Answer:
The mom ate 49 fish.
Step-by-step explanation:
This question can be solved by a rule of three.
a mother otter is fed 7 fish for every 2 fish for its cub
if a cub has eaten 14 fish , how many fish did the mother eat ?
For each 2 fish cub eats, the mon eats 7. How much has the mom eaten if the cub has eaten 14?
So
2 - 7
14 - x
2x = 14*7
Simplifying by 2
x = 7*7
x = 49
The mom ate 49 fish.
<h3>
Answer:</h3>
4.5% annually
<h3>
Step-by-step explanation:</h3>
Simple interest is the amount of interest added to a singular sum of money at a fixed rate.
Formula
The formula for simple interest is A = P(1+rt). In this formula, A is the total amount of money in the account, P is the original amount deposited, r is the rate of interest as a decimal, and t is the time in years.
Calculations
To find the rate, plug the information we know into the formula above
Divide both sides by 100
Subtract 1 from both sides
Divide both sides by 5
This gives us the rate as a decimal. So, to find the rate as a percent. Do this by moving the decimal 2 places to the right (or just multiply by 100, they do the same thing). This means that the rate of simple interest is 4.5%.
