Susan the author owns a independent bookstore. On Monday,she sells 500 books for $30 each. On Tuesday she sells 50 books for $60 each. On Wednesday she sells 300 books for $80 each. Thursday she sells 400 books for $70 each. Friday she sells 800 books for $800 each. How much money did she make those 5 days?
Answer:
She made $710,000.
Step-by-step explanation:
First, let's multiply how many books she sells per day to the price for each of them. 500x30= 15000, 50x60=3000, 300x80=24000, 400x70=28000, and lastly, 800x800=64000. Next, add up all the numbers to get your total of $710,000!

MATH
Answer:
Radius = 2.5559cm
To the nearest tenth = 3cm
Step-by-step explanation:
Volume of bottle = 160cm³
Height of bottle = 7.8cm
π = 3.14
Radius of bottle = r
Using the formula,
V = πr²h160 = (3.14)(r)²(7.8)
160= 24.492r²
Dividing both sides by 24.492,
160/24.492 = r²
r² = 6.5327, which is approximately 6.533
Making r the subject,
r = √6.533
r = 2.5559, which is approximately 2.556
Round to the nearest tenth = 3
Therefore, the radius of the cylindrical bottle is 3cm.

12. A wall contains a rectangular window. The area (in square feet) of the window is represented by x ^ 2 - 14x + 48
a. Write a binomial that represents the height of the window.
b. Find the perimeter of the window when the height of the wall is 12 feet.
Answer :
a - binominal = an algebraic expression of the sum or the difference of two terms. So I put it in the perimter 12. 6+12=18. So the width would be 18. 18+12+18+12 = 30+30 = 60. just put that ig ??
Question : Is this RSM? Because if I knew the grade , advanced/normal/honors I would be able to help u more
Solve step by step : x=12 because it said the height is 12.
Inside, x-6, so therefor it would really be, 12-6. Which we know would be 6.
Perimeter : 60
now we know the inside is 6. The outside height is 12. 6+12=18. So the width would be 18. 18+12+18+12 = 30+30 = 60.

Answer:
See below.
Step-by-step explanation:
For this problem, we are asked to find equivalent expressions.
We should use the Distributive Property.
What is the Distributive Property?
The Distributive Property is a property that allows us to multiply the number outside of the parentheses into the numbers inside the parentheses. Think of the Distributive Property in the form of x (y + z); We multiply x with y and z.
Since we know what the Distributive Property is, we can begin finding equivalent expressions.
Let's start by distribution:
[tex]3x+3(x+y)\\3x + 3x + 3y\\6x + 3y[/tex]
A is a correct option.
Let's check B and C.
Distribute:
[tex]3(x+x+y)\\3x+3x+3y\\6x+3y[/tex]
B is a correct option.
Distributing isn't needed for expression C.
[tex]3xy\neq 6x + 3y[/tex]
C is an incorrect option.
A and B are the correct options.
Each equation represents a proportional relationship. Choose the equations for which the constant of proportionality is 1/4
.
A) y = 4x
B) y = 0.25x
C) 4y = x
D) 32y = 8x
E) 1/4y = 2x
Answer: E)1/4y=2x
Step-by-step explanation:
The constant of proportionality represents the ratio between the dependent and independent variables in a proportional relationship. If the constant of proportionality is 1/4, it means that the dependent variable is one-fourth the value of the independent variable.
So, we need to determine which equations have a constant of proportionality of 1/4:
A) y = 4x
The constant of proportionality in this equation is 4, not 1/4.
B) y = 0.25x
The constant of proportionality in this equation is 1/4.
C) 4y = x
The constant of proportionality in this equation is 1/4, since we can rewrite it as y = 1/4x.
D) 32y = 8x
We can simplify this equation by dividing both sides by 8:
4y = x
The constant of proportionality in this equation is 1/4.
E) 1/4y = 2x
We can rewrite this equation as:
y = 8x
The constant of proportionality in this equation is 8, not 1/4.
Therefore, the equations for which the constant of proportionality is 1/4 are B), C), and D).
Answer:
B, C, D
Step-by-step explanation:
You want to identify the equations that have a constant of proportionality of 1/4.
Proportional relationA proportional relationship can be written in the form ...
y = kx
where k is the constant of proportionality.
You want to identify those relations that are equivalent to this with k=1/4.
ChoicesA) y = 4x . . . . . k = 4 ≠ 1/4
B) y = 0.25x . . . . . k = 0.25 = 1/4
C) 4y = x ⇒ y = 1/4x . . . . . k = 1/4
D) 32y = 8x ⇒ y = 8/32x = 1/4x . . . . . k = 1/4
E) 1/4y = 2x ⇒ y = 2/(1/4)x = 8x . . . . . k ≠ 1/4
The relations with a constant of proportionality of 1/4 are B, C , D.

20 points and guaranteed brainliest!! A rectangular prism is 3 inches long, 5 inches wide, and has a height of 6 inches. What is its surface area?
90 in 2
120 in 2
126 in 2
63 in 2
Answer: 126 in ^2
Step-by-step explanation:
The surface area of a rectangular prism is given by the formula:
Surface Area = 2lw + 2lh + 2wh
where l, w, and h are the length, width, and height of the rectangular prism, respectively.
Substituting the given values, we get:
Surface Area = 2(3)(5) + 2(3)(6) + 2(5)(6)
Surface Area = 30 + 36 + 60
Surface Area = 126 square inches
Therefore, the surface area of the rectangular prism is 126 in^2.
Answer: 126!!

-Graphing Linear equalities with slope and y-intercept-
Answer:
slope = 1
y-intercept = -3
equation: y = x - 3
Step-by-step explanation:
slope = (y₂ - y₁) / (x₂ - x₁)
choose any 2 consecutive x. y pairs and plug the numbers into the equation. I pick (0, -3) and (1, -2)
slope = (-2 - -3 / (1 - 0) = 1/1 = 1
y-intercept = -3 this is where the line crosses the y axis at point (0, -3)
Equation: y = mx + b = (1)x + (-3) = x - 3
y = x - 3
To draw the graph, it's easy (sorry, Brainly doesn't provide drawing tools):
put the first point at (0, -3) then go up 1, over 1, up 1, over 1, etc. because the line has a slope of 1/1.
the line should slant up because it has a positive slope
The local High School currently has approximately 950 students
enrolled. They are anticipating a 12% increase next year. How many
students are they anticipating?
Answer:
1064
Step-by-step explanation:
To calculate the number of students the high school is anticipating next year, we need to find 12% of the current enrollment and add it to the current enrollment:
12% of 950 = 0.12 * 950 = 114
So the high school is anticipating an additional 114 students next year.
To find the total anticipated enrollment, we add the additional 114 students to the current enrollment of 950:
Total anticipated enrollment = 950 + 114 = 1064
Therefore, the high school is anticipating 1064 students next year.
