How is a chemical change different from a physical change?

Answers

Answer:

Step-by-step explanation:Physical changes only affect the physical properties, such as color, texture, and shape, of a substance. When a substance is changed physically, its chemical properties remain the same. On the other hand, a chemical change alters the chemical properties of a substance.During a physical change the elements and compounds stay as they are.While Chemical changes make new substances.

In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed. The distinction between physical and chemical change is not clear cut

Find the area of the figure at the right. Justify your
procedure.(brainliest included for correct answer)​

Answers

Answer:

9 inches

Step-by-step explanation:

the top 6.1 inches - the bottom 3.1 inches where it cuts off so its 3x3

First, find the lengths of the missing sides. 6.1 - 3.1 = 3, and 6.9 - 3 = 3.9. Now split the figure (I will be splitting vertically, or where the line is). Now solve for the square. length * width = Area, so 3 * 3 = 9. Now solve for the rectangle. Again, length * width =Area so, 3.1 * 6.9 = 21.39. Now add both of the areas together. 21.39 + 9 = 30.39. Therefore, the area of the figure is
30.39 in. sq

2(2x - 8) > 4(3x - 12) Solve the inequality (Just like my previous problem) Make sure to show work!!

Answers

2(2x-8)
2•2x=4x
2•-8= -16
So now 4x-16
Now divide both sides by 4
4x/4=x
-16/4=-4
X=-4

Answer:

x < 8

Step-by-step explanation:

This is a special case, so at the end of the equation we'll flip the sign.

Distribute:

2 * 2x = 4x

2 * -8 = -16

4x - 16

4 * 3x = 12x

4 * -12 = -48

12x - 48

4x - 16 > 12x - 48.

Subtract 12 from both sides.

12 - 12 = 0

4x - 12x = -8x

-8x - 16 > -48

The additive inverse of subtraction is addition so do -16 + -48, which equals -64

-8x/-8 = x

-64/-8 = 8

Now this is where we flip our sign so here we go :)

x < 8

There.

Answer:

18.57

Step-by-step explanation:

First you have to simplify the equation using cross-multiplication

You should get 7v=130

Then divide both sides by 7

You should get v=130/7

simplify that and get 18 4/7

Turn that into decimal form and you get 18.57

Answer:

18.57

Step-by-step explanation:

1. Multiply all terms by the same value to eliminate fraction denominators

v/10 = 13/7

10 x v/10 = 10 x 13/7

2. Simplify

130/7 = 18.571428571429
