Question

If in a bar graph 1 cm represents 30 km, then the length of bar needed to represent 75 km isImmersive Reader (1 Point) a .3.5 cm b. 2.5 cm c. 2 cm d. 3 cm choose from options not from google.

Answer 1

Answer:

b.) 2.5cm

1cm = 30km

therefore 2.5cm = 30*2.5 = 75 Km

Answer 2

Answer:

The answer is (b) 2.5 cm.

Step-by-step explanation:

Given that 1 cm represents 30 km, we can use proportionality to find the length of the bar needed to represent 75 km.

Let x be the length of the bar needed to represent 75 km. Then, we can establish the following ratio:

1 cm / 30 km = x cm / 75 km

Cross-multiplying gives:

30 km * x cm = 1 cm * 75 km

Simplifying further:

x cm = (1 cm * 75 km) / 30 km = 2.5 cm

Therefore, the length of bar needed to represent 75 km is 2.5 cm, which corresponds to a ratio of 1 cm : 30 km in the given bar graph.

Hence, the answer is (b) 2.5 cm.
