Your family had decided to go out to dinner tonight and needs your help calculating the final bill. Your program should accept the prices for 5 meals (prices are decimal numbers). It should also ask for the tax rate (entered as a decimal value). It should print out your total before tax, the amount of tax and the final bill including tax. Once you have all of the values input, calculate the total bill including tax. Tax amounts can have more than 2 decimal places so you need to round your decimal value to the hundredths place and print only 2 decimal values. Example: How much was the first meal? 12.50 How much was the second meal? 11.25 How much was the third meal? 10.90 How much was the fourth meal? 7.95 How much was the fifth meal? 13.85 What is your tax rate? 0.0825 Your bill before tax is $56.45 You owe $4.66 in tax Your bill including tax is $61.11

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.

catya your not at all which answer i've seen you do this on another question!
