The absolute value of a number is added to the original number. Kayla says the sum is always 0. Is she correct? Why

The absolute value of a number is its distance from 0. The absolute value of -4 is 4, the absolute value of 4 is 4.
-4 + 4 is 0, so she's right there; but 4, + its absolute value, 4, is 8. This means that Kayla is incorrect.

I suck at math so help me please:)
Evgen [1.6K]
Since they’re vertical we know that they’re congruent. We write the equation as 160=10x+50. Subtract 50 to both sides then we get 110=10x so now we divide 10 to both sides and get 11=x.
So your answer is A

A closed can, in a shape of a circular, is to contain 500cm^3 of liquid when full. The cylinder, radius r cm and height h cm, is
Gemiola [76]
To express the height as a function of the volume and the radius, we are going to use the volume formula for a cylinder: V= \pi r^2h
where
V is the volume 
r is the radius 
h is the height 

We know for our problem that the cylindrical can is to contain 500cm^3 when full, so the volume of our cylinder is 500cm^3. In other words: V=500cm^3. We also know that the radius is r cm and height is h cm, so r=rcm and h=hcm. Lets replace the values in our formula:
V= \pi r^2h
500cm^3= \pi (rcm^2)(hcm)
500cm^3=h \pi r^2cm^3
h= \frac{500cm^3}{ \pi r^2cm^3}
h= \frac{500}{ \pi r^2}

Next, we are going to use the formula for the area of a cylinder: A=2 \pi rh+2 \pi r^2
where
A is the area 
r is the radius 
h is the height

We know from our previous calculation that h= \frac{500}{ \pi r^2}, so lets replace that value in our area formula:
A=2 \pi rh+2 \pi r^2
A=2 \pi r(\frac{500}{ \pi r^2})+2 \pi r^2
A= \frac{1000}{r} +2 \pi r^2
By the commutative property of addition, we can conclude that:
A=2 \pi r^2+\frac{1000}{r}
