4 0

Answer:

Options 1 and 4 are arithmetic

Step-by-step explanation:

Arithmetic means that you are adding or subtracting a number in a sequence.

For option 1, we are adding 2 every time.

-3 + 2 = -1   -1 + 2 = 1   1 + 2 = 3

For option 4, we are subtracting 7 every time.

32 - 7 = 25   25 - 7 = 18   18 - 7 = 11

Option 2 is geometric. Geometric means you are multiplying or dividing by a number in a sequence.

2 * 3 = 6   6 * 3 = 18   18 * 3 = 54

Option 3 is actually quadratic. This is similar to a arithmetic, except instead, the amount added to the number is multiplied by 2 every time.

1 + 2 = 3   (2 + 2 = 4)   3 + 4 = 7   (4 + 4 = 8)   7 + 8 = 15

What is the number pie
eduard

Hi there!


In math, we don't call this number "Pie", we call it Pi. The numbers that we recognize as Pi are 3.1415926 and so on. The numbers never stop. The numbers never repeat either.


There is a special symbol for Pi that people recognize quickly, and so you do the same, here is what Pi looks like - π :)


Wanna see something cool? The attached file is how Pi got its name - From its numbers 3.14!


Neat, huh?


Another thing I want to include is Pi Day. This recently passed and it was called Pi Day for being March (The third month of the year) and the fourteenth day. Normally Pi Day falls on a year ending with 15. Last year, in 2015, it was a true Pi Day. In 99 years, it will be Pi Day again!


Hope this helps!

Message me if you need anything else! I'd be happy to help! :D

What is the greatest common factor of the numerator of ?
Annette [7]

The greatest common factor of the numerator and denominator of the rational expression is x - 4

<h3>How to determine the greatest common factor?</h3>

The fraction expression is given as:

\frac{5x-20}{x^2-2x-8}

Factorize the numerator and the denominator

\frac{5x-20}{x^2-2x-8} = \frac{5(x-4)}{(x- 4)(x + 2)}

Cancel out the common factor

\frac{5x-20}{x^2-2x-8} = \frac{5}{(x + 2)}

The common factor that was canceled out is x - 4

Hence, the greatest common factor of the numerator and denominator of the rational expression is x - 4

Given two equilateral triangle; the length of the sides of the 2nd triangle are 2 less than 3
goldfiish [28.3K]

9514 1404 393

Answer:

  first triangle -- side: 304.8 mm; perimeter: 914.4 mm

  second triangle -- side: 863.6 mm; perimeter: 2590.8 mm

Step-by-step explanation:

We are given two equilateral triangles. The perimeter of the second is given as 102 inches, so its sides have length 102/3 = 34 inches. This is 2 less than 3 times the side length in the first triangle. So, adding 2 will give 3 times the side length of the first triangle: 36 inches, which also happens to be its perimeter. Those side lengths are 36/3 = 12 inches.

Now, we know:

  first triangle -- side length 12 inches, perimeter 36 inches

  second triangle -- side length 34 inches, perimeter 102 inches.

These measurements are desired in millimeters. Each inch is 25.4 millimeters, so we can find the desired measures by multiplying these numbers by 25.4.

  12×25.4 = 304.8; 36×25.4 = 914.4

  34×25.4 = 863.6; 102×25.4 = 2590.8

The desired lengths are ...

  first triangle -- side: 304.8 mm; perimeter: 914.4 mm

  second triangle -- side: 863.6 mm; perimeter: 2590.8 mm

romanna [79]

2/3 on video games

1/3 left

1/3 x 1/2 = 10 (half of 1/3 is $10)

= 1/6 of the whole

1/6 x 10 = 60

Therefore, you have $60 at first
