Given the following information, calculate the perimeter of Triangle RST. Assume Triangle RZX is similar Triangle RST.
RZ = 28, RY = 32, RX= 40. ZY = 16, and SW = 24

Possible answers:
139
128
109
150
None

150

Step-by-step explanation:

The ratio of ZY to SW is 16:24, meaning it is 2:3, so all of the sides of RST are 1.5 times as long as RZX.

RZ = 28, so RS = 42

RX = 40, so RT = 60

ZX= ZY + XY and since they are the same length, ZX = 32, making ST = 48

The perimeter is 42 + 60 + 48 = 150

yes

step-by-step explanation:

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
