Answer:
Step-by-step explanation:
Hooke's Law applies here, which is a linear relationship. It would be easier to solve this using proportions with N of force on the top and the amount of stretch in cm on the bottom. Set up with our unknown, the number of cm:
and cross multiply:
20x = 300 so
x = 15 cm
0.21
to find the percent change of something you must subtract the new-old divided by the original price.
$3.50-$2.75= 0.75
0.75÷3.50
0.2142857142857143
so we round and get
3937.01 Inch are in 100 meter
40%
Well, if 4/10 work part time, 4/10 converted to percentages is 40%.
