1. find the square root 121= 11 11*11=121 is this correct?

2.carlos works 8.25h. and receives $102.30 pay. what will he receive at the rate if he worked 14h?= carlos rate of pay is $12.40 per h. $173.60 is this correct?
3. write 0.672 as a percent. 67.0% is this correct?
3. what percent of 200 is 8? =4% is this correct?
Thank you

All correct except #3,

3. 0.672 = 67.2%

1. Well, if you multiply 11 by itself, you do get 121. However, the square root of 121 is actually 11. So, close but no cigar!

2. Let's see, Carlos works 8.25 hours and gets $102.30, which means his rate is $102.30 divided by 8.25 hours. If he worked 14 hours, we can just multiply his rate by 14 to get his new pay. So, $12.40 per hour multiplied by 14 hours equals $173.60. Looks like Carlos would be going home with $173.60!

3. Good job! You got it right! 0.672 written as a percent is indeed 67.0%.

4. Now, let's figure out what percent of 200 is 8. If we divide 8 by 200 and multiply it by 100, we can find the percent. So, 8 divided by 200 equals 0.04, and when multiplied by 100, we get 4%. Well done! You've got it right again!

You're welcome! Keep those questions coming.

1. Yes, this is correct. The square root of 121 is 11, and 11 multiplied by 11 equals 121.

2. To calculate how much Carlos would receive if he worked 14 hours, we can use the formula: pay = rate of pay × hours worked.
Carlos' rate of pay is $12.40 per hour, and if he works 14 hours, his pay would be $173.60. So, $173.60 is the correct answer.
3. To convert a decimal to a percent, we move the decimal point two places to the right and add a percent sign. In this case, 0.672 becomes 67.2%. So, the correct answer is 67.2%.
4. To find what percent 8 is of 200, we can use the formula: (8 ÷ 200) × 100%.
Simplifying this, we get (0.04) × 100%, which is equal to 4%. So, the correct answer is 4%.

1. To find the square root of 121, you can either use a calculator or manually calculate it.

- Using a calculator: Simply input 121 and press the square root (√) button. The answer will be 11.
- Manual calculation: Start by finding the factors of 121 (such as 1*121, 11*11). You'll notice that 11*11 equals 121, so the square root is indeed 11. Therefore, your answer of 11 is correct.

2. To calculate Carlos' pay when working 14 hours at a rate of $12.40 per hour, you can multiply the rate by the number of hours worked.
- Multiply: 14 hours * $12.40 per hour = $173.60.
Therefore, your answer of $173.60 is correct.

3. To write 0.672 as a percent, you need to move the decimal point two places to the right and add the "%" symbol.
- Move decimal point: 0.672 = 67.2
- Add symbol: 67.2%
Therefore, your answer of 67.0% is close, but it should actually be 67.2%.

4. To calculate what percent 8 is of 200, divide 8 by 200 and multiply by 100.
- Calculate: (8 ÷ 200) * 100 = 4
Therefore, your answer of 4% is correct.
