by the division property of equality.
What is division?Division is the process of splitting a number or an amount into equal parts. Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.
here, we have,
Explanation:
We want to find the correct second step for the given proof.
Recall that from division property of equality, when we have;
a=b and c=d, dividing the equations by each other, the equation will still be equal;
a/c = b/ d
For the given Prove;
statement 1 states that the circumference circle 1 and 2 can be expressed as;
C = 2πr and, C' = 2πr'
So, for step 2;
Applying the division property of equality, we have;
C/C' = 2πr/2πr'
which then equals,
C/C' = r/r'
Therefore, the correct second step for the given proof is;
C/C' = 2πr/2πr' and, C/C' = r/r'
by the division property of equality.

· The list price of an article is 25% above the selling price and the cost
price is 40% below the list price. Find the rate of discount and profit?
Answer:
p=25%
discount=25%
Step-by-step explanation:
Cost Price = 1.25 x - .4(1.25x)= 1.25x- .5x
Cost Price = .75x
S P = C+P
Profit = Selling price - Cost price
= x - 0.75x

To ensure 3 coffee candies you would need to pull 25 - 2 = 23 candies
Calculate the average rate of change for the given function, from x = −3 to x = 7.
Answer:
The average rate of change for the given function, from x = −3 to x = 7 will be:
Average rate = -5Step-by-step explanation:
Given the table
x f(x)
-3 50
3 10
7 0
As the interval is from x = -3 to x = 7.
so
at x₁ = -3, f(x₁) = 50
at x₂ = 7, f(x₂) = 0
Using the formula to determine the average rate of change at which the total cost increases will be:
Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]
= [0 - 50] / [7-(-3)]
= [-50] / [7+3]
= -50 / 10
= -5
Therefore, the average rate of change for the given function, from x = −3 to x = 7 will be:

A movie theater sends out a coupon for 65% off the price of a ticket. Write an equation for the situation, where y is the price of the ticket with the coupon, and x is the original price of the ticket. Use pencil and paper. Draw a graph of the equation and explain why the line should only be in the first quadrant.
Answer:150
Step-by-step explanation:
The equation represents the selling price of a ticket with 65% off on the original price x is y = 0.35x and its graph has been drawn.
How to plot a graph?A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.
After that, we need to substitute the values of x's and y's into the coordinate geometry.
In order to plot the graph, we need to find out y's values corresponding to x's value
As per the given,
x = original price
y = selling price
Since tickets sold 65% off x = (65/100)x = 0.65x
y = x - 0.65x
y = 0.35x

A radio rs 3200 without VAT and rs 3600 including VAT. find the VAT amount and the VAT percentage.
Answer:
amount: rs 400
percentage: 12.5%
Step-by-step explanation:
Before VAT: rs 3200
After VAT: rs 3600
VAT = 3600 - 3200 = 400
VAT = rs 400
percent = part/whole * 100%
percent = 400/3200 * 100%
percent = 12.5%
The difference of five times a number and 6 totals 29
Step-by-step explanation:
Let x represent the number.
We have 5x - 6 = 29 or 6 - 5x = 29.
=> 5x = 35 or 5x = -23
=> x = 7 or x = -4.6.
The number can be 7 or -4.6.
We have 5x - 6 = 29 or 6 - 5x = 29.
=> 5x = 35 or 5x = -23
=> x = 7 or x = -4.6.
The number can be 7 or -4.6.

Which is the best estimate for 19% of 205?
A- 40
B- 50
C- 100
D- 400
The best estimate for expression of 19% of 205 is 40.
Option A is the correct answer.
What is a percentage?The percentage means the required value out of 100.
It is calculated by dividing the required value by the total value and multiplying by 100.
The percentage change is also calculated using the same method.
In percentage change we find the difference between the values given.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
We have,
To find a percentage of a number, we can convert the percentage to a decimal by dividing it by 100.
In this case, we want to find 19% of 205.
To do this, we first convert 19% to a decimal by dividing it by 100:
19 ÷ 100 = 0.19
This tells us that 19% is equivalent to 0.19 as a decimal.
Next, we multiply the decimal by the given number, which in this case is 205:
205 x 0.19 = 38.95
Therefore,
The best estimate for 19% of 205 is 40.

What are the zeros of f(x) = (x - 5)(x - 4)(x - 2)?
O5, -4,2
O 5, -4,-2
O 5, 4,2
O 5, 4, -2
Answer:
The zeros of f(x) are:
[tex]x=5,\:x=4,\:x=2[/tex]
Step-by-step explanation:
Given the expression
[tex]f\left(x\right)\:=\:\left(x\:-\:5\right)\left(x\:-\:4\right)\left(x\:-\:2\right)[/tex]
substituting f(x) = 0 to determine zeros of f(x)
[tex]0\:=\:\left(x\:-\:5\right)\left(x\:-\:4\right)\left(x\:-\:2\right)[/tex]
Using the zero factor principle
if ab=0, then a=0 or b=0 (or both a=0 and b=0)
[tex]x-5=0\quad \mathrm{or}\quad \:x-4=0\quad \mathrm{or}\quad \:x-2=0[/tex]
solving x-5=0
[tex]x-5=0[/tex]
adding 5 to both sides
[tex]x-5+5 = 0+5[/tex]
[tex]x = 5[/tex]
solving x-4=0
[tex]x-4=0[/tex]
adding 4 to both sides
[tex]x-4+4 = 0+4[/tex]
[tex]x = 4[/tex]
solving x-2=0
[tex]x-2=0[/tex]
adding 2 to both sides
[tex]x-2+2 = 0+2[/tex]
[tex]x = 2[/tex]
Therefore, the zeros of f(x) are:

You deposit $300 in a savings account that pays 6% interest compounded semiannually. How much will you have at the middle of the first year? How much at the end of one year?
Answer:
Please check the explanation.
Step-by-step explanation:
a) How much will you have at the middle of the first year?
Principle P = $300
Annual rate r = 6% = 0.06 per year
Compound n = Semi-Annually = 2
Time (t in years) = 0.5 years
Total amount = A = ?
Using the formula
[tex]A\:=\:P\left(1+\frac{r}{n}\right)^{nt}[/tex]
substituting the values
[tex]A=300\left(1+\frac{0.06}{2}\right)^{\left(2\right)\left(0.5\right)}[/tex]
[tex]A=300\cdot \frac{2.06}{2}[/tex]
[tex]A=\frac{618}{2}[/tex]
[tex]A=309[/tex] $
Therefore, the total amount accrued, principal plus interest, from compound interest on an original principal of $ 300.00 at a rate of 6% per year compounded 2 times per year over 0.5 years is $ 309.00.
Part b) How much at the end of one year?
Principle P = $300
Annual rate r = 6% = 0.06 per year
Compound n = Semi-Annually = 2
Time (t in years) = 1 years
Total amount = A = ?
Using the formula
[tex]A\:=\:P\left(1+\frac{r}{n}\right)^{nt}[/tex]
so substituting the values
[tex]A\:=\:300\left(1+\frac{0.06}{2}\right)^{\left(2\right)\left(1\right)}[/tex]
[tex]A=300\cdot \frac{2.06^2}{2^2}[/tex]
[tex]A=318.27[/tex] $
Therefore, the total amount accrued, principal plus interest, from compound interest on an original principal of $ 300.00 at a rate of 6% per year compounded 2 times per year over 1 year is $ 318.27.
