DE is the perpendicular bisector of AC. Find AC.

Answer:

Slope in fraction form = 5/2

Slope in decimal form = 2.5

========================================================

Work Shown:

m = (y2-y1)/(x2-x1)

m = (-5-10)/(-2-4)

m = (-15)/(-6)

m = (-3*5)/(-3*2)

m = 5/2 slope in fraction form

m = 2.5 slope in decimal form

-----------------

Explanation:

The first step is the slope formula where (x1,y1) and (x2,y2) are the two points the line goes through.

I used (x1,y1) = (4,10) and (x2,y2) = (-2,-5)

The slope formula basically says "subtract the y values, then subtract the x values in the same order. Then divide the two differences".

Or you can think of it as

slope = rise/run

rise = y2-y1 = change in y

run = x2-x1 = change in x

Answer:

24m^2

Step-by-step explanation:

to get the length, we have to follow this equation:

2W + 2L = P

2(4) + 2L = 20

8 + 2L = 20

8 + 2(6) = 20

to get the area from this information, we have to follow this equation:

A = W • L

A = 4 • 6

A = 24m^2

Answer:

y - 6 = -(x - 5)

Step-by-step explanation:

Start with the general point-slope form y - k = m(x - h).

Here m = -1, h = 5 and k = 6, and so, after substitutions, we have:

y - 6 = -(x - 5)

Answer:

8595

Step-by-step explanation:

This question can be solved in 2 ways

1. the same number of bottles were sold for 3 days. So, the number of bottles sold  can be multiplied by 3

2,865 x 3 = 8595

2. the bottles sold on Friday, Saturday and Sunday are added together

2,865 + 2,865 + 2,865 =  8595

Answer:

-3

Step-by-step explanation:

use the equation y = mx + b where m is the slope and b is the y-intercept so just plug in what you know. y = 2/3x + 2 then solve the equation for x . To do that, just put y = 0 so then it would be -2 = 2/3x then -2/ 2/3 = x and -2 divided by 2/3 would be -3

Answer:

The third one

Step-by-step explanation:

To find the middle you have to put the numbers from least to greatest. You have 27 and 31, add them together you get 58. Now you divide 58 into 2 and answer is 29. (This one is to figure out the median)

7) x = 12 and the side lengths are all 23

Answer:

yes, the following is a function

Answer:

The Richter scale measures the largest wiggle (amplitude) on the recording, but other magnitude scales measure different parts of the earthquake. The USGS currently reports earthquake magnitudes using the Moment Magnitude scale, though many other magnitudes are calculated for research and comparison purposes.

Answer:the other point at x=-1 is (-1,0)

the other point at x=-1 is (-1,0)this fails the vertical line test so it is a relation not a function

Answer:

b = ft

Perimeter = 42.6 ft

Step-by-step explanation:

We know that the area is equal to length times width, so in our case

Area = b x a

Since we know the value of the area and the width we can find the length by doing the following...

Area = b x a

b = Area / a

b = 111.6 / 9.3

b = 12 ft

Perimeter = 2b + 2a

Perimeter = 2(12) + 2(9.3)

Perimeter = 42.6 ft

Answer:

Sample

Step-by-step explanation:

Just took on Edge.

Sample describes the number 58.2 in the given problem.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

A sample is a subset of individuals or items selected from a population, and statistics are values calculated from a sample.

As given, the governor of Florida randomly selected 500 Florida residents and determined their mean age to be 58.2 years.

This value is a sample statistic because it is calculated from a sample of individuals and is used to estimate a population parameter.

The number 58.2 represents a sample statistic.

Hence,  sample describes the number 58.2 in the given problem.

Answer:

no

Step-by-step explanation:

the slope is the angle of the line. to make this easier, I normally imagine rise/run. rise being the y axis and run being the x axis. if we change -3 to a fraction, it is -3/1. this basically means that from any given point, you go down 3 units, and over 1.

replace the (-3,0) point with a (3,1) point and it should be fixed.

Answer: 5966cm³

Step-by-step explanation:

The volume of a cylinder is calculated using the formula:

Volume = πr²h

where, π = 3.14

radius = 10cm

Height = 19cm

Volume = πr²h

= 3.14 × 10² × 19

= 3.14 × 100 × 19

= 5966.00cm³

Answer: 2^2 * 3^3

Step-by-step explanation: In this problem, you are only transferring each factor into an exponent. Since there are two factors of two and three factors of three, the answer would be two squared multiplied by three cubed.

Given:

The sequence is 2, 4, 8, 16,... .

To find:

The explicit formula for the sequence and use it to find the eleventh teen in the sequence.

Solution:

We have,

2, 4, 8, 16,...

It is a GP because the ratio between two consecutive terms are same..

Here,

First term: [tex]a = 2[/tex]

Common ratio: [tex]r=\dfrac{a_2}{a_}[/tex]

[tex]r=\dfrac{4}{2}[/tex]

[tex]r=2[/tex]

The explicit formula of GP is:

[tex]a_n=ar^{n-1}[/tex]

Putting [tex]a=2,r=2[/tex], we get

[tex]a_n=2(2)^{n-1}[/tex]

Put n=11 to find the 11th term of the given sequence.

[tex]a_{11}=2(2)^{11-1}[/tex]

[tex]a_{11}=2(2)^{10}[/tex]

[tex]a_{11}=2(1024)[/tex]

[tex]a_{11}=2048[/tex]

Therefore, the correct option is D.

Using long division 1020 ÷ 156 is equal to  654.

Addition is also known as the sum, subtraction is also known as the difference, multiplication is also known as the product, and division is also known as the factor.

Given, 102024  is divided by 156​.

First, we'll take up to 1020 ÷ 156 then we'll have a reminder of two-digit and a quotient of 1 digit we will bring down the next digit and continue the process until it is completely divisible or we have a remainder than is less than 156.

1020 ÷ 156

= 654.

Answer:

1 / 18

Step-by-step explanation:

PROBABILITY OF DRAWING THE NUMBER 7 THE FIRST TIME = Number of favorable outcome / Total number of outcomes

Favorable outcome = 1

Total number of outcome (1,2,3,4,5,6,7,8,9,10) = 10

PROBABILITY OF DRAWING THE NUMBER 7 THE FIRST TIME  = 1 / 10

PROBABILITY OF DRAWING AN EVEN NUMBER THE SECOND TIME = Number of favorable outcome / Total number of outcomes

Favorable outcome (2,4,6,8,10) = 5

Total number of outcomes (1,2,3,4,5,6,8,9,10) = 9

PROBABILITY OF DRAWING AN EVEN NUMBER THE SECOND TIME = 5/9

PROBABILITY OF DRAWING THE NUMBER 7 THE FIRST TIME AND THEN DRAWING AN EVEN NUMBER = 1 / 10  * 5 / 9 = 1 / 18
