Answer:
There are 10 counters in the bag and you want the 4
As their is only one for the probability is
1/10
There are now 9 counters left in the bag.
You only want the even ones , which are 2 6 8 and 10 ( four has been taken out)
There are only four even counters in the bag of nine counters so the probability is
4/9
As you want both of these to occur, you need to multiply them
1/10 x 4/9 = 49/90

Answer:
If the long side is down then the length of the base is 81 sq.m.
If the short side is down then the length of the base is 20.25 sq.m.
Step-by-step explanation:
162/4 is 40.5 that means if this were a square it would be 40.5 sq.m. On each side, if the base is longer you multiply 40.5 by 2 (or whatever youre supposed to honestl) and if the base is shorter you divide by 2 (or whatever you were supposed to)
I think it’s 0.54. But I’m not sure if that’s right
21-6n+2(2n-5)-3n
First, multiply 2x2n and 2x-5
21-6n+4n-10-3n
Then rearrange the terms
4n-6n-3n+21-10
Then combine like terms
-5n+11

Answer:
10 friends
