Bob equals 6 times more than Tom.
6×t=B
(B means Bob)
Answer:
O
Step-by-step explanation: Just divide each kilometer by hrs for each one (sry if this doesn't make sense) O: 60 divided by 5= 12 M: 80 divided by 5=16 N: 110 divided by 5= 22. Therefore O= 12 kilometers per hour, which means its the slowest ( I did this question in khan and got it right)
Answer:
34.6 units
Step-by-step explanation:
Given data
A (-5, -5), B (3, 4)
distance is
![d= \sqrt((x_2 - x_1)^2 + (y_2 - y_1)^2)\\\\d= \sqrt((3 +5)^2 + (4 +5)^2)\\\\d= \sqrt((8)^2 + (9)^2)\\\\d= \sqrt(64 +81)\\\\d= \sqrt(145)\\\\d= 12.04](https://tex.z-dn.net/?f=d%3D%20%5Csqrt%28%28x_2%20-%20x_1%29%5E2%20%2B%20%28y_2%20-%20y_1%29%5E2%29%5C%5C%5C%5Cd%3D%20%5Csqrt%28%283%20%2B5%29%5E2%20%2B%20%284%20%2B5%29%5E2%29%5C%5C%5C%5Cd%3D%20%5Csqrt%28%288%29%5E2%20%2B%20%289%29%5E2%29%5C%5C%5C%5Cd%3D%20%5Csqrt%2864%20%2B81%29%5C%5C%5C%5Cd%3D%20%5Csqrt%28145%29%5C%5C%5C%5Cd%3D%2012.04)

Hence the perimeter
= 12.80+9+12.80
=34.6 units
