Answer:
The distance between the parallel sides is 20cm.
Step-by-step explanation:
Area of a trapezoid:
where a and b are the 2 bases, and h is the height. The value we're trying to find here is the height.
3 of the 4 variables in this equation are already given:
A = 800
a = 48
b = 32
Just plug those in and solve for h:
First add 1 to both sides, thus making it 4r=36 then divide both sides by 4, making r=9.
4r-1=35
+1 +1
4r=36
4 4
r=9
Answer:

Step-by-step explanation:
— Round tables will have 6 chairs, rectangular tables will have 10 chairs, the total number of chairs must be at least 185: 6x +10y ≥ 185
— There be no more than 15 rectangular tables: y ≤ 15
— No fewer than 6 round tables: x ≥ 6
— Rectangular tables must be at least 1/3 the number of round tables: y ≥ (1/3)x ⇒ 3y ≥ x
3B - 18 = 9 (B - 18)
3B - 18 = 9B - 162
6B = 144
B = 24
3B = 72
Brandon is 24 and Michael is 72.
