A $40 shirt now selling for $28 is discounted by what percent? A. 20% B. 30% C. 40% D. 60 %

Answers

Answer:

c

Step-by-step explanation:

The percent of discount on the shirt will be 30%.

What is the percentage?

The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol '%' is used to symbolize it.

The percentage is given as,

Percentage (P) = [Initial value - Final value] / Initial value x 100

A $40 shirt now selling for $28.

Then the percent of discount on the shirt will be

The final value of the shirt is $18 and the initial value of the shirt is $40.

Percentage (P) = [(40 - 28) / 40] x 100

Percentage (P) = [12 / 40] x 100

Percentage (P) = 0.30 x 100

Percentage (P) = 30%

Thus, the percent of discount on the shirt will be 30%.

two rectangular prisms have the same volume. The first prism has a length of 10 meters, a width of 6 meters, and a hight of 2 meters. The second prism has a length of 6 meters and a with of 4 meters.
what is the hight of the second rectangular prism?​

Answers

Answer:

5 meters

Step-by-step explanation:

If we want to get the volume of the first rectangular prism, it would be 6x10x2=120

So the second one must have the same volume of the second one, so for the second one, we have to 4x6x?=120

So if you want to get the "?" you have have to divide the 120 by 6 then 4, so the answer will be 5.

And if you are not sure if it's right then multiply 6,4 and 5 together and you will get 120.
