Answer:
62 2/5
Step-by-step explanation:
62 is just the whole number and then you have 4 tenths, which is 4/10 which can be simplified to 2/5, so it's 62 2/5
In think you actually wanted the answer to the division of 455 by the number 67.
455/67 = 6.791.
For dividing such large numbers, try to go step by step. In this case try the multiplying 67 by 1 first, then by 2, then by 3, then by 4, then by 5, then by 6 and lastly by 7. When you multiply 67 by 7, then you will get 469. So this will show you that you cannot go beyond multiplying with 6. When you multiply 67 with 6 you get 402. hen again try multiplying the remainder and proceed accordingly.
Answer:
Length of the rectangle = 9.58 feet and width = 27.14 foot
Step-by-step explanation:
Let the length of the rectangular area is = x feet
and the width of the area = y feet
Area of the rectangle = xy square feet
Or xy = 260
y =
-------(1)
Cost to fence the three sides = $3 per foot
Therefore cost to fence one length and two width of the rectangular area
= 3(x + 2y)
Similarly cost to fence the fourth side = $14 per foot
So, the cost of the remaining length = 14x
Total cost to fence = 3(x + 2y) + 14x
Cost (C) = 3(x + 2y) + 14x
C = 3x + 6y + 14x
= 17x + 6y
From equation (1)
C = 
Now we take the derivative,
C' = 17 - 
To minimize the cost of fencing,
C' = 0
17 -
= 0
= 17


x = 9.58 foot
and y =
y = 27.14 foot
