Juli2301 [7.4K]

Answer:

The total height of coconut Tree = H + 10ft = 11.77 ft

Step-by-step explanation:

Given as,

The height of Kalei = 6ft

The distance of Kalei from the coconut Tree = 10 feet

Angle of elevation of kalei up to the coconut on tree = 30°

<u>Note : look at the pic attache </u>

From figure it is mention that

Total height of Tree = 6 ft + H

So, Tan 30° = \frac{perpendicular}{base}

     Tan 30° = \frac{H}{10}

    ∴ H         = 10 Tan 30° = 10 × 0.577         Note : tan 30° = 0.577

i.e    H         = 5.77 ft

Hence the total height of coconut tree = 6 + 5.77 = 11.77 ft   Answer

A company borrowed $25,000 at 3.5% and was charged $2,625 in interest. How long was it before the company repaid the money?
nirvana33 [79]
Hello

3 years. Since no mention of compounding was made I will assume that it's 3.5% simple interest. So first, let's calculate what percent of the entire loan was interest. Just a simply matter of division. 2625 / 25000 = 0.105 = 10.5% Now lets' divide the percentage of the loan that was paid in interest by the interest rate. 10.5% / 3.5% = 3 So the company took 3 years to repay the loan.
Have a nice day
