Calculate the VAT amount that is included in the R93,57 monthly flat rate for the UNMETERED residential area

Misha Larkins [42]

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

PLEASE HELP!!! I WILL GIVE BRAINY!!!

The first one is 4/3

We can solve by,

${x}^{2} \times 180 = 320$

$x = \frac{4}{3}$

${ \frac{4}{3} }^{2} \times 180 = 320 = true$

~~

The second one is 35.

Idk how to explain...

~~

The third one is a 6 - gon therefore cannot be C or D.

I'd say the third one is A., it looks like it's caving in.

What is the common rule for simplifying a negative exponent with a coefficient?<br> Ex: 3^-1

rjkz [21]

Anything to a negative power becomes the inverse with the coefficient to a positive power.
For example, 3^-1 becomes 1/3^1 or just 1/3.
3^-2 would be 1/3^2 or 1/9.
