prisoha [69]

Answer: Priya practiced for <u>189 minutes </u>

Tyler practiced for <u>123 minutes </u>

-------------------------------------------------------------------------------------------------------------

The Explanation:  Now, Han spent 75 minutes practicing the piano over the weekend

Then, Priya practiced the violin for 152% as much time as Han practiced the piano.

Priya = 152% of 75 minutes + 75 minutes

= 152/100 × 75 + 75

= 1.52 × 75 + 75

= 114 + 75

= 189 minutes

Finally, Priya practiced for <u>189 minutes</u>

-------------------------------------------------------------------------------------------------------------

Tyler practiced the clarinet for 64% as much time as Han practiced the piano.

Tyler = 64% of 75 minutes + 75 minutes

= 64/100 × 75 minutes + 75 minutes

= 64 / 100 × 75 + 75

= 0.64 × 75 + 75

= 48 + 75

= 123 minutes

Lastly, Tyler practiced for <u>123 minutes</u>

Answer:

Step-by-step explanation:

Calculus....finally something FUN to answer!

This is integration, but here you have the area under the curve, you just don't have the upper bound. Setting that problem up looks like this:

28=\int\limits^b_1 {7x} \, dx  and using the First Fundamental Theorem of Calculus, that will integrate to look like this:

28=\frac{7x^2}{2} from 1 to b and applying the FTC:

28=\frac{7b^2}{2}-\frac{7}{2}  Multiplying everything by 2 to get rid of the denominators gives you:

56=7b^2-7\\\\56=7(b^2-1)\\8=b^2-1\\9=b^2\\b=3
