Use the table above that shows information about squares.

Are the perimeter and the side length of squares proportional? Explain.

• No, the ratios $\frac{perimeter}{side\ length}$ for the squares are equivalent, so they are proportional.

• Yes, the ratios $\frac{perimeter}{side\ length}$ for the squares are equivalent, so they are not proportional.

• No, the ratios $\frac{perimeter}{side\ length}$ for the squares are not equivalent, so they are not proportional.

• Yes, the ratios $\frac{perimeter}{side\ length}$ for the squares are equivalent, so they are proportional.

Write and solve a proportion to find the perimeter of a square when its side length is 12.

• $\frac{ }{1}=\frac{4}{12};\ p\ =48$

• $\frac{4}{1}=\frac{ }{12};\ p\ =48$

• $\frac{4}{1}=\frac{12}{ };\ p=48$

• $\frac{4}{ }=\frac{1}{12};\ p\ =48$

Sally is going on vacation with her family. In 2 hours they travel 90.5 miles. If they travel at the same speed, write an equation that represents how far they will travel, d, in h hours.

• d = $\frac{4}{181}$ h

• d = 45h

• d= $\frac{181}{4}$ h

• d = $\frac{1}{45}$ h

The table shows the weights of bunches of bananas and the price of each bunch. Identify the constant of proportionality. Write an equation to relate weight, w, to the price, p.

• k = 1.26; k = 1.26w

• k =3.8; k = 3.8w

• k = $\frac{20}{9}$ ; k = $\frac{20}{9}$ w

• k = 0.45; k = 0.45w
