Answer:
20 square units
Step-by-step explanation:
If Polygon C has an area of 40 square units, and we are told that Polygon D is a copy of Polygon C but with a scale factor of 1/2, then everything for Polygon D would just be one-half of what it was for Polygon C. Thus, the area would be half of 40 square units, or, 20 square units.

Step-by-step explanation:
Step one:
The farmer sells his corn for $230 a metric ton
small surcharge = $25.
let the amount per metric ton be x
and let the total cost per x metric ton be y
the total cost function is
y=230x+25--------------1
The neighbor sells her corn for $230 a metric ton
he gives $15 rebate------<em>A rebate is a partial refund of the cost of an item</em>
let the amount per metric ton be x
and let the total cost per x metric ton be y
the total cost function is
y=230x-15----------------2
Step two:
Equating the two equation above
230x+25=230x-15
230x-230x=25+15
0=40
The result shows that based on the cost function of both farmer, there will never be an amount of corn that would make them have the same cost
Answer:
10rupee notes are 11
20rupee notes are 22
Step-by-step explanation:
Let 10-rupee note be x
20-rupee note will be x + 11
The equation will be
10x + 20(x + 11) = 550
10x + 20x + 220 = 550
30x = 330
x = 330/30 = 11 = 10rupee notes
y = 11+11 = 22 = 20rupee notes
