Answer:
Step-by-step explanation:
28 + 8x = 8x + 24 + 2
28 + 8x = 8x + 26
28 ≠ 26

Answer:
She'll have to pay $46.75
Step-by-step explanation:
42.50 divided by 10% is 425 which equals $4.25. 42.50 + 4.25 = 46.75
42.50 + 10% = 46.75. So therefore you can check your answer twice and it will be the same answer.
Volume of the sphere = 3/4 pi r^3
The spheres radius is one third of the hemisphere's so radius of hemisphere = 3r
Volume of the hemisphere = 1/2 * 4/3 pi (3r)^3
= 2/3 * 27 pi r^3
= 18 pi r^3
So vol hemisphere / vol sphere = 18 pi r^3 / 4/3 pi r^3 = 18 * 3/4 = 13.5
Hemisphere is 13.5 times the volume of the sphere.
