Esitmate:
9 /3 = 3
and
8-4 = 4
so it would be 3x10^4
answer is C
Here are the answers to the questions above:
1. Based on the list of fees above, the one that does not contribute to the <span>initial cost of leasing a car is the FINAL PAYMENT. Answer would be option B.
2. In leasing a car, the amount that does not affect the total cost is the PRINCIPAL CHARGE, and the answer for this is option A.
Hope this helps.</span>
Answer:
Firstly need to understand the questions.
If 15 men working 10 days, They earn 500.
If 12 men working 14 days, how much they will earn?
Step-by-step explanation:
560
Solution:
15 men working for 10 days =500
1 man working for 1 day = 500/(10*15) =10/3
Now 12 men working for 14 days = 12*14*10/3 =560.
I am pretty sure that answer is right.
Thank you :)

a. The equation that describes the forces which act in the x-direction:
<span> Fx = 200 * cos 30 </span>
<span>
b. The equation which describes the forces which act in the y-direction: </span>
<span> Fy = 200 * sin 30 </span>
<span>c. The x and y components of the force of tension: </span>
<span> Tx = Fx = 200 * cos 30 </span>
<span> Ty = Fy = 200 * sin 30 </span>
d.<span>Since desk does not budge, </span><span>frictional force = Fx
= 200 * cos 30 </span>
<span> Normal force </span><span>= 50 * g - Fy
= 50 g - 200 * sin 30

6)<span> Let F_net = 0</span>
a. The equation that describes the forces which act in the x-direction:
(200N)cos(30) - F_s = 0
b. The equation that describes the forces which act in the y-direction:
F_N - (200N)sin(30) - mg = 0
c. The values of friction and normal forces will be:
Friction force= (200N)cos(30),
The Normal force is not 490N in either case...
Case 1 (pulling up)
F_N = mg - (200N)sin(30) = 50g - 100N = 390N
Case 2 (pushing down)
F_N = mg + (200N)sin(30) = 50g + 100N = 590N
ANSWER: ∠T = 32.4°
Remember the formula for the basic trig functions: SOH CAH TOA
Since you want to find cosine for <T, you need the adjacent side length as well as the hypotenuse's length which can be found using the Pythagoras's Theorem 
with <em>a </em> and <em>b</em> being the side lengths and <em>c</em> being the hypotenuse.
Using the theorem, we get c=37
Now use the cosine formula to get <T = 12/37 to get the final answer.
