Answer:
3.98 meters
Step-by-step explanation:
First we need to know the formula for finding the height of a cylinder

Now That we know our formula, we just need to put in our numbers and simplify



Answer:
105
Step-by-step explanation:
17.5÷2.5=7
7x15=105
Answer:

Step-by-step explanation:
Given



Required
Determine the number of adults
First, we need to calculate the number of children

Given that: 
Substitute 170 for Girls in 

Convert to fraction

Cross Multiply

Divide both sides by 2



So, the number of children are:



Next, we calculate the number of people in the cinema.

Substitute 765 for Children

Make People the subject.



If 3/5 are children, then 2/5 are adults.
So:




Answer:
1) Jina is not a member of the Music Club.
2) Three students are a member of the Music Club but not the Math Club.
3 Mary and Dan are in all three clubs.
Step-by-step explanation:
Look at the diagram and notice how each club has its own circle. If a student is in that circle, then they are a member of that club. When circles overlap, that overlap space means that a student is a member of two or all three clubs, depending on how many and which circles overlap.
1) Looking at Jina's location on the diagram, she is in the overlap between the math and chess club circles. However, her position does NOT overlap with the Music Club circle, therefore she is not a member of the Music Club.
2) Let's look at the students of the Music Club circle and its overlaps with the Chess Club circle, but NOT the overlaps with the Math Club circle. We can see that Lucy, Josh, and Juan are in these locations, therefore there are three students who are members of the Music Club but not the Math Club.
3) To find which students are in all three clubs, you would look at the middle of the diagram where all three circles overlap. The students listed in this location are Mary and Dan, therefore they are in all three clubs.
Use the calculator to graph the function y = 
In the graph , the coordinates of the vertex is the turning point of the graph.
Given function is the quadratic function. For quadratic function the graph will be U shaped parabola.
There will be only one turning point for parabola
Turning point is the vertex
To find vertex we use formula x= 
y = 
a=2, b= 35
= -6.25
Now plug in
in f(x)

Take common denominator
= -75.125
So coordinates of turning point is (-6.25, -75.13)
The graph is attached below.
