X=40 with the little house thingy
Answer:
5.2
Step-by-step explanation:
distance(Mercury, Sun) = 5.8 x 10^7
distance(Venus, Sun) = 1.1 x 10^8
distance(Venus, Mars) = 1.1 x 10^8 - 5.8 x 10^7
The subtraction is a little easier if you borrow a power of 10 from the 10^8, multiplying 1.1 by 10.
simply subtract 5.8 from 11.0.
This gives us a result of 5.2 x 10^7.

Answer:
5.89 feets
Step-by-step explanation:
Arc length :
L = θ/ 360° * 2πr
Diameter = 15 ; Radius, r = 15 / 2 = 7.5
θ = 45°
L = (45/360) * 2*3.14 * 7.5
L = 0.125 * 2 * 3.14 * 7.5
L = 5.89 feets
