Answer:
7,500 copies
Step-by-step explanation:
First, write the problems as equations. There will be one variable: copies (c):
Company A: .05c + 300
Company B: .01c + 600
In order to find when the companies charge the same amount, Company A = Company B. Using the transitive property you get:
Company A = Company B
.05c + 300 = .01c + 600
Now, you just need to solve for c:
.05c + 300 = .01c + 600
.05c = .01c + 300
.04c = 300
c = 7,500
In conclusion, the companies will charge the same amount of money when 7,500 copies are made in a month.

Rebecca decides that this building will be too small at a scale of 1 cm = 3 m. She changes the plan to be at a 1 cm = 4 m scale. What will be the area of the circular pool when it is constructed at this scale?
Answer:
A. 78.5m^2
Step-by-step explanation:
To find the area of a circle you have to do:
Area = πr^2
The diameter is 2.5 x 4 which equals 10 and radius is half the diameter, so 5. Now your equation would be:
Area = π5^2
Solve:
π x 5^2
5^2 = 5 x 5 = 25
π x 25
π ≈ 3.14
3.14 x 25 = 78.5
Answer:
π5^2 ≈ 78.5
78.5m^2

its an input and output table
Step-by-step explanation:
Can someone tell me how I solve this, like explain how I do the steps not just the answer
==================================================
Explanation:
Pick any two rows from the table to form (x,y) points
I'll select the first two rows.
(x1,y1) = (-4,-3) from row 1
(x2,y2) = (0,-2) from row 2
Plug those values into the slope formula
m = (y2-y1)/(x2-x1)
m = (-2-(-3))/(0-(-4))
m = (-2+3)/(0+4)
m = 1/4
The slope is 1/4, which is also the rate of change.

Which shows two expressions that are equivalent to (Negative 7) (Negative 15) (Negative 5)?
-525 and (35)(-15)
Step-by-step explanation:
You can calculate the result of this expression as follows:
(-7)(-15)(-5)=(-1)³(7×15×5)=-(7×15×5)=-525
as, (-1)^n=1 if n is even and (-1)^n=-1 if n is odd.
We already saw that -525 is equivalent to the expression. Furthermore:
(-7)(-15)(-5)=(-15)(-7)(-5)=(-15)(-1)²(7×5)=(-15)(7×5)=(-15)(35).
so the second expression is also equivalent.
You can discard the third and fourth answers because 115×5=575≠525. The first one is also discarded, because (-7)(75)=525≠-525.
The value of equivalent expression are, (- 1)(525) and (35)(- 15).
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Now, We can check all the options as,
(- 7) (-15) (- 5)
= (105)(-5)
= - 525
(–7)(–75) and (–1)(525)
= 525 & - 525
Not Equal
(–1)(525) and (35)(–15)
= -525 and - 525
Both Equal to (- 7) (-15) (- 5)
(35)(–15) and (115)(–5)
= -525 and - 575
Not Equal
(–1)(525) and (115)(–5)
= -525 and - 575
Not Equal
Hence, Expressions (- 1)(525) and (35)(- 15) are equivalent to (- 7) (-15) (- 5).

Answer:
All real numbers.
Step-by-step explanation:
If both sides, when simplified, equals each other, the answer will be "all real numbers". Simplify the left side. Distribute 2 to all terms within the parenthesis:
2(x + 1) = (2 * x) + (2 * 1) = 2x + 2
2x + 2 = 2x + 2 ∴ A) All real numbers is your answer.

Louisa has 4 yards of fabric. She uses 25 yard of fabric to make a doll dress. How many doll dresses can Louisa make with the fabric? Choose the number line model that shows the answer.
Answer:
D. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 10 equal parts.
Step-by-step explanation:
This are the options:
A. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 4 equal parts.
B. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 8 parts.
C. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 5 equal parts.
D. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 10 equal parts.
Amount of Fabric owned by Louisa = 4 yards
If she uses 2/5 yards to make a doll dress, to get the number of dolls that 4 yards can make we will say:
1 doll = 2/5 fabric
x doll = 4 fabrics
Cross multiply
2/5 * x = 4*1
2x/5 = 4
cross multiply
2x = 20
Divide both sides by 2:
2x/2 = 20/2
x = 10
This means that she can make 10 dolls using 4 yards of fabric.
Hence the correct option will be
D. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 10 equal parts.

The area of rectangle is 120 m² and its breadth is 8 m. Find the perimeter of the rectangle.
• Area of rectangle = 120 m²
• Breadth = 8m
To find :• perimeter of the rectangle .
Solution:As we know that ,
• Area of rectangle = L× B
=> 120 = L × 8
=> L = 120/8
=> L = 15
Length of the rectangle is 15m .
Now ,
• perimeter of rectangle = 2 (L+B)
=> perimeter of rectangle = 2 (15+8)
=> perimeter of rectangle = 2 ( 23)
=> perimeter of rectangle = 46
Hence, the perimeter is 46 m .
I hope it will help you.

A line passes through points (0, k) and (4,0) and has a slope of –2.5. Which statements are true regarding the graph of the line?
Answer:
A. The equation of the line is y=−2.5x+10.
C. The y-intercept is k.
F. The value of k is 10.
Step-by-step explanation:
A line passes through points (0, k) and (4,0) and has a slope of –2.5. Which statements are true regarding the graph of the line?
A. The equation of the line is y=−2.5x+10.
B. The equation of the line is y=−2.5x.
C. The y-intercept is k.
D. The y-intercept is 4.
E. The value of k is 4.
F. The value of k is 10.
Solution:
The slope of a line is the ratio of the vertical change to the horizontal change. The slope (m) of a line passing through [tex](x_1,y_1)\ and\ (x_2,y_2)[/tex] is:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Given that the line passes through (0, k) and (4,0)
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]-2.5=\frac{0-k}{4-0}\\\\-2.5=\frac{-k}{4}\\\\k=10[/tex]
The equation of the line is given as:
[tex]y-y_1=m(x-x_1)\\\\y-10=-2.5(x-0)\\\\y = -2.5x+10[/tex]
The y intercept is the value of y when x = 0, hence intercept = k
Given the line that passes through points (0, k) and (4,0) and has a slope of –2.5, we need to get the value of "k
The formula for calculating the slope of a line is expressed as:
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\-2.5 = \frac{0-k}{4-0}\\-2.5=\frac{-k}{4} \\Cross \ multiply\\-2.5 \times 4 = -k\\-10 = -k\\k = 10[/tex]
Hence the value of k is 10.

From the coordinate given (0, 10) and (4, 0), we can see that the y intercept and x intercept of the graph is 10 and 4 respectively
