i dont want to assume all the other people participating in after school activities are girls but if they are, the answer is 108.
180 = 100%
x = 40%
the information above shows that 60% are girls
60% of 180 = 108 or 0.60 x 180 = 108
the answer is 108
hope this is helpful!
By definition. The volume of the sphere is:
V = (4/3) * (pi) * (r ^ 3)
Where,
r: radius of the sphere.
Substituting values:
2254 pi = (4/3) * (pi) * (r ^ 3)
Clearing the radio we have:
r ^ 3 = (3/4) * (2254)
r = ((3/4) * (2254)) ^ (1/3)
r = 11.91255883
Then, the surface area is:
A = 2 * pi * r ^ 2
Substituting values:
A = 2 * 3.14 * (11.91255883) ^ 2
A = 891.6 m ^ 2
Answer:
The surface area of the sphere is:
b. 891.6 m ^ 2
Answer:
n = 5/7 or 0.7
Step-by-step explanation:
The goal is to isolate the variable N. First, you distribute the fractions to their repsective parentheses.
1/2(5n + 8) = 3/4(12 - 6n)
2.5n + 4 = 9 - 4.5n
2.5n + 4.5n = 9 - 4
7n = 5
Divide both sides by 7, and you get n = 5/7 or 0.7
Answer:
b) ∠ACB = 25 degrees
Step-by-step explanation:
arc BA = 50° because central angle AOB = 50°
∠ACB is inscribed angle of 50°, so it is (1/2)(50) = 25°
