Answer:
Step-by-step explanation:
Data provided in the question
Number of bags of mulch = 7.5 bags
Number of square yards = 12
So by considering above information, we could find the number of bags for each square yard is
= 
= 
= 0.625
The 0.625 is equal to
bag
Therefore, she need to use

Answer:
8.95feet
Step-by-step explanation:
The set up is a right angled triangle where;
The camera's horizontal distance from the focus point = 26feet = Adjacent;
The height of the camera above the floor = Opposite = x
Angle of elevation = 19°
According to TOA in trig identity;
Tan theta = opp/adj
Tan 19 = x/26
x = 26tan 19
x = 26(0.3443)
X = 8.95feet
Hence the camera is placed at a height of 8.95feet above the floor
