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:
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.
Points p(3,0) and q(-3,4) are on the line ax+by=6 find a and b
Answer:
to need interdependence in
the country
Step-by-step explanation:
The value of a is 3 and value of b is 3 if p(3,0) and q(-3,4) are on the line ax+by=6.
What is Straight Line?A line is an infinitely long object with no width, depth, or curvature.
If the points lie on the graph, they should satisfy it when substituted in place of x coordinate and y coordinate.
So, on substituting point P we get
3a=6
Divide both sides by 3
a=2
And on substituting point Q we get
-3a+4b=6
-3(2)+4b=6
-6+4b=6
Add 6 on both sides
4b=12
Divide both sides by 4
b=3
Hence, the value of a is 3 and value of b is 3.

12/7 is greater than 6/13 and it's asking what numbers would be incorrect meaning less than 6/13 (unmark 12/7)
1/10 is correct since 6/13 is greater than 3 / 65 (It's what you get when you multiple 1/10 with 6/13)
Unmark 4/3

Step-by-step explanation:
hello
At a party, everyone shook hands with everybody else. There were 66 handshakes. How many people were at the party?
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.

Monica is making a design for art class she is experimenting with how to transform line segment AB in her design
Answer:
it will be A. Line segment AB and its image will be the same length and in different positions.
Step-by-step explanation:
hope this helps
Answer:
A reflection does not change lengths, so answers B and D are not right.
In most cases, a reflection will change the position of any object; so answer A would be right.
However, if segment AB is contained inline l, its reflection in line l will be in the same position.
Or if line l is the perpendicular bisector of segment AB, then the reflection of segment AB inline l will be in the same position as segment AB, but with the two endpoints, A and B switched.
So, with the question as posed and no further information about the relationship of line l and segment AB, the best answer is A; but in certain cases answer, C could be right.

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)
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
