Only C and D are in scientific notation because the decimal has to be after the 3.
Counting how many places you move the decimal to get it behind the 3 we get 8. This is the exponent.

Brian is drawing a scale diagram of a building. for every 10 m of the building he draws a line 5 cm long. Bryn thinks he is usin
ivann1987 [24]

Answer:

200:1, Bryn is correct.

Step-by-step explanation:

Each 10 m is represented by a 5cm length on the diagram.  We first note that 100 cm = 1 meter.   5 cm is (0.5 cm)*(1 meter/100 cm) =0.05 meters.

The 0.05 meters on the diagram represents 10 meters on the actual building.  The ratio is (10 meters/0.05 meters) or 200:1.  This is what Bryn believes is the ratio.

Can someone please answer these 2 questions.
Volgvan

Answer:

The cross section of sphere is circle

Area of cross section = 25 in²

Step-by-step explanation:

From the figure we can see a cylinder with height 8 inches and volume 200 π in³.

<u>The cross section of the cylinder looks like a circle.</u>

<u>To find the area of cross section</u>

Volume of cylinder = Cross section area * Height

200 = cross section area * 8

cross section area = 200/8

 = 25 in²

Area of cross section = 25 in²

<h3>What is the Median of a Data in a Box Plot?</h3>

In a box plot, the median is indicated as the value marked by the vertical line that divides the rectangular box of the box plot.

The median is the middle of the data and represents the 50th percentile. That is 1/2 the data.

In the box plot given, 200 pages is the median. Therefore, the fraction of the books that have 200 or fewer pages is: 1/2.
