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

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:

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. :)

no

Step-by-step explanation:

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:

10.5

Step-by-step explanation:

You can use ratios to solve this problem.

The original dimensions of the photo is

5 in. by 7 in.

This can be written as:

5:7

And the next is 7.5:?

Then you can use ratios to solve this.

5:7=

7.5:?

5*1.5=7.5 so you can multiply the other side by the same thing. 7*1.5=10.5

The width is 10.5 inches.

Answer:

x³ - 3 x² - 13 x + 15 = 0

Step-by-step explanation:

Basically you can create three factors like this:

(x+3)(x-1)(x-5)=0

That will each represent one zero.

Work it out and you get x³ - 3 x² - 13 x + 15 = 0

Answer: z = -2

Step-by-step explanation:

6z + 10 = -2

add 10 on both sides

6z = -2 -10

6z = - 12

divide 6 on both sides

z = -2

Answer:

z= -2

Step-by-step explanation:

6z+10=-2

-10. -10

6z = -12

÷6. ÷6

z= -2

Answer:

The average rate of change of the function for the interval [-4, 0] is  [tex]\frac{3}{4}[/tex] ⇒ A

Step-by-step explanation:

The average rate of change of the function is the slope of the line that represents the function, m = Δy/Δx, where

From the given figure

→ The values of x in the interval [-4, 0] are -4 and 0

∵ The point (-4, 0) and (0, 3) lie on the line

∴ x1 = -4 and x2 = 0

∴ x2 = 0 and y2 = 3

∵ Δx = 0 - (-4) = 0 + 4 = 4

∵ Δy = 3 - 0 = 3

→ By using the rule of the slope above

∴ m = [tex]\frac{3}{4}[/tex]

∵ The average rate of change of the function = the slope of the line

∴ The average rate of change of the function for the interval [-4, 0] is  [tex]\frac{3}{4}[/tex]
