Answer:
y = -6
Step-by-step explanation:
6 + 6y = -30
6y = -30 - 6
6y = -36
y = -6
The volume of the marbles is 26-20.9 = 5.1 l and there ar e85 marbles
5.1/85 = .06 l/marble
then 200 marbles would requrie .06 l/marble x 200 marbles = 12 liters
so he would only need 26-12= 14 liters of water to fill the tank !
Using the slope concept, it is found that the change in elevation was of -699 feet.
<h3>What is a slope?</h3>
The slope is given by the <u>vertical change divided by the horizontal change</u>, and it's also the tangent of the angle of depression.
In this problem, we have that:
- The vertical change is of h.
- The horizontal change is of 10,000 feet.
Hence:
tan(-4º) = h/10000
h = 10000 x tan(-4º)
h = -699.

<span>Test if 8 is divisible by all possible numbers. Start by testing the smallest number possible (1) and making your way up to the largest number possible (7).
8/1= 8
8/2=4
8/3= not a whole number
8/4 = 2
8/5 = not a whole number
8/6 = not a whole number
8/7 = not a whole number
note we did not try 8/8 because that would not be considered "taking apart".
After sorting out our test answers we can conclude that you can take 8 apart in three ways. In 8 groups of 1, in 2 groups of 4, and in 4 groups of 2. You can show this in pictures by illustrating these groups. See Below
