Monarch butterflies flap their wings about 12 times a second in

1 answer:

8 0

Remember: 60 seconds in a minute, 60 minutes in one hour.
So if butterflies flap 12 times per second, multiply that number by 60 to get how many times the butterfly flaps their wings in a minute. then, multiply that number by 60 again to get the flaps of number per minute.
12x60=720x60=43,200

Chang made $156 for 13 hours of work at the same rate, how many hours would he have to work to make $108?

sdas [7]

Answer:

9 hours

Step-by-step explanation:

"At the same rate" means time and wages are proportional.

time/wages = t/$108 = (13 h)/$156

t = 108(13 h)/156 . . . . . . . . . . . . . . . units of dollars cancel

t = 9 h

Chang would have to work 9 hours to make $108.

sila put a wrong number in her calculator when multiplying the numerators

Step-by-step explanation:

Sila jogged 12 kilometers today and wants to know how far she traveled in feet. what error did sila make while converting from kilometers to feet?

StartFraction 12 kilometers Over 1 EndFraction times StartFraction 0.62 miles Over 1 kilometer EndFraction times StartFraction 5280 feet Over 1 mile EndFraction = 392,832 feet

sila put a wrong number in her calculator when multiplying the numerators.

1 km sila's first fraction should be 0 62 mi 1 mi

sila's last fraction should be 5280 ft

sila forgot to divide by 0 62 asap

(12kilometers / 1 ) × (0.62 miles / 1 kilometer) × 5280 / 1 mile

12 kilometers = 39,370.079 feet

1 kilometer = 0.621 miles
