Answer:
Using the 30-60-90 triangle to find sine and cosine
sin(60 degrees) = 2√3 4.
sin(60 degrees) = √3 2.
sin(30 degrees) = 2 4.
sin(30 degrees) = 1 2.
cos(60 degrees) = 2 4.
cos(60 degrees) = 1 2.
cos(30 degrees) = 2√3 4.
cos(30 degrees) = √3 2.
 
        
             
        
        
        
Given :
Mo spends £15 on ingredients to make 40 cookies.
He sells all 40 cookies for 50p each.
To Find :
The Mo's percentage profit.
Solution :
We know, 1 £ = 66.09 p.
So, total income is :
T = 40 × 50 p
T = 2000 p 
T = £2000/66.09  
T = £30.26
So, total profit is, P = £( 30.26 - 15 ) = £15.26 .
Hence, this is the required solution.
 
        
             
        
        
        
Using the number line, the numbers that are 9 units from -5 are: -14 and 4.
<h3>How to Locate a Number on a Number line?</h3>
To find two numbers that cover the same units from a given point on a number line, we can simply do the following:
- Count the number of units given backwards/to the left from the point stated to get the first number.
- Count the number of units given forwards/to the right from the point stated to get the second number.
Thus, we are asked to find the numbers that would be 9 units from -5, using the number line.
Count 9 units backwards/to the left from -5 to get the first number, which is: -14
Count 9 units forwards/to the right from the -5 to get the second number, which is: 4.
Therefore, the numbers that are 9 units from -5 on the number line, are: -14 and 4.
