A ringing alarm clock is put under a glass jar. The air is slowly removed from the space around it. What will happen as the
air is removed? (1 point)
O The clock will slowly become less visible, until you can only hear it.
O The clock will slowly become quieter and will ultimately fade from view.
O The appearance of the clock and the sound of the clock will not change
O
The appearance of the clock will not change, but its sound will become fainter.
1. The appearance of the clock will not change, but its sound will become fainter.
2. They are waves that require some form of matter as a medium.
3. Through denser materials, because the molecules in a tightly packed medium collide more frequently.
4. Rods detect light; cones detect green, blue, and red light; and the brain combines the three colors.
5 Red stripes reflect red and absorb all other light, as does the blue square with blue; white stripes and stars reflect all wavelengths; and the flagpole absorbs all wavelengths.

Piper is going roller skating when the hands of the clock form a 150° angle. If the hands of the clock form a 60° angle now, in how many hours will Piper go roller skating?
The minute hand of a clock moves 360 degrees in 60 minutes, which means it moves 6 degrees in 1 minute.
Let's first find out how many degrees the hour hand moves between the two clock positions.
The hour hand moves 30 degrees for each hour. Between the two clock positions, it moves 150° - 60° = 90°.
So, the time elapsed between the two positions is 90° ÷ 30° per hour = 3 hours.
Therefore, in 3 hours Piper will go roller skating.
Nelson cut a pizza into equal parts. 4 of the pieces were eaten. 2 pieces were left over, creating an angle of 120°. What is the angle measure of 1 slice of pizza?
A.
36°
B.
42°
C.
60°
D.
70°
If 4 pieces were eaten, and 2 pieces were left over, then a total of 6 pieces were cut from the pizza.
The angle formed by these 6 pieces is 360° (a full circle).
The 120° angle formed by the two leftover pieces represents one-third of a full circle (since 120° is one-third of 360°).
So, each slice of pizza must be one-third of the total number of slices:
1 slice = (1/3) x 6 = 2
Therefore, each slice of pizza has an angle measure of:
360° / 2 = 180°
So, the answer is not one of the choices given.

You can use a protractor to find the measure of an angle. Place its center on the angle's vertex. Place one side of the "0" degree edge on one side of the angle. Read the measure where the other side of the angle crosses the protractor. If the angle is acute, use the lesser number. If the angle is obtuse, use the greater number.

C.
The measure of angle RWL is 50°. It is an acute angle.
D.
The measure of angle RWL is 90°. It is a right angle.
