What is 3 7/8 multiplied by 2 as a mixed number or fraction?

Anwer: 7 3/4

Step-by-step explanation:

[(3*8)+7]/8    denominator * whole number + numerator

                    3 7/8  can be rewritten as 31/8

                     all over the denominator of 8

(31/8) * 2        Now you multiply by 2

(31/8) * 2/1      converting the whole number 2 to a fraction (anything divide     by one is the original number)

(31*2)/ (8*1)         (numberator *numberator) / (denominator * denominator)

=62/2  multiply the tops, multiply the bottoms

==31/2   gives you an improper fraction

=7 3/4   convert to mixed number form

the probability is 0

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
