Answer:
A) 89,458 and
E) 88,615
When rounded to the thousands place, the numbers above will round to 89,000
Step-by-step explanation:
A) 89,458
When rounded to the thousands place, the number above will round to 89,000 because 458 is less than 500 .
In rounding we check the number next to the number which is to be rounded.
If that number is less than 5 it is dropped off and if it is greater and equal to 5 it is added to the next number.
In this number we check the hundreds place to round to the thousands number.
B) 88,450
When rounded to the thousands place, the number above will round to 88,000 because 450 is less than 500 .
C) 90,054
When rounded to the thousands place, the number above will round to 90,000 because 0 is less than 5 at the hundreds place .
D) 89,905
When rounded to the thousands place, the number above will round to 90,000 because 905 is greater than 500 .
E) 88,615
When rounded to the thousands place, the number above will round to 89,000 because 615 is greater than 500 .

1). $2,700 is (2,700/6,000) = 45% of 6,000.
It took 6 years to earn it, so it earned (45%/6) = 7.5% each year.
That's the simple-interest rate.
_________________________________
2). The investment earns 4.5% each year, so it earned 9% in 2 years.
The $1,150.65 is the 9% of the original investment. Call it V.
1150.65 = 0.09 x V .
Divide each side by 0.09 :
V = 1150.65 / 0.09 = $12,785 .

3). There are 18 marbles in the bag all together.
a). 8 of them are green. If you close your eyes and pull out 1 marble,
the probability that it's a green one is
8/18 = 4/9 = 44.4% .
b). If it was a red marble, and you put it in your pocket, then
there are only 17 in the bag now, and 8 of them are still green.
If you pull another one, the probability that it's green is
8/17 = 47.1% .

5). There are 10 marbles in the bag all together.
(The second sentence doesn't say anything, and doesn't mean anything.)
If you pull out a silver marble and put it in your pocket, then
there are 9 marbles in the bag, and 2 of them are orange.
The probability of pulling an orange marble now is
2/9 = 22.2% .
