Answer:
14.6°C
Step-by-step explanation:
Method 1
Higher value - lower value
12.2°C - (-2.4°C) *two negatives make a positive
12.2 + 2.4
14.6°C
Method 2
-2.4°C to 0°C = 2.4 increase (+2.4°C)
0°C to 12.2°C = 12.2 increase (+12.2°C)
Total change = 12.2 + 2.4= 14.6°C
Answer:
79
Step-by-step explanation:
To find the value of 
, when x = 3, simply plug in the value of x in the expression and solve as follows:
The value of , when x = 3, is 79
In the first digit, there are 6 possibilities. In the second, there are 5, because you can't use the digit you used before. In the third, there are 4, and in the fourth, there are 3. So,
6*5*4*3=360
There are 360 different possible four-digit numbers
The answer is 196/3 pi in^3. All you have to do is multiply 7x7, then you have to multiply that by 1/3 and 4, and you get 65.333333333. Then, you have to turn it into a fraction. You have to multiply 65 by 3, then add one, and you get 196/3 pi in^3.
