Loni needs between 3.5 and 7.2 volts of energy, not inclusive, to make an experiment work correctly. Write a compound inequality
1 answer:
Answer:
<em>The compound inequality that shows the voltage amount the necessary range is </em>
Step-by-step explanation:
Loni needs between 3.5 and 7.2 volts of energy, not inclusive, to make an experiment work correctly.
That means, <u>the voltage amount should be either greater than 3.5 volts or less than 7.2 volts</u>.
Suppose, the amount of voltage is volts to make the experiment work correctly.
Now, Voltage amount is greater than 3.5 volts means: or
and voltage amount is less than 7.2 volts means:
Thus, the compound inequality by combining the above two inequalities will be:

Answer:
The venue has to host 47 events throughout the year
Step-by-step explanation:
Profit:
Profit is revenue subtracted by costs.
Per event:
$100,000 revenue
$50,000 costs
$100,000 - $50,000 = $50,000 profit.
If the venue wants to make a total profit margin of $2,350,000, how many events does the venue have to host throughout the year?
1 event - $50,000 profit.
x events - $2,350,000 profit.
The venue has to host 47 events throughout the year
To solve this problem you must apply the proccedure shown below:
1. When you plot the given points, you obtain a trapezoid, therefore, you must apply the formula for calculate the area of a trapezoid, which is:
Where is the larger base,
is the smaller base and
is the height.
2. The dimensions are:
3. Substitute values:
The answer is:
