HELP ME PLZ IM CRYING predict the number of catfish kathy will catch next week if she catches 54 fish

marishachu [46]

Answer:

Step-by-step explanation:

Take a breath :) . I've got your back.

If she caught 6 carp + 8 bass + 7 catfish, she caught 6 +8 +7 fish total = 21.

7 of 21 were catfish.

If she catches 54 fish instead of 21, (and we have to assume the ratio stays the same), how many will be catfish?

Ratios are 7:21 and x:54, but we'll write them as fractions:

7/21 = x/54

Then cross multiply:

21x = (54)(7)

21x = 378

divide both sides by 21

x = 18

If she catches 54 fish total, we predict she will catch 18 catfish.

---------------------------------------------

If we go back to the original 7/21, we can reduce that to 1/3. Then ask what is 1/3 of 54? 18.

A forensic detective is called to the scene of a murder at 2 am. When she checks the temperature of the body, she sees that it i

Newton's Law of cooling is
$T(t)=T_{a}+(T_{0}-T_{a})e^{-0.1947t}$
where
T(t) = temperature of the body after t hours, 80 °F
$T_{a}$ = ambient temperature, 65 °F
$T_{0}$ = normal body temperature, assumed to be 98.6 °F

The elapsed time since death is obtained from
$65+(98.6-65)e^{-0.1947t|} = 80$
$33.6e^{-0.1957t}=15$
$-0.1947t=ln \frac{15}{33.6}$
$t= \frac{ln(15/33.6)}{-0.1947} =4.142$

4.142 hours before 2 am is 9:52 pm (the previous day) approximately.

Answer: 9:52 pm the previous day.
