V = 4/3 pi r^3

r is directly proportional to the diameter

and v is proportional to r^3

so

v is proportional to d^3

for d tripled

v is (3)^3 = 27 times original

Determine if the following triangle is a right triangle or not using the Pythagorean Theorem Converse. Triangle with side length

seraphim [82]

Answer:

A right triangle is a triangle in which one of the angles is a 90∘ angle. The "square" at the vertex of the angle indicates that it is 90 degrees. A triangle can be determined to be a right triangle if the side lengths are known.

This is the example my teacher used. However, I still don't understand what makes the integers even or odd. I was hoping someone

Answer:

<h2>Here's what makes an integer odd:</h2>

It is NOT a multiple of 2.

When divided by 2, the quotient would be a decimal or have a remainder or fraction.

<h2>Here's what makes an integer even:</h2>

It is a multiple of 2.

When divided by 2, the quotient has a whole number.

<em>The odd numbers from one to 10 are: 1, 3, 5, 7, 9.</em>

<em>The even numbers from one to 10 are: 2, 4, 6, 8, 10. </em>

With big numbers, if it ends with any of the odd numbers from one to ten, listed above, it would be odd. This goes for the same with even.

<h2>With the x + 2, x + 4, etc:</h2>

An odd number and even number has a pattern....

[odd, even, odd, even, odd...] [1, 2, 3, 4, 5]

So, if x was an odd number, adding it by 2, 4, 6, etc. will result in another odd number.

Here's an example:

$x= 17\\x + 2 = ?\\(17) + 2 = 19$

<em>See how x is an odd number and the sum of the number and two makes another odd number? </em>

The same can go with an even number:

$x=2\\x + 6 = ?\\(2) + 6= 8$

<em>See how x is an even number and the sum of the number and six makes another even number? </em>

I hope my answer helps you understand even and odd numbers.

40 + x + 25= 180

sveta [45]

$\qquad\qquad\huge\underline{{\sf Answer}}♨$

Let's solve ~

$\qquad \sf \dashrightarrow \:40 + x + 25 = 180$

$\qquad \sf \dashrightarrow \:x + 65 = 180$

$\qquad \sf \dashrightarrow \:x = 180 - 65$

$\qquad \sf \dashrightarrow \:x = 115$

I hope you understood the procedure, please let me know if you have any doubts
