A school has eleven Year 9 Maths classes of 27 students. Each class has 4 extra students added to it. Find the total number of students studying Year 9 Maths.
A diving bell is lowered to a depth of -124 metres, i.e 124 metres below sea level. If it rises 38 metres and then drops a further 65 metres from this point what is its new depth?
You really need to try these yourself. Think about what the problem says and do the required calculation. Show your work and someone will help you.
Please do not add second questions to the same post. Start a new one.
-124meters+38meters-65meters= is the process you need to do to get the new depth.
hint on answer = -1_1 find the middle number to get the total depth.
-124 + 38 - 65 = -151, which means 151 meters below sea level
To find the total number of students studying Year 9 Maths, we need to calculate the number of students in each class after the extra students are added, and then add up those numbers.
Given that there are eleven Year 9 Maths classes with 27 students in each class, we can calculate the number of students in each class after the 4 extra students are added.
To do this, we add 4 to the initial number of students in each class:
27 + 4 = 31
So, each class now has 31 students.
Next, we compute the total number of students studying Year 9 Maths by multiplying the number of classes by the number of students in each class:
11 classes × 31 students per class = 341 students
Therefore, the total number of students studying Year 9 Maths is 341.
