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:
4
Step-by-step explanation:
We know that all lengths in a rhombus are equal so we make the 2 equations equal to each other, then solve for x:



x=4
Answer:
$40.20
Step-by-step explanation:
60 / 100 = 0.6
0.6 x 33 = 29.8
60 - 29.8 = 40.2
Thus he price after the discount would be $40.20
Step-by-step explanation:
y=mx+b
y=-6x+b
3=-6(-1)+b
b=-3
y=-6x-3
Answer:
x=-2
Step-by-step explanation:
-4x - 8 = -4 • (x + 2)
