Hello!</h2>
The answer is: True.
<h2>Why?</h2>
A counterexample is a way that we can prove that something is not true about a mathematical equation or expression, it's also considered as an exception to a rule.
So:
Then, evaluating we have:
Hence, we can see that the equation is not fulfilled, so, 45° is a counterexample for 
and the answer is true.
Have a nice day!

Answer:6 dollars
Step-by-step explanation:5 +20% gives you 6 which would be the ending price
Yes they will have enough
The total cost of the items was $298.20
We find this by taking the cost of 1 thing like the curtains, then we see how many were brought, which was 3. So we do the cost which is $24.50 and multiply that by 3 to get $73.50. And we keep doing this with the other items and add them up.
Answer: Hi!
So first, I'm going to convert "350 below ground level" to -350, as this is what "below ground level" represents.
Now, we should find the total distance traveled. Take the absolute value of -350 (350) and add it to 10, the metres above ground level. This is 360.
We already know the rate of travel; 6m/min. All we have to do now is divide the total distance (360) by the rate of travel (6)!
360 ÷ 6 = 60
So, it took 60 minutes, or one hour, for the elevator to travel down the shaft!
Hope this helps!
