Answer 5

The volume of a fish tank is 40 cubic feet. If the density is 0.4 fish/feet^3, how many fish are in the tank? (1 point)
Select one:
a. 16
b. 4
c. 100
d. 10

Answer 6

there has to be a formula for this one to

Answer 7

@HB0102

Answer 8

density = number / volume

Answer 9

0.4= x/40

Answer 10

so what am i supposed to do

Answer 11

find x
multiply 40 on both sides

Answer 12

0.4= x/40
how are we supposed to multiply 40 on the right side

Answer 13

left side
0.4*40

right side
x*40/40 = x

Answer 14

what does x equal

Answer 15

0.4*40

Answer 16

x is the number of fish in the tank

Answer 17

but you said right side x*40/40 = x

Answer 18

thts correct.
so?

Answer 19

but i thought left side 0.4*40

Answer 20

it is.

Answer 21

why and where are you confused ?

Answer 22

calculate whats 0.4*40
thats would be your answer

Answer 23

The density of a fish tank is 0.4 fish/feet^3 There are 12 fish in the tank. What is the volume of the tank? (1 point)
Select one:
a. 3 ft3
b. 30 ft3
c. 48 ft3
d. 96 ft3

Answer 24

@hartnn

Answer 25

same formula

Answer 26

density = number / volume
0.4 = 12/ v

Answer 27

i know i did 12 times 0.4 and 4.8 came out

Answer 28

no..
0.4 = 12/v

so v = 12/0.4 = 120/4

Answer 29

so do 12/4 then

Answer 30

i mean 120/4

Answer 31

i got 30 is that correct

Answer 32

yes

Answer 33

thank you
