Answer:
y=640-3x
Step-by-step explanation:
The total amount of ounces in the bucket is 640, and it decreases by 3 each minute. For example, if you plug in 3 for x into that equation (which would represent 3 minutes), you would lose 9 ounces of water, which makes sense in the terms of the equation.
Yes there is actually a formula for this. This is an arithmetic progression with a common difference of 1.
The sum of terms can be solved by using the formula
S = (n/2) * (a1 + an)
where S is the sum of the terms
n is the number of terms
a1 is the first term
an is the last term
we can calculate the number of terms, n by using the formula
an = a1 + (n-1)*d
d is the common difference equal to 1
therefore n = 51
substituting to the first equation
S = 2805
Answer:
Step-by-step explanation:
What you wrote below the top line and the bottom line are not the same thing.
I think you really want the second line, but one can't be sure.
(1*2 + 5)/2 div (9/8)
7/2 // 9/8
7/2 * 8*9
7*8/18 = 56/18 = 28/9
If you really do want the top line (the latex) it is different.
1 2/5 div (8/9) Is there such a thing as tfrac? I didn't know this but there is.
(1*5 + 2)5 // (8/9)
7/5 // 8/9 Invert the bottom fraction and multiply
7/5 * 9 / 8
63 / 40
1 23/40
Answer:
Step-by-step explanation:
<u>Step 1</u>:-
Given problem is [(x + 1)(x - 1)]^2
by using formula in side square bracket is
![[x^{2} -1]^{2}](https://tex.z-dn.net/?f=%5Bx%5E%7B2%7D%20-1%5D%5E%7B2%7D)
<u>Step 2</u>:- again we will use formula
^{2} = (x^{2}) ^{2} -2 x^{2} (1)+1^{2}](https://tex.z-dn.net/?f=%5Btex%5D%28x%5E2-1%29%5E%7B2%7D%20%3D%20%28x%5E%7B2%7D%29%20%5E%7B2%7D%20-2%20x%5E%7B2%7D%20%20%281%29%2B1%5E%7B2%7D)
