Explanation

To find speed, convert the time to hours and distance to kilometers:

Time = 2 minutes 30 seconds = 2.5 minutes = 2.5/60 = 1/24 hours

Distance = 750 meters = 0.75 kilometers

Speed = Distance / Time = 0.75 / (1/24) = 0.75 x 24 = 18 km/hr

Explanation

Vertical angles are equal, so set up an equation:

80° = 4x

Divide both sides by 4:

x = 80° / 4

x = 20°

Explanation

Given the proportion:

a³ - b³ : a² - b² :: a² + ab + b² : x

We know a³ - b³ = (a - b)(a² + ab + b²) and a² - b² = (a - b)(a + b)

So, the proportion becomes:

(a - b)(a² + ab + b²) : (a - b)(a + b) :: a² + ab + b² : x

Canceling (a - b):

(a² + ab + b²) : (a + b) :: a² + ab + b² : x

This implies x = a + b.

Explanation

892 squared, (892)2, is the number you get when multiplying 892 times 892.

It can also be looked at as exponentiation involving the base 892 and the exponent 2.

The square of 892 is a perfect square because the number is the product of the two equal integers 892.
