An isosceles triangle has two equal sides (or three, technically) and two equal angles (or three, technically). The equal sides are called legs, and the third side is the base. ... The angle between the two legs is called the vertex angle. :))

Four couples at a dinner party play a board game after the meal. They decide to play as teams of two and to select the teams ran

Llana [10]

Answer:

0.29

Step-by-step explanation:

We are given that there are 4 couples i.e. 8 people

They decide to play as teams of two and to select the teams randomly

Now we are asked How likely is it that every person will be teamed with someone other than the person he or she came to the party with

For people 1 , there are 6 options for pairing Since he or she cannot pair with his /her own partner

So, Choices For people 1 will be 6 person

So, Probability that person 1 will be teamed with someone other than the person he or she came to the party with = $\frac{\text{No. of choices for Person 1}}{\text{Total no. of choices available}}=\frac{6}{7}$

So, Probability that every person (=8 person) will be teamed with someone other than the person he or she came to the party with = $(\frac{6}{7})^8=0.29$

Hence Probability that every person will be teamed with someone other than the person he or she came to the party with is 0.29

What is the solution to the equation 5(x-3) = 2(x+3)?

VikaD [51]

Answer:
x = 7

General Formulas and Concepts:
Order of Operations: BPEMDAS

Step-by-Step Explanation:
Step 1: Define
5(x - 3) = 2(x + 3)

Step 2: Solve for x
1. Distribute: 5x - 15 = 2x + 6
2. Subtract 2x on both sides: 3x - 15 = 6
3. Add 15 on both sides: 3x = 21
4. Divide both sides by 3: x = 7

Suppose you have a tablet with a capacity of 35 gigabytes. for a plain text book, one byte typically corresponds to one charact

steposvetlana [31]

The first thing we must keep in mind is the following unit conversion:
$1 gigabytes = 1 * 10 ^ 9 bytes
$
We have then that for 35 gigabytes:
$35 * (1 * 10 ^ 9) = 35 * 10 ^ 9 bytes
$

Part A:
For this case we make the following rule of three:
2000 bytes --------------> 1 page
35*10^9 bytes ----------> x
From here, we clear x:
$x = (35 * 10 ^ 9) / (2000)

x = 17500000 pages$

Part B:
Then, the number of 500-page books is:
$n = (17500000) / (500)

n = 35000

1. One of your answers is correct, but the other one is not. 14/18, 21/27 is the correct one because the relationship between both is 1.5. Your other one is wrong. The other correct answer is 7/9, 28/36 because the relationship between both is 4.
