Answer:
750/100 X 8 = 60
60 X 5 = 300
she will earn $300 simple interest
balance of account = $1050
compound interest
100 + 8 = 108
108/100= 1.08
750 X 1.08^5 = 1101.9960576
1102.00 - 750 = $352 compound interest
balance of account = $1102
Answer:
B, -1/3
Step-by-step explanation:
Step-by-step explanation:
162 kilometers = 162000 meters
1 hour = 3600 seconds.
162,000 meters/3600 seconds=45 meters/second=45 m/s
45*10=450
Step-by-step explanation:
x²y = k, where k is a real constant.
When x = 3.5, y = 8.
=> (3.5)²(8) = k, k = 98.
When y = 8/9,
we have x²(8/9) = (98).
=> x² = 110.25
=> x = 10.5 or x = -10.5.
Since we want the negative value,
the answer is x = -10.5.
