Basically it's 2/3 for horses/acres so the answer would be 107.5 acres at least because 75/107.5 is 2/3.
Step-by-step explanation:
The first step in completing the square is to make the leading coefficient 1.
3 − 4x = 5x² − 14x
First, add 4x to both sides.
3 = 5x² − 10x
Divide both sides by 5.
3/5 = x² − 2x
The next step is to create the square. Take half of -2, square it, then add the result to both sides. (-2/2)² = 1.
3/5 + 1 = x² − 2x + 1
8/5 = x² − 2x + 1
Finally, factor the perfect square and solve for x.
8/5 = (x − 1)²
Take the square root of both sides.
±√(8/5) = x − 1
Add 1 to both sides.
x = 1 ± √(8/5)
Answer:
-6w + 11wy + 6 - 4y
Step-by-step explanation:
Step 1: Write out expression
-6w + 9wy + 6 + 2wy - 4y
Step 2: Combine like terms
-6w + 11wy + 6 - 4y
Use the rules of logarithm:
1. log(x)+log(y)=log(xy)
log(x)-log(y)=log(x/y)
2. k*log(x) = log(x^k)
log(x)/k = log(x^(1/k))
<span>log(2z)+2log(2x)+4log(9y)+12log(9x)−2log(2y)
=</span>log(2z)+log(4x^2)+log(9^4y^4)+log(9^12x^12)−log(4y^2)
=log(2z)+log(4x^2)+log(6561y^4)+log(282429536481x^12)−log(4y^2)
=log(59296646043258912 * x^14 * y^6 * z)
The area and the amount of gravel are illustrations of proportions.
7 lb will cover an area of 1 square foot, while 315 lb will cover an area of 45 square feet.
The given parameters are:
The number of pound for an area of <em>1 square foot </em>is calculated as follows:
So, we have:
Cross multiply
Divide both sides by 36
The area to be covered with 315lb gravel is calculated as follows:
So, we have:
Cross multiply
Divide both sides by 252
Hence, 7 lb will cover an area of 1 square foot, while 315 lb will cover an area of 45 square feet.
