dimensions definition

Answers

Marie has a small copy of Rene margrittes famous painting. The Schoolmasters. Her copy has dimensions of 2 inches by 1.5 inches. The scale of her copy is 1 inch:40 cm What is the dimensions of the original painting?


Every 1 inch on her copy is the same as 40 cm on the original. 
You just have to multiply by 40 and convert to centimetres.

2 x 40 = 80
1.5 x 40 = 60

So the original painting is:
80cm by 60cm

Final answer:

Dimensions in physics are the measurable extents that define an object or quantity, such as length for one-dimensional measures and volume for three-dimensional space. Length is typically measured in meters, while volume is a product of lengths and measured in cubic meters. Dimensional analysis is used for unit conversion and to ensure equations are dimensionally consistent.

Explanation:

The term dimensions in the context of physics refers to the measurable extents of any object or physical quantity, which are necessary for defining that quantity. Length is a one-dimensional measure, representing the extent of an object along its greatest dimension, typically measured in meters or its derived units such as kilometers (km) or micrometers (μm). On the other hand, volume is a three-dimensional measure of the space occupied by a sample of matter, represented as the product of lengths in each dimension and has the dimension L3. Dimensional analysis is a method in physics for converting between units using conversion factors to ensure that equations and calculations are dimensionally consistent. Physical quantities must align in dimension in any mathematically correct equation, otherwise known as having dimensional consistency, meaning each term within an equation must have the same dimensional expression.

No. as long as you factor out until you get to numbers that can't be factored you're fine. For example if you're factoring out 36 you can start with 18 and 2 or 12 and 3 or 4 and 9 and still end up with the factorization of 2•2•3•3

Solve the equation:
X+7/8=4



A. X= 4 7/8

B.X= 3 1/8


C.X= - 3 1/8


D. X= - 4 7/8

Answers

answer B.X= 3 1/8

X+7/8=4
x = 4 - 7/8
x =3 8/8 - 7/8
x = 3 1/8
x+7/8 = 4

We want to get the X by itself. So subtract 7/8 from both sides. 

x + 7/8 - 7/8 = 4 - 7/8

Now do the math!

x = 4 - 7/8

A pitcher contains 2/3 quart of water. If an equal amount of water is poured into 6 glasses how much water will each glass contain?

Answers

2/3 x 6 
4 quarts
basically 2/3 x 6/1 
6x2 which is 12
3x1 which is 3
12/3 is 4
4 quarts

Answer:

1/ 9 quart of water or 0.11 quart

Step-by-step explanation:

A pitcher contains= [tex]\frac{2}{3}[/tex] quarts of water

An equal amount of water is to be poured into 6 glasses

We have to find the amount of water in each glass

Hence, amount of water in each glass = [tex]\frac{amount of water }{number of glasses}[/tex]

Hence, amount of water in each glass = [tex]\frac{[tex]\frac{2}{3}[/tex] }{6}[/tex]

Amount of water in each glass = [tex]\frac{2 }{18}[/tex]

Amount of water in each glass = [tex]\frac{1 }{9}[/tex]

Hence, amount of water in each glass = 0.111 quart

Jack and jill painted one-half of Their bedroom in three-fourths of an hour. At this rate, how long would it take them the paint the entire room

Answers

Well they painted HALF the room in 3/4 of an hour.

That means that, considering they keep up the same speed, it will take them 3/4 of an hour to do the OTHER half.

This means that it will take them....

1 and 1/2 hours to do their entire room.


So if they painted 1/2 of the room in 3/4 of an hour ( 45 minutes ) then it would take them another 45 minutes to paint the other half of the room. So 45+45= 90. So 90 minutes, or an hour and a half. Hope this helped! :)

Jill collects stamps. her stamp book has space for 64 stamps she needs 18 more stamps to fill the book how many stamps does Jill have now

Answers

You need to subtract, but Jill has 46 stamps

Final answer:

Using subtraction, we determined that Jill currently has 46 stamps in her stamp book by subtracting the 18 stamps she needs to fill it from the total stamp book capacity of 64.

Explanation:

Jill's stamp collection problem is a simple subtraction problem in mathematics. To find out how many stamps Jill currently has, we subtract the number of stamps she needs to fill the book from the total capacity of the stamp book. If the stamp book has space for 64 stamps and she needs 18 more stamps to fill the book, we can calculate the number of stamps she currently has by doing the following calculation:

Total stamps space - Stamps needed = Stamps Jill has

64 - 18 = 46 stamps

Therefore, Jill currently has 46 stamps.

is 3x-5+y=2y-4 linear if so write the equation in standard form and give the values of A B and C

Answers

Equation in standard form:
Ax+By=C

We have:
3x-5+y=2y-4
3x+y-2y=-4+5
3x-y=1

Therefore:
A=3
B=-1
C=1

Answer: the equation in standard form would be: 3x-y=1; and the values of A, B and C would be: A=3; B=-1 and C=1.

Final answer:

The given equation is linear and can be written in standard form as 3x - y = 1, where the coefficients are A = 3, B = -1, and C = 1.

Explanation:

The equation 3x - 5 + y = 2y - 4 is indeed linear. To write it in standard form, we combine like terms and move all terms involving variables to one side of the equation and the constant terms to the other side. Subtracting y from both sides and adding 5 we get 3x - y = 1. Here, A is 3, B is -1, and C is 1.
