If a cave explorer is at an elevation of −32 feet and the explorer starts moving at a rate of −6 feet per minute. it will take, 9 in minutes for the explorer to reach an elevation deeper than −140 feet.

Elevation of feet =  −32 feet.

Feet per minute =  −6 feet per minute

Elevation deeper than  feet = −140 feet

Let x  represent the time for reach the desired height

Inequality

-32 - 6x = ≤ -140

Substract 32 from both side

12x ≤ 140 -32

12x  ≤ 108

Divide both side by 12x

x ≤ 108/12

x ≤ 9

Therefore we can conclude that the explorer will have to use 9 minutes to get to the elevation.

The price of an adult ticket and a student ticket is $14 and $8, respectively.

Using algebraic expression and equation, we can express each statement and determine the price of each ticket.

Let x = the price of an adult ticket

y = the price of a student ticket

If on the first day of ticket sales, the school sold 3 student tickets and 1 adult ticket for a total of $38, then we can express this as:

3y + x = 38     (equation 1)

If the school took in $52 on the second day by selling 3 student tickets and 2 adult tickets, then we can express this as:

3y + 2x = 52     (equation 2)

3y + 2x = 52     (equation 2)

-(3y + x = 38)    (equation 1)

x = 14

Substitute the value of x in any of the two equations.

3y + x = 38     (equation 1)

3y + 14 = 38

3y = 38 - 14

3y = 24

y = 8

price of an adult ticket = $14

price of a student ticket = $8

Step-by-step explanation:

Move the decimal point one place to the right

The parameters are ΔUVW with side UW extended to X then m ∠UVW = (3x + 4)°, m ∠VWX = (8x -12)° and m ∠WUV = (x + 20)° then the value of x = 9°.

The given parameters exist;

ΔUVW with side UW extended to X

m ∠UVW = (3x + 4)°, m ∠VWX = (8x -12)° and m ∠WUV = (x + 20)°

We have that m ∠UVW + m ∠WUV + m ∠VWU = 180° (Sum of the interior angles of a triangle theorem)

Therefore, m ∠VWU = 180° - (m ∠UVW + m ∠WUV)

Also, we have that m ∠VWX and m ∠VWU exist supplementary angles, (The sum of angles on a straight line)

∴ m ∠VWX + m ∠VWU = 180° (Definition of supplementary angles)

m ∠VWU = 180° - m ∠VWX

∴ m ∠VWX = (m ∠UVW + m ∠WUV)

Substituting the values in the above equation, we get;

(8x -12)° = (3x + 4)° + (x + 20)°

simplifying the above equation, we get

8x - 3x - x = 4 + 20 + 12

4x = 36

x = 36/4 = 9

Therefore, the value of x = 9°.

Value of x is 28.5 and y is 14.

An angle is a figure in Euclidean geometry made up of two rays that share a terminal and are referred to as the angle's sides and vertices, respectively. Angles created when two rays are in the plane where the rays are located. The intersection of two planes also creates angles. We refer to these as dihedral angles.

Given Data

a = 2x + 3y

b = 4x - y

c = 3x + 2y

∠b = 100° ( corresponding angle)

4x - y = 100

4x - 100 = y

∠a = ∠b ( alternate angle)

2x + 3y = 4x - y

Equating values of y

2x + 3(4x - 100) = 4x - 4x + 100

2x + 12x - 300 = 100

14x = 400

AOB is a straight angle = 180°

the 3 angles on it therefore sum to 180° , that is

36 + 90 + 2x = 180

126 + 2x = 180 ( subtract 126 from both sides )

2x = 54 ( divide both sides by 2 )

x = 27

Answer:60°

Step-by-step explanation:the whole thing equals 180° since it is a straight line. 30°+90°=120°   180°-120°=60°

In 1820  different ways a group of four people can be selected from this group of 16.

In 35 ways four women can be chosen from the group of 7 women.

The probability that all women will be chosen to attend the conference is 1.92%.

The proportion of favourable outcomes to all possible outcomes of an event is known as the probability. The number of positive outcomes for an experiment with 'n' possible outcomes can be represented by the symbol x. The probability of an event can be determined using the following formula.

To find how many different ways can a group of four people be selected from this group of 16, we will implement the combination formula.

[tex]^n C_r=\frac{n !}{r ! (n-r) !}[/tex]

Where,

nCr = number of combinations

n = total number of objects in the set

r = number of choosing objects from the set

Here, n = 16 and r = 4, substituting the values we get

[tex]^{16} C_4=\frac{16 !}{4 ! (16-4) !}[/tex]

[tex]^{16} C_4 =[/tex] 1820

Hence, in 1820  different ways a group of four people can be selected from this group of 16.

To find how many ways can four women be chosen from the group of 7 women we will implement the combination formula.

Here, n = 7 women and r  = 4 women, substituting the values we get

[tex]^7 C_4=\frac{7 !}{4 ! (7-4) !}[/tex]

[tex]^7 C_4=[/tex] 35

Thus, in 35 ways four women can be chosen from the group of 7 women.

The probability that all women will be chosen to attend the conference is

[tex]\frac{^7 C_4}{^{16}C_4}[/tex] = 35/1820

Rule #1: If the last digit in 9.725 is less than 5, then remove the last digit.

Rule #2: If the last digit in 9.725 is 5 or more and the second to the last digit in 9.725 is less than 9, then remove the last digit and add 1 to the second to the last digit.

Rule #3: If the last digit in 9.725 is 5 or more and the second to the last digit in 9.725 is 9, and the third to the last digit is less than 9, then remove the last digit, make the second to last digit 0, and add 1 to the number to the third to the last digit.

Rule #4: If the last digit in 9.725 is 5 or more and the second to the last digit is 9, and the third to the last digit is 9, then add 1 to the number on the left side of the decimal point and make the right side of the decimal point 00.

NO. Your friend is incorrect because the solution to the system of equations on the graph is: (4, 3).

The solution to a system of linear equations is the coordinates of the point where the two lines of the linear equations intersect.

The x-coordinate and the y-coordinate of this point lie on each of the lines of the linear equations. This means that, both values of x and y are a solution to each of the linear equation given.

Therefore, the solution to a system of linear equations is usually represented as (x, y) and not just as a single value of x.

The system of linear equations that is graphed above shows that both lines intersect at (4, 3), that is, when x = 4, the value of y = 3.

However, your friend only stated the value of x = 4, as the solution to the system of linear equations that is represented on the graph.

Dividing 36 by the difference between product of 3 and 6 and the square root of 36 gives 3.

The problem asks us to divide 36 by the difference between the product of 3 and 6 and the square root of 36.

First, we need to find the product of 3 and 6, which is 18.

Then, we need to find the square root of 36, which is 6.

So, the difference between the product of 3 and 6 and the square root of 36 is 18 - 6 = 12.

Therefore, we need to divide 36 by 12.

We can do this by performing long division, or by using the calculator.

The equation of the line that has a slope of -3 and passes through the point (5, -1) is 3x + y = 14.

What is slope ?

A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate. Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively.

We know the slope point form,

y - y1 = m( x - x1 )

Where x1 and y1 atre the coordinates of the points and m is the slope.

Putting thew values from the question:

y - (-1) = -3 ( x - 5)

For the first function, the coordinates of A are (0, 1).

The equation of circle B is (x -4)^2 + y^2 = 25

And the circle intercepts the x-axis at:

(9, 0) and (-1, 0)

We have the equation:

y = a^x

And we know that A is the y-intercept of that equation, remember that the y-intercept is the point such that x = 0, so the y-coordinate will e:

y = a^0 = 1

So the y-intercept (point A)  is the point (0, 1).

We start with the circle:

x^2 + y^2 = 25

And we apply a translation of 4 units to the right, so we write this as:

(x - 4)^2 + y^2  = 25

c) The circle intercepts the x-axis when y = 0, then:

(x - 4)^2 + 0^2 = 25
