2. A cup of coffee costs $2.50. If the total cost is $17.50, then how many cups of coffee were
purchased?
a. Write an equation:
b. What is the constant of proportionality?

Help please

The constant is 2.50

I believe the equation would look like 2.5x=17.5

and x would equal 7

step-by-step explanation:

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
