Answer:
kn=15
nm=20
Step-by-step explanation:
The lengths of sides KN and NM of the kite
KN = 15 units
NM = 20 units
What is kite's shape?A kite is a quadrilateral with four sides that may be divided into two neighboring pairs of equal length sides. A parallelogram, on the other hand, has two sets of equal-length sides, but they are opposed to one another as opposed to being adjacent.
Given:
KLMN is a kite.
According to the given kite,
KN = KL........ (1)
and LM = NM........ (2)
From equation (1)
y + 10 = 2y + 5
y = 5.
Now,
3x -1 = 2x + 6
x = 7
We get,
LM = MN = 20
KN = 15 units
NM = 20 units

What information is missing but is needed to solve this problem?
The community theater staged performances on Friday, Saturday, and Sunday. There were 357 people at Friday's performance and 422 at Sunday's performance. How many people attended Saturday's performance?
A)the number of people at Friday's, Saturday's, and Sunday's performances combined
B)the number of people at Friday's and Sunday's performances combined
C)the difference between the number of people at Friday's and Sunday's performances
D)the average of the number of people at Friday's and Sunday's performances
Answer:
a. the number of people at Friday's, Saturday's, and Sunday's performances combined.
Step-by-step explanation:
The reason this information is needed to solve this problem is because we are looking to find the number of people who attended Saturday's performance. Without any information on Saturday's performance, there is no way to solve the problem. We are given the number of people on Friday and Sunday's performance, but are not given a total amount of people on all performances.
Answer:
A) The number of people at Friday's, Saturday's, and Sunday's performances combined.
Step-by-step explanation:
We are looking for the amount of people who attended Saturday's performance, but only one of the answers contains anything about Saturday, which is A. All the information in the other 3 choices we already know, because we know the amount of people at both Friday and Saturday's performance, so we can do some simple math to figure it out.

Exponent of y?
Answer:
[tex] x^{33} [/tex]
Step-by-step explanation:
[tex] \dfrac{x^8y^{-26}}{x^{14}y^{-5} \times x^{-39}y^{-21}} = [/tex]
A negative exponent in the numerator is a positive exponent in the denominator.
A negative exponent in the denominator is a positive exponent in the numerator.
[tex] = \dfrac{x^8y^{5}x^{39}y^{21}}{x^{14}y^{26}} [/tex]
[tex] = \dfrac{x^{8 + 39} y^{5 + 21}}{x^{14}y^{26}} [/tex]
[tex] = \dfrac{x^{47} y^{26}}{x^{14}y^{26}} [/tex]
[tex] = x^{47 - 14} y^{26 - 26} [/tex]
[tex] = x^{33} y^{1} [/tex]
[tex] = x^{33} [/tex]
How do the graphs of the functions f(x) = (Three-halves)x and g(x) = (Two-thirds)x compare?
Answer:
The answer to this question can be defined as follows:
Step-by-step explanation:
Given:
[tex]\bold{f(x)= (\frac{3}{2})^x}\\\\\bold{g(x)= (\frac{2}{3})^x}\\[/tex]
Following are the graph attachment to this question:
The second function, that is [tex]g(x)= (\frac{2}{3})^x[/tex] is not even a function.
Remember that g(x) function is the inverted f(x) function. And when you see this pattern, a reflection on the Y-axis expects you.
Reflection in the axis.
In x-axis:
Increase the function performance by -1 to represent an exponential curve around the x-axis.
In y-axis:
Increase the input of the function by -1 to represent the exponential function around the y-axis.
We want to compare the graphs of the two given functions. We will see that the graph of g(x) is the graph of f(x) reflected across the line y = x.
The given functions are:
f(x) = (3/2)*x
g(x) = (2/3)*x
Note that each point on the line f(x) is written as:
(x, (3/2)*x)
And each point on the line g(x) is written as:
(x, (2/3)*x)
Now, if we multiply both sides of the above point by (3/2) we will get:
((3/2)*x, x)
Now, remember that for a general point (x, y), if we apply reflection across the line y = x, we get.
(y, x)
So the order of the values changes, exactly as we can see for f(x) and g(x).
Then we can conclude that g(x) is obtained by reflection f(x) across the line y = x.
Then the graph of g(x) is the graph of f(x) reflected across the line y = x.

A 3-gallon container of window cleaner costs $15.84. What is the price per quart?
*Hint: 1 gallon = 4 quarts*
HURRY DUE SOON PLEASE AND THANK YOU :)
Answer:
1.32
Step-by-step explanation:
3 gallon = 1
12 quarts = 4
12 quarts =1
$15.84= 1.32
Answer:
$1.32 per quart
Step-by-step explanation:
To find the price per quart, we must divide the price by the number of quarts.
price / quarts
We are told that a 3 gallon container costs $15.84. First, we must find out how many quarts are in 3 gallons.
We know that 1 gallon is equal to 4 quarts.
Let’s set up a proportion.
quarts/ gallons = quarts/ gallons
4 quarts /1 gallon = x quarts/ 3 gallons
4/1= x/3
Multiply both sides by 3
3*4/1= x/3*3
3*4/1=x
3*4=x
12=x
There are 12 quarts in 3 gallons.
Now we know how many quarts are in 3 gallons. We can find the price per quart.
price / quarts
It costs $15.84 for 12 quarts.
$15.84/12 quarts
Divide 15.84 by 12
$1.32 / quart
It costs $1.32 per quart of window cleaner.

Answer:
f1: 0.440, f2: 0.931, f3: 1.519
Step-by-step explanation:
To solve the system of equations we need to use the inverse of matrix A, as follows:
A x F = C
A^-1 x A x F = A^-1 x C
I x F = A^-1 x C
where I is the identity matrix.
The inverse of A is:
1.450 -0.392 -0.090
A^-1 = -0.074 -0.022 0.1536
-0.406 0.7122 -0.060

e. She makes the lemonade, but her friend complains that it is too weak. Write a ratio of lemon juice to water that may fix the problem
f. Does Sarah need more lemon juice than water to make it stronger?
Answer:
a. 2/5 and 2:3
b.
c. 6
d. 40% and 60%
Step-by-step explanation:
a) The ratio of lemon juice to water as a fraction can be expressed as: 2/3.
b) The amount of water Sarah needs when she has 1¹/₂ cups of lemon juice, is: 2.25 cups
c) The amount of lemon juice Sarah should add to 9 cups of water is: 6 Cups
d) 40% of the lemonade is lemon juice, and 60% is water.
e) She should increase the ratio to 3:2
f) Yes, Sarah would need more lemon juice than water to make the lemonade stronger.
How to solve Ratio Problems?a. The ratio of lemon juice to water as a fraction can be expressed as: 2/3.
b. The amount of water Sarah needs when she has 1¹/₂ cups of lemon juice, is solved as:
1¹/₂ cups of lemon / water = 2/3
³/₂ cups of lemon / water = 2/3
Cross multiply to get:
water = 9/4
water = 2.25 cups
c. The amount of lemon juice Sarah should add to 9 cups of water is as follows:
lemon juice / 9 = 2/3
Cross multiply to get:
lemon juice = 18 / 3
lemon juice = 6 cups
d. The percentage of lemon juice and water in the lemonade if the total volume is 5 cups is:
Lemon juice: (2/5) * 100% = 40%
Water: (3/5) * 100% = 60%
e. What Sarah can do is to increase the ratio of lemon juice to water. One possible ratio could be 3 parts lemon juice to 2 parts water, or 3:2.
f. Yes, Sarah would need more lemon juice than water to make the lemonade stronger.

The sum of the interior angles of a regular polygon is 1800 degrees. How many sides does is have? *
1 point
9 sides
10 sides
11 sides
12 sides
Answer:
12 sides
Step-by-step explanation:
To find the number of sides of a regular polygon with the sum of interior angles of 1800 degrees, we will follow the steps below;
first write down the formula for finding sum of the interior angle of a polygon
s= (n-2)180
where s is the sum of the interior angle and n is the number of side
from the question given, sum of the interior angle s=1800 degrees
substitute s=1800 degree into the formula and solve for n
s= (n-2)180
1800 = (n-2)180
divide both-side of the equation by 180
1800/180 = n-2
10 = n - 2
add 2 to both-side of the equation
10 + 2 = n
12 = n
n= 12
The polygon have 12 sides

You could do this with two weighings assuming its a two pan balance - (1) place three balls on each side - if they balance out then its the remaining three that has abnormal ball (2) out of that group, place one ball on each side - if balances it out, the abnormal ball is the remaining one.
If the weighing in step (1) does not balance out, grab the group of three balls that is light or heavy and repeat step (2) described above.
