The Pool Fun Company has learned​ that, by pricing a newly released Fun Noodle at $4, sales will reach 8000 Fun Noodles per day during the summer. Raising the price to $5 will cause the sales to fall to 6000 Fun Noodles per day. Assume that the relationship between sales​ price, x, and number of Fun Noodles​ sold, ​ y, is linear. Write an equation in​ slope-intercept form describing this relationship. Use ordered pairs of the form​ (sales price, number​ sold).

type your answer in slope intercept
b. predict the daily sales of Fun Noodles if the price is $4.50​

Answer 1
Answer:

Answer: PART A:

The generic equation of the line is:

y-yo = m (x-xo)

First we look for the slope of the line:

m = (y2-y1) / (x2-x1)

m = ((5000) - (6000)) / (4-3)

m = -1000

Then, we substitute any point in the generic equation:

(xo, yo) = (4, 5000)

Substituting:

y-5000 = (- 1000) (x-4)

Rewriting:

y = -1000x + 4000 + 5000

y = -1000x + 9000

The equation is:

y = -1000x + 9000

PART B:

For the price of 3.50 we have:

y = -1000 * (3.5) +9000

y = 5500

What is the area of rectangle PQRS?

Answers

The length of PQ = 3 + 4.5 + 2 = 9.5 inches.

The area is Length times width:

4.5 x 9.5 = 42.75 square inches.


The answer is D.

Add 2+4.5+2 and that is 9.5 PQ=9.5

multiply 4.5*9.5

that is 42.75 so the answer is D

Answers

3t<-15 solve for t

divide both sides by 3
3t/3 < -15/3

Simplify
t < -5

Anser is a. t<-5
If 3t < -15 all you need to do is divide by 3 on both sides, 

t < -5

The yearbook club had a meeting. The meeting had 15 people, which is three-fifths of the club. How many people are in the club?

Answers

25. 
For me, I just did 15 divided by 3, which equals to 5. So.. You do 5 x 5 to find out how many people there are in the club in total. 

Final answer:

The question is about finding the total number of people in the yearbook club given that 15 people represent three-fifths of the total. By using a proportion, we find that the yearbook club has 25 people.

Explanation:

This is a proportional relationship problem in mathematics. You are given that 15 people represent three-fifths (or 3/5) of the total number of people in the yearbook club. To find the total number of people in the club, you set up the proportion: 15 is to 3 and X is to 5.

Then, cross multiply and solve the equation for X. 3*X = 15*5, therefore X = 75/3 = 25. So, there are 25 people in the yearbook club.

Radius of a circle with diameter 240mm

Answers

The radius of the circle with the given diameter would be = 120mm.

What is the diameter of the circle?

The diameter of the circle is defined as a line segment that passes through the center of a circle and has two endpoints at the circumference.

The radius is defined as the distance from the centre of a circle to any point on the boundary. The radius:

= Diameter/2

Therefore, the radius of the circle = 240/2 = 120mm
