Answer:
w = 21.4 ft
Step-by-step explanation:
Area of Trapezoid = Area = (a+b)/2 * h
Where a and b are the bases of trapezoid, and h is the height.
In the figure we are given:
a= 32.3 ft
b=w=?
h= 22.9 ft
Area = 614.865 ft²
Putting values in formula
Area = (a+b)/2 * h
614.865 = (32.3 + w) / 2 * 22.9
1229.73 = 32.3 + w * 22.9
1229.73 / 22.9 = 32.3 +w
53.7 -32.3 = w
=> w = 21.4 ft
The answer is 7. 9 + 5 / 2 equals to 7. 9 and 5 and the two middle numbers.
Answer:
x=9.5
Step-by-step explanation:
In order to find the answer, we know that 6x + 4x - 5 = 90
Next we want to combine like terms: 10x - 5 = 90.
Now we have to add 5 to 90 in order to get x on its own. 10x = 95
Now solve for x by dividing 95 by 10: x=9.5
256 x 3 is uhh 768 so it would be 2 of the 128 sticks
