Twisters, #6 Mathematics

1. Solve for x in 516a751752c0021dc1ef90f0a22c84c3ecb9f1e0.png

2. A circle is inscribed in a equilateral triangle, touching all 3 sides. Then another equilateral triangle is inscribed in the aforementioned circle. What is the ratio of the large triangle to the small triangle?

3. 3%20+%20%5Cfrac%7B3%7D%7B4%7D%5E%7B-1%7D+%20%5Cfrac%7B4%7D%7B5%7D%5E%7B-2%7D+%5Cfrac%7B5%7D%7B6%7D%5E%7B-3%7D....%20%3Dx.

4. bn8pll if x^2017 = 2019, find the value of this expression.

5. x + 10 / x+2 = (x-3/2x+5)^2, find x.

6. cos(1) + cos(2) + cos(3) + cos(4) + cos(5) + cos(6) ..... up to cos(90) - (sin(1) + sin(2) + sin(3)..... up to sin(90)) = x. Find x.

Hi;


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: Twisters, #6 Mathematics

How many positive integers less than 500 are the product of exactly two distinct (meaning different) primes, each of which is greater than 10? should be no 7.
