Answer:

A) 40

B) 20

Step-by-step explanation:

By <em>Length · Width · Height</em>

A)  (5) · (4) · (2) = 40

For part B, the length and width are the same, but the depth (height) of the water is only one foot, so we can replace the height value from the first equation with 1.

B) (5) · (4) · (1) = 20

The area of a rectangle is 65 m2 , and the length of the rectangle is 3 m less than twice the width. find the dimensions of the
salantis [7]
X = <span>width
2x-3 = </span><span>length 

</span>x(2x-3) = 65\\&#10;2x^2 - 3x - 65 = 0 \\ D=b^2-4ac=(-3)^2-4*2*(-65)=529\\&#10;x_{1,2}= \frac{-bб \sqrt{D} }{2a}= \frac{3б 23}{4} \\ x_1=-5  \ \ \O \\ x_2=6.5 \ \

width = 6.5 m
length  = 2x-3 = 2*6.5 - 3 = 10 m

Hey there,

Given the question it shows that Ryann swam 1/4 of 14 miles that he was supposed to swim.

In words of is another way to say 1/4 * 14...

This expressed as a mixed number would be...

Of the 14 miles that Ryann was supposed to swim he swam 3 1/2 miles.

Hope I helped,
