There are 1,000 fish in a lake. Each year the population declines by 15%, but afterward, the lake is restocked with 500 aditional fish. Write a recursive rule to find the number of fish in the lake for any year

Answers

We begin with 1,000 fish in a lake.
Each year the population declines to 15%
Then they put back 500 fish in the lake.

The equation: (1000 * .85) +500

A barge travels twice as fast when it is empty as when it is full. If it travels 20 miles northwith a cargo, spends 20 minutes unloading, and returns to its original port
empty, taking 8 hours to complete the entire trip, what is the speed of the barge when it
is empty?

Answers

V1=(empty)=2*v2(full)
20+20 (go+return)
t1+t2=8hour-20’(1/3 hour)=23/3hour
t1=23/3-t2
v1*t1+v2*t2=20+20
2v2*(23/3-t2)+v2*t2=40
2v2*23/3-2v2*t2+v2t2=40
2v2*23/3-v2t2=40
2v2*23/3-20=40
2v2*23/3=60
v2=60/46/3=180/46=90/23
v1=2*90/23=180/23

7÷3×5x÷12. Can someone help me multiply rational expressions and divide rational expressions? Please and thank you.

Answers

In this case, because there are no exponents or brackets, (BEDMAS) you would just do it in the order given.

7÷3×5x÷12= 7×1/3 × 5x × 1/12
To divide, make the numbers after the divide sign into fractions.(ex: 3= 1/3)
Then multiply it out:
= 7/3 × 5x/12
= 35x/34
Then because the numerator is bigger then the denominator, make the improper
fraction into a mixed fraction:
= 1 1x/34

Hope this helps!

Which number are greater than
0.6 0.39 0.07 0.8 0.69 0.17

Answers

Let's turn them in to fractions.

$0.6\quad 0.39\quad 0.07\quad 0.8\quad 0.69\quad 0.17\n \n 0.6=\quad \frac { 6 }{ 10 } =\frac { 60 }{ 100 } \n \n 0.39=\frac { 39 }{ 100 } \n \n 0.07=\frac { 7 }{ 100 } \n \n 0.8=\frac { 8 }{ 10 } =\frac { 80 }{ 100 } \n \n 0.69=\frac { 69 }{ 100 } \n \n 0.17=\frac { 17 }{ 100 }$

$\frac { 60 }{ 100 } \quad ,\quad \frac { 39 }{ 100 } \quad ,\quad \frac { 7 }{ 100 } \quad ,\quad \frac { 80 }{ 100 } \quad ,\quad \frac { 69 }{ 100 } \quad ,\quad \frac { 17 }{ 100 } \n \n \frac { 80 }{ 100 } >\frac { 69 }{ 100 } >\frac { 60 }{ 100 } >\frac { 39 }{ 100 } >\frac { 17 }{ 100 } >\frac { 7 }{ 100 }$

Turn back into decimals again.

$0.8>0.69>0.6>0.39>0.17>0.07$

I believe its this because you didnt make enough space...
