Answer:

The distance from Earth to Mars is 8×10¹¹ m.

Step-by-step explanation:

Given that,

The speed of light is 3×10⁸ m/s. The sun is approximately 230,000,000,000 m from Mars. If the sun is approximately 1.5 x 10¹¹ meters from Earth, what is the approximate distance from Earth to Mars.

The sun is approximately 2.3 × 10¹¹ m from Mars.

The sun is approximately 1.5 x 10¹¹ m from Earth.

The distance between from Earth to Mars is :

d = 2.3 × 10¹¹ m - 1.5 x 10¹¹ m

= 8×10¹¹ m

Hence, the distance from Earth to Mars is 8×10¹¹ m.

Suppose that you work part-time as a sales representative at a car dealership. You earn a base salary of $125 per week plus a 18
elena-14-01-66 [18.8K]
Define the two friends as person A and person B.

Let x =  the sales in a week.

Person A:
$125 per week plus 18% commission on sales.
Earnings in a week on x sales is
125 + 0.18x

Person B:
$85 per week plus 21% commission on sales.
Earnings in a week on x sales is
85 + 0.21x

For the two earnings to be equal,
85 + 0.21x = 125 + 0.18x
0.03x = 40
x = 40/0.03 = $1333.33

Answer: $1,333.33
