Answer:
15/32
10/9 = 1 1/9
26/15 = 1 11/15
Step-by-step explanation:
3/8 / 4/5 = 3/8 * 5/4 = 15/32
8/9 / 4/5 = 8/9 * 5/4 = 40/36 = 10/9 = 1 1/9
2 3/5 / 1 1/2 = 13/5 / 3/2 = 13/5 * 2/3 = 26/15 = 1 11/15
Slimplify 2-2/3 to 4/3
1/2*2-6*4/3
slimplify 1/2*2 to 1
1-6*4/3
slimplify 6*4/3 to 24/3
1-24/3
slimplify 24/3 to 8
1-8

Answer: 
Step-by-step explanation:
By definition scientific notation has the following form:

Where a is a number between 1 and 10 but not including 10, and the exponent b is an integer.
The decimal point must be after the first digit.
Therefore, keeping the information above on mind, you can write the number as following:

9514 1404 393
Answer:
13064 feet
Step-by-step explanation:
We can rewrite the formula so that x is in feet. Equating the new formula to 8.743 PSI, we have ...
8.743 = 14.7e^(-0.21x/5280)
Dividing by 14.7 and taking natural logs, we have ...
ln(8.743/14.7) = -0.21x/5280
Multiplying by the inverse of the coefficient of x gives ...
x = 5280·ln(8.743/14.7)/-0.21 ≈ 13064.0806
The peak of the mountain is about 13,064 feet high.
