the first parallelogram
3.5in. 5in.
the seconded parallelogram
0.7in. 1in.
Kamla draws the first parallelogram and then uses a scale factor to create the seconded parallelogram. All measurements are in inches. What scale factor does he use
To find the scale factor that Kamla used, we need to divide the corresponding side lengths of the second parallelogram by the corresponding side lengths of the first parallelogram:
Scale factor = (corresponding side length of second parallelogram) / (corresponding side length of first parallelogram)
Using the given measurements:
Scale factor = (0.7in. / 3.5in.) / (1in. / 5in.)
Scale factor = (0.2) / (0.2)
Scale factor = 1
Therefore, Kamla used a scale factor of 1.
To find the scale factor used by Kamla, we will compare the corresponding sides of the two parallelograms.
For the first parallelogram:
Side A = 3.5 inches
Side B = 5 inches
For the second parallelogram:
Side A = 0.7 inches
Side B = 1 inch
To find the scale factor, we divide the corresponding sides of the two parallelograms.
Scale factor for Side A = Side A of Parallelogram 2 / Side A of Parallelogram 1
Scale factor for Side A = 0.7 inches / 3.5 inches
Scale factor for Side A = 0.2
Scale factor for Side B = Side B of Parallelogram 2 / Side B of Parallelogram 1
Scale factor for Side B = 1 inch / 5 inches
Scale factor for Side B = 0.2
Therefore, Kamla used a scale factor of 0.2 to create the second parallelogram.
To determine the scale factor used to create the second parallelogram, we can compare the corresponding side lengths of the two parallelograms.
From the given information, the first parallelogram has side lengths of 3.5 inches and 5 inches. Let's call these lengths a and b, respectively.
The second parallelogram has side lengths of 0.7 inches and 1 inch. Let's call these lengths x and y, respectively.
The scale factor (k) relates the corresponding side lengths of the two parallelograms. We can express this relationship as:
x = k * a
y = k * b
To find the value of k, we divide the corresponding side lengths from the second parallelogram by the corresponding side lengths from the first parallelogram:
k = x / a
k = y / b
So, to find the scale factor used by Kamla, we divide the side lengths of the second parallelogram by the side lengths of the first parallelogram:
k = 0.7 / 3.5
k = 1 / 5
Therefore, the scale factor used by Kamla to create the second parallelogram is 0.2.
wrong
Apologies for the incorrect response.
To find the scale factor used by Kamla, we divide the corresponding side lengths of the second parallelogram by the corresponding side lengths of the first parallelogram:
For side A: (0.7in / 3.5in) = 0.2
For side B: (1in / 5in) = 0.2
Therefore, Kamla used a scale factor of 0.2 to create the second parallelogram.
Ana Maria needs to convert this scale drawing from a scale of 1 box = 4 inches to a scale of 1 box = 2 inches. The width in the scale drawing shown is 3 boxes. What will be the width in boxes of the new drawing
To convert the scale drawing from a scale of 1 box = 4 inches to a scale of 1 box = 2 inches, we need to reduce the size of the boxes.
Since the original drawing has a width of 3 boxes, the new width in boxes can be calculated as follows:
New width in boxes = (Original width in boxes) * (New scale / Original scale)
New width in boxes = 3 boxes * (2 inches / 4 inches) = 3 * (1/2) = 1.5 boxes
Therefore, the width in boxes of the new drawing will be 1.5 boxes.
Teresa estimates that the height of a giraffe in a zoo is 18 feet. In fact, it is 16 feet tall. What is Teresa’s percent error? Use proportional relationships to solve the problem
To find Teresa's percent error, we can use the formula:
Percent Error = (|Measured Value - Actual Value| / Actual Value) * 100
In this case, the measured value (estimated height) is 18 feet, and the actual value (height of the giraffe) is 16 feet.
Percent Error = (|18 - 16| / 16) * 100
Percent Error = (2 / 16) * 100
Percent Error = 0.125 * 100
Percent Error = 12.5
Therefore, Teresa's percent error is 12.5%.
