The diameter of the sun is about 1,391,000 kilometers, and the diameter of Venus is about 12,100 kilometers. About how many times larger is the diameter of the sun than the diameter of Venus? A. 1.15 x 10^2

B. 1.4 x 10^6

C. 1.4 x 10^7

D. 1.15 x 10^3

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.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
