Which expression converts 100 inches per minute to feet per minute?
startfraction 100 inches over 1 minute endfraction × startfraction 60 minutes over 1 hour endfraction
startfraction 100 inches over 1 minute endfraction × startfraction 1 hour over 60 minutes endfraction
100 inches over 1 minute times × 1 foot over 12 inches
100 inches over 1 minute times × 12 inches over 1 foot

100 inches Over 1 minute times × 1 foot Over 12 inches

Step-by-step explanation:

Remember that

so

we have

Convert to ft/min

To convert in/min to ft/min multiply the given value by the factor 1/12

therefore

100 inches Over 1 minute times × 1 foot Over 12 inches

y=x+9

?

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
