Choose the statement that is true and has a converse that is also true. O A. If the equation of a line is y = 3x + 2, then the slope of the line is 3.
O B. If x2 = 100, then x = 10.
O c. If x – 1= 8, then x = 9.
O D. If an angle measures 45 degrees, then the angle is acute.

c. If x – 1= 8, then x = 9.

Step-by-step explanation:

the statement is true, and if you switch it around it still makes sense.

"if x=9, then x-1=8"

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

5
