Answer:

To find the volume of this composite figure, we will need to first separate it into the two rectangular prisms that make up the larger figure (You seem to have already figured that step out =) ). Let us start with the larger prism. The formula for the volume of a rectangular prism is length * width * height.

In 1991, an American, Ann Trason, set a world record by running 1000 km in 7 hours, 50 minutes, and 9 seconds. Which is the best

Lyrx [107]

We know, speed = distance / time
Here, distance = 1000 Km
t = 7 5/6 = 47/6 hours

S = 1000 * 6 / 47
S = 6000 / 47
S = 127.65 Km/h

[ Please check your distance would be 100 Km i guess, if yes, then your answer will be B) 12 Km/hr ]

Hope this helps!

Answer:

The answer is 19.

Step-by-step explanation:

Given that these lines are parallel, these two angles together equal 180.

6x +4 + 4x -14 = 180

-4 +14 +10

6x + 4x = 190

10x = 190

x = 19

Two planes left simultaneously from the same airport and headed in the same direction towards another airport 3600 km away. The

ExtremeBDS [4]

Answer:

800 kph
600 kph

Step-by-step explanation:

Equation

Let s represent the speed of the faster plane. Then its travel time is ...

time = distance/speed = 3600/s

travel time for the slower plane is ...

time = distance/speed = 3600/(s -200)

The difference in these times is 1.5 hours, so we have ...

3600/(s -200) -3600/s = 1.5

Solution

Multiplying by (2/3)s(s -200), we get ...

2400(s) -2400(s -200) = s(s -200)

s^2 -200s -480000 = 0 . . . . . . . . . . rewrite in standard form

(s -800)(s +600) = 0 . . . . . . . . . . . . . factor

The positive value of s that makes a factor zero is s = 800.

Conclusion

The speed of the faster plane was 800 km/h; of the slower plane, 600 km/h.

_____

Check

The travel time for the faster plane was 3600/800 = 4.5 hours. For the slower plane, 3600/600 = 6 hours, a difference of 1.5 hours.
