Rina draws a plan of her school on a coordinate grid. she plots the school gate at point p(-8,-1) and the library at point q(2,5). she notices that the science lab is also located on pq and is two thirds the distance from the library to the school gate. what are the coordinates of the science lab ?

The coordinates of the science lab is:

x = -14/3  ,  y = 1

Step-by-step explanation:

∵ P is (-8 , -1) and Q is (2 , 5)

∵ The point of the science lab is (x , y)

∵ The science lab point divided PQ at ratio 2 : 1 from Q (two thirds PQ)

∴

∴

∴

∴

∴ The point of science lab = (-14/3 , 1)

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
