4. How many steel rods are in a truss 50 feet long overall? Explain how to find this number without drawing the truss.

199 steel rods

Step-by-step explanation:

From that attached diagram, we are told that a truss is made by attaching 1 foot long steel rods together.

In order to make an additional length for the Truss, we use this algebraic expression formula:

Number of steel rods = 4x - 1

Where x = Number of feet

Where x = 1 feet

4(1) - 1 = 4 - 1 = 3 steel rods

From the above question, we are asked to determine number of steel rods in a 50 feet long truss.

Applying the Formula

4x - 1 = Number of steel rods

4(50) - 1

200 - 1 = 199 steel rods.

Therefore, 199 steel rods are in a truss 50 feet long overall

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.
