A robot moving forward at a constant speed takes 2.5 hours to travel 1 kilometer. Moving forward at this same constant speed, it
makvit [3.9K]

Answer:

The length of the hallway is 10 m.

Step-by-step explanation:

Given:

Time taken to cover 1 km = 2.5 hours

Distance covered in 2.5 hours = 1 km

Therefore, speed of robot = \frac{\textrm{Distance}}{\textrm{TIme}}=\frac{1}{2.5}=0.4\ km/h

Now, speed is constant.

Now, time taken to cover the length of hallway = 90 s

Speed of the robot = 0.4 km/h

Converting 0.4 km/h to m/s, we multiply by the factor \frac{5}{18}. This gives,

0.4\times \frac{5}{18}=\frac{1}{9}\ m/s

Now, distance of the hallway is equal to the product of speed and time. So,

Distance of hallway = Speed \times Time

Distance of hallway = \frac{1}{9}\times 90=\frac{90}{9}=10\ m

Therefore, the length of the hallway is 10 m.

what is the type of conic section is given by the equation x^2-9y^2=900 an waht is the domain and range?
Talja [164]
When the squared terms are of different signs, the equation generally describes a hyperbola. This one has its vertices at x=±30, so the parameters of interest are
  domain: (-∞, -30] ∪ [30, ∞)
  range: (-∞, ∞)

The area of a quarter circle is 38.465 square<br> inches. What is the quarter circle's radius?
LuckyWell [14K]

The formula for a circle's area is A=\pi r^2. We are given an area of 38.465 square inches for a quarter of it.

Multiply this value by 4 to compensate for the quarter circle.

4 \times 38.465=\pi r^2

153.86=\pi r^2

Divide both sides by pi (Note: I'm using the conventional value of 3.14)

49=r^2

Take the positive square root of both sides

7=r

The radius is 7 inches. Let me know if you have any questions, thanks!
