First image:

C, D, and E are true.

Second image:

30 tbsp

Step-by-step explanation:

1 cup = 8 ounces

A is false.

1 quart = 4 cups

7 qt = 28 cups

28 + 4 = 32

32 < 34

B is false.

1 gallon = 8 pints

4 gallons = 32 pints

31 < 32

C is true.

1 gallon = 4 quarts

5 gallons = 20 quarts

20 < 21

D is true.

1 quart = 2 pints

15 quarts = 30 pints

30 = 30

1 ounce = 2 tablespoons

15 ounces = y tablespoons

1 × y = 15 × 2

y = 30

30 tbsp

it could be 1,3 and more others to create a cylinder.

step-by-step explanation:

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
