20 000 * 0.08(8%)= 1600
1600 * 20(years) = 32 000
Therefore you would have $32 000 after 20 years
Substitute each value until the answer is correct
a. 1 = -4 x -5 -1
1 does not equal 19
b. 15 = -4 x 4 -1
15 does not equal -17
c. -5 = -4 x 1 -1
-5 equals -5
just to make sure the last answer is incorrect
d. -7 = -4 x 2 -1
-7 does not equal -9
A). Pi m
Explanation:
Arc length formula:
Arc length = (Ø/360°) * 2*Pi*r
Ø = given angle (degrees)
r = radius
Plug given numbers in:
(45°/360°)* 2* Pi * 4
This will give you the answer of Pi
12 * 20% = 12 * 0.20 = 2.4 hours
It will not last his entire shift.
