Answer:
-2 and 2/3
Step-by-step explanation:
(2/3) / (-1/4) is equivalent to (2/3) x (-4/1)
This equals -8/3, of which simplifies down to -2 and 2/3
To calculate percent change.... First work out
the difference (increase) between the two numbers you are comparing. Then
divide the increase by the original number and multiply the answer by 100.
(if your answer is a negative number then that is a percentage decrease.)
The formula for percent change:
((y2 - y1) / y1)*100 = your percentage change.
Problem work:
y1 =16
y2 = 44.2
( 44.2-16/16) x 100
(1.7625) x 100
So the percent increase (percent change) will be 176.25%
hope this helps!
Answer:
6748'
Step-by-step explanation:
The long diagonal is the third leg of a triangle with the given side lengths and an angle between them that is the supplement of the given angle. Its length can be found from the Law of Cosines.
a^2 = b^2 +c^2 -2bc·cos(A)
a^2 = 3473^2 +4822^2 -2·3473·4822·cos(180° -72.23°)
a^2 = 45,535,553.83
a ≈ 6748.004
The longer diagonal is about 6758 feet long.
