Answer:

I would find the area of the circle and then find the area of the shape in the middle and then minus that from the area of the whole circle

Answer:

Step-by-step explanation:

1. Find the area of the circle. Area_c = pi * r^2

2.Find the area of the pentagon in terms of the radius Area_P =

3 sqrt(3) r^2 / 2

The answer you want is Area_shade = Area_c - area_P

Area = pi * r^2 - 3 sqrt(3)r^2/2

Area = r^2 (pi - 3 sqrt(3)/2)

The required solution to the equation 5p - 9 = 2p + 12 is p = 7, as of the given condition.

To solve the equation 5p - 9 = 2p + 12, we will follow these steps:

Combine like terms on each side of the equation:

5p - 9 = 2p + 12

Move all the terms containing "p" to one side and the constant terms to the other side. To do this, we'll subtract 2p from both sides and add 9 to both sides:

5p - 2p - 9 + 9 = 2p + 12 - 2p + 9

Simplifying both sides:

3p = 21

Now, to solve for "p," we'll divide both sides of the equation by 3:

3p/3 = 21/3

Simplifying:

p = 7

Therefore, the solution to the equation 5p - 9 = 2p + 12 is p = 7.

Answer:

the answer 6.5

........

The distance between the points R(0, 1) and S(6, 3.5) is 6.5 units after using the distance formula.

It is defined as the formula for finding the distance between two points. It has given the shortest path distance between two points.

The distance formula can be given as:

[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

It is given that:

Two points are:

R(0, 1) and S(6, 3.5)

To find the distance between points R and S we can use the distance formula.

[tex]\rm d=\sqrt{(6-0)^2+(3.5-1)^2}\\[/tex]

The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

d = √(36 + 6.25)

d = √42.25

d = 6.5 units

Thus, the distance between the points R(0, 1) and S(6, 3.5) is 6.5 units after using the distance formula.

Step-by-step explanation:

Answer:

  a = h/5

Step-by-step explanation:

If you had the equation ...

  10 = 5a

and you wanted to find the value of the variable, you would divide by its coefficient:

  10/5 = (5a)/5

  2 = a

__

Here, we have replaced '10' with 'h'. The same (single) step applies: divide by the coefficient of 'a'.

  h = 5a

  h/5 = a

To put this in "a = " form, swap the sides of the equal sign:

  a = h/5

_____

Literal equations just use different symbols (h instead of 10, here). The operations are the same.

Answer:

A = 19.1°

B = 95.5°

C = 65.4°

Step-by-step explanation:

B = 5A

C = 4A-11

We know that a triangle has a total of 180° so:

180 = A + B + C

Which can be written as:

180 = A + (5A) + (4A - 11)

180 = 10A - 11

10A = 191

A = 19.1°

With A, we can work out B and C:

B = 5(19.1)

B = 95.5°

C = 4(19.1) - 11

C = 76.4 - 11

C = 65.4°

The statement "If x = -2, then 2x = -4" can be demonstrated using the Multiplication Property of Equality.

Option C is the correct answer.

We have,

The Multiplication Property of Equality states that if you multiply both sides of an equation by the same non-zero number, the equality still holds true.

In this case, x = -2.

Multiply both sides of the equation by 2,

2x = 2(-2) = -4

Thus,

The statement "If x = -2, then 2x = -4" can be demonstrated using the Multiplication Property of Equality.

Answer: hardcover books x=11 and paperbacks y=4

Step-by-step explanation:

14x+20y=234

15x+9y=201

Multiply the top equation by 9 and the bottom equation by 20 so the outcome of both equations would be 126x+180y=2106 and 300x+180y=4020 then you subtract the two equations once you do that you get 174x=1914, and the y variable cancels out, once you divide 174 from 1914 you get 11x. So the answer for how much hardcover books cost is 11 dollars. Now we have to find the y variable which we can just plug in 11 (x) into the equation. So 15(11)+9y=201 we get 165+9y=201, subtract 165 from both sides and we get 9y=36 and divide 9 from both sides and we get 4 so y=4 the cost of paperbacks are 4 dollars

Answer:

The slope of a line characterizes the direction of a line.

Step-by-step explanation:

To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points. also You can determine the slope of a line from its graph by looking at the rise and run. One characteristic of a line is that its slope is constant all the way along it. So, you can choose any 2 points along the graph of the line to figure out the slope.
