o false

question 4 (2 points)
how much does the bar weigh is there is 1 - 25, 1 - 10, and 1 - 2.5 on each side.

o a 125
o b 120
o c 130

Explanation:

Step1: Calculate the total weight of the weights on both sides

On each side, we have weights of 25, 10 and 2.5. The total weight on one - side is $25 + 10+2.5=37.5$. The total weight of the weights on both sides is $2\times37.5 = 75$.

Step2: Assume a standard bar weight

A standard Olympic - style barbell weighs 45 pounds or 20 kilograms. In a more general weight - lifting context, if we assume the bar weighs 45 pounds and we are working in pounds, and we add the weight of the plates on both sides. But if we assume the numbers given are in kilograms and we want to find the total weight of the bar and plates. Let's assume the bar weighs 45 kg. The total weight of the plates on both sides is 75 kg. So the total weight of the bar and plates is $45 + 75=120$ kg.

Answer:

B. 120
