A runner runs 8 miles in 92 minutes. What is the runners unit rate?

KiRa [710]

For this case, what we must do is calculate the speed of the runner.

We have then that the speed is given by:

$v =\frac{d}{t}$

Where,

d: distance

t: time

Substituting values we have:

$v = \frac{8}{92}$

$V = 0.09 \frac{miles}{minutes}$

Answer:

the runners unit rate is:

$V = 0.09 \frac{miles}{minutes}$

Green Fencing Company will install the fence

LUCKY_DIMON [66]

The company would charge $837.50 to build the fence.

Installing a fence would cost $62.50 per hour.

It will take 13²/₅ hours to install this fence.

The cost would be:

= Cost per hour x Number of hours taken

Number of hours it would take should be converted to improper fraction to be multiplied:

13²/₅ = 67/5 hours

Cost is:

= 62.50 x 67/5

= $837.50

In conclusion, it would cost $837.50 to build the fence.

Write the radical below in the simplest radical form √210 Pls show ur work

Anna [14]

Answer:

$\sqrt{210}$

Step-by-step explanation:

Let's look at the prime factors of 210.

210 = 2 * 3 * 5 * 7

$\sqrt{210} = \sqrt{2 \times 3 \times 5 \times 7} = \sqrt{210}$

Since no factor appears more than once, this radical cannot be simplified.
