Answer:
59 feet per second
Step-by-step explanation:
- (40m)(5280ft)=211,200 ft/hr

- 58.7 ft/s
You haven't provided any value, but I can tell you the solution set for the inequality.
First of all, expand both sides:
![-3x+12 > 6x-6](https://tex.z-dn.net/?f=%20-3x%2B12%20%3E%206x-6%20)
Add 3x to both sides:
![12 > 9x-6](https://tex.z-dn.net/?f=%2012%20%3E%209x-6%20)
Add 6 to both sides:
![18 > 9x](https://tex.z-dn.net/?f=%2018%20%3E%209x%20)
Which is of course equivalent to
![9x < 18](https://tex.z-dn.net/?f=%209x%20%3C%2018%20)
Divide both sides by 9
![x < 2](https://tex.z-dn.net/?f=%20x%20%3C%202%20)
So, every number smaller than 2 is part of the solution of this inequality.
Let us take the case of first type of tea
Cost of 10 kg of tea one = $20
Then
Cost of 1 kg of tea one = (20/10) dollars
= 2 dollars
Now let us take the case of the second kind of tea
Cost of 10 kg of tea = $23
Then
Cost of 1 kg of tea = (23/10) dollars
= 2.3 dollars
So
The mixture of 1 kg of tea one
and 1 kg of second type of tea will cost = (2.0 + 2.3) dollars
= 4.3 dollars
Then the cost of 2kg mixture of tea costs = 4.3 dollars
So
The cost of 10 kg mixture will cost = (4.3/2) * 10 dollars
= 4.3 * 5 dollars
= 21.5 dollars
Then
The amount of profit made by selling 10 kg tea at $38 = (38 - 21.5) dollars
= 16.5 dollars
So
Percentage of profit made = (16.5/21.5) * 100
= 1650/21.5
= 76.74 percent
So the percentage of profit made is 76.74%.
