To find the change in the total number of bushels the farmer has for sale after 6 days, we need to calculate the total number of bushels sold in 6 days and subtract it from the initial number of bushels.

Total number of bushels sold in 6 days = (16 1/8) * 6

To simplify the calculation, let's convert the mixed number to an improper fraction:

16 1/8 = (8 * 16 + 1) / 8 = 129/8

Now, we can calculate the total number of bushels sold:

Total number of bushels sold in 6 days = (129/8) * 6 = 774/8 = 96.75

Finally, we can find the change in the total number of bushels:

Change in the total number of bushels = 180 - 96.75 = 83.25

Therefore, the change in the total number of bushels the farmer has for sale at the farmer's market after 6 days is 83.25 bushels.
Answered by GPT 3.5
After 6 days, the farmer sells a total of 16 1/8 * 6 = 97/2 = 48.5 bushels.

To calculate the change in the total number of bushels, we subtract the number of bushels sold from the initial number of bushels:

Change in total number of bushels = 180 - 48.5 = 131.5

Therefore, the change in the total number of bushels the farmer has for sale is 131.5 bushels.

To find the temperature in degrees Fahrenheit when the Celsius temperature is -15°C, we can use the formula F = (9/5)C + 32.

Substituting -15 for C in the formula:

F = (9/5)(-15) + 32
F = -135/5 + 32
F = -27 + 32
F = 5

Therefore, the temperature measured in degrees Fahrenheit when the Celsius temperature is -15°C is 5°F.

To find the change in the parachutist's elevation each second, we divide the total change in elevation (-110 ft) by the number of seconds (10):

Change in elevation each second = -110 ft / 10 = -11 ft

To simplify the expression 3b^c^2 + 6b^2c^4 - 4b^2c^4, we can combine like terms:

3b^c^2 + (6b^2c^4 - 4b^2c^4)

Simplifying the terms inside the parentheses:

3b^c^2 + 2b^2c^4

Therefore, the simplified form of the expression is 3b^c^2 + 2b^2c^4.

To simplify the expression 6(4 + t) - 4(t + 1), we can use the distributive property:

6(4 + t) - 4(t + 1) = 6(4) + 6(t) - 4(t) - 4(1)

Simplifying further:

= 24 + 6t - 4t - 4

Combining like terms:

= 2t + 20

Therefore, the simplified form of the expression is 2t + 20.
