. If its diameter measures 30 units, find its height.
The height of the right cone given its volume and its diameter is 47 units.
What is the height?A cone is a three-dimensional object that has a circular base and a vertex.
Height of the cone = Volume of a cone ÷ 1/3(πr²)
Where:
π = 22/7r = radius = diameter / 2 = 30 / 2 = 15 unitsh = height3525π÷ (1/3 x π x 15²) = 47 units

Select ALL the sets that are the three side lengths of right triangles.
Answer:
c and d, b
Step-by-step explanation:
a - 49+64 = 113 so not a rt triangle
b - 16+100 = 116 again not rt triangle but 84+16 = 100 which is a rt triangle
c - 8+121 = 129 rt triangle
d - 1+3 = 4 rt triangle

alex has 5 t-shirts in the drawer. 2 are white, and the rest are black. He will pick a t-shirt from the drawer without looking, and then without replacing it, will pick a second t-shirt without looking. What is the probability that he will pick a white t-shirt on his first pick and a black t-shirt on his second pick?
Answer:
24%
Step-by-step explanation:
Lets consider it.
2 are white, and 3 are black.
2/5 chance of him getting white, and 3/5 chance of him getting black
So he successfully gets white on his first try.
2/5
Then he successfully gets black on his second try
2/5 * 3/5, or 6/25, or 24% of him getting white, then black.
This is all just middle school math, and I hope it helps :)

5/8 - 2/32 =
Subtrahend: 2/32
[tex]\implies \dfrac{2}{32} \implies \dfrac{1 \times 2}{16 \times 2} \implies \underlin\dfrac{1}{16}[/tex]
2) Determine the LCM of the denominators.The LCM of the denominators in the subtraction problem (5/8 - 2/32) can be determined by writing the multiples of 16 (Simplified denominator) and 8.
Writing the multiples of the denominators (16 and 8):
Multiples of 16 ⇔ 16, 32, 48, 64, 80...Multiples of 8 ⇔ 8, 16, 24, 32, 40...Since we can see that 16 is a common multiple and is has the least value in both multiples, 16 is the common multiple of 8 and 16.
3) Solving the subtraction problem.Multiply such number to the denominators such that the denominators are equivalent to the LCM. Keep in mind that the number we multiply in the denominator must be multiplied to the numerator.
[tex]\implies \dfrac{5}{8} - \dfrac{1}{16}[/tex]
[tex]\implies \dfrac{5 \times x}{8 \times x} - \dfrac{1}{16} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ [8x = \text{LCM}][/tex]
[tex]\implies \dfrac{5 \times 2}{8 \times 2} - \dfrac{1}{16} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ [8 \times x = \text{LCM} \implies 8 \times x = 16 \implies x = 2][/tex]
[tex]\implies \dfrac{10}{16} - \dfrac{1}{16}[/tex]
[tex]\implies \dfrac{10}{16} - \dfrac{x}{16x} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ [16x = \text{LCM}][/tex]
[tex]\implies \dfrac{10}{16} - \dfrac{1 \times 1}{16 \times 1} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ [16 \times x = \text{LCM} \implies 16 \times x = 16 \implies x = 1][/tex]
[tex]\implies \dfrac{10}{16} - \dfrac{1}{16}[/tex]
Finally, let's subtract the fractions as the fractions have like denominators.
[tex]\implies \dfrac{9}{16}[/tex]
Therefore, the simplified fraction is 9/16.

List a specific example with a set and a subset.
Your example needs to be unique and in your own words.
Some examples:
The set of all animals in the world. A subset could be the group of all dogs. The set of all people in a country. A subset would be the group of people in a small town of that same country.Everything in a person's house (set), vs items located inside the person's kitchen only (subset).The set of parallelograms. A subset is the set of all squares.The set of rational numbers, in which the collection of integers is a subset.With each example, any item or person in the subset is also found in the original set (but not vice versa). For example, any dog is an animal but not the other way around.
If you were to draw a venn diagram, then the larger circle is the set of all animals, while the subset of all dogs is a smaller circle drawn completely inside the larger one.
Those examples listed above is of course not the complete list of set & subset combos. Feel free to get creative and think of others.
