Han spent 75 minutes practicing the piano over the weekend. 1. Priya practiced the violin for 152% as much time as Han practiced the piano. How long did she practice? Type the answer in the box below. minutes 3. Tyler practiced the clarinet for 64% as much time as Han practiced the piano. How long did he practice?

Priya practiced for 189 minutes

Tyler practiced for 123 minutes

Step-by-step explanation:

Han spent 75 minutes practicing the piano over the weekend

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

Priya practiced for 189 minutes

2.

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

Tyler practiced for 123 minutes

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
