Answer:20

Step-by-step explanation:

Cause diameter equals C/3.14 so that means to divide it

Answer: Decompose means the opposite, to take apart

Step-by-step explanation: In this lesson, the words composition and decomposition are used to describe how irregular figures can be separated into triangles and other polygons. The area of these parts can then be added together to calculate the area of the whole figure.

Answer:

b

Step-by-step explanation:

Answer:

let first equation be  y=x^2-14x+23

second equation be y=-3x+5

now substitute the vale of y in equation second

y=-3x+5

x^2-14x+23=-3x+5

x^2-14x+3x=5-23

x^2-11x=-18

x^2-11x+18=0

x^2-(9+2)x+18=0

x^2-9x-2x+18=0

x(x-9)-2(x-9)=0

(x-2)(x-9)=0

either x-2=0                                        Or, x-9=0

x-2=0

x=0+2

x=2

x-9=0

x=0+9

x=9

therefore x=2,9

Answer:

(2, - 1 ) and (9, - 22 )

Step-by-step explanation:

Given the 2 equations

y = x² - 14x + 23 → (1)

y = - 3x + 5 → (2)

Substitute y = x² - 14x + 23 into (2)

x² - 14x + 23 = - 3x + 5 ( subtract - 3x + 5 from both sides )

x² - 11x + 18 = 0 ← in standard form

(x - 2)(x - 9) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 2 = 0 ⇒ x = 2

x - 9 = 0 ⇒ x = 9

Substitute these values into (2) for corresponding values of y

x = 2 : y = - 3(2) + 5 = - 6 + 5 = - 1 ⇒ (2, - 1 )

x = 9 : y = - 3(9) + 5 = - 27 + 5 = - 22 ⇒ (9, - 22 )

Step-by-step explanation:

diameter of cylinder is 48m

radius= diameter/2

Answer:

24 meters

Step-by-step explanation:

1. Radius is half of a diameter

2. d = 48 meters

3. r = d/2 = 48/2 = 24 meters

Answer:

the domain of y = x is all real numbers.

Answer:

40079 Km

Step-by-step explanation:

La circunferencia de la tierra está dada por;

C = 2πR

Dónde;

R = radio de la tierra

Tenga en cuenta que;

R = D / 2

Por eso;

C = 2πD / 2

C = πD

C = 3.412 * 12756 kilómetros

C = 40079 Km

Answer:

I think you need to combine the equations, which would end with 26x - 2, and to solve for x just isolate it by adding to the other side which would look like 26x = 2

Then divide 26 on both sides, 26x/26 = 2/26

You should end with x = 1/13

Answer:

I think that number one is 26, two is -4, and three is -4

Step-by-step explanation:

To solve for number one replace 8 with (x) so 3(8) + 2. 3 x 8 = 24 and 24+2 = 26

Numbers 2 and 3 appear to be the same problem so just do 3(-2) + 2 (Because you replace the number with the x) 3(-2) = -6 + 2 = -4!

I hope that helped!

Answer:

3 hours

Step-by-step explanation:

3x75= 225   so you add 225 to 220 and then you get 425    so for every 3 hours he charges 75 dollars

Step-by-step explanation:

Let x = # of hours work done on the car

The inequality can written as

425 =< 75x + 200

where 425 represents the minimum cost for Hudson and 75 is the repair rate per hour charged by the mechanic. Solving this inequality, we find that

225 =< 75x

or

x >= 3

This means that the mechanic will take at least 3 hrs to work on his car.

Answer: 195,944 bicycles

Step-by-step explanation:

First find the number of bicycles sold in August.

August sales - July sales - 9,152

= 61,753 - 9,152

= 52,601 bicycles

The number of bicycles sold in 3 months is:

= June sales + July + August ,

= 81,590 + 61,753 + 52,601

= 195,944 bicycles

Answer:

Total Area = 236.715 sq ft

Step-by-step explanation:

this is a composite figure made up of a circle and a rectangle; find the area of each and then add them together

A(circle) = πr²

= π(7.5²)

= 176.715

A(rectangle) = 15(4) which is 60

Total Area = 236.715 sq ft

Answer:

C:15/36 + 6/36 + 1/36 + 1/36

Step-by-step explanation:

The expression below shows two fractions being added. 7/12 + 1/18

7/12 + 1/18

Lowest Common Denominator = 36

3 × 7 + 2 × 1/36 = 21 + 2/36

= 23/36

We solve the given options to find the correct answer

A:5/6 + 2/6 + 1/6 + 1/6 +1/6

= Lowest common denominator = 6

= 5 + 2 + 1 + 1 + 1/6 = 10/6 = 1 4/6 = 1 2/3

Option A is wrong

B: 5/30 + 1/30 + 1/30 + 1/30

Lowest common denominator = 30

5 + 1 + 1 + 1/30 = 8/30 = 4/15

Option B is wrong

C:15/36 + 6/36 + 1/36 + 1/36

Lowest common denominator = 36

15 + 6 + 1 + 1/36 = 23/36

Option C is correct

D:30/72 + 12/72 + 2/72 + 1/72

Lowest Common Denominator = 72

30 + 12 + 2 + 1/72

= 45/72

= 5/8

Option D is wrong.

Therefore, the correct answer is Option C

Answer:c

Step-by-step explanation:the answer is c

Answer:

It is a square.

Background:

With this, lets find the distance between each of the shape's points, in order to find which shape it is.

Here's the distance formula, its a bit overkill for what you're doing right now, but it may help you with questions later on.

d=√(x2​−x1​)2+(y2​−y1​)2

Process:

​So with this, compare the distance between each of the points. With Point A, it is (3, 6) with Point B it is (3,3). The change between these two points is down 3.

Next, with Point B (3,3) and Point C (6,3). The change between these two points is right 3.

Then, with Point C (6,3) and Point D (6,6). The change between these two points is up 3.

Last, with Point D (6,6) and Point A (3,6). The change between these two points is left 3.

Reasoning:

From this, we can see that all of the distance lengths are 3 units and that each of them create 90 degree angle turns*.

*You can find this by noting that the total amount of a rotation is 360 degrees, so when you change walking from up to the right, you are turning 90 degrees to do so.

Answer:

With this information in mind, it can be named a square given the definition of square:

"A regular quadrilateral, which means that it has four equal sides and four equal angles."
