The second hand on a clock is 8 cm, long.
What is the distance the tip of the second-hand travels in 10 minutes?

Round your answer to the nearest CM

Total Distance = 8.37 cm

Step-by-step explanation:

D = π2r

D = π2(8)

D = 16 π

D = 50.24

T = 60 = 1hr

T = 60/10 = T x D = 1/6 x 50.24

Total D = 8.37 cm

Alternative is we can take 1/6 as a decimal = 0.1666 x 50.24 = 8.37 cm

one way is to plot 2 points and connect them which is what the answer choices seem to be doing

it seems to be using the y intercept and the slope

y=mx+b, m=slope, b=y-intercept (where the line hits the y axis)

slope=rise/run

y-intercept is where the line croses the y axis which is the y value where x=0

you seem to have given the wrong slope (you didn't put a number in front of te x, it should be 2/3 or 3/2 looking at the answer options)

y=? x-1

m=? because of your fault

b=-1

so it has a slope of ? and y intercept of -1, meaning it pases through (0,-1)

so draw point (0,-1) (so answer is one of the first 2 option)

if slope is 2/3, then go up 2 and right 3 then draw line through those 2 points

if slope is 3/2, then go up 3 and right 2 then draw line through those 2 points

m∠abd = m∠dbc

step-by-step explanation:

given : ab bisects ∠dbc

as we know that bisection means ab divides   ∠dbc   in two equal angles named as   ∠dba and   ∠abc

so, m∠abd = m∠dbc  

because ab bisects ∠dbc.

hence , the first statement m∠abd = m∠dbc is true.
