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
========================================================
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.

Find the area of each composite figure. Use 3.14 for π. Round to the nearest tenth if necessary. Whats the correct label?
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
The circumference of a circle is 50.24 meters. What is the circle's radius?
Use 3.14 for
the formula for the circumference of a circle is pi time diameter.
reverse this and do: 50.24/3.14
this is 16.
the diameter of the circle is 16 meters

Part A: Identify the Minimum, First Quartile, Median, Third Quartile, and Maximum for the data.
64, 53, 60
60, 56, 58
51, 55, 60
A. Minimum: 51, First Quartile: 55, Median: 58, Third Quartile: 60; Maximum: 64
B. Minimum: 51, First Quartile: 55.5, Median: 59, Third Quartile: 60; Maximum: 64
C. Minimum: 51, First Quartile 54.5, Median: 57, Third Quartile: 60; Maximum: 64
D. Minimum: 51, First Quartile: 54, Median: 58, Third Quartile: 60; Maximum: 64
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)
hope this helped :)

Answer:
A. 38 degrees
Step-by-step explanation:
That entire angle is supplementary meaning it will add up to 180 degrees. So we are given 52 and 90 because of the right angle. Those together come to 142 then subtract that from 180 and get 38 degrees.

The difference of x and y is 14. The value of x is 3 more than twice the value of y. Write two equations and graph to find the value of x.
Answer:
system of equations
Step-by-step explanation:
x-y=14
x = 2y+3
x - y = 14
x -2y = 3
x - y = 14
-x + 2y = -3
y = 11
x = 25

Don't forget to brainliest me
Answer:
4 crickets
Step-by-step explanation:
On the first day, the lizard ate 50% of the 10 crickets it was given. 50% of 10 is 5 (10 times 0.5), so five crickets remain. The next day, the lizard ate 20% of the 5 remaining crickets. 20% of 5 is 1 (5 times 0.2), and 5-1=4, so 4 crickets are left.

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