Jamie can read at a speed of 65 pages per hour. If she reads a novel that has 400 pages, how long will it
horsena [70]
To find the answer set up an equation:
400 \: pages \times  \frac{1 \: hour}{65 \: pages}  =
Using this set up we can cross our units of pages since they are on opposite side of the proportion, leaving us with the desired units of hours.

Then divide 400 by 65 which will give us our answer: 6.15 or about 6 hours for Jamie to finish her reading.

A number cube is rolled what is the probability that the result is a number greater than five?
ki77a [65]

Answer:

The answer is 1/3

Step-by-step explanation:

Let the events of getting the no. greater than 4 be (>4).

Then,

<em>n</em><em>(</em><em>s</em><em>)</em><em> </em><em>=</em><em> </em><em>6</em>

<em>n</em><em>(</em><em>></em><em>4</em><em>)</em><em> </em><em>=</em><em> </em><em>2</em>

<em>P</em><em>(</em><em>></em><em>4</em><em>)</em><em> </em><em>=</em><em> </em><em>n</em><em>(</em><em>></em><em>4</em><em>)</em><em>/</em><em>n</em><em>(</em><em>s</em><em>)</em>

<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>=</em><em>2</em><em>/</em><em>6</em>

<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>=</em><em>1</em><em>/</em><em>3</em>

Which of the following are congruence transformations? A.Shrinking B.Rotating C.Reflecting D.Stretching E.Translating
Soloha48 [4]
<u><em>Answers:</em></u>
Rotating
Reflecting
Translating

<u><em>Explanation:</em></u>
Congruence transformation is a transformation that does not change neither the side lengths nor the measures of the angles.
This means that the formed image is an exact copy of the original figure

<u>Now, let's check the options:</u>
<u>1- Shrinking:</u> This means that we are decreasing the side lengths. 
This option is incorrect

<u>2- Rotating:</u> This means that we are just changing the orientation of the figure without altering any measurements.
This option is correct

<u>3- Reflecting:</u> This means that we are just changing the orientation of the figure without altering any measurements.
This option is correct

<u>4- Stretching:</u> This means that we are increasing the side lengths. 
This option is incorrect

<u>5- Translating:</u> This means that we are just changing the position of the figure without altering any measurements.
This option is correct

Hope this helps :)
