9√2 is squared first.

so its 162.

now according to Pythagoras theorem,

x2+x2=162

2x^2= 162

x^2= 162÷2

x^2= 81

x= √81

x=9

in a right angled triangle, (height)^2 + (base)^2 = (hypotenuse)^2

here we have , height as X and base as X too , so; x^2 + x^2 = (9√2)^2

2(X)^2 = 162

x^2 = 162/2

X^2 = 81

X = √81 = 9

Answer:

Jordan had 18 coins. Two-thirds of the coins were dimes. How many coins were dimes?

Min had 18 quarters. He used 2/3 of the quarters to play arcade games. How many quarters did Min use?

Step-by-step explanation:

2/3 × 18

Checking all options

Sarah mixed 18 ounces of orange juice with 23 ounce of pineapple juice. How many ounces of juice did she have in all?

Ounces of orange juice = 18

Ounces of pineapple juice = 23

Total ounces of juice = 18 + 23

= 41 ounces

A container held 18 ounces of water. Two-thirds of the water leaked out of the container. How many ounces of water were left in the container?

Total water in the container = 18

Water leaked out = 2/3

Ounces of water left = 18 - 2/3(18)

= 18 - 36/3

= 18 - 12

= 6

Jordan had 18 coins. Two-thirds of the coins were dimes. How many coins were dimes?

Total Number of coins = 18

Dimes = 2/3 of 18

Number of dimes = 2/3 × 18

= 36 / 3

= 12

Min had 18 quarters. He used 2/3 of the quarters to play arcade games. How many quarters did Min use?

Total quarters = 18

Quarters used for game = 2/3 × 18

= 2/3 × 18

= 36 / 3

= 12

Answer:

infinite number of solutions

Step-by-step explanation:

Given

- 4n + 9 = - 2(2n - 1) + 7 ← distribute and simplify right side

- 4n + 9 = - 4n + 2 + 7

- 4n + 9 = - 4n + 9

Since both sides are equal then any value of n makes the equation true.

That is there are an infinite number of solutions

Answer:

ut you can consider it to be 25 41

The two ways I would do this is subtract 27% OR multiply by 73 percent.

Answer:

6

Step-by-step explanation:

if you divide 18 by 4 you get 4.5, and if you divide 27 by 4.5 then you get six. hope this is right :/

Answer: 6 books

Work: Okay, The first thing I did was find out how much one book costs. To find that out, I divided $18/4, and the answer is $4.50 per book. Now, we add $4.50 until it's $27. I did that, and it was just 2 more books. (4.50 + 4.50 is $9, so add nine dollars to $18, and that would be $27. Then, divide 27/4.5, and you get 6, meaning the 6 books)

Sorry if this was confusing, but I hope I helped you. :)

Answer:

Rectangles! Nice.

Step-by-step explanation:

This is a very simple problem. Let's first represent the width of the rectangle as the variable x.

Then, we know that the length of the triangle is x+2. See where I'm going with this?

The formula for the perimeter of an rectangle is [tex]P=2*Length+2*Width[/tex].

All we have to do next is just input our values for the length and width, and you'll be golden!

[tex]56=2(x+2)+2(x)\\56=4x+4[/tex]

Next to subtract 4 from both sides and then to divide by 4!

[tex]52=4x\\x=13[/tex]

There's your answer! Don't know why Brainly is bugged right now.

NOTE: If you can't read the answer above, the width is 13cm. This also means that the length is 15cm.

Hope this helps!

Stay safe!

A proportional relationship is of the form

y = kx

This is equation is of the form

y = kx+b

They are not the same so it is not a proportional relationship

Answer:

Aman's age = 20, Arun's age = 28

Step-by-step explanation:

Let [tex]x[/tex] = Aman's age

Let [tex]y[/tex] = Arun's age

- - - -

[tex]x+4+y+4=56[/tex] (Sum of their age is 56 after 4 years in the future)

[tex]x+y+8=56[/tex]

[tex]x+y=48[/tex]

[tex]\frac{x}{y} = \frac{5}{7}[/tex] (Ages are in the ratio 5:7)

[tex]x=\frac{5}{7}y[/tex]

Now, we can use substitution to find for Arun's age:

[tex]x+y=48[/tex]

[tex]\frac{5}{7}y+y=48[/tex]

[tex]\frac{12}{7}y=48[/tex]

[tex]y=28[/tex]

∴ Arun is [tex]28[/tex]

To find for Aman's age, we can use substitution:

[tex]x+y=48[/tex]

[tex]x+28=48[/tex]

[tex]x=20[/tex]

∴ Aman is 20

Hope this helps :)
