Evan's mother used 1/3 pound of beef, 1/2 pound of shrimp, and 3 pounds of pasta to make dinner for 4 people. use this information to answer all four parts below. question: part a: each person will receive an equal share of beef with none left over. what is the amount, in pounds, of each serving of beef? part b: each person will receive an equal share of shrimp with none left over. what is the amount, in pounds, of each serving of shrimp? part c: each person will receive an equal share of pasta with none left over. what fraction represents the amount, in pounds, of each serving of pasta? part d: evan only ate 1/2 of the pasta that he received. what is the amount, in pounds, of pasta did evan eat? explain how you got this answer step-by-step using math vocabulary.

Quantity of Beef used = 1/3 pounds

Quantity of Shrimp used = 1/2 pounds

Quantity of pasta used = 3 pounds

Total number of people for dinner = 4

Part A:

Since all 4 people need equal serving of beef, so dividing 1/3 pound by 4 , we will get 1/12 or 0.0833...

Each person will get 1/12 or 0.0833.. pound of beef.

Part B:

Since all 4 people need equal serving of shrimp, so dividing 1/2 pound by 4 , we will get 1/8 or 0.125 pound.

Each person will get 1/8 or 0.125 pound of shrimp.

Part C:

Since all 4 people need equal serving of pasta, so dividing 3 pound by 4 , we will get 3/4 or 0.75.

Each person will get 3/4 or 0.75 pound of pasta.

Part D:

Evan only ate 1/2 of the pasta that he received.

Pasta received by Evan = 0.75 pounds.

He ate half of what he received, so half of 0.75 pounds is 0.375 pounds.

Evan ate 0.375 pounds of pasta.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

3x + 4y -25 =0 represents the amount of change sianna should recieve
