Jovelle, Michelle and Mark had 144 marbles with the ratio of 3:1:4 respectively. How many marbles does Mark have?

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.

the answer should be 3.54 g/cm^3

answer:

the product of -35 and -625 is positive.
