Last month, you joined an online strategy game. When you joined, there were 50 members. Since then, 41 members have quit. What is the percent change in the number of
members from last month to this month?
Amount Decrease
Answer:
82% decrease
Step-by-step explanation:
percent change = (new number - old number)/(old number) * 100%
There were 50 members.
41 left.
50 - 41 = 9
The new number of members is 9.
percent change = (9 - 50)/(50) * 100%
percent change = -82%
A negative percent change is a decrease.

You can verify that your answer is a solution to the original equation by checking if Testing what what testing is a true statement. Which property of equality allows you to do this? A reflexive B transitive C substitution
Answer:
substitution is distributive for letters
ie) when we work out for 2x + 5 and 3x -4
we can set = to each other distribute to find x then plug in.
plug in means substitute.
Step-by-step explanation:
transitive is distributive for values for same coefficients in problem solving like Pythagoras a + b = c. but that is not equation checking unless equation replaces it. Answer is substitution for distributive letters.

Solve
x2 + x - 56 = 0
The answer would be 2x1=x so x would be 2
Step-by-step explanation:
Answer:
x = 7, - 8
Step-by-step explanation:
x^2 + x - 56 = 0
x^2 + 8x - 7x - 56 = 0
x ( x + 8 ) - 7 ( x + 8 ) = 0
( x - 7 ) ( x + 8 ) = 0
x - 7 = 0
x = 7
x + 8 = 0
x = - 8

Determine whether the lines AB and CD would be parallel, perpendicular, or neither?
A(-5,3) and B(-5, 7)
What is the slope of AB?
C(1, 9) and D(-10, 9)
What is the slope of CD?
What are the lines? (parallel, perpendicular or neither)
Answer:
The slope of AB is undefined; the slope of CD is 0; The lines are perpendicular.
Step-by-step explanation:
Line AB would form a vertical line. Slope is Δy/Δx. To go from 3 to 7 (the y-coordinates) you need to go up 4 units. So we would then have Δy/Δx = 4/Δx. To go from -5 to -5 (the x-coordinates) we have to go left or right 0 units. So, Δy/Δx = 4/Δx = 4/0. Anything divided by 0 is undefined. Remember: vertical lines always have an undefined slope.
Line CD would form a horizontal line. To go from 9 to 9 (the y-coordinates) you need to go up or down 0 units. So, Δy/Δx = 0/Δx. To go from 1 to -10 (the x-coordinates) you need to go down 11 units. So Δy/Δx = 0/Δx = 0/1. 0 divided by anything is 0. Remember: horizontal lines always have a slope of 0.
If you picture a horizontal line and a vertical line intersecting, they would both form a right angle when they intersect. By definition, this would make both lines perpendicular.

Match the percent on the left with the appropriate estimate on the right
32% 20%
22% 70%
74% 1/2
51% 30%
Answer:
32% goes to 30%. 22% goes to 20%. 74% goes to 70%. 51% goes to 1/2.
Step-by-step explanation:
Just treat is as rounding. When you round, 32 goes to 30 because the 2 is 4 or less. 22 and 74 each respectively round to 20 and 70. 1/2 is equal to 50%. And 51% rounds to 50%, or 1/2.
The correct value of the percent on the left with the appropriate estimate on the right is,
32% - 30%
22% - 20%
74% - 70%
51% - 1/2
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Given that;
To match the percent on the left with the appropriate estimate on the right.
Now, We can simplify as;
32% = 0.32
22% = 0.22
74% = 0.74
51% = 0.51
20% = 0.20
70% = 0.70
1/2 = 0.5
30% = 0.3
Thus, The correct value of the percent on the left with the appropriate estimate on the right is,
32% - 30%
22% - 20%
74% - 70%
51% - 1/2

You want to get new shoes they are 30.56 how much will the shoes be with 8% tax?
Answer:
Amount of sales tax ≈ $2.44 dollars;
Price with sales tax ≈ $33 dollars;
Step-by-step explanation:
1. Calculate the 'Amount of sales tax':
Formula:
Amount of sales tax =
Sales tax rate × Price without sales tax
Calculation:
Amount of sales tax =
8% × 30.56 =
8/100 × 30.56 =
8 ÷ 100 × 30.56 =
0.08 × 30.56 =
2.4448 ≈
2.44
(Rounded to a maximum of 2 decimals)
2. Calculate the 'Price with sales tax':
Formula:
Price with sales tax =
Price without sales tax + Amount of sales tax
Calculation:
Price with sales tax =
30.56 + 2.4448 =
33.0048 ≈
33
(Rounded to a maximum of 2 decimals)

Answer:86
Step-by-step explanation:
First, you add 102 and 86 because they are already given values
Next, you do 360-188 because a parallelogram always equals to 360 degrees
You should get 172
Then you do 172/2 because 2 angles are missing and you get 86
