Answer:

The volume of the sphere is V=18\pi\ ft^{3}

Step-by-step explanation:

we know that

The volume of cylinder is equal to

V=\pi r^{2}h

we have

V=27\pi\ ft^{3}

substitute

27\pi=\pi r^{2}h

simplify

27=r^{2}h

Remember that

A sphere and a cylinder have the same radius and height

so

The height of cylinder is equal to the diameter of sphere

h=2r

substitute

27=r^{2}(2r)

13.5=r^{3} -----> equation A

The volume of the sphere is equal to

V=\frac{4}{3}\pi r^{3}

substitute equation A in the formula of the volume of sphere

V=\frac{4}{3}\pi (13.5)

V=18\pi\ ft^{3}

Ieda and Thanh both offer piano lessons. Ieda charges an initial fee of $8.50 and an hourly rate of $11.00. Thanh charges an ini
Trava [24]
The price for each instructor will be the same at 3 hours. How I determined this answer:

First off, you need to add the initial price and hourly price for each person together, so you already know how much it will cost for 1 hour, including the initial fee. Here's how you do it:

Ieda: $11.00 (hourly price) + $8.50 (initial fee) = $19.50 (for 1 hour)

Thanh: $10.50 (hourly price) + $10.00 (initial fee) = $20.50 (for 1 hour)

Now that you have the price for 1 hour including the initial fee, now you need to find the price for each hour after that. Here's how I did that:

I created a graph that looked like this:

Hours:       1                 2                  3               
Ieda:      19.50          30.50         41.50
Thanh:   20.50          31.00         41.50

Here's how I figured out the price for each hour:

Ieda:

Hour 1 (including initial price):
            $11.00 + $8.50 = $19.50
Hour 2 (excluding initial price): Only add the hourly price after Hour 1!
            $19.50 + $11.00 = $30.50 
Hour 3 (excluding initial price):
            $30.50 + $11.00 = $41.50

Thanh:

Hour 1 (including initial price):
            $10.50 + $10.00 = $20.50
Hour 2 (excluding initial price):
            $20.50 + $10.50 = $31.00
Hour 3 (excluding initial price):
            $31.00 + $10.50 = $41.50

So, looking at the graph, their prices are the same once each instruction reaches 3 hours. ($41.50)

I hope I was able to help you! :)

Points J and K are midpoints of the sides of triangle FGH. What is the value of y?

The answer 

the complement of the question is 

What is the value of y?

According to the image, HKJ and FGH are similar, we can apply the theorem of thales
since GK and GF are parallels, so 

HK / HF = HJ / HG = KJ / GF and as we see on the figure, HK = HF /2, this implies  2HK =HF

HK / 2HK =  KJ / GF  it is equivalent to   1/2 = 2y+5 / 5y +3 

likewise, equivalent to  5y +3  = 4y +10, 5y-4y = 10-3, and y = 7


so the answer is 7

What is the probability that a passenger prefers to sit in front of the plane and prefers a window seat
Ksenya-84 [330]

Answer:

A

Step-by-step explanation:

This is a probability question.

We want to calculate the probability that a passenger prefers to sit in front of the plane and at a window seat.

The answer here is directly obtainable from the table. Let’s take a look at that point where we have the front and window merging. We can see that the figure here is 8

Thus, the probability that we want to calculate is this figure over the total = 8/36

= 2/9

A gas can hold 10 L of gas. How many cans could we fill with 7 L of gas?
katrin2010 [14]

Answer: It is only one can that can be filled up.

Step-by-step explanation: If 1 gas can can hold 10 L of gas and you only have 7 L then how can you fill up more than 1 gas can with only 7 L?  You don't have enough gas to fill up more than 1 gas can. So you are left with only 1 gas can filled but only with 7 L.

4(2x + 3) ÷ 5y
Murrr4er [49]
I won’t give a actual answer to the equation, because I want you and anyone else to learn it. but I do want to help!

the sum is the answer to a addition problem. that means you should choose anything that falls under that.

The term is anything that is being separated by + or - so for this, choose anything like that.

The product is the final answer to a multiplication problem.

Factor- any number leading up to a answer in a problem. Example: 3 times 4 is 12. The 3 and the 4 are the factors.

Quotient- the final answer to a division problem.

Coefficient- the number separated from the rest of the problem or the number at the beginning of the problem that stands alone. Because this one is a bit harder to explain, I’ll go ahead and tell you it is 4.

Variable- the unknown number such as y or x.




I hope this helps, and good luck!! :)
