Jaime had ten posters, but only five could fit on his closet door. how many
1 answer:
There are 30240 different ways can he arrange the five posters out of the ten on his closet door
<h3>How to determine the number of arrangements?</h3>The given parameters are:
- Total, n = 10
- Posters to arrange, r = 5
The number of ways is calculated as:
Ways =
This gives
Ways =
Apply the permutation formula
Ways = 30240
Hence, there are 30240 different ways can he arrange the five posters out of the ten on his closet door

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
