Answer:
42 acres to 72 acres, there is an increase of 30 acres
percentage wise
72-42=30
30/72=.4166...
therefore there is also a 41.6% increase
Step-by-step explanation:
71.42 Percentage change:×100%
Now, the change is given from 42 acres to 72 acres, therefore
Change= 72-42=30
⇒Percentage change= ×100%
= 71.42
x squared = 9 NOT x
x = square roots of 9 which is +3 or -3.
So 44% is 44/100
set it to
22/x = 44/100
cross multiply
(22* 100)/40 = x
50 = x
so
22 is 44% of 50
Hope this helps :)
If you could please make it clear I might be able to help, (that is if you've not already done it)
The rule is multiply the number in the left column by 2 and then subtract 1 to get the number in the right column.
