Answer:

To determine whether a decimal is rational or not, you need to know that...

Irrational numbers don't end and have no pattern whereas rational numbers are the complete opposite. Rational numbers end and have a repeating pattern.

Step-by-step explanation:

Here are examples of irrational numbers:

0.9384903204..... , π , √2

Examples of rational numbers:

0.777777... (is rational because it has a repeating pattern of 7) , √49

Hope this helps :)

Can you help me with this math problem and tell me how to do it?

Let the number of songs Lou has = X

Kelly has 4 times as many as Lou, which would be written as 4X

Tiffany has 6 times as many songs as Lou, which would be written as 6X


The total number of songs = 682


You need to add all three people together to equal 682


So you would get:

X + 4X + 6X = 682 songs.

Combine all like terms ( 6x + 4x + X = 11x)

11x = 682


Now to solve for X divide both sides by 11:

x = 682 / 11 = 62


Lou = x = 62 songs.

Kelly = 4x = 4(62) = 4*62 = 248 songs.

Tiffany = 6x = 6(62) = 6 *62 = 372 songs.

NUMBER 6 PLEASE HELP ASAP
Aleksandr [31]

Answer:

Part A: 115

Part B: 36000

Explanation:

Part A asks for the perimeter, which is adding, so add up the 15, 40, and 60, which will equal to 115.

Part B asks for the area, which is multiplying, so you multiply the numbers,

15 x 40 x 60 = <u>36000</u>

15 x 40 = 600

600 x 60 = 36000

You could try multiplying it a different way but get the same answer:

60 x 40 x 15 = <u>36000</u>

60 x 40 = 2400

2400 x 15 = 36000

I'm not sure if this is correct but I hope I helped

have a great day/night :))

AD = 3x + 4 and CD = x + 6, what is the value of x?
lesantik [10]
Your answer would be x = 1.

The rules for a kite shape is that two pairs are of equal length, which means we can say that AD = CD and thus form an equation:

3x + 4 = x + 6
- x
2x + 4 = 6
- 4
2x = 2
÷ 2
x = 1

I hope this helps!
