Answer:
<GOJ
Step-by-step explanation:
O is the center of the circle
So central angle is <GOJ
0.0392 or 3.92%
The exponential growth formula can find the interest rate.
y - tolat value (P +I) (216)
a - principal (200)
r- rate (unkown)
x - time in years (2 yrs)
Substitute known values
divide both sides by 200
take the square root of both sides
subtract 1 on both sides
r = 0.0392 or 3.92%
Answer:
$14.40
Step-by-step explanation:
She spent 12 dollars and has 1/5 left.
This means $12 is 4/5 of her original money.
$12=4/5 of the original money
$12+ $[12•(4/5)]=4/5+ (1/5)
$12+$[2.4]=5/5
$14.4=5/5 of the original money
She originally had $14.40
Answer:
A =28 pi cm^2
Step-by-step explanation:
First find the area of the larger circle
A = pi r^2
A = pi (8)^2
A = 64 pi
Find the area of the smaller circle
A = pi r^2
A = pi 6^2
A = 36 pi
The shaded area is the larger circle minus the smaller circle
A shaded = 64 pi - 36 pi
A =28 pi cm^2
