We don't know what the question is.

It could be "What is the selling price ?"
If that's the question, then . . .

Since the store marks up their cost by 60% before they sell
the thing, the price they sell it for is

                       (1.60 of their cost).

You know their cost.  The selling price is   (1.60  x  $80) .

elena-14-01-66 [18.8K]

Complete question :

Seven cards are drawn from an ordinary deck. In how mnat ways is it possible to draw (a) only 5s (b)only 8s, 9s, and 10s, (c) no 8s, 9s, and 10s (d) exactly 2 jacks or kings, (e) 5 spades and 2 hearts?

Answer:

0; 792 ; 100396 ; 30408224 ; 18643560 ;

Step-by-step explanation:

Number of cards in a deck = 52

Number of cards to be drawn = 7

Using combination:

nCr = n! ÷ (n-r)!r!

A.)

Number of 5's in a deck = 4

4C7 = 0

(B.)

only 8s, 9s, and 10s,

Number of 8, 9 and 10's = 4 *3 = 12

12C7 = 12! ÷ 5!7! = 792

(C)

no 8s, 9s, and 10s ;

Number of cards to select from = 52 - (3(4)) = 40C7 = 18643560

(D)

exactly 2 jacks or kings,

Number of jack or king in deck = 8 ; other 5 could be any of the rest : (52 - 8) = 44

8C2 * 44C5 = 28 * 1086008 = 30408224

(e) 5 spades and 2 hearts?

Number of spades = 13

Number of hearts = 13

13C5 * 13C2

1287 * 78 = 100396

The area of the regular pentagon is 6.9 cm2. What is the perimeter? 2 cm 5 cm 10 cm 20 cm
disa [49]

Given

Area of the regular pentagon is 6.9 cm².

Find out the perimeter of a regular pentagon

To proof

Formula

Area of regular pentagon is

= \frac{1}{4}\sqrt{5(5+2\sqrt{5})}\ a^{2}

As given in the question

area of regular pentagon = 6.9 cm²

now equating the area value with the area formula.

6.9 =\frac{1}{4}\sqrt{5(5+2\sqrt{5})} a^{2}

Now put

√5 = 2.24 ( approx)

put in the above equation

\frac{6.9\times 4}{\sqrt{5(5+2\times2.24)}}=a^{2}\\\frac{27.6}{\sqrt{47.4}}=a^{2}\\\frac{27.6}{6.88}=a^{2}

thus

a² = 4.01

a = √ 4.01

a = 2.0 cm ( approx)

As perimeter  represented the sum of all sides.

i.e regular pentagon have five sides of equal length.

Thus

perimeter of the regular pentagon = 5 × side length

                                                         = 5 ×2.00

therefore the perimeter of the regular pentagon = 10cm

option c is correct

Hence proved

The midpoint of segment QR is M(-2, 9). One end point of segment QR is Q(-8, 12). Find the coordinates of the other endpoint, R.
DanielleElmas [232]

Here,

The midpoint of segment QR is M

<u>m</u><u>(</u><u>-2</u><u>,</u><u>9</u><u>)</u> x3=-2,y3=9

<u>Q</u><u>=</u><u>(</u><u>-8</u><u>,</u><u>1</u><u>2</u><u>)</u>x1=-8,y1=12

R=x2,y2

we know that,

\tt{ m=\dfrac{Q+R}{2} } ⠀

So,

x3=\tt{\dfrac{x1+x2}{2} } ⠀

\tt{-2=\dfrac{-8+x2}{2}  } ⠀

\tt{-2×2=-8+x2  } ⠀

\tt{x2=8-4  } ⠀

\tt{x2=4  } ⠀

x2=4

now we find the y coordinate y2.

y3=\tt{\dfrac{y1+y2}{2} } ⠀

\tt{9=\dfrac{12+y2}{2}  } ⠀

\tt{9×2=12+y2  } ⠀

\tt{y2=18-12  } ⠀

\tt{y2=6  } ⠀

y2=6

<em>Now</em><em> </em><em>we</em><em> </em><em>get</em><em> </em><em>the</em><em> </em><em>two</em><em> </em><em>coordinate</em><em> </em><em>of</em><em> </em><em>R</em>

<em>so</em><em>,</em>

R=(x2,y2)=(4,6)
