The <u>correct answers</u> are:

A) the number of different colors on the page; and
D) half the speed of the car.

Explanation:

A variable represents an unknown amount.

For A, we do not know how many colors are on the page; this means we would use a variable to represent it.

For D, while we know we want half of the speed of the car, we do not know what the speed of the car actually is; therefore we would use a variable to represent it.

If the nurse to patient ratio is 3:15, how many nurses would you expect to see in a unit with 37 patients?

Yanka [14]

If there are 3 nurses to every 15 patients, that means there is 1 nurse to every 5 patients since we can divide by 3 to simplify the ratio.
in order to find how many nurses would care for 37 patients, we can divide by 5.
37/5 = 7.4 nurses.
however, we cannot have .4 of a nurse, so you can either say 7 nurses or 8 nurses, but 7.4 rounds down to 7.

The lengths of the four sides of a quadrilateral (in centimeters) are consecutive

My name is Ann [436]

The longest of the four side lengths is 24 cm

<h3>How to find the value of the longest of the four side lengths?</h3>

The given parameters are:

Perimeter, P = 90 cm

The lengths are consecutive integers

Let the smallest be

Smallest = x

So, we have

P = x + x + 1 + x + 2 + x + 3

Evaluate the like terms

P = 4x + 6

Substitute P = 90 cm in P = 4x + 6

4x + 6 = 90

Subtract 6 from both sides

4x = 84

Divide by 4

x = 21

The longest side is

Longest = x + 3

This gives

Longest = 21 + 3

Evaluate

Longest = 24

Hence, the longest of the four side lengths is 24 cm
