Answer:
£15.20
Step-by-step explanation:
butter : sugar : flour = 2 : 1 : 9
Total mass for 1 recipe = 30 g
2 + 1 + 9 = 12
12x = 30
x = 30/12
x = 2.5
For 1 scone:
butter = 2x = 2(2.5) g = 5 g
sugar = x = 2.5 g
flour = 9x = 9(2.5) g = 22.5 g
Cost for 1 scone:
butter: 5 g × £2.50/(500 g) = £0.025
sugar: 2.5 g × £1.60/(1000 g) = £0.004
flour: 22.5 g × £0.6/(1500 g) = £0.009
Cost for 1 recipe = £0.025 + £0.004 + £0.009 = £0.038
Cost for 400 scones = 400 × £0.038 = £15.20
Answer: £15.20
Answer:
P = 867(1.07)^t
Step-by-step explanation:
The population of muskrats oscillates 33 above and below average during the year, hitting the lowest value in january.
If the average value = 900 muskrats
Then the lowest = 900 - 33 = 867
It increases by 7 % each month
R = 7%
equation for the population p in terms of the months since january t will be
P = Po( 1 + R%)^t
P = 867( 1 + 0.07) ^t
P = 867(1.07)^t
Answer:
The sum of the areas of the two shaded sectors is 
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
The area of a circle is equal to
where
r is the radius of the circle
in this problem we have
substitute
Remember that
subtends the complete circle of area equal to 
so
By proportion
Find the area of the two shaded sectors
Answer:
8/12
Step-by-step explanation:
Given that:
Dividing into 12 steps
Total step, fraction = 1
Each of the 12 steps = 1/12
If two steps is completed in one day:
. Steps completed per day :
2 (1/12)
= 2 /12 steps per day
Fraction of steps completed after 4 days
Fraction of steps per day * number of days
2 /12 * 4
(4*2) / 12
8/12
