A sample of students is taken from the school's A honor roll. The school estimates that there are actually 360 students on the A
Sergio [31]

Answer:

Number of 8th Graders = 360 - X

Step-by-step explanation:

As you can see this question is not complete and lacks the essential data. But we will try to create a mathematical expression to calculate the number of students on the A honor roll which are from 8th grade.

As we know:

Total number of students on the A honor roll = 360

We are asked to calculate, number of students from 8th grade on the A honor  roll.

So, let's assume that "X" represents the all the students who are on the A honor roll except 8th grade.

Mathematical Expression:

Number of 8th Graders = Total number of students on the A honor roll - X

Number of 8th Graders = 360 - X

So, if you know the value of X, you can easily calculate the number of students which are from 8th grade on the A honor roll.

Tyler and Bethany have a 240 feet of fencing with which to build a garden Tyler wants the garden to be in the shape of a square
Andrej [43]
If the garden were in the shape of a square, all of its sides would be of equal length. so if you divide 240 by 4 sides, each one would be 60 feet. Then, to find the square garden's area, you multiply 60 x 60 = 360 feet².

If the garden was 50 by 70, you would multiply the two values together to find the area, which is 350 feet².

Because 360 > 350 , Tyler's design would yield the maximum area for a garden
