Astore is having a 20% off sale. if the reduced price of an item is $114.40 what was the original price?

143

Step-by-step explanation:

Let x = original price

20% of the original price is .2x

We get 20 % off so we subtract it from the original price

x- .2 x

That is equal to 114.40

x-.2x = 114.40

Simplify

.8x = 114.40

Divide each side by .8

.8x/.8 = 114.40/.8

x = 143

The original price is 143

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "

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
