To get perimeter you add all the sides together. You have 2 sides of 10ft, one side of 8ft and then the half circle. To find the arc length of the half circle you would do 1/2(2πr) which would give you πr. R=4ft since the diameter is 8ft. So you would add 8,10,10 and 4pi. If it wants an exact answer it would be 28+4pi. If it wants an approximate answer it would be 40.6ft
The correct answer is $10,982.68, because you have to subrtract $666.66 from $6,008.10 and you would get $5,341.44. The next step is that you have to add because the problem states that they're depositing, (which means putting money into the bank account), so you add the $1,100.10 and the $4,580.54 to $5,341.44 and you would get $11,022.08. Lastly the last step is to subtract the cost of the checks from your total and you would get $10,982.68.
Hope that helps.
The answer to the question is ORTHOCENTER. The altitude is the line that connects the vertex of a triangle to the opposite side making a 90 degrees with it. Thus, the use of the prefix ortho- for the points where the three altitudes meet.
7 - 3 1/4 = (turn mixed number to improper fraction
7 - 13/4 = (common denominator is 4)
28/4 - 13/4 =
15/4 or 3 3/4 gallons remain in the tank
