Answer:
The first buy
Step-by-step explanation:
Answer: 1,6 2,2 5,0 These are the correct answers.
Step-by-step explanation:
He sold his entire stock for $10000.
Let the number of shirts be x.
Let the number of ties be y.
The shirt is at 3 for $100. Therefore, a shirt would cost $(100/3)
The tie cost $20 each.
Therefore, Multiplying by the number of shirts and ties:
100x / 3 + 20y = 10000 .............(i).
If he had sold half the shirts and two-thirds the ties, the equation becomes:
100/3 * (x/2) + 20 * (2y / 3) = 6000
50x / 3 + 40y / 3 = 6000 ..............(ii)
Multiply equation (ii) by 2.
2*(50x / 3 + 40y / 3 ) = 2* 6000
100x / 3 + 80y / 3 = 12000 .........(iii).
Equation (i) Minus (iii) . Inorder to eliminate x.
100x / 3 - 100x / 3 + 20y - 80y / 3 = 10000 - 12000
-20y / 3 = - 2000.
y = 3 * 2000 / 20
y = 300.
Substituting into equation (i).
100x / 3 + 20y = 10000
100x / 3 + 20*300 = 10000
100x / 3 + 6000 = 10000
100x / 3 = 10000 - 6000
100x / 3 = 4000
x = 4000 * 3 / 100
x = 120.
So he actually sold 120 shirts and 300 ties. Cheers.
Answer:
The distance of needle cover as it rotate is 0.700688 cm
Step-by-step explanation:
Given as :
The length of the needle = r = 24 cm
The needle is rotated at angle = Ф = 96°
The distance of needle cover as it rotate = length of arc made = l cm
The radius of arc = length of needle = r cm
<u>Now, According to question</u>
The distance of needle cover as it rotate = 
where , π = 3.14
Or, l = 
Or, I = 
Or, l = 75.36 × 0.533°
∵ 180° = 3.14 radian
So, 0.533° = 0.0092978
So, l = 75.36 × 0.0092978
∴ l = 0.700688 cm
So,The distance of needle cover as it rotate = l = 0.700688 cm
Hence, The distance of needle cover as it rotate is 0.700688 cm Answer
I think all of them are possible if there is no type of triangle needed
