does 9/20 and 18/30 form a proportion

Answers

Answer 1

Answer:

No, they don't.

Step-by-step explanation:

I'm going to divide 18 by 9 and 30 by 20. If the quotients are the same, then we do have a proportion.

18 ÷ 9 = 2

30 ÷ 20 = 1.5

The quotients aren't the same. Same thing if you convert the fractions to decimals:

9 ÷ 20 = 0.45

18 ÷ 30 = 0.6

This means the two values do NOT form a proportion.

Hope this helps! Have a great day!

Answer 2

Answer:

No.

Step-by-step explanation:

9/20=18/30

9*30=20*18

120=360

If you would like to know how this works please do not hesitate to ask.

A group of 15 people each bought both a book that cost x dollars and a bookmark that cost $1. A group of 3 people each bought both a book that cost x dollars and a backpack that cost $36. Both groups spent the same amount of money. What is the price of the book?

Answers

Answer:

$1.40

Step-by-step explanation:

Answer:

The price of the book is $7.75.

Step-by-step explanation:

Let's first establish an equation.

If I buy a book costing [tex]x[/tex] dollars and a bookmark costing 1 dollars, I will have spent [tex]x + 1[/tex] dollars. So a group of 15 people doing the same will have spent [tex]15(x+1) = 15x + 15[/tex] dollars.

Analogously, the group of 3 people has spent [tex]3(x+36) = 3x + 108[/tex] dollars.

Since we know that both groups spent the same amount of money, we can set the two expressions equal to each other:

[tex]15x+15=3x+108\\12x=93\\x=7.75[/tex]

Because [tex]x[/tex] was the price of the book, which was asked for in the question, we conclude that the answer is $7.75.

yeah, i need help solving this and i need help quick please.

Angle e and c are the same because they are opposite interior angles. Therefore you can set it up in an equation like: 117=5P+27 and solve.
117=5P+27 you need to subtract 27 from both sides
90=5P you need to divide both sides by 5 to get
P=18

A 15 meter trunk broke and fell against a wall. The base of the tree is 10 meters from the wall. Found the distance from the ground to the top of the tree. Round your answer to the nearest tenth. Identify which trig function you will be using to solve the problem.​

Answers

Answer:

11.2 m

Step-by-step explanation:

The distance from the ground to the top of the tree = h

Using Pythagoras rule :

Adjacent² = hypotenus² - opposite²

h² = 15² - 10²

h² = 225 - 100

h² = 125

h = Sqrt(125)

h = 11.18

h = 11.2 m to the nearest tenth

Answer:

40⁰

Step-by-step explanation:

Main principles:

1.Alternate angles equal

2.Vertically opposite angles are equal

If angle 2 is 40⁰, then using the second principle,angle 3 is also 40⁰

Then, using the first principle,(alternate angles/angles that form any variation of "z"), angle 6 is also 40⁰.

There are other ways to do this like using co-interior angles, straight angles and other methods, these are the easiest to understand
