Answer: 11√7
<u>Step-by-step explanation:</u>
Inversely proportional means y√x=k, where k is the constant of proportionality
Find k, when x = 7 and y = 11 ----> 11√7 = k
3 1/2 miles/ (1 1/4 hour)
= (7/2 miles)/ (5/4 hour)
= 7/2* (4/5) miles/hour
= 2.8 miles/ hour
The final answer is 2.8 miles/ hour~

It is directed at 30° from the horizontal.
The force will be given by :

So, the required force is 43.30 N.
Answer:
B
Step-by-step explanation:
We know that
cos A = adjacent / hypotenuse
sin A = opposite / hypotenuse
Therefore, sin A / cos A =
(opposite / hypotenuse) / (adjacent / hypotenuse)
= (opposite/hypotenuse) * (hypotenuse / adjacent)
= opposite / adjacent
= tan A
Therefore, tan A = sin A / cos A = y/x
10 2/5 is the number......
