mZLON is a straight angle.
MZLOM = 4x + 30°
mZMON = 8x + 90°
Find mZMON:
Help pls
Step-by-step explanation:
these are supplementary angles
LOM + MON = 180
(4x + 30) + 8x + 90 = 180
12x + 120 = 180
solve for x and then substitute into 8x +90

Two pyramids are similar. Their base edges are a ratio of 3:5. Find the ratio of their surface area.
Answer:
9/25
Step-by-step explanation:
Two pyramids are similar. Their base edges are a ratio of 3:5. Find the ratio of their surface area.
The ratio of the surface area is calculated as the square of the ratio of the edges
Hence,
Ration of surface area = 3²/5²
= 9/25

hi guys, can you please answer this question i'm giving out brainliest and 30 points:)
Answer:
1 centimet
Step-by-step explanation:
Answer:
A Centimeter!
Step-by-step explanation:
Heard of the Acronym
King Henry Died m Drinking Chocolate Milk
K = King = Kilometers
H = Henry = Hectometers
D = Died = Decameters
M = m = meters
D = Drinking = Decimeters
C = Chocolate = centimeters
The metric system is based on the power of ten.
There are 10 Decimeters in a meter
There are 100 Centimeters (your answer) in a meter
There are 1000 Millimeters in a meter
Similarly:
1 Decameter = 10 meters
1 Hectometer = 100 meters
1 Kilometer = 1000 meters
So you can use it for this:
1 Hectometer = (10x10x10x10)cm or 10,000 cm
In this problem I am starting at 10, and multiplying as many tens as I need to get to Hectometer ( refer acronym).
Centimeters to Decimeters = 10
Decimeters to Meters = 10
Meters to Decameters = 10
Decameters to Hectometers is 10
So we have 4 - 10s so we do 10x10x10x10 or 10,000 cm in a Hectometer
1 cm would equal 0.0001 Hectometer
or 1/10,000 of a cm

The table shows the heights of 10 randomly selected second-grade students.
Helght (Inches)
44 45 47 49 48 48 49 50 48 52
Based on the data, select the most reasonable prediction about the height of second-grade students.
O A. The typical second-grade student is less than 45 inches tall.
B. The typical second-grade student is about 45 inches tall.
C. The typical second-grade student is more than 50 inches tall.
D. The typical second-grade student is about 48 inches tall.
Answer:
Answer = D
Step-by-step explanation:
If you add all of the heights up you get 480. divide that by ten (because there were 10 students whose height was taken) then you get 48. therefore, the typical second-grade student is about 48 inches tall.
I hope this helps have a good day :)
The typical second-grade student is about 48 inches tall.
What is mean?'Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers.'
According to the given problem,
Given data = { 44, 45, 47, 49, 48, 48, 49, 50, 48, 52 }
Sum of the given data = 44 + 45 + 47 + 49 + 48 + 48 + 49 + 50 + 48 + 52
= 480
Average of the given heights = [tex]\frac{480}{10}[/tex]
= 48
Hence, we can conclude, The typical second-grade student is about 48 inches tall since the average of the given data is 48.

Determine whether there is a good line of best fit for the given graph. Then, if there is a good line of best fit, determine if the correlation is
positive or negative.
Answer:
The line's slope equals the difference between points' y-coordinates divided by the difference between their x-coordinates. Select any two points on the line of best fit. These points may or may not be actual scatter points on the graph. Subtract the first point's y-coordinate from the second point's y-coordinate.

solve for h
Answer:
Step-by-step explanation:
assuming that the triangles are similar, which I can't by what is shown in the picture, but I'm guessing that there are more instructions off screen , that say they are.
' = feet
" = inches
h / 20' = 4'-2" / 3'-4"
just use inches for this, it's easier
h / 240" = 50" / 40"
h = 240 ( 50 / 40 )
h = 300"
h = 25'

Point A and point B are places on a number line. Point A is located at -20 and point B is 5 less than point A.
Which statement about point B is true?
Answer:
B = -25
Step-by-step explanation:
Note :-
Firstly there's no options mentioned in the question . So I would be providing you with the location of point B !
Given :-
A abd B are on no . line .A is located at -20 B is a point 5 less than point A.By question , the Point A is at -20. And B is 5 less than A. So the location of point B on the number line is ,
→ B = -20 - 5
→ B = -25
Hence the location of point B on the number line is -25.Please and thank you someone help me out
