Answer:
La familia de Trevor gastó 86.4 dólares al bañarse en todo el mes.
Step-by-step explanation:
El costo del agua viene dado por:
(1)
Y cada persona de la familia de Trevor gasto en promedio 72 litros de agua. Si la familia tiene 6 integrantes (incluido Trevor) entonces:
(2)
Entonces, toda la familia usó 432 litros de agua en promedio en todo el mes.
Para saber el dinero total gastado por la familia debemos multiplicar la ecuación (1) y la ecuacion (2):
Por lo tanto, la familia de Trevor gastó 86.4 dólares al bañarse en todo el mes.

90/139 is the only fraction not equivalent to 45/70.
To find if a fractions are equivalent, divide the numerator by the denominator for each fraction.
45/70=0.642857
27/42=0.642857
9/14=0.642857
63/98=0.642857
Notice how all of these get you the same number. However, when you divide 90 by 137, you get 0.64748, which is not the same as the others. Therefore, 90/137 is the fraction that is not equivalent to 45/70.
Let
p-------->total paintings that Sergio has in his art collection
step 1
<u>Find the number of paintings that each collectors will donate</u>
Divide the total paintings that the collectors will donate by the number of total collectors
=(48/12)=4 painting
<u>Find the numbers of paintings will sergio have in his art collection after his donation</u>

Answer:
Option B.
Step-by-step explanation:
Inverse function:
Suppose we have a function y = f(x). To find the inverse function, we exchange x and y on the original function, and then isolate y.
The domain of the inverse function(x values) is the range of the original function(y values).
Original function:
Domain is , and when . So the range is , that is,
Inverse function:
Exchanging x and y
The inverse function is
Domain:
Range of the original function is , so the domain of the inverse function is . The correct answer is given by option B.
