If a pencil factory makes 50 cases of pencils in 5 hours. Let's first find out how many cases are made per hour.
50 ÷ 5 = 10 cases per hour
Now you need to know how long it will take to make 55 cases. Since we already know that it takes 5 hours to make 50 cases. So you need to know how many cases for the extra 5 cases. If it takes 1 hour to make 10 cases, it would only take 1/2 hour to make 5 cases.
So it would take 5 1/2 hours to make 55 cases.
Hope this helps. :)
Multiply the numerators: 7×8=56 then the denominators 10×21=210. The lowest multiples for 56 and 210 is 14. So divide 56/14=4 and 210/14=15. Your answer is 4/15.
Hope this helps (:

Answer:
128 ft²
Step-by-step explanation:
The formula for the area of a trapezoid applies:
A = (1/2)(b1 +b2)h . . . . . where b1, b2 are the base lengths and h is the height
For Alex's dimensions, the area is ...
A = (1/2)(14 ft +18 ft)(8 ft) = 128 ft²
