Step-by-step explanation:
Changes in air pressure are determined by a variety of forces, including the density and temperature of air masses. When air moves from between areas of high pressure and low pressure, wind directions and speeds may change. The driving force behind changes in air pressure and therefore the creation of wind is gravity.

$4000.00 investment. Over 3 years $1080.00 interest accumulated. What was the interest on the loan? The interest is shown in percent as the answer.
Answer:
9% interest rate
Step-by-step explanation:
Investment = principal = $4000
Interest amount = $1080
Period, t = 3 years
Simple interest = principal * rate * time
1080 = 4000 * rate * 3
1080 = 12000 * rate
Rate = 1080 / 12000
Rate = 0.09
The rate as a percentage = 0.09 * 100% = 9%
Select the correct answer.A wooden board that is 108 inches long is cut into two equal parts. What is the length of each part in feet
4.5 is the length of each part in feet. This can be solved by using the concept of feet.
What is feet?foot, plural feet, any of a wide range of ancient, medieval, and modern linear measurements (often 25 to 34 cm) based on the length of the human foot and used only in English-speaking nations, where it typically consists of 12 inches or one-third yard.
The foot measured [tex]11^{\frac{1}{42}[/tex] inches in antiquity. The typical man's foot measures 12 inches in length nowadays.
Given that:
The length of the wooden board is given as = 108 inches.
As it is cut in 2 equal parts, it becomes: 108/2 = 54 inches in each
We have to calculate the length of each part in feet, so divide 54 by 12.
As we know,
12 inches = 1 feet
Thus, 54 inches = 54/12 feet = 4.5 feet
So, the length of each part is 4.5 feet.

What is the slope of this line? (5 points)
Show all work.
Slope of the line AB is 7/6.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
From the given graph the coordinates of A are (4, 3) and B is (-2, -4)
Slope AB=-4-3/-2-4
=-7/-6
Slope=7/6
Hence, slope of the line AB is 7/6.

Denise's cell phone plan is $29.95 per month plus $0.10 per minute of call time. Denise's
cell phone bill is $99.95. For how many minutes was she billed?
Answer:
700 minutes
Step-by-step explanation:
Let y represent the cost and x represent the number of minutes of call time
We have the equation
99.95 = 0.10x + 29.95
Now let's solve
99.95 = 0.10x + 29.95
70 = 0.10x
x = 700 minutes
So, she was billed for 700 minutes

What are the 3 different polynomial equation?
The 3 different polynomial equations are linear polynomial equations, quadratic polynomial equations, and cubic polynomial equations.
A polynomial equation is one where a polynomial is set equal to zero. i.e., it is an equation created with variables, non-negative integer exponents, and coefficients together with operations and an equal sign.
A polynomial equation is always like "polynomial = 0". Algebraically, it is of the form p(x) = aₙ xⁿ + aₙ₋₁ xⁿ⁻¹ + ... + a₁ x¹ + a₀x⁰ = 0, where
aₙ, aₙ₋₁, ...., a₁, a₀ are coefficients and all these numbers are real numbers.
'x' is the variable.
p(x) means "polynomial in terms of variable x"
'n' is a non-negative integer, it is the degree of p(x).

Need help with this, finding the length of the third side
Answer:
its sqrt (50)
Step-by-step explanation:
The triangle has a right angle, therefore we can use the Pythagorean theorem to find the hypotenuse. According to the theorem the sum of the squares of both other sides is equal to the square of the hypotenuse.
We have 5^2+5^2=c^2
=> 25+25=c^2
=> 50=c^2
Therefore c or the missing side is equal to sqrt(50)

Answer:
D
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{1}{3}[/tex] x - 2 ← is in slope- intercept form
with slope m = [tex]\frac{1}{3}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{3} }[/tex] = - 3 , then
y = - 3x + c ← is the partial equation
To find c substitute (4, - 7) into the partial equation
- 7 = - 12 + c ⇒ c = - 7 + 12 = 5
y = - 3x + 5 → D

Alice is playing a game in which she will roll 4 6-sided dice at the same time. She gets 5 points for each die that shows an even result. Let x represent the total number of points awarded on any given toss of the dice. What is the expected value of x? A. 1/2 B. 2 C. 10 D. 15 E. 20
The number of points is simply 5 times this random variable, and E(C*Y) = C*E(Y), where C is a constant and Y is a random variable, according to expected value principles. As a result, E(X) = 5*2 = 10.
What is probability?The field of mathematics concerned with probability is known as probability theory. Although there are various distinct interpretations of probability, probability theory approaches the idea rigorously mathematically by articulating it through a set of axioms. A probability is a number that represents the possibility or chance that a specific event will occur. Probabilities can be stated as proportions ranging from 0 to 1, as well as percentages ranging from 0% to 100%.
Here,
The number of dice that are showing an even number is a binomial random variable with n = 4, and p = 1/2 (because half the faces on the die are even and half are odd).
The expected value of this random variable is n*p = 4*1/2 = 2.
The number of points is simply 5 times this random variable, and by the rules of expected value, E(C*Y) = C*E(Y), where C is a constant and Y is a random variable. Thus E(X) = 5*2 = 10.

A chord of a circle is perpendicular to a radius at the midpoint of the radius. The ratio of the area of the larger of the two regions into which the chord divides the circle to the smaller can be expressed in the form \frac{a\pi+b\sqrt{c}}{d\pi-e\sqrt{f}}, where a, b, c, d, e, and f are positive integers, a and e are relatively prime, and neither c nor f is divisible by the square of any prime. Find the remainder when the product abcdef is divided by 1000.
The remainder when 2 is divided by 1000 is 2
Let O be the center of the circle, R be the length of the radius, and let the chord be AB with midpoint M. Let x be the distance from O to M, then the length of the radius OM is R/2 and the length of the chord AB is 2x.
Since the chord is perpendicular to the radius at the midpoint, we know that the radius bisects the chord. Therefore, the two segments MO and MB are congruent and have length x.
The area of the larger region is the area of the sector OMB, which is (1/4) of the area of the circle. The area of the smaller region is the area of the triangle OMA, which is (1/2) of the area of the sector OMA.
The ratio of the larger region to the smaller region is (1/4) : (1/2) = 2 : 1.
So, the area of the larger region is twice the area of the smaller region.
We can see that abcdef = 21111*1 = 2, the remainder when 2 is divided by 1000 is 2. Thus, the answer is \boxed{002}.
