Rectangle and a triangular prism
Solving for Rectangle...
Volume = Length · Width · Height
Volume = 30 · 13 · 13
Volume = 5070 in
Solving for Triangular Prism
Volume = Length · Width · Height / 2
Volume = 30 · 9 · 13 / 2
Volume = 3510/2
Volume = 1755 in
Finally, add the volumes!
5070 + 1755 = 6825 in

Answer: 0.44mm
Step-by-step explanation:
In this problem we are asked for the height of a single playing chip. We know the volume of a cylinder is 25120 mm^3.
V=πr²h
25120=πr²h
The problem also gives the diameter of the case: 40mm.
To find radius, you divide the diameter in half.
d=2r
40=2r
r=20
With the radius, we can add that to the volume equation.
25120=(20)^2h
25120=400πh
All we have left is to find the height.
h=25120/(400π)
h≈20mm
Now that we know the height, we can find the height of a single chip. The problem states about 50 chips can fit in a case. To find the height of a single chip, you would divide 20 by 50.
20mm/50 chips=0.4mm/chip.

Final answer:
The pattern in this sequence is subtracting 3 each time. The next three terms in the sequence are -7, -10, and -13, making the correct answer option a.
Explanation:
The pattern in this sequence is decreasing by 3 each time. To find the next number in the sequence, we subtract 3 from the last number. So, for this numerical sequence: 5, 2, -1, -4, the next three terms would be -7, -10, and -13. Therefore, the correct answer is option a which states: Subtract 3; -7, -10, -13.
Let's explain this in steps:
- We begin with 5.
- Subtract 3 from 5, we get 2.
- Subtract 3 from 2, we get -1.
- Subtract 3 from -1, we get -4.
- Continuing this pattern, subtract 3 from -4, we get -7 (first next term).
- Subtract 3 from -7, we get -10 (second next term).
- Subtract 3 from -10, we get -13 (third next term).

We multiply both sides of the equation by 3x:
We multiply both sides of the equation by 2:
From here, we clear the value of x:
Answer:
You can not divide by zero, but you can rewrite the expression to clear x.
The value of x is given by:
Taking the LCM on the left side
(9 + x)/(3x) = (5/6)
54 + 6x = 15x
From this step, it is visible that x is no longer in th denominator and even if it is 0, the equation is solvable.
9x = 54
x = 6
