Answer:
32.5 square feet
Step-by-step explanation:
The formula for a trapezoid is a= 1/2*(b1+b2)*h. B1 and b2 would represent the two bases given and therefore doesn't matter what order you put them in. Plug in all values into the equation and you'll get 1/2*(5+8)*5 then 1/2*(13)*5. Next simplify to get 6.5*5 which then equates to 32.5.
Given there are 12 parts in the ratio, we would divide 48 by 12 which equals 4. So, the ratio would be 28:20.
Answer:
13/50
Step-by-step explanation:
26/100 can be reduced to 13/50
Answer:
x=-5
Step-by-step explanation:
7x+35=0
subtract 35 from both sides
7x=-35
divide both sides by 7
x=-5
