Using the exponential function, it is found that the oxygen level at 10 miles is of 59.87 ppm.
<h3>What is the exponential function for the oxygen levels?</h3>
The oxygen levels in ppm for an altitude of x miles at the Mount Everest is given by the following exponential function:
In this problem, the altitude is of x = 10 miles, hence the oxygen level in ppm is of:

425 / 2500 = 0.17 = 17%
so 17% of 2500 is 425
Value of x is 1/5
Step-by-step explanation:
- Step 1: Given equation is 4 = √6x + 15 - x. Square both sides of the equation.
⇒ 16 = 6x + 15 - x
⇒ 16 = 5x + 15
⇒ 1 = 5x
∴ x = 1/5
36 erasers shared in the ratio 6 is 6 (36/6)
So the is 6 in 1 ratio.
6 x the ratio 2 is 12
So there are 12 pencils
Answer:
23 children and 9 adults
p <= 70/9
Step-by-step explanation:
Let x = # of adults and y = # of children. The number of children is 5 more than twice the number of adults, so x = 2y + 5. The total cost of entrance is $6525, so 225x + 150y = 6525.
x = 2y + 5
225x + 150y = 6525
x - 2y = 5
225x + 150y = 6525
75x - 150y = 375
225x + 150y = 6525
300x = 6900
x = 23
x = 2y + 5
23 = 2y + 5
18 = 2y
y = 9
225p + 3750 <= 5500
225p <= 1750
p <= 70/9
