Freddie is at chess practice waiting on his opponent's next move. He notices that the 4-inch-long minute hand is rotating around

the clock and marking off time like degrees on a unit circle. Part 1: How many radians does the minute hand move from 3:35 to 3:55? (Hint: Find the number of degrees per minute first.) Part 2: How far does the tip of the minute hand travel during that time? You must show all of your work

Part 1. Imagine a clock without the hour hand, When clock strikes 3:35, the minute hand is at 7. When it strikes 3:55, the minute hand is in 11. Each gap between two adjacent digits in the clock measures 30°. This is because a revolution divided by 12 is 360/12 = 30. Then, the angle between the minute hands in the picture is equal to 4(30°) = 120°. Know that π radians is equal to 180°. Converting 120° to radians,

120°(π radians/180°) = (2/3)π or 2.09 radians

Part 2. For this part, we determine the arc length intercepted by the angle 120° because this is the total distance travelled by the tip of the minute hand.

S = rθ, where θ is the angle in radians and r is the radius of the circle represented by the minute hand.
S = (4)(2.09)
S = 8.36 inches

Hence, the tip of the minute hand travelled a total distance of 8.36 inches.

John writes a number sequence starting with 8. Write the next number 8, 22, 36, _______
BlackZzzverrR [31]

Answer:

50

Step-by-step explanation:

from the question that we have been given, we have to find out the next number after 36.

John's next number sequence will be 50. Every number after 8 can be gotten by adding 14. So when we add 14 to 36, we get the final answer, which is the next number in the sequence.

This can be seen below:

14 + 8 = 22

14 +22 =36

14 +36 =50

therefore the next sequence would be 50

9. Solve the following equation.
Maru [420]
Hey there again, Bryanatwin2!

To solve for m in the equation, first we need yo distribute what's inside the parenthesis. We multiply -4 times what's in the parenthesis and we will get
-8m + 4 + 2 = 3m - 16
We combine like terms +4 +2 = 6
-8m + 6 = 3m - 16
Now we need to move all the m valued to one side
So we add 8m both sides to cancel it out on the left side and we are left with
6 = 11m - 16
Now we need to isolated 7m and to do so we add 16 to both sides to cancel it out on the right and we end up with
22 = 11m
No we have to isolate m by dividing both sides by 11 since m it's being multiplied by 11
And we get
2 = m
or m = 2
So the answer is C
