why do you multply by a power of 10 when writing a repeating decimal as a fraction
Answers
The goal is to multiply by a certain number (10, 100, 1000, etc.) so that when the original number is subtracted from the multiple, the repeating element cancels out. 10x = 2 is the result of multiplying by ten.

Find the value of x and KL if K is between J and L.
1. JK = 6 x , KL = 3 x , and JL = 27
2. JK = 2 x , KL = x + 2, and JL = 5 x – 10
Answers
Answer:
Step-by-step explanation:
1) JK + KL = JL
6x + 3x = 27
9x = 27
x = 27/9
x = 3
2) JL = JK + KL
5x - 10 = 2x + x + 2 {Combine like terms}
5x - 10 = 3x + 2
Add 10 to both sides
5x = 3x + 2 + 10
5x = 3x + 12
Subtract 3x from both sides
5x - 3x = 12
2x = 12
Divide both sides by 2
x = 12/2
x = 6

Sandra has 4 math tests this marking period. She recieved 90%, 87%, and 92% on the first 3. with is the minimal score she needs on her last test in order to average at least 90% in math class?
Answers
The minim she can get for a score is a 90%
(Sum of the scores)/(number of tests) = avg
(90+87+92+x)/4 = 90
(269+x)/4 = 90
269 + x = 90*4
269 + x = 360
x = 360-269 = 91
So Sandra needs a minimal score of 91% on her last test in order to average at least 90% in math class
I hope this helps :)

a ballroom had a square dance floor. The area of the floor is 400 square feet. If the length of each side of the square increased by one foot, would its area be a rational number?
Answers
Answer:
Yes
Step-by-step explanation:
The area of a square is equal to the length squared.
So, the length of one side of the original floor is √400 which equals 20.
If you increase the length by 1, the area of the dance floor is 21 squared.
21 * 21 is certainly a rational number.
Answer:
Step-by-step explanation:
I think so, yes.
The area of a square is A = s*s where s is the length of the side
s^2 = 400
sqrt(s^2) = sqrt(400)
s = 20
If you increase each dimension by one foot you get 21 * 21 for the area of the new ballroom.
The result is rational. That's because the square root was rational when you found 20.
Area = 21 * 21 = 441 which is rational.
What is the y-intercept of the line whose equation is y=-x-2?
Select one:

D,.1
Answers
Answer:
-2
Step-by-step explanation:
If we have an equation of the form y = mx +b then the y-intercept is b.
So now here we have y =-x - 2. Therefore b = -2 and we conclude the y-intercept is -2.
