Ratios and proportions tie into each other. A ratio in real life would be basically comparing two quantities, as a proportion would be solving for the similar ratio or the equal ratio to another.
It is 3. That's the correct answer
Answer:
<em>The elephants' moat should be 3.2 meters deep.</em>
Step-by-step explanation:
Suppose, the depth of the elephants' moat is 
meter.
Width of the lions' moat is 5 meter and width of the elephants' moat is 4 meter.
Given that, the lion’s moat is 4 meter deep.
So, <u>according to the ratio of width and depth</u>, the equation will be.......
Thus, the elephants' moat should be 3.2 meters deep.
Answer:
About 31 years
Step-by-step explanation:
Given data
Principal= $3500
Rate= 4.75%
Final amount= $15,000
Time=??
The expression for time on compound interest is
Calculate time, solve for t
t = ln(A/P) / r
substitute
Calculate time, solve for t
t = ln(15000/3500) / 0.0475
t= ln(4.2857)/ 0.0475
t= 1.4552/0.0475
t= 30.63 years
Hence it will take about 31 years
