$17 is the final answer.
explanation: If you times $1.28 By 12.99 your answer is $16.63 and if you round it up to 2 decimal places it's $17 as $16 and 63 cent is closer to $17 than $16
2/3 cause you are not changing the number itself so the opposite would just change the negative to a positive.
Answer:
12.71in
step explanation:
The Length of an arc given is expressed as;
A = theta/360 * 2πr
10 = 45/360 * 2 * 3.14r
10 = 1/8 * 6.28r
Cross multiply
10 * 8 = 6.28r
80 = 6.28r
r = 80/6.28
r = 12.74in
Hence the radius is 12.71in
