Formula for <span>Volume of cube= 1/3 x area of base x height
</span>as base and height are the same:
So,
Base = 18 cm
Height = 18 cm
Area of base = Base^2
<span>Area of base = 18^2
</span><span>Area of base = 324 cm
</span>Putting all the values into the formula:
1/3 x 324 x 18
<span>=6 x 324 </span>
= 1944 cm^3
So according to above explanation
<span>C) 1944 cm3, is the correct answer.</span>
Answer:
y = 1 , x = 3
Step-by-step explanation:
3x + y = 10
x = 2y + 1
3(2y + 1) + y = 10
6y + 3 + y = 10
7y = 7
y = 1
x = 2(1) + 1
x = 3
Answer:
Step-by-step explanation:
3 tickets to attend an Off-Broadway show cost $81,
4 tickets cost $108; and
5 tickets cost $135.
Let the price of a ticket=k
Therefore:
Solving any of the equation above gives: x=27
We therefore have:

Let y be the total cost of x tickets
- From the above, the constant of proportionality, k=27
An equation for the relationship is therefore:
y=27x (where x is the number of tickets and y is the total costs (in $)).
