The costume department of a theatre company is making cone-shaped hats for a play set in medieval times. Wash that will be covered with satin over its entire lateral surface area inside and out. The slant height of each hat will remain constant at 20 inches but the radius of the base will vary to accommodate different head sizes. Using 3.14 for pi, the lateral area of the hat can be expressed as a function. Use this information for Exercises 9-11.

What is the Greatest Common Factor of 8 and 76?
Be sure to show your work or explain your process
Answers
The greatest common factor is 4.
You can’t divide 76 by 8 to get a whole number.
The next number that 8 can be divided by is 4.
8/4 = 2
76/4 = 19
Answer:
2|8,76
2|4,38
|2,19
2 and 19 cannot be further divided
Therefore, G.C.F of 8 and 76=2*2=4

If the domain of a relation is all whole numbers between 2.5 and 7.5, and the range contains 6 different values, can you determine whether the relation is a function? Explain your reasoning.
Answers
Answer:
"This relation is not a function as the domain has fewer values than the range, so there must be a domain value which maps to more than one range value."
Step-by-step explanation:
If each element of the domain has a uniquevalue inside the range, the relation is said to be a function.
A relation's domain is a collection of all whole numbers in the range of 2.5 and 7.5, with a total of 6 distinct values.
The range of whole numbers from 2.5 to 7.5 is 3, 4,5,6,7
There must be a domain value that maps to more than one range value since this relation is not a function because the domain contains fewer values than the range.

Drag an drop an answer into each box to correctly complete the sentences. 2/5 hour is closest to [ ]. 5/8 hour is closest to [ ]. Therefore, the best estimate for the total time Maria was with her sister is close to [ ] (0 hours) ( 1/2 hour) ( 1 hour) ( 1 1/2 hour) (2 hours)
Answers
Answer: It was exactly 61 minutes and 50 seconds
Step-by-step explanation:
Answer:
[tex]\text{$\dfrac{2}{5}$ hour $\approx \dfrac{1}{2}$ hour}[/tex]
[tex]\text{$\dfrac{5}{8}$ hour $\approx \dfrac{1}{2}$ hour}[/tex]
[tex]\text{Total $\approx$ 1 hour}[/tex]
Step-by-step explanation:
Time they played a game
[tex]\dfrac{2}{5}=\dfrac{2 \times 2}{5 \times 2}=\dfrac{4}{10}[/tex]
[tex]\text{As $\dfrac{5}{10}=\dfrac{1}{2} \implies \dfrac{4}{10}\approx \dfrac{1}{2} \implies \dfrac{2}{5}\approx \dfrac{1}{2}$ hour}[/tex]
Time they read a book
[tex]\text{As $\dfrac{4}{8}=\dfrac{1}{2} \implies \dfrac{5}{8}\approx \dfrac{1}{2}$ hour}[/tex]
Total time
Therefore, the best estimate for the total time is:
[tex]\implies \dfrac{2}{5}+\dfrac{5}{8} \approx \dfrac{1}{2}+\dfrac{1}{2}=1\; \text{hour}[/tex]
Exact solution
[tex]\begin{aligned}\implies \dfrac{2}{5}+\dfrac{5}{8} & = \dfrac{2 \times 8}{5\times 8}+\dfrac{5\times 5}{8\times 5} \\\\& = \dfrac{16}{40}+\dfrac{25}{40} \\\\& = \dfrac{16+25}{40} \\\\& = \dfrac{41}{40}\\\\ & = \dfrac{40+1}{40}\\\\ & = \dfrac{40}{40}+\dfrac{1}{40}\\\\ & = 1+\dfrac{1}{40}\\\\ & = 1\frac{1}{40}\; \text{hour} \end{aligned}[/tex]

If h(x) = x^2 − 4x − 5, evaluate h(−2).
Answers
Answer: h(-2) = 7
Step-by-step explanation:
h(x) = x^2 − 4x − 5, where x = -2
h(-2) = x^2 − 4x − 5
= (-2)^2 - 4(-2) - 5
= 4 - (-8) - 5 or 4 + 8 - 5
h(-2) = 7
If h(x) = x^2 − 4x − 5, evaluate h(−2).
H(-2)=7
Is the relationship in the table an example of a proportional relationship? Show your work and explain why or why not.
Answers
Answer:
The relationship in the table is not an example of proportional relationship.
Step-by-step explanation:
This is because the difference between 3.38 and 1.69 is 1.69 but the difference between 8.45 and 3.38 is not 1.69 thus making it not a constant slope so this table doesn't represent a proportional relationship.
no, this table doesn’t show an example of proportional relationship. This is because their isn’t a constant relationship between each numbers.

She fills up 230 bottles so the last one is 1/3
Answer:
250 bottles
Step-by-step explanation:
1 bottle = 16oz (ounces)
Total = 4,005oz
(The nearest multiple to 4005 in the 16 times table is 4000) 4000÷16 = 250
250 bottles = 4000oz

Using the names of the emoticons as the domain and the shapes of the emoticons' mouths as the range, make a list of 5 emoticons that make a function.
Answers
I would’ve probably needed help on this too, a very strange way to ask, but the same rules apply as they would to a regular graph.
In order to have a function, we need every value of the domain (the names) to have only one value from the range (emoticons).
A simple answer to this would be to apply each name with the emoticon it is already applied to (but many solutions are possible), {(A, ), (B, ), (C, ), (D, ), (E, )}
This is a pretty confusingly worded question that I’m pretty sure is just testing your understanding of a function and it’s relation between domain and range. I hope this helps, and I can certainly provide a more in depth explanation of the relationship if you need.

The formula for the area of a triangle is 1/2 times base times height.
So for part a it would be 6x4x(1/2)
Which equals 12
For part b the height is 3 and the base is 4
The equation would be 4x3(1/2)
Another way to solve part be is (helpful for problems where you don't know the base of height)
Make a square around the triangle
The dimensions of the square are 3 by 7
The square makes two triangles to solve the area of
Triangle 1 is 3x3(1/2)=21/2
Triangle 2 is 7x3(1/2)=9/2
Now you subtract the area of the two triangles from the square to get the area of the original triangle
21-(21/2)-(9/2)
Which equals 6

8*3=24 so you must multiply 6 by 3 to get 18.
There is a ratio of 8 blue: 6 red.

Frank's Auto Corner recorded its sales for the second quarter (April, May, and June) of 1999. April sales were 89 cars, May sales were 98 cars, and June sales were 115 cars. During the same quarter in the previous year, 1998, the total sales were 287 cars. How many cars were sold at Frank's Auto Corner during the second quarter of 1999? How many more cars were sold during the second quarter of 1999 than in the second quarter of 1998? Explain how you got your answer. (2-step question)
Answers
Answer:
Part 1: How many cars were sold at Frank's Auto Corner during the second quarter of 1999? 302 cars
Part 2: How many more cars were sold during the second quarter of 1999 than in the second quarter of 1998? 15 cars
Step-by-step explanation:
Part 1: How many cars were sold at Frank's Auto Corner during the second quarter of 1999?
How to: Add the number of cars sold during April, May, and June of 1999. This would be: 89 + 98 + 115 = 302 cars
Part 2: How many more cars were sold during the second quarter of 1999 than in the second quarter of 1998?
How to: Subtract the number of cars sold in the second quarter of 1998 from the number sold in second quarter 1999. We are given that 287 cars were sold in the second quarter of 1998 so: 287 - 302 = 15 cars
