Answer:
27.50
Step-by-step explanation:
109.99=100%
10.999=10%
21.998=20%
27.4975=25%
so they are taking £27.4975 off the original price meaning the new price is £82.4925 but, because it is money, you would need to round this to two decimal places leaving the new price as £82.49
 
        
             
        
        
        
Answer:
The range of the oven is 
Step-by-step explanation:
Consider the provided information.
The internal temperature falls to 20 degrees below the set temperature and turns off when the temperature reaches 5 degrees above the set temperature. 
You preheat the oven to 405 degrees before putting a cake in and baking it for an hour at 405. 
The internal temperature falls to 20 degrees, therefore the lowest set can be:
405-20=385 degree.
The temperature reaches 5 degrees above the set temperature 405, therefore the upper set is: 405+5=410 degree.
Hence, the temperature will be lying between 385 degree and 410 degree.
This can be written as: 
Hence, the range of the oven is 
 
        
             
        
        
        
Answer:
1.  P ( tails) = 1/2
2.P (number greater than 4)   = 1/3
3.  P (2 die sum to 8) = 5/36
Step-by-step explanation:
A coin only has 2 possibilities, head or tails, and they are equally likely
So the probability of getting a tails is 1/2 
P ( tails) = 1/2
A die has the numbers 1,2,3,4,5,6 .  There are 2 numbers greater than 4.  They are 5 and 6.  So there are 2 of the 6 choices that work.
P (number greater than 4)  = 2/6  = 1/3
See the dice chart
There are 36 possibilities when you roll the die. 
There are 5 that sum to 8
P (2 die sum to 8) = 5/36
