1)A scale model of a yacht is 15 inches long. The actual length of the yacht is 157.5 feet. How many times as long as the actual yacht is the model?
*i think it is 15/157
2)An artist is making a scale model of a statue she has been commissioned to create.
The model is 2 feet tall. The actual statue will be 15 feet tall.
What is the scale of the model to the actual statue? *i think its 2:15
3)To celebrate the 10th anniversary of the Arthur Ravenel Jr. Bridge, The Post and Courier and the city of Charleston co-hosted an event that included a live build of a 25-foot model of the bridge made entirely of Lego bricks.
If the actual length of the bridge is 13,200 feet, what is the scale factor?
The scale factor of the model to actual bridge is .... ?:?
*i think its 25:13,200
4)While on vacation, Jordan took a photo of a bird. She decided to create a piece of artwork for her home by painting the bird on a 10 x 10 canvas. She measured the image of the bird in the photo at the tallest and longest points and determined it was 2 inches long. If she plans to use a scale factor of 4:13, how long should the bird in the drawing be? *is it 6?
1) To find how many times as long the model is compared to the actual yacht, you need to divide the length of the model by the length of the actual yacht. So, the calculation would be:
Length of model / Length of actual yacht = 15 inches / 157.5 feet
To compare the two lengths properly, you need to convert the length of the actual yacht to inches. Since 1 foot is equal to 12 inches, you would multiply the length of the actual yacht by 12:
(15 inches) / (157.5 feet * 12 inches/foot)
Simplifying this equation, you would get:
(15 inches) / (1890 inches)
And finally, dividing the numerator by the denominator, you would find the answer:
(15 inches) / (1890 inches) = 0.00794
Therefore, the model is approximately 0.00794 times as long as the actual yacht.
2) The scale of the model to the actual statue can be determined by dividing the height of the model by the height of the actual statue. So, the calculation would be:
Height of model / Height of actual statue = 2 feet / 15 feet
Simplifying this equation, you would get:
(2 feet) / (15 feet)
And finally, dividing the numerator by the denominator, you would find the answer:
(2 feet) / (15 feet) = 0.133
Therefore, the scale of the model to the actual statue is 0.133.
3) To find the scale factor of the model to the actual bridge, you need to divide the length of the model by the length of the actual bridge. So, the calculation would be:
Length of model / Length of actual bridge = 25 feet / 13,200 feet
Simplifying this equation, you would get:
(25 feet) / (13,200 feet)
And finally, dividing the numerator by the denominator, you would find the answer:
(25 feet) / (13,200 feet) = 0.0018939
Therefore, the scale factor of the model to the actual bridge is approximately 0.0018939.
4) Using the given scale factor of 4:13, you can determine the length of the bird in the drawing by multiplying the length of the bird in the photo by the scale factor. So, the calculation would be:
Length of bird in drawing = Length of bird in photo * Scale factor
Substituting the given values, you would get:
Length of bird in drawing = 2 inches * (4/13)
Simplifying this equation, you would get:
Length of bird in drawing = 2 inches * 0.3077
And finally, multiplying the two values, you would find the answer:
Length of bird in drawing = 0.6154 inches
Therefore, the bird in the drawing should be approximately 0.6154 inches long.
1) You are correct. The model is 15/157 times as long as the actual yacht.
2) Yes, the scale of the model to the actual statue is 2:15.
3) You are correct. The scale factor of the model to the actual bridge is 25:13,200.
4) To determine the length of the bird in the drawing, multiply the measured length of 2 inches by the scale factor 4/13:
2 inches * (4/13) = 0.615 inches
So, the bird in the drawing should be approximately 0.615 inches long.
1) there are mixed units ... inches and feet ... convert to one or the other and recalculate
2) yes
3) yes ... like a fraction , the answer can be reduced
4) close ... try again ... 4 / 13 = 2 / 6 ??
