Mathematics

Virty [35]3 years ago

Answer:

(2)(3^2)(5^2)

Step-by-step explanation:

we know that

The <u>Least Common Multiple</u> (LCM) of a group of numbers is the smallest number that is a multiple of all the numbers.

we have

15,18 and 25

Decompose the numbers in prime factors

15=(3)(5)

18=(2)(3^2)

25=(5^2)

Multiply common and uncommon numbers with their greatest exponent

so

The LCM is equal to

LCM=(2)(3^2)(5^2)

LCM=450

Which best describes the complement of spinning any number less than 3?
tatuchka [14]

Answer:

  • <u>The complement of spinning any number less than 3, is spinning a number equal to or greater than 3.</u>

Explanation:

The complement of a subset is the subset of elements that are not in the given subset.

You must know which numbers the spinner has.

Assuming the spinner has the numbers 1, 2, 3, 4, the complement of spinning any number less than 3, is spinning a number that is not less than 3.

Then, that is spinning a number that is equal to or greater than 3.

The numbers that are equal to  or greater than four, for a spinner that has the numbers 1, 2, 3, and 4 are 3 and 4.

Thus, the complement of spinning any number less than 3 is spinning a three or a four.

<h2>d ≈ 19.1 cm</h2>

<em>Using the formulas</em>

<em>C = 2πr</em>

<em>d = 2r</em>

<em>Solving for 'd' (diameter)</em>

<em>d = C</em>

<em>π = 60</em>

<em>π ≈ 19.09859cm</em>

How many times do 2 goes into 19
ser-zykov [4K]
Nine and a half times.
***
you can put it fully nine times. You reach 18 like this. But you have 1 more to go until 19! So, just cut the 2 in half to get 1, and put that in!
