Answer:
3 : 5
Step-by-step explanation:
Given 2 similar figures with linear scale factor = a : b , then
ratio of areas = a² : b²
Here ratio of areas = 9 : 25 , thus
linear ratio = : = 3 : 5
Using the equation y=9x you can substitute x for the hours. Y=9 times 5 and y=9 times 8. Y=45 and y=72. The range is $45-$72
Answer:
n=7.87 years
Step-by-step explanation:
- The principal amount of $8000 doubles to become $16000.
-Given the rate is 9% compounded semi-annually, we first determine the effective rate:
We use this rate to in the compound interest formula to solve for n:
Hence, it takes 7.87 years for the amount to double to $16,000
The average change of altitude per minute would simply be
the ratio of distance descended over time. That is:
average change of altitude = distance / time
average change of altitude = 0.44 mile / 0.8 minutes
<span>average change of altitude = 0.55 mile / minute</span>
The answer is SSS . This is because the sides values are shown.
