Answer:
A.) in 6 hours Rovan can make 288 tarts 
B. at this rate it'll take Rovan about 2 and a half hours to make 120 tarts
Step-by-step explanation:
so if Rovan can make 48 tarts an 1 hour take 48 and multiply it by the hours to find out how many tarts he can make 
48 x 1 =48
48 x 2 =96
48 x 3 =144 .....
48 x 6 =288

X=width of the lake 
y=length of the lake.
we set out this system of equiations
x*y=9/20 
x=y/5
we solve by sustitution method
(y/5)*y=9/20
y²/5=9/20
y²=(5*9)/ 20
y²=2.25
y=√2.25=1.5
x=y/5
x=1.5/5=0.3
Solution:
width of the lake=0.3 miles
lenght of the lake=1.5 miles

Answer:
200 people 
Step-by-step explanation:
Let: the number of people who surveyed be: x
Therefore, (160/x) x 100=80%
=> x=(160x100)/80
=>x=16000/80
=>x= 200
Thus, 200 people surveyed.
