23x36=828
This should be your answer
Just pretend it’s a 3d right angle triangle and find the length of the hypotenuse.
d = sqrt(6^2 + 10^2 + 15^2) = 19
Answer:
I might be wrong but I am pretty sure the answer is (3,0,5)
I'm back so
80% of 12=9.6 grams=gold so
so she wants to add to the alloy to make the gold 92.5% gold so
I'm not sure how to do A or B but I think the answer to B is 2.4 grams
C. so the jewler has 2.4 grams of alloy
we must find out when 2.4=7.5%, what is 100%
so if 2.4=.075x then 24=0.75x then 32 grams=100 %
so 32-2.4=29.6 grams
29.6/32=0.925 or 92.5%
this is not the legit way to do it
