Answer:
B. 
Step-by-step explanation:
The question is not properly presented. See attachment for proper presentation of question
From the attachment, we have that:




Required
Order from greatest to least
First, we need to simplify each of the given expression (in decimals)



Take square root of 3


--- approximated



Take π as 3.14


--- approximated
List out the results, we have:

Order from greatest to least, we have:

Hence, the order of arrangement is:

i.e.

Answer
x=12
Step-by-step explanation:
The second and the third one are similar.
Answer:
We have, 63% × x = 252
or,
63/100 × x = 252
Multiplying both sides by 100 and dividing both sides by 63,
we have

x = 400

Answer: x=7.7, y=40
3/x = 15/38.5
38.5*3=115.5
115.5/15= 7.7
x=7.7
3/8 = 15/y
15*8=120
120/3= 40
y=40
orrrr you can just easily find the scale factor which is 5, multiply 8 by 5 and get 40. And 38.5/5 which is 7.7
