Is it a multiple choice question? I mean, 10/80?..
Answer:
40 patients
Step-by-step explanation:
Divide 25 by 5 to get 5 patients per hour (the rate).
Since there are 8 hours, multiply 8 by 5 to get 40 patients in 8 hours.
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
