Alocal boys club sold 176 bags of mulch and made a total of 520. it sold two types of mulch hardwood for 3.50 a bag and pine bark for 2.75 a bag. how many bags of each kind of mulch did it sell

Not enough information it could be any amount of each by multiples

  n=   0.0000 - 0.3750 i  

  n=   0.0000 + 0.3750 i

step-by-step explanation:

one of these should be correct

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
