Robin earned $4,320 in 9 weeks and worked 40 hours in each week. how much did he earned per hour

$12 per hour

Step-by-step explanation:

4320 / 9 = 480 per week / 40 = 12 per hour

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.
