SOMEONE PLEASE HELP!! I've tried this question twice and I just can't seem to get it There are 30 fish in a pond. 9 of the fish are carp. Of the fish that are not carp, 1/3 are sticklebacks and the rest are tench. What is the ratio of carp to sticklebacks to tench in the pond? Give your answer in it's simplest form.

Number of fish that are not carp = Total fish - number of carp fish

Since 1/3 of remaining fish which are not carp are sticklebacks , Number of sticklebacks =

Now ,

Number of tench = Total number of fish - (Number of carp + Number of sticklebacks)

Ratio of carp to sticklebacks to tench in the pond =

SI=(P*R*T)/100

P=2000

R=1.5

T=6

SI=(2000*1.5*6)/100

=(2000*9)/100

=180

Neil will earn interest of 180

Cost of 7 gallons=$24.50

Cost of 1 gallon=24.50/7=3.5

Cost of 15 gallons=15*3.5=52.5

Cost of 15 gallons will be $52.5

The solution is in the following image

y=2x+15

where y=Value of coin

x=Age in years

Value of coin after 19 years=2*19+15

=$53

Therefore, Value after 19 years=$53

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

Approximately it is aqual to 1300kg

The answer is in the image 

The solution is given in the image below

Here,

tip=18%of $32

tip=(18/100)*32

=0.18*32

=$5.76

Total payment=32+5.76=$37.76

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.
