Answer:
The value of pressure at an altitude of 10000 ft = 10 
Step-by-step explanation:
Given data
Atmospheric pressure 
= 14.7
Pressure at 4000 ft = 12.6
If temperature is constant then the atmospheric pressure is varies with the altitude according to law
P (h) = 
------ (1)
where k= constant & h = height
12.6 = 14.7 
0.857 =
㏑ 0.857 = - 4000 k
-0.154 = - 4000 k
k = 3.85 × 
Thus the atmospheric pressure at an altitude of 10,000 ft is
14.7 × ----- (2)
Product of k & h is
k h = 3.85 × × 10000
k h = 0.385
Put his value of k h = 0.385 in equation (2) we get
14.7 × 
10
This is the value of pressure at an altitude of 10000 ft.

Solution and Answer:
15/17 ≈ 0.88
15/17 cannot be simplified because 17 is a prime number and both numbers don't have common prime factors.

Hope This Helped! Good Luck!
Answer:
1/45
Step-by-step explanation:
There are 10 marbles
P ( yellow) = yellow marbles / total = 2/10 = 1/5
We do not replace the marble
There are 9 marbles, 1 of which is yellow
P ( yellow) = yellow marbles / total = 1/9
P ( yellow, no replacement, yellow) = 1/5 * 1/9 = 1/45
$32.50 would be your answer for all of those :) good luck :)
