kiruha [24]

Answer:

The annual interest rate is 6.25%

Step-by-step explanation:

We have been given that

P = $50,000

I = $9,375

t = 3 years

r = ?

The formula for simple interest is given by

$I=Prt\\\\\text{Substituting the known values, we get}\\\\9375=50000(r)\cdot3\\\\r=\frac{9375}{50000\cdot3}\\\\r=0.0625\\\\r=6.25\%$

Therefore, the annual interest rate is 6.25%

BCD= 120 degrees. explanation: the 4 angles of a parallelogram must equal 360 degrees. so you add all 4 angles & get 6x. you then take that 6 & divide it from 360 (360/6) and get 60. therefore x=60. so then you just multiple BCD (2x) by 60 and you get 120 degrees
