In a sale, all normal prices are reduced by 15% The normal price of a food processor is reduced by 13.50 dolllars.
Work out the normal price of the food processor.

24.98

Step-by-step explanation:

13.5 is 15% of the original price

multiply 13.5 by 1.85 to get the full price

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
