If you gave away 280 of 600 business cards and you would like to know what percent of the cards is left, you can calculate this using the following steps:
600 - 280 = 320 cards are left
320 / 600 = 8 / 15 = 0.5333 = 53.33%
The correct result is D. 53.33%.
Adding them up, we have 1/2+3/20+2/5+4/5. We can do a bit of guess and checking to see that 2, 5, and 20 go into 20. 20/2=10 and 20/5=4, so we multiply 1/2 by 10/10 and 2/5 and 4/5 by 4/4 to get 10/20+3/20+8/20+16/20= 37/20
formula for polyhedrons is V-E+F=2
F= faces = unknown F
V= vertices=F-8
E= edges=30
(F-8)-30+F=2
add the 2 F's and 30 & 8 so you get 2F-38=2
ince -38 doesn't have variable move it to other side by adding 38 to both sides
2F=38+2 which becomes 2F=40
now divide both sides by 2 to get F=20 so there are 20 faces

Answer:
e. A census, because the wholesale prices of all items are listed.
Step-by-step explanation:
A census encompasses collecting data of an entire population as well evaluation of the characteristics of an entire population. Every item currently in store alongside their wholesale price was included in the survey here. None was excluded. So we cannot call the activity a sample survey. Since all items were counted, the best description to give to this activity is "a census".
