Answer:

40.95

Step-by-step explanation:

If the jacket is 40% off, you still have to pay 100% -40% or 60%

The new price is the original price times 60%

new price = 65*60%

                 =39

We need to find the sales tax

tax= price * tax rate

    = 39 * 5%

   = 39 *.05

   =1.95

Final cost is the new price plus the tax

Final cost = 39+1.95

                 =40.95

40% off means you are paying 60% of the original price ( 100% - 40% = 60%


Multiply the price of the coat by 60%:

65.00 x 0.60 = 39.00 ( sale price)

Now multiply the sale price by 1.05 ( price of coat plus tax rate) to get the final cost:

39.00 x 1.05 = 40.95


The final price is $40.95

What is typically used to quantitatively compare the effectiveness of layouts? A. trial and error B. load-distance model C. expo
Andre45 [30]

Answer:

B. load-distance model

Step-by-step explanation:

A. trial and error

Trial and error is "a fundamental method of problem solving. It is characterised by repeated, varied attempts which are continued until success". But this method is not the best in order to compare effectiveness of layouts

B. load-distance model

The load-distance method is a "mathematical model used to evaluate locations based on proximity factors. The objective is to select a location that minimizes the total weighted loads moving into and out of the facility. The distance between two points is expressed by assigning the points to grid coordinates on a map". And that's the correct option since we are trying to measure the effectiveness of layouts quantitatively.

C. exponential smoothing

This is "a rule of thumb technique for smoothing time series data using the exponential window function". Wheighting observations using the exponential function. But this is a techinique used to smooth s time series not to compare effectiveness of layouts.

D.process control charts

The Control Chart is a "graph used to study how a process changes over time with data plotted in time order". But we don't want to see how the process changes the objective is quantitatively compare the effectiveness of layouts, and this one is not the best option for this.

E. mean absolute deviation (MAD)

The median absolute deviation(MAD) is "a robust measure of how spread out a set of data is. The variance and standard deviation are also measures of spread, but they are more affected by extremely high or extremely low values and non normality". But again is just a measure of spread and not allow to compare effectiveness of layouts.

How to find unknown side
Elan Coil [88]

Answer:

C = 10

Step-by-step explanation:

Find the last side of the triangle using the Pythagorean theorem.

a^{2} +b^{2} =c^{2}

You have a and b already, a = 6, b = 8

6^{2} +8^{2} =c^{2} \\\\

solve this to get

64 + 36 = \sqrt{100}

C = 10

Apply the same to the other 2 triangles. C is your longest side!

HELP PLEASE! whats the height and base??
ddd [48]

Answer: 7.5

Step-by-step explanation:

Area of the bottom left triangle = 4x3/2 = 6

Bottom right = 6x3/2 = 9

Top right = 3x4/2 = 6

Top left = 6x3/2 = 9

6+9+6+9 = 30

Each square unit is 4

So the answer should be 30/4 = 7.5

Hope this is correct
