-0.25y=-1
y=-1 /- 0.25=4
x=12-y
x=12-4=8
