Given:
Height of man = 6 ft
Height of man's shadow = 11 feet
Height of building's shadow = 139 feet
To find:
The height of the building.
Solution:
We know that the heights of the objects and there shadows are always proportional.
Let x be the height of the building.
Multiply both sides by 139.
Therefore, the building is 75.8 feet long.
Answer:
The
90
adult tickets sold were
45
%
of the
200
tickets sold to the concert.
Explanation:
Since
90
tickets out of
200
were adult tickets, the percentage (represented as
x
) can be calculated by this equation:
200
×
x
100
=
90
2
200
×
x
100
=
90
2
x
=
90
Divide both sides by
2
.
x
=
45
Step-by-step explanation:
The area of the shaded region is 3.125π - 6. The correct option is E. 3.125π - 6
<h3>Calculating area </h3>
From the question, we are to determine the area of the shaded region
The area of the shaded region = Area of the semicircle - Area of the triangle
First, we will determine the diameter, d, of the semicircle
d² = 3² + 4² (<em>Pythagorean theorem</em>)
d² = 9 + 16
d² = 25
d = √25
d = 5
∴ Diameter of the semicircle is 5
Thus,
Radius, r = 5/2 = 2.5
Now,
Area of the shaded region = 1/2(π×2.5²) - 1/2(3×4)
Area of the shaded region = 1/2(π×6.25) - 1/2(12)
Area of the shaded region = 3.125π - 6
Hence, the area of the shaded region is 3.125π - 6. The correct option is E. 3.125π - 6
