of 80 points. This season, her average score has been 72 points.
What is the percent of decrease in Kathleen's average score?
Answers
(|currentavg-initialaverage|/initialavg)*100 gives percent difference so:
(|72-80|)/(80)*100
gives a 10 percent difference (decrease)
72 X%
X%=72•100/80
X=90 %
100-90=10%
Decrease in Kathleen’s average score is 10%. Good luck.

Suppose WX = 4x - 8 and WZ = 2x + 2. Solve for x
Answers
Answer: 5
Step-by-step explanation:
Because the shape is a kite we can tell that WX and WZ are congruent.
So 4x-8 = 2x+2
Add 8 to both sides
4x = 2x+10
Subtract 2x
2x = 10
Divide by 2
x = 5

Answers
Answer:
x = 256/3
Step-by-step explanation:
3/8x - 16 = 16
Add 16 to both sides
3/8x = 32
Multiply 8 by both sides
3x = 256
Divide 3 by both sides
x = 256/3 or 85.3333333

None of he choices are correct. Now before you say I'm wrong, look at any one of the unknown angles. You can plainly see that they each are greater than 90 °.
x = 120°
Step-by-step explanation:
5 sides
(180 x 5) - 360 = 540° total of interior angles
540 - 90 - 90 = 360° total for the 3 unknown angles
x = 360/3 = 120°

A certain drug is made from only two ingredients: compound A and compound B. There are 3 milliliters of compound A used for every 4 milliliters of compound B. If a chemist wants to make 378 milliliters of the drug, how many milliliters of compound B are needed?
Answers
Answer:
216 milliliters
Step-by-step explanation:
Since, there are 3 milliliters of compound A used for every 4 milliliters of compound B.
Therefore,
A : B = 3 : 4
Let the common multiplier of the given ratios be x.
So, A = 3x & B = 4x
Since, chemist wants to make 378 milliliters of the drug.
Therefore, total volume of drug = 378 milliliters.
3x + 4x = 378
7x = 378
x = 378/7
x = 54
4x = 4*54 = 216
Thus, 216 milliliters of compound B are needed.

Then why are you even doing that?
Step-by-step explanation:
Triangle G F E is cut by line segment H J. Line segment H J goes from side G E to F E. The length of G F is 4 x minus 4, the length of H J is x + 3, and the length of J E is x minus 1.
If H is the midpoint of GE and J is the midpoint of FE, determine the following lengths.
HJ =
JE =
Answers
Answer:
HJ = 8 JE = 4
Step-by-step explanation:
it is given that H is the midpoint of GE and J is the midpoint of FE. According to the midpoint theorem the line segment connecting the midpoint of two sides is parallel to the three side and its length is half of the third side. since JH is connecting the midpoints.
HJ= 1/2 (GF)
x + 3 = 1/2 (4x - 4)
x + 3 = 2x - 2
x = 5
^ Thus meaning the value of x is 5.
Now you just fill into your equations:
HJ = x + 3 = (5) + 3 = 8
JE = x - 1 = (5) - 1 = 4
Therefore, HJ = 8; JE = 4.
Answer:
HJ = 8
JE = 4

Answers
Answer:
If we are talking about a triangle with two sides being of equal length: 11, then you can use Pythagorean Theorem to solve.
Step-by-step explanation:
Imagine the sides labeled as a, b, and c. a and b are both 11. We have to find the value of c. we can do this by writing a^2+b^2=c^2. so 11^2+11^2=c^2. All that is left to do is find the square root of c^2 and you are left with your answer.
