What is the Pythagoras theorem?The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.
|AC|^2 = |AB|^2 + |BC|^2
Given;
Hypotenuse=26ft
Base=10ft
Now,
Hypotenuse^2=base^2+Height^2
26^2=10^2+h^2
676=100+h^2
576=h^2
h=24
Therefore, by Pythagoras theorem the height will be 24ft.

What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
We can solve this system of equations by setting the expressions for y equal to each other and solving for x, then substituting the value of x into one of the equations to find the corresponding value of y.
y = x + 6 ...(1)
y = -0.5x + 3 ...(2)
Setting equations (1) and (2) equal to each other gives:
x + 6 = -0.5x + 3
Solving for x, we get:
x + 0.5x = 3 - 6
1.5x = -3
x = -2
Substituting x = -2 into equation (1), we get:
y = -2 + 6
y = 4
Therefore,
The solution to the system of equations is (x, y) = (-2, 4).

Luis charges a travel fee of $10 plus $25 per month to mow his neighbors' lawns. If most of his customers only get their lawns mowed for 5 to 8 months out of the year, what is the RANGE of this situation?
Answers
Answer:
135 to 210
Step-by-step explanation:
Given
[tex]Base\ Charge = 10[/tex]
[tex]Additional\ Charge = 25[/tex] monthly
Months = 5 to 8
Required
Determine the range of the function
First, we need to determine the function equation.
Let total charges be y and months be x
[tex]y = Base\ Charge + Additional\ Charge * x[/tex]
[tex]y = 10 + 25 * x[/tex]
[tex]y = 10 + 25x[/tex]
When x = 5:
[tex]y = 10 + 25 * 5[/tex]
[tex]y = 10 + 125[/tex]
[tex]y = 135[/tex]
When x = 8
[tex]y = 10 + 25 * 8[/tex]
[tex]y = 10 + 200[/tex]
[tex]y = 210[/tex]
Hence, the range is 135 to 210

Answers
Hi!
So your grade depends on how much the 2 scores are weighted.
BUT, if the 42 and 100 have equal weights of 50/50, you will have a 71% C
If the 100 isn't weighted that much, I'd guess it'd be around 75/25, your grade will be a 56% F

Answers
Given:
The linear parent function, f(x)=x is vertically compressed by a factor of 4 and reflected over the x-axis.
To find:
The new function.
Solution:
The vertical stretch and compression is defined as
[tex]g(x)=kf(x)[/tex]
If k>1, then f(x) vertically stretched by factor k and if 0<k<1, then f(x) vertically compresses by factor [tex]\dfrac{1}{k}[/tex].
In the given problem, linear parent function, f(x)=x is vertically compressed by a factor of 4. So, [tex]k=\dfrac{1}{4}.[/tex]
[tex]g(x)=\dfrac{1}{4}f(x)[/tex]
Then, it is reflected over the x-axis.
[tex]G(x)=-g(x)[/tex]
[tex]G(x)=-\dfrac{1}{4}f(x)[/tex] [tex][\because g(x)=\dfrac{1}{4}f(x)][/tex]
[tex]G(x)=-\dfrac{1}{4}x[/tex] [tex][\because f(x)=x][/tex]
So, the new function is [tex]G(x)=-\dfrac{1}{4}x[/tex].
Therefore, the correct option is B.

Answer:

Step-by-step explanation:
this answer is good on khan academy
The equation to describe the relationship between m and n will be n = 7m.
What is constant of proportionality?Firstly, there is proportional relationship.
Two values x and y are said to be in a proportional relationship if x=ky, where x and y are variables and k is a constant.
The constant k is called constant of proportionality.
In order to find an equation between n and m by dividing n/m
m = 3, n = 21
n/m = 21/3 = 7
n = 7m
Now, check using the other two points
m = 5, n = 35
n/m = 35/5 = 7
n = 7m
m = 8, n = 56
n/m = 56/8 = 7
n = 7m
Hence, The equation to describe the relationship between m and n will be n = 7m.

Esmeralda received a bag of jellybeans that contained a mixture of regular flavored jellybeans and "surprise" jellybeans. The bag advertised that 15% of the jellybeans were "surprise" flavors. If she counted 40 jellybeans in the bag, how many should she expect to be the "surprise" jellybeans? Use the proportion method and scale factor to justify your solution.
Answers
Answer:
6 "surprise" flavors jellybeans
Step-by-step explanation:
From the information given:
The bag contained a mixture of regular flavored jellybeans and "surprise" jellybeans.
There are 40 jellybeans in the bag.
If 15% of the jellybean were "surprise" flavors.
Then, the number of expected "surprise" jellybeans will be:
= 15% of 40 jellybeans
= (15/100) × 40
= 6 "surprise" flavors jellybeans
If 6 surprise jellybean is contained in the bag;
Thus, the number of regular flavored jellybean will be
= 40 - 6
= 34 regular flavored jellybean
