Not sure what the question is asking, but what you listed is true. Percentage is out of 100 and the denominator would always be 100.
Answer:
Step-by-step explanation:
Find the diagram to the question attached.
The standard equation of a line in point-slope form is expressed as:
where:
m is the slope of the line
is coordinate point on the line
First is to get the slope of the line.
If after buying 2 lattes, she has $2 left, hence one of the coordinate of the line is (2, 2). We can get the other coordinates from the graph. From the graph, it can be seen that when x = 0, y = 8. Hence the other coordinates is (0, 8)
Hence the slope is -3
Substitute m = -3 and the point (2, 2) into the formula to get the required equation (note that any of the points can be used)
Hence the equation of the line in point-slope form is
<u>EXPLANATION</u>
The reason is that
If we multiply by its conjugate
We obtain;
This is difference of two squares so we obtain;
This further gives us,
Since the , we substite to get;
The is now eliminated and we get,
Answer:
24% can be written as 0.24 which is 24 / 100 or 6/25.
The formula for surface area is SA = 2 (wl + hl + hw). Plugging in the numbers that we know, we get SA = 2 (100 + 10h +10h). We know that the crust accounts for half of the surface area.
The surface area was not provided so this is the closest I can go without the provided surface area. I hope this helps you :)
