When the vat rate is 15% a customer pays 1610 to buy an electric iron .find the cost of the iron without vat (solve by video)

Cost without vat is 1,368.5

Step-by-step explanation:

Here, we want to know the cost of the iron without the vat.

From the question , we can see that 15% VAT brought the cost to 1610.

This means that the original cost without vat is 100% -15% = 85% of the total

Thus;

85/100 * 1610 is the cost without vat

And that is;

136850/100 = 1,368.5

a) 32pie square meters

step-by-step explanation:

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
