A long distance call costs $.50 for the first minute and y cents for additional minute. How much does each additional minute cost if the bill was $5.60 and you talked for 10 minutes

$.56

Step-by-step explanation:

The first minute is .50 cents and the subtotal was 5.60. Subtract for the first minute to get the subtotal for 9 minutes.

(5.60-.50=5.10)

5.10 is the amount for 9 minutes so now we will divide to get the price for each minute.

(5.10÷9=.56)

This means each minute after the first minute is $.56 cents.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
