Answer:
Step-by-step explanation:
Tan(a/2) = sin a / (1 + cos a)
tan(45/2) = sin(45) / (1 + cos(45)) = (1/√2) / (1 + 1/√2) = (1/√2) / (√2 + 1)/√2 = 1/(√2 + 1) = (√2 - 1)
Answer:
£12000
Step-by-step explanation:
Granddaughter -- 1/2 of x
Grandson -- 1/2(1/2 of x)
Brother -- 1/6 of x
Dogs' home -- £1000
Therefore,

x = 12000
Thenks and mark me brainliest :)
the answer is 1/8. Because you divide how many pieces there are by that same number.
Answer:
3 hours 40 minutes.
Step-by-step explanation:
We are told that we have 1320 garments and it takes an employee 20 seconds to tag a garment.
1 employee tags one garment in 20 seconds.
So garments tagged by 1 employees in 1 minute will be
garments.
2 employees will tag 3*2=6 garments in 1 minute.
To find the total time it will take two employees to tag all the garments we will divide total number of garments by 6.


Therefore, it will take 220 minutes or 3 hours and 40 minutes for 2 employees to tag 1320 garments.
