Question

1. neoma is playing with 3d modeling software to design a perfect couch for her apartment. the first model was only 1 inch long on her screen, so she changed the zoom so that the model was 2.9 inches long. by what factor did she change the scale?
2. if an object was 3.1 cm at a 50 ft scale, what size is it at a 175 ft scale?

Explanation:

Step1: Determine the scale factor for problem 5

The scale factor is calculated by dividing the new length by the original length.
$$\text{Scale Factor}=\frac{2.9}{1}$$

Step2: Calculate the size for problem 6

First, find the scale factor from \(50\) ft to \(175\) ft: $\frac{175}{50} = 3.5$. Then multiply the original size (\(3.1\) cm) by this scale factor.
$$\text{New Size}=3.1\times3.5$$

Answer:

For problem 5: \(2.9\). For problem 6: \(10.85\) cm.
