tickets cost $2 each. she wants to go on a minimum of 10 rides and play at least 12
games. which system of inequalities represents this situation when r is the number of
ride tickets purchased and g is the number of game tickets purchased?
3) 1.25r+2g 550
r210
1) 1.25r.+ 2g < 50
r310
g > 12
2) 1.250+2g 3 50
r10
4) 1: 25r+ 2g < 50
310
g 212
g 2 12

The areas of two similar triangles are 72dm2 and 50dm2. the sum of their perimeters is 226dm. what is the perimeter of each of these triangles?

Consider a bag that contains 220 coins of which 6 are rare indian pennies. for the given pair of events a and b, complete parts (a) and (b) below. a: when one of the 220 coins is randomly selected, it is one of the 6 indian pennies. b: when another one of the 220 coins is randomly selected (with replacement), it is also one of the 6 indian pennies. a. determine whether events a and b are independent or dependent. b. find p(a and b), the probability that events a and b both occur.
