Answer:
A = 12
Step-by-step explanation:
Given A is inversely proportional to B then the equation relating them is
A = 
To find k use the condition when A = 4, B = 36 , then
4 = 
( multiply both sides by 36 )
144 = k
A = 
← equation of variation
When B = A , then
A = 
( multiply both sides by A )
A² = 144 ( take square root of both sides )
A = ± 
= ± 12
Since A is a positive number then A = 12
The ratio for Figure 1 to Figure 2 is
13:66
26/2 = 13
132/2 = 66
That's how I found my ratio

Answer:
x = -48.
Step-by-step explanation:
40 + 4x = 3x - 8
4x - 3x = - 8 - 40
x = -48.
Answer: $427140
Step-by-step explanation:
Firstly, we'll add MP to the profit and this will be:
= Rs 400000 + Rs 20000
= Rs 420000
Since there is a discount of 10%, this will then be:
= 420000 - (10% × 420000)
= 420000 - 42000
= $378000
With a VAT of 13%, then the final price will be:
= $378000 + (13% × $378000)
= $378000 + (0.13 × $378000)
= $378000 + $49140
= $427140
