How many ounces of a 35 %35% alcohol solution must be mixed with 1515 ounces of a 40 %40% alcohol solution to make a 38 %38% alcohol solution?

Let be the amount of the 35% solution that will be added. The resulting solution will have a total volume of , 38% of which is alcohol. 40% of 15 is 6, so the 40% solution contributes 6 oz of alcohol. So

oz of the 35% solution need to be added.

i'm not entirely sure

step-by-step explanation:

if you ask home depot or lowe's they might be able to you out

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
