Answer:
Step-by-step explanation:
Given △KMN, ABCD is a square where KN=a, MP⊥KN, MP=h.
we have to find the length of AB.
Let the side of square i.e AB is x units.
As ADCB is a square ⇒ ∠CDN=90°⇒∠CDP=90°
⇒ CP||MP||AB
In ΔMNP and ΔCND
∠NCD=∠NMP (∵ corresponding angles)
∠NDC=∠NPM (∵ corresponding angles)
By AA similarity rule, ΔMNP~ΔCND
Also, ΔKAP~ΔKPM by similarity rule as above.
Hence, corresponding sides are in proportion
Adding above two, we get

Hi!
All of these can be represented as fractions:
1.) 4/12
2.) 15/27
3.) 12/18
4.) 9/72
Now, if they are supposed to be <em>simplified</em>...
1.) Divide 4 and 12 by 4, and you get 1/3
2.) Divide 15 and 27 by 3, and you get 5/9
3.) Divide 12 and 18 by 6, and you get 2/3
4.) Divide 9 and 72 by 9, and you get 1/8
Hope this helps! :D
ANSWER: you have to figure out if it’s proportional
Step-by-step explanation:
You can do this by:
Seeing if it increases, has a slope, if it has a curve or straight line (straight line, proportional)
Answer:
1.25
Step-by-step explanation:
Give the data:
X : 1 1/2 ___ 0 _____ 4 ______ 2 1/2
Mean absolute deviation (MAD) :
Σ|x - xbar| ÷ n
xbar = Σx/ n
Σx = (1 1/2 + 0 + 4 + 2 1/2) = 8
xbar = 8/4 = 2
|x - xbar| :
|1 1/2 - 2|= 1/2
|0 - 2| = 2
|4 - 2| = 2
|2 1/2 - 2| = 1/2
Therefore,
MAD = (1/2 + 2 + 2 + 1/2) / n
MAD = 5/4
MAD = 1.25
