To find the surface area of the composite figure, we need to break it down into simpler shapes and add up their surface areas. From the given dimensions, we can see that the composite figure consists of two rectangular prisms and a triangular prism.
The dimensions of the rectangular prism are 10 cm (length), 8 cm (width), and 24 cm (height). Therefore, its surface area is:
SA1 = 2lw + 2lh + 2wh
SA1 = 2(10 cm)(8 cm) + 2(10 cm)(24 cm) + 2(8 cm)(24 cm)
SA1 = 160 cm^2 + 480 cm^2 + 384 cm^2
SA1 = 1024 cm^2
The dimensions of the triangular prism are 5 cm (base), 12 cm (height), and 8 cm (length). Therefore, its surface area is:
SA2 = lb + 2[(1/2)bh + lh]
SA2 = (8 cm)(5 cm) + 2[(1/2)(5 cm)(12 cm) + (8 cm)(12 cm)]
SA2 = 40 cm^2 + 240 cm^2 + 96 cm^2
SA2 = 376 cm^2
The dimensions of the rectangular prism on top are 4 cm (length), 5 cm (width), and 12 cm (height). Therefore, its surface area is:
SA3 = 2lw + 2lh + 2wh
SA3 = 2(4 cm)(5 cm) + 2(4 cm)(12 cm) + 2(5 cm)(12 cm)
SA3 = 40 cm^2 + 96 cm^2 + 120 cm^2
SA3 = 256 cm^2
To find the total surface area of the composite figure, we add the surface areas of the three shapes:
Total surface area = SA1 + SA2 + SA3
Total surface area = 1024 cm^2 + 376 cm^2 + 256 cm^2
Total surface area = 1656 cm^2
Therefore, the surface area of the composite figure is 1656 cm^2.

The area of the given figure will be 145.13 m².
The area of a rectangle is calculated as length multiplied by width, while the area of a semi-circle is half the area of a circle with the same radius. We can calculate the combined area of the rectangle and semi-circle as follows:
Area of rectangle = length x width = 15 m x 8 m = 120 m^2
Area of semi-circle = 1/2 x pi x radius^2 = 1/2 x pi x 4^2 = 8 pi m^2
To find the total combined area, we add the area of the rectangle to the area of the semi-circle:
Total combined area = Area of rectangle + Area of the semi-circle
= 120 m² + 8π m²
= 120 m² + 25.13 m² (using π= 3.14159)
= 145.13 m
Therefore, the combined area of the rectangle and semi-circle is 145.13 square meters (rounded to two decimal places).

Suppose triangle has sides a, b, and c and that a^2+b^2
The options that are true with respect to the lengths of the sides of the triangle and the included angle between sides a and b are;
The triangle is not a right triangle
cos(θ) < 0
The angle θ is an obtuse angle
What is a triangle?A triangle is a polygon that has three sides and three interior angles.
The specified sides of the triangle are; a, b, and c
The relationship between the squares of the lengths of the sides, obtained from a similar question is presented as follows; a² + b² < c²
The specified measure of the angle opposite the side c = θ
According to Pythagorean Theorem, a triangle is a right triangle, if in the triangle, we can get; a² + b² = c²
The specified inequality, relating the squares of the lengths of the sides, a² + b² < c², which therefore, indicates;
The triangle is not a right triangle.According to cosine rule, we get;
c² = a² + b² - 2·a·b·cos(θ)
However; a² + b² < c²
c² - (a² + b²) = -2·a·b·cos(θ)
a² + b² < c²
0 < c² - (a² + b²)
0 < c² - (a² + b²) = -2·a·b·cos(θ)
0 < -2·a·b·cos(θ)
Dividing both sides by -1, the inequality sign is reversed, and we get;
0/(-1) > -2·a·b·cos(θ)/(-1) = 2·a·b·cos(θ)
0 > 2·a·b·cos(θ)
Therefore; 2·a·b·cos(θ) < 0
2·a·b·cos(θ)/(2·a·b) = cos(θ) < 0/(2·a·b) = 0
cos(θ) < 0cos(θ) is therefore, negative, which indicates that θ is in the second quadrant, with the solution, obtained using an online tool which can be expressed as follows;
(π/2) + 2·π·n < θ < (3·π/2) + 2·π·n
Where n = 0, we get;
(π/2) < θ < (3·π/2); The angle θ is therefore larger than π/2 = 90° and less than (3·π/2) = 270°, which in a triangle the maximum angle is 180°, indicating that the angle θ is an obtuse angle.

if the range of feasibility indicates that the original amount of a resource, which was 20, can increase by 5, then the amount of the resource can increase to 25. T/F
If the range of feasibility indicates that the original amount of a resource, which was 20, can increase by 5, then the amount of the resource can increase to 25. The statement is true.
If the range of feasibility for a given resource indicates that the original amount can increase by 5, that means the upper limit of the feasible range is 20 + 5 = 25. Therefore, the amount of the resource can increase up to 25, which is the upper bound of the feasible range.
However, it's important to note that just because the resource can increase up to 25 doesn't mean it will actually reach that level. The feasibility range only indicates what is possible or allowable based on certain criteria or constraints. Whether the resource actually increases to that level will depend on various factors such as availability, demand, and cost.
In summary, if the range of feasibility for a resource indicates an increase of 5 from an original amount of 20, then the amount of the resource can increase up to 25, but the actual increase will depend on other factors.

The Nutrition Facts tell us that one serving (2 Kind bars) accounts for 17% of a person’s daily intake of fat for a 2,000 calorie diet. How did they get that number; in other words, how did they calculate that number? Hint: Use the information at the bottom of the label and that “total” fat for daily intake vs “total” fat of Kind bars.
So, one serving of Kind bars, which is two bars, contributes for roughly 13.8% of a 2,000 calorie diet's daily fat consumption.
What is equation?An equation is a mathematical statement that shows that two expressions are equal. Equations can be used to represent relationships between variables, or to solve problems. Equations use mathematical symbols, such as the equal sign (=), to show the equality between the two expressions. For example, the equation 2x + 3 = 7 represents the relationship between the variable x and the constants 2 and 3. The equation can be solved for x to find its value. In this case, solving for x would give us x = 2.
Here,
The calculation for determining the percentage of daily fat intake in a serving of Kind bars is based on the Recommended Dietary Allowance (RDA) for fat. The RDA is a guideline for the average daily amount of a nutrient that is considered sufficient to meet the needs of most people.
For a 2,000 calorie diet, the RDA for total fat is about 65 grams per day. To calculate the percentage of daily fat intake in a serving of Kind bars, you divide the total amount of fat in the serving by the RDA for daily fat and multiply by 100.
For example, if one serving of Kind bars contains 9 grams of fat, you would perform the following calculation:
9 grams fat ÷ 65 grams RDA for daily fat x 100 = 13.8% daily fat intake
So, one serving of Kind bars, which is two bars, accounts for approximately 13.8% of a person's daily fat intake for a 2,000 calorie diet.

Using Heron's formula, show that the equilateral triangle has the maximum area for any fixed perimeter. Hint: In xyz≤k.

Heron's formula states that the area of a triangle can be found using the following formula:[tex]A = √s(s-a)(s-b)(s-c)[/tex] where s is the semiperimeter of the triangle [tex](s = (a + b + c)/2)[/tex].
In the case of an equilateral triangle, all three sides (a, b, and c) are the same length. So, if we set x = y = z in the formula, we get [tex]A = √s(s-x)(s-x)(s-x).[/tex] Simplifying this expression yields [tex]A = (√s/4) * x^2[/tex].
We can also write the perimeter of the triangle as P = 3x. Substituting this into the area formula, we get [tex]A = [(P/3)*√3/4] * (P/3)^2[/tex]. This expression can be simplified to [tex]A = (1/12) * P^2 * √3.[/tex]
This shows that for a fixed perimeter, the area of an equilateral triangle is maximized. This is due to the fact that the area is proportional to the square of the sides, and in an equilateral triangle all sides are equal, thus maximizing the area. Heron's formula states that the area of a triangle can be found using the following formula: A = √s(s-a)(s-b)(s-c) where s is the semiperimeter of the triangle (s = (a + b + c)/2).

The population size varies in several ways. The sample size was insufficient, which is the best explanation for why the simulation of the sampling distribution is not roughly normal.
A person's or a researcher's choice of sample size will limit the study's statistical power if it is too small or inadequate for the alpha level and the analyses they have decided to do.
Because of the aforementioned, it is much harder to determine from one's sample whether a statistical effect is existent in the population.

leaked out in the first hour. the first hour, What percent of the remaining water leaked
out in the second hour?
Using percentages we know that the water that will drain in the 2nd hour will be 25% of the remaining water.
What are percentages?A % is a quantity or ratio that, in mathematics, represents a portion of one hundred.
A dimensionless relationship between two numbers can be represented in a variety of ways, such as through ratios, fractions, and decimals.
The symbol "%" is frequently written after the number to indicate percentages.
Convert both percentages to fractions of 100 or decimals, multiply them, then use the result to calculate the percentage of the %.
Calculating 50% of 40%, for instance, yields (50/100) x (40/100) = 0.50 x 0.40 = 0.20, which equals 20/100 or 20%.
NOTE: Using the percent sign and a division by 100 at the same time is improper.
So, in the first hour:
The drained water is 20%.
Remaining left: 80%
Then, 20% of 80 would be:

the sum of the digits of a certain two-digit number is7. reversing its digits increase the number by 9. what is the number?
Answer: the number is 12.
Step-by-step explanation:
Let's call the two-digit number "x". We know that the sum of its digits is 7, so we can represent the number as 10a + b, where a and b are the digits of the number and a is the tens digit and b is the units digit.
The statement that "reversing its digits increases the number by 9" means that the number obtained by reversing the digits is x + 9. We can represent this reversed number as 10b + a.
So, we have two equations:
10a + b = x
10b + a = x + 9
Now, we can substitute the value of x from the first equation into the second equation:
10b + a = 10a + b + 9
Expanding both sides, we get:
10b + a = 10a + b + 9
9b = 9a + 9
b = a + 1
We know that 0 < a < 9, since the number is a two-digit number. So, we can conclude that 0 < b < 10.
We can now substitute the value of b into the first equation:
10a + (a + 1) = x
11a + 1 = x
11a = x - 1
a = (x - 1) / 11
Since a is the tens digit of the number, it must be an integer. We can test different values of x to find the value that satisfies this condition.
If x = 20, then a = (20 - 1) / 11 = 1. This gives us b = a + 1 = 2. The original number is 10a + b = 10 + 2 = 12, which satisfies all the conditions.
So, the number is 12.

im stuck on this question
w = amount of wagon stamps
b = amount of sailboat stamps
so hmm we know Megan bought 4 stamps, so whatever "w" and "b" are, we know that w + b = 4.
we also know that Megan spent 16 cents on all, and that the wagon ones cost 1c, so for "w" amount that's a total of 1*w or 1w. Now, the sailboat stamps cost 5c, that will give us a total of 5*b or 5b for those.
[tex]w+b=4\implies b=4-w \\\\[-0.35em] ~\dotfill\\\\ 1w+5b=16\implies \stackrel{\textit{substituting from the 1st equation}}{1w+5(4-w)=16} \implies w+20-5w=16 \\\\\\ 20-4w=16\implies 20=4w+16\implies 4=4w\implies \cfrac{4}{4}=w\implies \boxed{1=w} \\\\\\ \stackrel{\textit{since we know that}}{b=4-w}\implies b=4-1\implies \boxed{b=3}[/tex]
