Given:
The selling price of a ratio set = 72.00
Profit percent = 8%
To find:
The cost price for the radio set.
Solution:
Let x be the cost price for the radio set.
Radio set is sold at 8% profit.
![\text{Selling price}=x+\dfrac{8}{100}x](https://tex.z-dn.net/?f=%5Ctext%7BSelling%20price%7D%3Dx%2B%5Cdfrac%7B8%7D%7B100%7Dx)
![\text{Selling price}=x+0.08x](https://tex.z-dn.net/?f=%5Ctext%7BSelling%20price%7D%3Dx%2B0.08x)
![\text{Selling price}=1.08x](https://tex.z-dn.net/?f=%5Ctext%7BSelling%20price%7D%3D1.08x)
The selling price of a ratio set is 72.00.
![72=1.08x](https://tex.z-dn.net/?f=72%3D1.08x)
![\dfrac{72}{1.08}=x](https://tex.z-dn.net/?f=%5Cdfrac%7B72%7D%7B1.08%7D%3Dx)
![x=66.666...](https://tex.z-dn.net/?f=x%3D66.666...)
![x\approx 67](https://tex.z-dn.net/?f=x%5Capprox%2067)
Therefore, the cost price for the radio set is 67.
Answer:
Step-by-step explanation:
This is one minus the probability that all the girls audition for different roles. The total number of ways of assigning roles to the girls is 12^7, because to each of the 7 girls, you have a choice of 12 roles.
Then if each girl is to receive a different role, then there are 12!/5! possibilities for that. If you start assigning roles to the girls, then for the first girl, there are 12 choices, but for the next you have to choose one of the 11 different ones, so 11 for the next, and then one of the 10 remaining for the next etc. etc., and this is 12*11*10*...*6 = 12!/(12-7)! =12!/5!
The probability that a random assignment of one of the 12^7 roles would happen to be one of the 12!/5! roles where each girl has a different role, is
(12!/5!)/12^7 = 12!/(12^7 5!)
Then the probability that two or more girls addition for the same part is the probability that not all the girls are assigned different roles, this is thus:
1 - 12!/(12^7 5!)
Step-by-step explanation:
Actual graph for this problem is attached below
m∠TUV = 167°
m∠TUL = (x + 11)°
m∠LUV = (11x)°
m∠TUV=
m∠TUL+
m∠LUV
now plug in the angles for each
m∠TUV=
m∠TUL+
m∠LUV
![167= x+11 +11x](https://tex.z-dn.net/?f=167%3D%20x%2B11%20%2B11x)
solve the equation for x
![167= x+11 +11x\\167=11 +12x](https://tex.z-dn.net/?f=167%3D%20x%2B11%20%2B11x%5C%5C167%3D11%20%2B12x)
Subtract 11 from both sides
![156=12x](https://tex.z-dn.net/?f=156%3D12x)
divide both sides by 12
x=13
m∠TUL = (x + 11)°
m∠TUL = (13+ 11)°
= (24)°
answer:
24°
