Answer:

28 fish

Step-by-step explanation:

The density here is written as fish over feet cubed, so this equation can be written as 0.4=x fish/70 cubic feet

To get x alone you must multiply 0.4 by 70 to get 28, which represents the number of fish

This questionn please

nasty-shy [4]

Let X be the total number of guests
$\frac{1}{3} x + \frac{5x}{12} + 23 \\ \frac{12x + 15x + 828}{36} \\ \frac{17x + 828}{36}$
when X =1
(17+828)/36
845/36=23.5
am sorry but the question is not that clear

Find the probability of rolling two number cubes and getting a 2 on the first number cube and a 6 on the second?

Tanzania [10]

Answer:

Step-by-step explanation:

A cube has 6 sides

Only one side of the cube has 2 on it

The probability of getting 2 would be 1/6

Only one side of the cube has 6 on it

The probability of getting 6 would be 1/6

For both events to happen together

1/6 x 1/6 = 1/36

Answer:

You need to find the surface of each area and sum them up.

Step-by-step explanation:

You will need the surface area for each side.

So 2 up-bottom, 2 left-right and two front-back

2*(4*3) + 2*(2*4) + 2(3*2)

2*12 + 2*8 + 2*6

24 + 16 + 12

Total area = 52
