0.98 * 5 = $4.9
total = $4.9 + $19.29 + $ 14.25 = $38.44
answer: Total cost = $38.44
EQUATION OF A CIRCLE = (x-h)² + (y-k)² =r²
In this case, since the center of the cercle is in O, then h=0 & k=0
x²+y² = 64
1 is the answer
hopefully this is correct because i know i am :)
The answer is 25 13/20 square feet.
In order to complete this operation, it is first best to change your mixed numbers into improper fractions.
7 1/8 = 57/8
7 1/5 = 36/5
Now that we have these, we can put them into the triangle formula.
A = 1/2bh
A = (1/2)(57/8)(36/5)
A = 1026/40
You can then simplify this fraction by dividing the top and bottom by a factor of 2.
A = 513/20
Then, because we know 20 goes into 500, 25 times, we can pull that out and be left with a remainder of 13/20.
A = 25 13/20
