Answer:
1/2 (150 -2x)
Step-by-step explanation:
You know queen parallela has 150 meters to build her pen. That means that the perimeter of the pen must be 150 (meters), therefore if x is the width and L is the lenght, we have
2*x + 2*L = 150
We want the value of L in terms of x, so we will send 2*x to the other side of the equation and we have
2*L = 150 - 2*x
Therefore
L = (150-2*x)*1/2
The correct answer is 1/2 (150 -2x)
I hope this helped you!
140 is a composite number. Factor pairs: 140 = 1 x 140, 2 x 70, 4 x 35, 5 x 28, 7 x 20, 10 x 14. Factors of 140: 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140. Prime factorization: 140 = 2 x 2 x 5 x 7, which can also be written 140 = 2² x 5 x 7
The easiest way is to plug x=-4, y=-1 in the equation to see which one works.
8(-4)-9(-1)=-23
B is correct.
Answer:
$224
Step-by-step explanation:
You purchased the stock at $12.77 per share, so the total amount you purchase for is:
400 shares * $12.77 = $5108
You spent $5108 on the stock shares.
You sold the stock at $13.33 per share, so the total amount you sold for is
400 shares * $13.33 = $5332
You got $5332 by selling the stock shares.
Profit = $5332 - $5108 = $224
Answer:
represent the random sample selected
represent the number of pots that were bare ground (no vegetation
And replacing we got:
So then the sample proportion of bare ground spots is 0.792 for this sample
Step-by-step explanation:
We have the following info given from the problem:
represent the random sample selected
represent the number of pots that were bare ground (no vegetation)
And for this case if we want to find the sample proportion of bare ground spots we can use this formula:
And replacing we got:
So then the sample proportion of bare ground spots is 0.792 for this sample
