Charmaine bought a desktop computer and a laptop computer. Before finance charges, the labtop cost $450 less than the desktop. She paid for the computers using two different financing plans. For the desktop the interest rate was 7% per year, and for the labtop it was 5.5% per year. The total finance charges for one year were $279. How much did each computer cost before finance charges?​

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

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

t= 1/3.

hope this .

step-by-step explanation:

this is a good question! i'll do some research and come back when i have the answer!
