Answer:
x=e^2/5
Step-by-step explanation:
log(20 x) - log(4) = 2
Add log(4) to both sides:
log(20 x) = 2 + log(4)
Cancel logarithms by taking exp of both sides:
20 x = 4 e^2
Divide both sides by 20:
And we get Answer:
x = e^2/5
Answer:
Well, Those best choice will be is: A. The area of a circle depends on the length of the radius.
B. The area of a sector depends on the ratio of the central angle to the entire. D. The area of the entire circle can be used to find the area of a sector. E. The area of a sector can be used to find the area of a circle. Hope This Helps!!~
Answer:
Step-by-step explanation:
1+2 = 3
12/3 = 4
so for the "1" you get 4
for the "2" you get 8
Answer:
144°
Step-by-step explanation:
step 1
Find the measure of the central angle of the regular pentagon
Divide 360 degrees by 5 (the number of sides)
Let
c----> the center of the pentagon
we know that
m∠ECA=72°
m∠ACB=72°
therefore
m∠ECB=m∠ECA+m∠ACB
substitute the values
m∠ECB=72°+72°=144°
The measure of angle ECB is equal to the degrees that the pentagon rotate
It takes 144 minutes to deliver 72 papers
