Question:
a. Twenty-three ninth graders and fifteen eleventh graders prefer math.
b. Fourteen eleventh graders prefer math and eight tenth graders prefer English.
c. Thirty-five twelfth graders prefer math and nine tenth graders prefer English.
d. Twenty-three ninth graders and thirty-five twelfth graders prefer math.
e. Eighteen tenth graders prefer English and fourteen eleventh graders prefer math.
Answer:
Therefore, the correct options are;
b. and d.
Step-by-step explanation:
Here we have a table with blank boxes and totals from which we can fill the boxes;
For the 12th graders, we have a total of 67 pupils with 32 preferring English, therefore the number of the 12th graders that prefer math is 67 - 32 = 35 pupils
Similarly for the 11th graders we have total pupils = 29 with 15 preferring English, therefore the number of the 11th graders that prefer math is 29 - 15 = 14 pupils
Also for the 10th graders we have total pupils = 26 with 18 preferring math, therefore the number of the 11th graders that prefer English is 26 - 18 = 8 pupils
Finally for the 9th graders, we have a total of 63 pupils with 40 preferring English, therefore the number of the 9th graders that prefer math is 63 - 40 = 23 pupils
From the above, the correct option is
Answer:
b only

What is cube?
- It is a symmetrical three dimensionalshape containing 6 equal squares
How to solve the problem?
- This problem can be solved by following steps
- The volume of the aquarium given is 33.75 gallons
- The length of the aquarium given is 2 feet
- The height of the aquarium given is 1.5 feet
- We need to find the width of the aquarium
As we know that aquarium is made of cube shape
So , The volume of a cube = length*width*height
Let the width be x
Therefore ,
33.75=2*x*1.5
33.75 = 3x
Therefore , x = 11.25 feet
Hence the width is 11.25 feet

The requried 3 divided by 14 in fraction form is 3/14.
What is the fraction?
A fraction is a mathematical concept that can be used to express a portion of a whole or a number that can be written as the ratio of two integers. In a fraction, the top number is referred to as the numerator, while the bottom number is referred to as the denominator.
Here,
As mentioned in the question, 3 divided by 14 in fraction form is given as,
a = 3, b = 14
fraction = a/b
fraction = 3/14
Thus, the requried 3 divided by 14 in fraction form is 3/14.

Answer: That would be demonstrated as 3/14, or 3 over 14
Step-by-step explanation:
The numerator is the number being divided, and the denominator is the divider. So if I were to write 1/2, 1 is being divided by 2, which results with .50. .50 is half of the whole number 1, make sense? :)
