A flower garden is shaped like a circle. Its diameter is 30 yd. A ring-shaped path goes around the garden. Its outer edge is a circle with diameter 36 yd.
The gardener is going to cover the path with sand. If one bag of sand can cover 6 yd, how many bags of sand does the gardener need? Note that sand comes
only by the bag, so the number of bags must be a whole number.

Find the condition that the zeros of the polynomial f(x) = x^3+3px^2+3px+r may be in a.p.

Multiplying fractions by whole number 5 x 1/3=?

Kevin has a spinner that has 10 equal sections and 2 sections of each color—red, blue, green, yellow, and purple. kevin spins the spinner 180 times. kevin determines about how many times the spinner will land on red or green, and his work is shown below. -kevin has the formula reversed; it should be the total number of sections over the number of red or green sections. -kevin should have used a 4 in the numerator because there are 2 red sections and 2 green sections. -kevin should multiply by the number of sections in the spinner rather than the total number of spins. -kevin calculated the prediction correctly and did not make any mistakes.
