Mr Lee has a board that is 6.45 feet long . He wants to cut it into three equal pieces . How long should each piece be

Each board should be 2.15 ft long

Step-by-step explanation:

6.45 ft ÷ 3 boards = 2.15 ft for each board

2.15 feet

Step-by-step explanation:

Since he wants 3 equal pieces, you need to divide the total amount (6.45 feet) by three.

6.45/3 = 2.15 feet

1.24 m

Step-by-step explanation:

F ∝ 1/d²

F = k/d²

Use values given to solve for k

0.006 = k/3²

k  = 0.054 (I multiplied both sides by 3² in the equation above)

New equation is F= 0.054/d²

Plug in your numbers so 0.035 = 0.054/d²

0.054/0.035 = d²

You can simplify if you want so d² = 54/35

Square root both sides to solve for d

√54/35 = 1.24 m
