What is the standard form of 5.58 • 10^5?

A. 0.05800

B. 558,000

558,000

Step-by-step explanation:

First you multiple 10 by the power of 5 = 10 x 10 x 10 x 10 x 10 = 100000 x 5.58 = 558,000

three-fourths of an hour

36÷48=0.75

0.75=

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
