Answer:
$52.50
Step-by-step explanation:
What you do is you move the decimal two times to the left from 75%.
0.75*?=?
Take the orginal price and multiply ($30) by 0.75.
0.75*30= $22.50
Take 22.50 and add that to your original amount.
$22.50+$30= $52.50 or $52.5
Let's assign some random values to it, and say 1 unit of petroleum costs 100 bitcoins, because we all know bitcoins are the best currency :P
If the price goes up by 10%, it is now 100*1.1 = 110bitcoins for 1 unit.
However he's only getting 0.9 units now, so multiplying 110 by 0.9 gives us 99 bitcoins. His petroleum bill used to be 100 (which is why I picked 100 as it's easier), and now it is 99. Therefore his petroleum bill has reduced by 1%

Step-by-step explanation:
Answer: length = 28 meters
Width = 15 meters
Step-by-step explanation:
Let L represent the length of the rectangular garden.
Let W represent the width of the rectangular garden.
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(L + W)
The rectangular garden is enclosed with eighty-six meters of fencing. This means that
2(L + W) = 86
Dividing through by 2, it becomes
L + W = 43- - - - - - - - - - - -1
The garden is thirteen meters longer than it is wide.. This means that
L = W + 13
Substituting L = W + 13 into equation 1, it becomes
W + 13 + W = 43
2W + 13 = 44
2W = 43 - 13
2W = 30
W = 30/2
W = 15
L = W + 13 = 15 + 13
L = 28
I believe it’s a circle because all of the others have points that can result in a positive and rations number
