Heart Lake Developments sold four lakefront lots for $ per hectare. If the sizes of the lots in hectares were , , , and respectively, what was the total sales revenue for the four lots?

$423042

Step-by-step explanation:

Here's the complete question:

Heart Lake Developments sold four lakefront lots for $27,500 per hectare. If the sizes of the lots in hectares were 5 1/2, 2 4/5, 2 3/4 and 4 1/3 respectively, what was the total sales revenue for the four lots?

This will be:

= 5 1/2 × 27500 = 151250

= 2 4/5 × 27500 = 77000

= 2 3/4 × 27500 = 75625

= 4 1/3 × 27500 = 119167

Total sales = 151250 + 77000 + 75625 + 119167 = 423042

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
