Answer:
The amount of white fabric to coloured fabric as a ratio is 20:11
Step-by-step explanation:
We are given that For each 11 mm of colored fabric Nick uses to make his curtains, he also uses 2 cm of white fabric.
Length of colored fabric = 11 mm
Length of White fabric = 2 cm
1 cm = 10 mm
2 cm = 20 mm
So, length of white fabric = 20 mm
So, Ratio of the amount of white fabric to coloured fabric =
Hence the amount of white fabric to coloured fabric as a ratio is 20:11

<h2>X=6</h2>Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>- equation
- PEMDAS
<u>Ashely have </u><u>56 ways</u><u> to choose from</u>
This question can be solved using a system in mathematics called Permutation and it's in a topic of mathematics called combinatorics.
<h3 /><h3>Permutation</h3>This is the process of arranging a particular set of data in different ways.
Since Ashely is choosing 3 desserts out of 8 in no specific ways
Where n = total number of ways available
r = total numbers that would be selected.
Data given
- n = 8
- r = 3
Let's substitute these values into the equation.
From the calculation above, Ashley have 56 ways in which can choose 3 dessert from an 8 choice.
