Answer:
Haeather ran at a speed of 5 miles per hour.
Step-by-step explanation:
Given that last week at the park Haeather ran 4 miles in 48 minutes, to determine what was Haeather rate of speed in miles per hour the following mathematical calculation must be performed:
48/4 = 12
Thus, Haeather ran 1 mile every 12 minutes.
60/12 = 5
1 x 5 = 5
Therefore, Haeather ran at a speed of 5 miles per hour.
Answer:

Yes, you are right, you need to flip the second fraction:
Answer:
No
Step-by-step explanation:
According to the Inequality Theorem, the sum of 2 side of a triangle must always be longer than the third one. 4 + 6 = 10 which is not larger than 11.
In a proof, the figure should fit the hypothesis sometimes.
A hypothesis is a proposed explanation based on evidence. Hypotheses aren't always correct, rather they are merely an speculation with probable reason. This means that they are not always right, but they are also not always wrong; therefore, the suitable answer is sometimes.
