In 16 years if her parents put in $1,000 and accrues 3.75% interest annually; in 16 years she will have $1,600 in the account.
To find this we need to multiply the amount deposited originally, by the annual percentage, by the amount of years in total.
We'll change the percentage into a decimal by moving the decimal two places to the right; which will change it to 0.0375.
Our equation will look like this:
1,000 x 0.0375 x 16
1,000 x 0.0375 = 37.50
37.50 x 16 = 600.
So, in 16 years at 3.75%, she will earn $600 in interest.
We'll add the interested of $600 to the original deposited amount of $1,000.
$1,000 + $600 = $1,600.
Answer:
; 
Step-by-step explanation:
You can write two expressions that are in terms of 'x' and 'y'. This is a right triangle, so Pythagorean's theorem can be used. We can also use the angle to find the sine of 30 degrees.
<u>Pythagorean's Theorem:</u>
The values 'a' and 'b' are the two shorter sides of the triangle, while the value 'c' is the longest side of the triangle; the hypotenuse.



<u>Sine of the Angle:</u>
Sine is defined to be the opposite side divided by the hypotenuse. Let's take the sine of 30 degrees:




Plug this value of 'y' into the first expression derived from Pythagorean's theorem:






Use this value of 'x' to solve for 'y' in the expression from Pythagorean's theorem:
