<span>Answer:
The multiplication factor of increase should be inverse of the multiplication factor of decrease.
e.g. Say you have a number 100.
You increase it by 25%. The multiplication factor is 5/4 i.e. when you multiply 100 by 5/4, you get 100*5/4 = 125. This is 25% more than 100.
Now you want to decrease it by a certain % such that you get 100 back.
Basically, 100*5/4 * x = 100
So x = 4/5 (inverse of 5/4)
Hence, you decrease by 20% (the multiplication factor of 20% is 4/5)
or
Use this formula: cumulative % change = a + b + ab/100
You want the cumulative change to be 0.
a + b + ab/100 = 0
If you know that you are increasing by 25% and want to find the % by which you should decrease to get the same number,
25 + b + 25b/100 = 0
5b/4 = -25
b = -20
So you need to decrease (hence you get the -ve sign) by 20%.</span>
Answer:
1/2
Step-by-step explanation:
Total number of cards in a deck = 52
Total umber of red cards = 13 + 13 = 26
P(red card)
= 26/52
= 1/2
To find the parameter you have to add the length and the width and multiply by two
And your example long is the length and wide is the width so add it and times two answer is seven
Because the semi circle is too which is what it's inside but the answer is still seven
Answer:
4.33 recurring
Step-by-step explanation:
do the inverse
11+2=13
13/3=4.33333
t=4.33333
