Answer:
Volume = ⅓n²(n-1) or ⅓(n³ - n²)
Step-by-step explanation:
Given
Solid Shape: Right pyramid
Edge= n units
Height= n - 1 units
Required
Volume of the pyramid
The volume of a right pyramid is
Volume = ⅓Ah
Where A represents the area of the base
h represent the height of the pyramid
Since it has a square base;
The area is calculated as follows
Area, A = edge * edge
A = n * n
A = n²
Recall that
Volume = ⅓Ah
Substitute n² for A and n - 1 for h
The expression becomes
Volume = ⅓ * n² * (n - 1)
Volume = ⅓n²(n-1)
The expression can be solved further by opening the bracket
Volume = ⅓(n³ - n²)
Hello! So, to find the mass of the bag of rice in kilograms, you must do 3.18/2.2. 3.18/2.2 is 1.4454 and other numbers or 1.45 when rounded to the nearest hundredth. The bag of rice weighs about 1.45 kilograms.
The answer is the last choice. (a, b), in this question, means the domain or range is from a to b, exclusive. When you use ∞, you would always use the exclusive.

Answer:
I believe that Tony will have to work 16 or 17 hours to have enough money to buy the TV
Step-by-step explanation:
$276.99 - 135 = $141.99
$8.50 x 8 = $68
$8.50 x 16 = $136
$8.50 x 17 = $144.50
$8.50 x 33 = $280.50
$136 < $141.99 $144.50 > $141.99
$8.50 x 16 or $8.50 x 17
Check to see if the numbers are correct.
If they are you will have to make a choice.
I hope this helped. ☺
