10 The cost to rent the cabin is $125 per night, plus a $50
non-refundable cleaning fee. Which equation would find the
total cost C of staying at the cabin for n nights?
A C = 125n + 50
B C = 50n + 125
с
n = 125C + 50
D 125
50C +n
Answer:
C=125n+50
Step-by-step explanation:
each night you stay represents "n" so if you stayed 3 nights(n)
you would multiple 125x3= 375
plus the $50 non refundable charge
Which expression is equivalent to 8x- 2y - + x + x
A.4x
B.8x
C.6x - 2y
D.10x - 2y
Answer:
C
Step-by-step explanation:
Subtract like-terms. -2y is the only variable that has a y and is therefore unaffected. 8x - x - x = 6x.

so basically when we write all three of the expressions in one fraction we get the same answer for all three multiplications.
a. (3/4)*7=(3*7)/4
b. 7*(3/4)=(7*3)/4
c. 3*(7/4)=(3*7)/4
when we change the place of the values that are being multiplied the value of the multiplication does not change, that's why they will be have the same answer and when we multiply all the operations, we get the same value as the answer.

NK Karate Club offers two different fees for their karate classes. Club members are charged a one-time membership fee of $32 and pay $4 per class. Non-members pay $8 per class. Let y represent the number of karate classes attended.
a. Write an expression to represent the cost for a non-member to attend y classes.
b. Write an expression to represent the cost for a member to attend y classes.
c. Set the two expressions equal to each other and solve the equation to determine how many classes result in the same cost for a member and non-member.
Answer:
a) x = 8y
b) x = 32 + 4y
c) 8y = 32 + 4y
Step-by-step explanation:
-4y -4y
8y = 32 + 4y
÷4 ÷4
4y = 32
y = 32
The expression represents the cost for a non-member to attend y classes is x=8y.
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
Given that, Club members are charged a one-time membership fee of $32 and pay $4 per class. Non-members pay $8 per class.
Let y represent the number of karate classes attended.
a) The cost for a non-member to attend y classes is
Non-members pay $8 per class.
So, the expression is 8y
b) The cost for a member to attend y classes is
Club members are charged a one-time membership fee of $32 and pay $4 per class.
Now, the expression is 32+4y
c) Set the two expressions equal to each other, that is
8y =32 + 4y
8y-4y=32
4y=32
y=8
Therefore, the expression represents the cost for a non-member to attend y classes is x=8y.

If N is the plane of symmetry, click on the graphic to find the figure that is symmetrical with respect to plane N.
Answer:
thrid one looks right
Step-by-step explanation:
Answer:
The 4th cone
Step-by-step explanation:
Hello, the answer to your question is the 4th cone; the cone with its bottom half facing skyward. If you are familiar with plane symmetry, this question is fairly simple. Since the topmost cone has its bottom half facing downward, it would only be logical to choose the cone that forms mirror halves (superimpose) when paired.

Step-by-step explanation:
imagine a right triangle in the middle,
base: 16 ÷ 2 = 8 cm, height: 10 cm, side: s
10² + 8² = s²
=> s = √(10² + 8²)

Answer:
7. [tex]c = 15.81[/tex]
8. [tex]b = 16[/tex]
Step-by-step explanation:
Required
Determine the third sides
(7): We have
[tex]b = 5[/tex]
[tex]a = 15[/tex]
[tex]c=??[/tex]
To find c, we make use of Pythagoras theorem
[tex]c^2 = a^2 + b^2[/tex]
[tex]c^2 = 5^2 + 15^2[/tex]
[tex]c^2 = 250[/tex]
[tex]c = \sqrt{250[/tex]
[tex]c = 15.81[/tex]
(8): We have
[tex]c = 20[/tex]
[tex]a = 12[/tex]
[tex]b = ??[/tex]
To find c, we make use of Pythagoras theorem
[tex]c^2 = a^2 + b^2[/tex]
[tex]20^2 = 12^2 + b^2[/tex]
[tex]400 = 144 + b^2[/tex]
[tex]b^2 = 400 - 144[/tex]
[tex]b^2 = 256[/tex]
[tex]b = \sqrt{256[/tex]

LifeCharge Batteries claims that their batteries last an average of 210 hours when used in a hand held gaming system, with a standard deviation of about 9 hours. An independent quality control company took a sample of 34 batteries, and used the same hand held gaming system that LifeCharge used to record the time the batteries lasted.
1. Assuming the claim is true, what is the probability that the value of the sample mean is greater than 251.7 hours.
2. The sample mean was found to be 251.7, what does this say about the claim?
A. The sample mean is quite far off from the mean claimed, casting doubt on the current mean.
B. The sample mean is sufficiently close to the mean claimed, supporting the current mean.
C. The sample mean found does not truly support nor cast doubt on the current mean.
Answer:
The answer is "0.0023 and Choice a"
Step-by-step explanation:
In point a:
The central limit theorem:
[tex]\mu_{X}= 250\\\\\sigma_{X}=\frac{\sigma}{\sqrt{n}}=\frac{6}{\sqrt{100}} =0.6\\\\P(\bar{X}>251.7)\\\\=P(z>\frac{251.70-250}{0.6})\\\\=P(z>2.83)\\\\=1-0.9977\\\\=0.0023[/tex]
In point b:
The chance is lower than 0.05. This means that it is very rare to see the average sample above 251.8 if the argument is valid, that is why the means of the sample is far away from the common claimed and casts doubt on the actual mean.

y = -3x + }
O y = -fx +
B y = -3.x + 3
Answer:
A. y = -⅓x + 3
Step-by-step explanation:
Find the equation of the graph bin slope-intercept form, y = mx + b. Where,
m = slope = ∆y/∆x
Using two points on the line, (0, 3) and (3, 2),
Slope (m) = (2 - 3)/(3 - 0) = -1/3
m = -⅓
b = y-intercept = 3 (the y-coordinate of the point where the line crosses the y-axis)
✅To write the equation, substitute m = -⅓ and b = 3 into y = mx + b
Thus:
y = -⅓x + 3
Find the equation for the line shown on the right.

The line graph
First, consider the following points on the graph.
[tex](x_1,y_1) = (8,0)[/tex]
[tex](x_2,y_2) = (8,8)[/tex]
First, calculate the slope.
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{8-0}{8-8}[/tex]
[tex]m = \frac{8}{0}[/tex]
[tex]m =[/tex] undefined
Since, the slope is undefined; we simply consider only the value of x.
The line equation is:
