Person A's house is 8km from the library, and his friend B's house is in the opposite direction. Suppose it takes person A 3h to walk to B's house and back, and 1h to walk to the library and back, how far is B's house to the library (assuming person A always walks with constant speed)?

Answer: 16km (involves fractions because you use ratio of time and ratio of distances)

Answer:

42

Step-by-step explanation:

4x + 2 = 1/2 (4x + 44)                Be careful how you do this. I have multiplied both sides by 2

2(4x + 2) = 4x + 44                    Remove the brackets (distributive)

8x + 4 = 4x + 44                        Subtract 4x from both sides

8x-4x + 4 = 44                          

4x + 4 = 44                                Subtract 4 from both sides

4x + 4-4 = 44-4

4x = 40                                       Divide by 4

4x/4 = 40/4

x = 10

The mid line is 4x + 2

The mid line is 4*10 + 2

The mid line is 40 + 2

The mid line is 42

The base is 4x + 44

The base is 4*10 + 44

The base is 40 + 44 = 84 which is twice the midline. I did this just to show it is twice as big as the midline.

Line AB lies in the same plane as circle p, which has a radius of 6 mm. At how many points can AB intersect circle p if AP = 7 m
algol13
I think the answer is B? They didn't say whether point P is in the centre of the circle, so the answer could also actually be D. But assuming that P is the centre point of the circle, the answer should be B.

AP (7mm) > Radius of circle p (6mm)
meaning that the line should extend out of the circle from the centre of it and thus produce one intersection.

As for the rest of the line, BP,
BP (3mm) < Radius of circle p (6mm)
meaning that if the distance of point P to point B is shorter than the distance of point p from the line of the circle (this distance being the radius), it should not make another intersection.

Therefore, there is only 1 intersection and the answer should be B (if point P is the middle of circle p)
