Answer:
B
Step-by-step explanation:
The profit made is equal to 2.25-2.25 which is 0.
Applying the percentages, and considering that 70% of the first group drinks at least 2 glasses of water a day, it is found that 0.725 = 72.5% of the team drinks at least 2 glasses of water a day.
The team is divided into two equal groups, hence, each represents 50%.
The <em>percentages </em>associated with drinking at least 2 glasses of water a day is:
- 70% of 50%(first group)
- 75% of 50%(second group)
Hence, applying the weighed percentage, the total percentage is:

0.725 = 72.5% of the team drinks at least 2 glasses of water a day.

Answer:

Step-by-step explanation:

(a) Rename h(x) as y

(b) Solve for x :

(d) Switch x and y

(e) Rename y as the inverse function

The graphs of inverse functions are reflections of each other across the line y = x.
In the diagram, the graph of h⁻¹(x) is the reflection of h(x) about the line y = x.
Answer:
a triangle always equals 180 degrees so
63+ 2x+8 + x+7 =180
solve for x
