Answer:
5/6
Step-by-step explanation:
we add all the marbles together to get 6
then we seperate the marbles according to the question which would be yellow and red. that would make the probability of getting one of those to 5/6. Hope this helps :)
<em>It will take 6 minutes to drain the pool.</em>
<h2>
Explanation:</h2>
As the problem states the height of the water in an above ground pool is 3ft. In other word:
- 3 ft is our starting point.
The pool needs to be drained at a Rate of Change of 1/2 inches per minutes. In other words:
- The rate of change is constant, so we'll have a line with slope -1/2.
Therefore, we can write an equation as:
To drain the pool implies that we don't have any water in the pool, in other words this is true if and only if:
So:
So, <em>it will take 6 minutes to drain the pool.</em>

Answer:
A
Step-by-step explanation:
Answer:
x-intercept is (40/7, 0) and y-intercept is (0, 5)
Step-by-step explanation:
x-intercept ==> y-coordinate is 0 ==> y=0
y-intercept ==> x-coordinate is 0 ==> x=0
because the function is 7x + 8y = 40
when y = 0 ==> 7x = 40 ==> x = 40/7
so the x-intercept is (40/7, 0)
when x = 0 ==> 8y = 40 ==> y = 5
so the y-intercept is (0,5)
A.) Here, w = 550kg/m^3.
Therefore, S = (0.032(550) - 2.5)/10000 = 0.00151
After drying, the beam will be (1 - 0.00151) x 12.027 = 12.009
b.) 0.0012 = (0.032w - 2.5)/10000
0.032w - 2.5 = 12
0.032w = 12 + 2.5 = 14.5
w = 14.5/0.032 = 453 kg/m^3
Therefore, the required water content is 453 kg/m^3
