At a party, everyone shook hands with everybody else. There were 66 handshakes. How many people were at the party?

Answers

There would be 12 people at the party!

In general, with n+1 people, the number of handshakes is the sum of the first n consecutive numbers: 1+2+3+ ... + n.

Since this sum is n(n+1)/2, we need to solve the equation n(n+1)/2 = 66.

This is the quadratic equation n2+ n -132 = 0. Solving for n, we obtain 11 as the answer and deduce that there were 12 people at the party.

Since 66 is a relatively small number, you can also solve this problem with a hand calculator. Add 1 + 2 = + 3 = +... etc. until the total is 66. The last number that you entered (11) is n.

Hope this helps!

Answer:

Uhm. You didnt get this from me, But If there was 66 handshakes, and each person shakes another persons hand, all you gotta do is divide it by 2 and you get 66.

Rewrite 4x9 as addition.

Answers

Answer:

Picture Attached: 9 + 9 + 9 + 9 = 36 or 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 = 36

To find 4x9 we can stack and align the numbers by place value columns!

- Put the 6 in Ones place

- Carry the 3 to Tens place

- Answer 36!

Long addition is a process for adding numbers together:

- Stack your numbers and align the columns by place value.

- Add all numbers column by column from right to left.

- Record the sum in the answer space for each column.

- If the sum of any one column is greater than nine, carry the additional digits to the next highest column.

The value of a baseball​ player's rookie card began to increase once the player retired. When he retired in 1998 his card was worth ​$8.59. The value has increased by ​$2.05 each year since then. Express the relationship relating the value of the card y in dollars and the number of years x the player has been in retirement with an equation. Is the relationship between x and y​ proportional? What was the value of the card in 2009 ​?

Answers

Y=2.05(X)+8.59
Yes because the value of y (value of card) changes as (x) amount of years pass by.
In 2009, the card is worth $31.14

Explanation:

The answer is 7.

Line a and b are parallel lines cut by a transverse line which make angle x and y alternate exterior angles. This means that angle x and angle y have the same measurement value.

The square root of 4 is 2; so twice 2 is 4. Then three added to 4 is 7. So x is equal to 7 and thus y is also equal to 7.

Q5. A builder rents a digger. He pays a fixed charge of $30 plus $10 per hour to rent the digger. Work out how much he pays to rent the digger for: a) 1 hour b) n hours (1.5 x 2 = 3)









Q6) The width of a rectangle is x centimetres and its length is (x+ 2) cm. Write down an expression for the perimeter of the rectangle, giving your answer in its simplest form. (2+1=3 marks)

Answers

Answer:How many hours does he rent it?

Either way, the equation would be 30 + 10x

x is the number of hours he rents the digger.

So for example, if he rented it for say 8 hours

30 + 10(8)

30 + 80

$110

Step-by-step explanation:

$30 + $10(hours he rented)
For one hour: $30 + 10•1 = $40
For n hours it’s 30 + 10n

Perimeter = length + length + width + width, so P = (x + 2) + (x + 2) + x + x
P = 4x + 4 and some teachers want you to pull out the common factor of 4. If yours does that, the final answer is
P = 4(x + 1)
