the scale used to make a model of a car is 1:18. the length of the model is 91/2 inches. how many feet long is the actual car.
1/18 = 9.5/x
Cross multiply and solve for x,
x = 171 inches
171/12 = 14.25 feet
To find out how many feet long the actual car is, we need to use the scale of 1:18 given in the question.
To understand the scale, we need to know that it represents the ratio between the size of the model and the size of the actual car. In this case, it means that 1 unit on the model is equivalent to 18 units on the actual car.
Now, we are given the length of the model car as 9 1/2 inches. To convert this to feet, we will divide by 12 (since there are 12 inches in a foot).
9 1/2 inches = 9.5 inches
So, the length of the model car in feet is:
9.5 inches / 12 = 0.79 feet (rounded to two decimal places)
To find out the length of the actual car, we multiply the length of the model car by the scale factor.
Actual car length = length of model car * scale factor
Actual car length = 0.79 feet * 18 = 14.22 feet (rounded to two decimal places)
Therefore, the actual car is approximately 14.22 feet long.
To find the length of the actual car, we need to convert the length of the model into the actual length using the scale.
The scale "1:18" means that 1 unit on the model represents 18 units in real life.
First, let's find the length of the model in feet.
Since there are 12 inches in a foot, we can convert the length of the model from inches to feet by dividing by 12:
9 1/2 inches = 9.5 inches = 9.5/12 feet = 0.79167 feet (rounded to 5 decimal places).
Now, we need to scale up the length of the model to the actual length using the scale of 1:18.
To do this, we'll multiply the length of the model in feet (0.79167 feet) by the scale factor (18).
Length of the actual car = Length of the model in feet * Scale factor
Length of the actual car = 0.79167 feet * 18 = 14.25 feet (rounded to 2 decimal places).
Therefore, the actual car is approximately 14.25 feet long.
