The second is the correct one
Your answer should be A, sorry if that’s incorrect it just makes the most sense! :)
Use the formula for the length of an arc:-
L = r C where r = radius and C = angle subtended in radians So here we have:_

18 = 2.269 r
r = 7.93 cm to neraest hundredth
Answer:
The original price is $409.5
Step-by-step explanation:
the 2 numbers that you have in this equation are 315 and 30% (or .30)
You want to multiply 315 by .3 to get an answer of 94.5
That's the amount of money that was marked down on the guitar
So you want to add 94.5 to 315 which gives you 409.5
so $409.5 is your answer
Answer:
B
Step-by-step explanation:
10% of 49.99
0.1 x 49.99 = 4.99
49.99 - 4.99 = 45.00
30% of 60.00
0.3 x 60 = 18
60 - 18 = 42.00
