Suppose that there are 67 butterfly species for every 22,000 insect species and there are 15,000 to 22,000 species of butterflies worldwide. how many insect species are there

There are 4,925,250 to 7,223,700 insect species worldwide.

Step-by-step explanation:

Supposing that there are 67 butterfly species for every 22,000 insect species and there are 15,000 to 22,000 species of butterflies worldwide, in order to know how many insect species are there we have to do the following calculation:

22,000 (insect species) / 67 (butterfly species) = X (relation of butterfly and insect species)

22,000 / 67 = X

328.35 = X

There are 328.35 insect species for every butterfly species.

So, as there are 15,000 to 22,000 species worlwide, we have to multiply those numbers by 328.35 to know the total amount of insect species:

15,000 x 328.35 = 4,925,250

22,000 x 328.35 = 7,223,700

There are 4,925,250 to 7,223,700 insect species worldwide.

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
