Divide 9.60 by 3, and 15.75 by 4.50
The bigger number will be the most expensive and subtract the bigger quotient by the smaller and you’ll get the difference.

The graph of a proportional relationship passes through (12, 16)<br> and (1, y)<br> . Find y
k0ka [10]

Answer: The value of y is \frac{4}{3}.

Explanation:

It is given that the graph of a proportional relationship passes through (12, 16)

and (1, y).

The graph of a proportional relationship means the x and y coordinates are in a proportion k. The equation of the graph is in the form of y=kx. Where k is the proportion factor.

It is given that the graph passing through (12,16).

y=kx

16=k(12)

k=\frac{16}{12}

k =\frac{4}{3}

So the equation of the line is,

y=\frac{4}{3} x

put x=1.

y=\frac{4}{3} (1)

y=\frac{4}{3}

Therefore, the value of y is \frac{4}{3}.

AMC 10/12 Student Practice Questions
a_sh-v [17]

Answer:

\mathrm{C.\:}25

Step-by-step explanation:

Notice how each congruent square is divided into four equal parts. Since each square has four parts and there are four squares, there are 16 of these parts in total. Because each of these parts make up \frac{1}{4} of each square, all parts are equal. Therefore, you can count the total number of shaded parts to get your percentage.

The top left and bottom right both have one part shaded each for a total of 2 parts.

The top right and bottom left have 0.5 and 1.5 parts shaded, respectively, for a total of 2 parts.

Therefore, in total, there are 2+2=4 parts shaded out of 16 total parts.

Thus, the percentage of the total area that is shaded is:

\frac{4}{16}=\frac{1}{4}=\fbox{$25\%$}.
