Answer:
-2
Step-by-step explanation:
slope is rise over run
-2/1
= -2
At the considered rate the fraction of pool that is filled per hour is 13/12
<h3>How to measure the rate of change of something as some other value changes?</h3>
Suppose that we have to measure the rate of change of y as x changes, then we have:

where we have

Remember that, we divide by the change in independent variable so that we get some idea of how much the dependent quantity changes as we change the independent quantity by 1 unit.
(5 change per 3 unit can be rewritten as 5/3 change per 1 unit)
For the considered case, we can take time spent as difference of independent variable, and the amount of pools filled as the corresponding difference of the dependent variable.
in 12 hour time interval total 13 pools were filled.
That means
Rate of filling the pool is 13 pools per 12 hours or
pools per hour.
Thus, at the considered rate the fraction of pool that is filled per hour is 13/12

Answer:
82.5°
Step-by-step explanation:
This is the case of a isosceles triangle , as you may know in a isosceles triangle , there are two sides of equal length as well as two equal angles.
You know that the sum of angles in a triangle is 180°, therefore it comes to this equation :
15° + 2x = 180°
2x = 165°
x = 82.5°
therefore 82.5° is the correct answer.
Answer:
La base salarial de cada trabajador es de $ 425
Step-by-step explanation:
Aquí queremos calcular la base salarial de cada trabajador
Antes del incremento, sea la base salarial $ x
Entonces, sin el incremento, lo que ganarán los 3 es x + x + x = 3x
Con el incremento, cada uno ganará 3 (x + 50)
Esto es lo que es igual a 1425 Así; 3 (x + 50) = 1425
x + 50 = 1425/3
x + 50 = 475
x = 475 - 50
x = 425
