First find out 3 to the power of 6 which is 729 then divide by 3 which is 243
then find out what's the power of -2 to 243 which is 0.00001693508
Answer:
15 grams .
Step-by-step explanation:
We need to multiply the percentage as a decimal (0.30) with the amount of chocolate (50 g):
0.30*50 = 15 g
There are 15 grams of cocoa in the chocolate bar.
Angle x is 33 degrees and angle y is 57 degrees i think
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
