Answer - 3

B = 36/ (12-9*5)
B = 36/ (12- 45)
B = 36/ (-33)
E = N/A
D = 3
M = N/A
A = N/A
S = N/A

Answer:

12/11

Step-by-step explanation:

Any work inside parentheses must be done first.

Thus, start with (3 + 6); this equals 9. Then the original expression becomes

36÷{12-(9)*5}

Multiplication and division are done before addition and subtraction. Thus, the next stp is to multiply 9 and 5, obtaining 45, inside the parentheses. This results in

36÷{12-45}, or 36÷{33}, which leads to the answer 36/33, or 12/11.

Recall Euler's theorem: if $\gcd(a,n) = 1$ , then

$a^{\phi(n)} \equiv 1 \pmod n$

where $\phi$ is Euler's totient function.

We have $\gcd(9,32) = 1$ - in fact, $\gcd(9,32^k)=1$ for any $k\in\Bbb N$ since $9=3^2$ and $32=2^5$ share no common divisors - as well as $\phi(9) = 6$ .

Now,

$37^{32} = (1 + 36)^{32} \\\\ ~~~~~~~~ = 1 + 36c_1 + 36^2c_2 + 36^3c_3+\cdots+36^{32}c_{32} \\\\ ~~~~~~~~ = 1 + 6 \left(6c_1 + 6^3c_2 + 6^5c_3 + \cdots + 6^{63}c_{32}\right) \\\\ \implies 32^{37^{32}} = 32^{1 + 6(\cdots)} = 32\cdot\left(32^{(\cdots)}\right)^6$

where the $c_i$ are positive integer coefficients from the binomial expansion. By Euler's theorem,

$\left(32^{(\cdots)\right)^6 \equiv 1 \pmod9$

so that

$32^{37^{32}} \equiv 32\cdot1 \equiv \boxed{5} \pmod9$

Dominic is designing a new board game, and is trying to figure out all the possible outcomes. How many different possible outcom

oksian1 [2.3K]

Answer:

If he spins a spinner with 5 equal sections they have equally likely probability of 20%

If he rolls a fair die in the shape of pyramid with 4 sides each side has probability of 25%

If he rolls a fair die in the shape of cube with 6 sides each side has probability of 16.7

Total number of outcomes = 5 * 6 * 4 = 120

Question 4 (Fill-In-The-Blank Worth 6 points)

Marrrta [24]

The formula for density of an object is Density= $\frac{mass}{volume}$ First you plug in the information you already know. 163.5= $\frac{mass}{0.492}$ Now you have to solve for the mass so you multiply 0.492 by 163.5 $0.492*163.5=80.442$ Lastly, you simplify and you will get 80.44. Hope this helped :)
