Answer: A. Help her distinguish between main topics and subtopics.
Explanation: APEX
Answer:
#here is code in python.
# read the food bill
tot_bill=float(input("Please enter the food bill:"))
# tax on food
tax=0.06
#choice for tip by user
choice=int(input("enter your choice for tip:(1 for 15%, 2 for 18% and 3 for 20% :)"))
// calculate the total food bill
if choice==1:
tot_food_bill=tot_bill+tot_bill*tax+tot_bill*(.15)
elif choice==2:
tot_food_bill=tot_bill+tot_bill*tax+tot_bill*(.18)
elif choice==3:
tot_food_bill=tot_bill+tot_bill*tax+tot_bill*(.2)
else:
print("invalid choice:")
#print the total food bill
print("total food bill is ",tot_food_bill)
Explanation:
Read the food bill from user and assign it to variable "tot_bill".Initialize the tax=0.06 (i.e. 6%) on the bill.Then ask user to give his choice for tip. if the choice is 1 then tip will be 15%, if 2 then 18% and if choice is 3 Then tip will be 20% of the bill.Calculate the total food bill and assign it to variable "tot_food_bill".
Output:
Please enter the food bill:100
enter your choice for tip:(1 for 15%, 2 for 18% and 3 for 20% :)2
total food bill is 124.0
<span>SmartArt can be used to create graphic organizers (Solution:B) that highlight relationships between two items. With SmartArt you can make visual representation of your ideas and information. The tool SmartArt is available </span>in Excel, PowerPoint, Word, but also you create SmartArt object in Outlook.
There are different layouts available for this type of representation.
Domain Name Servers (DNS) are certainly necessary for easy access of resources across a network. The applicable options of the above are A and B - below are explanations as to why.
A: Computers generally are set to automatically obtain DNS information from the network they are connected to or can be pointed to a specific DNS server. This allows for records of where resources (network attach storage devices, other computers on local network, or even website server details) are located on a “master” kind of list so that the local machine’s host file does not have to be routinely updated to contain new addresses.
B: DNS, as explained partially by the answer to A, maintains a type-able or “human readable” domain name for the actual server’s IP address so we don’t have to memorize or keep a list of IPs for where we want to visit on the web (although, Google’s 8.8.8.8 IP address does make it easy). It shows an association between a name/domain name and an IP address so that we can enter something simple (Google.com) and the computer knows where to go (the server at IP address 8.8.8.8) so it can show you the content you want to see.
C: DNS would only simplify remote access if your were attempting LAN (Local Area Network) remote access of another computer on your network. DNS would not make it easier for remote access of a computer on the internet, as most DNS used in non-commercial settings are created and maintained by third-parties that will not put a specific record for one of your computers in it - not that you would want them to either, since it could lead to an open cyber attack.
D: Network throughput is a fancy phrase for network speed. It could be possible that different DNS servers could process requests faster than others, but it is not likely to increase network speed on the whole as navigating via IP or DNS records will be relatively the same speed.
