The problem has to do with finding what percentage is one quantity over another.
We can solve as a rule of three, knowing that <span>$27,650 is the 100%
</span><span>$27,650 ----> 100%
1382.5 ------> x
x = (1382.5)(100)/</span><span>27650
x = 5
therefore, $</span>1382.5 is the 5% of $<span>27650</span>
Answer:
g = 9. I hope that I help my buddy out :)
Answer:
k = 13
Step-by-step explanation:
Matrix is;
A =
[2 -5 9]
[-1 3 -5]
[ 7 1 k ]
Number of unknowns is less than the rank of 2. Thus, the determinant has to be zero for us to find k.
Thus, we have;
2((3 × k) - (-5 × 1)) -(-5)((-1 × k) - (-5 × 7)) + 9((-1 × 1) - (7 × 3)) = 0
Simplifying further gives;
2(3k +5) + 5(-k + 35) + 9(-22) = 0
6k + 10 - 5k + 175 - 198 = 0
k - 198 + 185 = 0
k - 13 = 0
k = 13
Sin(x) = opposite over hypotenuse
Cos(x) = adjacent over hypotenuse
Tan(x) = opposite over adjacent
Everything revolves around a right triangle.
From the given equation, "<span>sine of x equals square root of 2 over 2"
Opposite = square root of 2
Hypotenuse = 2
Adjacent = ?
Using the Pythagorean Equation: H^2 = O^2 + A^2
2^2 = (square root of 2)^2 + A^2
A^2 = 4 - 2
A = square root of 2
Cos(x) = square root of 2 over 2
Tan(x) = square root of 2 over square root of 2 = 1</span>
