Answer:
A
Step-by-step explanation:
If the variable quantities are the same, but the constants are different, then that equation has no solutions.
A) 3:11
b) 11:8
this should be correct
Answer:
n = 9
Step-by-step explanation:
Create equivalent expressions in the equation that all have equal bases, then solve for n.
3 x 3 = 9
Therefore, n = 9
Hope this helps! :D
To find the slope in the graph you need to find two perfect points on the line then count how many times you went up which is the y over how many times you go right which is the x its called the rise/run. To find the slope in the equation use the formula y2-y1/x2-x1.
Answer:
El pH del refresco es 3.42.
Step-by-step explanation:
Se puede calcular el pH del refresco usando la siguiente fórmula:
![pH = -log([H^{+}])](https://tex.z-dn.net/?f=pH%20%3D%20-log%28%5BH%5E%7B%2B%7D%5D%29)
En donde:
[H⁺]: es la cocentración de los iones H⁺ de la solución
Entonces, el pH es:
![pH = -log([H^{+}]) = -log(3.8\cdot 10^{-4}) = 3.42](https://tex.z-dn.net/?f=pH%20%3D%20-log%28%5BH%5E%7B%2B%7D%5D%29%20%3D%20-log%283.8%5Ccdot%2010%5E%7B-4%7D%29%20%3D%203.42)
El resutlado obtenido nos permite concluir que ese refresco es ácido.
Por lo tanto, el pH del refresco es 3.42.
