Answer:
x-13
Step-by-step explanation:
why you may ask?
subtracted=being taken away from
13 is *being taken away from* x
so if using numbers, 13 is being taken away from 20
or 13 is being subtracted from 20 would be 7, so x-13 would be your expression

Answer:
61.8m^2are
Step-by-step explanation:
3 times 9 = 27
you multiply that two more times because there are 3 of them. So now we have 54 m.
Now we find the area of the triangles
area = 1/2 base times height
1/2(2.6) * 3
1 * 2.6 * 3/2
2.6 * 3/2
7.8/2
3.9
3.9 times 2 because there two triangles
7.8 + 54 = 61.8 m^2
i dont know what to do for number 6, please someone help/explain!
Answer:
r= 16.65
Step-by-step explanation:
Formula of cone V= 1/3 pi r ^2 h
They give us the volume and height, we just need to find the radius.
85= 1/3 pi r^2 9
1/3 of 9 is 3.
85= 3 pi r^2
divide by 3 on both sides.
28.3= pi r^2
square both sides with calculator or logic and round to nearest tenth.
5.3= pi r
divide pi.
r= 5.3 pi = 16.65
To find volume, plug everything in the formula.

2. ║x-(-12)║, if x > -12
3. ║x-(-12)║, if x < -12

6. ║x ÷ 3║, if x < 0
7. ║x ÷ 3║, if x = 0
**WILL GIVE BRAINLIEST IF 4 OR MORE ARE CORRECT**
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!

How do you think you could represent the number 2,300 as a number times a multiple of 10? How do you think you could represent the number 2,300 as a number times 10 to some exponent? How would you describe the relationship between the two representations?
Answer:
In common scientific notation, any nonzero quantity can be expressed in two parts: sufficient whose absolute value is greater than or equal to 1 but less than 10, and a power of 10 by which the coefficient is multiplied. In some writings, the coefficients are closer to zero by one order of magnitude. In this scheme, any nonzero quantity is expressed in two parts: a coefficient whose absolute value is greater than or equal to 0.1 but less than 1, and a power of 10 by which the coefficient is multiplied. The quantity zero is denoted as 0 unless precision is demanded, in which case the requisite number of significant digits are written out

Demarcus has a cereal box shaped like a rectangular prism. It measures 758 inches long, 212 inches wide, and 12 inches high. What is the volume of the cereal box?
Answer:
1,928,352 in cubed
Step-by-step explanation:
The volume of the cereal box is [tex]\rm 228\dfrac{3}{4}[/tex]cubic inches.
What is the volume of rectangular prism?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.

How do you convert mass to volume without density?
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.
