Han has Spent 75 minutes practicing the piano over the weekend priya practice the violin for 152% as much time as hand practicin
madam [21]

Answer: 114 minutes

Step-by-step explanation:

From the question, we are informed that Han has Spent 75 minutes practicing the piano over the weekend while Priya practice the violin for 152% as much time as Han used in practicing the piano.

Therefore, the number of minutes used in practicing by Priya would be gotten by multiplying 152% by 75 minutes. This would be:

= 152% × 75 minutes.

= 152/100 × 75minutes

= 1.52 × 75 minutes

= 114 minutes

Help please !!! ❗️❗️❗️❗️❗️❗️
Crazy boy [7]

Step-by-step explanation:

1. f(x) = 12x + 1

f(-2) = 12(-2) + 1 = -23

f(0) = 12(0) + 1 = 1

f(3) = 12(3) + 1 = 37

2. p(x) = -8x - 2

p(-2) = -8(-2) - 2 = 14

p(0) = -8(0) - 2 = -2

p(3) = -8(3) - 2 = -26

3. m(x) = -6.5x

m(-2) = -6.5(-2) = 13

m(0) = -6.5(0) = 0

m(3) = -6.5(3) = -19.5

4. s(x) = ⅖x + 3

s(-2) = ⅖(-2) + 3 = -⅘ + 3 = 11/5

s(0) = ⅖(0) + 3 = 3

s(3) = ⅖(3) + 3 = 6/5 + 3 = 21/5

5. h(x) = ¾x - 6

h(-2) = ¾(-2) - 6 = -6/4 - 6 = -30/4

h(0) = ¾(0) - 6 = -6

h(3) = ¾(3) - 6 = 9/4 - 6 = -15/4
