The approximate mass of Mars is 6.42 X 10^23 kg write this mass and standard notation
Sauron [17]

Answer:

642,000,000,000,000,000,000,000 kg

Step-by-step explanation: Basically you are multiplying 6.42 by 100,000,000,000,000,000,000,000. That looks really intimidating but it is very simple. All you have to do is move the decimal 23 hops to the right. Moving it to the right makes the number big, were moving it to the left makes the number smaller. We want a bigger number because we are writing the number in standard notation. Right now it is in scientific notation form (scientific notation is used because it is easier and quicker to write than writing 21 zeros).

Explain what the equation 110d = 100d + 40 represents<br>in the context of the example problem.​
Tanya [424]

<em>This means that at some specific number of days the cost for Oceanview and  Beachside will be the same.</em>

<h2 /><h2>Explanation:</h2>

See the complete question in the attached file. In this exercise, we know that Oceanview charges $100 per day plus a one-time fee of $40. This can be represented by the following equation:

Total cost for Oceanview:

c=100d+40

Total cost for Beachside:

c=110d

Where:

c:Represents \ the \ cost \\ \\ d:Represents \ the \ number \ of \ day

So we have to explain what the equation:

110d=100d+40

represents in the context of the problem. We have used substitution in order to get that equation, so <em>this means that at some specific number of days the cost for Oceanview and  Beachside will be the same.</em>

This value was calculated and we get that<em> the cost at the hotels will be the same after 4 days and it will be $440.</em>
