Ten calculators cost $149.50. how much would 100 cost? 1000? 500?

for 100 it will be $149,500

Step-by-step explanation:

What you would do is... 149.50 is ten right? so do 149.50 divided by 10 to find the price for each calculator. then you will multiply the cost of each calculator by 100, 1000, and 500. hope this helps :)

The area of a sector of a circle can be calculated by using this formula:

A=(n/360)*pi*r^2

where n is the measure of the central angle of the sector in degrees. Since we are already given with the measurement of the central angle, we can substitute this to the above formula:

A=(30/360)*pi*r^2

Taking the value of pi as 3.14, then

A=(1/12)*3.14*r^2
A=0.2617*r^2

Just plug in the value of r. and you will get the area of the sector. Hope this helps!
