A student is asked to find the length of the hypotenuse of a right triangle. The length of one leg is 38 ​centimeters, and the length of the other leg is 25 centimeters. The student incorrectly says that the length of the hypotenuse is 7.9 centimeters.

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)

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.

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.

When D’Ante looked at the car lot, he noticed that for every 2 red vehicles, there were 6 grey vehicles. If there are 144 total vehicles in the parking lot, how many of them are red? How many are grey?

Answers

Answers:

36 red cars108 grey cars

========================================================

Work Shown:

The ratio 2 red : 6 grey reduces to 1 red : 3 grey when we divide both parts by 2. For every 1 red car, there are 3 grey cars. There are triple as many grey compared to red.

Let x be the number of red cars. Since there are 3 times as many grey cars, this means 3x represents the number of grey cars.

The total number of cars can be represented by the expression x+3x = 4x

Set this equal to the total number of cars (144) and solve for x

4x = 144

x = 144/4

x = 36

There are 36 red cars.

Subtract that value from 144 to find 144-36 = 108 grey cars.

----------------------------------------

An alternative way to solve:

(2 red)/(6 grey) = (x red)/( (144-x) grey)

2/6 = x/(144-x)

2(144-x) = 6x .... cross multiply

2*144 - 2*x = 6x

288 - 2x = 6x

288 = 6x+2x

288 = 8x

8x = 288

x = 288/8

x = 36

If there are 144 vehicles in the parking lot, then 36 cars are red.

Also, 144 - x = 144 - 36 = 108 cars are grey.

36 red cars
108 grey cars
