Irina-Kira [14]

Answer:

73 feet.

Step-by-step explanation:

Given:

A rope from the top of a pole is anchored to the ground which is 55 ft away from the base of the pole.

The pole is 48 ft tall.

Question asked:

What is the length of the rope?

Solution:

Here we found that a right angle triangle is formed in which base and height is given as shown in the figure, we have to find the longest side of the triangle,

Base = 55 feet

Height = 48 feet

Length of the rope = ?

By Pythagoras theorem:

Square of longest side = Square of base + Square of height

$(Longest\ side)^{2} =$ $55^{2} +48^{2}$

$(Longest\ side)^{2} =$ $3025+2304$

$(Longest\ side)^{2} =$ $5329$

Taking root both side

$\sqrt[2]{(Longest\ side)^{2} } =\sqrt[2]{5329}$

$Longest\ side =$ $73$

Thus, length of the rope is 73 feet.

Darina [25.2K]

Manuel bought pounds of apples and eat 3/4 of 1 pound
That is 0.75 pounds
Thus 9-0.75=8.25 pounds of apples left with him.
It is given that the cost of 25 pounds of Apple is dollar.
Let the cost of 1 pound of Apple be x.

8.25 multiply X=15

8.25x. 10
————. = ——
8.25. 8.25

X=10
——
8.25

X=1.818181

X=2

Then the cost of Apple is above two dollars per pound
