First we should do all of the dividing of the fractions
8/20 = .4 = 40%
9/25 = .36 = 36%
9/20 = .45 = 45%
8/25 = .32 = 32%
then turn them into percentages

Define the variables for the situation. Then enter an equation.
The pencils were divided into 8 groups of 2.
p = (select)
Enter an equation:
=
8
Answer:
p = 16/8 = 2
Step-by-step explanation:
We know that the pencils were divided into 8 groups of 2.
Then the total number of pencils is equal to 8 (the number of groups) times 2 (the number of pencils in each group)
8*2 = 16
The total number of pencils is 16.
Then the operation of dividing 16 pencils into 8 groups is written as:
16/8
And we know that this is equal to 2, then the operation is:
16/8 = 2.
Then the equation is:
p = 16/8 = 2
where p represents the number of pencils in each group.

Step-by-step explanation:
For every 11 litres of petrol a car can run for 50 km.
How much petrol do you need (to 1 DP) to ensure the car has enough petrol of a trip that is 228 km?
Answer:
50.2 liters
Step-by-step explanation:
11 liters = 50km
Z liters = 228km
To get the value of Z, cross multiply
228 x 11 = Z x 50
2508 = 50z
Divide both sides by 50
2508/50 = 50z/50
50.16 = z
50.16 has two decimal places, so convert to 1 decimal place by approximation
50.16 = 50.2
Thus, 50.2 liters will be enough for 228km

Ribbon is sold by the metre.
1 metre of ribbon costs 55p.
Kate bought 16 metres of ribbon and paid with a £10 note.
How much change did she get?
Answer:
Change received by Kate = £1 and 20p
Step-by-step explanation:
Given that:
Cost of 1 meter ribbon = 55p
Ribbon bought by Kate = 16 meters
Cost of 16 meters = 16 * 55 = 880p
Amount paid by Kate = £10 = 1000p
Change received= 220p = £1.20
Change received = £1 and 20p
Hence,
Change received by Kate = £1 and 20p

The diameter of the raw cookie is 2 1 2 inches. After baking the cookie, the diameter is 5 1 2 inches. By what factor does the cookie expand? A 236% B 220% C 45% D 42%
Answer:
120%
Step-by-step explanation:
Given that,
The diameter of the raw cookie is 2 1/2 inches i.e. 5/2 inches
After baking the cookie, the diameter is 5 1/2 inches i.e. 11/2inches
We need to find by what factor does the cookie expand.
[tex]x=\dfrac{5\dfrac{1}{2}-2\dfrac{1}{2}}{2\dfrac{1}{2}}\times 100\\\\=\dfrac{\dfrac{11}{2}-\dfrac{5}{2}}{\dfrac{5}{2}}\times 100\\\\=120\%[/tex]
So, the cookie will expand 120%.

how many real zeros will x^2+19=8x+3
Answer:
The solution to the quadratic equation is:
[tex]x=4[/tex]
Thus, there will be one real zero.
Step-by-step explanation:
Given the equation
[tex]x^2+19=8x+3[/tex]
Subtract 19 from both sides
[tex]x^2+19-19=8x+3-19[/tex]
Simplify
[tex]x^2=8x-16[/tex]
Subtract 8x from both sides
[tex]x^2-8x=8x-16-8x[/tex]
Simplify
[tex]x^2-8x=-16[/tex]
Add (-4)² to both sides
[tex]x^2-8x+\left(-4\right)^2=-16+\left(-4\right)^2[/tex]
[tex]x^2-8x+\left(-4\right)^2=0[/tex]
Apply perfect square rule: (a-b)² = a² - 2ab + b²
[tex]\left(x-4\right)^2=0[/tex] ∵ [tex]x^2-8x+\left(-4\right)^2=\left(x-4\right)^2[/tex]
so solve
[tex]x-4=0[/tex]
Add 4 to both sides
[tex]x-4+4=0+4[/tex]
Simplifying
[tex]x=4[/tex]
Therefore, the solution to the quadratic equation is:
[tex]x=4[/tex]
Thus, there will be one real zero.

Answer:
I belive it would be 2:6:3
Step-by-step explanation:
I think this is right
Answer:
4:6:3
Step-by-step explanation:
If 2 red = 3 blue & 2 blue = 1 green,
We have to find a common denominator for blue2×3 = 6, therefore multiply the ratio for red and blue by 2. 2×2 = 4 red and 2×3 = 6 blue.To find green, we want our numerator to be 6, since it represents the blue. We know green is 1/2 of blue so it's 3.4 red, 6 blue, 3 green
What's the slope intercept form, simplifying all fractions.
3x +6y = 42
Step-by-step explanation:
Solving
3x + -6y = 42
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '6y' to each side of the equation.
3x + -6y + 6y = 42 + 6y
Combine like terms: -6y + 6y = 0
3x + 0 = 42 + 6y
3x = 42 + 6y
Divide each side by '3'.
x = 14 + 2y
Simplifying
x = 14 + 2y
The slope of the equation 3x +6y = 42 is - 1 / 2.
How to find the slope of an equation?The slope of a line is the change in the dependent variable with respect to the change in the independent variable.
Therefore, the equation a line can be represented in slope intercept form as follows;
y = mx + b
where
m = slopeb = y-interceptTherefore,
3x + 6y = 42
6y = -3x + 42
divide both sides by 6
y = -3x / 6 + 42 / 6
y = - 1 / 2 x + 7
Therefore, the slope is - 1 / 2.

Akhil pours a total of 6/2 cups of milk as shown in the model which expression could be used to represent the total cups of milk
Full question:
A recipe calls for 2 cups of milk for every 6 1/4 cups of flour. If you increase the flour to 43 3/4 cups, how many cups of milk will you use?
Answer:
14 cups of milk
Step-by-step explanation:
The question can be rephrased how many 6 1/4 cups of flour can we get in 43 3/4 cups of flour so that we find how many cups of milk required
6 1/4 = 25/4.
Also, 43 3/4 = 175/4
We could now divide 175/4 by 25/4 to get how many 6 1/4 cups of flour are in 43 3/4 cups of flour = 175/4 / 25/4 = 175/4×4/25= 7
This means that we have seven 6 1/4 cups of flour, therefore we require 7×2 = 14 cups of milk (given that we require 2 cups of milk for every 6 1/4 cups of flour)
