A plumber has a 2-meter length of pipe. He needs to cut it into sections that are 10 centimeters long. How many sections will he be able to cut? (I will give brainliest if you answer first)

Answers

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

Which key correctly represents the information below?

A) 11 | 2 = 12
B) 1 | 2 = 12
C) 11 | 2 = 112
D) 11 | 2 = 13

Answers

Answer:

The correct answer is C) 11 | 2 = 112

Step-by-step explanation:

That is because that is how these kinds of stem and leaf plots work. You add the number on the left to each individual number of the right. For example, the numbers in row 11 are actually:

112, 112, 115, 118.

The reason why we have stem plots is that it removes the need to write the 11 at the beginning of the number and lets you interpret and analyze the data more easily.

Stemplots are also pretty annoying and useless, and something you'll basically never use, so don't worry if they don't make much sense :)

C) 11 | 2= 112 the answer

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

Answers

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

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=?

Answers

The Volume is 523.6
Solution: V=4
3πr3=4
3·π·53≈523.59878 and 5 or more raise the score so the 9 makes the 5 into 6 and drop all of the other numbers

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.

y-y1 = m(x-x1) where y1 and x1 indicate the coordinates of the point and m indicates the slope

y-(-1) = -1/3(x-(-3)

y+1 = -1/3x-1

y = -1/3x -2

You and your friends went to UNO's for dinner (way back in 2019). Together the total bill for your meals was $40. You have a 15%-off coupon for the meal! Then, after the discount, a 7% sales tax is applied. What is the final price, after the discount and the tax, that you are your friends have to pay for the meal?

Answers

Answer:

$36.38

Step by step explanation:

First, we need to find out what 1% of $40 dollars is. To do this, we divide 40 by 100.

This gives us $0.40.

To then find out fifteen percent of $40, you then times $0.40 by 15.

This gives us 6 dollars.

Now, to work out the discount, we take 6 from 40.

$40 - $6 = $34

Now we have to work out the tax.

Again, we have to work out what 1% of $34 is.

This gives us $0.34

Then times that by 7 to find 7%

0.34 x 7 = $2.38

Since this is tax we have to add instead of subtracting.

$34 + $2.38 = $36.38 as the final bill.

The answer to your question is $36.38

How do you convert mass to volume without density?

Answers

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.
