so

360 degree make arc of length 62.8in

1 degree will make arc length 62.8/360 =0.17in

so

A swimming pool holds 480,000 liters of water. The pool has two drainage pipes. When the pool is completely full, the first pipe
sweet-ann [11.9K]
The answer is 96 min, here is why:

x / 240 + x / 160 = 1 
<span>2x + 3x = 480 </span>
<span>5x = 480 </span>
<span>x = 96 min

(</span><span>Drainage rate of first pipe = 480000/240 = 2000 l/min </span>
<span>Drainage rate of second tube = 480000/160 = 3000 l/min </span>
<span>Combined drainage rate = 5000 l/min </span>
<span>Time to drain = 480000/5000 = 96 min. )</span>

Graph the line with slope 1/2 passing through the point (5, - 1)
True [87]

Answer:

<u><em>The equation is y = (1/2)x + - 3.5</em></u>

Step-by-step explanation:

We look for an equation with the form y = mx + b, where m is the slope and b the y-intercept.

We're given the slope, (1/2) which we can use for m:

y = (1/2)x + b

We are told the line goes through (5,-1).  We need a value of b that will move the line to include this point.  Do that by substituting the values:

 x = 5, and y= -1

y = (1/2)x + b

-1 = (1/2)*5 + b

-1 = (2.5) + b

- 3.5 =   b

<u><em>The equation is y = (1/2)x + - 3.5</em></u>

See the attached image.
