A cellphone company charges $17 plus $0.25 for each text message sent. The total bill
was $45.50. How many text messages were sent?

114 text messages

Step-by-step explanation:

Set up an equation:

45.50 = .25x + 17

Where x is the number of text messages sent

Subtract 17 on both sides:

45.50 = .25x + 17

-17                   -17

28.50 = .25x

Divide by .25 on both sides:

28.50 = .25x

/.25        /.25

114 = x

answer: h

step-by-step explanation:

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
