Answer:
well it uses the compound interest formula
F(x) = P_{0}(1 + \frac{r}{100})^x
so in your question
x = time in years for the initial formula
P_{0} = 293,.... r = 6% ...and...
then you need to substitute x = 4
simplify the brackets and you should get the answer.
44 inches.
All you have to do is find out what 10% of 40 is then add it back to 40. In the case of finding 10% of something you just “chop” of the back number (or move the decimal place forward) so 10% of 40 is 4. The. 40+4=44.
You can also multiply fractions to find the percent of a number but that is not necessary in this case.
Answer: 0.83
Step-by-step explanation:
The fraction of Teddy's cousins what can do push-ups is 
. We get this fraction because the problem states that 5 of Teddy's 6 cousins can do 15 push-ups. Now that we have our fraction, we divide to get our decimal.
The formula for the light bend would be n1*sin i= n2 * sin r
If you use "sin (90-x)= cos x" principle, you can change the sin in the equation into
n1*sin i= n2 * sin r
n1 * cos a= n2 * cos b
n2/n1= cos a/ cos b
Assuming the n constant is the ratio of the glass compared to water then the answer would be: cos a/ cos b
