A rational number<span> is a </span>number<span> that </span>can be written<span> as a </span>ratio<span>. That means it </span>can be written<span> as a fraction, in which both the numerator (the </span>number<span> on top) and the denominator (the </span>number<span> on the bottom) are whole </span>numbers<span>. The </span>number<span> 8 is </span>a rational number<span> because it </span>can be written<span> as the fraction 8/</span>1<span>.</span>
First lets convert feet to miles: if 1 mi = 5280 feet then 7200 feet / 5280 feet = 1.364 miles. Now we need to see how much degrees does the boiling point for water decreases: if 1 mile = 5 degrees Celsius, then 0.364 miles correspond to 0.364*5=1.82 degrees Celsius. So now we add the two values: 5+1.82 = 6.82 degrees Celsius. Now we find the decrease in the boiling point of water: 100-6.82 = 93.18 degrees Celsius. So at 7200 feet above sea level, in Santa Fe, the water boils at 93.18 degrees Celsius.
Answer:
6 $10 bills
Step-by-step explanation:
First you have to make a system of equations like such
5x + 10y = 150
x + y = 24
Now you can use any strategy to simplify it but I'll use multiplication and the subtraction:
5x + 10y = 150 - 5x + 5y = 120 = 5y = 30 this simplified is y = 6. You then substitute 6 for y in either equation. x + 6 = 24 and make it on opposite sides. x = 18.
So 18 $5 bills and 6 $10 bills
I'm not sure I'm understanding the wording of the question, but if it's this:
Juice boxes come in a package with multiple juice boxes in each package. Three people bought 18, 36, and 45 juice boxes. What is the largest possible number of juice boxes per package?
Then the problem is just an involved way of asking what the greatest common factor of 18, 36, and 45 is, and the answer is 9, the difference between 36 and 45, which are both multiples of 9. Note that 18 is also a multiple of 9. One way to find the greatest common factor of three numbers is to factor all of them and find which prime factors they have in common.
Fran will have a base amount of $800 saved at the end of the 20 weeks assuming she continues to get at least 15 hours and her expenses don't increase (40x20 =800). At a net pay rate of $15 per hour (225/15=15), she will need to work an additional two hours per week for a total of 17 hours to earn the $600 needed to meet her goal. [15x2= 30, 30x20=600]
