r: radius length
6. [tex]Perimeter=\frac{1}{2}\pi d + d= \frac{1}{2} \pi *18+18=9\pi +18 = 46.26cm[/tex]

Answer:
the last graph
Step-by-step explanation:
from what I can read of the question, it is asking for a decreasing pattern. If it is as the input increases, the only graph with the output decreasing is the last as it has a negative slope and is thus inversely related.
1 and 3 are positive slopes, and 2 does not have a trend line.
What is the solution to this inequality?
−4x − 8 > −20
Question 7 options:
x > −3
x < −3
x > 3
x <3
Answers
Answer:
[tex]\boxed{\sf{D. \quad x < 3}}[/tex]Step-by-step explanation:
It is necessary to isolate the term of x from one side of an inequality to find its solution.
-4x-8>-20First, add by 8 from both sides.
[tex]\sf{-4x-8+8 > -20+8}[/tex]
Solve.
-20+8=-12
Rewrite the problem down.
[tex]\sf{-4x > -12}[/tex]
Multiply by -1 from both sides.
(-4x)(-1)<(-12)(-1)
Solve.
Multiply the numbers from left to right.
(-12)(-1)=12
4x<12
Divide by 4 from both sides.
4x/4<12/4
Solve.
Divide the numbers from left to right.
12/4=3
x<3
Therefore, the correct answer is D. x<3 (last option).I hope this helps you! Let me know if my answer is wrong or not.

The only reason these two equations are correct, is because on the number line it shows: Any negative number further to the right than the last negative number is greater than that number.

PLEASE HELP Jax is surveying the number of children in restaurants. One restaurant has 7 children and a total of 42 customers. The next restaurant has 60 customers. Based on his survey, how many can he predict will be children?
A. 25
B. 10
C. 360
D. 5
Answers
Answer:
B.10
Step-by-step explanation:
42÷7=1. 1 child for every 6 customer. 60÷6= 10
Answer:
B
Step-by-step explanation:
If the first restaurant had 7 children within 42 customers, then we can divide 42 by 7 to get 6, which means 1 in 6 customers are children. If we apply this to the next restaurant, we will divide 60 by 6 to get 10.
This means there are 10 children in the second restaurant, so the answer is B.
Dale polled the 2 fastest swimmers on the swim team.
Is this sample of the swimmers on the swim team likely to be representative?
Answer as Yes or No
Answers
Reason:
Dale is biased toward the two fastest people in the group, but is leaving out the rest of the swimmers who may not be so fast. The people left out may be very distant from the top two swimmers. Therefore, Dale has not picked a representative sample.
As an example with numbers, let's say we had these average speeds in mph: {1, 2, 3, 4, 20, 30}. Of course these are just hypothetical examples and not based on actual realistic speeds; however, the example should still suffice.
That data set shows the average is closer to 2 and 3 than it is to 20 and 30. Dale polling the fastest people greatly skews the mean larger than it should be.
To get a better more representative sample, Dale should randomly pick 2 people regardless if they are the top two swimmers or not. He can pick the names out of a hat, or use a computer program to generate random numbers.

2) b = 14.14 (nearest hundredth)
c = 15.36 (nearest hundredth)
Step-by-step explanation:
Sine Rule
[tex]\sf \dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}[/tex]
(where A, B and C are the angles and a, b and c are the sides opposite the angles)
Question 1
The interior angles of a triangle sum to 180°

Given:
A = 55°B = 35°C = 90°c = 20[tex]\implies \sf \dfrac{a}{\sin 55}=\dfrac{b}{\sin 35}=\dfrac{20}{\sin 90}[/tex]
[tex]\implies \sf a=\dfrac{20\sin 55}{\sin 90}=16.38304089...[/tex]

Question 2

⇒ m∠B = 180° - 90° - 23° = 67°
Given:
A = 23°B = 67°C = 90°a = 6[tex]\implies \sf \dfrac{6}{\sin 23}=\dfrac{b}{\sin 67}=\dfrac{c}{\sin 90}[/tex]
[tex]\implies \sf b=\dfrac{6\sin 67}{\sin 23}=14.13511419...[/tex]

Answer:
Answers
Answer:
The volume is 160
Step-by-step explanation:
Explanation: To find the volume of the rectangular prism you need to multiply 8x20. The reason is because there are 20 cubes in each row (i'm sorry if i'm not good at explaining math very well). The way I found the volume was to count the amount of cubes on the side and multiply it by how many rows there were on top. So that brings me to 160. The product of 8x20. (I hope this helps, math isn't my best subject)
Answer:
V = 160 cubic inches
Given that,
Length, width and height of prism are 8 inches, 4 inches and 5 inches
The formula for the volume of a rectangular prism is given by :
So, the volume of the prism is 160 cubic inches.

20 POINTS) Linda has to buy stickers, erasers, and a pencil. She can only spend $3. A sticker costs $0.35, an eraser costs $0.99, and a pencil costs $0.59. Can Linda buy 3 stickers and 2 erasers?
[Use the inequality 0.35x + 0.99y + 0.59 ≤ 3]
Yes, because the total will be $1.62
Yes, because the total will be $2.93
No, because the total will be $3.62
No, because the total will be $5.93
Answers
Answer:
No, because the total will be $3.62
Step-by-step explanation:
When we substitute with 3 and 2 shown below
0.35(3)+0.99(2)+0.59 we get 3.62, which is greater than 3 dollars.
Hope this helped<33
Answer:
Alright so the question states that "She can only spend $3."
A sticker costs $0.35
A eraser is $0.99
A pencil costs $0.59
What you are trying to find is Can Linda buy 3 stickers and 2 erasers.
So add the total value of stickers prices. You need to know what's the cost of 3 stickers and 2 erasers
0.35+0.35+0.35= 1.05+0.99+0.99 = 3.03 So she can't. Now can she buy 1 sticker, 1 eraser, and 1 pencil. So is it enough to get 1 of each item?
0.35+0.99+0.59=1.93 Yeah you can.
But is it enough for her to get 3 stickers, 2 erasers and a pencil?
We already know the cost for 3 stickers and 2 erasers is $3.03. All you need to do is add $0.59 to find the total cost. The total cost of 3 stickers and 2 erasers and a pencil is $3.62. So the answer is No, because the total will be $3.62 and her budget is $3 so she will need extra $0.62 to cover the full cost.

you really want to think of a function as a vending machine. if you selected B12 on a vending machine and got chips, the only thing that you should be getting is chips. B12 represents x, the input value, and the chips represent y, the output value. one input value can only have one output value. in this scenario, we can say that (5,2) is a function because we don’t have another 5 as an input value.
(0,2) is not an example of an input output value because we already have 0 as an input which would make it have two output values which is not possible. if you pressed B12 and got a drink even though you just got chips from it, that would not be a function.

This drawing should help a lot, and the way you solve the last one is you divide both sides by 2x making it an equation you can use to solve the graph.
Step-by-step explanation:
remember, y=mx+b, m is the slope because the x is the ever increasing variable of the slope, and b is where you start the line on the y axis, so it makes this much easier knowing that the slope for a whole number, is just putting a 1 underneath it, and it applies to every number even negatives too.
