We know that
area of circle =pi*r²
for r=4 ft
area=pi*4²------> 16*pi ft²
<span>the shaded sector of the circle represent 3/4 of the total area
so
3/4*16*pi-----> 12*pi ft</span>²
the answer is
12*pi ft²
Answer:
s=40
Step-by-step explanation:
Combine s and 1/2.
150−s/2=120+1/4s
Combine 1/4and s.
150−s/2=120+s/4
Move all terms containing s to the left side of the equation.
150−3s/4=120
Move all terms not containing s to the right side of the equation.
−3s/4=−30
Multiply both sides of the equation by −4/3.
−4/3 x (−3s/4)=−4/3 x−30 => S=40
Answer:
Step-by-step explanation:
First times the total by 1.05, by (1 + the rate of change which in this case is .05)
24.20 x 1.05 = 25.41
Then add the tip
25.41 + 5 = $29.41
$29.41 is your final answer
Answer:
Sophia's time was either 6 above or 14 below the average
Step-by-step explanation:
We know two things about the time:
1. Jacob was 4 mins below average
2. Sophia was 10 minutes different than Jacob
We don't know if she was quicker or slower, however. So we can work out both.
We can take Jacob's time as -4 since he was 4 BELOW the average. If we take -4+10 this would represent if Sophia was faster than Jacob.
-4+10=6.
Now the other way. -4-10=-14.
