Work out the density of the statue.
Give your answer to 2 d.p.
In the given situation with the help of the given mass and volume, the density is 9.45 g/cm³ respectively.
What do we mean by density?Mass per unit volume is the definition of a material's density.
In essence, density is a measurement of how closely stuff is packed.
It is a particular physical characteristic of a specific thing.
The Greek scientist Archimedes made the discovery of the density principle.
We can travel through low-density materials like air, which has a density significantly lower than that of human tissue.
Granite is a different material altogether.
Never attempt to traverse stone.
So, we have:
Volume: 38 cm
Mass: 359.1 g
Now, the density:
D = m/v
Insert values as follows:
D = m/v
D = 359.1/38
D = 9.45 g/cm³
Therefore, in the given situation with the help of the given mass and volume, the density is 9.45 g/cm³ respectively.

a triangular prism has a volume of 27.36 cubic units.the prism is 2.88units tall. what is the area of the triangular base
The area of the triangular base of the prism is 9.5 unit².
What is an area?
To find the area of the triangular base, we need to use the formula for the volume of a triangular prism:
V = (1/2)×b×h×H
Where b is the length of the base of the triangle, h is the height of the triangle, and H is the height of the prism.
We know that the volume of the prism is 27.36 unit³ and the height of the prism is 2.88 units. So we can plug these values into the formula:
27.36 = 1/2×b×h×2.88
Simplifying this equation, we get:
b×h = 19
We don't know the values of b and h separately, but we can use the fact that the area of a triangle is equal to (1/2)×b×h. So we can rewrite the equation as:
2 × (Area of triangular base) = 19
Dividing both sides by 2, we get:
Area of triangular base = 9.5 units²
Therefore, the area of the triangular base of the prism is 9.5 unit².

PLS ANSWER! THIS WAS DUE SO ON MARCH 27TH AND THIS IS ONE OF THEM!
Answer:
444 in
Hope this helps!
Step-by-step explanation:
Area of a triangle is [tex]\frac{1}{2}[/tex] × B × H
Already given, the base is 12 and the height is 12.5, [tex]\frac{1}{2}[/tex] and 12 can simplify to get 6 so 6 × 12.5 is 75. One triangle has the area of 75, the 4 triangles have a total area of 300.
The base is a square, so the formula for that is L × W, which would be 12 × 12 = 144. Add that to 300 and the surface area of the pyramid is 444.
G is the incenter of ABC
GD:
BG:
FC:
BF:
For the given triangle when G is the incenter of ABC the value of DG = 12, FC = 35, BG = 13.41, BF = 6.
What is incenter?The intersection of all three of the triangle's interior angle bisectors is where a triangle's incenter is located. It may be thought of as the intersection of the triangle's internal angle bisectors. Due to the junction point of the central axis being the centre of the triangle's inscribed circle, this point will be equally spaced from each of the triangle's sides.
The centre of a triangle's inscribed circle, which is the biggest circle that can fit within the triangle, is known as the incenter.
Given that, G is the incenter of the triangle.
Thus, EG = GF = DG.
Now, the value of DG is determined using the Pythagoras Theorem:
(37)² = DG² + (35)²
1369 = DG² + 1225
DG = 12
Now, FC = 35.
For, BG we have:
BG² = 6² + 12²
BG² = 36 + 144
BG = 13.41
BF = 6
Hence, for the given triangle when G is the incenter of ABC the value of DG = 12, FC = 35, BG = 13.41, BF = 6.

Problems 15 & 16. Determine whether the triangles are similar by AA~, SSS~, SAS~, or not similar. If the triangles are similar, write a valid similarity statement.
Part A : From Angle Angle similarity, ΔMBR and ΔZLP are similar.
Part B.: As the ratios of sides are not equal, triangles are not similar.
Explain about the similar triangles:Congruent triangles and similar triangles are two different but closely related concepts. Similar triangles are any two or more triangles having the identical proportions of their corresponding sides, an equal pair of corresponding angles, and their similar shape.
Part A:
using the equal sides property of triangle:
In ΔRBM,
side BM = side RM
So,
angle B = angle R (eq 1)
In triangle ZLP and PL = LZ
So, angle P = angle Z (eq 2)
And angle B = angle P
∠B = ∠R = ∠P = ∠Z
By Angle Angle similarity, triangle RBM and triangle ZLP are similar.
Part 16.:
In right angle triangle: KLN.
(KL)² = LN² + KN²
(KL)² = 8² + 15²
(KL)² = 64 + 225
(KL)² = 289
(KL) = 17

There are 8,246 registered to vote in the town of mayfield. About how many people voted in the election? Explain(there are 74 voters)
We can estimate that about 74 people voted in the election, which is the same as the actual number of voters.
What are the voters?
To estimate the number of people who voted in the election, we can use the proportion of registered voters who actually voted.
If we know that there are 8,246 registered voters in the town of Mayfield and 74 voters cast their vote, we can calculate the proportion of registered voters who voted as follows:
Proportion of voters = Number of voters / Number of registered voters
Proportion of voters = 74 / 8,246
Proportion of voters = 0.00897
We can then use this proportion to estimate the number of people who voted by multiplying it by the total number of registered voters:
Estimated number of voters = Proportion of voters x Number of registered voters
Estimated number of voters = 0.00897 x 8,246
Estimated number of voters = 73.9 (rounded to the nearest whole number)
Therefore, we can estimate that about 74 people voted in the election, which is the same as the actual number of voters.

Which statement about f(x) = -x squared + 8x-7 is true?
Option D : The statement that is true about the quadratic function f(x)=-x²+8x-7, which states that the zeros are 1 and 7, because f(x) = -(x - 1)(x - 7).
To find the zeros of the quadratic function f(x) = [tex]-x^2 + 8x - 7[/tex], we need to set f(x) equal to zero and solve for x:
[tex]-x^2 + 8x - 7 = 0[/tex]
We can solve this quadratic equation using the quadratic formula or by factoring. Let's use factoring.
We can rewrite the quadratic expression as:
[tex]-(x^2 - 8x + 7)[/tex]
To factor the expression, we need to find two numbers whose product is 7 and whose sum is -8. These numbers are -1 and -7. Therefore, we can rewrite the expression as:
-(x - 1)(x - 7)
So the zeros of the function are x = 1 and x = 7.

Burger Quick, because it has a smaller IQR
Burger Quick, because it has a smaller range
Super Fast Food, because it has a smaller IQR
Super Fast Food, because it has a smaller range
Burger Quick is able to estimate their wait time more consistently because it has a smaller IQR (Interquartile Range).
What is an IQR?
The IQR represents the range of the middle 50% of the data, and is a measure of the spread of the data. A smaller IQR indicates that the data is less spread out and more consistent. Therefore, since Burger Quick has a smaller IQR than Super Fast Food, it is able to estimate their wait time more consistently.
It is calculated by finding the difference between the third quartile (Q3) and the first quartile (Q1) of a dataset. The quartiles are values that split the data into four equal parts: Q1 represents the 25th percentile, Q2 (also known as the median) represents the 50th percentile, and Q3 represents the 75th percentile. The IQR therefore represents the range of the middle 50% of the data.
The IQR is a useful measure of variability because it is less sensitive to outliers than the range or standard deviation, which can be skewed by extreme values in the data. The IQR is often used in box plots to show the spread of the data and identify potential outliers.
What is Burger Quick?

Mrs. Harper is teaching a 5th grade class. She is
standing 6 meters in front of Annie. Javier is
sitting to Annie's right. If Javier and Mrs. Harper
are 8 meters apart, how far apart are Annie and
Javier? If necessary, round to the nearest tenth.
This is a Pythagorean theorem word problem
Answer:
Annie and Javier are 10 meters apart.
Step-by-step explanation:
We can use the Pythagorean theorem to solve this problem. Let's call the distance between Annie and Javier "x". Then, we have two right triangles:
The first right triangle is formed by Mrs. Harper, Annie, and the distance between Mrs. Harper and Annie. We know that Mrs. Harper is 6 meters in front of Annie, so the hypotenuse of this triangle is 6 meters.
The second right triangle is formed by Mrs. Harper, Javier, and the distance between Mrs. Harper and Javier. We know that Mrs. Harper and Javier are 8 meters apart, so the hypotenuse of this triangle is 8 meters.
Since Mrs. Harper is the common point of both triangles, we can combine them to form a larger right triangle with sides of 6 meters, 8 meters, and x meters:
Using the Pythagorean theorem, we have:
6^2 + 8^2 = x^2
Simplifying:
36 + 64 = x^2
100 = x^2
Taking the square root of both sides:
x = 10
Therefore, Annie and Javier are 10 meters apart.

P = (n / 100) × x
where P is the desired percentile (30th percentile in this case),
n is the total number of data points,
And x is the rank of the value corresponding to the desired percentile.
Here,
The total number of data points n = 20
x = (30 / 100) × 20
= 6.

To find the minimum value of a quadratic function most efficiently, we would like to see the quadratic function in its vertex form.
How to solveThe vertex form of a quadratic function is given by:
f(x) = a(x - h)^2 + k
where (h, k) is the vertex of the parabola, and "a" determines the direction and the "stretch" of the parabola.
If a > 0, the parabola opens upwards, and if a < 0, the parabola opens downwards.
The minimum value of the function occurs at the vertex if the parabola opens upwards (a > 0), and the maximum value occurs at the vertex if the parabola opens downwards (a < 0).
In this case, since we're looking for the minimum value, we would want a quadratic function where a > 0. Once we have the vertex form, we can easily identify the vertex (h, k), and the minimum value of the function will be k.

Answer:
Yes, the triangle with side lengths 6, 8, and 10 is a right triangle.
Explaination:
We can use the Pythagorean theorem to check if a triangle is a right triangle or not. According to the Pythagorean theorem, in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side (the hypotenuse). In other words:
a^2 + b^2 = c^2
where a and b are the lengths of the two shorter sides, and c is the length of the longest side (the hypotenuse).
In this case, the two shorter sides are 6 and 8, and the longest side (the hypotenuse) is 10. So we can plug these values into the equation above:
6^2 + 8^2 = 10^2
Simplifying:
36 + 64 = 100
100 = 100
Since the equation is true, this means that the triangle satisfies the Pythagorean theorem, and therefore it is a right triangle.

Yes 10 people would be unusual as it falls outside of 2 standard deviation of mean.
Here, the mean number of the famous brand name is 4.80000019, and the standard deviation is 0.73
so, μ = 4.80000019 and σ = 0.73
the number of people = 10
⇒ n = 10
Consider μ ± 2σ
= 4.80000019 ± 2(0.73)
= 4.80000019 ± 1.46
= [4.80000019 - 1.46, 4.80000019 + 1.46]
= [3.34000019, 6.26000019]
As we know 6.26000019 < 8
