Answer: 17.9 km/h
Step-by-step explanation:
Convert 33 minutes and 50 seconds to Hours:
= 33 ⁵⁰/₆₀ minutes
= 33.83 minutes
In hours that would be:
= 33.83 / 60
= 0.56 hours
10,000 meters in kilometers is:
= 10,000 / 1,000
= 10 kilometers
Speed = 10 / 0.56
= 17.9 km/h
Answer:
12 ft
Step-by-step explanation:
we know the areas of the 2 top squares.
the area of a square is simply the square of its side length.
=>
81 ft² means side length is 9 ft.
225 ft² means side length is 15 ft.
these are also 2 of the sides of the right triangle.
the third side we get by using Pythagoras :
c² = a² + b²
with c being the side opposite of the 90 degree angle.
so,
225 = 81 + x²
as x is also the third side of the triangle.
=> 144 = x²
x = 12 ft
