The rate charged per hour by the first mechanic and the second mechanic.

The total number of hours worked by the two mechanics is 10 hours + 15 hours = <<10+15=25>>25 hours. The total amount charged by the two mechanics is $2400. If we let x be the rate charged per hour by the first mechanic, and y be the rate charged per hour by the second mechanic, we can write the following equations:

x + y = 195 (the sum of the two rates is $195 per hour)
10x + 15y = 2400 (the total amount charged is $2400)

We can use the first equation to solve for one of the variables in terms of the other. For example, we can solve for y in terms of x:

y = 195 - x

We can then substitute this expression for y into the second equation:

10x + 15(195 - x) = 2400

Simplifying this equation gives us:

10x + 2925 - 15x = 2400

-5x = -525

x = 105

We can then substitute this value of x back into the first equation to find the value of y:

105 + y = 195

y = 90

Therefore, the rate charged per hour by the first mechanic is $105 per hour, and the rate charged per hour by the second mechanic is $90 per hour.

As per the difference concept, the bearing of Q from P is 132°.

To find the bearing of Q from P, we need to calculate the difference between the bearing of P from Q and 180 degrees. This is because the bearing from P to Q is the opposite direction of the bearing from Q to P.

Let's use some notation to make this clearer. Let the bearing from P to Q be denoted by B(PQ), and the bearing from Q to P be denoted by B(QP). We are given that B(PQ) = 312°. To find B(QP), we use the following formula:

B(QP) = B(PQ) - 180°

The missing vertex is located at (-14,20).

To find the missing vertex, let's assume that the third vertex is located at (x,20) and the coordinates of the other two vertices are (6,0) and (5,10). Then the coordinates of the two sides of the triangle are:

Side AB: (6,0) to (5,10)

Side AC: (6,0) to (x,20)

Using the formula for the area of a triangle, which is:

Area = 1/2 * base * height

Where the base is one of the sides of the triangle and the height is the perpendicular distance from the third vertex to the base, we can set up an equation to solve for x:

60 = 1/2 * |(6-5)*20 - (x-6)*10|

60 = 1/2 * |200 - 10x + 60|

120 = |260 - 10x|

120 = 10x - 260 or 120 = -(10x - 260)

x = -14 or x = -2

Since x has to be a negative value, the missing vertex is located at (-14,20). Therefore, the three vertices of the triangle are:

A = (6,0)

B = (5,10)

C = (-14,20)

We can verify that the area of the triangle with these vertices is indeed 60 square units using the same formula:

Area = 1/2 * |(6-5)(20-10) - (-14-6)(20-0)|

Area = 1/2 * |10 - (-400)|

Area = 1/2 * 410

Area = 205 square units

Therefore, the missing vertex is located at (-14,20).

Answer:

Let's first define our variables:

Let x be the number of students in each van and bus.

Using substitution:

From the problem, we know that:

High School A rented 8 vans and 8 buses, with a total of 240 students. So we can write the equation:

8x + 8x = 240

High School B rented 4 vans and 1 bus, with a total of 54 students. So we can write the equation:

4x + 1x = 54

Now, we can solve for x in one of the equations and then substitute that value into the other equation to solve for the other variable. For example, let's solve for x in the second equation:

5x = 54

x = 10.8

Now, we can substitute this value of x into the first equation to solve for the number of students in each van and bus for High School A:

8x + 8x = 240

8(10.8) + 8(10.8) = 172.8

So each van and bus for High School A has 10.8 students in it.

Using elimination:

We can rewrite the equations we used above in standard form:

8x + 8y = 240

4x + y = 54

We can eliminate y by multiplying the second equation by -8 and adding it to the first equation:

8x + 8y = 240

-32x - 8y = -432

-24x = -192

x = 8

Now, we can substitute this value of x into either equation to solve for y:

4(8) + y = 54

y = 22

So each van and bus for High School A has 8 students in it and each van and bus for High School B has 22 students in it.

Using graphing:

We can graph the two equations on the same coordinate plane and find the point where they intersect, which represents the solution:

8x + 8y = 240

4x + y = 54

To graph these equations, we can first solve for y in each equation:

y = -x + 30

y = -4x + 54

Then, we can plot these two lines on the same coordinate plane and find their intersection:

(6, 24)

So each van and bus for High School A has 6 students in it and each van and bus for High School B has 24 students in it.

Set B, which contains the elements 11, 15, 19, 23, 27, 31, 4n+7 and so on, is an infinite set because there exists a one-to-one correspondence between set B and a proper subset of itself, namely set F, which contains the odd integers greater than or equal to 15.

To expose that set b is infinite, we want to set up a one-to-one correspondence among set B and A proper subset of itself. Allow F to be the set of odd integers greater than or equal to 15, i. E., F = {15, 19, 23, 27, ...}.We are able to outline a characteristic f from set b to set f as follows:

f(11) = 15

f(15) = 19

f(19) = 23

f(23) = 27

f(27) = 31

f(4n+7) = 4(n+2) + 3

the first five factors of set b are mapped to the primary 5 factors of set f. For any detail 4n+7 in set b, the corresponding detail in set f is 4(n+2)+3, which is the next peculiar integer after 4n+7. It may be shown that this function is a one-to-one correspondence between set b and set f.

Consequently, given that set f is a proper subset of set b and there exists a one-to-one correspondence among them, set b should be infinite.

Answer:

7.5 feet

Step-by-step explanation:

Divide the length value by 12 for your answer

90/12 = 7.5

There are 12 inches in a foot, so to convert inches to feet, you can divide the number of inches by 12.

Therefore, a 90-inch cage is equivalent to:

90 inches ÷ 12 inches/foot = 7.5 feet

So the bird cage is 7.5 ft.

The area of the triangular piece of property is approximately 63,121.75 square feet.

The area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.

Starting at the first corner, the surveyor walks 480 ft in the direction N36°W. We can break this down into its northward and westward components:

Northward component = 480 cos(36°)

≈ 388.75 ft

Westward component = 480 sin(36°)

≈ 295.42 ft

This takes the surveyor to the second corner of the property.

From the second corner, the surveyor walks S21°W to get to the third corner. We can again break this down into its southward and westward components:

Southward component = 480 cos(21°)

≈ 435.89 ft

Westward component = 480 sin(21°)

≈ 168.75 ft

Finally, the surveyor walks N82°E to get back to the starting point.

We can break this down into its northward and eastward components:

Northward component = 388.75 ft

Eastward component = 435.89 sin(82°)

≈ 426.04 ft

Now we have the lengths of all three sides of the triangular property:

Side 1 = 480 ft

Side 2 = √[(295.42 - (-168.75))^2 + (388.75 - 435.89)^2]

≈ 421.66 ft

Side 3 = √[(426.04 - 295.42)^2 + (388.75 - 0)^2]

≈ 296.13 ft

calculate the area of the triangular property, we can use Heron's formula:

Area = √[s(s - a)(s - b)(s - c)]

where s is the semiperimeter (half the perimeter) of the triangle,

and a, b, and c are the lengths of its sides.

s = (480 + 421.66 + 296.13)/2 ≈ 598.40

Area = √[598.40(598.40 - 480)(598.40 - 421.66)(598.40 - 296.13)]

Area ≈ 63,121.75 sq ft

V = Pe^(rt)

We are given that P = $8290, r = 0.06 (since the annual interest rate is 6%), and t = 12 (since we want to find the value of the account after 12 years). Therefore, we can plug in these values and solve for V:

V = 8290 * e^(0.06*12)

V = 8290 * e^(0.72)

V = $17,936.34

To find all the values of b that will make the trinomial 3x^(2)-bx+12 factorable, we need to use the discriminant of the quadratic formula. The discriminant is the part of the quadratic formula under the square root: b^(2)-4ac. If the discriminant is a perfect square, then the trinomial will be factorable.

So we plug in the values of a, b, and c from the trinomial: b^(2)-4(3)(12) = b^(2)-144.

We want this to be a perfect square, so we can set it equal to a perfect square and solve for b:

b^(2)-144 = 36

b^(2) = 180

b = sqrt(180)

b = 6sqrt(5)

So one value of b that will make the trinomial factorable is 6sqrt(5).

Now we can plug this value of b back into the trinomial and factor it:

3x^(2)-6sqrt(5)x+12 = 0

(3x-6)(x-sqrt(5)) = 0

So the factors of the trinomial are (3x-6) and (x-sqrt(5)).

It is a multivariate statistical technique that examines the correlations among multiple observed variables in order to identify underlying latent variables, or "factors". These factors are latent, meaning they are not directly observable or measurable.

EFA helps researchers to understand how the relationships between variables can be organized and explained by underlying latent factors. Specification of EFA includes the following steps:

Using quadratic formula we get, Part A: The solutions for x are: x = (3 + √(57))/(3/2) and x = (3 - √(57))/(3/2). Part B: The first system solution is: ((3 + √(57))/(3/2), -(76 + 6√(57))/(9) + 5)  and second system solution is:                                                 ((3 - √(57))/(3/2), -(76 - 6√(57))/(9) + 5)

Part A: To solve for x, we need to first rearrange the equation so that all terms are on one side of the equal sign.  Adding (1/4)x^(2) to both sides of the equation:
-x^(2) + (1/4)x^(2) + 3x + 14 = 5

Next, combining like terms:
-(3/4)x^(2) + 3x + 14 = 5

Now, subtracting 5 from both sides:
-(3/4)x^(2) + 3x + 9 = 0

Finally, using quadratic formula to solve for x:
x = (-3 ± √(3^(2) - 4(-3/4)(9)))/(2(-3/4))

Simplifying:
x = (-3 ± √(57))/(2(-3/4))
x = (-3 ± √(57))/(-3/2)
x = (3 ± √(57))/(3/2)

Part B: To determine the system solutions, we need to plug in the values of x into the original equation and solve for y. For the first solution:
y = -(1/4)((3 + √(57))/(3/2))^(2) + 5
y = -(1/4)((9 + 6√(57) + 57)/(9/4)) + 5
y = -(1/4)((76 + 6√(57))/(9/4)) + 5
y = -(19 + (3/2)√(57))/(9/4) + 5
y = -(76 + 6√(57))/(9) + 5

For the second solution:
y = -(1/4)((3 - √(57))/(3/2))^(2) + 5
y = -(1/4)((9 - 6√(57) + 57)/(9/4)) + 5
y = -(1/4)((76 - 6√(57))/(9/4)) + 5
y = -(19 - (3/2)√(57))/(9/4) + 5
y = -(76 - 6√(57))/(9) + 5
