Ok thank you The temperature in Antarctica at noon is 14°F. By 9:00PM, the temperature had dropped by 16.2 degrees. What was the temperature at 9:00PM?
To find the temperature at 9:00 PM, we need to subtract 16.2 degrees from the initial temperature of 14°F.
14°F - 16.2°F = -2.2°F
Therefore, the temperature at 9:00 PM in Antarctica was -2.2°F.
Evaluate 4 and 1 over 2−2− 5 and 2 over 3
-3 and 1 over 2
12 and 1 over 2
2 and 1 over 6
-4 and 1 over 6
To evaluate the expression 4 and 1/2 - 2 - 5 and 2/3:
First, convert all the mixed numbers to improper fractions:
4 and 1/2 = 9/2
5 and 2/3 = 17/3
Rewrite the expression:
9/2 - 2 - 17/3
To subtract fractions, we need to have a common denominator:
The common denominator for 2 and 3 is 6.
Rewrite the fractions with the common denominator:
(9/2)*(3/3) - (2)*(3/3) - (17/3)*(2/2)
27/6 - 6/6 - 34/6
Combine the fractions:
(27 - 6 - 34)/6
-13/6
Therefore, the evaluation of the expression is:
-13/6, which is approximately -2 1/6.
