r = 2
The volume of a cone can be found using the following equation
[tex]V = r^2\frac{h}{3} \pi[/tex]
After putting in the information that we already know we get
[tex]16\pi = r^2\frac{12}{3} \pi \\16\pi = r^2(4) \pi \\4 = r^2\\ r = 2\\[/tex]
For proof's sake, we can try the equation again with the information we know
[tex]V = r^2\frac{h}{3} \pi \\V = 2^2\frac{12}{3} \pi \\V =4(4) \pi \\V = 16\pi[/tex]
Pls I need help someone pls help me
The diameter of a sphere is multiplied by 1/5. What is the effect on the surface area?
Answer choices:
5 times bigger
5 times smaller
25 times bigger
25 times smaller
15 times bigger
15 times smaller
125 times bigger
125 times smaller
Answer is not here
Answer:
25 times smallerStep-by-step explanation:
Scale factor is:
k = 1/5Ratio of surface areas is:
k² = (1/5)² = 1/25Surface area will be 25 times smaller
Correct choice is D
We know the ratio of sides to area
a/b=a²/b²So
If diameter is multiplied by 1/5
Surface are increases
(1/5)²1/2525 times smaller

Which set of ordered pairs (x, y) could represent a linear function of x?? A ((-2,8), (0,4) , (2, 3) , (4,2)) B ((1,2), (1,3),(1,4), (1,5)) C ((-2,7) , (0,12),(2,17),(4,22)) D ((3,5), 4,7) , (3, 9) , (5,11))
Answer:
A linear function is when it goes up the same amount each time. The first one does because it increases by 2 each time, so A

Find the distance between the two points.
Answer:
[tex]\sqrt{61}[/tex]
Step-by-step explanation:
Calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (- 2,- 4) and (x₂, y₂ ) = (4, 1)
d = [tex]\sqrt{(4-(-2))^2+(1-(-4))^2}[/tex]
= [tex]\sqrt{(4+2)^2+(1+4)^2}[/tex]
= [tex]\sqrt{6^2+5^2}[/tex]
= [tex]\sqrt{36+25}[/tex]
= [tex]\sqrt{61}[/tex]

Answer:
x = 28
Step-by-step explanation:
AB= AC
∠B = ∠C {Angles opposite to equal sides are equal}
∠A + ∠B + ∠C = 180 {angle sum property}
3x + x + 20 + x + 20 = 180 {Combine like terms}
3x +x +x + 20 + 20 = 180
5x + 40 = 180 {subtract 40 from both sides}
5x = 180 - 40
5x = 140 {divide both sides by 5}
x = 140/5
x = 28

The tree diagram below illustrates the possible outcomes of three tosses of a balanced coin. What is the probability that “heads” will come up exactly two out of three times
please explain step by step
3/8 = 0.375 = 37.5%
====================================================
Explanation:
Start at the very left hand side of the diagram. Also, start at the top as well. So you'll start at "heads". Trace along the top most path and you'll get "heads, heads, heads". This says we got 3 heads in a row. But we want a case where heads only comes up exactly twice. So we rule out this scenario.
Go back to the first "heads". Now trace along the top, but don't land on that third "heads". Instead, go to the "tails" that is underneath in that last column. So you'll have "heads, heads, tails". This time we got exactly two heads out of three tosses. Off to the side somewhere, make a tally of how many times this scenario happens. Another time it happens is when we get "heads, tails, heads". Another time is when you get "tails, heads, heads".
There are only three situations where we get exactly two heads out of three tosses. This is equivalent to the event "getting exactly one tail", so that might be an easier scenario to track down.
If you traced out all of the possible paths, you would find that there are 8 different paths. Note how 2^3 = 2*2*2 = 8 is a numerical way to compute this, due to the fact that each coin toss has 2 outcomes and we have three tosses total.
Since we have three outcomes where we got exactly two heads, out of 8 outcomes total, this leads to the answer being 3/8
Side note: 3/8 = 0.375 = 37.5%
----------------------
We could also solve this problem by listing out all the possible scenarios. I'll use H for heads and T for tails. Something like HHT means we got heads twice in a row, then tails later. The order matters.
Listed below are the 8 possible outcomes. The items in bold represent situations where we get exactly two heads, which is the same as getting exactly one tail.
HHHHHTHTHHTTTHHTHTTTHTTTThe order of each of those eight items is the same as the order if you were to trace out the possible paths of the table given (starting at the top and moving down). We can see that there are 3 cases where we get exactly two 'H's out of 8 possible outcomes total. So that's another way to arrive at 3/8
The expression 6x - 4 represents the diameter of a circle. The radius is 16 inches. What is the value of x?
Answer: 6
Step-by-step explanation:
Firstly, it should be noted that the diameter of a circle is twice its radius. In this case, the diameter of the circle will be:
Diameter = Radius × 2
Diameter = 16 × 2 = 32 inches
Therefore, to solve for x goes thus:
6x - 4 = 32
6x = 32 + 4
6x = 36
x = 36/6
x = 6

Give your answer in its simplest form.
find the means 01023 234
Answer:
This is not really clear, I will assume that the values in the question are:
{0, 1, 0, 2, 3, 2, 3, 4}
For a set of N elements, {x₁, x₂, ..., xₙ}
The mean of the set is given by:
[tex]Mean = \frac{x_1 + x_2 + ... + x_n}{N}[/tex]
In the case of our set, {0, 1, 0, 2, 3, 2, 3, 4}, we have 8 values.
Then the mean of our set is:
[tex]Mean = \frac{0 + 1 + 0 + 2+ 3 + 2 + 3 + 4}{8} = \frac{15}{8} = 1.875[/tex]

Answer:
75 sq units
Step-by-step explanation:
A = lw
l = OP = distance between (9, 6) and (0, -6)
= [tex]\sqrt{(9 - 0)^{2} + (6 + 6)^{2} }[/tex]
= [tex]\sqrt{81 + 144)} = \sqrt{225} = 15[/tex]
w = MP = distance between (-4, -3) and (0, -6)
= [tex]\sqrt{(-4 - 0)^{2} + (-3 + 6)^{2} }[/tex]
= [tex]\sqrt{16 + 9} = \sqrt{25} = 5[/tex]
A = 15(5) = 75 sq units
Help 15 points for the answer
Answer:
3x² + 7x + 6
Step-by-step explanation:
Big Rectangle:
A = bh
A = (x + 3)(x + 2)
A = x² + 2x + 3x + 6
A = x² + 5x + 6
Small rectangle:
A = bh
A = (x + 1)(2x)
A = 2x² + 2x
Combined:
x² + 5x + 6 + 2x² + 2x
3x² + 7x + 6
