The interior angles of a quadrilateral shape add up to 360 so 116+93+45+x = 360 with x equaling 106
9514 1404 393
Answer:
$67,200
Step-by-step explanation:
The amount if interest is given by the formula ...
I = Prt
where P is the amount invested, r is the annual rate, and t is the number of years. Here, we want to find P when r = 0.05 and t = 1/2 such that I = 1680.
P = I/(rt) = $1680/(0.05·0.5) = $1680/0.025
P = $67,200
The amount invested was $67,200.
3/4
9/10 times 5/6= 45/60 divide by 3 then divide by 5. 15/20 = 3/4
