Step-by-step explanation:
To find the average weight, you need to add all of the numbers and then divide them
I'll start off by doing this:
1/8+1/8 = 2/8
1/4+1/4+1/4+1/4 = 1
3/8+3/8 = 6/8
1/2+1/2 = 1
then I'll add them together:
2/8+6/8 = 1
1 + 1 + 1 =3
now we need to divide the amount of numbers. the amount of sandwiches weighted (10) will have to be divided
therefore, we get 3/10. because this can't be simplified, this will be your final answer.
We know there is 57 members are in the math club and there is twice as many sixth grades than the seventh. To find out how many sixth graders are in the club, we do:
x = seventh graders
2x = sixth graders
2x + x = 3x
57=3x
57 ÷ 3 = 3x ÷3
19 = x
So there is 19 seventh graders and 19×2= 38 sixth graders

Answer:
3/20
Step-by-step explanation:
The total number of marbles is
3 red marbles+ 2 blue marbles+ 5 green marbles = 10 marbles
P(1st marble is red) = red marbles/total
=3/10
We replace the marble so there are still 10 marbles in the bag
P(2nd marble is green) = green marbles/total
=5/10 = 1/2
P(1st red, 2nd green) = P(1st marble is red) * P(2nd marble is green)
=3/10 *1/2
=3/20
