<em>How many 2' x 4' would be needed for Bottom Plates and Double Top Plates on a Building 25' x 50' ?
</em>
<em></em>
Answer:
12.5 plates
Step-by-step explanation:
Given
Building dimension:
![Length = 25ft](https://tex.z-dn.net/?f=Length%20%3D%2025ft)
![Width = 50ft](https://tex.z-dn.net/?f=Width%20%3D%2050ft)
Plates
![Length = 2ft](https://tex.z-dn.net/?f=Length%20%3D%202ft)
![Width= 4ft](https://tex.z-dn.net/?f=Width%3D%204ft)
To do this, we have to divide the dimension of the building by the dimension of the plates
So, we have:
![n = \frac{Length\ of\ Building}{Length\ of\ Plates}](https://tex.z-dn.net/?f=n%20%3D%20%5Cfrac%7BLength%5C%20of%5C%20Building%7D%7BLength%5C%20of%5C%20Plates%7D)
and
![n = \frac{Width\ of\ Building}{Width\ of\ Plates}](https://tex.z-dn.net/?f=n%20%3D%20%5Cfrac%7BWidth%5C%20of%5C%20Building%7D%7BWidth%5C%20of%5C%20Plates%7D)
For the length, we have:
![n = \frac{25}{2}](https://tex.z-dn.net/?f=n%20%3D%20%5Cfrac%7B25%7D%7B2%7D)
![n = 12.5](https://tex.z-dn.net/?f=n%20%3D%2012.5)
For the width, we have:
![n = \frac{50}{4}](https://tex.z-dn.net/?f=n%20%3D%20%5Cfrac%7B50%7D%7B4%7D)
![n = 12.5](https://tex.z-dn.net/?f=n%20%3D%2012.5)
So, 12.5 of the plates are needed
What # are you talking about
Johnny ate 8 pies in 5 minutes
He must have ate 1 pie in (5/8) minutes
(5/8) minutes = 5/8 * 60 = 75/2 = 37.5 seconds
On each pie he spent 37.5 seconds.
Let's take these one at a time.
A
The A choice is that the y intercept of g(x) < y intercept of f(x). Remember, a y intercept occurs when x = 0
g(x) = 2 * sqrt(x) - 8
g(0) = 2*0 - 8
g(0) = - 8
=======
f(x) = - 4 when x = 0 (you just read it.) - 4 is greater than -8. That's a true statement. Think money. Would you rather be 4 dollars in debt or 8 dollars in debt?
A: True <<<<<< answer for A.
B
y intercept occurs when x = 0 The values of f(x) and g(x) have been found in part A.
Are they equal?
The y intercept of g(x) = g(0) = 2*sqrt(0) - 8 = - 8
The y intercept of f(x) = f(x) = - 4 when x = 0
Conclusion
They are not equal and B is not the answer.
C
The x intercept occurs when y = 0
g(x) = 0
0 = 2*sqrt(x) - 8
8 = 2*sqrt(x)
4 = sqrt(x)
x = 16
======
When f(x) = 0, x = 16.
Conclusion
The x intercepts are both 16. This statement is true.
C: True <<<<<< answer.
D
If the condition is anything but equal, the statement is false. g(x) is not greater then f(x).
D <<<<<< False.
