Answer:
4.25 m
Step-by-step explanation:
Resolvemos esta pregunta usando la fórmula:
Altura del hombre / Sombra de un hombre = Altura del palo / Sombra del palo
Sombra del hombre = 3.50 m
Altura de un hombre = 1.75 m
Sombra del palo = 8.50 m
Altura del palo = x
Por lo tanto:
1.75 / 3.5 = x / 8.5
Cruz multiplicar
1.75 × 8.5 = 3.5 × x
14.875 = 3.5x
x = 14.875 / 3.5
x = 4.25 metros
Por tanto, la altura del palo = 4.25 m
Answer:
Given that speed(v) = 20km/h and time(t) = 50 min
We have to find distance (d)
First convert speed into m/s
v = (20*1000m)/(1*3600s)
v = (50/9) m/s
Now convert time into second
t = 50*60 = 3000 sec
As we know that
d = v*t = (50/9)*3000 = 50000/3
d = 16666.67m or 16.67km
Ans: 16666.67m or 16.67km

Answer:
x = 9.6
x = - 2.6
Step-by-step explanation:
Ignore the before the ± it wouldn't let me type it correctly.
x² - 7x - 25 = 0
a = 1
b = - 7
c = - 25
Two separate equations
x = 9.6
x = - 2.6
- 9/2 x is greater than or equal to 6
-9/2 in decimal form is -4.5
-4.5 x is greater than or equal to 6
6 / -4.5 = -1.3
x = -1.3
-4.5 (-1.3) = 5.85 = 6
