Answer:
10 percent

40000 is the old value and 44000 is the new value. In this case we have a positive change (increase) of 10 percent because the new value is greater than the old value.
Answer:
32 ft
Step-by-step explanation:
find the area of the large rectangle:
30 x 16 = 480
find the area of the small rectangle:
10 x 8 = 80
subract the small rectangle from the big rectangle to get the area of the shaded region:
480 - 80 = 400
now plug this area and the height into the equation for triangle area:
A = bh/2
400 = b(25)/2 multiply both sides by 2
2(400) = 2(25b/2)
800 = 25b divide both sides by 25
800/25 = 25b/25
32 = b
