The logo for a new company is a circle divided into 24 equally sized sectors. Six of the sectors are white, and the others are d

AveGali [126]

Answer:

r = 2.5

Step-by-step explanation:

the area of the whole circle = $\frac{13}{50}$ *π * 24

A = πr² = (13π*24)/50

r = √((13*24)/50) = 2.5 inches

A poker hand consisting of 7 cards is dealt from a standard deck of 52 cards. Find the probability that the hand contains exactl

77julia77 [94]

Answer:

The probability is 2,010,580/13,378,456

Step-by-step explanation:

Here is a combination problem.

We want to 7 cards from a total of 52.

The number of ways to do this is 52C7 ways.

Also, we know there are 12 face cards in a standard deck of cards.

So we are selecting 3 face cards from this total of 12.

So also the number of cards which are not face cards are 52-12 = 40 cards

Out of all these 40, we shall be selecting exactly 4. The number of ways to do this 40C4

Thus, the required probability will be;

(40C4 * 12C3)/52C7 = (91,390 * 220)/133,784,560

= 20,105,800/133,784,560 = 2,010,580/13,378,456

shaquana has a deck that measures 18 feet by 15 feet. She wants to increase each dimension by equal lengths so that its area tri

Svetach [21]

to increase each dimension by equal lengths so that its area triples is 12 feet.

The given dimensions are 18 feet by 15 feet.

We need to find how much should each dimension increase.

Shaquana wants to increase each dimension by equal lengths so that its area triples.

Let the increased length be x.

So, length =18+x feet and width=15+x feet.

As we know, the area of a deck=Length×Width

The original area of a deck=18×15=270 square feet.

Now, the new area of a deck=(18+x )×(15+x)=3×270

⇒270+15x+18x+x²=810 square feet

⇒x²+33x-540=0

Here, a=1, b=33 and c=-540 in $x=\frac{-b\±\sqrt{b^{2-4ac} } }{2a}$ .

⇒ $x=\frac{-33\±\sqrt{33^{2} -4 \times (-540)} }{2 \times 1}$

⇒ $x=\frac{-33\±\sqrt{1089 +2160} }{2 \times 1}=\frac{-33\±57}{2}$

⇒x=-45 or x=12

Length can not be a negative integer.

Therefore, to increase each dimension by equal lengths so that its area triples is 12 feet.

Factor 1 and 2. You do NOT need to show or explain steps for 1-2.

kogti [31]

Answer:

Step-by-step explanation:

x² + 9x + 18 = x² + 6x + 3x + 18

= x(x + 6) + 3(x + 6)

= (x + 3)(x + 6)

x² + 16x + 63 = x² + 9x + 7x + 63

= x(x + 9) + 7( x+ 9)

= (x + 7)(x + 9)

y² + 13y + 36 = y²+ 9y + 4y + 36

= y(y + 9) + 4(y + 9)

= (y + 4)(y + 9)

(a). Factored form of the expression (y² + 13y + 36) is (y + 4)(y + 9).

Therefore, Lyndsey's answer is wrong.

(b). Factors are (y + 4) and (y + 9).

(c). Factored form of the expression should be (y + 4)(y + 9) instead of Lindsey's answer (y + 6)(y + 6).
