Answer:
24 pi
Step-by-step explanation:
you basically need to work out the circumeference
circumference=pi times diameter
if the radius is 12, the diameter is 24
so it would be 24 pi

5-2=3
Just do it the other way to find the answer!
I hope this helps!
Answer: x = 3
Step-by-step explanation:
we subtract 2 from both sides, in order to get the variable by itself.
x + 2 (- 2) = 5 (- 2)
x = 3

Using Joe’s triangle what is the slope of the graph
Answer:
The slope is 2.
Step-by-step explanation:
You can take the second plotted point of the graph. (2,4)
Since slope is y/x, the equation is 4/2.
4/2=2
If a sweatshirt normally costs $40 but it is
marked down 20%. How much would it cost?
Answer:
$32
Step-by-step explanation:
First, find 20% of 40.
20% as a decimal is 0.20 (20/100)
0.20 x 40 = 8
Now, subtract 8 from the original price.
40 - 8 = 32
Answer:
$32
40 decrease 40%
40 x (1-20%) = 40 x (1-0.2) =32

Answer:
70x
Step-by-step explanation:
8x8 = 64x then +6x = 70x
Answer:
[tex]2x(4x+3)[/tex]
Step-by-step explanation:
The first thing to factorising this expression is to find the greatest common factor (GCF). For 8x² and 6x the gcf is 2x. So now we divide the 8x² and 6x by the 2x. Which comes out to 4x and 3, these will be inside the parentheses.
So it'll factorise to [tex]2x(4x+3)[/tex] and remember when we are dividing with exponents we subtract the exponents. So [tex]\frac{8x^2}{2x}[/tex] we will divide the coefficients together that'll be 4 and now for the exponents the 2 on the x² minus the 1 on the x will equal 1 so it'll be just x we don't place a one or anything.

Which of the following is equivalent to the image below
A: 6
B: 8
C: 12
D: 64
Answer: The answer is 8
Step-by-step explanation: first you solve 16 to the 1.5 power (3/2=1.5) and that gives you 64. Then 64 to the .5 power (1/2=.5) and that gives you 8.

Esma and Hunter were trying to solve the equation:
? + 8x = 22 - 8
They both agreed they should first subtract 2x and add 8 to both sides and rewrite the equation as
2? + 6x + 8 = 0.
Then Esma said, "I can complete the square. I can add 1 to both sides to rewrite this equation as
32 +63 +9 = 1, factor, and solve using square roots."
Hunter said, "I'll factor the left-hand side of the equation as (+ + 2)(x + 4) and solve using the zero
product property."
Whose solution strategy would work?
Choose 1 answer.
A. Only Esma's
B. Only Hunter's
C. Both
D. Neither
Answer: both esmas and hunters strategies work

Step-by-step explanation:
solving systems of linear inequalities
Answer:
YES. (2, 7) is a solution of the system.
Step-by-step explanation:
System of linear inequalities has been given as,
y ≥ -x + 1 --------(1)
y < 4x + 2 ------(2)
If (2, 7) is a solution of the given system of inequalities, it will satisfy both the inequalities.
By substituting the coordinates of point (2, 7) in inequality (1),
7 ≥ -2 + 1
7 ≥ -1
True.
By substituting the coordinates of point (2, 7) in inequality (2),
7 < 4(2) + 1
7 < 9
True.
Therefore, point (2, 7) lie in the solution area of system of inequalities.
YES. (2, 7) is a solution of the system.

I am a student teacher at my highschool
if 72 is 40% what is 100%?
Answer:
180
Step-by-step explanation:
If 40% = 72, 100% can be found like so:
40% = 72
100% = [tex]\frac{100}{1}[/tex] * [tex]\frac{72}{40}[/tex]
You can reduce 40 and 100 by 20 (or probably more, but I'll use 20)
So now we have:
[tex]\frac{50}{1}[/tex] * [tex]\frac{72}{20}[/tex] = [tex]\frac{3600}{20}[/tex]Divide, and you get 180.
To check, we can find 40% of 180.

2^2 = 4
4^2 = 16
D
2^2=4
2^4 = 16
Answer:
A and D
Step-by-step explanation:
A.) plug in 2 first then 4
2^2= 4 and 4^2= 16 so it applies
B.) does NOT apply bc 2+6=8 and not f(2)=4 and also does not equal to 16
4+6=10
C.) does NOT apply bc 4(2)+2=10 and not to 4 and also does not equal to 16; 4(4)+2=18
D.) does apply 2^2=4 and 2^4=16
Which of the following best describes the graph below?
Answer:
The correct option is;
A. It is a one-to-one function
Step-by-step explanation:
A function f(x), is a one to one function when each value in the range is given by each unique value in the domain such that each "x" value produces a unique "y" value.
The given graph has a domain of -2 ≤ x < ∞
Within the domain plotted in the graph, all lines with equation "x" = -2, -1, 0..., 4, 5 crosses the graph only once, therefore, for each value of "x", there is only one value of "y", which gives the relationship between the "x" and "y" values as one to one function
Write an equation of the line that passes through (1, 2) and is parallel to the line y = -52 +4.

A stuffy normally costs $12, but this week it is on sale for $9. What is the Percent of Change on the stuffy?
Answer: 25%
Step-by-step explanation:
From the question, we are told that a stuffy normally costs $12, but that this week it is on sale for $9.
The Percent of Change on the stuffy will be calculated as:
= Change / Normal cost × 100
= (12 -9) / 12 × 100
= 3/12 × 100
= 1/4 × 100
= 25%

Jenna has already cycled 8 kilometers this year,plus she plans to cycle 2 kilometers during each trip to work.Write an equation that shows the relationship between the number of trips to work t and the total distance cycled d.
Answer:
[tex]d = 8 + 2t[/tex]
Step-by-step explanation:
Given
[tex]Rate = 2km/trip[/tex]
[tex]Base\ Cycle = 8km[/tex]
[tex]d = total\ distance[/tex]
[tex]t = cycles[/tex]
Required
Determine the expression for this scenario
The expression can be derived from:
[tex]Total\ Distance = Base\ Cycle + Rate * Cycles[/tex]
Substitute d for Total Distance and t for cycles
[tex]d = Base\ Cycle + Rate * t[/tex]
Substitute values for Base Cycle and Rate
[tex]d = 8 + 2* t[/tex]
[tex]d = 8 + 2t[/tex]
find the value of x..
Answer:
B x = 7
Step-by-step explanation:
You know based on the ratio that it's being scaled by 4 times because the one side 4 is 16 in the bigger pentagon.
So if you go the side that matches the one you need to solve, it's 2.5.
2.5 times 4 = 10 so that bigger pentagon side should equal 10.
The equation x-3 = 10
which means x is 7
