A Rectangular table seats four people on one side and two people on each end. How many seats are available if the ends of five t
ables are placed together?
1 answer:
Answer:
44 seats.
Step-by-step explanation:
Ends of 5 tables are placed together. When this is done, there are only 2 ends, one on each side of the 5 tables as shown in the image below. All the other ends are blocked when tables are joined together.
Since, 2 people can sit on each end, 4 people can sit on two ends of the tables.
For one table there are 2 sides and on each side 4 people can be seated. No sides are blocked, so all the sides of 5 tables are open.
Total number of sides of 5 tables = 10
Number of people on each side = 4
So, total number of people on 10 sides would be = 40
Hence, total seats that would be available = Seats on ends + Seats on sides = 4 +40 = 44
44 seats are available if the end of 5 tables are placed together.

Step-by-step explanation:
The conversion factor in the box is the product ...
_____
The purpose of a conversion factor is to multiply by 1 in the form of a ratio that changes the units. We know that 1000 Pa = 1 kPa, so the ratio (1 kPa)/(1000 Pa) is the ratio of two equal quantities. It has the value 1 and will change units from Pa to kPa.
Likewise, 100 cm = 1 m, so (1 m)/(100 cm) will change the units from cm to m. However the given expression uses cm³, so we need to multiply by the conversion factor 3 times. That factor is ((1 m)/(100 cm))³ = (1 m³)/(10⁶ cm³).
To choose the appropriate conversion factor, look at the units you have (Pa, cm) and the units you want (kPa, m). Find the relationship these have to each other, and write the ratio so that it will cancel the units you have and leave the units you want.
When SI units are involved the prefixes help you out. k = kilo = 1000; c = centi = 1/100. It is worthwhile to get to know them.
