Answer:
The radius, r₂, of the ball that uses one-half the amount of rubber coating used to cover the 16-inch ball is approximately 4.66 inches
Step-by-step explanation:
The dimension of the ball with known radius = 16-inch
The surface area of the ball with 16-inch radius = 4×π×r² = π·D² = π×16² = 804.24772 in.²
Given that the ball uses one-half the rubber material coating used to cover the 16-inch ball, we have the surface area of the ball = 804.24772 in.²/2 = 402.12386 in.²
The radius, r₂ of the new ball is found as follows;
402.12386 in.² = 4×π×r₂²
r₂² = 402.12386 in.² /(4×π) ≈ 32
r₂ = √32 = 4·√2 ≈ 4.66 inches
The radius, r₂, of the ball that uses one-half the amount of rubber coating used to cover the 16-inch ball ≈ 4.66 inches.
It is pretty simple,
All you have to do is multiply 75,000 by 0.0145 to find the amount of Medicare taxes
75,000x0.0145=1,087.50
The answer is that Jennifer pays $1,087.50 for Medicare taxes
I hope this helps
Answer:
7.5
Step-by-step explanation:
It is greater because it is closer to 8.
4x+2(-2x+1)=-3
4x-4x+2=-3
2=-3 is not a true statement.
The answer is no solution
