We know that

distance=59+70-----> 129 km
time=4+5----> 9 hours

[average speed]=129/9----------> 14.33 km/hour

Answer:

The answer is " $\bold{6.6 \times 10^{12}\ years}$ "

Step-by-step explanation:

Let the given value is:

$R=\frac{1}{9^{17}}\\\\\to \frac{N_{c_{14}}}{N_{c_{12}}}=\frac{1}{9^{17}}\\\\\to t=\frac{2.303 \times 9^{17}}{5717}=6.6\times 10^{12}\ years$

The equation a2 + b2 = ca represents the relationship between the three sides of a right triangle.

choli [55]

Answer:

Step-by-step explanation:

I think you mean a² + b² = c², not ca.

a = 10, c = 26

b² = c² - a² = 26² - 10² = 576

b = √576 = 24 ft
