Answer:

this is school work

Step-by-step explanation: sorry but you gotta figure this out yourself.

but, the thing is that you should figure out the stuff inside the (these -->) then figure out the rest step by step like this, x= what then try to understand y= what, then use them to answer the problem.

and if its like this 1(4x + 5y) that mean that 9xy times 1 is your answer, this is an example.

Jared and Pedro walk 1 mile in about 15 minutes. They can keep up pace for several hours. About how far they walk in 65 minutes

VladimirAG [237]

<h2><u>Answer:</u></h2>

Jared and Pedro walked a total of <u>4.3 miles</u>

<h2><u>Step-by-step explanation:</u></h2>

The equation for distance is <u>speed = distance ÷ time.</u>
Rearrange the equation to make distance the subject:

<em>(multiply both sides by time)</em>

<em> </em><u>Distance = Speed × Time</u>

Convert your numbers into suitable units:

1 mile ÷ 15 = <u>0.06m/minute</u>

Finally, substitute the numbers into the equation and solve:

Distance = 0.06 × 65 = <u>4.3miles</u> (rounded to the nearest decimal place)

Answer:

a. $p = 2\pi r + 8r$

b. $r = \frac{p}{2\pi + 8}$

Step-by-step explanation:

a. Radius of semicircle (r) = r

Diameter of semicircle (d) = 2r

Length of rectangle (l) = 2*diameter of semicircle = 2*2r = 4r

Distance around the track (p) = circumference of circle + 2(l)

Note: the two semicircles of the track = 1 full circle

Circumference of full circle = πd = π*2r = 2πr

Distance around the track:

p = 2πr + 2(4r)

p = 2πr + 8r

b. Rewriting the formula to make radius, r, the subject of the formula in terms of distance around the track.

$p = 2\pi r + 8r$

Factor out r

$p = r(2\pi + 8)$

Divide both sides by (2π + 8)

$\frac{p}{2\pi + 8} = \frac{r(2\pi + 8)}{2\pi + 8}$

$\frac{p}{2\pi + 8} = r$

$r = \frac{p}{2\pi + 8}$
