I have 5 questions. <,>,or =. 67 miles____116,920 yards, 250 yards____800 feet, 14 yards and 2 feet_____16 feet, 34 feet 10 inches_____518 inches, 5 miles and 8 feet______8,800 yards. Please answer 3/5 of the questions

Answers

1 mile=1,760 yards
67 miles = 117,920 yards
that's > 116,920 yards

1 yard=3 feet
250 yards = 750 feet
that's < 800 feet

1 yard = 3 feet
14 yards = 42 feet
plus another 2 feet = 44 feet
that's much > 16 feet

1 foot = 12 inches
34 feet = 408 inches
plus another 10 inches = 418 inches
that's < 518 inches

1 mile = 1,760 yards
5 miles = 8,800 yards
that's already = to 8,800 yards, and we haven't even stuck the extra 8 feet on yet
when we do that, it'll be > 8,800 yards by exactly 8 feet (2 and 2/3 yards)

Dominic uses 1/2 tablespoon of almond butter to make a sandwich he needs to make five sandwiches how many tablespoons of almond butter does Dominic need to make the sandwiches

Answers

Well, we first know that Dominic uses 1/2 tablespoon. So if we use that 1/2 tablespoon on two sandwiches how many tablespoons does Dominic use? A whole! If you make another two sandwiches, then it will make another whole, and I whole plus one whole equals two wholes. Then, you make another one which uses another 1/2. And 1 whole plus one whole plus 1/2 a tablespoon equals 2 1/2!

there are 118 boys and 121 girls signed up for a volleyball league. The coaches first make teams of 9 players and then assign any remaining players to make some of the teams have 10 players.how many teams of 10 players. how many teams of 9 players

Answers

The number of nine-players team= 21 teams.

The number of ten-players team= 5 teams.

Step-by-step explanation:

step 1: The total players signed up for a volleyball league= 118 boys+121 girls= 239 players.

step 2: The coach first makes a 9 players team= 239-9= 230 members

In this stage, the number of 9 players-team is one.

step 3: The remaining 230 players cannot be divided equally into 9 players, since 230 is not divisible by 9.

step 4: Find the number within 230 that is divisible by 9 as a whole. Check for easy number (9*20= 180 is within 230)

Therefore, 230-180= 50 players are remaining.

In this stage, the number of 9 players-team= 1+20= 21 teams with 9-players.

The number of 10 players-team= 50 players/10= 5 teams with 10-players.
