11. the expression 60(1 + ) represents the total bill including the tip. what do the different parts of the expression represent? match each expression to the correct description. 1) cost of meal a) x 2) tip percentage b) (1 + x) 3) number of friends c) 60

Its given that the total bill = 60(1 + x)

                                          = 60 + 60x

So, its clear that the cost of meal is 60 and the percentage of tips is x.

Also, number of friends = (total cost/cost per meal)

                                        = 1 + x

Hence, the correct match is:

1) - c)

2) - a)

3) - b)

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
