Find the value of 2^-3*3^-2

Sergeeva-Olga [200]

$2^{-3}\cdot 3^{-2}$

$2^-3=\frac{1}{2^3}$

$3^-2=\frac{1}{3^2}$

$\frac{1}{2^3}*\frac{1}{3^2}$

$\frac{1*1}{2^3*3^2}$

$2^3*3^2=72$

$=\frac{1}{72}$

Hope this helps!

Thanks!

Bill and Amy want to ride their bikes from their neighborhood to school which is 14.4 km away. It takes Amy 40 minutes to arrive

vfiekz [6]

Answer:

Amy is (21.6 - 14.4) 7.2 km/hr faster than Bill.

Distance = speed / time

Amy's speed

40 minutes = 40/60 = 2/3 hours

14.4 = speed / 2/3

Speed = 14.4 * 3/2 = 21.6 km/ hr

Bill speed

60 minutes = 1 hour

Speed = 14.4 km / hr.
