Answer: 210
Step-by-step explanation:
We know that the number of combinations of n things taken r at a time is given by :-
So, number of ways to select 3 plants out of 7 = 
Also number of ways to arrange them in 3 positions = 3! = 6
Now , total number of arrangements with 1 plant in each spot = (number of ways to select 3 plants out of 7) x (number of ways to arrange them in 3 positions)
= 35 x 6
=210
Hence, required number of ways = 210
Answer:
25 minutes
Step-by-step explanation:
Let the amount of time, in minutes, be x.
For Container A, we can write:
200 + 6x [since it has 200 and is being filled with 6 per minute]
For Container B, we can write:
500 - 6x [since it has 500 and is being drained with 6 per minute]
To find, we equate them and solve for x:
<em>So, in 25 minutes (m), the two containers will have same amount of water</em>
Answer:
3 15/16
Step-by-step explanation:
The ruler has been turned to the inches
So what you are measure is in between 3 and 4 so 3
And between 3 and 4 there are 16 small lines and what you are measuring ends at 15
So the answer is 3 15/16
1) The slope is 2
You can find this by finding this rise over run which is essentially counting from one point to the next
2) y intercept is 6
You can tell because when the x axis is at 0, the point is at 6 for the y-axis
3) Now that you have the slope and y intercept the answer is:
Y=2x+6
