A team of storm enthusiasts collected data to show the relationship between the time between seeing lightning and then hearing t
never [62]

Answer:

Proportionality constant = \frac{1}{5}

Step-by-step explanation:

From the graph attached,

Data set representing the relation between seeing lightning and the hearing thunder is,

{(15, 3), (25, 5), (35, 7), (45, 9)}

Since, Distance from lightening (d) ∝ Time between lightening and thunder (t)

d = kt

Here k = proportionality constant

k = \frac{d}{t}

From the data set one point is (15, 3).

k = \frac{3}{15}

k = \frac{1}{5} miles per second

Therefore, proportionality constant is \frac{1}{5} miles per second.

Please help me..........<br><br>only 32,and 33​
kupik [55]

Answer:

Step-by-step explanation:

32

Step 1 : Draw PQ = 6cm

Step 2 : Construct 60 degree at Q. [Given PQR = 60=> Q = 60 ]

Step 3 : Take 5 cm on compass and mark 5cm on the 60 degree

            line constructed at Q.

Step 4 : The arc of 5cm and 60 degree line  meets is the point R.

             [Given QR = 5cm ]

Step 5 : Given PQ || SR so construct a 120° at R ,

             because ∠PQR and ∠QRS are supplementary angle.

            [ ∠PQR + ∠QRS = 60 + 120 = 180° ]

Step 6 : At P , take 6.5 cm on compass and mark on the line drawn in

             Step 5, to get S. [ Given PS = 6.5 ]

           

33

Given adjacent sides : 4.8 and 4.2

And it is a rectangle.

Step 1 : construct AB = 4.8 cm

Step 2 :At A and B construct 90 degree

Step 3: On the compass take 4.2cm and mark on the 90degree lines

          from A and B.

Step 4 : Mark that as C and D respectively.

Step 5 : Join CD
