Answer:
Option A - 7.3.
Step-by-step explanation:
Given : Number 7.323.
To find : Which number is 7.323 rounded to the nearest tenth?
Solution :
Rounded to the nearest tenth rule :
1) If the hundredths place of a decimal is greater than or equal to five, then tenth place number is added by 1.
2) If the hundredths place of a decimal is less than five, then tenth place number does not change.
In the number 7.323
The Hundredth number is 2 < 5 so tenth number does not change.
7.323 rounded to the nearest tenth is 7.3.
Therefore, Option A is correct.
Answer:
Step-by-step explanation:
4x^2-8x-5=0
The discriminant is the number under the √. In this case it's 144
The calculation uses the accumulated daily balance method (ADB).
We assume the statement is based on calendar month (rare!).
George owes $500 from beginning to end of June, so 30 days out of 30.
Interest accrued is 500*0.013*30/30=$6.50.
He also owes $2000 from June 12 to June 30, so 19 days inclusively.
Interest accrued is $2000*.013*(19/30)=16.47
Total interest at the end of the month=$6.50+$16.47=$22.97
