Answer:
I think it's D.145
Step-by-step explanation:
To answer this, you will determine what fraction of the original rocks are silver by using the information about the other two colors.
If 2/3 of them area purple, than 1/3 are not.
If 3/4 of the remaining 1/3 is blue, than 3/4 x 1/3 = 3/12 of then are blue.
2/3 are purple, 3/12 of them are blue, the remaining is silver,
1 - 2/3 - 3/12
1 - 8/12 - 3/12 = 1/12
1/12 of the rocks are silver. If 3 are silver, write an equation that needs solved.
1/12r = 3
r = 36 rocks
There were 36 space rocks in total.
It’s your mom if it’s not try 1 plus 1 and divide it by pie and dive your current answer it’s 4
Since you OWE,
the best integer is
-20
I think starting from the top it would go as follows
9/36, 27/36, 32/36 , 4/36
b.) 9/36
c.) I really don't remember how to do the "order doesn't matter" thing anymore, so idk. my best idea is for you to look up the formulas for permutation and combinations. I know it has to do with that
