Since the workouts are normally on hour scale, thus the first comparison of $9.00 per hour of childcare is more appropriate here.

<h2>Given that:</h2>
  • Gym A charges $9.00 per hour of childcare.
  • Gym B charges $0.75 per 5 minutes of childcare

<h2>How to find which scale is appropriate when?</h2>

Firstly try to find what is the usual scale used for that work.

The usual scale used for given specified work is mostly the appropriate scale.

For Gym case, people are not coming and going in minutes scale, but they count in hours and will be able to comprehend the hour scale better.

Both Gym although offer same price (since $0.75 per minute is equal to $9.00 per hour), but the cost Gym A specifies is more easy to understand for normal public, thus it is more appropriate scale.

Factor completely 4x4 − 24x3 + 36x2.
ipn [44]

The previous answer from another person got deleted, so I'm here to put it back in my own words.

(Edit: The answer is A)

First of all, you can take 4 out of each, so simplify everything by 4.

4(x^4 - 6x^3 + 9x^2)

Next, you can see that you're able to take out x^2

4x^2(x^2 - 6x + 9)

You can see that both x^2 and 9 are perfect squares, meaning you can crunch them together like this

(x+3)^2 or (x-3)^2

Of course, only one would work, and as fate has it, (x-3)^ produces x^2 - 6x + 9

This would turn the now factored equation into :

4x^2(x-3)^2 or 4x^2(x-3)(x-3), this means the answer is A

Charlie reads quickly . He reads 1and3/7 pages every 2/3 minutes.How many pages does he read pre minute?
SVETLANKA909090 [29]
Hello there!

First, we need to admit that math is a hard subject. So, how do we handle hard stuff? We find an easy way. Right?

Well same goes here. They give the fractions to drive us crazy. Let's find the easiest way...

The easiest way is to turn them into decimals.
1 3/7 = 1.42 which is the amount of pages he reads
2/3 = 0.67 minute.

The are asking us how many pages does he reads per minute.

So we gonna say:
Charlie reads 1.42 pages ......> 0.67
Charlie reads x pages.............> 1minute

Cross multiply

0.67 * x = 1 * 1.42
0.67x = 1.42
x = 1.42/0.67
x = 2.11

So, Charlie reads 2.11 pages in 1 minute.


I hope this helps. Please let me know if you have questions about the answer.

Thanks!
