Tia cut a 4-meter 8-centimeter wire into 10 equal pieces. Marta cut a 540-centimeter wire into 9 equal pieces. How much longer is one of Marta’s wires than one of Tia’s? First, Tia’s wire is 4 meters and 8 centimeters long, so that means it’s 408 centimeters long, then you divide that by 10:
tia = 408/10 = 40.8 cm

Now, Marta’s wire is 540 centimeters long and we have to divide that into 9 pieces:
Marta = 540/9 = 60 cm

Finally subtract Marta’s and Tia’s pieces: 60 - 40.8 = 19.2
So Marta’s pieces are 19.2 centimeters longer than Tia’s

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

congruent segments

step-by-step explanation:

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
