c is correct.
(Pe)²/(De)³=(Pj)²/(Dj)³ (Pe stands for period of Earth, De for Distance of Earth from Sun,
Because Dj=5.2De
(Pe)²/(De)³=(Pj)²/(5.2De)³
Pj=√(5.2³)(Pe)²=(5.2³)(1)² ≈11.9 =(note: Pe=1 earth year)
Answer:
x = 
y = -11
Explanation:
Given that a line segment BY. O is the point lies between B & Y.
Ratio is BO:OY = 5:8
Coordinate of point B = (4,2)
Coordinate of point O = (7,-3)
We will find the coordinate of Y (x,y)
Here we use the section formula.
Internal section formula is :

(7,-3) =
(7,-3) = 
Now
7 =
5x+32 = 91
x = 
and

5y + 16 = -39
y = -11
That's the final answer.
15 50
---- = ----
x 60
(15*60)/50
900/50

It takes the ostrich 18 minutes to run 15 miles.
Answer:
area = 240 in²
Step-by-step explanation:
each triangle area = 1/2(4)(15) =30 in²
30 x 8 = 240 in²
