Answer:
The scale factor of given coordinate
A is correct.
Step-by-step explanation:
We are given two coordinate O and K. The dilation with respect to origin.
For scale factor,
a is scale factor of coordinate.
If we divide new coordinate with old coordinate to get scale factor.
Hence, The scale factor of given coordinate
we know that
a1=7
r=2
n=14
then
Sn=a1*[(r^n)-1]/(r-1)-------------->S14= 7*[(2^14)-1]/(2-1)=114681
the answer is 114681
With what..............................
Percent means parts out of 100
30%=30/100=3/10
3/10 out of 720000 means 3/10 times 720,000=2160000/10=216,000
the answer is 216,000
Answer:
Step-by-step explanation:
speed = s = 3.5 miles / hour
d = 6 miles
t = ?
============
t = d / s
t = 6 / 3.5
t = 1.714 hours
t = 1 5/7 hours
You could figure this out in minutes for 5/7 but it will not make the time any clearer. You will still wind up with a fraction.
