Answer:
He should buy 189.47 feets.
Step-by-step explanation:
Since there's a hypotenuse this triangle is rectangular and since it's an isosceles triangle we know that both cathetus are equal. We were given the area of this triangle, wich is 4500 square feet, the equation to compute this area is A = b*h/2, since the cathetus are equal b = h and we can solve for either of this variables. So we have:
A = b*b/2
4500 = b*b/2
b*b= 9000
b = sqrt(9000) = 94.87 feet
Since the hypotenuse of this triangle already has a fence we only need to buy the fencing for the cathetus, wich should be two times b, since there are two cathetus. So the amount of fence is 2*b = 2*94.87 = 189.74 feets.

i dont know
Step-by-step explanation:
Short Answer P(6/5,y) = P(1.2,y)
RemarkThis problem is solved by a formula known as the section formula. If you want to divide a line into any ratio other than 1:1, this formula will do it for you.
GivensLine segment with endpoints (-4,-8) and (9,3)
y2 = 3
y1 = -8
x2 = 9
x1 = - 4
m=2
n = 3
Desired ratio
m = 3
n = 2
m:n = 3:2
FormulaP(x,y) =
Sub and SolveP(x,y) =

P(x,y) =

P(x,y)
conclusionThe point you want is
P(6/5,-18/5) If you measure the length with a ruler, you should see that the ratio the line is cut into is 2 : 3
Note: This question all depends on where you start from and what you call (x1,y1) and (x2,y2). Be prepared to argue the point if this answer is incorrect. Point C on my graph is the answer.
7 * 1 3/4
7 * 1 = 7
7 * 3/4 = 21 / 4 = 5.25
7 + 5.25 = 12.25
