$565+$65= 630
630/30 would be 21
it would take him 21 weeks to pay off his sister and buy the bike
Area = 140
16 x 8 = 128
16-12 = 4
(6x4)/2 = 12
128 + 12= 140
Answer:
$340
Step-by-step explanation:
The pool is 5 yards wide by 10 yards long, so adding the deck will make the total area 7 yards wide by 12 yards long, or ...
(7 yd)·(12 yd) = 84 yd^2
The pool itself is ...
(5 yd)·(10 yd) = 50 yd^2
so the area of the deck is ...
84 yd^2 -50 yd^2 = 34 yd^2
Wood for each of those square yards costs $10, so the total cost is ...
($10/yd^2)·(34 yd^2) = $340
Answer:
x=56.89
Step-by-step explanation:
The perimeter of a square is the sum of its sides and they
are all equal, so to obtain the length of each of them we divide the perimeter
of the first fence between 4:
P1= 64 feet/4 sides
P1= 16 feet
Then, the length of each side of the second fence will
increase 2 feet at each end, as shown in the figure. We have then that the
perimeter of the second fence is:
P2 = 20 feet x 4 sides
P2 = 80 feet
The sum of the perimeters of both fences is:
PT = P1 + P2
PT = 64 feet + 80 feet
PT = 144 feet
Total cost = 1.17 $ x 144 feet
Total cost = 168.48 $
The total cost of the fences was $ 168.48
