Answer:
Cone Volume = (PI * radius^2 * height) / 3
Cone Volume = (PI * 2^2 * 9) / 3
Cone Volume = 113.0973355292 / 3
Cone Volume = 37.7 cubic inches

Two towns tracked the attendance at their summer fairs in 2016 and 2017. The data for each town and year is shown below. Year Ogdenville North Haverbrook 2016 960 500 2017 1008 540 What was the difference between the percent increases for each town from 2016 to 2017?
Answer:
48 and 5%; 40 and 8%
Step-by-step explanation:
The computation of the difference between the percentage increase for each town from 2016 to 2017 is given below:
Year Ogdenville North Haverbrook
2016 960 500
2017 1008 540
So here the difference would be
For 2016 to 2017
= 1008 - 960
= 48
The percentage increase is
= 48 ÷ 960
= 5%
And,
= 540 - 500
= 40
And, the percentage increase is
= 40 ÷ 500
= 8%

Which is equivalent to (4 x y minus 3 z) squared, and what type of special product is it
question answer choices are:
A. 16 x squared y squared + 9 z squared, the difference of squares
B. 16 x squared y squared + 9 z squared, a perfect square trinomial
C. 16 x squared y squared minus 24 x y z + 9 z squared, the difference of squares
D. 16 x squared y squared minus 24 x y z + 9 z squared, a perfect square trinomial
Answer:
The answer is option D
Step-by-step explanation:
When factored out option C and D are the same but it is a perfect square, not the difference of squares.
Option (D) 16 x squared y squared minus 24 x y z + 9 z squared, a perfect square trinomial is the correct answer.
What is an algebraic expression?An expression which is made up of variables and constants, along with algebraic operations (addition, subtraction, etc.). Algebraic expressions include at least one variable and at least one operation.
For the given situation,
The expression is (4xy-3z)^2.
This expression can be expand by using the formula,
[tex](a-b)^{2} = a^{2} -2ab+b^{2}[/tex]
Here, a = 4xy and b = 3z
⇒ [tex](4xy)^{2} -2(4xy)(3z)+(3z)^{2}[/tex]
⇒ [tex]16x^{2} y^{2} -24xyz+9z^{2}[/tex]
Hence we can conclude that option (D) 16 x squared y squared minus 24 x y z + 9 z squared, a perfect square trinomial is the correct answer.

Help plssss lolllllll
Answer:
8
Step-by-step explanation:
you want to set it up like this
8/20 and 6/2x-1
then you cross multiply
so 8(2x-1) = 16x-8
and 20*6 = 120
then you do 120= 16x-8
add 8 to both sides (you want x by it's self so to get rid of a -8 you have to add 8)
128= 16x
(divide both sides by 16)
128/16= 8
8=x

If f(x) = 5x – 2 and g(x) = x+1, find (f = g)(x).
OA. 5x - x-3
B. 5x2 +1
O C. 5x® - X-1
D. 5x4 - 2
Answer: Choice A) 5x^3 - x - 3
=================================================
Work Shown:
We subtract the two functions like so
(f - g)(x) = f(x) - g(x)
(f - g)(x) = ( 5x^3-2 ) - ( x+1 )
(f - g)(x) = 5x^3 - 2 - x - 1
(f - g)(x) = 5x^3 - x - 3 ..... choice A
Note: be sure to remember to distribute the negative to every term inside (x+1), and not just to the x only.

Step-by-step explanation:
The rule is that each time you add by 7, like in the first 2. 4+7=11 and 7+7=14
Select all of the following that can be a counterexample for the statement below.
If x is an integer, then x + 2 > 7.
I can't see pictures, but I'm assuming you want it solved.
x+2>7.
Cancel out the 2 by subtracting 2 from both sides.
x+2>7
-2 -2
x>5
So the inequality is x>5.

This is proportional, true or false? (Proportional means it has an equivalent ratio/constant rate of change/the same rate) (True=yes, it's proportional, false means it is not proportional) y = 12x
Answer:
Yes/True
Step-by-step explanation:
The given expression is :
y = 12 x
We know that, Proportional means it has an equivalent ratio / constant rate of change / the same rate.
Here,
y ∝ x
12 is the constant of proportionality
Hence, the given expression is proportional.

Solve for x if 2(x - 2) = 26
A) x=25
B) x=8
C) x=15
D) c=30
Answer:
The answer is C x=15
Step-by-step explanation:
Simplify both sides of the equation.
2(x−2)=26
(2)(x)+(2)(−2)=26(Distribute)
2x+−4=26
2x−4=26
Add 4 to both sides.
2x−4+4=26+4
2x=30
Divide both sides by 2.
2x /2 = 30/ 2
x=15
Answer:
x= 15
