Answer:
1 7/10
Step-by-step explanation:
First, you would convert the first mixed number into an improper fraction. In this case, it would be 17/4.
The next step would be to multiply the two fractions. To re elaborate, we would be multiplying 17/4 * 2/5. If you don't know how to do that, ask me.
The product is 34/20. It says to simplify the answer into a mixed number, so that would be 1 14/20, simplified to 1 7/10.
Hope this helps! :)
Answer:
<h2>91</h2>
Step-by-step explanation:
Find the volume of the prism shown. The formula for the volume of a prism is V=Bh , where B is the base area and h is the height. The base of the prism is a rectangle. The length of the rectangle is 13 cm and the width is 7 cm.
A. 1800 degrees.
The sum of all the interior angles is 1800 degrees.
In any polygon the exterior angles all add up to 360 degrees.
So it is 1800.
B. 150 degrees,
The interior angles are 150 degrees.
The exterior angles are 30 degrees,
Hence 30•12=360, 150•12=1800.
C. No, not without the use of other regular polygons to fill the gaps in between. So, you can use it to tile a flat surface, but there will be gaps and voids to fill with other tile. Or if you want to get technical, for you tile the plane by congruent regular polygons, there must be polygons meeting at each vertex. Thus the interior angles of each polygon must be 2/, for some positive integer . The vertices always come together at some point. That is, with rectangular tiles there are always groups of 4 tiles, and the 4 corners are 90 degrees each so 4 of them add up to 360. A hexagon has an interior angle measure of 120, and 120 is the greatest factor of 360 (other than 180, which is a straight line, or 360). If you have polygons with 7 or more sides, their corners will not fit nicely to add up to 360 degrees:)
