A whole hour or revolution is 60 minutes and 360° so the area of a sector is:
A/πr^2=α/360
A=απr^2/360...now we need to find the angle α/360=5/60, α=30° so:
A=30πr^2/360
A=πr^2/12 and r=11.25ft so
A=11.25^2*π/12
A≈33.13 ft^2
Answer:
x=14?
Step-by-step explanation:
2(x+4)=2x+8, so 3x-6=2x+8. Subtraxt 2x from each side to get x-6=8. Then add 6 to both sides to get x=14
Answer:
n = 10
Step-by-step explanation:
Solve for n:
(3 n)/5 = 6
Multiply both sides of (3 n)/5 = 6 by 5/3:
(5×3 n)/(3×5) = 5/3×6
5/3×3/5 = (5×3)/(3×5):
(5×3)/(3×5) n = 5/3×6
5/3×6 = (5×6)/3:
(5×3 n)/(3×5) = (5×6)/3
(5×3 n)/(3×5) = (3×5)/(3×5)×n = n:
n = (5×6)/3
6/3 = (3×2)/3 = 2:
n = 5×2
5×2 = 10:
Answer: n = 10
I believe that it is the second and third boxes
Answer:
6=2+2+2
Step-by-step explanation:
-In mathematics, a quaint number is a number that can be written as the sum of two or more prime numbers.
-The multiple divisors of 6 in a factor tree are 2,2 and 2
-6 can thus be written as 2+2+2:
6=2+2+2
-Hence 6 is a quaint number
