Find the distance between M(-1,-10) and P(-12,-3) * Round to the nearest tenth.
DedPeter [7]

Answer:

13.0 units

Step-by-step explanation:

To find the distance between two points, we use the formula

d = sqrt( (y2-y1)^2+ (x2-x1)^2)

   sqrt((-3--10)^2 + (-12--1)^2)

   sqrt( (-3+10)^2 + (-12+1)^2)

   sqrt( (7^2  + (-11)^2)

  sqrt( 49+121)

  sqrt( 170)

A warehouse worker moved 108 pallets in 4.5 hours. In minutes, what is the rate to move one pallet? The worker will be off the c
klasskru [66]

Number of pallets moved in 4.5 hours = 108

converting 4.5 hours in minutes we get,

4*60 + 0.5*60 = 240+30 = 270 minutes

So, 108 pallets were moved in = 270 minutes

1 pallet was moved in = \frac{270}{108}=2.5 minutes

As the tie will get over in 2 hours or 2*60 = 120 minutes, the number of pallets that can be moved will be = \frac{120}{2.5}= 48 pallets.

Hence, 48 pallets can be moved before quitting time.
