To find the number of miles in 100 kilometers, _____.
2 answers:
Answer:
a.divide 100 by 1.609
Step-by-step explanation:
We know the relation between miles and kilometers
1 mile = 1.609 km
Now, we have to convert 100 km to miles.
Let x miles in 100 kilometers.
Hence, we have
Therefore, we can see that we have divided 100 by 1.609 in order to find the number of miles in 100 km.
Therefore, a is the correct option.

Answer:
C: (-8,3) R:5
Step-by-step explanation:
The equation of a circle can be written as:
(x-h)^2+(y-k)^2=r^2
where (h,k) is the center, and r is the radius
We have the equation:
(x+8)^2+(y-3)^2=25
Center:
The center is (-8,3)
(x+8)^2--> (x-h)^2
Therefore the x coordinate of the center is -8
(y-3)^2-->(y-k)^2
Therefore the y coordinate of the center is 3
Radius
r^2=25
Take the square root of both sides
r=5
