A train leaves at 11:32 and arrives at 13:24. It travelled at an average speed of 85 km/h.

Blababa [14]

Answer:

Step-by-step explanation:

<h3>Time used for journey = </h3>

13 : 24 - 11 : 32 = 1 : 92

1 : 92 = 1 hour 92 minutes

1 hour 92 minutes = 2 hours 32 minutes

<h3>changing 32 minutes to hours</h3>

1 h = 60 min

x = 32 min

x= 32 /60

x= 8/15 hours

<h3>Adding the 2hours to 8/15 hours</h3>

8/15 h + 2 h = 38 / 15

<h3>Using formula for distance</h3>

Distance = Speed × Time

Distance = 85km / h × 38 /15 h

Distance = 33.15 km

To 1DP = 33.2

For -180°<θ<0 , which of the primary trigonometric functions may have positive values?

Jobisdone [24]

Answer:

cos theta = adj / hyp is positive (+/+)

Step-by-step explanation:

In this open interval, the hypotenuse (radius) is always positive, whereas the adjacent side is positive and the opposite side negative.

in this interval:

sin theta = opp / hyp is neg (-/+)

cos theta = adj / hyp is positive (+/+)

tan theta = opp / adj = (-/+) : negative
