Answer:
654
Step-by-step explanation:
109 x =16 x 2 + 43 + 32
109 x 6 = 654
654 / 3 = 218
Answer:
Part 1: 5pi/6. Part 2: 10pi/3
Step-by-step explanation:
There are 60 minutes in an hour, and there are 360⁰ in a circle, so for every one minute that passes that is 6⁰ being passed.
From the time 25 to 50 is 25 minutes, which is also 150⁰.
To convert from degrees to radians you have to multiply 150⁰ by pi/180⁰ this turns into 5pi/6.
To find how far the tip of the clock moved you have to use arc length, which is arc length=radius×angle in radians.
we know that radius is 4, because thats the length of the minute hand times the degrees in radians which is 5pi/6.
4×5pi/6=20pi/6
this reduces to
10pi/3 which is how far the minute hand traveled.
Answer:
The two numbers are 9 and 3.
Step-by-step explanation:
x+y=12
x-y=6
---------
2x=18
x=18/2
x=9
9-y=6
y=9-6
y=3
