Shawn is a member of a book club. He pays a $50 yearly membership fee and can purchase books through the club for $5 each. His total annual cost is a function of the number of books, b, that he purchases in a year:
C(b) = 5b + 50
What is the total cost if he purchase 17 books in a year?
Answer:
The annual total cost is $135 when he purchases 17 books
Step-by-step explanation:
Given function is:
C(b) = 5b + 50
Here c is the output which is cost and b is the input which is number of books purchased in an year.
In order to find the total cost when he purchases 17 books, we have to put 17 in place of b and find the cost.
So,
Putting b = 17
[tex]C(17) = 5(17) + 50\\= 85+50 = 135[/tex]
Hence,
The annual total cost is $135 when he purchases 17 books

22 is 44% of what number? Will mark brainliest! <3
Answer:
44% of 50 is 22.
This is the case because 50 * 0.44 is 22.
Let me know if you have any other questions :)
Answer:
50
Step-by-step explanation:
44% = 44/100
44/100 × X = 22
X = 22 × 100/44
X = 100/2
X= 50
hence, 44% of 50 is 22
Beth is putting up a fence in her yard so her dog can play outside. She purchased 80 feet of fencing. If the fenced area is a rectangle with a width of 30 feet, what is the length of the fenced area?
Answer:
10 feet
Step-by-step explanation:
The formula for the Perimeter fo a rectangle
= P = 2L + 2W
Where:
L = Length
W = Width
From the question
P = 80 feet
W = 30 feet
Hence:
80 = 2L + 2(30)
80 - 2(30) = 2L
80 - 60 = 2L
20 = 2L
L = 20/2
L = 10 feet
Hence, the length of the fenced area = 10 feet

A clothing store is having a sale. Last week, a coat originally priced at $110 and was discounted by 45%. This week, the coat was discounted by 30% of last weeks sale price. What is the price of the coat after the second discount is applied
Answer:
The price of the coat after the second discount is applied is $42.35.
Step-by-step explanation:
First, you need to find the amount after the first discount by multiplying the original price by 45% and subtracting that amount from the initial price:
$110*45%=$49.5
$110-$49.5=$60.5
Now, you have to find the price of the coat after the second discount by calculating 30% of the price after the first discount and subtracting the result from that price:
$60.5*30%=$18.15
$60.5-$18.15=$42.35
According to this, the answer is that the price of the coat after the second discount is applied is $42.35.

Why do -8 and 8 have the same absolute values?
Answer:
Absolute value means the non-negative, or the positive, of it's number, since eight is already a positive number, it's absolute value remains positive eight.
But since -8 is a negative number, the absolue value will give eight it's non-negative, which is positive eight.

This question is incomplete
Complete Question
Mariah and Clarence are planning for a dinner party. The grocery store is selling a 25- pound turkey for $60 . Mariah states, "that means it costs $2.40 per pound of turkey." Clarence states, "that means $2.4 pounds of turkey cost $1 Is Mariah's statement, Clarence's statement, both statements, or neither statement correct?
Answer:
Mariah's statement is correct
Step-by-step explanation:
Mariah and Clarence are planning for a dinner party. The grocery store is selling a 25- pound turkey for $60 .
From the statements given above, we are to find the unit rate . This means the cost of the turkey per pound
Hence, the calculation is given below:
25 pounds of turkey = $60
1 pound of turkey = x
Cross Multiply
25 × x = $60 × 1
x = $60/25
x = $2.40
1 pound of turkey cost $2.40
Therefore, Mariah's statement is correct
5. The Smith family paid $146.50 for dinner. If they tipped 20%. How much
did they spend total including the tip?
Answer:
$175.80
Step-by-step explanation:
Answer:
175.80$
Step-by-step explanation:
In order to find the answer to this question you must first find 20% of the cost for the dinner, then add that answer to the cost of the dinner to receive your answer.
[tex]146.50[/tex]
[tex]20 =146.50[/tex]
[tex]Y=P\times X[/tex]
[tex]20\times146.50[/tex]
[tex]20\div100=0.2[/tex]
[tex]0.2\times146.50[/tex]
[tex]0.2\times146.50=29.3[/tex]
[tex]=29.3[/tex]
Now add:
[tex]146.50+29.3=175.80[/tex]

(Help needed ASAP I’m confused ) Solve the equation by using the distributive property first
Answer:
x=0
Step-by-step explanation:
simplify: 15(x-3) over 15 ( srry i dont know how to make that a fraction.)
3(2x-3)= 3x-9
3x-9=6x-9
move all terms containing x to the left side of the equation
-3x-9=-9
move all terms not containing x to the right side of the equation
-3x=0
divide both sides by -3 and simplify if needed
x=0

What is the recursive formula for this geometric sequence? 6, -24, 96, -384, ...
Answer:
Option (C)
Step-by-step explanation:
Geometric sequence has been given as,
6, -24, 96. -384.......
First term of this sequence = 6
[tex]a_1=6[/tex]
Recursive formula of geometric sequence is given by,
[tex]a_n=a_{n-1}(r)[/tex]
Here r = common ratio of successive and previous term
From the given sequence,
r = [tex]\frac{a_2}{a_1}[/tex]
= [tex]\frac{-24}{6}[/tex]
= (-4)
Recursive formula of the given sequence will be,
[tex]a_n=a_{n-1}.(-4)[/tex]
Therefore, Option (C) will be the correct option.

19) If you choose from the following M 8 M colors, what is the probability that you choose blue? 5 green 6 yellow 8 blue 7 brown
7/26
3/26
8/26
1/26
What’s the answer
Answer:
The answer is C, or the third one (8/26).
Step-by-step explanation:
You add up all the objects (5+6+8+7) and get a total of 26 objects. Now you go to the amount of blue ones, and it's 8. So your probability of getting a blue one is 8 out of 26, since there's 8 blue ones out of the total 26. You can write this as 8/26, which is the answer.
What is the slope of this line: y=-4x-9
Answer:
-4

Answer:
1086
Step-by-step explanation:
BODMASS (Multiplication first, addition after)...
15×72= 1080
1080+6= 1086
hope it helps
Because of PEMDAS, Simplify 15x72 first. That will bring you to 1080. After that we add 6 to the 1080 because you always do Multiplication first. Your answer would be 1086 if you followed PEMDAS correctly.
PEMDAS:
1. Parentheses
2. Exponents
3. Multiplication
4. Division
5. Addition
6. Subtraction
That's the order of operations if you ever want to know what to do first.
