Answer:

The scale factor of the smaller rectangle to the larger rectangle is 3/2

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

In this problem

To find out the scale factor of the smaller rectangle to the larger rectangle. set up a proportion

\frac{9}{6}=\frac{3}{2} ----> ratio of corresponding heights

The histogram shows the numbers of floors in several tall buildings in New york city A.10 B.11 C.41 D.55
scZoUnD [109]

Answer:

10 buildings

Step-by-step explanation:

<em>Incomplete question: Missing Attachment</em>

<em>I will answer your question with the attached histogram</em>

<em></em>

Required

Determine the number of tall buildings that had more than 60 floors

The histogram can be interpreted as follows:

\begin{array}{cccccc}{Floors} & {1-20} & {21-40} & {41-60} & {61-80} \ \\ {Buildings} & {10} & {5} & {15} & {10} \ \end{array}

More than 60 floors is represented with the following group: 61 - 80

The frequency of group 61 - 80 is 10

<em>Hence, 10 buildings had more than 60 floors</em>
