price is 40% below the list price. Find the rate of discount and profit?
Answers
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
=0.25x

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.

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.

Answer:
First one will be 2
Second one will be 10
Third one will be undefined
Explanation:
So for the first one you are substituting x for -3 so then the equation would look like this: -3^2+9/-3^2, this will equal to 9+9/9 which your answer would be 2 since 18/9 is 2. For the second one it will look like this -1^2+9/-1^2 which would be 1+9/1, this would equal to 10. For the last one it will look like this 0^2+9/0^2 which would just be 0+9/0 9/0 would be undefined.

Calculate the average rate of change for the given function, from x = −3 to x = 7.
Answers
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:
Average rate = -5The difference of five times a number and 6 totals 29
Answers
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.

Answers
Answer:
$16.48
Step-by-step explanation:
Create a proportion where x is the cost of 44 pounds of steak:
[tex]\frac{55}{20.60}[/tex] = [tex]\frac{44}{x}[/tex]
Cross multiply and solve for x:
55x = 906.4
x = 16.48

Which is the best estimate for 19% of 205?
A- 40
B- 50
C- 100
D- 400
Answers
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.

Please help ❤️ complete the table leave the graph bit as I know how to do it
Answers
Answer:
(0,6)
(1,5)
(2,4)
(3,3)
(4,2)
Step-by-step explanation:
To solve this table first convert the equation to slope-intercept form (y=mx+b), to do this solve for y in the equation. The slope-intercept form is y=-x+6, where -1 is the slope and 6 is the y-intercept. Then from that, you can get your first point, because you know the y-intercept is 6, therefore when x equals 0 y must be 6. Next, because the slope is -1 that means the y-value decreases by 1 every time the x-value increases by 1. So to find the rest of the y-values simply subtract 1 from the previous y-value.
