The swimming instructor has a list of 152 students who have signed up for swimming lessons. The swimming instructor can register 12 students in each class. What is the least number of classes needed for all the students to be registered in a class? 1. 12
2. 13
3. 14
4 .15

2. 13

Step-by-step explanation:

152 / 12 = 12 2/3

So you have 12 groups with the maximum of 12 students per class. Then there are still (152 - 144) = 8 students left... Obviously these 8 need to be placed in a class also.

The last class does not contain the maximum students (but just 8 I stead of 12), but it is counted as a class just the same.

The least number of classes is 13, which is answer 2.

answer: l

step-by-step explanation:

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
