Han spent 75 minutes practicing the piano over the weekend. For each question, explain or show your reasoning. A. Priya practiced the violin for 152% as much time as Han practiced the piano. How long did she practice? B. Tyler practiced the clarinet for 64% as much time as Han practiced the piano. How long did he practice?

a. 114 minutes

b. 48 minutes

Step-by-step explanation:

Given that

Time spent over the piano is 75 minutes

a. if Priya practice violin for 152% as Han Practiced for piano

So the minutes she practice in Violin is

= 75 minutes × 152%

= 114 minutes

Likewise

b. If Tyler practiced for clarinet for 64% as Han Practiced for piano

So the minutes he practice in Clarinet is

= 75 minutes × 64%

= 48 minutes

The same is to be considered

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
