Answer:
New balance = $316.8
Step-by-step explanation:
Given : Maya's unpaid balance is $205.16. Her APR is 14.4% and she has $82.10 in new transactions.
To find : What is her new balance?
Solution : First we find out the finance charge
Unpaid balance = $205.16
Finance rate = 14.4%
Finance charge = Unpaid balance × finance rate
Finance charge = $29.54
New purchase = $82.10
New balance = Unpaid balance + finance charge + new purchase
New balance = $205.16 + $29.54 + $82.10
New balance = $316.8
We can write 630 in expanded form as:
630 = 600 + 30 + 0
and in words:
630 = 6 hundreds, 3 tens and zero ones
the value 6 is 600
and the place value of 3 is 30 and the face value is 3 in the number 630.
Answer: B. Blind experiment
Step-by-step explanation: While conducting an experiment, experimenters may aim to eliminate factors which are very likely to cause bias and hence affect the veracity of the study. In the scenario above, the participants of the study (coworkers) were only provided with samples of the two coffee types without any of them knowing if it was the coffee they drank now or the new coffee brand. Hence, withholding such information from the participant is a technique in experimenting called blinding. Because, the information could affect the outcome and hence objective of the study as the participants were already partial towards the present coffee being consumed.
Answer:
21 years
