Answer:
I am guessing about 150 - 200 students did not buy a yearbook.
Step-by-step explanation:
First let's assume that there are 1,000 or so students in the school. 856 would be a little over 4/5 of 1,000 just as 8 would be 4/5 of 10.
Use cross multiplication to should get you the answer...
5/12
Answer:
See below and attached.
Step-by-step explanation:
Draw a rectangle.
Divide it in half.
Divide each part in half again.
Lastly, divide each part again in half.
This will give a total of 8 sections.
Project a uses 1/2 of the fabric. This means it will use 4 out of the 8 pieces.
Project b uses 1/4 of the fabric. This means it will use 2 out of 8 pieces.
So the fabric that is left is 1 - 1/2 - 1/4 = 1/4.
You can find the amount left for any number of yards of fabric by taking f(x) = x/8 - 3/4
Answer:
The equation of the parabolic function is :

Step-by-step explanation:
The standard equation of a parabola is given by:

where
represents the vertex of the parabola.
From the graph shown in figure we can find the vertex of the parabola which is the minimum point of parabola and lies st point 
So, we can say:

Plugging in the values of vertex in standard equation of parabola,

Simplifying the equation:

We can find value of
by plugging in a point from the graph.
Using point (0,-2) which lies on graph.
Plugging in the given point.


Adding 3 to both sides.


∴ 
Plugging in
, the equation of parabola can be written as:
