Answer: 1020

Step-by-step explanation:

In a 5000 m race, the athletes run 12(1)/(2) laps; each lap is 400m . Kara runs the race at a constant pace and finishes in 17.5 min. Hannah runs the race in a blistering 15.3min,  so fast that she actually passes Kara during the race. How many laps has Hannah run when she passes Kara?

Hope This Helps!

Find the angel x in d diagram above with a well structured solution.<br><br>Thanks​
Tom [10]

Step-by-step answer:

Please refer to attached image.

1. Quad PQRS is cyclic (all vertices on the same circle), so opposite angles are supplementary, meaning

  that

  angles QPS and QRS are supplementary =>

  QPS+QRS=180   =>

  QRS = 180 - 74 = 106

2. Triangle RSQ is isosceles with RS=RQ =>

   angles RSQ and RQS are congruent.

3. Angle RSQ = (180 - 106) /2 = 74 / 2  = 37

4. QP is a diameter => angle QSP is a right-angle.

5. From (3) and (4) above,

  angle RSP = 37+90 = 127

6. Since PQRS is cyclic, angles RQP  and RSP are supplementary =>

   RQP+RSP = 180   =>

   x + 127 = 180   =>

   x = 180 - 127 = 53 degrees.

suppose that A and B are points on the number line. if AB=14 and A lies at 9, where could B be located?
balandron [24]
AB means A X B so you have to do 14 / 9 which is 1.5 or there abouts.

What figure has a perimeter of 22 units?
Sav [38]
Without knowing the shape selection you have i cant really say anything.  But with a square you wouldnt have any whole numbers, nor would a triangle give you whole number, than again no shape that i can think of would give whole numbers.
