Colin gets pic 'n mix when at the cinema and makes his bag up with 3 types of sweet. He pick:
3 times as many cola bottles as smarties. He also picks twice as many smarties as
marshmallows. What proportion of the bag of sweets are cola bottles?
Give your answer in its simplest form.
Answer: 2/3
Explanation: Assume that the number of smarties he picked is c.
Now, we are given that:
1- He picked 3 times as many cola bottles as smarties. This means that:
Number of cola bottles he picked = 3s
2- He picked twice as many smarties as marshmallows. This means that:
number of marshmallows he picked = 0.5s
Now to get the proportion o f cola bottles, we will divide the number of cola bottles by the total number of sweets as follows:
proportion of cola bottles =

Answer:
The equation of required line is: [tex]\mathbf{5x-8y+34=0}[/tex]
Step-by-step explanation:
We need to write equation in the form Ax+By+C=0 of the line parallel to [tex]5x-8y+12=0[/tex] and through the point (-2,3)
First we need to find slope and y-intercept of the required line.
Using equation of line [tex]5x-8y+12=0[/tex] to find slope.
Since the given line and required lines are parallel there slope is same.
Writing equation in slope intercept form: [tex]y=mx+b[/tex] where m is slope.
[tex]5x-8y+12=0 \\-8y=-5x-12\\\frac{-8y}{-8y}=\frac{-5x}{-8}-\frac{12}{-8}\\y=\frac{5}{8}x+\frac{3}{4}[/tex]
So, the slope m = 5/8
The slope of required line is [tex]m=\frac{5}{8}[/tex]
Now finding y-intercept using slope [tex]m=\frac{5}{8}[/tex] and point(-2,3)
[tex]y=mx+b\\3=\frac{5}{8}(-2)+b\\3=\frac{-5}{4}+b\\b=3+\frac{5}{4}\\b=\frac{3*4+5}{4}\\b=\frac{12+5}{4}\\b=\frac{17}{4}[/tex]
So, the equation of required line having slope [tex]m=\frac{5}{8}[/tex] and y-intercept [tex]b=\frac{17}{4}[/tex]
[tex]y=mx+b\\y=\frac{5}{8}x+\frac{17}{4}\\y=\frac{5x+17*2}{8}\\y= \frac{5x+34}{8} \\8y=5x+34\\5x-8y+34=0[/tex]
So, The equation of required line is: [tex]\mathbf{5x-8y+34=0}[/tex]
in point slope form: passes through (-2,-1), slope = 4?
Answer:
y+1= 4(x+2)
You could also do: y - -1= 4(x- -2)

Help me out please need help !!
Answer:
Step-by-step explanation:
1.25 m + 3.50 = 12.35
3.50 the flat fee you just add up to the total
1.25 m you can see it depends on m the miles
12.35 is the total
What is the slope of the line that passes through the points (- 2, 8) and (- 22, 8) ? Write your answer in simplest form .
Answer:
0
Step-by-step explanation:
I love questions like these.
Ok so the formula for slope is
[tex]\frac{y2 - y1}{x2 - x1} [/tex]
In an ordered pair the first number is (x) and the second is (y). (x, y).
So that means y2 is the (y) of the second given pair and y1 is the y of the first given pair.
And x2 is the (x) of the second given pair, and the x1 is the (x) of the first given pair.
So now we fill in the formula.
[tex] \frac{8 - 8}{ - 22 - ( - 2)} [/tex]
simplify
[tex] \frac{0}{ - 20} [/tex]
0 divided by anything is still 0, so our slope is 0.
Well, to find slope of 2 points you need to use the point-slope formula: y2-y1/x2-x1. I attached a picture of my work so you can see what i'm talking about, but i'm going to explain what I did.
1. I labeled the coordinate pairs with x1, y1 and x2, y2. Since we know a coordinate pair looks like this (x,y), we take the first X and Y values and label them x1 and y1. Then, we take the second set of X and Y values and label them x2 and y2.
2. I plugged the numbers in where they belong in the formula. For example, when you label x1 should be -2. So on our formula, all we do is replace x1 with -2. Do that with all your numbers until the whole formula is filled in.
3. Then, solve it. You should get 0/-24 and you should always simplify your answer. However, in this situation, you cannot simplify. So, your answer is 0/-24.
Hope this helps :)

Mark is comparing prices of different brands before he goes shopping. Who has the best deal on ice cream?
Brand
Size & Price
Turkey Hill
$4.50 for 30 ounces
Breyers
$15.36 for 128 ounces
Ben & Jerrys $2.88 for 16 ounces
Answer:
Answer:
The best deal would be Breyers 15.36 for 128 ounces
Step-by-step explanation:
128/15.36 Is 8 an ounce.
However every other ice cream devided by he same amount of ounces is more that the price of breyers. So basically for bryers you get more for less!'
128/4.50= $28
128/2.88= $44

(-0.5x - 0.4) - (0.75x - 0.6)
Answer:
-1.25x + 0.2
Step-by-step explanation:
(-0.5x - 0.4) - (0.75x - 0.6) = -0.5x - 0.4 - 0.75x + 0.6
= -0.5x - 0.75x - 0.4 + 0.6
= -1.25x + 0.2

I am a trapezium, identify my properties from the following:
a. my opposite sides are parallel // b. I am a quadrilateral // c. I have all the sides equal
a. my opposite sides are parallel
FALSE. Only the basis sides are parallel.
b. I am a quadrilateral
TRUE. A trapezium has 4 sides.
c. I have all the sides equal
FALSE. The trapezium is a special shape in that it does not, unlike the square or rectangle, have to have any equal side lengths.

So I'm evaluating a newspaper articles claims.
It says: offenses have increased threefold which is (three times).
The evidence shows that in 2000 the number was 935 and in 2018 the number 2448. Does this support or contradict the claim?
Answer: The data appears to support the claim.
Explanation:
Ignore the year numbers.
Divide the two other values to get 2448/935 = 2.618
Round this to the nearest whole number to get 3
The data approximately supports the claim. It's not perfect, but it's fairly close.
