Ymorist [56]
To construct a perpendicular bisector  you set the compass to a span which is greater than half the length of the given line.  Then setting the point at one end of the line construct an arc  passing through the line . Then repeat this process from the other side of the line keeping the compass at the same setting.

Now draw the perpendicular  bisector through the 2 intersections of the arcs. That's  it.

a boat costs 11,850 and decreases in value by 10% per year. how much will the boat be worth after 8 years
lawyer [7]
If the boat initially cost $11850 and INCREASED in value by 10% per year, we'd calculate the final value like this:

V = $11850(1+0.10)^8

But if the boat is losing value (depreciating) over time, we'd calculate its final value like this:

V = $11850(1-0.10)^8  =  $11850(0.90)^8 = $11850(0.4305) = $5101.04 (answer)

P=\frac{5!}{6!}=0.1667

The probability is 0.1667.

Work out the number of sides tile A has.<br> Both tile A and tile B are regular polygons
finlep [7]

Answer:

12

Step-by-step explanation:

since tile B is a regular polygon means it is an equilateral triangle. The angle inside B would be  60.

(360 - 60)/2 = 150 (interior angle of tile A)

180 - 150 = 30 (exterior angle of tile A)

therefore number of sides = 360 /30 = 12
