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
It’s the position on the graph. So quadrant 1 is (x,y)
Quadrant 2 is (-x,y)
Quadrant 3 is (-x,-y)
Quadrant 4 is (x,-y)
Answer:
So, to change a mixed number into a decimal, first you have to divide the numerator by the denominator then add the whole part of the mixed number. (Wow I just learned something new!)

Step-by-step explanation:
Suplemtary angle must be 90 degrees
Therefore if we have 105 degress, the suplementary angle is 75
