Answer: 1111

Explanation: As a decimal number can be decomposed in a sum of products involving powers of ten, it can be factored as a sum of products of powers of 2 in order to convert to binary.

In the example, we can write 15 as a decimal number in this way:

1* 10¹ + 5* 10⁰ = 15

Decomposing in powers of 2:

1*2³ + 1* 2² + 1*2¹ + 1.2⁰ = 1 1 1 1 = (15)₂

If you have 10 bits available then you can interpret any number in range [0,2^{10}-1]=[0,1023].

The system therefore could represent the actual temperature of 39°C.

Hope this helps.

Pavlova-9 [17]

Answer:

In Python:

#1

service = input("Enter desired auto service: ")

print("You entered: "+service)

#2

if service.lower() == "oil change":

   print("Cost of oil change: $35")

elif service.lower() == "car wash":

   print("Cost of car wash: $7")

elif service.lower() == "tire rotation":

   print("Cost of tire rotation: $19")

else:

   print("Invalid Service")

Explanation:

First, we prompt the user for the auto service

service = input("Enter desired auto service: ")

Next, we print the service entered

print("You entered: "+service)

Next, we check if the service entered is available (irrespective of the sentence case used for input). If yes, the cost of the service is printed.

This is achieved using the following if conditions

For Oil Change

<em>if service.lower() == "oil change":</em>

<em>    print("Cost of oil change: $35")</em>

For Car wash

<em>elif service.lower() == "car wash":</em>

<em>    print("Cost of car wash: $7")</em>

For Tire rotation

<em>elif service.lower() == "tire rotation":</em>

<em>    print("Cost of tire rotation: $19")</em>

Any service different from the above three, is invalid

<em>else:</em>

<em>    print("Invalid Service")</em>

<em></em>
