A 18,000 gallon swimming pool contains 7000 gallons of water when a hose is placed in the pool and begins adding water at a rate

of 1100 gallons per hour
Use the Segment tool to plot a graph representing the volume of water in the pool over time from when the hose is placed in the pool until the pool is full.

Answer:

(0, 7000); (10, 18000)

Step-by-step explanation:

Lets first start by breaking the problem down

Breaking the problem down

We add 1100 gallons for every hour

The pool already contains 7000 gallons

Our goal is 18000 gallons.

Make an equation

y = mx + b

In this case we're lucky as all of these are given.

Our slope of m is how many of gallons we gain for every x value (hours)

So plugging it in we can rewrite it so far as

y = 1100x + b

Now our b value is our y-intercept which is what we start with at x = 0 which is also where the value touches our y-axis.

In this case at 0 hours passed we have 7000 gallons thus 7000 is our b.

We can plug it in and rewrite as follows

y = 1100x + 7000

Now what we want to solve for is our y so we plug 18,000 in for y and solve by getting x alone

        y = 1100x + 7000

18000 = 1100x + 7000

-7000               -7000

11000 = 1100x

Divide both sides by 1100 and you have your hours until its full

10 = x

So at 10 hours the 18000 gallon pool will be full,

As such we can determine our second point as (10, 18000)

Now because we know our y-intercept we can use that to find the other point.

The line intercepts the y axis (0, y) at 7000, and as such our point is

(0, 7000)

Putting them together we have point A and point B solved

A(0, 7000) B(10, 18000)

Note the points are (x value, y value)

Hope this helps, if you have any more trouble leave a comment and I'll help you further

Y=-1/2x +7

Answer:

B; (2,-4)

Step-by-step explanation:

The general equation of a straight line is;

y = mx + b

where m is the slope and b is the y-intercept

So from the question, when we look at the given equation, its slope is -1/2

mathematically, when two lines are perpendicular, the product of their slopes is -1

thus;

m1 * m2 = -1

m2 * -1/2 = -1

-m2 = -2

m2 = 2

The general equation form is;

y-y1 = m(x-x1)

where (x1,y1) = (4,0)

y-0 = 2(x-4)

y = 2x - 8

So, now we look at the point that will work for this equation

For the line that will work, if we substitute its x-value, we get the y-value

Let us take a look at option B

y = 2(2) -8 = 4-8 = -4

we can see that (2,-4) works

The Harrison family paid $14,400 in rent last year. The landlord has decided to raise rent 2.5% each year. How much will the Har
skelet666 [1.2K]

Answer: $16,200

Step-by-step explanation:

14,400 rent.

Raise of 2.5% (0.025)/year.

5 years.

Take the rent (14,400) and add 2.5% (0.025) of it (14400) for five (5) years.

14400+0.025(14400)(5)

14400+1800\\=16200

Complete question :

The data below represents the number of customers at each Slurpee Sam's Spaghetti Shop. 24, 25, 29, 30, 31, 31, 32, 34, 34. Which box plot correctly summarizes the data?

Answer:

B

Step-by-step explanation:

BOX plots provide information about :

Minimum, Lower quartile, Median, Upper quartile and maximum value of a dataset.

Given the dataset :

24, 25, 29, 30, 31, 31, 32, 34, 34

Minimum value = 24 (Lowest value in the dataset)

First quartile (Q1) = 1/4(n+1)th term

Q1 = 1/4 * 10 = 10/4 = 2.5th term = (25+29)/2 = 27

Second quartile ; median (Q2) = 1/2(n+1)th term

Q2 = 1/2(n+1)th term = 1/2(10) = 5th = 31

Third quartile (Q3) = 3/4(n+1)th term

Q3 = 3/4(n+1)th term = 3/4(10) = 30/4 = 7.5th term = (7th +8th) term = (32 + 34) / 2 = 66/2 = 33

Maximum value = 34 (Highest value in the dataset)

First dot = minimum value

Last dot = maximum value

First line of box = QI

mid line = median

End line of box = Q3
