Alika [10]

Answer:

The volume of the new crate is exactly 174.4% of the old crate.

Step-by-step explanation:

Volume of a rectangular prism:

The volume of a rectangular prism of dimensions x, y and z is given by:

V = xyz

She decided that the dimensions of the new crate needs to be increased by 40% of the original length.

Each dimension is increased by 40%, which means that each is multiplied by 1 + 0.4 = 1.4. So

V = 1.4x(1.4y)(1.4z) = (1.4)^3(xyz) = 2.744(xyz)

Percentage:

The new volume is 2.744 the original volume. Considering the original volume is 100% = 1, it increased by 2.744 - 1 = 1.744 = 1.744*100% = 174.4%.

The volume of the new crate is exactly 174.4% of the old crate.

Sveta_85 [38]

Answer:

The length of the board is 60 inches. It's cut into two parts so that the longer piece is 5 times of the shorter part. The equation is formed as under...

Let's assume the shorter part is … x then the longer part is... 5x. The total parts are..

x + 5x = 6x and given that 6x is equal to 60 inches. Therefore...

If 6x = 60 inches then

x = 60/6 = 10 inches and the longer piece is 5x = 5.10 = 50 inches.

The shorter piece is 10 inches long and the length of the longer piece is 50 inches. Answer. Thanks.
