Here is my approach to this problem. :)
Well here is your first part...
3.56×10^-5
Its negative so go to the left:
=.00000356
Here is your second part...
4×10^4×3×10^4
There both positive so go to the right
=40000 =30000
Then you multiply....
40000×30000=
= 1200000000
Here's your third part...
You need to divide 31 by 117
31÷117=
=0.2650%
Answer:
4%
Step-by-step explanation:
8 divided by 200 equals 0.04
0.04 times 100 equals 4
Therefore 4 percent of the people had a mild allgergic reaction.

9. Angle LSM and Angle 2 are pair of vertical opposite angles which are equal.
10. Angle forming vertical pair with Angle 1 is Angle LSO (Angle 3).
