Step-by-step explanation:
Pythagorean Theorem is a^2 + b^2 =c^2
a= 9 , b= 15, c= x
9^2 + 15^2 = c^2
= c^2
c= 17.493 or 17.5 rounded to the nearest tenth
To earn $345.45 simple interest in 7 years, you have to invest $940.
<u>Step-by-step explanation:</u>
Step 1:
Given details are Simple Interest Rate (R) = 5.25%, Simple Interest (SI) = $345.45, Time (T) = 7 years
Step 2:
Use the above details to find principal using the formula for Simple Interest (SI) = PRT/100
⇒ 345.45 = (P × 5.25 × 7)/100
⇒ 34545 = 36.75 P
⇒ P = $940
