Total number of marbles = 88
Number of red marbles = 25% x 88 = 0.25 x 88 = 22
Answer: There are 22 red marbles in the tin.
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:

Answer:
x = 30
y = 14
Step-by-step explanation:
If the linear pairs are equal, then we can conclude that the angle on each of the sides is 90
Thus 3x = 90
and x = 90/3 = 30
Also;
9y - 36 = 90
9y = 90 + 36
9y = 126
y = 126/9
y = 14
For every 3 seconds, the scuba diver dives 0.5 feet
after 15 seconds = your answer
3 x 5 = 15
0.5 x 5 = your answer
your answer = 2.5
2.5 is your answer

We have an equation: ?/12= 1/4
Cross multiply:
4*?= 1*12
⇒ ?= 1*12/4= 3
