S=r*theta where s is arc length and the r is radius and theta is in RADIANS ONLY!! If you use degrees this formula does not work.
So we have a arc length of 38.485ft and a radius of 7. So rearranging the formula for theta, we get;
theta=(38.485)/(7)= 5.498radians then to convert to degrees if needed just take;
5.498rad*(180/pi)= 315deg
-14 + 6b + 7 - 2b= 1 + 5b
combine like terms
-7 +4b = 1 + 5b
subtract 4b from each side
-7 + 4b -4b = 1 + 5b -4b
-7 = 1 + b
subtract 1 from each side
-7 -1 = 1-1 + b
-8 = b
Answer:
tax = .45
total cost = 4.95
Step-by-step explanation:
The price before tax is 4.50
The tax rate is 10%
The tax is
4.50 * 10%
4.50 * .10
.45
Add the tax of .45 to the total price
4.50 + .45 = 4.95
