Think of the 13-ft length of the ladder as the hypotenuse of a right triangle. Represent the horiz. distance from foot of ladder to base of tree by x, or 5 ft.
Represent the vert. dist. from base of tree to top of ladder by y, which is unknown.
Then (13 ft)^2 = (5 ft)^2 + y^2, or
169 ft^2 = 25 ft^2 + y^2. This simplifies to y^2 = 144. Thus y = + 12 feeet.
Note: Please pay attention to your spelling: "lader i up agenst a tree" should be "the top of a 13-ft ladder is placed against a tree."
Assuming the garden is a rectangle, the area is equal to length times width.
So 20x = 760.
Divide both sides by 20.
x = 760/20 = 38 ft
Cost of the 3 shirts before tax = 2*49.96 + 1/2 * 49.96
= $124.90
After adding 7.1% tax total cost = 124.90 * 1.071 = $133.77
So the cost od each shirt = 133.77 / 3 = $44.59 (answer)
3,345 divided by 18 is 185.8333....The three goes on forever.
Steps:
Does 18 go into 3? No
Does 18 go into 33? Yes
How many times? 1
33-18= 15, and then you would bring down and keep doing what I did. Hope this helped!
2x^2 + 25x + 50 not sure about the steps
