Answer:

2,4,5

Step-by-step explanation:

The straight line has representation:

y=kx+n, where k and n are real numbers. We dont have ^2 or any other operation.

So:

1. Is not line because yx=9x-1

2. X=16+3y we can write like y=1/3X-16/3 so it is straight line TRUE

3. Ve have ^2 it is not staight line

4.8x-5y=30 is y=8/5x-6 it is line TRUE

5.y=-6(x+10)=-6x-60 it is line TRUE

6. Y=x(3-x)+1=3x-x^2+1 so we have ^2 it is not straight line.

C is the correct answer

we should find the area of the square and then divide it by 24.
(360/15=24)

$6 \times 6 \times \pi \times \frac{1}{24} = 36 \times \pi \times \frac{1}{24} \\ = 113.04 \times \frac{1}{24} = 4.71$

The volume of a fish tank is 60 cubic feet. If the density is 0.3 fish over feet cubed, how many fish are in the tank? 200 9 100

FinnZ [79.3K]

Answer:

There are 18 fish in the fish tank.

Step-by-step explanation:

The volume of a fish tank is 60 cubic feet: V = 60 ft³.

The density is 0.3 fish over feet cubed. d = 0.3 fish/ft³

We can find the number of fish using proportions. The required conversion factor is 0.3 fish/ft³. The number of fish is:

60 ft³ × (0.3 fish/ft³) = 18 fish

There are 18 fish in the fish tank.
