Answer:

96 laps in 2 hours

Step-by-step explanation:

2 hours = 60min × 2

2 hours = 120 min

120 min ÷ 10 min for 8 laps = 12

12 x 8 = 96 laps in 2 hours

Answer:

96 laps

Step-by-step explanation:

2 hours = 2 * 60 = 120 minutes

So now the question would be as given below:

8 laps in 10 minutes so how many laps in 120 minutes.

Since, no. of laps and minutes are in proportion.

$\therefore \: \frac{8}{10} = \frac{x}{120} \\ \\ x = \frac{8 \times 120}{10} \\ \\ x = \frac{960}{10} \\ \\ x = 96 \:$

Bad Investment After Mrs. Fisher lost 9% of her investment, she had $22,750. What was Mrs. Fisher's original investment?

stira [4]

Answer:

$2500

Step-by-step explanation:

Given that,

The lost percentage = 9%

Amount she had = $22,750

We need to find Mrs. Fisher's original investment.

As she had lost 9%, it means she will remain with 91% of her investment. Let the original investment is x.

So,

$91\%\ of \ x=22,750\\\\\dfrac{91}{100}x=22,750\\\\x=\dfrac{22,750\times 100}{91}\\\\x=\$25000$

So, her original investment is equal to $25000.

The distance y (in centimeters) a spring is compressed by a force x (in kilograms) is given by

kirza4 [7]

Answer:

(x, y) = {(20, 1.3), (40, 2.6), (60, 3.9), (80, 5.2), (100, 6.5)}

Graph C represents the table of values

Step-by-step explanation:

To complete the table, substitute each value of x into the equation, $y = 0.065x$ , to find each corresponding y-value.

Thus:

✔️When x = 20:

$y = 0.065x$

$y = 0.065(20)$

$y = 1.3$

✔️When x = 40:

$y = 0.065x$

$y = 0.065(40)$

$y = 2.6$

✔️When x = 60:

$y = 0.065x$

$y = 0.065(60)$

$y = 3.9$

✔️When x = 80:

$y = 0.065x$

$y = 0.065(80)$

$y = 5.2$

✔️When x = 100:

$y = 0.065x$

$y = 0.065(100)$

$y = 6.5$

✔️<em>The graph of that represents this table of values is graph C. See attachment.</em>
