What is the equation for a circle?

Answers

Answer 1

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.

Answer 2

Answer with step-by-step explanation:

1. Circum = π × Diameter

2. A straight line passing from side to side through the center of a circle

3. A straight line from the center to the circumference of a circle or sphere.

4. Area = (π × Radius)^2

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

Answers

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.

What would be your next step?
14p - 8 = 22 + 20p
-8 = 22 + 6p

Answers

to subtract 22 from both sides, then the 6p after! hope that helped :))

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.

Answers

In order to solve this problem, we must first p it all variables on one side and all numbers on the other.

7y-8=6y+1

We subtract 6y from both sides to cancel it out on the right and have it on the left.

Y-8=1

Now, we put the numbers on the opposing side.

Y=9

We receive the answer Y=9

To check it, we can plug or input 9 into both equations.

7(9)-8=6(9)+1
63-8=54+1
55=55

Now that we know they are equal, we can conclude that the answer is 9.

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%.

Answers

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

Answers

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.

Answer:

18 square feet
