Answer:
radius: 3 units <----> Circumference: 18.84 units
Diameter: 12 units <----> Circumference: 37.68 units
Diameter: 36 units <----> Circumference: 113.04 units
Radios: 5 unites <----> Circumference: 31.4 units
Step-by-step explanation:
How I got the answers for the radiuses:
3 (this is only half the diameter so if you do 3 x 2 you will get the diameter.)
3 x 2 = 6
C = pi x d
C = 3.14 x 6
C = 18.84 [this is the first radios]
5 (this is only half the diameter so if you do 5 x 2 you will get the diameter.)
5 x 2 = 10
C = pi x d
C = 3.14 x 10
C = 31.4 [this is the second radios]
How I got the diameters:
12 (this is the full diameter so we do not have to multiply it by 2)
C = pi x d
C = 3.14 x 12
C = 37.68 [this is the first Diameter]
36 (this is the full diameter so we do not have to multiply it by 2)
C = pi x d
C = 3.14 x 36
C = 113.04 [this is the second Diameter]

“Each set below has 3 expressions. There is ONE expression in EACH set that DOES NOT BELONG. Try to find the expression that does not belong in EACH SET and EXPLAIN WHY!” -please help im behind because I was online schooled at a bad school so now I’m at a different school and my tutor is sick.
Set 1: 3(x + 2) // 3x +6 // 3(2x)
Set 2: 1/2 (-4x) // 1/2 (2x - 6) // x - 3
Set 3: 24x + 8y // 2 (12x + 4y) // 8(3x + y)
Answer:
Set 1: 3(2x)
Set 2: 1/2 (-4x)
Set 3: 2 (12x + 4y)
Step-by-step explanation:
Set 1: 3(x+2) and 3x+6 are the same//3(x+2) =3x+6
Set 2: 1/2 (2x - 6) and x - 3 are the same//1/2 (2x - 6) = x-3
Set 3: 24x + 8y and 8(3x + y) are the same//2x+8y = 8(3x + y)

An oblique cylinder has a radius of 16 meters and a volume of 5,120(pi) cubic meters. Use Cavalieri’s Principle to solve for the height of the solid.
20 meters
25 meters
50 meters
250 meters
Answer: 20 meters
Step-by-step explanation:
We are told that an oblique cylinder has a radius of 16 meters and a volume of 5,120 pi cubic meters. We will use volume of oblique cylinder to find the height of our given cylinder. volume of a oblique cylinder= πr²hUpon substituting our given values in above formula we will get,5,120π m³ = π ( 16 m² × h )
5,120π m³ = π × 256 m² × h
Let us divide both sides of our equation by 100 pi.Therefore, height of our given oblique cylinder is 20 meters.

Mixed number is the combination of the whole number and the fraction number. The whole and the part of the whole combined can be expressed as a mixed numbers. the result of the division of the two mixed number is [tex]3\dfrac{3}{16}[/tex].

The mixed numbers given is the problem are [tex]8\dfrac{1}{3} [/tex] and [tex]2\dfrac{2}{3} [/tex]
Mixed numberMixed number is the combination of the whole number and the fraction number. The whole and the part of the whole combined can be expressed as a mixed numbers.
Now the given mixed number has to be divided. This number can be divided by converting into the proper fraction numbers. Let I is the result when the two numbers are divided. Thus,
[tex]x=8\dfrac{1}{2} \div 2\dfrac{2}{3} \\ [/tex]
To solve this convert the mixed numbers into the fraction number. For this multiply the denominator to the whole number and then add in the numerator. Thus,
[tex]x=\dfrac{16+1}{2} \div \dfrac{6+2}{3} \\ x=\dfrac{17}{2} \div \dfrac{8}{3} \\ [/tex]
Convert the divide sign into the multiply sign by changing the numerator to the denominator of one of the fraction.
[tex]x=\dfrac{17}{2}\times \dfrac{3}{8} \\ x=\dfrac{51}{16}\\[/tex]
As 16 can divide the number 51 in 3 times with reminder 3. Thus the mixed number for the above fraction can be written as,
[tex]x=3\dfrac{3}{16}[/tex]
Thus the result of the division of the two mixed number is [tex]3\dfrac{3}{16}[/tex].

Aiden earned $50 in interest in six
months. If his savings account has a
rate of 5%, how much did Aiden
start with in his account?
9514 1404 393
Answer:
$2000
Step-by-step explanation:
The amount of interest is given by the formula ...
I = Prt
where P is the principal invested, r is the annual rate, and t is the number of years. Here, we want to find P when I = 50, r = 0.05, and t = 1/2.
50 = P(0.05)(1/2)
P = 50/(0.05·1/2) = 2000
Alden started with $2000 in his account.
For 15 points.Explain, in your own words, the steps necessary to solve a system of equations
using the substitution method.
First, what is an equation?
➳ A mathematical statement which shows that two algebraic expressions are equal is called and equation.
Or, LHS = RHS
Example:- 3x - 5 = x + 8
An equation is said to be a linear equation if it contains only one variable (literal) with highest power 1.
_______________________
Solving an equation:-
To solve the equation x + 5 = 7 means to find the value of an unknown algebraic quantity used in the equation.
Example:-
To solve the equation x + 5 = 7 means to find the value of x.To solve the equation 3y + 2 = 9 means to find the value of y.To solve the equation [tex]\sf \dfrac{2a}{3} + 4 = 10[/tex] means to find the value of a ⠀⠀⠀⠀⠀⠀and so on!⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
★ Rules for solving an equation by the substitution method:-
Rule ❶
If x = 2, the value of the expression 3x + 2 = 3 × 2 + 2 = 6 + 2 = 8
Rule ❷
If x = 0, the value of the expression 3x + 2 = 3 × 0 + 2 = 0 + 2 = 2
Rule ❸
If x = -2, the value of the expression 3x + 2 = 3 × -2 + 2 = -6 + 2 = -4
Now consider the algebraic expression 5x - 2y
This expression consists of variables x and y.
Now if :-
x = 3 and y = 2, 5x - 2y = 5 × 3 2 × 2 = 15 - 4 = 11x = 8 and y = 5, 5x - 2y = 5 × 8 - 2 × 5 = 40 - 10 = 30⠀⠀⠀⠀⠀⠀⠀⠀
The process of finding the value of an algebraic expression by substituting the given value of its variable is called substitution.⠀⠀

Answer:
b
Step-by-step explanation:
The slope of b is 5.5 whereas the slope for the other three graphs are 5, so B is different from the rest.
A. (4, 0.8), so by rise over run, the slope is 4/0.8=5.
B. (55, 10), so 55/10=5.5.
C. (20, 4), so 20/4=5.
D. (50, 10), so 50/10=5.
Since B is the only graph with a slope of 5.5 and the other graphs have a slope of 5, the answer is B.
Wesley has a baseball sticker with a radius of 2.3 centimeters. Determine the circumference of his baseball sticker to the nearest tenth of a centimeter.
Answer:
14.4 centimeters
Step-by-step explanation:
The formula for circumference is: [tex]2\pi r[/tex]. In this case, the r (radius) is 2.3. Multiply it by 2 to get the diameter or 4.6. Then multiply 4.6 x [tex]\pi[/tex] (pi) to get 14.444. This rounded to the nearest tenth of a centimeter is 14.4.
Note:
I used 3.14 for [tex]\pi[/tex] (pi).

Callie posted a cute cat video on a popular website. On the first day after she posted the video, the video had 5 views. On the second day, it had 15 views. On the third day, it had 45 views, and on the fourth day, it had 135 views.
A. How many views would you expect the video to have after 5 days? Explain how you found your answer.
B. Which type of reasoning did you use to solve this problem, deductive or inductive? (2 points)
Answer:
(A) 5th day: 405 views
(B) inductive
Step-by-step explanation:
Each day the views get multiplied by 3.
Answer:
A. I would expect the video to have 405 views after day 5. There is a pattern of the number being multiplied by 3.
B. Deductive reasoning
Step-by-step explanation:
(This is really going to explain BOTH questions at the same time)
Looking that the problem, the number of views keep going up. There is a multiplier behind this, we just don't know WHAT multiplier it would be. To find that out, divide 1 value by the one before it. I'll do 135 divided by 45 as an example. That would equal three. Now we know the multiplier is 3. So, now we need to multiply 135 by 3 to get 405 views after five days.

Step-by-step explanation:
Answer: a + 3b
Step-by-step explanation:
Okay, so...
7(3a - 2b) = 7(3a) - 7(2b) ... distributive property
21a - 14b
5(3b - 4a) = 5(3b) - 5(4a) ... distributive property
15b - 20a
(21a - 14b) + (15b - 20a) = 21a -12b + 15b - 20a =
