Answer:
b) √200 = 10√2
Step-by-step explanation:
Here, the given expression is: √200
Simplifying the given expression, we get:
200 = 2 x 2 x 2 x 5 x 5
⇒ 200 = (2)² x (5) ² x 2
Taking ROOT both sides, we get:
Hence, √200 = 10√2
Answer:
14
Step-by-step explanation:
I first multiplied 490 by 3/7
giving me 1470/7
I divide 1470 by 7 giving me 210
As I got 210
I multiplied 210 with 2 and got 410/3
I divided 410 by 3, getting 140.
It then said half of what was delivered was put into 5 pound bags, so
140× 1/2 or 140÷2 is 70
70 divided by 5 is 14
They made 14 5-pound bags.

Thus, The time taken by Andrew(in minutes) = time taken by kiran + 5/8 of time taken by kiran
= 
= 
= 
= 
Thus, required equation,
