4 tables. 4*4 is 16, meaning that even if 4 players want to sit together it doesn't make a difference. With 16 players and 4 at a table we are going to need 4 tables.

Answer: Hence, a) 1820, b) 495.

Step-by-step explanation:

Since we have given that

Number of potential bridge players = 20

Number of tables = 4

We need to find the number of different tables of 4 from 16 potential bridge players.

So, Number of different ways would be

^{16}C_4\\\\=1820

If 4 players insist on playing together,

remaining players = 16-4 =12

so, Number of different ways would be

^{12}C_4=495

Hence, a) 1820, b) 495.

In circle pp, ad¯¯¯¯¯ad¯ is a diameter and bc¯¯¯¯¯bc¯ is perpendicular to ad¯¯¯¯¯ad¯ at ee. if pd=7pd=7 and ae=4ae=4, find cece.
kvv77 [185]
See the attached figure.

<span>ad is a diameter of the circle with center p
</span>
∵ pd = radius = 7 ⇒⇒⇒ ∴ ad = 2 * radius  = 2 * 7 = 14
∵ ae = 4 ⇒⇒⇒ ∴ ed = ad - ae = 14 - 4 = 10
∵ ad is a diameter
Δ acd is a triangle drawn in a half circle
∴ Δ acd is a right triangle at c
∵ bc ⊥ ad at point e
By applying euclid's theorem inside Δ acd
∴ ce² = ae * ed
∴ ce² = 4 * 10 = 40
∴ ce = √40 = 2√10 ≈ 6.325

The ratio of the measure of the angles of a tirangle is 1:2:3. find the measure of each angle​
SIZIF [17.4K]

Answer:

30,60,90

Step-by-step explanation:

A triangle’s interior angles sum to 180.

1:2:3 ratio

180 divided by 6 (add up the ratio numbers)= 30. Use 30 in the ratios.

(30x1=30, 30x2=60, 30x3=90)

30,60,90

30+60+90=180 (add back up to make sure they sum to 180 to check your answer)

Jed is an electrician. Jed and his wife are accrual basis taxpayers and file a joint return. Jed wired a new house for Alison an
tankabanditka [31]

Answer:

$3000

Step-by-step explanation:

Assuming that the court didn't charge any legal fee to Jed and Jed also the lawyer for this case didn't charge him anything, Jed had personally planned to get $15,000. Subtracting the amount initially paid, $10,000, Jed still needs $5,000 from Alison. Assuming a fair judgement was made, giving Jed 2,000 and subtracting this from his expectation of $5,000 we remain with $3,000. Therefore, we can conclude that the $3,000 is the loss he should record out of this deal.
