Sally invests $10,500 in an account that earns 6% annual simple interest. Assuming she makes no additional deposits or withdrawals, how much interest will Sally earn after 4 years?
I SWEAR I WILL MARK YOU BRAINIEST

$2520

Step-by-step explanation:

The simple Interest earned on a deposit of P that has a rate of r% and a period of t years can be calculated by using the formula:

(P × R × T)/100

where P is principal

R is rate

T is time

P=$10,500

R=6%

T=4 years

Therefore:

Interest= (10500 × 6 × 4)/100

= 252000/100

= 2520

Sally will earn $2520 as interest after 4 years.

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
