Roger ran eight laps around a mile track during PE on Monday. Answer each question in the space provided. Part A How many feet d
Gre4nikov [31]

Answer:

A) 10,560 ft. B) 32 more laps.

Step-by-step explanation:

A) Four laps around a track is equal to one mile, and there are 5,280 feet in one mile. If Roger ran eight laps, he ran two miles. Therefore: 5,280 ft. times 2, is equal to 10,560 ft.

B) We know that Roger ran two miles Monday. We also know that four laps around a track is equal to one mile. In order to run 10 miles, he would have to run 40 laps, and since he already ran 8, we can subtract that from 40. You are left with 32 more laps.

A chemical company makes two brands of antifreeze. The first brand is 45% pure antifreeze, and the second brand is 95% pure anti
Dimas [21]

Answer:

42 gallons 45% antifreeze

28 gallons 95% antifreeze

Step-by-step explanation:

If x is volume of 45% antifreeze, and y is volume of 95% antifreeze, then the total volume is:

x + y = 70

And the total amount of antifreeze is:

0.45 x + 0.95 y = 0.65 (70)

Solving by substitution:

0.45 x + 0.95 (70 − x) = 0.65 (70)

0.45 x + 66.5 − 0.95 x = 45.5

21 = 0.5 x

x = 42

y = 28

4. Sasha sells t-shirts. Each day she earns a set amount, plus a
zhannawk [14.2K]

Answer:

The linear function is: p(x) = 3x+65The linear function is: p(x) = 3x+65

Step-by-step explanation:

Let x be the number of t-shirts and y be the total pay

As we can clearly see in the table that there is a linear relationship between x and y

A linear function is given as:

y = mx+b

Here m is the gradient of the function then

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

Taking any two pairs of x and y

(1,68) and (2,71)

m = \frac{71-68}{2-1}\\m = 3

Putting in equation

y = 3x+b

Putting a pair (1,68) in the equation to find the value of b

68 = 3(1) + b\\68 = 3+b\\b = 68-3\\b = 65

Putting the value of b

y = 3x+65

Let p(x) be the linear function

Hence,

The linear function is: p(x) = 3x+65

PLEASE HELP
Margaret [11]

Answer:

$21

Step-by-step explanation:

First, find the price without the discount by adding 12 to 30:

30 + 12

= 42

To find the original cost of each game, divide 42 by 2

42/2

= 21

So, each game was originally $21
