to convert 67,000 inches into miles, which two ratios could you multiply by? algebra a. 12in\1 foot and 1mile\ 5280 feet b. 1 fo

Mrrafil [7]

Use these conversions:

1 foot = 12 in

1 mile = 5280 feet

67000 in * [1 ft /12 in] * [1 mile/5280 ft]

Then the answer is the option c.

1. What is the measure in radians for the central angle of a circle whose radius is 6 cm and intercept arc length is 5.4 cm?

fgiga [73]

Hello!

1.
find circumferece
c=2pir
c=2*6*pi=12pi
intercept is 5.4

2pi radians=all

part/whole=part/whole
5.4/12pi=x/2pi
times both sides by 12pi
5.4=6x
divide both sides by 6
0.9=x
answer is 0.9 radians

2.
assuming 9pi/5 radians

find circumference
c=2pir
c=2*26.9*pi
c=53.8pi

arc/circumference=(9pi/5)/2pi

x/(53.8pi)=(9pi/5)/(2pi)
x/(53.8pi)=18/5
times both sides by 53.8pi
x=608.46266 m
about x=608.46 m

Hope this Helps! Have A Wonderful Day! :)
