Answer:
7.83 km/h
Step-by-step explanation:
At her constant pace, Nina's time for 6 km will be found by the proportion ...
(time for 6 km)/(6 km) = (time for 9 km)/(9 km)
time for 6 km = (6 km)/(9 km) × (75 min) = 50 min
Jo's time for the same distance will be 4 minutes less: 50 -4 = 46 min. Jo's speed is ...
speed = distance/time
= (6 km)/(46/60 h) = 360/46 h ≈ 7.83 km/h . . . . Jo's speed
_____
<em>Additional comment</em>
From the 6 km point, the remaining race is half the distance already run, so will take half the time already taken. As we know, Nina will finish in 25 more minutes; Jo will finish in 46/2 = 23 more minutes, 2 minutes ahead of Nina.
Answer:
∠4 = 75°
Step-by-step explanation:
Alternate interior angles are equal.
∠6 and ∠4 are alternate interior angles.
∠6 = ∠4 = 75°
Answer:
Hay un máximo de tres ceros en el producto de un número distinto de cero cero menor que 10 y 500
Para poder ver esto, la forma más fácil para resolver este problema es multiplicar todos los números entre 1 y 9 por 500, es decir:
01*500 = 500
2*500 = 1.000
3*500 = 1.500
4*500 = 2.000
5*500 = 2.500
6*500 = 3.000
7*500 = 3.500
8*500 = 4.000
9*500 = 4.500
Como vemos, si multiplicamos a 500 por cualquier número par, entonces obtenemos un número con tres ceros, mientras que si este es impar solamente obtenemos dos ceros
