<h3>
Answer: 2880 pounds per square foot</h3>
==========================================================
Explanation:
psi = pounds per square inch
1 foot = 12 inches
1 square foot = 144 square inches
I squared both sides to get the second equation. Think of a 12 by 12 square representing 12 inches along each side, so that leads to 12*12 = 144 square inches being the same as 1 square foot.
That last equation helps us convert from square inches to square feet like so:
Notice in the jump from the second step to the third step, we have the "square inches" unit cancel out when dividing. All that's left is "pounds" up top and "square foot" down below.
In short, we simply multiply by 144 to go from 20 to 2880.
<h2>Writing an linear equation from a given scenario</h2>
Answer:
Choice B
<h3>
Step-by-step explanation:</h3>
<em>Please refer to my answer from this question to know more about writing a </em><em>linear</em><em> </em><em>equation</em><em> from a given scenario: </em><em><u>brainly.com/question/24599307</u></em>
Scenario: A submarine dives 
feet per minute.
We let 
, be the position of the submarine from sea level as a function of 
, the time (in minutes) since the submarine dived.
The given scenario states that for every minute, the position of the submarine <u>decreases</u> (because the submarine is going in a downward direction) by feet. So 
can be defined as 
.
Now we can select two points for the graph. We can select points 
and 
.
Evaluation of function:
Our points are 
and 
Choice A doesn't touch our chosen points. In Choice C, it would be the case if the submarine is going in upward direct.
So the correct graph is Choice B.
Answer:
The larger number is 40, and the smaller one is 23.
Step-by-step explanation:
Let x be the larger number.
Let x - 17 be the smaller number.
x + (x - 17) = 63
2x - 17 = 63
2x = 80
x = 40
Hence, the smaller number is 40 - 17 = 23.
Hope this helped!
