For a chess tournament, there needs to be 3 teachers for every 18 students. If there are 11 teachers, how many students can go to the chess tournament?
What is the constant of proportionality? You can think about this as 18 is how many times as much as 3.
Number of Teachers Number of Students
3
×
18
11

Step-by-step explanation:

Solution:

Given,

3 Teacher = 18 students

11 Teacher = X students ( let no. of student be x)

Now,

1 teacher = 18/3

= 6 students

So, If 1 teacher is there then 6 students can play chess.

again,

No. of teacher = 11

No.of students = X

Now,

X= No.of teacher × No.of students for 1 teacher.

= 11 × 6

= 66

So , 11 Teachers can handle 66 students.

There propotion is 11/66 = 1/6 = 1:6.

Answer:

1:6 is the answer

The graph shows the prices, in dollars, of different numbers of sandwiches at Juan's store. The table shows the prices, in dollars, of different numbers of scones at the same store.

A graph shows Number of Sandwiches on x-axis and Price of Sandwiches on y-axis. The x-axis scale is shown from 0 to 36 at increments of 6, and the y-axis scale is shown from 0 to 240 at increments of 30. A straight line joins the ordered pairs 6, 30 and 12, 60 and 18, 90 and 24, 120 and 30, 150 and 36, 180.

Hannah and Corrine are playing a game by rolling two cubes, each numbered 1 through 6. If the sum of the numbers on the cubes is 7, Hannah wins. If the sum is not 7, Corrine wins. Corrine says Hannah can win only if the following occurs:

1 on the first cube, 6 on the second cube
2 on the first cube, 5 on the second cube
3 on the first cube, 4 on the second cube

Which best explains if Corrine is correct?

Corrine is correct because there are only three ways to have a sum of 7 when the cubes are rolled.

Corrine is correct because there are no 7s on the cubes, so Hannah must roll a greater number on the second cube.

Corrine is not correct because Hannah can also roll doubles on the cubes, such as 3 on the first cube and 3 on the second cube or 4 on the first cube and 4 on the second cube.

Corrine is not correct because Hannah also wins if 6 is on the first cube and 1 is on the second, if 5 is on the first cube and 2 is on the second, and if 4 is on the first cube and 3 is on the second.

In baseball, each time a player attempts to hit the ball, it is recorded. The ratio of hits compared to total attempts is their batting average. Each player on the team wants to have the highest batting average to help their team the most. For the season so far, Jana has hit the ball 12 times out of 15 attempts. Tasha has hit the ball 9 times out of 10 attempts. Which player has a ratio that means they have a better batting average?

A:Tasha, because she has the lowest ratio since 0.9 > 0.8
B:Tasha, because she has the highest ratio since 27 over 30 is greater than 24 over 30
C:Jana, because she has the lowest ratio since 0.9 > 0.8
D:Jana, because she has the highest ratio since 27 over 30 is greater than 24 over 30
