Answer:
1. 2[tex]\pi[/tex]r = C
2. The diameter is the length of the line through the center that touches two points on the edge of the circle.
3. Half of the diameter. The length of a line from one point on the edge of a circle to the center.
4. (x-h)² + (y-k)² = r² where (h,k) is the center and r is the radius.

You want to build this bookshelf. Given that a∥ b and m∠3=x and m∠2=x+30. Find the measure of ∠4, ∠5, and ∠6
m<4= ___ Degrees
m<5= ___ Degrees
m<6= ___ Degrees
Answer:
[tex]\huge\boxed{m \angle 4 = 105 \textdegree}[/tex]
[tex]\huge\boxed{m \angle 5 = 75 \textdegree}[/tex]
[tex]\huge\boxed{m \angle 6 = 105 \textdegree}[/tex]
Step-by-step explanation:
We can use basic angle relationships to find the measures of m∠4, m∠5, and m∠6.
We know that angles m∠3 and m∠2 are supplementary. This means their angle lengths add up to 180°. Since we know the expression for both, we can add them and solve for x.
[tex](x) + (x+30)=180[/tex] [tex]2x+30=180[/tex] [tex]2x=150[/tex] [tex]x = 75[/tex]So x = 75°, aka m∠3 is 75°. This means m∠2 is going to be [tex]75+30=105[/tex]°.
m∠4 is an opposite angle to m∠2. This means their angle lengths are the same. Therefore, m∠4 is 105°.
We also know that m∠3 and m∠5 are alternate interior angles, meaning their angle lengths are the same. Since m∠3 is 75°, m∠5 is also 75°.
We also know that m∠6 is a corresponding angle to m∠2. This means their angle lengths are the same. Since m∠2 is 105°, m∠6 is also 105°.

Elliott is counting the change from a class fundraiser. He has half as many quarters as nickels, and he has 7 fewer dimes than nickels. The total value of coins is $5.90. He wrote the equation 0.10 (7 minus x) + 0.5 (x) + 0.25 (one-half x) = 5.90. Which statements identify Elliott’s errors? Check all that apply.
He should have written the expression for the number of dimes as x – 7.
He should have written the coin values as 5, 10, and 25 and not as 0.5, 0.10, and 0.25.
He should have written the coin value for the nickel as 0.05.
He should have translated the scenario as value of all dimes = value of all nickels and value of all quarters = value of all nickels.
He should have written the expression for number of nickels as 2x.
Answer: He should have translated the scenario as value of all dimes = value of all

What would be your next step?
14p - 8 = 22 + 20p
-8 = 22 + 6p
The next step to solve the equation is subtracting 22 from both sides.
Thus, option (B) is correct.
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
Given equation: -8 = 22 + 6p.
1. Start by isolating the variable term, 6p, on one side of the equation.
In this case, subtracting 22 from both sides of the equation:
-8 - 22 = 22 + 6p - 22
-30 = 6p
2. Next, divide both sides of the equation by 6 to solve for p:
-30/6 = 6p/6
-5 = p
Therefore, the solution to the equation is p = -5.
Thus, option (B) is correct.

The table shows the participation in a school's debate club during the last four years.
Year 1 2 3 4
Students 14 19 25 33
Between which two years did the club see the greatest growth? By what percent did it grow?
A. The greatest growth was between years 3 and 4. The growth between those years was about 32%.
B. The greatest growth was between years 1 and 2. The growth between those years was about 5%.
C. The greatest growth was between years 3 and 4. The growth between those years was about 8%.
D. The greatest growth was between years 1 and 2. The growth between those years was about 36%.
Answer:
D
Step-by-step explanation:
19 - 14 = 5 / 14 x 100 = 35.714 > 36%
The other values by calculating the percent increase were
(from 2-3) = 31.57%
(from 3-4) = 32%
Greatest growth was between years 3 and 4. The growth between those years was about 32%.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given table is participation in a school's debate club during the last four years.
Year 1 2 3 4
Students 14 19 25 33
We need to find between which two years did the club see the greatest growth.
From year 1 and 2 the growth is increased by 5 (19-14)
year 2 and 3 the growth is increased by 6 (25-19)
year 3 and 4 the growth is increased by 8 (33-25)
So between 3 and 4 there is greatest growth.
Now let us find the percentage of the growth.
33-25/25
0.32×100
32%
Hence, greatest growth was between years 3 and 4. The growth between those years was about 32%.

The dimensions of a rectangular dining room are 18 feet by 16 feet. If a scale factor of One-fourth is used to make a scale model of the dining room, what is the area of the dining room in the scale model?
18 square feet
36 square feet
48 square feet
72 square feet
Given -
The dimensions of a rectangular dining room are 18 feet by 16 feet. i.e, length (l) = 18 feet and breadth (b) = 16 feetScale factor of One-fourth is used to make a scale model of the dining room.To find -
the area of the dining room in the scale model (A)Solution -
As we know, the area of rectangle = length of the rectangle × breadth of the rectangle
To state the dimensions of the scale model we will multiply 1/4 with the already given dimensions of a rectangular dining room. Hence, dimensions of scale model is 18/4 by 16/4.
Now,
Area = length × breadth
Area = 18/4 × 16/4 square feet
Area = 18 square feet
Therefore, the area of the dining room in the scale model (A) is 18 square feet.

18 square feet

In complete sentences explain why you can sometimes add square roots with different radicands. Give an example where you can add square roots with different radicands and an example where you cannot add square roots with different radicands.
Answer:
Just as with "regular" numbers, square roots can be added together. But you might not be able to simplify the addition all the way down to one number. Just as "you can't add apples and oranges", so also you cannot combine "unlike" radical terms. In order to be able to combine radical terms together,
those terms have to have the same radical part.
