If 30% of John's photographs were perfect, but 210 photographs were not perfect, then how many photographs were there in all?

anyanavicka [17]

If 30% were perfect, 70% were not perfect. So we know that 70% of the total number of photographs is 210.

p(70/100)=210 multiply both sides by 100

70p=21000 divide both sides by 70

p=300

So there are 300 photographs in all.

Hi, can you help me to find (if passible) the complement andsupplement of the angle 3pi/ 4.

nika2105 [10]

Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees.

In radians this are

$\begin{gathered} \frac{\pi}{2}\text{ for }90\degree \\ \pi\text{ for }180\degree \end{gathered}$

To find the complement of 3π/4, subtract it by π/2

$\frac{\pi}{2}-\frac{3\pi}{4}=-\frac{\pi}{4}$

To find the supplement of 3π/4, subtract it by π.
