Answer:
Stephanie ran the fastest at 15 feet per second
Step-by-step explanation:
Frank ran the second fastest at 13.2 feet per second because it took him 60 seconds to run 792 feet, and 792/60 = 13.2
Debbie ran the third fastest at 12.08 feet per second because it took her 23 seconds to run 278 feet, and 278/23=12.086
Noah gets last place because it took him 551 seconds to run a mile, or 5280 feet, and 5280/551=9.58 feet per second

➷ As the two lengths are a, this means it is an isosceles triangle.
The two unknown angles would be equal so we can calculate them:
(angles in a triangle equal 180 degrees)
(180 - 90) / 2 = 45
Now we can use the sine rule to calculate the length a
(6 / sin(90)) x sin(45) = a
a = 4.242640687
To one decimal place, your answer would be:
a = 4.2mm

Weekly Mean Number of 50-kg bags =10.8 bags
Step-by-step explanation:
In Week 1, Kim uses 7 50kg bags of flour
In Week 2, Kim uses 14 50kg bags of flour
In Week 3, Kim uses 8 X 50kg bags of flour
In Week 4, Kim uses 13 X 50kg bags of flour
In Week 5, Kim will make 2400 loaves.
Each of these loaves will need 250g of flour.
Total Mass of flour that will be used =2400 X 250=600,000 grams
In Week 5, Kim will use 12 bags.
Therefore:
Weekly Mean number of 50kg bags of flour used in these 5 weeks.
