I hope my answer has come to your help. God bless and have a nice day ahead!
Answer:
should be - 8
Step-by-step explanation:
-2*-2=4 4*-2=-8
Let us convert all figures into decimals so that we can compare them easily.
Monday 0.3
Tuesday 15% = 0.15
Wednesday 1/6 = 0.1666
Thursday 0.2
Friday 1/8 = 0.125
Clearly, I spent the least amount of time on Friday using IT and the time is 0.125 or 1/8.
we know that
In an Arithmetic Sequence the difference between one term and the next is a constant
This problem is an Arithmetic Sequence
where
the first term is 
and
the common difference is 
In general we can write an Arithmetic Sequence as a rule
where
a1 is the first term
d is the common difference
so
<u>Find the term a7</u>
![an=a1+d*(n-1)\\ \\ a7=23+(-2)*[7-1]\\ \\\\ a7=23-12\\ \\\\ a7=11](https://tex.z-dn.net/?f=%20an%3Da1%2Bd%2A%28n-1%29%5C%5C%20%5C%5C%20%20a7%3D23%2B%28-2%29%2A%5B7-1%5D%5C%5C%20%5C%5C%5C%5C%20a7%3D23-12%5C%5C%20%5C%5C%5C%5C%20%20%20%20a7%3D11%20%20%20%20%20)
therefore
<u>the answer is</u>
Answer:
It's D.
Step-by-step explanation:
The shorter period loan has the same total interest for the same loan amount, so it has the higher effective interest rate: 80/12 is higher than 89/14.
