Two motorcyclist A and B, started simultaneously moving towards each other. From the graph given below, find the distance each o

otez555 [7]

Answer:

Distance Covered by Motorcyclist A = 400 kilometers

Distance Covered by Motorcyclist B = 300 Kilometers

Time before they met = 5 hours

Average Speed of Motorcycle A = 80 kilometers per hour

Average Speed of Motorcycle B = 60 kilometers per hour

Step-by-step explanation:

At point t = 5 and d = 300 is their <em>meeting point</em>.

Distance Covered by Motorcyclist A = from 700 to 300 (meeting point), that is 700 - 300 = 400 kilometers

Distance Covered by Motorcyclist B = from 0 to 300 (meeting point), that is 300 - 0 = 300 kilometers

The time before they met went for 5 hours as shown in graph.

Average speed of each motorcycle is given by the slope of the line. We can figure this out easily. We have to find distance traveled per hour.

Average Speed of Motorcycle A = it went 400 km in 5 hours, so 400/5 = 80 kilometers per hour

Average Speed of Motorcycle B = it went 300 km in 5 hours, so 300/5 = 60 kilometers per hour

write an expression for the cost of hiring a taxi to travel K kilometres if there is a fixed cost of $2 plus $.50per kilometres.

BigorU [14]

Well we want to pull out the important values here to determine our expression which in this case is $2 and $.50. Since the fixed cost is 2 and there is .50 per kilometer. We can say that .50(m)+2 is our expression. Hope this helps! I apologize if you were looking for something else in advance.

Probability...

jekas [21]

Answer:

$\frac{27}{1024}$

Step-by-step explanation:

So the chance of getting yellow is 0.25

Getting it once is 0.25

Getting it twice is 0.25 • 0.25

Not getting it is 0.75

So we have 0.25 • 0.25 • 0.75 • 0.75 • 0.75 = $\frac{27}{1024}$

Can anyone solve and explain please?

Leokris [45]

First take the inside diameter and divide by 2 to get the radius (4cm)
Then use $\pi$ r^2 with 'r' being your radius to get the area of the base
The area is 12.7 cm
Now multiply the height by the area of the base to get the volume/ capacity!
40cm x 12.7cm (rounded to the nearest tenth) = 502.7 cubic centimeters
