Answer:

p-r/6=-6-(-6)/6=-6+1=-5

2:

p-(m-n)= -1-(-4-4)=-1-(-8)=-1+8=7

(z+y)/2)3=(-5-4)/3=-9/3=-3

4:

m/6-n=6/6-6=1-6=-5

k³-h=3³-(-2)=27+2=29

p-(p-(m-3))=5-(5-(4-3))=5-(5-1)=5-4=1

(k)(k-j)+3=(5)(5-5)+3=5*0+3=3

p²/6-q=6²/6-4=6-4=2

A group of naturalists catch, tag and release 121 trout into a lake. The next day they catch and release 48 trout, of which 22 h

RideAnS [48]

Answer:

264.

Step-by-step explanation:

Let x represent the number of trout in the lake.

We have been given that a group of naturalists catch, tag and release 121 trout into a lake. The next day they catch and release 48 trout, of which 22 had been tagged.

Using proportions, we will get:

$\frac{\text{Total trouts}}{\text{Tagged trouts}}=\frac{48}{22}$

$\frac{x}{121}=\frac{48}{22}$

$\frac{x}{121}*121=\frac{48}{22}*121$

$x=\frac{24}{11}*121$

$x=24*11$

$x=264$

Therefore, there would be approximately 264 trout in the lake.
