Answer:
L=8 and J=11
Step-by-step explanation:
If Lee is L and Joanna is J we get: L+J=19.
And since Joanna has 3 more than Lee we get: J=L+3
When we substitute J for L+3 we get: 2L+3=19
When we solve we get: L=8
Finally, since J=L+3 we get: J=11
Answer:
250 green marbles
Step-by-step explanation:
We know that there are 25 green marbles in a bag of 40 marbles. Using this, we can say that the probability of pulling a green marble out of the bag is 25/40, or 5/8. To find out how many green marbles Shawna should expect to pull out of the bag after 400 trials, we have to multiply the amount of trials (400) by the probability of pulling out a green marble (5/8).
400 × 5/8 = (400 × 5)/8 = 2000/8 = 250
Shawna should expect 250 green marbles after 400 trials.
I hope you find this helpful. :)
3 feet = 36 inches
36 x 6 x 2.4 = 518.4 cubic inches
1 cubic foot = 1728 cubic inches
518.4/1728 = 0.3 cubic feet
0.3/0.15 = 2
