kondaur [170]

Answer:

1) 7 x 10^{15} J

2) 40.5 days

Step-by-step explanation:

1) First of all we use 1MJ=1x10^{6}J so the total energy will be 7x10^{9} kg * 1x10^{6} \frac{J}{kg} =7x10^{15}J.

2)Then we use 1W=1\frac{J}{s} and Time=\frac{7 x 10^{15} J }{2x10^{9}J/s} =3.5x10^{6}s or 3.5x10^{6}s*\frac{1h}{3600s}*\frac{1day}{24h} =40.5 days

PLEASE HELP- Vanessa earns a base salary of $400.00 every week with an additional 5% commission on everything she sells. Vanessa
matrenka [14]
The commission is 5% on everything she sells
If she sold $1650.00
First you have to find her commission
100%=1650
5%=x
100•x=1650•5
100•x=8250
—— ———
100 100
x=82.5(this is her commission)
Now you have to add $82.5 to total she earns in the week.
$400.00+ $82.5 = $482.5
The Vanessa’s total pay last week was $482.5
