Answer:
20 - 10 cm sections can be cut from a pipe of original length 2 m
Step-by-step explanation:
Convert 2 meters to cm:
2 m 100 cm
------ * ---------------- = 200 cm
1 1 m
Next, divide this 200 cm total length by (10 cm/section) to determine the number of sections:
200 cm
--------------------- = 20 sections
10 cm/section
20 - 10 cm sections can be cut from a pipe of original length 2 m

Answer:
2x^3−7x^2+16x−15
Step-by-step explanation:
(2x−3)(x^2−2x+5)
=(2x+−3)(x^2+−2x+5)
=(2x)(x^2)+(2x)(−2x)+(2x)(5)+(−3)(x^2)+(−3)(−2x)+(−3)(5)
=2x^3−4x^2+10x−3x^2+6x−15
=2x3−7x2+16x−15
Answer:
2x³ -7x² +16x -15
Step-by-step explanation:
You distribute the (2x-3) onto the other trinomial and then combine the like-terms.
(2x-3)(x²-2x+5)
2x³ -4x² + 10x -3x² +6x -15
2x³ -7x² +16x -15

Measurements of atoms, such as amounts, distances, and weights, are often very large or very small when compared to measurements of things you can see or touch. Scientific notation represents numbers as a power of 10. This makes very large or small numbers easier to use and understand. Approximately 7,500,000,000,000 carbon atoms fit across the period that you make with your pencil. Express this number in scientific notation. (PLEASE ANSWER FAST I'LL GIVE BRAINLIEST ALSO PLEASE DO ALL THIS IS WORTH 30 POINTS)
Step 1 Rewrite the number with a decimal after the first nonzero digit.7.500000000000
Step 2 Find the number of places and the direction you moved the decimal. If a number does not show a decimal, the decimal is at the right end of the number.You moved the decimal 12 places to the left.
Step 3 Drop the zeros, and write the number of places you moved the decimal as a power of 10. If you moved the decimal to the right, the power is negative. If you moved the decimal to the left, the power is positive.7.5 × 10 12
Step 4 Reverse the process to change scientific notation back to a whole number. A positive power of 10 moves the decimal to the right. A negative power of 10 moves the decimal to the left.

A sphere has a radius of 5 feet. Find the volume of the sphere. Leave your answer in terms of pie. Then use 3.14 for pie and round the volume to the nearest 10th. Volume in terms of pie=? Volume in using 3.14=?
The solution is, The Volume is 523.6, of the sphere has a radius of 5 feet.
What is volume?In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.
here, we have,
Given,
r = 5 ft
pi = 3.14
Formula
the volume of sphere is:
V = 4/3 * 3.14 * r^3
Solution
V = 4/3 * 3.14 * 5^3
V = 4/3 * 3.14 * 125
V ≈ 523.59878
V ≈ 523.6 m^3
as, we get,
V≈523.59878
and 5 or more raise the score so the 9 makes the 5 into 6 and drop all of the other numbers.
Hence, The solution is, The Volume is 523.6, of the sphere has a radius of 5 feet.

Answer:
Step-by-step explanation:
in the first one 2,4,6,and 8 are equal meaning they all equal to 75. the other angles 1,3,5,and 7 equal 105 because 180 - 75 = 105
for the other ones i'm not sure srry

I need the correct answer for this it says incorrect?????
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

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.
