36 points! Find the perimeter of the trapezoid shown below
I believe that the answer is 213.03
Please anyone help me on this
Answer:
Standard line equation:
y=ax+b
The point (5,1) is on the line. so :
1=a(5)+b → 1=5a+b
The point (1,-5) is also on the line. Then :
-5=a(1)+b → -5=a+b
Subtract the two equations in terms of a and b. we have:
6=4a → a=3/2 , b=-6.5
y=1.5x-6.5

(Take the=22/7)
curved surface area of cylinder with diameter 21cm and height 5cm.
Answer:
330cm²
Step-by-step explanation:
CSA of a cylinder = 2πrh
(r = d/2 = 21/2 = 10.5 cm)
Putting the values of 2πrh;
2 x 22/7 x 10.5 x 5
2 x 22 x 1.5 x 5 *(10.5/7 = 1.5)
330 cm²
Solve these multi step equations. Show your work. Justify each of your steps. 3(x-8)=10x+18
Answer:
The answer is x= -6
Step-by-step explanation:
3(x-8)=10x+18
3x-24=10x+18
3x-24=10x+18
Both side +24
3x=18+24+10x
Both side -10 x
3x-10x=42
-7x= 42
Both side divided by 7
x= -6

10(p-7)=180 solve for p
Answer
The answer is p=25
Answer:
p = 25
Step-by-step explanation:
Isolate the variable, p. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction
~
First, divide 10 from both sides of the equation:
(10(p - 7))/10 = (180)/10
p - 7 = 180/10
p - 7 = 18
Next, add 7 to both sides of the equation:
p - 7 (+7) = 18 (+7)
p = 18 + 7
p = 25
25 is your answer for p.

What is the solution to the inequality below?
√x>7
Answer:
x > 49
Step-by-step explanation:
We have the inequality Square root of x is greater than 7, to solve. We need to isolate x.
When having a square root, you need to raise the square root to its second power, with that, do the same to 7 on the other sides :
(Square root of x)^2 > 7^2
x > 49

what are the 2 reasons that the Louisiana purchase caused a debate in the usa
It was a debate between the northerners and southerners (forgive my spelling). The northerners feared the addition of more slave states and a corresponding lack of reprenestation of their intrests in the North. For the southern slave holders, new western lands would be a boon (helpful) to enslaved people and the Louisiana purchase threatened to entrench and expand their suffering to western territories.

Given f(x)=0.25(6)x, find f−1(x).
Answer:
f−1(x) = [tex]\frac{4x}{6}[/tex]
Step-by-step explanation:
f(x) = 0.25(6)x, find f−1(x).
f(x) = 0.25(6)x
f(x) = [tex]\frac{6}{4}[/tex]x = [tex]\frac{6x}{4}[/tex]
f(x) = y
y = [tex]\frac{6x}{4}[/tex]
Substitute y for an x & x for a y
x = [tex]\frac{6y}{4}[/tex]
Multiply both sides by 4
4( x ) = 4( [tex]\frac{6y}{4}[/tex] )
4x = 6y
Divide both sides by 6 to solve for y
[tex]\frac{4x}{6}[/tex] = y
y = [tex]\frac{4x}{6}[/tex]
so f−1(x) = [tex]\frac{4x}{6}[/tex]
