We have to basically multiply:

\sf{\frac{11}{17}\times 475}

And simplifying that we get

\sf{307.35}

And since there can't be .35 person

So out final answer is \boxed{\sf{307 people}}

Ksju [112]

Answer:

16.07 milligrams

Step-by-step explanation:

From the question,

Using the formula of radioactive decay,

R/R' = 2ᵃ/ᵇ..................... Equation 1

Where R = Original mass of the polonium-210, R' = Final mass of polonium-210 after decaying, a = Total disintegration time, b = half life of polonium-210.

Make R' the subject of the equation

R' = R/(2ᵃ/ᵇ)................ Equation 2

Given: R = 100 milligrams, a = 1 years = 365 days, b = 138.39 days

Substitute these values into equation 2

R' = 100/(2³⁶⁵⁰⁰/¹³⁸³⁹)

R' = 100/(6.222)

R' = 16.07 milligrams of plonium-210

The first and second question please..
kotykmax [81]
Ex 1
the number from 1 to 100, I'll call it x

= (((x + 11) * 6 - 3) / 3 + 5) / 2 - x
= ((6x + 66 - 3) / 3 + 5) / 2 - x
= ((6x + 63) / 3 + 5) / 2 - x
= (2x + 21 + 5) / 2 - x
= (2x + 26) / 2 - x
= x + 13 - x
= 13
finally geez

Ex 2
theres 16 teams. 
after a team that loses twice they're out.
1 should be left, therefor 15 teams should be out.
15 * 2 = 30,
there should be 30 or 31 games if the last team alive lost 1 game.
