The length and width of a certain rectangle are both decreased by 50%. If the length and width of the new rectangle are then inc

51% less.

The length is decreased by 50%, which is the same as being multiplied by 0.5, then it's increased by 40% which is another multiplication by 1.4. So the overall change is 0.5 * 1.4 = 0.7, or the newest rectangle is 70% of the size of the original rectangle. And since the area increases by the square, the newest rectangle has 0.7 * 0.7 = 0.49 of the area as the original rectangle. So it has 51% less area than the original rectangle.

Which type of graph would allow us to compare the median number of teeth for mammals and reptiles easily
kirill [66]

Solution:

A bar graph or Double bar graph would be most suitable representation to compare the median number of teeth for mammals and reptiles.

Keep in mind: Median of a data set is mid value , if arranged in ascending or descending order.

Explanation:

Suppose a group of mammals,according to their weight is considered for study and their teeth are counted and median number of teeth of data set are calculated.

Similarly, for a group of reptiles which underwent for study for their number of teeth, and then median value of all reptiles which possess teeth is calculated.

So, best way to compare their number of teeth of mammals and reptiles is Draw the bar graph of each data set of mammals, and then also draw the bar graph of each reptile and then calculate the median value of mammal and reptile and then you can draw the graph separately for median values of both and then compare.

You can compare the medians of the two data set of Reptiles and Mammals by Double bar graph also.

Set this up as ratio with feet on top and minutes on the bottom: \frac{14}{213}= \frac{x}{8}.  Cross multiply to get 213x = 112 and solve for x to get x = .52 feet.  This means that after she has been descending for 8 minutes she is a half a foot from the top.
