Answer:
Step-by-step explanation:
Total weight of all of the filled jars with jam = 211.2 ounces
When empty, each jar weighs 1.2 ounces
Total weight of 2 dozens of empty jar = 24 × 1.2 ounces
= 28.8 ounces
Total weight of jam in 2 dozens jar = Total weight of all of the filled jars with jam - Total weight of 2 dozens of empty jar
= 211.2 ounces - 28.8 ounces
= 182.4 ounces
The weight of jam in one jar = 182.4 ounces / 24 jars
= 7.6 ounces
The weight of jam in one jar = 7.6 ounces

Answer:
4050 sq. feet.
Step-by-step explanation:
Fencing is done on three sides of the rectangular area.
Given that there are 180 feet of fence available.
Then 2L + W = 180 ........(1), where L = length and W = width, of the rectangular plot.
Now, the area of the plot is given by A = LW
Now, from equation (1), we ger A = L (180 - 2L) ..... (2)
Then differentiating with respect to L in the both sides we get,
{Since condition for Area to be maximum is
}
⇒ L = 45 feet.
Now, from equation (2), we have
square feet.
1.5x+x=1380
2.5x=1380
x=552 miles
A is the solution.
