The minute hand of a clock is 4 inches long. how far does the tipof the minute hand move in 20 minnutes?
1 answer:
This is an arc length question, but it's a little hidden. The minute hand is the radius of the circle, so r=4. Next we need to know how much of the circle the tip of the minute hand will move through. Since there are 60 minutes in an hour, the minute hand will pass through 20/60=1/3 of the clock. Then we just use the circumference formula scaled by the amount of the clock we have:

To find the mean add up all the numbers given then divide your answer by how many numbers there are.
for ex: 1,2,3,4,5
1+2+3+4+5= 15
15 divided by 5 = 3
so the mean is 3
for ex: 1,2,3,4,5
1+2+3+4+5= 15
15 divided by 5 = 3
so the mean is 3
Answer:
we can do it by simplifying 8 to to make both powers base two, and subtracting the exponents.
Step-by-step explanation:
We have been given the expression
8 can be rewritten as
Hence, the given expression becomes
After subtracting the exponents on left hand side of the equation we get:
we can do it by simplifying 8 to to make both powers base two, and subtracting the exponents.
