What is the length of AD? PLEASE HELP!!!
The dimensions of a rectangular building used to store tools for electrical lineman has a length of 12x+24 feet and the width of 20x-10 feet.
1.Write the expression that represents the area of the building, in terms of x.
2. Write the expression that represents the perimeter of the building, in terms of x.
3. If the perimeter is going to be 220 feet, what are the dimensions of the building.
Answer:
a) Area = 2x² + 3x - 2
b) Perimeter = 64x + 28
c) Length = 60 feet and Width = 50 feet
Step-by-step explanation:
It is given that:
Length of building = 12x + 24
Width of building = 20x - 10
Area = Length * Width
Area = (12x + 24) * (20x - 10)
Area = 12x(20x - 10) +24(20x-10)
Area = [tex]240x^2-120x+480x-240[/tex]
Area = [tex]240x^2+360x-240 = 2x^2+3x-2[/tex]
Perimeter = 2 (Length + Width )
Perimeter = 2 (12x + 24 + 20x - 10 ) = 2 (32x +14 )
Perimeter = 64x + 28
Putting Perimeter = 220
220 = 64x + 28
64x = 220 - 28
64x = 192
Dividing both sides by 64
x = 3
Length = 12(3) + 24 = 36 + 24 = 60 feet
Width = 20(3) - 10 = 60 - 10 = 50 feet
Therefore,
a) Area = 2x² + 3x - 2
b) Perimeter = 64x + 28
c) Length = 60 feet and Width = 50 feet
If a line passes through (4,13) and (6,19) what is the slope? And can you please explain how you got your answer
Answer:
The slope is 3.
Step-by-step explanation:
The equation for slope is either [tex]\frac{y2-y1}{x2-x1}[/tex] or [tex]\frac{y1-y2}{x1-x2}[/tex]. So this should be [tex]\frac{19-13}{6-4}[/tex], which is 3.
Answer:
Slope =

Select one:
A. Substitution Method
B. Elimination Method
Answer: A: substitution method
Step-by-step explanation:
The substitution method is one way of solving systems of equations. To use the substitution method, use one equation to find an expression for one of the variables in terms of the other variable. Then substitute that expression in place of that variable in the second equation.

Mariah has a spinner that has 10 equal sections, each containing a different number from 1 to 10. Mariah determines about how many times the spinner will land on a number that is greater than 7 in 250 spins, and her work is shown below.
P (number greater than 7) = StartFraction Number greater than 7 over Total number of sections EndFraction times number of spins = StartFraction 4 over 10 EndFraction (250) = 100.
What mistake did Mariah make, if any?
Mariah has the formula reversed; it should be the total number of sections over the numbers greater than 7.
Mariah should have used a 3 in the numerator because there are 3 numbers greater than 7.
Mariah should multiply by the number of sections in the spinner rather than the total number of spins.
Mariah calculated the prediction correctly and did not make any mistakes.
Answer:
Mariah should have used a 3 in the numerator because there are 3 numbers greater than 7.

There is a guitar that originally costs $249.99. It is on sale for 15% off. You also have to pay 6% sales tax. How much will you pay for the guitar? Please show work!!!
Answer:
225.24099
Step-by-step explanation:
249.99(0.15) = 37.4985
249.99 - 37.4985 = 212.4915
212.4915(0.06) = 12.74949
212.4915 + 12.74949 = 225.24099
PLEASE HURRY!! What is the location of point A?
Answer:
(-2,1) or Option 4
Step-by-step explanation:
So the way I did it is you look at the row x first then y. So when looking at row x you see that point A is located at -2. Then when you are looking at column y you see that point A is at 1.
So (-2,1) is your answer.
Hope this helps ;)

Show how to rewrite 1/5 with the denominator 10
The denominator is the bottom number.
To change the 5 to 10, you would multiply 5 by 2: 5 x 2 = 10
Because you multiplied the 5 by 2, you also need to multiply the numerator ( top number) by the same amount.
1 x 2 = 2
So 1/5 = 2/10
The answer is 2/10

What is the slope of the line
Answer:
B) 4
Step-by-step explanation:
Use the slope formula:
slope [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Let:
[tex](x_1 , y_1) = (1 , -2)\\(x_2 , y_2) = (2 , 2)\\[/tex]
Plug in the corresponding numbers to the corresponding variables:
slope:
[tex]m = \frac{2 - (-2)}{2 - 1} \\m = \frac{2 + 2}{2 - 1}\\m = \frac{4}{1} = 4[/tex]
B) 4 is your answer.

What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
g(x) = 10 - 2x
For x = 7,
g(7) = 10 - 2 x 7
g(7) = 10 - 14
g(7) = -4
Thus,
g(7) = -4.
