Aadya is building towers by stacking identically shaped cubes of different colors on top of each other. She has $1$ red cube, $2

$ yellow cubes, $3$ green cubes, and $4$ blue cubes. How many different $10$-cube-high towers can Aadya build using these $10$ cubes so that neither of the bottom two cubes of the tower are green?

Using the Fundamental Counting Theorem, it is found that Aadya can build 1,693,440 cube towers.

<h3>What is the Fundamental Counting Theorem?</h3>

It is a theorem that states that if there are n things, each with n_1, n_2, \cdots, n_n ways to be done, each thing independent of the other, the number of ways they can be done is:

N = n_1 \times n_2 \times \cdots \times n_n

Considering that she has 10 cubes, and the bottom and top cubes cannot be green, the parameters are given by:

n_1 = 7, n_10 = 6, n_2 = 8, n_3 = 7, \cdots n_9 = 1

Hence the number of cubes is given by:

N = 7 x 6 x 8! = 1,693,440.

Aadya can build 1,693,440 cube towers.

Which is true about the completely simplified difference of the polynomials 6x6 − x3y4 − 5xy5 and 4x5y + 2x3y4 + 5xy5?
Galina-37 [17]
<span>Let be A= 6x6 − x3y4 − 5xy5 and B= 4x5y + 2x3y4 + 5xy5 and when we do their difference, it is A - B = 6x6 − x3y4 − 5xy5 -( 4x5y + 2x3y4 + 5xy5)=6x6 − x3y4 − 5xy5 - 4x5y - 2x3y4 - 5xy5 = 6x6 - x3y4 - 2x3y4 - 5xy5 -4xy5 -5xy5=6x6 - 3x3y4 -14xy5, so the final solution is A - B =6x6 - 3x3y4 -14xy5, the degree of this is equal to the degree of - 3x3y4, and it is 3+4=7, the answer is The difference has 3 terms and a degree of 7.</span>

Find the degree measure of each angle in the triangle
Karo-lina-s [1.5K]

Answer:

∠L = 43°

∠M = 121°

∠N = 16°

Step-by-step explanation:

<u>Start by setting all sides equal to 180</u>

3x - 5 + 7x + 9 + x = 180

<u>Add like terms</u>

11x + 4 = 180

<u>Solve for x</u>

11x + 4 = 180

      - 4     - 4

      11x = 176

     / 11     /11

        x = 16

<u>Now, plug in 16 for all instances of x on the triangle and solve.</u>

∠L = 43°

∠M = 121°

∠N = 16°
