Answer:
25.05 miles per week
Step-by-step explanation:
We know that,
1 mile = 1760 yards
⇒ 920 yards = 0.522 mile
1 week = 168 hour
We need to find ts speed in miles per week.
Speed = distance/time
So, the speed of the object is 25.05 miles per week.
Answer:
A
Step-by-step explanation:
a = 10 X 5 = 50, 25 X 2 = 50 = 100
B = 15x5 = 75, 20 x 2 = 40, = 105
C = 20 x 5 = 100, already at 100 (so immediately wrong)
D: 25 x 5 = 125, already larger than 100 (so immediately wrong)
Therefore A is the only correct option, hop i helped you!

Answer:
Step-by-step explanation:
I am not clear your question.
5^(-2) / ( 5^(-3) * 5^(4))
When base is equal at multifaction index should be add.
ie. (-3) + 4 =1
5^(-2) / ( 5^((-3) +4))
5^(-2) / ( 5^(1))
When base is equal at division index should be substract.
5^(-2) / ( 5^(1))
5^((-2 )+ (-1) )
5^(-3)
We know a^(-2)= 1/ a^2
1/ 5^(3)
