Answer: x ≈ 6.86°

Step-by-step explanation:

Firstly, set them equal to each other:

(7x + 24) = 72°

Subtract 24 from both sides:

7x = 48°

Divide both sides by 7:

x ≈ 6.857...

The unknown number will be -8 for the given expression.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that Hilda adds 5 to a number, then multiplies the sum by -2. Let the number be x. Form the mathematical expression from the given information and solve for the value of x.

-2 ( x + 5 ) = 6

-2x - 10 = 6

-2x = 6 + 10

-2x = 16

x = 16 / -2

x = -8

Therefore, the unknown number will be -8 for the given expression.

Answer:

There are twelve 12 bottles in one full box.

Step-by-step explanation:

From  the given information:

suppose there are 9 water bottles in the refrigerator,

and 3 full boxes of water are being added, we do not know the total number of bottles in a box, so let's represent it by b

i.e. 3b

However, two more boxes are being added which had 1 fewer bottle than the full box.

i.e.  2(b-1)

Now to determine the number of bottles in a full box, we have:

9 + 3b +2(b-1) = 67

9 + 3b + 2b - 2 = 67

5b + 7 = 67

5b = 67 - 7

5b = 60

b = 60/5

b = 12

Hence, there are twelve 12 bottles in one full box.

The nominal interest rate calculated is 7.5%.

Given that,Real rate = 1.3%Inflation premium = 5%Risk premium on interest = 1.2%.

To calculate nominal interest of the asset using information given we need to use Fisher's Equation and calculate nominal interest rate.

Nominal Interest rate = Real rate + Inflation premium + Risk premium on interest.

Nominal Interest rate = 1.3% + 5% + 1.2%Nominal Interest rate = 7.5%Therefore, the option (d) 7.5% is the correct answer.

Using Fisher's Equation, we calculated the nominal interest rate by adding the real rate, inflation premium, and risk premium on interest. The nominal interest rate calculated is 7.5%.

The statement proves the conjecture which is the area of the rectangle ABDE and AB×AE=24 units.

The formula for area is equal to the product of the length and breadth of the rectangle. Whereas when we speak about the perimeter of a rectangle, it is equal to the sum of all its four sides.

Given here: The triangle ABDE with AB and AE as the length and AB as the breadth.

Thus the area of the rectangle ABDE= 6×4

                                                             =24 units

Thus, The conjecture is True as the rectangle ABDE and the area of the rectangle is equal to 24 units.

Hence, The statement proves the conjecture which is the area of the rectangle ABDE and AB×AE=24 units.

reflection over the y axis

(x,y) ====> (-x,-y)

original points: ( -3,-1) , (-5,-1) , (-4,-3)

reflection over y axis :

(-3,-1) ===> (3,-1)

(-5,-1) ===> (5,-1)

(-4,-3) ===> (4,-3)

The given conditions cannot form a triangle. The sum of the angles in a triangle must be 180 degrees. In this case, the sum of the angles is 100 degrees (50 + 50). Therefore, there is no possible value for angle h.

Here is the calculation:

Angle G + Angle H + Angle I = 180

50 + Angle H + Angle I = 180

Angle H + Angle I = 180 - 50

Angle H + Angle I = 130

Since the sum of angle h and angle i is 130 degrees, there is no possible value for angle h that will result in a triangle with a total angle measure of 180 degrees.

If you have access to a linear programming solver or software like Excel Solver or MATLAB's Optimization Toolbox, you can enter the dual problem and use the solver to obtain the optimal solution.

To solve the dual of the given problem using the dual simplex algorithm, we first need to rewrite the primal problem in standard form. The primal problem is as follows:

Maximize: z = 11x + x + 6w

Subject to:

6x + 15x - 3w ≥ 60

3x + 2x + w ≤ 21

2x + 3x - w = 34

x ≥ 0, y ≥ 0, w ≥ 0

The dual problem will have the following form:

Minimize: w = 60y + 21z + 34u

Subject to:

6y + 3u + 2v ≥ 11

15y + 2u + 3v + u + v ≥ 1

-3y + v = 6

y ≥ 0, u ≥ 0, v unrestricted

Now, we can apply the dual simplex algorithm to solve the dual problem. The steps involved in the dual simplex algorithm include:

Start with an initial feasible solution.

Check for optimality.

If not optimal, select a pivot column and pivot row.

Perform row operations to make the pivot element 1 and all other elements in the pivot column 0.

Repeat steps 2-4 until the optimal solution is reached.

The detailed calculations and iterations involved in the dual simplex algorithm can be quite lengthy and involve complex matrix operations. It would be best to use a specialized software or linear programming solver to perform these calculations accurately and efficiently.

Answer:

The correct answer is D., 8 laps per 30 minutes.

Step-by-step explanation:

We can evaluate by making a ratio table:

Our laps are directly proportional to the time spent completing these laps. I will be measuring time in minutes, rather than hours.

laps: minutes

16: 60  *Simplify

8:30

This is also a logical answer statement as 1/2 of 16 is 8, and 1/2 of an hour (60 minutes) is 30 minutes. Therefore, you're completing 8 laps every 30 minutes.

y intercept: (0,-13)

x intercept: (13/5, 0)

Step-by-step explanation:

To find the y intercept, x has to equal zero. So, plug it in. The equation becomes y=-13.

Since x is zero, the point becomes (0,-13)

To find the x intercpet, y has to equal zero. So, plug it in. The equation becomes 0=5x-13.

move 13 to the other side

13=5x

divide by 5

13/5=x

Since y is zero, the point becomes (13/5,0)
