Answer:
30.11 meters ( approx )
Step-by-step explanation:
Let x be the distance of a point P ( lies on the building ) from the top of the building such that AP is perpendicular to the building and y be the distance of the building from point A, ( shown in the below diagram )
Given,
Point A is 8.20 m above level ground,
So, the height of the building = ( x + 8.20 ) meters,
Now, 1 degree = 60 minutes,
⇒ 
By the below diagram,
Now, again by the below diagram,
Hence, the height of the building = x + 8.20 = 30.11 meters (approx)

Answer:
3. 15 Cubes
4. 60 ft per sec , 180 ft
5. 58 yards per min
6. $7.50, $18.00
Step-by-step explanation:
3. Number of Cubes in 7 bowls = 35
Number of Cubes in 1 bowls = 
Number of Cubes in 3 bowls =
4. Distance ran by Zebra = 420 ft
Time taken = 7 seconds
Speed = 
=60 ft per sec
Hence
Distance = speed x time
Distance covered in 30 seconds = 60 x 30 = 180 Ft
5. Distance travelled = 870 yards
Time taken = 15 mins
Speed =
yards per min
6. Cost of 3 pounds of apple = $4.50
Cost of 1 pounds of apple = 
=$1.50
Cost of 5 pounds of apple = 5 x $1.50 =$7.50
Cost of 12 pounds of apple = 12 x $1.50 =$18.00
-11 = -2 + x/4
x/4 = -11 + 2 = -9
x = 4(-9) = -36
