Total students enrolled = 18 + 7 = 25
Mean height of these 25 students = 105 - 5 = 100 cm
Total height of all students combined = 100 x 25 = 2500cm
Final answer: 2500cm
Answer:
D
Step-by-step explanation:
When you multiply 3/4 by A, B, or C, it results in a decimal value; however, multiplying 3/4 by 8 yields 6, which is a whole number.
The Pythagorean theorem is a foundational principle. Given that 2 and 5 represent the lengths of the legs while c denotes the hypotenuse, the relevant equation would be stated as such, corresponding to the first option.
Answer E is correct, as when rounded to 3 mph and divided by 2, it yields 1.5. Since an hour consists of 60 minutes, halving that gives 30 minutes. However, because you walked a bit slower, it would actually take 5 additional minutes.
