The question is about clock hands. The acute angle measure of the hands of a clock at the time 2:20 is 80 degrees.
Clock hands are essential components of analog clocks and watches, indicating the time by their positions. Typically, a clock has three hands: the hour hand, the minute hand, and the second hand. The hour hand is shorter and denotes the hours, while the longer minute hand points to the minutes. The second hand, the thinnest and longest, measures seconds. Clock hands move in a clockwise direction, and their synchronized motion helps people tell time at a glance, making them fundamental features of timekeeping devices for centuries.
To find the acute angle measure of the hands of a clock at the time 2:20, we need to determine the angle covered by the hour hand. In going from 12 to 3, the hour hand covers 1/4 of the 12 hours needed to make a complete revolution. Therefore, the angle between the hour hand at 12 and at 3 is 90 degrees. Since it is 20 minutes past 2, the minute hand will be 1/3 of the way between 2 and 3. This means the minute hand will be at an angle of 1/3 x 30 degrees = 10 degrees. The acute angle between the hour and minute hands can be found by subtracting the smaller angle from the larger angle. So, the acute angle measure of the hands of the clock at the time 2:20 is 90 degrees - 10 degrees = 80 degrees.

Answer:
50 degrees
Step-by-step explanation:
To find the acute angle measure between the hour and minute hands of a clock at 2:20, you can use the following method:
First, calculate the minute hand's position:
The minute hand moves 360 degrees in 60 minutes, so in 20 minutes, it covers (20/60) * 360 = 120 degrees.
Next, calculate the hour hand's position:
The hour hand moves 360 degrees in 12 hours, so in 2 hours and 20 minutes, it covers (2 + 20/60) * (360/12) = (2 + 1/3) * 30 = (7/3) * 30 = 70 degrees.
Now, find the acute angle between the hour and minute hands:
Subtract the hour hand position from the minute hand position:
120 degrees (minute hand) - 70 degrees (hour hand) = 50 degrees.
So, the acute angle measure between the hands of the clock at 2:20 is 50 degrees.
To convert the ratio 9 yards to 48 feet into a fraction in simplest form, we need to first convert 9 yards into feet, which is 27 feet. Then, we express this ratio as a fraction, 27/48. To simplify this fraction, we divide both numerator and denominator by their GCD, which is 3, resulting in 9/16.
The student has asked to express the ratio 9 yards to 48 feet as a fraction in simplest form. Given that 1 yard equals 3 feet, we first need to convert 9 yards to feet. So, 9 yards * 3 feet/1 yard = 27 feet.
Now, let's express 27 feet to 48 feet as a fraction. The ratio is 27:48, and we can write this as the fraction 27/48. However, this is not the simplest form. We simplify a fraction by dividing both the numerator (top number) and the denominator (bottom number) by their greatest common divisor (GCD). The GCD of 27 and 48 is 3. Therefore, we divide 27 and 48 by 3 to get 9/16. So, the fraction in simplest form is 9/16.
