A chef placed an order for 50 pounds of fish. He calculated that he will need 20 3/5 pounds for lunch orders. How much fish will the chef have left for dinner orders?

29 2/5

Step-by-step explanation:

We know that 5 fifths make up a whole. The chef only needs 3/5 of that whole, so we still have 2 fifths remaining. Now, we have to subtract 50 by the number of lunch orders, 20. 50 subtracted by 20 is equal to 30, but we have to subtract a whole because of the fraction. We get the number 29. Then, we add the remaining fraction back. We get the answer as 29 2/5.

Best of Luck!

the answer to your question is c.)   volcanoes built the mountains and earthquakes tore them down.

step-by-step explanation:

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
