Express your answer in simplest form.
2 1/12. It took her 2 hours and 5 minutes or 2 1/12.
One cubic foot of sand weighs 100 pounds a square sandbox with 5 foot sides has half a foot of sand in it how many pounds of sand in the sandbox holding
about 250 lbs because its half a foot deep of sand then you split the sum of the measurement in half
H(x) = x3 + 7 Determine whether the function is one-to-one.
we conclude that the function is one-to-one.
A function will a one-to-one function if it
passes the vertical line test to make sure it is indeed a function, and
also a horizontal line test to make sure it is it one-to-one.
In other words,
The function will be one-to-one if it passes the vertical line test, and also if the horizontal line only cuts the graph of the function in one place.
The reason is that there must be only one x-value for each y-value.
Given the function
Have a look at the attached graph.
The red portion represents the graph of the function .
The green portion represents the graph of x=2 which is basically a vertical line test. Vertical line indicates that it cuts the cuts the graph of the function in one place. So it is clear that is indeed a function.
The blue line represents the graph of y=9, which is basically a horizontal line test. Horizontal line indicates that it cuts the cuts the graph of the function in one place. So it is clear that is a one-to-one function, as there is only one x-value for each y-value.
Therefore, we conclude that the function is one-to-one.

It costs $95 for 20 students to visit an aquarium. How much does it cost for 162 students?
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:
