The lithosphere is: a. the rigid outer part of the earth, consisting of the crust and upper mantle.
What is the Lithosphere?The Lithosphere is the solid outer shell of the Earth that forms the Earth's surface, including the continents and the ocean floor. It is the uppermost layer of the Earth's solid surface, composed mostly of the minerals, such as silicon and oxygen, that form rocks like granite and basalt.
The lithosphere is composed of the Earth's crust and the uppermost part of the Earth's mantle. It is broken up into tectonic plates that are in constant motion and are responsible for the earthquakes, volcanoes, and the creation and destruction of land masses. The lithosphere is also the layer that supports all life on Earth.

the sums of the measures of the interior angles of a polygon is three times the sum of its exterior angles. how many sides does it have. please help
The sums of the measures of the interior angles of a polygon is three times the sum of its exterior angles then it has 8 sides .
What is Polygon?
A polygon is a two-dimensional, closed form that is flat or planar and is limited by straight sides. Its sides are not curled. A polygon's edges are another name for its sides. The vertices (or corners) of a polygon are the places where two sides converge. Here are some illustrations of polygons.
What is interior angles?
Interior angles are those that are located within the confines of two parallel lines that are intersected by a transversal.
What is exterior angles?
The angles that are created outside of a triangle are its external angles. In other terms, the angle created between one of a triangle's sides and its neighboring extended side is the triangle's external angle.
We know that sum of interior angle of regular polygon is ;
(n-2) x 180°
Where n = no. of sides
We also know that sum of exterior angle of regular polygon is 360°.
The fact that the sum of a polygon's internal angles is three times the sum of its outside angles is now a given;
Therefore;
sum of interior angles of a regular polygon = 3 x sum of exterior angle
⇒ (n-2) x 180°
⇒3 x 360°
Simplify the equation we have above by:
⇒(n-2) = 3 x 360°/180° = 6
⇒ n = 6+2 = 8

The acceleration function (in m/s2) and the initial velocity are given for a particle moving along a line.
a(t) = t + 4, v(0) = 3, 0 ≤ t ≤ 11(a) Find the velocity at time t. 3 m/s (b) Find the distance traveled during the given time interval.
The distance traveled during the given time interval be 2024 m.
What is meant by acceleration function?An object's rate of change in velocity is referred to as its acceleration. The rate of change in velocity is known as acceleration. Acceleration typically signals a change in speed, though this is not always the case. Because of the shifting direction of its velocity, an item moving on a circular path at a constant speed is still accelerating.
By integrating the velocity v in terms of time t, v = gt, we can determine acceleration, which is the rate of change of velocity with respect to time.
Let the function be a(t) = t + 4
time = 11
substitute the value of t in the above equation, we get
a(11) = 11 + 6 = 17 m/s²
a = v/t, so v = at
finally v = (17 m/s²) (11s)
v = 187 m/s
b) Find the distance traveled during the given time interval
[tex]$$V_{total} = V_{final} - V_{ initial[/tex]
V final = 187 m/s, Vinitial = 3 m/s
V total = 187 - 3 = 184 m/s
Let the equation of velocity be
Velocity = distance/time
distance = velocity × time
distance = 184 m/s × 11 s
distance = 2024 m
Therefore, the distance traveled during the given time interval be 2024 m.

Airline passengers get heavier In response to the increasing weight of airline passengers, the Federal Aviation Administration (FAA) in 2003 told airlines to assume that passengers average 190 pounds in the summer, including clothes and carry-on baggage. But passengers vary, and the FAA did not specify a standard deviation. A reasonable standard deviation is 35 pounds. Weights are not Normally distributed, especially when the population includes both men and women, but they are not very non-Normal. A commuter plane carries 30 passengers.
• (a) Explain why you cannot calculate the probability that a randomly selected passenger weighs more than 200 pounds.
• (b) Find the probability that the total weight of the passengers on a full flight exceeds 6000 pounds. Show your work. (Hint: To apply the central limit theorem, restate the problem in terms of the mean weight.)
The probability that the total weight of the passengers on a full flight exceeds 6000 pounds is about 0.0147 or 1.47%.
What is the Central Limit Theorem?
The Central Limit Theorem states that the sum of a large number of independent and identically distributed random variables is approximately Normally distributed.
(a) The reason why you cannot calculate the probability that a randomly selected passenger weighs more than 200 pounds is that the weight of passengers is not Normally distributed.
The Normal distribution is a symmetric bell-shaped distribution that is defined by its mean and standard deviation.
The weight of passengers is not symmetric and it may not follow a bell shape.
Therefore, we cannot use the Normal distribution to calculate the probability of a weight greater than 200 pounds.
(b) To calculate the probability that the total weight of the passengers on a full flight exceeds 6000 pounds, we can use the Central Limit Theorem.
Since we don't know the exact distribution of the weight of the passengers, we can use the Central Limit Theorem to approximate the total weight of the passengers on a full flight.
The mean weight of a passenger is 190 pounds, and the standard deviation is 35 pounds. Since a full flight carries 30 passengers, the mean weight of the passengers on a full flight is 19030 = 5700 pounds and the standard deviation is 35sqrt(30) = 175 pounds.
To find the probability that the total weight of the passengers on a full flight exceeds 6000 pounds, we can use the standard normal distribution table.
z = (6000 - 5700) / 175 = 2.2857
Probability P(X > 6000) = P(Z > 2.2857) = 1 - P(Z < 2.2857) = 1 - 0.9853 = 0.0147
Hence, the probability that the total weight of the passengers on a full flight exceeds 6000 pounds is about 0.0147 or 1.47%.

In an interval whose length is z seconds, a body moves (32z + 2z^ 2 ) ft. What is the average speed v of the body in this interval?
The average speed of the body in the given interval is 32 + 2z ft/s.
The average speed v of a body in an interval of z seconds can be calculated using the formula v = d/t, where d is the distance traveled and t is the time taken.
In this case, the distance d is (32z + 2z^ 2 ) ft and the time taken is z seconds.
Therefore, the average speed v of the body in this interval is:
v = (32z + 2z^ 2 ) ft / zs
v = 32 + 2z ft/s

The equation of this parallel line is y = 4x - 22. Railroad tracks, sidewalk edges, ladder rails, endless rail tracks, opposing sides of a ruler, opposite edges of a pen, an eraser, and other real-world objects are instances of parallel lines.
What is meant by parallel line?In a plane, lines that are consistently spaced apart from one another are referred to as parallel. Parallel lines don't ever intersect. Perpendicular lines are those that intersect at a 90-degree angle.Parallel lines are two lines that are never crossed and are equally spaced apart from one another.They could be horizontal or vertical. Parallel lines can be found in our daily life in the form of nearby train tracks, rows of notebooks, and zebra crossings.Since there is no "b" in the conventional equation y = mx + b, the line y = 4x has a slope of 4 and an intercept of 0. Any parallel line will have the same slope as the slope (m = 4) in this case. The slope of all parallel lines will be the same.
So let's return to the conventional format and replace the m with a "4".
y = 4x + b
Now that the values have been entered into the equation, let's solve for "b" using the point that sits on the line.

What is polygon?Any closed curve that consists entirely of connected line segments (sides) without any intersections is known as a polygon in geometry. The three simplest polygons are pentagons, triangles with three sides, and quadrilaterals with four sides (five sides). The two types are concave and convex polygons.
Convex polygons are those without any extended sides crossing over them. Equilateral refers to a polygon with equal sides. Interior angles of equiangular shapes are equal. Every equilateral and equiangular polygon is a regular polygon (e.g., an equilateral triangle or a square).
As all sides are equal, all diagonals are equal too, and the angle of adjacent diagonals are 90° with vertical opposite angle.
Therefore,
Each side = [tex]\sqrt{\text {diagonal}^2+ \text {diagonal}^2}[/tex]
Each side = [tex]\sqrt{(6\sqrt{2} )^2+(6\sqrt{2} )^2}[/tex]
Each side = [tex]\sqrt{(36\times 2+36\times 2}[/tex]
Each side = [tex]\sqrt{144}[/tex]

Caitlyn needs to mail a USB drive to a friend. She uses 42 -cent stamps and 5 -cent stamps to pay $1.71 in postage. How many of each stamp did Caitlyn use?
Solving an equation we will see that Caitlyn used 3 of the 42-cent stamps and 9 of the 5-cent ones.
How many of each stamp does she use?Let's define the variables that we will be using:
x = number of 42-cent stapms.y = number of 5-cent stamps.Then the total value of the stamps, in dollars, is:
x*0.42 + y*0.5
And we know that the value must be $1.71, then we can write the equation:
x*0.42 + y*0.05 = 1.71
y = (1.71 - x*0.42)/0.05
To find the values of x and y, we can just evaluate in different whole values of x, until we get a whole value of y.
using x = 1 we get:
y = (1.71 - 0.42)/0.05 = 2.58
This is not a solution.
if x = 3
y = (1.71 - 0.42*3)/0.05 = 9

Cost of A1 = 4800
A1 was sold for a loss of 15%
Loss = 15% of 3640 = 0.15 x 3640 = Rs 546
A2 bought at 4800 was sold at a gain of 13 1/3%
Gain from sale = 13 1/3% of 4800 = 40/300 x 4800 =Rs 640
We have to treat gain as positive and loss as negative to arrive at the answer
Net gain/loss = 640 - 546 = Rs. 94
