Written numerically, the number you stated is written as:
5,004,300
Standard Form (Scientific Notation) numbers are written as a decimal (n.m) such that there is [normally] only one digit (n) to the left of the decimal point, and the rest of the number (m) to the right (with a possible limit). If there is only a single digit in the whole number then the value on the right is a zero (n.0).
To show that the value shown has shifted its decimal point position, the number of decimal positions shifted is shown after the number as a 10’s multiplied to the power of the number of positions shifted.
e.g., 102 = 102.0 = 1.02 (decimal point shifted left two places. If smallest digit is 0 then ignore it UNLESS it’s the ONLY digit!!)
1.02*10^2(2 Decimal shift to the left)
1.02*10^2
So, for the number asked in the question:
5,004,300 = 5,004,300.0
Left shift 6 times to largest digit = 5.004300
5.004300 (show the shift multiplier: 10^6)
5.004300*10^6
Since he bought more than one of each, he needs to find the total cost of the biscuits and sausage first.
The correct answer should be:
<span>B. Step 1: Calculate the price of 3 biscuits. Step 2: Calculate the price of 3 sausages. Step 3: Add the total amounts from Steps 1 and 2 to the amount of the tip. Step 4: Subtract that total amount from $25.</span>
3 cm on the map represents 31.5 km in reality.
3cm : 31.5 km
1cm : 31.5/3 km
1cm : 10.5km
So the scale on the map is 1cm represents 10.5 km.
The answer would be $2.70
