The sales tax would be $8.21 if you wanted full price because if you multiply $7.82 by 00.5 you get 0.391 to get *.21 just add $7.82 to 0.391
Answer:
8.2
Step-by-step explanation:
Use cosine law:
BC² = 7² + 9² - 2(7)(9)cos(60)
BC² = 67
BC = sqrt (67)
BC = 8.1853
BC = 8.2 (nearest tenth)
Answer:

Step-by-step explanation:
Convert text to an equation:
33 is 11 more than a
33 is 11 + a

Subtract 11 on both sides:

Answer:
9(m+H) = a
Step-by-step explanation:
m=a/9-H
The first step is to add H to each side.
m+H = a/9 -H+H
m+H = a/9
Now multiply both side by 9
9(m+H) = a/9*9
9(m+H) = a
