The domain is the set of first numbers of the ordered pairs: {-1, 0, 1, 2}
9.24 / (5.5 * 6) = 9.24 / 33 = 0.28 per oz
4.68 / (6.5 * 3) = 4.68 / 19.5 = 0.24 per oz
4.48 / (3.5 * 4) = 4.48 / 14 = 0.32 per oz
so the lowest cost is the 6.5 oz tuna in packs of 3 cans for 4.68
set A = {2, 4, 6, 8, 10} (only even cards)
set B = {8, 9, 10} (8 or higher)
( A ∩ B ) means the numbers which are common in both sets .
They both have 8 & 10 in common.
So the answer is: P(A ∩ B) = {8,10}
The next larger whole number is 27 .
The next smaller whole number is 26 .
26.55 is closer to 27 than it is to 26 .
So the nearest whole number is 27 .
Answer:
4.12 kg
Step-by-step explanation:
Regular cakes:
1 dozen normal sponge cakes: 264 g plain flour
Vegetarian cakes:
1 dozen cakes: 264 g plain flour
4 eggs are replaced by 4 * 30 g of flour = 120 g flour
total flour for 1 dozen vegetarian cakes = 264 g + 120 g = 384 g
Proportion for regular cakes:
12 cakes to 264 g flour = 100 cakes to x grams flour
12/264 = 100/x
12x = 26400
x = 2200
2200 g flour for 100 regular cakes
Proportion for vegetarian cakes:
12 cakes to 384 g flour = 60 cakes to y grams flour
12/384 = 60/y
12y = 384 * 60
12y = 23040
y = 1920
1920 g flour for 60 vegetarian cakes
Total flour needed:
2200 g + 1920 g = 4120 g
4120 g * 1 kg/(1000 g) = 4.12 kg
Answer: 4.12 kg
