. The table shows the number of miles driven over time.

Mathematics
1 answer:
nika2105 [10]3 years ago
5 0

Answer: First option.

Step-by-step explanation:

You can find the rate by finding the slope.

The slope can be calculated with the following formula:

m=\frac{y_2-y_1}{x_2-x_1}

Then, you must choose two points from the table, substitute them coordinates into the formula and then evaluate.

Choosing the points (4,204) and (10,510), you can identify that:

y_2=204\\y_1=510\\\\x_2=4\\x_1=10

Making the substitution into the formula, you get that the slope is:

m=\frac{204-510}{4-10}\\\\m=\frac{-306}{-6}=\frac{51}{1}

Therefore, based on the unit rate obtained, you can conclude that your car travels 51 miles every 1 hour.

The perimeter of a rectangle is 128 inches.
Anuta_ua [19.1K]

Considering the perimeter of the rectangle, we have that the length is of 9 inches and the width is of 55 inches.

<h3>What is the perimeter of a rectangle?</h3>

The perimeter of a rectangle of length l and width w is given as follows:

P = 2(l + w).

The length is an odd integer and the width is <u>5 times the next consecutive odd integer,</u> hence:

l = x, w = 5(x + 2).

The perimeter is of 128 inches, hence:

128 = 2l + 2w

128 = 2x + 10(x + 2)

128 = 2x + 10x + 20

12x = 108

x = 9.

Hence the length is of 9 inches and the width is of 55 inches.
