Hi, do you know how to find percentages of numbers?

2. iwillrektyou

Okay, so if you were to find 25% of 200, you do 200 * 0.25 = 50

3. anonymous

Ok

4. iwillrektyou

For this, you do the same thing. Do you want me to show you the first one?

5. anonymous

Yes plzz

6. iwillrektyou

Ok, 2/5 is also 40%, written in decimal form as 0.4 0.4 * 40 = 16

7. anonymous

So 0.4 * 75 would be 30

8. iwillrektyou

Yes. Great job! Now just one more. Doing it with 100 is very easy, because a percent is out of 100.

9. anonymous

So it would be 40

10. iwillrektyou

Yes. Great job! Those are the answers.

12. iwillrektyou

13. anonymous

Ok

14. anonymous

Can Yhuu help with simplifying

15. iwillrektyou

Sure, I will try.

16. anonymous

Ok simplify the expression ( 20-14) cubed divided by 12

17. anonymous

Nvm I got thx though bt I have another queation instead will Yhuu help?

18. iwillrektyou

Ok. So, based on order of operations, you first solve the parenthesis: (20 - 14)^3 divided by 12 --> (6)^3 divided by 12

Suppose you make \$12 an hour as a lifeguard at the community pool during the summer let H represent the number of hours you work in a week write an expression that represents the amount of money you earn in a week and evaluated for h equals 15

20. iwillrektyou

Hmm... I think you are supposed to find the number of hours in a week in order to solve. The original equation is: 12h. You just have to substitute 15 for h and solve.

21. anonymous

Ok thx got it

22. iwillrektyou

Np! I will try to attend to any other stuff you tag me to, and I will try to help you as much as possible. Hopefully I'm not in school or extracurricular activities when that happens. :)
