Please use " i " to denote "interest."
the formula for simple interest is i = p r t.
Here, i = $160.67 = $2000 (r) (8/12)
Solving for the interest rate, r = ($169.67)(12/8)/ $2000 = 0.127, or 12.7%
Answer:
Out of town teenagers = 30
Step-by-step explanation:
Given that,
Total number of teenagers at a swim meet = 50
Let there are 2x locals and 3x out of town participants. The ratio of locals to out-of-town participants is 2:3.
ATQ,
2x+3x = 50
5x = 50
x = 10
Out of town teenagers = 3x
= 3(10)
= 30
Hence, there are 30 teenagers travelled from out-of-town to the swim meet.
Answer:
3 dollars and 9 cents.
Step-by-step explanation:
From the question given above, the following data were obtained:
Total amount = 20 dollars
Amount for gift A = 9 7/10 dollars
Amount for gift B = 6 2/5 dollars
Amount for gift C =?
The amount of money she has left for gift C can be obtained as follow:
A + B + C = 20
9 7/10 + 6 2/5 + C = 20
Change to improper fraction
97/10 + 32/5 + C = 20
(97 + 64)/10 + C = 20
161/10 + C = 20
Collect like terms
C = 20 – 161/10
C = (200 – 161)/10
C = 39/10
Change to mixed fraction
C = 3 9/10 dollars
C = 3.9
C = 3 dollars and 9 cents
Therefore, Kathy had 3 dollars and 9 cent for gift C
Answer: The real answer is - ask 10 students wearing football jerseys each day for a week
Step-by-step explanation: Think about it, chances are that all students they ask that are wearing a football jersey are most likely to favor football. So if you only ask people with a football jersey on, you will not get an accurate answer to represent the entire high school. You should ask people randomly instead of targeting a specific group.
