Describe any pattern you see in this sequence of ordered pairs: (1,1800), (2,900), (3,300), (4,100)

the bottom of the spinner is not flat.

step-by-step explanation:

134.6 us dollars

step-by-step explanation:

1 us dollar = 1.33 canadian dollars

so, 150 us dollars = 150 × 1.33 = $199.5.

in canada, the money mitchell spent = 20 canadian dollars.

remaining canadian dollars with him = 199.5 - 20 = 179.5.

after mitchell returned to us, he exchanged the remaining canadian dollars to us dollars.

179.5 canadian dollars = 179.5 × 0.75 = 134.6 us dollars.

simple 80 pieces in 1 sercing so 80*47=3760+20=3780
