If 12a - 5 = 4a + 11 ,then a= what?

FinnZ [79.3K]

Answer:

a=2

Step-by-step explanation:

12a - 5 = 4a + 11

Subtract 4a from each side

12a-4a - 5 = 4a-4a + 11

8a -5 = 11

Add 5 to each side

8a -5+5 = 11+5

8a = 16

8a/8 = 16/8

a =2

A 150 cm pendulum swings through an arc which measured 100pi cm. In exact radians, through what angle does it swing?

choli [55]

Answer:

Pendulum will swing by an angle 0.666π

Step-by-step explanation:

We have given arc = $100\pi cm$

And length of the pendulum l = 150 cm

Length of the pendulum will be equal to radius of the pendulum so r = 150 cm

Arc is given by $arc=radius\times angle$

So $100\pi =150\times\times \Theta$

$\Theta =0.666\pi$

So pendulum will swing by an angle 0.666π
