Answer:
Length of the longer piece be 105 ft .
Step-by-step explanation:
As given
Mauro has 140 ft of rope.
He will cut it into two pieces so that the length of the longer piece is 3 times the length of the shorter piece.
Let us assume that the length of the shorter piece be x.
Length of the Longer piece = 3x
Than the equation become
3x + x = 140
4x = 140
x = 35 ft
Length of the longer piece = 3 × 35
= 105 ft
Therefore the length of the longer piece be 105 ft .

Answer:
The distance between the base of the tree and the flower is 9m
Step-by-step explanation:
Here, we have to paint a picture.
The flower is on the ground, the height of the tree is 12m.
The distance from the nest to the flower on the floor is 15m
Indisputably, what we have is a right angled triangle, with the height being 12m, the length of the hypotenuse being 15 and we are asked to calculate the adjacent which represents the distance from the base of the tree to the flower
To get this distance, we simply apply the Pythagoras’ theorem which states that the square of the hypotenuse(longest side of the triangle) is equal to the sum of the squares of the other two sides.
Thus mathematically, we know that our hypotenuse is 15m and the height is 12m
The length we are to calculate is the adjacent and it is equal to;
15^2 - 12^2
= 225 - 144
= 81
The length is thus
√(81) = 9m
