I used substitution to get to this, but not fully sure if this is correct (solve quadratic)
14, 48, 50
These lengths are double the Pythagorean triple of 7, 24, 25. A triangle with side lengths that are a Pythagorean triple will be right angled.
Answer:
- a) miles per gallon, gallons in tank
Step-by-step explanation:
All the options show functional relationship but the first one
a) miles per gallon, gallons in tank
- There is no direct relationship between these parameters as miles per gallon depends on the speed and the way of driving. This won't be a function when graphed.
b) length of shadows/time of day
- Shadow depends on the time of the day and its length wont repeat at different angles. This is a function.
c) temperature in F, temperature in C
- This is a function as each input will have a unique output.
d) number of employees, number of hours worked
- Hours of work depends on number of employees. This is a functional relationship.
Answer:
m+n=140
Step-by-step explanation:
So the angles in a triangle always add up to 180. We already know that the first angle in the triangle is 40 degrees because it's shown in the angle below the triangle. So we have 140 degrees left since 40 is taken up. That eans m+n=140
