It costs $95 for 20 students to visit an aquarium. How much does it cost for 162 students?
Answers
Answer 1
Answer:
Set up a proportion:
Now cross multiply:
Set it up as an equation:
Divide both sides by 20:
And you get:
x=769.5
But you cannot have a half of a student so you will round it up:
x=770 students.
Now cross multiply:
Set it up as an equation:
Divide both sides by 20:
And you get:
x=769.5
But you cannot have a half of a student so you will round it up:
x=770 students.
Answer 2
Answer:
162 students* ($95/ 20 students)= $769.50
The final answer is $769.50~
The final answer is $769.50~

prime factors of 42: 2x7x3
prime factors of 126: 2x3x3x7
prime factors of 210: 7x3x5x2
now we multiply all the factors that they all have in common: 2x3x7 which is 42. So the highest common factor is 42

Since the "base of a triangular sail is 5m shorter than its height", we have the equality
Start with the formula for the area of a triangle
Plug in , , and
Multiply both sides by 2
Distribute
Subtract 36 from both sides
Factor the right side (note: if you need help with factoring, check out this solver)
Now set each factor equal to zero:
or
or Now solve for x in each case
So our possible answers are
or
However, since a negative height doesn't make sense, our only solution is
So the height is 9 m
Now subtract 5 from the height to get the base
So the base is 4 m
Check:
Start with the formula for the area of a triangle
Plug in , , and
Multiply
Divide. Since the two sides of the equation are equal, this verifies our answer.

If you have a triangle with a base of 5m and an area of 20m2, to find the height begin with the formula of the area of a triangle.
A=1/2bh
Then, plug in your known numbers
20m2=1/2h(5m)
What I do next, is I work backwards by dividing the are by 1/2, which equals 40. All that is left to do, is divide this number, 40, by 5 to find the height.
40/5=8
Therefore, the height of the triangle is 8m
A=1/2bh
Then, plug in your known numbers
20m2=1/2h(5m)
What I do next, is I work backwards by dividing the are by 1/2, which equals 40. All that is left to do, is divide this number, 40, by 5 to find the height.
40/5=8
Therefore, the height of the triangle is 8m
