Answer:
1.) 2.5 meters a second
Step-by-step explanation:
1 min 12 seconds is 72 seconds. 28 meters on 72 seconds. 28×2.5=72
The answer is $85.50
57 x 50% or 57 x .5 = 28.50
Add $28.50 to $57 and you get $85.50
If there are 12 items adding up to 60%, we want to know how many items more it will take to equal 100% So set up this equation 12/x = .6 then solve for x. x=12/.6 x = 20 now that we know the total you can subtract 12 from 20 and get 8, that is the number of items left on the list.
