iVinArrow [24]

Answer:

purchase_amount = float(input("Enter the amount of a purchase: "))

state_sales_tax = purchase_amount * 0.05

country_sales_tax = purchase_amount * 0.025

print("The amount of the purchase is " + str(purchase_amount))

print("The state sales tax is " + str(state_sales_tax))

print("The county sales tax is " + str(country_sales_tax))

print("The total sales tax is " + str(state_sales_tax + country_sales_tax))

print("The total of the sale is " + str(purchase_amount + state_sales_tax + country_sales_tax))

Explanation:

*The code is in Python.

Ask the user to enter purchase amount

Calculate the state sales tax, multiply purchase amount by 0.05

Calculate the county sales tax, multiply purchase amount by 0.025

Calculate the total sales tax, sum the state sales tax and county sales tax

What two devices in a computer should be considered "black boxes," and should never be opened due to risks involving charged cap

NNADVOKAT [17]

The two devices in a computer that should be considered "black boxes," and should never be opened due to risks involving charged capacitors are MONITOR and POWER SUPPLY.

Explanation:

Physical contact or close proximity to the open power supply caused a discharge from the capacitor that resulted in an electric shock. Capacitors can discharge current even when not energized because they hold a charge for some time after the power is turned off.
To do harm to your body, the voltage across the capacitor's terminals must be high enough to cause a harmful effect on you. There are no hard rules for at what voltage things become harmful, but a common 'rule of thumb' is that DC up to 48 Volt is considered low voltage. So a capacitor charged to a voltage below 48 V is fairly safe.
A charged capacitor can be very dangerous, so it's important that you avoid coming into contact with the terminals at all times.
