owing step to find the length of the unknown leg: Length of the unknown leg = 1572 – 1322 = 24,649 – 17,424 = 7,225 units Which statement best explains whether Lara's step is correct or incorrect? It is correct because the length of the unknown side is the difference of the lengths of the sides. It is correct because the length of the unknown side is the difference of the squares of the sides. It is incorrect because the length of the unknown side is the square root of 42,073. It is incorrect because the length of the unknown side is the square root of 7,225.

A tree in leilas backyard has been growing for 3 1/5 years. It is 3/4 meters tall how many meters per year?
IgorC [24]

Answer:

The tree grew 15/64 meters per year.                  

Step-by-step explanation:

Given

  • Length of a tree = 3/4 meters
  • Total time taken by the tree to grow 3/4 taller = 3 1/5 or 16/5 years

To determine

Per year growth of the tree in meters

Per year growth of the tree in meters can be determined by dividing the total length of a tree i.e. 3/4 meters by the total time taken by the tree to get 3/4 taller.

Per year growth of tree = Total Length  / Total time to grow

                                       = 3/4 ÷ 16/5

                                        = 3/4 × 5/16

                                        = [3×5] / [4×16]

                                        = 15/64 meters

Therefore, the tree grew 15/64 meters per year.
