Salsk061 [2.6K]

<u>Step 1: Assign variable for the unknown that you need to find. </u>

Let ' t ' be the number of hours it took for the pedestrians to meet.

<u>Step 2: List the give details</u>

Speed of first pedestrian = 4 km/hr.

Speed of second pedestrian = 6 km/hr.

Distance between two pedestrians = 27 km.

<u>Step 3: Set up an equation</u>

The relationship between speed, distance and time is given below:

Distance= \; Rate \times Time

The first one walked 4 km per hour, distance traveled by first pedestrian is given below:

Distance_{1^{st} \; pedestrian} \; = \; 4t\\\\Distance_{2^{nd} \; pedestrian} \; = \; 6t

Two pedestrians simultaneously left two villages 27 km apart and walked toward each other.

Distance_{1^{st} \; pedestrian} +Distance_{2^{nd} \; pedestrian} =27\\\\4t+6t=27\\Combine \; Like \; Terms\\\\10t=27\\Dividing \; 10 \; on \; both \; sides\\\\ \frac{10t}{10}  = \frac{27}{10}  \\Simplifying \; fraction \; on \; both \; sides\\\\t=2.7 \; hours

Conclusion:

The pedestrian meet after 2.7 hours.

Transforme em π rad :<br>a)30°<br>b)40°<br>c)45°<br>d) 50°
Roman55 [17]

Answers:

a) \frac{1}{6} \pi rad

b) \frac{2}{9} \pi rad

c) \frac{1}{4} \pi rad

d) \frac{5}{18} \pi rad

Step-by-step explanation:

In this case we are dealing with angles, which can be expressed in degrees (\°) or radians (rad).

Now, before making the conversions we have to know the equivalence between degrees and radians:

180 \°=1 \pi rad

Taking this information into account, let's begin with the answers:

a) 30\° \frac{1 \pi rad}{180 \°}=\frac{1}{6} \pi rad

b) 40\° \frac{1 \pi rad}{180 \°}=\frac{2}{9} \pi rad

c) 40\° \frac{1 \pi rad}{180 \°}=\frac{1}{4} \pi rad

d) 50\° \frac{1 \pi rad}{180 \°}=\frac{5}{18} \pi rad
