In order to find the percent error, we need to first find the difference between what was expected and what is actually costed. We do this by subtracting:
So now we know that the expected amount was off by $63. To find the percent error, we need to take this $63, and divide it by the amount that was estimated. Let's do that now:
However this is in decimal form. We need to multiply by 100 in order to get it in a percent:
Now we know that
the percent error of the hospital bill estimate is 13.64%.
If 532,475 warranties were given, it means that 532,475
warranties were sold. The gross profit should be, 532,475 * $830 = $441954250.
But then, this would still be subtracted with 12% of the warranties since they
gave it back to the customers. Hence,
Profit = $441954250 – 0.12(532,475)($225)
Profit = $427,577,425
Your equation is like so A x 2 x 3 = 132
A is the length of your first string B is the length of your 2nd string (A x 2) and C (3) is the length of your 3rd string which is (A x 3).
A x 2 x 3 = 132
/3 /3
A x 2 = 44
/2 /2
A = 22.
A(22) x 2 x 3 = 132. 22 x 2 is 44. 44 is the length of line 2. 22 x 3 is 66, 66 is the length of line 3. 22 + 44 + 66 = 132. 66 is the length of your longest piece.
The amount that needs to be changed = 6.60 pounds
The ratio in which the given amount needs to be divided = 5:6
Let us assume the common ratio to be = x
Then
5x + 6x = 6.60
11x = 6.60
x = 6.60/11
= 0.6
So
The ratio for dividing 6.60 in the ratio 5:6 will be = 5 * 0.6: 6 * 0.6
= 3:3.6
This is the simplest way to to find the ratio of the amount 6.60 pounds. I hope you have understood the procedure.
This is the concept of algebra, given that the length of the rectangle is 5x-2 and the width is 3x+1, the perimeter is 2(5x-2)+2(3x+1). To get the total distance Zohar needs to cut with the scissors, we substitute the value of x=4 in the expression for perimeter. Hence we shall have:
2(5x-2)+2(3x+1)
=2(5*4-2)+2(3*4+1)
=2(20-2)+2(12+1)
=2(18)+2(13)
=36+26
=62 cm
The answer is 62 cm
