Answer: 4 fishes
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a sphere = 4/3 x π x (diameter/2)^3
Replacing with the values given:
V = 4/3 x π x (18/2)^3
v = 4/3 x π x (9)^3 = 3,053.63 in3
Next, we have to divide the volume of the tank by 693 in3 (volume for each fish)
3,053.63/693 =4.40 = 4 fishes
Feel free to ask for more if needed or if you did not understand something.

A dime is worth 10 cents and a quarter is worth 25 cents.
Let D be the number of dimes and Q be the number of quarters.
Since the total amount of coins in the pocket is 32, then:

On the other hand, the total value of D dimes is 10D, while the total value of Q dimes is 25Q. Then, the total value of D dimes and Q cuarters is 10D+25Q, which must be equal to 545. Then:

Notice that we have found a 2x2 system of equations:

Solve the system using the substitution method. To do so, isolate D from the first equation and replace the expression for D into the second equation to obtain a single equation in terms of Q:

Replace back Q=15 into the expression for D to find the amount of dimes:

Therefore, the amount of dimes that the man has is 17.
