Answer:

-(x-120)

x-(-12)

-(x-(-12))

0

x / 3

-(x/3)

0

Step-by-step explanation:

1. || x-120||, if x<-120.

If x is less than -120, then x - 120 will be a negative number.

Since absolute value will make a negative number positive, the answer will be  -(x-120).

2. ||x-(-12)||, if x > -12.

Basically x -(-12) = x + 12. If x is greater than -12, then ||x+12|| will be positive. The answer is x-(-12).

3. ||x-(-12)||, if x < -12.

Again, x-(-12) = x + 12. If x is less than -12, ||x+12|| will be negative.

Absolute value makes a negative number positive. The answer is -(x-(-12)).

4. ||x-(-12)||, if x = -12.

So we can substitute x with -12. ||-12-(-12)|| = ||-12+12||, which equals ||0||, which is also just 0. (Answer is 0.)

5. ||x / 3||, if x > 0.

Any positive number divided by another positive number will be positive, meaning you can just take out the absolute value sign. Answer is x /3.

6. ||x / 3||, if x < 0.

Any number less than 0 is negative, and any negative number divided by a positive number will be negative. If we take out the absolute value, we'll have to reverse it with a -. Answer: -(x/3).

7. ||x / 3||, if x = 0.

||0/3|| = ||0||, which is still 0.

Hope this helps!

Answer:

#1-

The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties. The structure of the table shows periodic trends. The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right. The columns, called groups, contain elements with similar chemical behaviours. Six groups have accepted names as well as assigned numbers: for example, group 17 elements are the halogens; and group 18 are the noble gases. Also displayed are four simple rectangular areas or blocks associated with the filling of different atomic orbitals. #2-118

Step-by-step explanation:

The volume of the cereal box is [tex]\rm 228\dfrac{3}{4}[/tex]cubic inches.

The volume of rectangular prism is given by :-

[tex]\rm Volume = Length \times Width \times Height[/tex]

Demarcus has a cereal box shaped like a rectangular prism. It measures 7 5/8 inches long, 2 1/2 inches wide, and 12 inches high.

The volume of the cereal box is determined in the following steps given below.

[tex]\rm Volume = Length \times Width \times Height\\\\\rm Volume = 7\dfrac{5}{8}\times 2\dfrac{1}{2} \times 12\\\\\rm Volume = \dfrac{7\times 8+5}{8} \times \dfrac{2\times 2+1}{2} \times 12\\\\\rm Volume = \dfrac{61}{8} \times \dfrac{5}{2} \times 12\\\\Volume =\dfrac{3660}{16}\\\\Volume=228\dfrac{3}{4}[/tex]

Hence, the volume of the cereal box is [tex]\rm 228\dfrac{3}{4}[/tex]cubic inches.

Answer:

NO, the these three border pieces will not make a right triangle

Step-by-step explanation:

Use the compound amount formula A = P(1 + r)^t:

Here A = ($27,000)(1 + 0.0415)^5

         A = ($27,000)(1.0415)^5 = $33,087.21

Subtracting the principal amount, $27,000, leaves the compound interest amount:  $33,087.21 - $27,000 = $6087.21

She will pay $6,087.21 interest on this loan.

Answer:  A

Step-by-step explanation:

The question asks about how much space the cylinder can hold. That's how i know they are really asking for the volume of the cylinder.

Next, the volume of a cylinder is V= πr²h

R is the radius

h is the height

π= 3.14 (in this question).

We know that the diameter is 30, and that the radius is always 1/2 of the diameter. To find the radius, find 1/2 of 30. Whenever you see something of something, just turn the "of" into the multiplication sign. So just do 1/2 x 30= 15.

R= 15

H= 4.5

Pi= 3.14

Now we can plug into the formula:

Using pemdas, do exponents first. Then multiply from left to right.

V= πr²h

V= 3.14x15²x4.5

V= 3.14x225x4.5

V= 706.5x4.5

V= 3,179.25

3,179.25  rounds rounds to just 3,179 because first you round the .25 to point 3, and because 3 is under 5, it rounds down. The answer is A

Answer:

Well, you could always just put it onto a scale to find the mass. But assuming you aren't talking about a laboratory setting. sorry if its all werid i cant really put it into how it supposed to be

The general formula is:

ρ

=

m

V

where

ρ

is density in

g/mL

if mass

m

is in

g

and volume

V

is in

mL

.

So to get the mass...

m

=

ρ

V

Or to get the volume...

V

=

m

ρ

When you have the volume and not the density, and you want to find mass, you will need to find the density yourself. It's often readily available on the internet.

Just replace "[...]" with the object you want, and if it's not exactly what you need, consider it an estimate.

These days, you should be able to search for the density of any common object.

When you have the density and volume but not the mass, then just make up a mass.

You shouldn't need specific numbers to do a problem. You can always solve a problem in general and get a solution formula. If you need to, just make up some numbers that you know how to use.
