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
Place value. when multiplying by 10 you are moving a decimal, having everything lined up like place value would save you a lot of time.
I believe it's a segment.
Tangent (25) = opp / adj = 42 / horizontal distance
horizontal distance = 42 / tangent (25)
horizontal distance = 42 / 0.46631
horizontal distance =
<span>
<span>
<span>
90.068838326435200
</span>
</span>
</span>
horizontal distance =
90.1 feet
bearing in mind that 9 months is not even a year, but since there are 12 months in a year, then 9 months is really 9/12 years.
