25.) Suppose the linear cost function C(x) = 6x gives the cost for buying x items. If the items are sold in packages of 10, and no one can buy more than 5 packages, then the RANGE of the function C is

B) [5, 10]
C) {0, 6, 12, 18, 24, 30}
D) {0, 60, 120, 180, 240, 300}
Answer:
24) D
25) D
Step-by-step explanation:
24) D
We want to find the equation of a line (in slope-intercept form) that passes through (2, -2) and is perpendicular to [tex]y=\frac{2}{5}x+2[/tex].
First, let's find the slope of our new line.
Remember that perpendicular slopes are negative reciprocals of each other.
Therefore, to find the slope of our new line, we will flip our old slope and add a negative.
Therefore, the slope of our new line is -5/2.
Now, we can use the point-slope form:
[tex]y-y_1=m(x-x_1)[/tex]
Where m is the slope and (x₁, y₁) is a point.
So, let's substitute -5/2 for our slope and (2, -2) for our point (x₁, y₁). This yields:
[tex]y-(-2)=-\frac{5}{2}(x-2)[/tex]
Simplify:
[tex]y+2=-\frac{5}{2}(x-2)[/tex]
Let's convert this to slope-intercept form. Distribute the right:
[tex]y+2=-\frac{5}{2}x+5[/tex]
Subtract 2 from both sides. So, our equation is:
[tex]y=-\frac{5}{2}x+3[/tex]
Our answer is D.
25)
We know that the cost for buying x items is given by the function:
[tex]C(x)=6x[/tex]
We also know that the items are sold in packages of 10 only. And no one can buy more than 5 packages. In other words, we can buy 0, 1, 2, 3, 4, or 5 packages.
So, let's see how much it will be if we buy 0 packages. This will just be:
[tex]C(0)=6(0)=\$0[/tex]
If we buy 1 package, there will be 10 items in them. So:
[tex]C(10)=6(10)=\$60[/tex]
If we do this for 2 packages (20 items), 3 packages (30 items), and so on, we will get:
[tex]C(20)=6(20)=\$120\\C(30)=6(30)=\$180\\C(40)=6(40)=\$240\\C(50)=6(50)=\$300[/tex]
So, our range is:
[tex]\{0, 60, 120, 180, 240, 300\}[/tex]
The correct answer is D.
And we're done!
How do I find the percentile of someone with a certain number of things from a dot plot data set?
Answer:
percentile rank of x =
number of values before x 100
--------------------------------------------------- x ----------
number of total values on the dot plot 1
Step-by-step explanation:
you divide the number of values before x over the number of total values on the dot plot, and divide the quotient by 100 to get your percentile.
Maureen, Frank, Tashia, Zane, Eric, and Wesley are addressing envelopes for volunteer work at a local charity. They were given ¾ of an entire mailing to address to be evenly divided among six of them. What fraction of the entire mailing does each person address?
Answer:
The fraction of the entire mail each person address = 1/8
Step-by-step explanation:
Given that:
number of people addressing envelopes = 6
If they gave out 3/4 of an entire mailing address.
Then, the amount of mailing not addressed is:
= 1 - 3/4
= [tex]\dfrac{4-3}{4}[/tex]
= 1/4
If 6 people shared 3/4 of an entire mailing to address evenly.
Then: each person gets:
[tex]=\dfrac{3}{4} \div 6[/tex]
[tex]=\dfrac{3}{4} \times \dfrac{1}{ 6}[/tex]
= 1/8
The fraction of the entire mail each person address = 1/8

What is m∠TVU?
m∠TVU = __°
[tex]4x + 3 = 3x + 12[/tex]
Both sides minus 3
[tex]4x = 3x + 12 - 3[/tex]
[tex]4x = 3x + 9[/tex]
Both sides minus 3x
[tex]4x - 3x = 9[/tex]
[tex]x = 9[/tex]
So :
TVU = 3(9)+12 ----¢ TVU = 27 + 12
TVU = 39°

SAM'S
Store
Stand kve seat
$1300
$1400
$1600
Sols and two chairs
Safa, love seat, and one chair
Your answer
Answer:
1. The system of equations is given as follows;
S + L = $1,300................(1)
S + 2·C = $1,400............(2)
S + L + C = $1,600.........(3)
Where;
S = The cost of a sofa
L = The cost of a love sea
C = The cost of a single chair
2. The cost of a love sea, L is $500
Step-by-step explanation:
1. The given information are;
The price of sofa and love sea = $1,300
The price of sofa and two chairs = $1,400
The price of sofa, love sea, and one chair = $1,600
Let the cost of a sofa = S
Let the cost of a love sea = L
Let the cost of a chair = C
Therefore, we have;
S + L = $1,300................(1)
S + 2·C = $1,400............(2)
S + L + C = $1,600.........(3)
2. From equation (1), we have;
L = $1,300 - S
Similarly, from equation (2),we have;
C = ($1,400 - S)/2
Substituting the values of L and C in equation (3), we have;
S + $1,300 - S + ($1,400 - S)/2 = $1,600
Which gives;
($1,400 - S)/2 = $1,600 - $1,300 = $300
$1,400 - S = 2 × $300 = $600
$1,400 = $600 + S
$600 + S = $1,400
S = $1,400 - $600 = $800
S = $800
The cost of a love seat, L, is given from the relation L = $1,300 - S, above, which gives;
L = $1,300 - $800 = $500
The cost of a love sea, L is $500 .

60 percent of what number is 30?
Answer:
the answer willl be 50%
The 60 percent of 50 equals 30.
To find what number is 60 percent of 30, you can set up the following equation:
0.60 * x = 30
Here, 'x' represents the unknown number that is 60 percent of 30. To solve for 'x,' divide both sides of the equation by 0.60:
x = 30 / 0.60
Now, perform the division:
x = 50
Therefore, 60 percent of 30 is 50. In other words, 50 is the number you are looking for, which is 60 percent of 30. You can verify this by calculating 60 percent of 50:
0.60 * 50 = 30
As expected, 60 percent of 50 equals 30.

Answer:
1.) 12 hours 2.) She made a multiplying error in the table.
Step-by-step explanation:
1.)
First, let's find the slope of this equation:
m = 135 - 81 / 5 - 3
m = 54/2
m = 27
Therefore, the equation should be y = 27x.
Now we substitute 324 for y and solve for x:
324 = 27x
12 = x (Divided 27 on both sides.)
Therefore, someone would have to work 12 hours in order to earn $324.
2.)
For this problem, it appears Amanda has found the correct equation for her recipe. When taking a look at the table, however, it seems as though she has made a multiplying error.

A toy box contains eight green balls and four purple balls. Suppose you choose a ball at random and then replace it by putting it back in the toy box. You then choose a second ball. What is the probability that you have selected a green ball and then a purple ball?
Option A: 2/9
Option B: 1/2
Option C: 1/3
Option D: 2/3
Answer: C. [tex]\dfrac{1}{3}[/tex]
Step-by-step explanation:
Given: Box contains 8 green balls and 4 purple balls.
Total balls = 8+4 = 12
event 1 = first picking green ball
event 2 = second picking purple balls.
As first ball was replaced, that means both events are independent.
Probability that you have selected a green ball and then a purple ball = P(purple ball )
Formula for probability = [tex]\dfrac{\text{favorable outcomes}}{\text{total outcomes}}[/tex]
Probability of selecting a purple ball (second pick)= [tex]\dfrac{4}{12}[/tex]
[tex]=\dfrac{1}{3}[/tex]
The required probability [tex]=\dfrac{1}{3}[/tex], so C is correct option.

a line passing through the points (2. -6) and (4, -16)
Answer:
a line passing through the points (2, -6) and (4, -16)
Step-by-step explanation:
y=-5x+4
you plug in the x value and put the y value on the left side of the equation
for example
-6 = -5(2) + 4
then solve to see if it works
-5(2) = -10 + 4 = -6
(2, -6) works
-16 = -5(4) +4
-5(4) = -20
-20 + 4 = -16
(4, -16) works
