My last question ! an alloy is a mixture of metals. suppose that a certain alloy is made by mixing 50 grams of an alloy containing 12% copper with 78 grams of an alloy containing 92% copper. answer the questions below. do not do any rounding. a) how many grams of copper are in the resulting mixture? b) what percentage of the resulting mixture is copper?

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

a) 0

step-by-step explanation:

i^413 x i^0 = 0 as any number multiplied by a zero is
