In a second period class, 37.5% of students like to bowl. in a fifth period class, 12 out of 29 students like to bowl. in which
Ierofanga [76]

The fifth period class has a greater fraction of students that like to bowl.

Any number in the form of p/q where p and q are integers and q is not equal to 0 is a rational number. Examples of rational numbers are 1/2, -3/4, 0.3, or 3/10.

Here we have,

In second period, 37.5% students like to bowl

∴, 37.5% = 37.5/100

= 375/1000

= 0.375 students like to bowl in second period

And in fifth period, 12 students out of 29 like to bowl

Therefore, 12/29 = 0.413 students like to bowl in fifth period

Hence, on comparison

0.375 < 0.413

= 375/1000 < 12/29

Thus, fifth period class has a greater fraction of student that like to bowl as compared to second period class.

Calculate the radian measure of a 30 degree angle. Use any method you like, including sketching in the circle diagram provided.
dalvyx [7]

Answer:

The radian measure of 30° is \frac{\pi}{6} radians.

Step-by-step explanation:

A complete revolution equals 360°, that is, 2π radians. If the given angle is 30°, then the value of the radian measure is calculated by the following simple rule of three:

x = \frac{30^{\circ}}{360^{\circ}}\times 2\pi

x = \frac{\pi}{6}\,rad

The radian measure of 30° is \frac{\pi}{6} radians.
