Answer:
3 times
Step-by-step explanation:
She has 1 1/2 hour to spend in the gym.
1 hr = 60 minute
1/2 of an hour
= 1/2 * 60
= 30 minutes.
In total, she spends 90 minutes in the gym.
If 1/3 of an hour is meant in running, it translates into;
1/3 * 60 = 20 minutes
If 1/6 of an hour is spent in weight-lifting, it translates into;
1/6 * 60 = 10 minutes
In total, she spends,
20 minutes + 10 minutes = 30 minutes for both activities.
To obtain the number of times she would perform both activities, we divide the total amount of time spent in the gym by the amount of time spent for both activities.
= 90 minutes/30 minutes
= 3 times for each cycle.
<u>Given:</u>
The given function is 
We need to determine the reflection of f(x) over the x - axis
<u>Reflection over x - axis:</u>
The translation rule to reflect over the x - axis is given by
Reflecting the function over the x - axis, we get;
Multiplying -1 to both sides of the equation, we have;
This can be written as
Hence, the reflection of the function over the x - axis is
Thus, Option A is the correct answer.

Answer: 15
Step-by-step explanation:
The difference between 36 and 19 means to subtract 19 from 36
36- 19 = 15
4 - (-7)
This will be the same as 4 - - 7
Which is 4 + 7
