Given 3 sides of a triangle, the sum of any 2 sides must be greater than the third side.

Consider the 3 given sides 1, 7 and 11

7 + 11 = 18 > 1

1 + 11 = 12 > 7

1 + 7 < 11 ⇒ not valid

Hence these sides do not form a triangle

A fence builder uses boards 3 1/2 feet long for the vertical slats on the fence. How many slats can be made from a board that is

faust18 [17]

Answer:

12 slats can be made from a board i,e 42 feet long

Step-by-step explanation:

As per the given statement: A fence builder uses boards $3\frac{1}{2}$ feet long for the vertical slats on the fence.

We have to calculate how many slats can be made from a board that is 42 feet long.

Builder uses board $3\frac{1}{2} = \frac{7}{2}$ feet long for the vertical slats.

then;

for 42 feet long = $\frac{42}{\frac{7}{2} } = 42 \times \frac{2}{7} = 6 \times 2 = 12$ slats can be made.

Therefore, 12 slats can be made from a board that is 42 feet long.
