Answer:

The angle the minute hand travels in 4 full rotations is 8\ pi\ radians

Step-by-step explanation:

We know that one complete rotation is given by :

1\ rotation=1\ hour

and 1\ hour=60\ minutes=2\ \pi    

So, 1\ rotation=2\ \pi

Using unitary method we can find the minute hand travel in 4 rotations.

\because 1\ rotation=2\ \pi\ radians

So,  4\ rotation=8\ \pi\ radians

Hence, this is the required solution.

Use the number line​ below, where RS=5y+5​, ST=2y+5, and RT=52. a. What is the value of​ y? b. Find RS and ST.
Alchen [17]

Answer:

y = 6, RS = 35 and ST = 17

Step-by-step explanation:

Given that,

RS = 5y+5

ST = 2y+5

RT = 52

If we consider a number line,

RT = RS + ST

52 = 5y+5 + 2y+5

52 = 7y + 10

7y = 52-10

7y = 42

y = 6

RS = 5y+5

= 5(6)+5

= 35

ST = 2y+5

= 2(6) +5

= 17

Hence, this is the required solution.
