Answer:
a) 580 - 16n
b) 9850 - 271.72n
Step-by-step explanation:
a) starting number of bales = 580
each day, the farmer feeds out 2 bales of hay to each yard. he has 8 yards, so he feeds out 2 bales 8 times for a total of 2 * 8 = 16 bales. Therefore, he loses 16 bales each day
After the first day, he has 580-16 = 564 bales. After the second, he has 564-16 = 548 bales, and so on. He loses 16 bales n times for n days, and as a result, his final amount of bales is
original amount - amount lost = 580 - 16n
b)
First, we can calculate how much a bale weighs.
average = sum/count = 9850 kg / 580 ≈ 17 kg
Therefore, as he loses 16 bales of hay, he loses 17 kg 16 times, or approximately 271.72 kg of hay every day. For n days, he loses 271.72n kg. This brings his final amount to be
starting - amount lost = 9850 - 271.72n
Answer:
6.30$
Step-by-step explanation:
If you add 7.80$ and 7.80$ that come to 4 hot dogs,
The rest of the money is how much one soda cost ( 2.40$ ),
Dividing that 7.80$ by 2, To only have one hot dog, would put you at
3.90$ fro one hot dog, then all you have to do is add them together, to get the total of 6.30
7.80 | 17.00 | 7.80/2 | 2.40
+ 7.80 | - 15.60 | 3.90 | + 3.90
15.60 | 2.40 | | 6.30
Reflection rule in the x-axis:
g(x) = - f(x)
f(x) = 3x+12
g(x) = - f(x) = -3x-12
The correct choice is option (C)
