Answer: 220
Step-by-step explanation:
When we wanto to create a group of K elements for a set of N elements (where the order of the K elements does not matter, so we do not considerate the permutations of the K elements), the number of possible combinations is:
Here N = 12 and K = 3
So there are 220 possible combinations
<span><span>If you want to convert </span>40 degrees
Celsius <span>to </span>degrees
Fahrenheit, you can do it
this way:<span>
40°C
* 9/5 + 32 = 104°F
The correct result is B. 104°F.
Other options:
A. 72°F = 22.2°C
C. 54°F = 12.2°C
D. 22°F = -5.56°C

Answer:
4 degrees every hour
Step-by-step explanation:
Since it was 48 degrees over a total of 12 hours we can do:
48 / 12 = 4 degrees.
It may be presented as -4 degrees since it is dropping in tempature therefore making it negative.
Answer: 
Step-by-step explanation:
Just translate it word-for-word.
"Eight" : 8
"more than" : +
"quotient of" : /
"a number" : x
"-5" : -5
"is less than or equal to" : 
"6" : 6
The correct answer for this question is "<span>reflect over the y-axis, reflect over the x-axis, rotate 180°." In order to get to the expected transformation, first, flip it over the y-axis which cost 90 degrees of rotation. Then lastly, flip shape from 2nd quadrant over the y-axis. It will now be coincide with the transformation at the 3rd quadrant. Could I be brainlest... I'm a middle schooler who did this so...</span>
