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

A volleyball coach plans her daily practices to include 10 minutes of stretching, 2/3 of the entire practice scrimmaging, and the remaining practice time working on drills of specific skills. On Wednesday, the coach planned 100 minutes of stretching and scrimmaging. How long, in hours, is the entire practice?

Answers

Answer:

Time for the entire practice is 2.25 or 2 1/4 hours

Step-by-step explanation:

According to the question the volley ball coach daily plan practice includes stretching , scrimmaging and she use the remaining practice time working on drills of specific skills.

let the entire time required for practice = y minutes

Stretching consumes 10 minutes, mathematically

stretching = 10 minutes

scrimmaging = 2/3 × y

Drills of specific skills = y - (2/3 × y) - 10 = 1/3 y - 10 minutes

On Wednesday she had

stretching + scrimmaging = 100 minutes

we all know her stretching daily timing is 10 minutes and scrimmaging timing is 2/3 × y

Therefore,

10 + 2/3 y = 100

100 - 10 = 2/3 y

90 = 2/3 y

multiply both sides by 3

90 × 3 = 2/3 y × 3

270 = 2 y

y = 135 minutes

since the answer is suppose to be in hours

60 minutes = 1 hour

135 minutes = ?

135/60 = 2.25 hours or 2 1/4 hours

Since it is 100 minutes of stretching and scrimmaging, we can subtract the 10 minutes we know is stretching. 90 minutes is equal to 2/3 of the practice then. Divide by 2 and multiply by 3 to get the entire time of the practice or 135 minutes. However, you asked for it in hours, so we can subtract 120 minutes because this is 2 hours. 15 minutes is 1/4 of an hour. So practice took 2&1/4 hours. Hope that helps.

Solve for y:-

10 + y = 28

Thanks!

Answers

To solve for y we have to use the INVERSE OPERATION of addition which is subtraction. Lets do it:-

10 + y = 28
y = ?
28 - 10 = y
28 - 10 = 18
y = 18

CHECK OUR WORK:-

10 + y = 28
y = 18
10 + 18 = ?
10 + 18 = 28
We were RIGHT!!!!

So, y = 18.

Hope I helped ya!! xD

Use the inverse operation to solve for x.

10 + y = 28

$10 + y = 28$

$y = 28 - 10$

Answer: $y = 18$

in a survey, 27% of people chose salads over a meat dish. In all, 81 people chose salads. How many people were in the survey?

Answers

Number of people that chose salad = 81
Percentage of people that chose salad over meat dish = 27%
Let us assume the number of people on the survey = x
Then
27% * x = 81
(27/100) * x = 81
27x = 81 * 100
27x = 8100
x = 8100/27
= 300
So a total of 300 people participated in the survey.I hope the procedure is clear enough for you to understand. Based on this method you can always solve similar types of problems without requiring any kind of help from outside.

Answer:

300

Step-by-step explanation:

27 is to 100 as 81 is to 300
