Sphere a has a radius of 24 centimeters, and sphere b has a diameter of 42 centimeters. the radius of sphere a is multiplied
what factor to produce the radius of sphere b?
- 4/7
- 7/8
- 8/7
- 7/4

answer:

7/8

step-by-step explanation:

a's radius = 24

b's radius = 42/2 = 21

21/24 = 7/8

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
