answer: 42
Answer:
10 easy levels and 10 difficult levels
Step-by-step explanation:
Given data
let the number of easy levels be x
and the number of difficult levels be y
so
x+y= 20----------1
and
3x+5y= 80------2
from 1
x=20-y
put this in 2
3(20-y)+5y= 80
60-3y+5y=80
2y=80-60
2y=20
y= 20/2
y= 10
put y= 10 in 1
x+10=20
x=20-10
x= 10
Hence Kiran played 10 easy levels and 10 difficult levels
Answer:
A
Step-by-step explanation:
You should know the area of a circle, A = πr².
So, all you need to find is the area of half a circle, or A = 
πr²
We see that the radius is half of the diameter or r = 6 in.
A = (3.14)(6)²
A = 56.52 in²
