You have two pieces for fabric. One piece is 6 feet wide and the other piece is 7.5 feet wide. You want to cut both pieces into

My name is Ann [436]

Answer:

Strips should be 1.5 ft wide.

Step-by-step explanation:

Given:

Width of 1st piece = 6 ft

Width of 2nd piece = 7.5 ft

To find:

To find the maximum width possible to make strips of equal size from both the pieces.

Solution:

This problem can be visualized as if we are given two numbers and we have to find the Highest common factor for both of them i.e. HCF of 6 and 7.5 will be our answer.

Let us try to factorize the given factors:

$7.5 = 3 \times 2.5 = \underline {3 \times 0.5} \times 5$

$6 = 3 \times 2 = \underline {3 \times 0.5 }\times 2$

The common factors are highlighted above as underlined.

Therefore, the answer is 3 $\times$ 0.5 = 1.5 ft

Strips should be 1.5 ft wide.

Describe the three base materials in soil in terms of porosity and permeability.

777dan777 [17]

Porosity:

Porosity is an intrinsic property of every material.
It refers to the amount of empty space within a given material.
In a soil or rock the porosity (empty space) exists between the grains of minerals.
The amount of water a material can hold is directly related to the porosity since water will try and fill the empty spaces in a material.
We measure porosity by the percentage of empty space that exists within a particular porous media.

Permeability:

Permeability is another intrinsic property of all materials and is closely related to porosity.
Permeability refers to how connected pore spaces are to one another.
If the material has high permeability than pore spaces are connected to one another allowing water to flow from one to another, however, if there is low permeability then the pore spaces are isolated and water is trapped within them.

Answer:

22.) 2.0651

23.) 4.231

Step-by-step explanation:

22.) Substitute values into equation

(x)(y) + 2 =

(2.1)(0.031) + 2 = 2.0651

23.) Substitute values into equation

(y) + (x)2

(0.031) + (2.1)2 = 4.231

Simplify to create an equivalent expression.

Elis [28]

You would use PEMDAS so that means you would start by multiplying 3 with the parentheses 3(2+6d) on both sides then you would combine like terms so you would add 18d+18d. Then you would subtract 6- -5 on both sides then solve for a one-step equation

3(2+6d)-5=3(2+6d)-5
6+18d-5=6+18d-5
6+36d-5=6-5
1+36d=1
-1. -1
36d/36. 0/30
D=0
