Answer:

24 bricks

Step-by-step explanation:

The equation of the bricks per row can be:

b = 60 - 3r

where r = row and b = bricks.

if r = 12:

b = 60 - 3 * 12\\b = 60 - 36\\b = 24

Use strong mathematical induction to prove the existence part of the unique factorization of integers theorem (Theorem 4.4.5). I
valentina_108 [34]

Answer:

Lets say that P(n) is true if n is a prime or a product of prime numbers. We want to show that P(n) is true for all n > 1.

The base case is n=2. P(2) is true because 2 is prime.

Now lets use the inductive hypothesis. Lets take a number n > 2, and we will assume that P(k) is true for any integer k such that 1 < k < n. We want to show that P(n) is true. We may assume that n is not prime, otherwise, P(n) would be trivially true. Since n is not prime, there exist positive integers a,b greater than 1 such that a*b = n. Note that 1 < a < n and 1 < b < n, thus P(a) and P(b) are true. Therefore there exists primes p1, ...., pj and pj+1, ..., pl such that

p1*p2*...*pj = a

pj+1*pj+2*...*pl = b

As a result

n = a*b = (p1*......*pj)*(pj+1*....*pl) = p1*....*pj*....pl

Since we could write n as a product of primes, then P(n) is also true. For strong induction, we conclude than P(n) is true for all integers greater than 1.

$30 board game on sale for $20.10

Ok so to solve for percent off
percent off means discount


so therefor we need to find how much was discounted
30-20.10=9.90

so we see that 9.90 was discounted
to find the percent we do
discount/total=percent discount
9.90/30=0.33

percent means parts out of 100
0.33/1 times 100/100=33/100=33%

answer is 33% discout

Can someone double check my work for this problem? I got 38°??

We need to use Law of sine.

sin A/a = sin C/c
sin A/|CB| = sin C/|AB|

sin A/14 = sin(118⁰)/ 20
sin A = (14*sin(118⁰))/ 20

A=arcsin((14*sin(118⁰))/ 20) ≈ 38⁰
