Runner A is initially 6.0 km west of a flagpole and is running with a constant velocity of 9.0 km/h due east. Runner B is initia

Eduardwww [97]

Answer:

From the data we know that runner A and runner B are 11 km apart from the start because (6+5) km

So the runner from the east direction has distance as unknown km, rate= 9 k/h ; time= d/r=x/9 hr

So runner towards the west will be

distance = 11-x, rate= 8 k/h, time = d/r = (11-x)/8

So equating east and west time we have

x/9= (11-x)/8

8x=99-9x

17x=99

x=5.92 km

That is the distance covered by runner towards the east and he will meet the runner toward the west at

6-5.92=0.08 km west of the flagpole.

A U.S. Department of Energy report estimates that over 100 billion kWh/year can be saved in the United States by various energy-

I am Lyosha [343]

Answer:

(a). 12 plants

(b). 3171 $

Explanation:

(a)first convert units of 100 billion kWh/year into Watts(W)

also convert the units of 1000 MW into Watts(W)

1 billion = 10^9

1 year = 365*24 = 8760 hrs

100 billion kWh/year = 1 $\frac{100*(10^9)*(10^3)}{8760}$

= $1.142*10^{10}$ W

1000 MW = $1000*10^{6} = 10^{9}W$

no. of plants = $\frac{1.14155*10^{10} }{10^9}$ = 11.4

So 12 plants required

(b)

savings = unit price*total units

= $0.1 * 1.142*10^{10}( \frac{1}{1000*3600} )$

= 3170.9 =3171 $
