A leaking faucet drips into a bucket. The faucet drips at a constant rate. The level of water in the bucket rises
Sveta_85 [38]

Answer:

The per hour rate is 0.5 inches per hour

Step-by-step explanation:

Here, we want to calculate the rate at which the level of the water increased

Mathematically, we can get this by dividing the amount of increment by the time it took

That would be 3 inches divided by 6 hours

= 3/6 = 0.5 inches per hour

Prove that for all n in the naturals, n(n+1)(n+2) is divisible by 3
DerKrebs [107]
By induction:

It's true for n=1, since 1\cdot2\cdot3 clearly contains a factor of 3.

Suppose it's true for n=k, that k(k+1)(k+2) is divisible by 3. Then

(k+1)(k+2)(k+3)=\dfrac{k(k+1)(k+2)(k+3)}k=\dfrac{3m(k+3)}k

where m is an integer. This reduces to

\dfrac{3m(k+3)}k=3m+9\dfrac mk

and both terms are clearly multiples of 3. We know that \dfrac mk is an integer since we had set m=k(k+1)(k+2) previously, which implies m is a multiple of k. So the statement is true.

You are designing a container in the shape of a cylinder. The radius is 6 inches. You want the container to hold at least 324π32
Volgvan
The least possible height is the height of the cylinder when the volume is 324π cubic inches. To determine that height, we use the formula for the volume of a cylinder. We do as follows:

Volume = πr^2h
324π = π(6)^2(h)
h = 9 inches

Find angle sum therom ​
cluponka [151]

Answer:

y = 120°

Step-by-step explanation:

angles in a triangle add up to 180 degrees

180 - (87 +33) = 60

x = 60 degrees

angles on a straight line add up to 180 degrees

180 - 60 = 120

y = 120
