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.
Answer:
72 cubes
Step-by-step explanation:
Top view of the rectangular prism shows the unit cubes arranged in two rows along the length.
In each row number of unit cubes arranged = 9
Right view side of the prism shows the unit cubes arranged in two columns.
Number of unit cubes in each column = 4
Total number of cubes arranged in the prism = (Number of cubes in each row × Number of cubes arranged in two columns) × Number of columns
= (9 × 4) × 2
= 72
Therefore, number of cubes filled completely in the prism with no gaps = 72
-3-8X≥9
Add 3 on both sides.
-8X≥12
Divide by negative 8 and flip the sign.
X≤-1.5
There isn't a number behind five, so I would just keep as is.
I hope this helps!
