An average person in the united states throws away 4.5 × 10–2 kg of trash per day. in 2013, there were about 3.2 × 10-6  people in the u. s.  about how many grams of trash were thrown away in the united states in 2013?  

Solution: We are given:

On an average, one person in United states throws away g/day

In 2013, the population in United states

So in 2013, g/day of trash was thrown away.

In 2013, the number of days = 365

Therefore, in 2013 the amount of trash thrown away is:

g

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

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?
