Question

1. a tree grows 6 feet per year. which rates are equivalent to 6 feet per year? circle all that apply. a. 2 inches per year b. 18 inches per year c. 12 feet in 4 years d. 72 inches per year e. 2 yards per year

Explanation:

Step1: Convert 6 feet to inches

Since 1 foot = 12 inches, then 6 feet = 6×12 = 72 inches. So 6 feet per year is equivalent to 72 inches per year.

Step2: Convert 6 feet to yards

Since 1 yard = 3 feet, then 6 feet = 6÷3 = 2 yards. So 6 feet per year is equivalent to 2 yards per year.

Step3: Analyze option A

2 inches per year is not equivalent to 72 inches per year.

Step4: Analyze option B

18 inches per year is not equivalent to 72 inches per year.

Step5: Analyze option C

The rate of 12 feet in 4 years is $\frac{12}{4}=3$ feet per year, not 6 feet per year.

Answer:

D. 72 inches per year, E. 2 yards per year
