Working step by step I first see all my different groups then add them all together
so
12 - cats
15 - dogs
6 - both
9 - neither
12 students + 15 students + 6 students + 9 students = 42 students
therefore 42 students are in the class
16 + 10 + 3 + 12 = 41
I’m sorry if i got it wrong!
Answer:

Step-by-step explanation:
2/8 * 7
2/8 will simplify
Divide the top and bottom by 2

4 goes into 7 once with 3 left over
1 3/4
Answer:
i think it weak positive im not sure
Step-by-step explanation:
The force being exerted by the cord is m(a+g) if the bucket is being accelerated upward.
If T = 70 N, then <span>a=70N/5.2kg−9.8m/<span>s2</span>=3.66m/<span>s2</span></span>is the maximum acceleration that it could have.
Starting from rest, <span>Δy = 1/2a<span>t2</span>→ t = </span>√2Δy/a = <span>√</span>2∗12.5/3.66 = 2.61s
