4 3/10 because you can turn two over five into 4/10 so to make -1 3/10 to -2 you -7/10 then -3 to get -5 then -6/10 to get -5 4/10
Answer:
A.
B.
C.
F.
Step-by-step explanation:
It might be wrong but im about to finish
Edit: This is incorrect
The student is wrong because when you simplify 8^3 you get 512 (8*8*8) and when you simplify 8^-5 you get 1/32768 (you put a 1 over 8^-5 to make it a positive fraction, then you simplify 8^5 to 8*8*8*8*8 which would be 32768). When you multiply them, you get 512/32768. Since this is a fraction and the numerator is not more than the denominator, it is less than 1.
Answer:
6%
Step-by-step explanation:
Simple Interest formula:
S.I=P×R×T/100
where
S.I is simple interest
P is principle amount
R is Annual interest rate
T is time period
[usually represented as (number of months)/12]
so
$18=$400×R/100×9/12
simplify
$18=$3600R/1200
$18=$3R
so R=$18/$3
=6
Therefore,
The Annual Interest Rate is 6%
