10% of $15 = 15/10= 1.5
1.5 x 2= 3 = 20%
15-3=12
Therefore the towel will be $12 with a 20% of coupon
The answer is B because u always start of like that
Answer: 31.43 cm
Step-by-step explanation:
The length of an arc is calculated using the formula:
X 2r
where : theta is the angle in degree
r = radius
If the angle is given in Radian , the length can be calculated using the formula:
L = r∅
Since , the angle is given in degree , we will use the first formula.
L = X 2r
L = X 2 X π X 15
L = X 2 X X 15
L =
L = 31.42857143
L ≈ 31.43 cm
905 whatever that is (I forgot)
1/2 because everything lose half its value points wise.
