HELP PLEASE!!! SHOW WORK!! A professional pianist spends an average of 45 hours practicing the piano in a three-week period. Usi
kicyunya [14]

Answer:

An average of about 450 hours; You could say something along the lines of "If the pianist who practices an average of 45 hours per week practices everyday for three months, they would play for approximately 450 hours total."

Step-by-step explanation:

We could write an equation to make it simpler to figure out, making the number of hours after three months = n, 4 = weeks in a month, 3 = the number of months, and 45 = the number of hours after a week. As an equation, it would look like:

45 * 3 * 4 = n

We know 3 *4 is 12, so the equation becomes 45 * 12 = n.

45 * 12 = 540, therefore the pianist practices an average of approximately 540 hours over a three-month period of time.

Pls answer 18 20 and 22 show your work
Svetlanka [38]

Answer:

18- 300

20- 1,500

22- 300

Step-by-step explanation:

You can easily find the answer like this:

18. Multiply 60 and 100 together. The hundred is from 100%. After that, divide it by 20 because of the percent. After doing this, you should get 300.

20. 360*100=36,000 36,000/24= 1,500

22. 9*100=900 900/3=300


I hope this is what you were looking for. If you need more out of this, ask me to answer it again. :)
