Answer: R12.20
Step-by-step explanation:
VAT in South Africa is 15% so if the flat rate is R93.57, the VAT amount can be found by finding the pre-tax flat rate:
93.57 = x + 0.15x
1.15x = 93.57
x = 93.57/1.15
x = R81.37
VAT is 15% of R81.37:
= 15% * 81.37
= R12.20
Answer:
Step-by-step explanation:
1. b+6=
Because Abby 6 more books than Kristen. The amount of book Kristen reads is represented with b.
2.Sorry I don't get the rest.
The zeros of function are x-s, for which f(x) = 0:

<span>To do these you will be adding or subtracting 2pi (or integer multiples of .
Since the given angles are in fraction form, it will help to have 2pi in fraction form, 2pi=10/5=6pi/3=4pi/2=18pi/9 NOTE: this>(/) stands for over like 1 over 2 EX. 1/2
too, so the addition/subtraction is easier.
Hint: When deciding if you have a number between 0 and 2pi, compare it to the fraction version of 2pi that you've been adding/subtracting.
For 17pi/5...
First we can see that 17pi/5 is more than 10pi/5 (aka 2pi). So we need to start subtracting: 17pi/5 - 10pi/5 = 7pi/5
Now we have a number between 0 and 10pi/5. So 7pi/5 is the co-terminal angle between 0 and 2pi.
I'll leave the others for you to do. Just remember that you might have to add or subtract multiple times before you get a number between 0 and 2pi.
P.S don't add or subtract at all if the number starts out between 0 and 2pi.</span>
