The library had 301 shelves of books. Each shelf had 13 books. Librarians checked out 807 books to students. How many books does the library have remaining
Answer:
3106 books
Step-by-step explanation:
From the question:
The library had 301 shelves of books. Each shelf had 13 books.
Hence, the total number of books in the library =
Number of shelves × Number rod books in a shelf
= 301 × 13 books
= 3913 books
The total number of books in the library is 3913 books
Librarians checked out 807 books to students.
How many books does the library have remaining?
This is calculated as:
Total number of books - Number of books checked out
= 3913 books - 807 books
= 3106 books
The library has 3106 books remaining.

What is the value of n in the equation 1/2(n-4)-3=3-(2n+3)
Answer:
2
We first use the distributive property on both sides:
1/2(n)-1/2(4)-3 = 3-(2n)-(3)
1/2n - 2 - 3 = 3 - 2n - 3
Combining like terms on both sides,
1/2n - 5 = -2n
Subtracting 1/2n from both sides:
1/2n - 5 - 1/2n = -2n - 1/2n
-5 = (-2 1/2)n
Divide both sides by -2 1/2:
-5/(-2 1/2) = (-2 1/2)n/(-2 1/2)

for each new tire.
Answer:
Inequality: 95 ≤ x ≤ 145
Minimum = 95
Maximum = 145
Step-by-step explanation:
Given
Budget = $120
Range = $25
Solving (a) Write an inequality to determine how much she could spend.
The range implies that she can spend less or more of the budgeted amount.
Let the amount to spend be represented by x.
If she spends more, the maximum would be
Max = Budget + Range
Max = 120 + 25
Max = 145
If she spends less, the minimum would be
Min = Budget - Range
Min = 120 - 25
Min = 95
So, this means that x could fall within the range of the minimum and the maximum.
Mathematically, this is:
Min ≤ x ≤ Max
So, the inequality would be:
95 ≤ x ≤ 145
Solving (b): The minimum and maximum.
The minimum and the maximum amount have been solved in (a) above.
Minimum = 95
Maximum = 145

Linda needs 2200 calories per day to maintain her present weight and daily activities. She wants to lose x pounds per day. Each pound of body weight lost is equivalent to 3400 calories. Write her daily calorie intake as a linear function of the number of pounds of weight lost per day. (Let y represent the calorie intake and x represent the number of pounds of weight lost per day.)
Answer:
y = - 5600x + 2200
Step-by-step explanation:
Given that:
x = number of pounds lost per day
y = calorie intake
Using the linear relation :
y = mx + c
When calorie intake = 2200, no loss or gain in weight ; x = 0 ; hence intercept c = 2200
y = 0 + 2200
Each pound of body weight lost = - 3400 calories
Hence, equation when x = 1
-3400 = m(1) + 2200
-3400 = m + 2200
-3400 - 2200 = m
-5600 = m
Hence,
y = mx + c
y = - 5600x + 2200

5. AAA Dance Shoes makes dancing shoes with leather soles. The shoes cost $29 each to
manufacture. The fixed cost for the product line is $45,000. The company has
determined their demand function to be q=-200p+30,000, where p is the price for each
pair of shoes. What is the revenue function in terms of price? S
(10 Points)
R
200p + 915,000
O R = -200p + 30,000
O R = -200p2 + 30,000
O R = 200p2 + 870,000
Answer: 200p² + 870,000
Step-by-step explanation:
Revenue is calculated as price multiplied by quantity. In this case,
Price = P
Quantity (Q) = q=-200p+30,000
Revenue = p × q
Revenue = (200p + 30,000) × p
= 200p² + 30000p
= 200p² + 30000(29)
= 200p² + 870,000
The revenue function is 200p² + 870,000

Janine babysits for $14.50 per hour. She also works as a dishwasher at her family's restaurant for $9.50 per hour. Her family needs her to be at the restaurant at least 7 hours per week, but she can't work there more than 10 hours per week. She also does not want to work more than a total of 15 hours each week. She wants to make at least $140 per week.
Write a system of inequalities that represents the constraints on Janine's part-time jobs. Explain what your inequalities represent in the context of the problem.
Janine wants to earn as much money as possible next week. What combination of hours should she spend at each job to do this? Justify your reasoning.
Answer:
1) The system of inequalities are
14.5·x + 9.5·y ≥ 140
7 ≤ y ≤ 10
x + y ≤ 15
2) 14.5·x + 9.5·y ≥ 140 represents the total amount of money Janine can earn
7 ≤ y ≤ 10 represents the range of values, Janine can spend dishwashing
x + y ≤ 15 represents the total number of hours Janine will like to work each week
3) 8 hours babysitting, 7 hours dishwashing
Step-by-step explanation:
The given parameters are;
The amount per hour Janine makes from babysits = $14.50
The amount per hour Janine makes from dishwashing = $9.50
The minimum number of hours Janine can spend dishwashing = 7 hours
The maximum number of hours Janine can spend dishwashing = 10 hours
The maximum number of hours Janine can work each week = 7 hours
The minimum amount she wants to make each week = $140
Let x represent the number of hours Janine spends babysitting and let y represent the number of hours Janine spends dishwashing
1) From the question, we have;
14.5·x + 9.5·y ≥ 140
7 ≤ y ≤ 10
x + y ≤ 15
2) Where
14.5·x + 9.5·y ≥ 140 represents the total amount of money Janine can earn
7 ≤ y ≤ 10 represents the range of values, Janine can spend dishwashing
x + y ≤ 15 represents the total number of hours Janine will like to work each week
Making, y, the subject of the formula of the above inequalities and plotting as functions is given as follows;
y ≥ 140/9.5 - (14.5/9.5)·x
y ≤ 15 - x
3) In order to earn as much money as possible given that the amount Janine earns from babysitting is more than the amount she earns from dishwashing, Janine should spend the least amount of time dishwashing, which is 7 hours, as given, and then spend the remaining 8 hours babysitting to receive $14.5 × 8 + $9.5×7 = $182.5
Janine should work as a dishwasher for 7 hours, and as a babysitter for 8 hours, to earn as much money
Represent the hours babysitting with b, and the hour dishwashing with d.
So, we have the following systems of inequalities
[tex]14.5b + 9.5d \ge 140[/tex] ---her earnings[tex]7\le d \le 10[/tex] -- the time she can spend at the restaurant[tex]b + d \le 15[/tex] --- her weekly work hoursNext, we plot the graphs of the inequalities that represent the hours she can work.
i.e. the graphs of [tex]7\le d \le 10[/tex] and [tex]b + d \le 15[/tex]
From the attached graph, we have the following possible values
[tex](b,d) =(5,10) (8,7)[/tex]
Substitute these values in [tex]14.5b + 9.5d \ge 140[/tex]
So, we have:
At (5,10):
[tex]Earnings = 14.5 \times 5 + 9.5 \times 10[/tex]
[tex]Earnings = 167.5[/tex]
At (8,7):
[tex]Earnings = 14.5 \times 8 + 9.5 \times 7[/tex]
[tex]Earnings = 182.5[/tex]
The earnings at point (8,7) is greater than (5,10).
Hence, she should work as a dishwasher for 7 hours, and as a babysitter for 8 hours, to earn as much money

there were 40 questions on Roberts test. How many problems did Robert get right if he received an 87.5% oh his test?
Answer:
Robert got 35 problems right if he received an 87.5% oh his test.
Step-by-step explanation:
Total questions = 40As Robert got right 87.5% on his test.
so the expression becomes
87.5% × 40
= 87.5/100 × 40
= 0.875 × 40
= 35
Therefore, Robert got 35 problems right if he received an 87.5% oh his test.
