Answer:

The equations should have been added up to equal 180 instead of being set to equal each other. The two are supplementary angles, which can be seen due the rule that a pair of interior angles on the same side of the transversal is supplementary. To fix this issue from the work that they did, they should subtract the 140 from 180, so the correct measure of DKH is actually 40 degrees.

A man deposits $ 14,850 into a bank, which pays 4% interest that is compounded

Ganezh [65]

Given:

Principal = $14850

Rate of interest = 4% compounded semiannually.

Time = 3 years

To find:

The amount after 3 years.

Solution:

Formula for amount is:

$A=P\left(1+\dfrac{r}{n}\right)^{nt}$

Where, P is principal, r is the rate of interest in decimal, n is the number of times interest compounded and t is the number of years.

The interest is compounded semiannually, so n=2.

Putting $P=14850, r=4, n=2, t=3$ in the above formula, we get

$A=14850\left(1+\dfrac{0.04}{2}\right)^{2(3)}$

$A=14850\left(1+0.02\right)^{6}$

$A=14850\left(1.02\right)^{6}$

On further simplification, we get

$A=14850(1.12616242)$

$A=16723.511937$

$A\approx 16723.51$

Therefore, the amount in the account after three years is $16723.51.
