Answer:

12.8

Step-by-step explanation:

The mean is 5.2 so,

|7 - 5.2| + |6 - 5.2| + |3 - 5.2| + |9 - 5.2| + |1 - 5.2| = 12.8

Answer:

d = 90 degrees

e = 49 degrees

f = 131 degrees

Step-by-step explanation:

angle d is 90 degrees because adjacent angles add to 180 degrees, if the adjacent angle is right it is equal to 90 degrees, 180 - 90 is 90.

angle e is 49 degrees because opposite angles are equivalent.

angle f is 131 because adjacent angles add to 180 degrees, if the adjacent angle is 49, 180 - 49 is 131.

Answer is C) (0, -15)

Answer:

Step-by-step explanation:

First, find yourself a map. Then, using two points, find both the distance on the map and the true distance. Next, you divide the true distance by the measured map distance, and find your scale. Last, you need to place that ratio onto your map.

Answer:

The answer is "(6,3)".

Step-by-step explanation:

In this question, the point is missing if the given point is (-6,-3) so, its solution can be defined as follows:

Throughout this question whenever we reverse the axis to the mirror at the point. The reflection of (-6,-3) is (6,3), which also is the correct value because it changes the coordinates, that's why (6,3) is the correct point.

Answer:

y = 20 + .5x

Step-by-step explanation:

Suppose that a cell phone monthly rate plan costs the user 5 cents per minute beyond a fixed monthly fee of $20. This implies that the relationship between monthly cost and monthly number of minutes is linear. Write an equation that relates total monthly cost to monthly minutes used.

Fixed monthly fee = $20

Fee per minute = $0.5

Number of minutes = x

Variable monthly cost = 0.5x

Let Total monthly cost = y

Total monthly cost = fixed monthly cost + variable monthly cost

y = 20 + .5x

Equation that relates total monthly cost to monthly minutes used is y = 20 + .5x

Reese: 15

Emily: 22

Step-by-step explanation:

22 - 7 = 15

15 + 22 = 37

Answer:

f=4x-148

62 degrees fahrenheit

Step-by-step explanation:

Chirps per minute=148

x=148

x=4f-148

100=4f-148

248=4f

62=f

If snowy tree crickets chirp at 100 chirps per minute, the temperature outside is 62 degrees fahrenheit.

Answer:

1. g = 4

2. g = 19

3. g = 39

4. g = 59

Step-by-step explanation:

Answer:

4,19,39,59

Step-by-step explanation:

it’s actually pretty simple.

for the first one you take 1 and plug it into n which looks like:

g=5(1)-1

then find yourself answer:

5(1)= 5

5-1=4

answer is 4

then you plug your four into n:

5(4)-1= 19

answer is 19

then you plug your 8 into n:

5(8)-1=39

answer is 39

then you plug your 12 into n

5(12)-1= 59

answer 59

No, you don't have to pay for anything to get expert-verified answers on your questions.

I'm not completely sure, but it could raise the chances of getting your answers to be that, or to have other people with those types answer your questions.

But no, you don't have to pay for anything. I didn't have to pay for anything and I got my answers to be expert verified in the past.

#teamtrees #PAW (Plant And Water)

Step-by-step explanation:

The dot is called a decimal point. It is also called the decimal separator. It separates whole numbers from fractional numbers.

In this example;

24.671

The numbers before the point, 24 is the whole number

The numbers after the point, 671 are the fractional portion of the number. They represent 6 tenths, 7 hundredths and 1 thousandths.

Also, the number of digits after the point tells you how many decimal place the number is in. In this example the number of decimal places is 3.

Answer:

180ft^2

Step-by-step explanation:

lw + lw + lw + bh

[ (11*2.5) + (6.5*11) + (6*11) <- Area of the rectangles ]

[ (6*2.5) <- Area of the Triangles ]

[ (11*2.5) + (6.5*11) + (6*11) ] = 165

[ 6*2.5 ] = 15

165 + 15 = 180

Answer:

Area: 27.5        trees?

Perimeter: 15    trees?

Step-by-step explanation:

Area of a right triangle is its base multiplied by its height

Since the two right triangles are mirror images of each other we only need to focus on one of them and then multiply our answers by 2

since the base of the whole triangle is halved we will do so to its value as well:

[tex]base=\frac{11}{2}[/tex]

we are given the height with the center line:

[tex]height=5[/tex]

so to get the area of one of the right triangles we do:

[tex]\frac{\frac{11}{2}*5}{2}[/tex]

and since there are two of them we can take away that divide by 2 to get:

[tex]\frac{11}{2}*5[/tex] which can be written as [tex]\frac{55}{2} ,\ 27\frac{1}{2} ,\ or\ 27.5[/tex]

now for the perimeter we just add up the outer most sides:

[tex]2+2+11=15[/tex]

(btw these measurements wouldn't make a triangle but that is what is shown so I just went with it)

Answer: A is multiplied by  2  B is multiplied by B and C is multiplied by 2

Step-by-step explanation:

Answer:

[tex]\sqrt{41}[/tex] units

Step-by-step explanation:

To find the distance between two points, we can use the Pythagorean theorem by creating a right-angled triangle where sides a and b are the distances between the y-coordinates and x-coordinates of each point.

First let's find the distance between the x-coordinates:

(9,8): x-coordinate is 9, and (5,3): x-coordinate is 5.

9 - 5 = 4

The first side of our triangle is 4 units.

y-coordinates:

8 - 3 = 5

The second side of our triangle is 5 units.

[tex]a^{2} +b^{2} =c^{2}[/tex]

[tex]4^{2} +5^{2} =c^{2} \\16 +25 =c^{2} \\41 = c^{2} \\\sqrt{41} =\sqrt{c^{2} } \\\sqrt{41} = c[/tex]

Squareroot 41 is fully simplified as 41 is a prime number.

I have attached a picture to help visualize the triangle.
