Answer: R47.66
Step-by-step explanation:
Assuming this amount of R42.42 is Indian Rupees, then the relevant VAT rate to use is 12.36% which is the VAT rate in India.
The VAT inclusive amount is therefore:
= 42.42 * ( 1 + tax rate)
= 42.42 * ( 1 + 12.36%)
= R47.66
Answer:
Area = s² = 4² = 16 sq. In.
Perimeter = 4s = 4(4) = 16 in.
Answer:
5:8
Step-by-step explanation:
the ratio equivalent to 5 / 8 is 5:8
Answer:
The number of buyers on the first day was approximately 324.
Step-by-step explanation:
In this case we have a initial number of shoppers "C" that we want to know and this grows at a steady rate of 20% per day, like a compound interest, we also know the total number of shoppers after 4 days, so we have the final amount of shoppers. We can use the formula for compound interest in order to calculate the number of shoppers in the first day as shown bellow:
M = C*(1 +i)^(t)
Where M is the total amount of shoppers, i is the growth rate and t is the time elapsed.
671 = C*(1 + 0.2)^(4)
671 = C*(1.2)^4
671 = C*2.0736
C = 671/2.0736 = 323.5918
Since there can't be a 0.59 buyer, we will round the number to 324.
Answer:
f(x) = 8 (x + ¼)² − ½
Step-by-step explanation:
f(x) = 8x² + 4x
Divide both sides by 8.
1/8 f(x) = x² + 1/2 x
Take half of the second coefficient, square it, then add to both sides.
(½ / 2)² = (1/4)² = 1/16
1/8 f(x) + 1/16 = x² + 1/2 x + 1/6
Factor the perfect square.
1/8 f(x) + 1/16 = (x + 1/4)²
Multiply both sides by 8.
f(x) + 1/2 = 8 (x + 1/4)²
Subtract 1/2 from both sides.
f(x) = 8 (x + 1/4)² − 1/2
