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.

How do I create an equation and solve for x

vekshin1

Answer:

Equation: (2x + 30) + 106 = 180

x = 22°

Step-by-step explanation:

<u>We know that the missing angle from within the triangle and the expression 2x + 30 makes 180 so we can say;</u>

180 - (33 + 41) = missing angle

180 - 74 = missing angle

<u>106</u>°<u> = missing angle</u>

Now we can set up our equation to solve for x:

(2x + 30) + missing angle = 180°

<u>(2x + 30) + 106 = 180</u>°<u> => This would be our equation:</u>

Now let's solve:

2x + 30 + 106 = 180°

2x + 136 = 180

2x = 180 - 136

2x = 44

x = 44/2

<u>x = 22°</u>

Hope this helps!
