Ican imagine you notice that the air temperature dropped 10 degrees every 1000 meters increase in elevation write a multiplication expression to represent the decrease in temperature if you hike up the mountain 3000 meters

this is your expression

x / 1000 * -10

so x is the amount hiked so in this situation x = 3000

3000/1000 * -10

3 * -10

-30 degrees

the temperature wouldve dropped 30 degrees

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.

0.02

step-by-step explanation:

time of 9 192 631 770 periods of the radiation corresponding to the transition between the 2 hyperfine levels of the ground state of the caesium 133 atom at 0 k (but other seconds are sometimes used in astronomy)
