A right angle triangle will follow Pythagorean theory where a^2(hypotenuse)= b^2+ c^2
Therefore 17^2=11^2+ c^2
289=121 + c^2
168 = c^2
c= 13 rounded to the nearest tenth
We have to write a proportion. We put 35 over 60 to show that 35 miles can go in every 60 minutes. Next to it we write another fraction and put 490 over x because we are trying to find how many MINUTES first. we multiply 490 by 60 which is 29400. Now we divide that by 35. we get 840 minutes. Now we convert this into hours by dividing it by 60 because there are 60 minutes in an hour. 840 divided by 60 is 14 hours. The answer is 14 hours.

Answer:
x = 20
Step-by-step explanation:
We can define z = 3^(x/10). Then the equation is quadratic, which we can solve by completing the square. X can be found from the positive solution for z.
The answer is 29.4 grams.
How to solve:
1. Convert $15 to quarters. You can do this by multiplying 15 by 4. You use 4 because 4 quarters equal to $1. This will equal to 60 quarters.
2. Multiply both 5.76 and 6.25 by 60 to find the weight of $15 in quarters for today and before 1965.
Today: 5.76 g x 60 = 345.6 grams
Before 1965: 6.25 g x 60 = 375 grams
3. Now that you have the weight of quarters for both time periods, subtract! 375 grams - 345.6 grams = 29.4 grams
