6. the length of one base of a trapezoid is 19 less
than five times the length of the other base. if
the trapezoid has a height of 18 feet and an area
of 477 ft? , find the length of the longer base.

b1 = 41

Step-by-step explanation:

Area = (b1 + b2)*h/2

b1 = 5*b2 - 19

b2 = b2

h = 18

Area = 477

(5*b2 - 19 + b2) *h/2 = 477

(6b2 - 19)*18/2 = 477

(6b2 - 19)*9 = 477

(6b2 - 19) * 9/9 = 477/9

(6b2 - 19) = 53

6b2 - 19 + 19 = 53 + 19

6b2 = 72

b2 = 12

b1 = 5*b2 - 19

b1 = 60 - 19

b1 = 41

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

126 maybe. sorry
