Kathy is deciding on her schedule for next semester. She must take each of the following classes: English 101, Music 101, Biology 102, and Math 120. If there are 15 sections of English 101, 10 sections of Music 101, 12 sections of Biology 102, and 13 sections of Math 120, how many different possible schedules are there for Kathy to choose from? Assume there are no time conflicts between the different classes.

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

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
