some model trains are built 1/87 of actual size. support an actual boxcar is 40 ft long. how many inches long is the model?round your answer to the nearest tenths remeber, there are 12 inches in one foot
To find the length of the model, you need to convert the actual size of the boxcar to inches.
Since there are 12 inches in one foot, the actual boxcar length of 40 ft can be converted to inches by multiplying it by 12:
40 ft * 12 inches/ft = 480 inches
Now, since the model trains are built at 1/87 of the actual size, you can find the length of the model by dividing the actual length by 87:
480 inches / 87 = 5.52 inches.
Rounded to the nearest tenth, the model is approximately 5.5 inches long.
To find the length of the model boxcar, we need to convert the actual length from feet to inches and then multiply it by the scale factor.
Given that the actual boxcar is 40 ft long, we first convert this to inches by multiplying by 12 (since there are 12 inches in one foot):
40 ft * 12 inches/foot = 480 inches
Next, we multiply the actual length in inches by the scale factor of 1/87:
480 inches * 1/87 = 5.5172 inches
Rounding this answer to the nearest tenth, the length of the model boxcar is approximately 5.5 inches.
To find the length of the model train in inches, we need to first convert the 40 ft length of the actual boxcar into inches, and then scale it down by 1/87th.
First, let's convert the 40 ft into inches. Since there are 12 inches in one foot, we can multiply 40 by 12 to get the length of the boxcar in inches:
40 ft * 12 in/ft = 480 inches
Now, let's scale this down by 1/87th. We can do this by dividing the length in inches by 87:
480 inches / 87 = 5.51724137931 inches
Rounding this answer to the nearest tenth, we get:
5.5 inches
Therefore, the model train would be approximately 5.5 inches long.
