Answer:

Step-by-step explanation:

For test A, the unit rate is 30 words per minute divided by 4 minutes, or 7.5 words per minute.

Unit rate = 78 words/15 minutes = 5.2 words per minute for test B.

The unit rate for test C is 99 words/22 minutes, or 4.5 words per minute.

Machine A prints 16 pages more than Machine B in every minute. Machine A and Machine B print a total of 608 pages in 4 minutes.

1) So the ratio of Machine A to B is x + 16 : x (x being the paper printed in machine b).

2) This is in 4 minutes so every minute it will be 152.

2) So x + 16 + x = 152, or 2x + 16 = 152.

3) So to find x, we can subtract 16 from both sides. 2x = 136

4) Now we just divide both sides by 2 to get x = 68.

5) So machine A will be 68 + 16 = 84.

= 84

11111nata11111 [884]

Answer:

The answer is

<h2>660.5 square feet</h2>

Step-by-step explanation:

Area of a circle = πr²

where r is the radius

From the question

diameter = 29 feet

To find the radius given the diameter we use the formula

$radius = \frac{diameter}{2} \\ radius = \frac{29}{2} \\ = 14.5 \: \: feet$

So the area of the circle is

$A = {14.5}^{2} \pi \\ = 210.25\pi \\ = 660.519...$

We have the final answer as

<h3>660.5 square feet</h3>

Hope this helps you
