The equation below shows the area of a trapezoid, a, with a height of 9 cm, and one base 35 cm.

a = 9 over 2(b + 35)

which of the following formulas correctly solves for the other base, b?

b = 2a over 9 + 35

b = 2 multiplied by a over 9 - 35

b = 2 multiplied by a plus 35, all over 9

b = 2 multiplied by a minus 35, all over 9

Apiling for a high-rise building is pushed by two bulldozers at exactly the same time. one bulldozer exerts a force of 1250 pounds in a westerly direction. the other bulldozer pushes the piling with a force of 2650 pounds in a northerly direction. what is the direction of the resulting force upon the piling, to the nearest degree? a. 65 n of w b. 25 n of w c. 45 n of w d. 35 n of w

Abucket of paint has spilled on a tile floor. the paint flow can be expressed with the function p(t) = 6(t), where t represents time in minutes and p represents how far the paint is spreading. the flowing paint is creating a circular pattern on the tile. the area of the pattern can be expressed as a(p) = 3.14(p)^2 part a: find the area of the circle of spilled paint as a function of time, or a[p(t)]. show your work. part b: how large is the area of spilled paint after 8 minutes? you may use 3.14 to approximate pi in this problem.

Which of the following parabolas opens up?
