Answer: $40+$10x
Step-by-step explanation:
1. We already know he has $40.
2. 10x represent the 10 dollars he is paid per month.
Answer:
a). y = 4.5
b) Scale factor = 
Step-by-step explanation:
a). Since, polygon Q is the scaled copy of polygon P
Both the figures will be similar.
Therefore, their corresponding sides will be proportional.
If x = 6,
y = 
y = 4.5
b). Since, polygon Q is the scaled copy of polygon P,
Polygon Q will be the image of preimage polygon P.
Scale factor = 
=
The answer to 5 is A. And the answer to #6 is B. Here is why: So the cost for 6 pens is $2.34. So, you want to find the unit rate. The unit rate basically, in this case, would be how much on pen costs. So to find how much one pen costs you would divide 6 into $2.34. That would give you .39¢. Now to find out how much 20 pencils would cost you would multiply .39¢ by 20. This would give you $7.80. Do you see it now? I hope this could be helpful!
Given that point of intersection is at halft ot the heigth, by similarity of triangles, the radius is halft of 6 in, i.e 3 in.
The the area is Pi*r^2 = Pi*(3in)^2 = Pi*9 in^2 = 9Piin^2
This is option C)
