A leaking pond looses 18 gallons of water in 34 hours , how many gallons will be left after 41 hours
Ann [662]

The amount of water left = 21.3 gallons.

We have a leaking pond which looses 18 gallons of water in 34 hour.

We have to determine how many gallons of water will be left after 41 hours.

<h3>What do you understand by gallon?</h3>

The gallon is a unit of volume in imperial units and United States customary units.

I gallon = 231 cubic inches = 3.785411784 liters.

According to question, we have -

Amount of water lost by the pond in 34 hours = 18 gallons

Therefore -

Amount of water lost by the pond in 1 hour = \frac{18}{34}

So, the amount of water loosed by the pond in 41 hours = \frac{18}{34}\times 41  = 21.3

Hence, the amount of water left = 21.3 gallons.

SIZIF [17.4K]
We'll solve this equation in order to find the score of the 4th test, which we denote with x. \frac{92+87+78+x}{4}=80. Solving it we find that x=63. And it is the final answer for this problem.

A chocolate company produces 2 types of chocolate: type a and type b. The company selects 25 random packages of each type to che
Taya2010 [7]

Answer:

80 chocolates type 'a' and 240 chocolates type 'b'

Step-by-step explanation:

The company selects 25 random packages of each type from which one of type a has an incorrect weight and three of type b have an incorrect weight.

We can say that \frac{1}{25}=0.04 = 4% of the chocolates type 'a' have an incorrect weight while \frac{3}{25}=0.12 = 12% of chocolates type 'b' have an incorrect weight.

Now, if the company selects 2000 random chocolates of each type we ca predict that the amount of chocolates that have an incorrect wright will be:

Type 'a': 2000x0.04 = 80

Type 'b': 2000x0.12 = 240

So the company is expected to find 80 chocolates type 'a' and 240 chocolates type 'b' that have incorrect weight.
