Answer:
22
Step-by-step explanation:
The volume of a cube is given as:
Cube volume = length × length × length
Since the edges of the cube measure 3 inches, this means that the length of the cube is 3 inches, therefore:
Cube volume = 3 inches × 3 inches × 3 inches = 27 in³
The pine tree is the shape of a cone with diameter of 1.5 inches and a height (h) of 2 inches. The radius (r) = diameter / 2 = 1.5 inches / 2 = 0.75 inches.
The volume of the cone = πr²(h/3) = π × (0.75)² × (2/3) = 1.178 in³
The number of pine trees that can be made = Volume of cube / Volume of cone = 27 / 1.178 = 22.9
The number of pine trees = 22
Answer:
From the above we can roughly for an equation which is:
58.50 = Bill - (10% x Bill)
58.5 = Bill - (1/10 x Bill)
58.5 = 9/10 x Bill (Divide both sides by 9/10)
We get:
Bill = 58.5 / (9/10)
Bill = 65
Original bill is $65.

Answer:
x3 just multiply 2 x 3 and then multiply the 6 from that by 3 to get 18 and so on
Step-by-step explanation:
ez
Inlet pipe can fill the pool in 6 hours, means: every hour the pool is filled 1/6
a drain can empty the pool in 9 hours, means: every hour the pool is drained 1/9
If the inlet and the drain are both left open, every hour the pool is filled 1/6-1/9=1/18
It will take 18 hours to fill up the pool.
