42000 = 2^4*3*5^3*7, so has 9 prime factors
The player who plays 9th will lose. If only 2 people are playing, that is the person who takes the first turn. The second player in a 2-person game with this starting number will always win.
Answer:
7 people
Step-by-step explanation:
(21 cookies)/(3 cookies/person) = 7 person
_____
If you're really challenged figuring this out, you can count out 21 of some object—such as pennies, scraps of paper, or even cookies—and deal them into piles of 3 each. Then count the piles. Working with actual physical objects can often give you mathematical insight not obtainable any other way.
Each pile subtracts 3 from the original amount. We use the arithmetic operation "division" to simplify repeated subtraction.
Knowing number facts such as 3×7 = 21 is very helpful to solving problems of this nature.
First rewrite as y = ..., just move the +3 to the other side (sign flips):
y = -3.
Then replace y by f(x):
f(x) = -3.
This is a straight line at y=-3.
Answer B.
Is there a number before the slash?
8: 17/24
9: 7/48
10: 5 1/4
11: 1.75
