We know that the area is 20.
Since 20 is a small number: lets list out possible combinations of lengths and widths.
1 * 20
2 * 10
4 * 5
L = 7 + 3w
lets see which on makes sense.
L = 7 + 3w
20 = w7 + 3w^2
3w^2 + 7w -20 = 0
(3w - 10)(w - 2)
w can equal 10/3 or 2.
So the dimensions: are Width = 2 Length = 10
Answer:
Yes
Reason/Explanation
This equation represents a proportional relationship because the graph of the equation is a straight line passing through the origin.
Hope this helps :P
Answer:
ill edit this and Post the answer in a few m0ments .....
Step-by-step explanation:
Given => ABCD is a rectangle.
Where AB(length) = 12.5 units
AD(breadth) = 2.5 units
Area of rectangle = length × breadth
= 12.5 × 2.5
= 31.25 unit²
Hope this helps!
Question says that a bookkeeper is posting to the accounts of a manufacturer of coffee. Their accounting software deals with weights in kilograms, but the company’s handwritten accounts state that they have produced 21,560 pounds (lbs.) coffee this month.
Now we have to find about what entry in kilograms should they put into their spreadsheet.
Basically they want to convert 21560 pounds into kilogram.
We know that 1 pound = 0.453592 Kilograms
Then 21560 pound = 0.453592*21560 = 9779.44352 Kilogram
Hence final answer is approx 9779.44 Kilogram.
