The exact value of 400 comma 000 times 200 is 8. (use scientific notation. use the multiplication symbol in the math palette as needed.)

The scientific notation of 8,000,000 is 8 × 10^6

Step-by-step explanation:

* Lets explain the meaning of the scientific notation

- Scientific notation is a way of writing very large or very small numbers

- A number is written in scientific notation when a number between 1

 and 10 is multiplied by a power of 10

- Ex:  650,000,000 can be written in scientific notation as

        6.5 × 10^8

- We put a decimal points to make the number between 1 and 10 and

 then count how many places from right to left until the decimal point

 The decimal point between 6 and 5 to make the number 6.5 and

 there are 8 places from the last zero to the decimal point

* Lets solve the problem

∵ The exact value of 400,000 × 200 = 8,000,000

- Put the decimal point before 8 and count how many places from

 the last zero to the decimal point

∵ There are six places from last zero to the decimal point

∴ The scientific notation of 8,000,000 is 8 × 10^6

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
