Answer:

<u>18</u> passengers the roller coaster can take around the track per minute.

Step-by-step explanation:

Given:

A roller coaster can take 162 passengers around the track in nine minutes. The roller coaster operates at a constant rate.

Now, to find the number of passengers roller coaster take around the track per minute.

As given in 9 minutes the roller coaster track 162 passengers.

So, we solve by using unitary method:

In 9 minutes the roller coaster take passengers = 162.

Thus, in 1 minute it can take =162\div 9 = 18.

Therefore, 18 passengers the roller coaster can take around the track per minute.

Quadrilateral ABCD is a rectangle. If AG = -7j + 7 and DG = 5j + 43, find BD
Kaylis [27]

<em>BD</em> = 56

Step-by-step explanation:

Step 1: In rectangle, the diagonals are congruent and bisect each other.

So, <em>AC</em> = <em>BD</em>

⇒<em>AG</em> + <em>GC</em> = <em>BG</em> + <em>GD</em>

⇒<em>AG</em> + <em>AG</em> = <em>GD</em> + <em>GD</em>

⇒ 2<em>AG</em> = 2<em>GD</em>

⇒<em>AG</em> = <em>GD</em>

⇒ –7<em>j </em>+ 7 = 5<em>j</em> + 43

⇒–7<em>j</em> – 5<em>j</em> = 43 – 7

⇒–12<em>j</em> = 36

⇒<em>j</em> = –3

Step 2: <em>BD</em> = 2<em>DG</em>

<em>BD</em> = 2(5<em>j</em> + 43)

     = 2(5 (–3) + 43)

     = 2(–15 + 43)

     = 2 × 28

     = 56

Hence, <em>BD</em> = 56.
