Answer:
d. 92.84
Step-by-step explanation:
The top edge overhangs the bottom edge by (39 -27)/2 = 6 ft on both ends. This makes the slant side have length
.. √((6 ft)^2 +(12 ft)^2) = 6√5 ft
Then the perimeter is
.. (39 +6√5 +27 +6√5) ft = 66 +12√5 ft
= 92.83 ft
Answer:
83,403
Step-by-step explanation: Take 74,145 and multiply it by 4%. Then take that number and add it to the 74,145 and that'll give you year one. For year 2 you'll take your total from year 1 and multiply it by the 4% growth rate then you'll add the 4% to what your ending from year 1 and that'll give you your total growth after 2 years. Then you'll take your ending total from year 2 and multiply it by 4% and then you'll add that 4% to the total end from year 2 and that'll give you your total growth of 4% every year for 3 consecutive years.
Hope this helps!
