Answer:

18

Step-by-step explanation:

All I did was count the lines on the coordinate grid between -12 and 6. I was counting by 2's because the grid itself is counting by 2's

Answer:  18

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

Explanation:

If you start at 6, and count the number of spaces to get to -12, you should count out 18 spaces.

Or you could start at -12 and move to 6 to move 18 spaces to the right. Keep in mind each tickmark represents 2 spaces.

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

You could also think of it like this:

Place point A at -12, B at 0, C at 6

The distance from A to B is 12 units. The distance from B to C is 6 units. In total we have AB+BC = 12+6 = 18 units from A to C.

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

Or you could use absolute value and subtraction

Let P = -12 and Q = 6

We could say

|P - Q| = |-12-6| = |-18| = 18

or

|Q - P| = |6 - (-12)| = |6 + 12| = |18| = 18

The order of subtraction doesn't matter as long as you apply absolute value. Absolute value represents distance from 0 on a number line, so absolute value is never negative.

Answer:

422[tex]cm^2[/tex]

Step-by-step explanation:

1. Approach

This problem asks one to find the surface area of the given figure. This can be done by splitting the given figure into two similar figures. Then calculate the surface area of each of the similar figures. After doing so, subtract the covered surface areas, the contact point between the two simple figures is not a part of the surface area since it is covered by the other part of the figure. Remember to take away twice the area of this contact point, since it is present on both figures.

2.Find the surface area of the first figure

The surface area of a figure is the two-dimensional space around the figure. In essence, if one were to wrap the figure in paper, the surface area is the amount of paper one would need. Find the 2-dimensional area of each side, this can be done by multiplying all combinations of two dimensions together, adding the results, and then multiplying that value by (2).

(5) * (10) = (50)

(5) * (7) = (35)

(7) * (10) = (70)

Now add thee value together,

(50) + (35) + (70)

= (155)

Double the result,

(155) * (2) = (310)

3. Find the surface area of the other figure

Now repeat the process that was used to find the surface area of the other figure for this figure.

(8) * (4) = (32)

(4) * (3) = (12)

(8) * (3) = (24)

Add the results,

(32) + (12) + (24) = (68)

Double the value,

(68) * (2) = (136)

3. Now subtract the repeated side

Now that one has the value of both simple figures, add up the value and then subtract twice the value of the repeated side.

(310) + (136) = (446)

(446) - ((2)*(4)*(3))

= (446) - (24)

= (422)

Find the area of each composite figure. Use 3.14 for π. Round to the nearest tenth if necessary. Whats the correct label?

Answers

Step-by-step explanation:

Square= bh

Square= 2×2=

half-circle = 1/2Pi*r×r

half-circle 2 = 1/2Pi*r×r

We would put 1/2 for the half-circle because its half of a circle. And we square it because where finding area. The middle is square, and the two up top is half a circle. Hope that helps :D

There’s two semi-circles with a radius of 2, so it would be 2 x 1/2 x Pi x radius ^2.

Now we need to find the area of the square, which is a^2. The diameter of a circle is double the radius, so we know the sides of the square will equal 4 inches, so 4 x 4.

4 x 4 + 2 x 1/2 x 3.14 x 2^2 should give you your answer. Hope this helps!!

Use a system of equations to find two numbers with a difference of 2 and a sum of -8. Show your work.

Answers

I am not sure I’m sorry

Answer:

-3 & -5

Step-by-step explanation:

let the two numbers be x and y

x + y = -8. sum of the numbers is -8

x - y = 2. difference(-) of the numbers is 2

now we add the two equations

x + x + y - y= -8 + 2

2x = -6

x = -6/2. = -3

substitute value of x in second equation to get y

-3 - y = 2

-y = 2 + 3

-y = 5

y = -5

Answer:

Yes! This is my area!

Step-by-step explanation:

Minimum= 51

Maximum=64

To find the median put the numbers in order

51,53,55,58,60,60,64

no cross off one by one to get the middle number

you end up with 58

first quartile is the upper half so that would be 53

third quartile is the lower half so that wou;d be 60

Hope this helps!

Answer:

D

Step-by-step explanation:

when you put them in numerical order, you have 51, 53, 55, 56, 58, 60, 60, 60, 64

the minimum is the smallest number in the data set. the maximum is the largest number in the data set.

the median is the measure of center, which indicates the middle number in the data set

the first quartile is the center of the bottom set of the data

the third quartile is the center of the upper set of the data

(the upper and lower sets are indicated by which side of the median they are on)
