It would be 9 buddy. Negative divided by negative turns into positive. 45 divided by 5 is 9.
Answer is 40. A triangle equals 180 so all you do is subtract 65 and 75 from 180 to get your answer.
Answer:
(9, -5)
Step-by-step explanation:
The vector AC has coordinates (27, -18), because:
21 - (-6) = 27
-13 - 5 = -18
If the ratio of AB to BC is 5 to 4, it means that
AB = [5/(5+4)]AC = (5/9)AC
Therefore, we have
AB = (5/9)AC = (5/9) (27, -18) = (15, -10)
Which means that:
xB - xA = 15 <=> xB - (-6) = 15 <=> xB + 6 = 15 <=> xB = 9
yB - yA = -10 <=> yB - 5 = -10 <=> yB = -10 + 5 <=> yB = -5
So B has coordinates (9, -5).
Hello!
To find how many times greater his average is, we just divide.
185.4/122.9≈1.51
Therefore, his average is about 1.51 times greater than Lola's.
I hope this helps!
