Answer:

Round up all costs

Least expensive: $6

Most expensive: $13

Other half

$60 + 60=$120 best estimate $125

How much is the number 727731000 in percent form
tankabanditka [31]

Answer:

72773100000%

Step-by-step explanation:

"Percent" means "per 100" or "over 100". So, to convert 727731000 to percent we rewrite 727731000 in terms of "per 100" or over 100.

Multiply 727731000 by 100/100. Since 100/100 = 1, we are only multiplying by 1 and not changing the value of our number.

7277310001×100100=72773100000100

72773100000/100 is 72773100000 over 100 and means 72773100000 per 100. 72773100000 "per 100" means 72773100000 "percent" or 72773100000%

Therefore, we have shown that

727731000 = 72773100000%

Simplified Conversion:

Multiply by 100 and add the percent sign %

727731000 × 100 becomes 72773100000%

Shortcut Conversion:

Move the decimal point 2 places to the right and add the percent sign %

727731000 becomes 72773100000%

Ronch [10]

<u>Answer:</u>

The correct answer option is 'then'.

<u>Step-by-step explanation:</u>

For example, we have this problem:

y = 2 x - 1

If x = 3, then find the value of y.

Here in this problem, we are asked that 'if' the value of x is true then prove it by substituting in the value.
