Answer:

51ft^2

Step-by-step explanation:

Given data

Side of square patio= 9ft

Area= 9*9= 81 ft^2

New length = 9+3= 12ft

New Widht = 9+2= 11ft

New Area= 12*11

New Area= 132ft^2

Hence the area added is

=132-81

=51ft^2

How many possible outcomes are there on ryan's first turn flipping two cards?
GalinKa [24]

The possible outcomes are there on Ryan's first turn flipping two cards is

<h3>What are cards?</h3>

The cards are 52 in number in which 13 cards are different. Each card is four in quantity.

Ryan is playing a multiplication game with a pile of 26 cards, each with a number on them.

Each turn, he flips over two of the cards and has to  multiply the numbers.

The  number of ways in which two cards can be selected  from 26 cards, at the same time. The order of those are important.

Then, the number of possible outcomes on each flip of two cards

= 26 p(2)

= 26 x 25

=650

Thus, the possible outcomes are there on Ryan's first turn flipping two cards.

Rectangle $ABCD$ is the base of pyramid $PABCD$. If $AB = 8$, $BC = 4$, $\overline{PA}\perp \overline{AD}$, $\overline{PA}\perp
11Alexandr11 [23.1K]

Answer:

<h2>181.33</h2>

Step-by-step explanation:

Since the base of the pyramid PABCD is a rectangle, the shape in question is a rectangular based pyramid. Volume of a rectangular based pyramid is expressed as V = 1/3 * Base Area * Height of the pyramid.

Given a rectangle ABCD with AB = 8 and BC = 4, the area of the rectangle will be equivalent to the base area of the pyramid.

Base Area = Length * Breadth

Base Area = AB * BC

Base Area = 8*4 = 32

If \overline{PA}\perp \overline{AD}\ and \ \overline{PA}\perp \overline{AB}, and PB = 17, then the height of the pyramid is PB = 17.

Volume of the pyramid = 1/3 * 32 * 17

Volume of the pyramid = 1/3 * 544

Volume of the rectangular based pyramid = 181.33

Factor completely 50a2b5 − 35a4b3 + 5a3b4
Andreyy89

The complete factorisation of 50a²b⁵ − 35a⁴b³ + 5a³b⁴ is 5a²b³(10b² - 7a² + ab)

<h3>How to factorise?</h3>

Factorisation is the process of writing an expression as a product of two or more common factors.

The expression is written as a product of several factor.

Therefore,

50a²b⁵ − 35a⁴b³ + 5a³b⁴

Hence, the complete factorisation is as follows;

5a²b³(10b² - 7a² + ab)
