PLEASEEE HELPP The water usage at a car wash is modeled by the equation W(x) = 3x3 + 4x2 − 18x + 4, where W is the amount of water in cubic feet and x is the number of hours the car wash is open. The owners of the car wash want to cut back their water usage during a drought and decide to close the car wash early two days a week. The amount of decrease in water used is modeled by D(x) = x3 + 2x2 + 15, where D is the amount of water in cubic feet and x is time in hours. Write a function, C(x), to model the water used by the car wash on a shorter day. C(x) = 2x3 + 2x2 − 18x − 11 C(x) = 3x3 + 2x2 − 18x + 11 C(x) = 3x3 + 2x2 − 18x − 11C(x) = 2x3 + 2x2 − 18x + 11

Jenny's great grandmother is 90 years old. Jenny is 12 years old, what percent of Jenny's great-grandmother's age is Jenny's age? Needs to be EXACT percent no decimal.

Answers

The required percentage of Jenny's great-grandmother age is Jenny's age is 13%.

What is the percentage?

The percentage is defined as a ratio expressed as a fraction of 100.

For example, If Misha obtained a score of 67% on her exam, that corresponds to 67 out of 100. It is expressed as 67/100 in fractional form and as 67:100 in ratio form.

Jenny's great-grandmother is 90 years old and Jenny is 12 years old.

To calculate the percentage of Jenny's age compared to her great-grandmother's age, you can divide Jenny's age by her great-grandmother's age and then multiply by 100.

So, (12/90) × 100 = 13.33%.

However, the answer should be in exact percent with no decimal, so the answer is 13%.

Answers

$\sf(3)/(5)(3y+15)$

Distribute 3/5:

$\sf(3)/(5)*3\rightarrow(3*3)/(5)\rightarrow(9)/(5)$

$\sf(3)/(5)*15\rightarrow(3*15)/(5)\rightarrow(45)/(5)\rightarrow9$

So we have:

$\boxed{\sf(9)/(5)y+9}$
