Answer:
A. Angel fish = 48
B. Gold fish = 36
Step-by-step explanation:
Clown fish : angel fish = 5 : 4
Angel fish : gold fish = 4 : 3
Clown fish = 60
A. How many angel fish are there
Let x = number of angel fish there
Clown fish : angel fish = 5 : 4
Clown fish : angel fish = 60 : x
Equate the ratios
5 : 4 = 60 : x
5/4 = 60/x
Cross product
5 * x = 4 * 60
5x = 240
x = 240/5
= 48
x = 48
Angel fish = 48
B. How many gold fish are there
Let
y = number of gold fish there
Angel fish : gold fish = 48 : y
Angel fish : gold fish = 4 : 3
Equate both ratios
48 : y = 4 : 3
48/y = 4/3
Cross product
48 * 3 = y * 4
144 = 4y
y = 144/4
= 36
y = 36
Gold fish = 36

Answer: i believe the answer is 26
Step by step explanation
Total no. of observation = (12+13) = 25
Median = Average of 18/2 observation + (18/2+1)
=1/2 (12th observation + 13 observation)
1/2 × (25 +27) = 1/2 × 52
=26
Answer:
B
Step-by-step explanation:
You just need to find the volumes of both container and soap and divide them. So;
Volume of Soap = 15cm * 8cm * 6cm = 720 cm^3
Volume of Container = 165cm * 40cm * 96cm = 633600 cm^3
Dividing them gives = 633600 cm^3 / 720 cm^3 = 880
Answer is B.
