We get all these to have the same denominators for all the fractions.
2*2/9*2 = 4/18
1*2/9*2 = 2/18
1*3/6*3 = 3/18
Now we can add all the numerators.
4/18 + 2/18 + 3/18 = 9/18
Simplify our answer by dividing both numbers by 3, then by 2.
9/3 and 18/3 = 3/6= 1/2
Our final answer is 1/2
Let x be the length and y be the width2x + 2y = 40x + y = 20change that into y = mx + b formy= 20 – x
Area =xy = x (20-x) = 20x - x^2Area=-x^2+20xcomplete the square:Area=-(x^2 – 20x + 100) +100=-(x - 10)^2 + 100This is an calculation of a parabola that opens downward with vertex at (10,100), which means maximum area of 100 happens when x, the length=10)Dimensions of the rectangle with maximum area? 10 yds. by 10 yds., a square.
Answer:
Average cost per litre of diesel = rs 8.00
Step-by-step explanation:
Amount spent on diesel each year = rs 4000
Price of a litre of diesel in the first year = rs 7.50
Price of a litre of diesel in the second year = rs 8.00
Price of a litre of diesel in the third year = rs 8.50
Average cost per litre of diesel = 
where n is the number of years.
Average cost per litre of diesel = 
= 
= 8
Average cost per litre of diesel is rs 8.00
So that he buys an average of 500 (i.e
) litres every year.
