A fish tank is three-quarters (3/4) full. two-thirds (2/3) of the water leaks out, leaving 10 gallons of water in the tank. what
Naily [24]

To solve this problem, all we have to do is to thoroughly analyze the situation step by step.

First let us work on the remaining 10 gallons of water in the tank. We are given that 2 / 3 of the water initially in the tank leaked out. Therefore this means that we are left with 1 / 3 the original amount of water which is 10 gallons, hence:

(1 / 3) Vi = 10 gallons

where Vi is the initial volume of water inside the tank, calculating for Vi:

Vi = 3 (10 gallons)

Vi = 30 gallons

 

We are also given that this initial volume of water is just 3 / 4 of the total capacity of the tank, therefore:

(3 / 4) Vc = Vi

where Vc is the volume capacity of the tank, calculating for Vc:

Vc = 4 Vi / 3

Vc = 4 (30 gallons) / 3

Vc = 40 gallons

 

Answer:

<span>Capacity of the fish tank is 40 gallons</span>

the table shows the distance randy drove on one day of her vacation. Find the distance randy would have gone if she had driven f
Mandarinka [93]
I found the table that accompanies this problem:

Time(h)                1       2        3      4       5
Distance (mi)    55   110   165  220  275

speed = distance / time
speed = 55/1 = 55 miles per hour

speed = 110/2 = 55 miles per hour
speed = 165/3 = 55 miles per hour
speed = 220/4 = 55 miles per hour
speed = 275/5 = 55 miles per hour

distance = speed * time
distance = 55 miles per hour * 6 hours
distance = 330 miles.

To get the distance traveled, simply multiply the speed by the number of hours spent travelling.
