hello :)
so the intial temperature was:
-10
and if it dropped 24 then this is the equation you want to solve
-10-24
so the new temperature would be
-34 degrees
hope this helped!
Step-by-step explanation:
Get the square root of 316 which is 17.8
To get surface area you do cross section area x6
17.8×17.8×6=1896
To get volume you do length ×height ×width
17.8×17.8×17.8=5639.752cm³ or 5640cm³ if rounded off
Here are two ways to solve
Method 1: Elimination
x+y = 3k ... start with the first equation
4x+4y = 12k ... multiply every term by 4
4x-6k = 2y ... move onto the second equation
4x-2y = 6k ... subtract 2y from both sides and add 6k to both sides
The system of equations turns into
4x+4y = 12k
4x-2y = 6k
which, when subtracted, leads to 0x+6y = 6k so y = k when you divide both sides by 6
Use y = k to find x
x+y = 3k
x+k = 3k
x = 2k
The answer is 2k
=========================================================================================
Method 2: Substitution
x+y = 3k ... start with the first equation
y = -x+3k ... isolate y; subtract x from both sides
4x-6k = 2y ... move onto the second equation
4x-6k = 2(-x+3k) ... plug in y = -x+3k; solve for x
4x-6k = -2x+6k
4x+2x = 6k+6k
6x = 12k
x = 12k/6
x = 2k
=========================================================================================
Whichever method you use, the answer is x = 2k
You use the formula:
<span>A = angles/360*pi*r^2
</span>A = 32/360pi*8.5^2 = 0.279* 72.25= 20.15775 rounded to 20.2
I hope that this is the answer that you were looking for and it has helped you.
Answer:
Opposites are basically the negative and positive of a number. I cannot think of something for a real world situation though.
