Cory earns $20 for every lawn he mows and $9 for every hedge he trims. he uses the expression 20x + 9y to keep track of his earnings. part a: identify the coefficients and variables in the expression. part b: how many terms are in the expression, what are they, and how do you know? part c: which term in the expression shows the total earned from trimming hedges? .

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

2/3

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves
