Responder:
225 kilometros
Explicación paso a paso:
Dado que :
Velocidad de funcionamiento = 30 km / h
Duración = 45 minutos
Número de días = 10 días
Distancia total recorrida por día:
Duración en horas:
45 minutos / 60 = 0,75 hora (s)
Así, la distancia recorrida por día:
Tiempo de velocidad
30 km / h * 0,75 h = 22,5 km
Por lo tanto, la distancia total recorrida durante 10 días:
Distancia recorrida diariamente * 10
22,5 kilometros * 10 = 225 kilometros
45 is b
and there is no picture of 46
Answer:
The answer to your question is x ² + y² = 64
Step-by-step explanation:
Process
1.- Find the length of the radius
C (0, 0)
P (0, -8)
d = ![\sqrt{(x2 - x1)^{2}+ (y2 - y1)^{2} }](https://tex.z-dn.net/?f=%5Csqrt%7B%28x2%20-%20x1%29%5E%7B2%7D%2B%20%28y2%20-%20y1%29%5E%7B2%7D%20%20%7D)
d = ![\sqrt{(0- 0)^{2}+ (-8 - 0)^{2} }](https://tex.z-dn.net/?f=%5Csqrt%7B%280-%200%29%5E%7B2%7D%2B%20%28-8%20-%200%29%5E%7B2%7D%20%20%7D)
d = ![\sqrt{64}](https://tex.z-dn.net/?f=%5Csqrt%7B64%7D)
d = 8
2.- Find the equation of the circle
![(x - h)^{2} + (y - k)^{2} = r^{2} \\](https://tex.z-dn.net/?f=%28x%20-%20h%29%5E%7B2%7D%20%2B%20%28y%20-%20k%29%5E%7B2%7D%20%3D%20r%5E%7B2%7D%20%5C%5C)
h = 0 and k = 0
![(x - 0)^{2} + (y - 0)^{2} = 8^{2}](https://tex.z-dn.net/?f=%28x%20-%200%29%5E%7B2%7D%20%2B%20%28y%20-%200%29%5E%7B2%7D%20%3D%208%5E%7B2%7D)
x² + y² = 64
<span>Let n = the number of pages not read
Then the number of pages read = n/4 + 3
Since the total number of pages is 193, we have
n + n/4 + 3 = 193
5n/4 = 190
n = 152
At 8 pages per day it will take 152 pages/ 8 pages/day = 19 days
