Answer:
180°
Step-by-step explanation:
because because that's how much the angle of this triangle is
1 5/9 × 2 6/7=??
To find this out, we have to make both fractions improper fractions, by multiplying the whole numbers with the bottom numbers(denominator) and then adding the numerator(top number).
1 5/9= (9×1) + 5 = 14/9
2 6/7= (7×2) + 6 = 20/7
Now, we multiply them together.
14/9 × 20/7
Cross multiply.
Your answer is now 40/9
Make that into a mixed number.
D) 4 4/9

Answer: 3.886 m/s
Step-by-step explanation:
1 A.
The initial velocity (u) = 10 km/hr or 2.77 m/s
1 B.
The final velocity (v) = 60 km/hr or 16.66 m/s
1 C.
5 seconds.
1D. Acceleration = Final velocity - initial velocity / time
= 16.66 m/s - 2.77 m/s / 5 s
= 3.886 m/s.
Answer:
1715 metros
Step-by-step explanation:
Lo que debemos hacer es calcular la distancia del primer y del segundo eco.
Debemos conocer la velocidad del sonido que en términos generales es 343 m/s, por lo tanto, la distancia sería igual a:
v = d/t => d = v*t
d1 = 343*2 = 686 metros
d2 = 343*3 = 1029 metros
La separación sería la suma de ambas distancias así:
686 + 1029 = 1715
1715 metros sería la distancia de separación entre ambas montañas.
