Which is greater, 4.87 x 10^9 or 9.212 x 10^8? <br> please helpp

STatiana [176]

Answer: 4.87 x 10^9 is greater than 9.212 *10^8

Step-by-step explanation:

4.87 x 10^9 is greater than 9.212 *10^8 because it has the greater exponent.

4.87 * 10^9 = 4,870,000,000

9.212 *10^8= 921,200,000

4,870,000,000 > 921,200,000

in Joell's math class there are 8 girls and 17 boys. Based on this ratio how many students would be boys in the total school of

yan [13]

So the total number of students equals 8+17 = 25 students
Proportionally:
$\frac{17}{25} = \frac{x}{100}$

Thus,
$x = \frac{17*100}{25} = 68$ boys out of the 100 students.

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
