Answer:
So I'm not entirely sure about this one, but I believe he gained 0.21 pounds each day for 30 days
Step-by-step explanation:
Since Cam was born weighing 8.6 pounds and after 30 days weighed 14.9, subtract 14.9-8.6 to find how much he gained.
14.9 - 8.6 = 6.3
Now that we know how much he gained, we have to find out how much he gained per day for 30 days. To do this, divide 6.3 by 30
6.3 / 30 = 0.21
To make sure this answer is correct, multiply 0.21 by 30 and add that to 8.6. It should equal 14.9.
I hope this helps!
The answer is 4260, you can do 200 plus 60, then add to 4000
This is already written in scientific notation, but if you are asking what the answer would be written out it is: 400000
A bag contains three red marbles, six blue marbles, and three yellow marbles.
therefore total no. of marbles = 3 + 6 + 3 = 12
total no. of red marble = 3
therefore probablity of selecting one red marble is 3/12 = 1/4
again total no. of blue marbles is 6
therefore probability of selecting one blue marble is 6/12 = 1/2
now total probability of selecting one red ball replacing it then selecting one blue marble is. 1/4 * 1/2 = 1/8
