Answer:
Yes, she is.
Step-by-step explanation:
If you add 1 hour and 50 minutes to 12:30, you get to 2:20. 16:05 is 4:05, so yes she is on time.
So if you draw it, the diagonal makes a right triangle. To find the diagonal, use the pathagorean theorem. a^2+b^2=c^2 so 900 + 1600 =c^2 So solve that: 2500=c^2 so the length of c, the diagonal is 50. BE is half of BD, so you divide 50 by two.
The answer is BE = 25
b. Any two negative numbers when multiplying gives positive answers which are never between negative numbers. -9*-3=27
c. same logic, positive answer so never less than either negative number.
