What is the sum of any rational number and it's opposite

Answers

To figure out this problem, you can look at formulas, or you can try out a few problems. There are many people that prefer one or the other in my class, so I will show you both. :)

Before I show you either of these, I'm going to define rational numbers and explain some things so that you can understand why we do what we do. Make sure to remember things like this because when you get to algebra (I'm in algebra), you need to know all of this stuff!  :)

A rational number is any number that can be written in a over b form (a/b) or as a fraction. A rational number can be positive or negative because you can put positive and negative numbers into a fraction. Decimals can also be rational numbers because things such as .3 can be written as 3/10. So, depending on what number you have, there is always an opposite. 

To find an opposite number, you have to basically find the absolute value (how far the number is from zero), double that number, and add it from the original number. Or, if you want to make it worlds easier, you can just make the number the opposite inverse. So, if it is -4, the opposite is 4. If the number is 7, then the opposite is -7. What is the sum between both of those examples? Zero.

Here is the formula: a+(-a)=0, (-a)+a=0
Here is some examples: (-5)+5=0, 8+(-8)=0

Thanks so much for the opportunity to answer your question. I hope this helped! :)
It's 0.

a+(-a)=a-a=0

Hannah is having her bedroom painted. Interior Designs of Royal PalmBeach charges $60 for inspection and $40 per hour for painting.
Wellington's Splash of Color charges $70 per hour for painting, but no
inspection fee. Which of the following are true? Select all that apply. *

If it takes 7 hours to paint Hannah's room, Interior Design will be cheaper.


If it takes 3 hours to paint the room, both companies will charge the same amount.

If it takes 10 hours to paint Hannah's room, Splash of Color will cost at least $200
more than Interior Design.


Splash of Color will always be cheaper.

Answers

he read 2/15 of the book on Wednesday

1/5=3/15
2/3=10/15
3/15+10/15=13/15
15/15-13/15=2/15

What is the volume of a cylinder, in cubic ft, with a height of 14ft and a base diameter of 12ft? Round to the nearest tenths place Answer: V= ft 3

Answers

Final answer:

The volume of the cylinder is approximately 1582.2 cubic feet when rounded to the nearest tenths place.

Explanation:

To find the volume of a cylinder, you can use the formula:

Volume (V) = π ×  r² × h

Where:

V is the volume of the cylinder.

π (pi) is approximately 3.14159.

r is the radius of the base.

h is the height of the cylinder.

In this case, the base diameter is given, but you need to find the radius, which is half of the diameter:

Radius (r) = Diameter / 2 = 12 ft / 2 = 6 ft

Now, you can plug these values into the formula and calculate the volume:

Volume (V) = π × (6 ft)² ×  14 ft

Volume (V) = 3.14159 ×  36 ft² × 14 ft

Volume (V) ≈ 3.14159 ×  504 ft³

Volume (V) ≈ 1587.82336 ft³

Rounding to the nearest tenth, the volume of the cylinder is approximately 1587.8 cubic feet
