A cylindrical water towers has a diameter of 15 meters and a height of 5 meters. About how many gallons of water can the gallon contain?

Answers

Answer:

233445.54 gallons

Step-by-step explanation:

Given data

Diameter= 15m

Radius= 7.5m

Height= 5m

Let us first find the volume

the volume of a cylinder is given as

V= πr^2h

substitute

V= 3.142*7.5^2*5

V= 3.142*56.25*5

V=883.6875 m^3

Hence the volume in gallons is

Leticia bought a new tablet for $425. She had to pay a sales tax of 8%.

What was the total cost after sales tax that Leticia paid for the tablet?      Total: $


​

Answers

Sale Tax: $34
Total: $459

Step to solve:
To find sale tax you would need to multiple 425, the cost of the tablet by 8% or 0.08 in decimal form to get the answer 34.

To find the total add the sale tax, 34, and the cost of the tablet, 425, to get the total, 459 dollars.

Which equation can be used to find the value of x?
109=180
x+42=67
x=180-109
42+67-x=180

Answers

Answer:

C

Step-by-step explanation:

We know every triangle equals 180 so were just going to take 180 - 42 = 138 then were going to do 138 - 67 = 71  we can check our work by doing

42 + 67+ 71 = 180. We also know 67 + 42 = 109.

Lets look at our answers;

A. 109 = 180 + x  When solved it gave me; x = -71. We got a positive 71 so this is incorrect.

B. x + 42 = 67   When solved it gave me;  x = 25, which is incorrect.

C. x = 180 - 109 When solved it gave me; x = 71

D. 42 + 67 - x = 180 When solved it gave me; x =  - 71

Therefore the answer is C.

Read the following poem:



This band was all my idea

I'm the one that found all the members

I'm the one that picks all the music

And I'm the superstar lead singer



So when our drummer said his cousin, Mae

Had a really awesome voice

Everyone else wanted to meet her

So I really was given no choice



We had her in for an audition

And I'll admit she sang like a bird

But of course I felt a bit threatened

And inside me jealousy stirred



Their plan was that she'd sing with me

But I said, no, she could do something else

But once again I was outvoted

So I kept my complaints to myself



And I grumbled inside on the bus ride

To our very first show with Mae

And I refused to wish her good luck

As I stomped like a brat to the stage



But when Mae joined me on our first song

Something happened with her and me

Our voices twined like flowering branches

In perfect harmony



Afterwards I was almost ashamed

That I had tried so hard to obstruct her

because adding some great to a really good thing

Can only make that thing better.
