Step-by-step explanation:
B False
It is equal to
or
n!/k!(n-k)!
1/3 = 4/12
1/4 = 3/12
7/12 they ate
12-7=5
5/12 is left
Answer:
686 crystals.
Step-by-step explanation:
You can set up an algebraic equation to find the answer.
Let x represent the number of crystals Lily uses.
The question is asking how many crystals it will take to raise 6,174 zombies, when each crystal raises 9.
9x = 6174
x = 6174 / 9
x = 686
That means it will take Lily 686 dark power crystals to raise 6,174. That's a lot of dark power!
Hope this helps!
The answer is A. Make sure to do multiplication/division first then add/subtract.
Answer:
9.7cm
Step-by-step explanation
According to the sine rule;
a/sinA = c/sinC
8/sin55 = c/sin82
Cross multiply
csin55 = 8sin82
c(0.8192) = 8(0.9903)
c = 8(0.9903)/0.8192
c = 7.9221/0.8192
c = 9.67
Hence the value of c to the nearest tenth is 9.7cm
