Answer:
2520 ways
Step-by-step explanation:
We can solve this problem with 3 combinations:
First the teacher needs to give 3 fruit snacks to 10 students, so we have a combination of 10 choose 3: C(10,3) = 10! / (3! * 7!) = 120
Then, she needs to give 2 teddy grahams to 7 students (3 already got a snack), so a combination of 7 choose 2: C(7,2) = 7! / (2! * 5!) = 21
The, she gives the 5 granola bars to the other 5 students, so a combination of 5 choose 5: C(5,5) = 1.
Now we just need to multiply the combinations to find the result:
C(10,3) * C(7,2) * C(5,5) = 120 * 21 * 1 = 2520 ways
Answer:
The slope of FG is -1
Step-by-step explanation:
Given
Square EFGH
EF: 
Required
Determine the slope of FG
First, we calculate the slope of EF

Make y the subject


The general equation has the form: 
Where

Compare
to 

<em>From the name of the square EFGH, we can conclude that EF and FG are perpendicular</em>
<em />
The relationship between perpendicular lines is:

Where
-- Slope of EF
and
m2 = slope of FG
Substitute 1 for m1 in 


<em>Hence, the slope of FG is -1</em>
Answer:
I believe the answer is 7 and a half days
Step-by-step explanation:
15*
= 7.5
If you take the 15 and multiply it by the
you will get 7.5. Even if you divide the 15 by
Apologies if this is wrong. But I think this is the answer.
Hope I could help :)
