Answer:
- notice: temperature rises quickly at sunrise, and drops before sunset
- wonder: whether this location is shaded by mountains later in the day
Step-by-step explanation:
<u>notice</u>
The temperature starts off below zero in the early morning and stays cold until the sun comes up. Then it warms rapidly to an above zero temperature that peaks in early afternoon. Once the sun gets lower, the temperature starts cooling off again. (The daily temperature range of 25-27 degrees is pretty typical for partly-cloudy sky conditions and stable weather.)
<u>wonder</u>
We wonder if this isn't a location that is on the east- or north-side of a mountain, or in a mountain valley, where the sun hits it early and is shaded later in the day. (The topo map attached seems to show it is in such a location.)
Answer:
2^5
Step-by-step explanation:
Keep dividing by primes until you can't anymore. The numbers you divided by are the prime factors. The only one you need is 2.
32 = 2·16 = 2·2·8 = 2·2·2·4 = 2·2·2·2·2
32 = 2^5
Answer:
He would gain by choosing air travel if, and only if, he values his time at more than $5 per hour.
Step-by-step explanation:
The problem states that:
A bus ticket from Washington to St. Louis costs $100, while it takes 32 hours to arrive.
A plane ticket from Washington to St. Louis costs $250, while it takes 2 hours to arrive.
Other things constant, Andrew would gain by choosing air travel if, and only if, he values his time at more than
If Andrew choses to go by plane, he saves 32-2 = 30 hours at the expense of $250-$100 = $150.
So, dividing the extra cost by the number of hours saved:

He would gain by choosing air travel if, and only if, he values his time at more than $5 per hour.
