Answer:
45
Step-by-step explanation:
20 goes into 100 5 times so then you tka e the 9 and x 5 and you get 45
S is stocks and b is bonds
s + b = 28800
3b = 5s or s = 3/5 b
substitute in for s
3/5 b + b = 28800
3b + 5b = 144000
8b = 144000
b = 18000 amt in bonds
s + 18000 = 28800
s = 10800 amt in stocks
5y=-61
y=-61/5
I think this question is not fully wrote out
The ratio of neon fish to all the fish in the aquarium is 3 : 4 .
In the question ,
it is given that
in Mrs. Jone's class room there are angel fish and neon fish
number of angel fish in the aquarium = 14 fish
number of neon fish in the aquarium is = 42 fish
So, the total number of fish in the aquarium = number of angel fish + number neon fish
total number of fish = 14 + 42
= 56
the ratio of neon fish to all the fish in the aquarium is
= number of neon fish : total number of fish
= 42 : 56
since the ratio is written in simplest form ,
we get
= 6 : 8
= 3 : 4
Therefore , The ratio of neon fish to all the fish in the aquarium is 3 : 4 .
