Last question of a really important test! i really need some ! a hollow ball is made of rubber that is 1 centimeter thick. the ball has a radius of 5 centimeters at the outside surface. what is the approximate volume of rubber used to make the ball? use 3.14 for pi. 255.4 cm³ 267.9 cm³ 523.3 cm³ 2043.1 cm³

One positive number is 9 more than twice another. if their product is 95, find the numbers

List the sides of δrst in ascending order (shortest to longest) if: m∠r =x+28°, m∠s = 2x+16°, and m∠t = x+12

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
