Mars radius = 3,393 km
Mars Mass = 6.42 x 10^23 kg
Earth Radius = <span>6,371</span><span> km
Earth Mass = </span><span>5.97237×10<span>^24kg

Gravity is directly proportional to mass and

Gravity is inversely proportional to the square of the distance. 

So, we can come up with this equation:
Force = Mass / radius^2

Force Earth = 5.97237 x 10^24 / 6,371^2
Force = </span></span><span>1.471 x 10^17

Force Mars = 6.42 x 10^23 / 3,393^2
Force = 5.577 x 10^16

Earth's gravity vs Mars' Gravity = </span>1.471 x 10^17 / <span><span>5.577 x 10^16
</span>= 2.64

Earth has 2.64 times the gravitational attraction that Mars has.
</span>So, you would weigh 834 / 2.64 =
316 Newtons on Mars.

Solve for X:<br> X + 25 = 45
tamaranim1 [39]
Hello!

All you have to is isolate the X variable :)

X  +  25  =  45
X  =   45  -  25

X  =  20

I hope this helps :))

Answer:

£3,780

Step-by-step explanation:

Total rows = 19 rows

Seats per row = 28 seats

Cost of tickets per seats = £8.75

Total number of seats at the concert = Total rows × seats per row

= 19 rows × 28 seats

= 532 seats

The tickets for 100 seats have not been sold

Total number of tickets = sold tickets + unsold tickets

532 = sold tickets + 100

532 - 100 = sold tickets

432 = sold tickets

Sold tickets = 432 tickets

Total cost estimate of sold tickets = sold tickets × cost of tickets per seats

= 432 × £8.75

= £3,780
