<span>the answer:
the interpreted function is S(t) =9t-4, t = time in days, and S = number of people in thousands. The question consists of finding the value of S(4) and its meaning; for that, we replace the value of t by 4, in the equation S(t) = 9t -4, that is S(4) = 9*4-4=36-4=32, S(4) =32, in every four hours, 32 thousands people is attacked by swine flu. To find the value of t, when S(t)= 23, we have 9t-4 = 23, and then 9t= 23+4=27, t =27 / 9 = 3 so t = 3. S(t) = 23 does mean the value of time when 23 thousands of people is attacked by flu.</span>
Answer:
Janet should receive $1.20
Kay should receive $0.80
Step-by-step explanation:
Janet=2 gallons
Kay=1 3/4 gallons=1.75
Total=2+ 1 3/4
=2+7/4
=8+7/4
=15/4 gallons
They agreed to share it equally
15/4÷3
=15/4×1/3
=15/12=1.25
=5/4 each individual gets 5/4
Janet=2-1.25=0.75
Janet gave up 0.75 gallonsof her water
The percentage is
0.75/1.25×100
=0.6×100
=60%
Kay=1.75-1.25=0.50
Kay gave up 0.50 gallons of her water
The percentage is
0.50/1.25×100
=0.4×100
=40%
Janet gets 60% of $2
60/100×$2
=0.6×$2
=$1.2
Kay gets 40% of $2
=40/100×$2
=0.4×$2
=$0.8
