Sure! I can help you with the meanings of these math terms.
1. A ratio that compares two quantities measured in different units: This refers to a ratio that compares two different measurements. For example, comparing the height of a person in feet to their weight in pounds.
2. The rate for one unit of a given quantity: This refers to the rate at which a particular quantity changes or occurs. It can be expressed as a rate per unit, such as miles per hour or dollars per hour.
3. Found by multiplying the denominator of one ratio by the numerator of the other ratio: This refers to the cross-multiplication method used to solve a proportion. When you have two ratios set equal to each other, you can find the missing value by multiplying the denominator of one ratio by the numerator of the other ratio.
4. An equation stating that two ratios are equal: This refers to a proportion, which is an equation that shows that two ratios are equal. Proportions are often used to solve problems involving ratios.
5. Figures that have the same shape but not necessarily the same size: This refers to similar figures. Similar figures have the same shape, but their dimensions may be different. They can be scaled up or down, but their angles remain the same.
6. The factor by which each dimension is multiplied in a dilation: This refers to the scale factor of a dilation. In a dilation, each dimension of a figure is multiplied by the scale factor to create the new image. The scale factor determines how much larger or smaller the image will be.
7. A transformation that results in an image that is similar to the pre-image, but larger or smaller: This refers to a dilation. A dilation is a transformation that changes the size of a figure while maintaining the shape. It can make the figure larger or smaller, depending on the scale factor.
8. A dilation of a figure for which the scale factor is greater than 1 and that results in an image that is larger than the pre-image: This refers to an enlargement. An enlargement is a dilation with a scale factor greater than 1, which makes the image larger than the original figure.
9. A figure that is transformed onto an image: This refers to a pre-image. The pre-image is the original figure before any transformation is applied to it. It serves as the basis for comparison with the transformed image.
10. A dilation of a figure for which the scale factor is between 0 and 1 and that results in an image that is smaller than the pre-image: This refers to a reduction. A reduction is a dilation with a scale factor between 0 and 1, which makes the image smaller than the original figure.
11. The ratio that compares a length in a drawing to the corresponding length in the actual object: This refers to the scale of a drawing. The scale is the ratio between the measurements in a drawing and the actual measurements of the object being represented.
12. An enlarged or reduced model of an object that is similar to the actual object: This refers to a scale model. A scale model is a representation of an object that is either larger or smaller than the actual object, but maintains the same proportions and shape. It is often used for demonstration or visualization purposes.
I hope this helps! Good luck with your math quiz!
