What type of line segment is represented by the dotted line.
Please help me on this question, it is for geometry.

Answer:

Step-by-step explanation:

outer area=

first need to find the circumference of outer diameter

= π×4.8

= 15.079644.... cm

to find the outer curved area you would then do

= 77×15.079644

(ii) =1161.13264 cm²

inner curve area

circumference= π×4

=12.5663706.... cm

77×12.5663706

(i) =967.610537 cm²

total surface area=

as the outer and inner curved areas are already found only the top and bottom surfaces need to be

= area of larger circle

=π×4.8²

=72.382294.... cm²

smaller circle

=π×4²

=50.2654824.... cm²

72.382...-50.265

=22.1168116 x 2

=44.2336232 cm²

total surface area

(iii)= 2172.9768 cm²

(round this to however many decimals you need)

I hope this is understandable and useful!

We conclude that the solution is:

Step-by-step explanation:

Given the equation

[tex]12\left(x\:+\:8\right)\:=\:11x\:-\:5[/tex]

Expand 12(x + 8):  12x + 96

[tex]12x+96=11x-5[/tex]

Subtract 96 from both sides

[tex]12x+96-96=11x-5-96[/tex]

Simplify

[tex]12x=11x-101[/tex]

Subtract 11x from both sides

[tex]12x-11x=11x-101-11x[/tex]

Simplify

[tex]x=-101[/tex]

Therefore, we conclude that the solution is:

Answer: 60 m

Step-by-step explanation:

The park is said to be square which means that all of its sides are equal.

If the fence is supposed to be put around the park, it is an indirect question asking for the perimeter of the square.

Perimeter of a square:

Answer:

  (x, y) = (-8.625, -63)

Step-by-step explanation:

Substitute for y.

  -63 = 8x +6

  -69 = 8x . . . . . subtract 6

  -69/8 = x = -8.625

The solution is (x, y) = (-8.625, -63).

g(f(x)) = -x^2 + x - 15

Step-by-step explanation:

g(f(x^2 - x + 11) = -1 * (x^2 - x + 11) - 4 = -x^2 + x - 11 - 4 = -x^2 + x - 15

Answer:

3x+2y-8=0

Step-by-step explanation:

The equation 3x+2y=8 in general form is 3x + 2y - 8 = 0 respectively.

A numerical expression is an algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.

We are given that  the equation 3x+2y=8.

The equation of straight line is written as y = mx + c

3x+2y=8.

2y = 8 - 3x

y = 8/2 - 3/2x

y = 4 - 3x/2

Hence, the general form is 3x + 2y - 8 = 0.

Answer:

Opportunity sampling is also known as convenience and it can be defined as a sampling technique which typically involves the process of selecting participants from a population of interest (target group) to take part in a research study.

Step-by-step explanation:

In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.

There are various types of sampling used by researchers and these are;

1. Random sampling.

2. Systematic sampling.

3. Stratified sampling.

4. Cluster sampling.

5. Opportunity or convenience sampling.

Opportunity sampling is also known as convenience and it can be defined as a sampling technique which typically involves the process of selecting participants from a population of interest (target group) to take part in a research study.

This ultimately implies that, an opportunity sampling is a non-probability sampling in which a researcher select participants based on their availability for the study.

For example, John a psychologist standing on the street requesting that passersby join in his research study.

Answer:

43.98

Step-by-step explanation:

You have to multiply 14 times Pi which is approximately 3.14 and then round to the nearest ten.

Step-by-step explanation:

First, we need to put this standard form into slope-intercept form

To do this you need to move the "y" to all by itself

-25x+25x-20y=100-25x

-20y=100-25x

y=5/4x-5

Answer:

y=5/4x-5

The slope is-5/4 and the -intercept is (0,5)

Locating the y-intercept on a graph requires knowing the value of y at x=0. This is where the graph intersects the y-axis.

25x−20y=100

20y = 100 + 25x

20y=100+25x

y = [tex]5 + \frac{5}{4}[/tex]

She concluded that the slope is   [tex]\frac{5}{4}[/tex]

​and the y-intercept is (0,5).

y = mx + b where m is the slope and b is the y-intercept. So, the slope is 5/4 and the y-intercept is -5.

The slope is-5/4 and the -intercept is (0,5)

Answer:

8

Step-by-step explanation:

78 - 6 = 72 (Since the number falls short by six)

72 ÷ 9 = 8 (Number times 9 that equals 72)

Step-by-step explanation:

y = 4x+3

2x-3y = 21

2x -3(4x+3) = 21

2x -12x -9 = 21

-10x = 21 + 9

-10x = 30

x = -3

Answer:

14. She deposited $15.50 into her bank.

15. The width would be 900.

Step-by-step explanation:

14. 245.60 + x = 261.10

x = 15.50

245.60 + 15.50 = 261.10.

She deposited $15.50 into her bank and resulted in her new bank balance appearing as $261.10.

15. Width is 900 cm

Length is 12 cm.

A = L X W = 108

A = L * 3/4L

108 = 3/4L2

Divide both sides by 3/4: multiply both sides by the inverse of 3/4 or 4/3.  

(4/3)*108 = L2

144 = L2

√144 = L

12 = L

W = 3/4*12

W = 9

Before we finish:

A = 108 = 9 x 12 = 108

W/L = 3/4 = 9/12 = 3/4

The width of the rectangle would be 3/4.
