ahrayia [7]

Answer:

yes he is correct. he spent 125% more time

Step-by-step explanation:

his original time spent  was 20 hours

he spent a new time which is 25 hours

The diameter of the sun is about 1,391,000 kilometers, and the diameter of Venus is about 12,100 kilometers. About how many time
frez [133]

Answer:

<h3>A. 1.15 x 10^2 </h3>

Step-by-step explanation:

Given the following;

Diameter of the sun ds = 1,391,000 kilometers

Diameter of the Venus dv = 12,100kilometers

Taking the ratio of both diameters;

Ratio = Diameter of sun/Diameter of Venus

Ratio = 1,391,000/12,100

Ratio = 13910/121

Ratio = 114.958

Hence ds/dv = 114.958

ds/dv = 1.149 *10^2

ds/dv = 1.15*10^2

ds = 1.15*10^2 dv

Hence the diameter of the sun is 1.15*10^2 larger than that of the venus.
