When d=46 the expression has a greater value.
Percent change=(change/original) tiimes 100
change= |original-new|
so
12 to 36
|12-36|=|-24|=24
so
pcercent change=100 times (24/12)=100 times 2=200%
50 to 35
|50-35|=|15|=15
percent change=100 times (15/50)=100 times 100 times 0.30=30%
10 to 24
|10-24|=|-14|=14
percent change=100 times (14/10)=100 times 1.4=140%
16 to 44.2
|16-44.2|=|-28.2|=28.2
percent change=100 times (28.2/16)= 100 times 1.7625=176.25%
answers are
-12 inches to 36 inches: 200%
-50 punds to 35 pounds: 30%
-10 gallons to 24 gallons: 140%
-16 centimeters to 44.2 centimeters: 176.25%
Answer:
I believe it is 49.425
Step-by-step explanation:
You just add all the numbers then divide it by how many numbers there are.
Whatever% of anything is just (whatever/100) * anything.
let's say we'll add "x" cups of pure vinegar, pure vinegar meaning is 100% vinegar.
how much vinegar is there in "x" cups of 100% vinegar? well (100/100) * x, or just "x".
how much vinegar is there in 10 cups of 10% vinegar? well, (10/100) * 10, or just 1.
say after adding the "x" cups to the 10 cups, we end up with "y" cups, of 50% of vinegar.
how much is 50% of y? well, (50/100) * y or 0.5y.
bearing in mind that x+10 = y, both cups amounts added up, and that x+1=0.5y, both vinegar amounts added up, thus
16.79+28.49=45.28
50-45.28=4.72
