Answer:
F=121.61 gr,
Step-by-step explanation:
we see that it is a problem of proportion, so then if the total mass of the sample is the sum of M plus fluorine
the sample weighs 1.38gr M + 0.71gr F = 2.09, where M y F represent :
M=1.38*100/2.09 = 66.02% and
F=0.71*100/2.09 = 33.97%, also
in 358 gr. * 0.3397F = 121.61 gr F
Answer:
9 weeks
Step-by-step explanation:
Knowing that the "q" is the total number of quizzes, you can set the equation equal to 12, and solve for w.
12 = w + 3 Subtract 3 both sides
9 = w
Answer:
N represent 5 games
Step-by-step explanation:
Firstly, we need to get the total number of games. From the information given, the total number of games is 9 + N = (9 + N) games
The total number of games won is (2 + N) games and this is exactly half of the total number of games.
This mathematically means
2(2 + N) = (9 + N)
4 + 2N = 9 + N
2N - N = 9 - 4
N = 5 games
