Radius, r = 939 ft

Then:

Diameter, d = 1878 ft

Circumference, C = 5899.9110034416 ft

Area, A = 2770008.2161158 ft^2

AREA = 2770 if you're shortening.

For this case we assume that the moon is spherical. For definition, the surface area of a sphere is given by:

S = 4 \pi*r ^ 2

Where:

A: It is the radius of the sphere

We have that the radius is 939 leagues.

by definition, 1 league is equivalent to 4.82803 kilometers.

ENtonces 939 leagues represent 4533.52 km.

Substituting:S = 4 \pi * (4533.52) ^ 2\\S = 20552803.5904 * 4 * \pi\\S = 258,274,147.081

It has a surface area of 258,274,147 km

ANswer:

258,274.147 km

For a special sale, a mens tie buyer plans to promote a $39.99 tie. Consequently, the buyer purchases 450 ties and wants to achi
zlopas [31]

Answer:

The average cost of each tie is $56.350

Step-by-step explanation:

We are given that a men tie buyer plans to promote a $39.99 tie. Consequently, the buyer purchases 450 ties

So, Cost of 450 ties = 450 \times 39.99=17995.5

An order for 100 ties that cost $20.00 each

Cost of 100 ties = 100 \times 20 = 2000

Total cost price = 17995.5+2000 = 19995.5

Let the selling price of 1 tie be x

Total ties = 450+100 = 550

So, SP of 550 ties =550x

Now we are given that markup is 55%

So, Profit % = 55%

So, CP = \frac{SP \times 100}{100+P\%}

Substitute the values

19995.5 = \frac{550x \times 100}{100+55}

19995.5 = \frac{550x \times 100}{155}

19995.5 \times 155 = 55000x

\frac{19995.5 \times 155}{55000}=x

56.350=x

Hence The average cost of each tie is $56.350

PLS HELP!! If f(x) = 2x^2-4x and g(x) =5-2x, evaluate f(x)-g(x) for x=5
anastassius [24]
To solve this equation you need to first start by writing out the f(x)-g(X).
The equation should be 2x^2-4x-5+2x. 
You then want to simplify the equation, I got 2x^2-2x-5.
You then want to plug in the x=5 for all the x's in the equation. 
2(5)^2-2(5)-5 would be the equation. 
The answer you get should be 35.
