There are 24 students in science class. mr james will give each pair of students 3 magnets . so far ,mr james has given 9 pairs of students their magnets . how many magnets doses mr james need sp that each pair of students has exactly 3 magnes?

24/2 = 12 pairs of students

 if he gave 9 pairs of students magnets there are 12-9 = 3 pairs left

3 magnets per pair

3*3 = 9 more magnets are needed

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

step-by-step explanation:

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
