Answer: they have 68 servings of ice cream left for the party

Step-by-step explanation:

The Smiths purchased 6 containers of ice cream for a party. Each container holds 9 cups of ice cream. This means that the total number of cups of ice cream that they have is

6 × 9 = 54 cups

Before the party, their sons ate 3 cups of ice cream altogether. This means that the number of cups of ice cream that they have left is

54 - 3 = 51 cups

One serving is 3/4 cup of ice cream. This means that the number of serving that they have left is

51/0.75 = 68

Two ice skaters started on opposite ends of a 200-foot-long rink and then skated toward each

SSSSS [86.1K]

Answer:

The proportion that can be used to find x is;

(200-x)/x = 7/6

Step-by-step explanation:

Now, we want to find the proportion which can be used to find x.

From the question, we are told that the father skater traveled 7 ft for every 6 ft of the slower skater;

this means that the ratio of their speed is 7:6

Now, when they passed each other , the slower skater has traveled x ft, what this means is that the faster skater will have traveled a distance of (200-x) ft at that moment they passed each other.

Mathematically, since their time is equal i.e the time they used to pass each other, then, the ratio of their distances is same as the ratio of their speeds;

Hence;

(200-x)/x = 7/6 or x/(200-x) = 6/7
