Which continent is estimated to have more than 5.31 billion people by 2050? To solve find what percent 5.31 is of billion is of
emmasim [6.3K]

The continent which has 59% of the total population will have more than 5.31 billion people by 2050.

<u>Step-by-step explanation:</u>

It is given that,

  • The total number of people is 9 billion.
  • The estimated number of people in 2050 year is 5.31 billion.

Therefore, you need to find out which continent has the estimated number by finding the percentage value.

<u>To find what percent 5.31 is of billion is of 9 billion :</u>

Let x be the percentage to be calculated.

⇒ x percent of 9 billion is 5.31 billion.

⇒ (x/100) × 9 = 5.31

⇒ x = (5.31 × 100) / 9

⇒ x = 531 / 9

⇒ x = 59 %

∴ The continent which has 59% of the total population will have more than 5.31 billion people by 2050.

Using addition formula solve tan 15​
salantis [7]

Answer:

2 - \sqrt{3}

Step-by-step explanation:

Using the addition formula for tangent

tan(A - B) = \frac{tanA-tanB}{1+tanAtanB} and the exact values

tan45° = 1 , tan60° = \sqrt{3} , then

tan15° = tan(60 - 45)°

tan(60 - 45)°

= \frac{tan60-tan45}{1+tan60tan45}

= \frac{\sqrt{3}-1 }{1+\sqrt{3} }

Rationalise the denominator by multiplying numerator/ denominator by the conjugate of the denominator.

The conjugate of 1 + \sqrt{3} is 1 - \sqrt{3}

= \frac{(\sqrt{3}-1)(1-\sqrt{3})  }{(1+\sqrt{3})(1-\sqrt{3})  } ← expand numerator/denominator using FOIL

= \frac{\sqrt{3}-3-1+\sqrt{3}  }{1-3}

= \frac{-4+2\sqrt{3} }{-2}

= \frac{-4}{-2} + \frac{2\sqrt{3} }{-2}

= 2 - \sqrt{3}
