Answer: 362,880
Step-by-step explanation: At first glance of the question, it doesn't seem that the order matters, which would make it a question of how many combinations there are. The simple way to look at it is that there are 9 trees and he's planting 8, leaving out 1. Since there are 9 possible trees to leave out, there are 9 possible combinations of which 8 trees to plant.
The formula would be 9!/([9-8]!*8!) = 9
If the question is indeed asking for permutations (order matters), since you are choosing 8 out of 9 the formula would be 9!/(9-8)! = 9!/1! = 9! = 362,880
Answer:
17》6
18》12
19》8
20》3
21》2
the bar with age 18 this is because as you minus from both sides the middle number will be in age 18
Im pretty positive that it is 93/44

The question in English is
A tank is filled with water daily to give water to the animals on a farm. As required, 3/8 of the water was taken from the tank to give to the horses and 1/3 of what was left in the tank was given to the pigs. The remainder of the tank was distributed in two equal amounts to give water to the birds and pets. What is the fraction of the water that pets receive to drink?
1) 3/8 of the water was taken from the tank to give to the horses
At this point in the tank there are 1-3/8=5/8 of the water of the tank
2) 1/3 of what was left in the tank was given to the pigs
At this point in the tank there are
(1-1/3)*5/8
(2/3)(5/8)=10/24 of the water of the tank
3) The remainder of the tank was distributed in two equal amounts to give water to the birds and pets
The remainder is equal to 10/24
divided by 2
(10/24)/2=10/48
4) The fraction of the water that pets receive to drink is 10/48
simplify
10/48=5/24
Answer:
Step-by-step explanation:
1) Angle 1 and angle 2 are complementary angles. If angle 1 measures (3x + 2), what is the measure of angle 2? 3x+2 + y = 90
2) Angle A and angle b are supplementary angles. Angle A measures (2m – 10) degrees and angle b measures (m + 25) degrees. Find the measure of angle A and angle b.
3) Three angles are supplementary angles. If one angle measures 25 degrees, the second angle measures m + 15. The third angle measures 2m degrees. What is the value of m?
