Step-by-step explanation:
I DONT KNOW THE ANSWER ALL I KNOW IS TO USE BATMAN IF YOU KNOW WHAT THAT IS AND YEAH YOU WILL FIND THE ANSWER
We can do this in a few steps.
First: If it is 300 ounces per second then how many pounds per second?
1 ounce is 1/16 of a pound.
So we multiply 300 by 1/16.
300 x 1/16 = 300 ÷ 16 = 18.75
Now we know: 300 oz/sec equals 18.75 lbs/sec
But, we want to know how many lbs per minute (lbs/sec)
We need to calculate how many seconds are in a minute.
1 minute = 60 seconds.
We know how many lbs per second.
If we want to know how many lbs per minute, we multiply # of pounds per seconds by 60.
# pounds per second x 60 = # pounds per minute
# pounds per second: 18.75
18.75 x 60 = # lbs/min
18.75 x 60 = 1125
This means that 300 oz/sec => 1125 lbs/min
Comment: Wow, you have at least 390 math problems. That is insane! I've never had to do "the 390th math problem"!
Answer:
B
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here the vertex = (- 2, - 3 ) , then
y = a(x - (- 2))² - 3 , that is
y = a(x + 2)² - 3
To find a, substitute any point on the graph into the equation
Using the coordinates of the y- intercept (0, 5 )
5 = a(0 + 2)² - 3 ( add 3 to both sides )
8 = a(2)² = 4a ( divide both sides by 4 )
2 = a
y = 2(x + 2)² - 3 → B

For this case we have that by definition, the area of a rectangle is given by:
![A = a * b](https://tex.z-dn.net/?f=A%20%3D%20a%20%2A%20b)
Where:
a, b: They are the dimensions of the rectangle.
In the statement we are told that "The area is greater than 12 square inches", then:
![A> 12](https://tex.z-dn.net/?f=A%3E%2012)
Also we have:
![a = 2\\b = x](https://tex.z-dn.net/?f=a%20%3D%202%5C%5Cb%20%3D%20x)
Substituting we have:
![2x> 12](https://tex.z-dn.net/?f=2x%3E%2012)
Dividing between 2 on both sides:
![x> \frac {12} {2}\\x> 6](https://tex.z-dn.net/?f=x%3E%20%5Cfrac%20%7B12%7D%20%7B2%7D%5C%5Cx%3E%206)
Finally we have:
![x> 6](https://tex.z-dn.net/?f=x%3E%206)
