Seenal will make 2400 loaves in week 5
Each of these loaves will need 250 g of flour.
Seenal works out the weekly mean number of 50 kg bags of flour used in these 5 weeks.
She will use this figure for future orders.
(a) Work out the weekly mean number of 50 kg bags of flour used in these 5 weeks.
(5)

Weekly mean number of bags used = 9.2 bags

Step-by-step explanation:

Seenal makes 2400 loaves in week 5

Quantity of flour used for 1 loaf = 250 g = 0.25 kg

Quantity of flour used for 2400 loaves = 0.25 * 2400 = 600 kg

Number of 50 kg bags of flour bought in week 5 = 600/50 = 12 bags

Therefore, the summary of the number of bags used in each week is:

Week 1 = 7 bags

Week 2 = 14 bags

Week 3 = 0 bags

Week 4 = 13 bags

Week 5 = 12 bags

Weekly mean number of 50 kg bags of flour used in the 5 weeks = (7+14+0+13+12)/5

Weekly mean number of bags used = 46/5 = 9.2 bags

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
