Answer: 60 trees
Explanation:
Even if there are trees planted per acre, the decrease of yield of each tree is significant enough to make it less worthwhile to have more trees than less.
In other words, when she plants 60 trees per acre, she gets 2700 bushels of fruit per acre, because 45 bushels per tree = 45 • 60 = 2700. If you plant another tree, you get the equation 41 • 61 = 2501 because there are 4 less bushels per tree. 2501 < 2700 so 60 per acre would maximize the harvest.
Answer: 0
Step-by-step explanation:
We can unsquare the squareroots:
x^2=36
Becomes
x=6 (because 6*6 is 36)
similarly,
y^2=81
Becomes:
y=9(because 9*9=81)
When you have a squareroot no matter if it’s negative or positive the result is a positive number.
Now we can solve and eliminate possible solutions.
For A) -9+(-6)=(-15)
For B) (-9)+6=(-3)
For D)(-6)+9=3
For E) 9+6=15
The only one that cannot be made is C)0
B) 12 miles and 12 gallons. The answer is B because gallons and miles are 2 completely different types of measurement. If you look at A, C, D, they all have the same measurements. I hope this helped!
Y=-5x-22
To be parallel to the other equation, the new equation needs to have the same slope, so the slope will be -5.
If you plot the point (-3,-7) and apply the slope, you will find that your new equation intersects the y-axis at (0,-22).
Hope this helps!
Answer:
Sx = 3 units
Step-by-step explanation:
use Pythagorean theorem:
a² + b² = c²
where a = h
b = 8/2 = 4
c = 5
plugin values into the formula:
h² + 4² = 5²
h² = 5² - 4²
x = √9
x = 3
