What does X=?<br> I cannot figure out how to solve this problem please help!
Alona [7]

Answer:

Step-by-step explanation:

S = (n - 2).180°

n = quantity of sides

S = all angles addition

S = (5 - 2).180°

S = 3.180°

S = 540°

104 + 117 + 100 + 124 + x = 540

445 + x = 540

x = 540 - 445

x = 95°

I hope I've helped you.

The population density of the world is calculated by finding the ratio of the total number of people in the world to the area of
Romashka [77]

Answer:

51

Step-by-step explanation:

A = Surface area of the Earth = 1.5\times 10^8\ \text{km}^2

Total number of people on Earth = 7.594 billion as of 2018 = 7.594\times 10^9

We need to find the number of people living in each square km of land area.

So, we need to divide the number of people by the land area of the Earth.

1.5\times 10^8\ \text{km}^2=7.594\times 10^9\ \text{people}

\Rightarrow 1\ \text{km}^2=\dfrac{7.594\times 10^9}{1.5\times 10^8}

\Rightarrow 1\ \text{km}^2=50.63\approx 51\ \text{people}

So, 51 people will inhabit each square km of land area.

245, if x represents the number of minutes then you use 5 where x would be in the function so 49(5) which is 245 jumping jacks in 5 minutes.
