Therefore, the volume of the truncated cuboid is approximately 68 + 4*√(30) cubic meters.
What is volume?Volume is a measure of the amount of space occupied by a three-dimensional object. It is the amount of three-dimensional space enclosed by the boundaries of an object. Volume is typically measured in cubic units, such as cubic meters (m³) or cubic centimeters (cm³).
Here,
The truncated cuboid is a solid figure that is obtained by cutting off the top of a rectangular prism (cuboid) with a plane that is parallel to the base. The formula for the volume of a truncated cuboid is:
V = h/3 * (A + √(A*B) + B)
where V is the volume, h is the height of the truncated portion, A is the area of the top face, and B is the area of the base face.
In this case, the height of the truncated portion is 3 m, the top face has an area of 5 m x 8 m = 40 m², and the base face has an area of 8 m x 1.5 m = 12 m². Therefore:
A + B = 40 + 12 = 52 m²
√(AB) = √(4012) = √(480) = 4*√(30)
Substituting these values into the formula, we get:
V = 3/3 * (52 + 4√(30) + 12)
V = 68 + 4√(30)

50 hombres tienen provisiones para 20 días a razón de tres raciones diarias. Sí las
raciones se disminuyen en 1/3 y se aumentan 10 hombres ¿Cuántos días durarán
los víveres?
Answer:
Para resolver este problema, primero debemos encontrar la cantidad total de raciones que tienen los 50 hombres para 20 días a razón de tres raciones diarias:
50 hombres x 3 raciones por día x 20 días = 3000 raciones
Esto significa que tienen un total de 3000 raciones de alimentos para los 50 hombres durante 20 días.
Luego, podemos calcular la cantidad de raciones diarias después de la disminución en 1/3:
3 raciones diarias - (1/3)(3 raciones diarias) = 2 raciones diarias
Esto significa que cada hombre ahora recibe 2 raciones diarias en lugar de 3.
Después de aumentar el número de hombres en 10, tenemos un total de 60 hombres:
50 hombres + 10 hombres = 60 hombres
Podemos calcular la cantidad total de raciones diarias para los 60 hombres durante los días que durarán las provisiones:
60 hombres x 2 raciones por día = 120 raciones diarias
Finalmente, podemos calcular la cantidad de días que durarán los víveres:
3000 raciones totales / 120 raciones diarias = 25 días
Por lo tanto, los víveres durarán 25 días después de disminuir las raciones en 1/3 y aumentar el número de hombres en 10.

As the Earth revolves around the sun, it travels at a speed of approximately 18 miles per second. Convert this speed to kilometers per second. At this speed, how many kilometers will the Earth travel in 10 seconds? In your computations, assume that 1 mile is equal to 1.6 kilometers. Do not round your answers.
Answer:
[tex]\frac{28.5km}{sec}[/tex]
In 10 seconds the earth will travel 288 km
Step-by-step explanation:
[tex]\frac{18miles}{sec}[/tex] x [tex]\frac{1.6km}{1 mile}[/tex] = [tex]\frac{28.8km}{sec}[/tex]
[tex]\frac{28.8km}{sec}[/tex] x [tex]\frac{10sec}{1}[/tex] = 288 km

Nakia is an architect designing a house with a peaked roof. She is trying to decide what the limitations are on her design. If AB is 8 feet and triangle ABC will be isosceles, describe the possible lengths for AC.
The possible calculated length of the segment AC is a length of any value that exceeds around 7.15 feet.
How to use Pythagoras Theorem?If triangle ABC is an isosceles triangle, then the length of AC must be equal to the length of BC.
Let's denote the length of AC as "x".
To find the length of the diagonal line segment referred to as BD, which represents the height of the peaked roof, we can use the Pythagorean theorem:
BD² = AB² - (AC/2)²
BD² = 8² - (x/2)²
BD² = 64 - x²/4
In order for the roof to be peaked, BD must be less than x, otherwise the roof would be flat.
Therefore, we can set up the inequality:
x√(64 - x²/4) < x
64 - x²/4 < x²
Multiplying both sides by 4 gives:
256 - x² < 4x²
5x² > 256
Dividing both sides by 5 gives:
x² > 51.2
x > √(51.2)
x > 7.15 feet
As a result, any value greater than the square root of 51.2 (approximately 7.15 feet) is a possible length for AC.

If the roof is to be peaked, then the length of segment BD must be less than x. Thus, we generate the inequality:
BD < x
√(64 - (x²/4)) < x
Square both sides to get:

Define Tautology?A compound statement known as a tautology is one that is true regardless of whether the individual statements inside it are true or false.
The Greek term "tautology," which means "same" and "logy," is where the word "tautology" comes from.
We need to build a truth-table and examine the truth value in the last column in order to determine whether a particular statement is a tautology.
It is a tautology if all of the values are true.
In the given case:
p is TRUE
and
q is FALSE
In this case:
p→q : is FALSE (the assumption “TRUE implies FALSE” is FALSE)
So, here:
p → (p→q) is equal to as p → FALSE
But p is TRUE so in that case it’s TRUE→ FALSE, which is in fact FALSE.
Since there a case where the expression is not true, then it’s not valid.

The measure of angle ABC is 40 degrees.
What is inscribed angle theorem ?
The inscribed angle theorem, also known as the central angle theorem, states that an angle inscribed in a circle is half the measure of the central angle that intercepts the same arc, or in other words, the angle that connects the endpoints of the arc.
In other words, if we draw a chord of a circle and an angle with its vertex on the circumference of the circle and its sides passing through the endpoints of the chord, then the measure of the inscribed angle is half the measure of the central angle that subtends the same arc as the inscribed angle.
According to the question:
By the inscribed angle theorem, the measure of an inscribed angle is half the measure of the arc it intercepts.
Since chord AB is congruent to chord CB, we can conclude that angle A is congruent to angle C, because they both intercept the same arc AC. Thus, we have:
angle BAC + angle ABC + angle ACB = 180 degrees (by the angle sum property of triangles
Substituting the measure of arc AC, we get:
angle BAC + angle ABC + 70 degrees = 180 degrees
Simplifying, we get:
angle BAC + angle ABC = 110 degrees
Since angles A and C are congruent, we have:
2 x angle BAC + angle ABC = 180 degrees
Substituting angle BAC + angle ABC = 110 degrees, we get:
2 x 110 degrees - angle ABC = 180 degrees
Solving for angle ABC, we get:
angle ABC = 40 degrees
Therefore, the measure of angle ABC is 40 degrees.

How does angle opposite to a side of triangle affect its size?
If the angle facing a side of a triangle increases, then the length of the opposite side may also increase. This is because the larger the angle, the more vertical the opposite side becomes, and therefore the longer it may become.
Conversely, if the angle facing a side of a triangle decreases, then the length of the opposite side may also decrease. This is because the smaller the angle, the less vertical the opposite side becomes, and therefore the shorter it may become.
From the given diagram, the largest side of the triangle will be the side directly opposite the largest angle.

What is the outcome and sample space of getting a sum of 9 when three dice are rolled
The outcome of getting a sum of 9 when three dice are rolled is that the sum of the three numbers shown on the dice must add up to 9. The sample space for this scenario can be written as S = { (1,3,5), (2,3,4), (2,4,3), (3,2,4), (3,4,2), (4,2,3), (4,3,2), (5,1,3)}
What is outcome?Outcome refers to the result of an action or event. It is the end result of the process and can be positive, negative, or a mix of both. Outcome can also refer to the impact of an event, such as the effect it has on the environment, the people affected, or the economy.
The sample space for this scenario is the set of all possible combinations of three dice that add up to 9.
Each of the elements in this set represents a combination of numbers on the dice that will add up to 9 when rolled. For example, the first element of this set (1,3,5) means that if the three dice are rolled, the numbers shown on the dice will be 1, 3, and 5, and the sum of the numbers will be 9.
When determining the sample space for the outcome of rolling three dice, the order of the numbers does not matter. Therefore, the sets (2,3,4) and (4,2,3) are equivalent, since the sum of the numbers is still 9 regardless of the order.
In conclusion, the outcome of getting a sum of 9 when three dice are rolled is that the sum of the three numbers shown on the dice must add up to 9. The sample space for this scenario is the set of all possible combinations of three dice that add up to 9.

Area = length x width
Substituting the given values, we get:
Area = 12 ft x 7 ft
Area = 84 square feet
To find the cost of the stain, we need to multiply the area of the porch by the cost per square foot:
Cost of stain = Area x Cost per square foot
Cost of stain = 84 square feet x $0.70/square foot
