Let the original amount be A. Double that would be 2A.
Then, 2A = Ae^(r*5), or 2 = e^(5r).
Taking the natural log of both sides: ln 2 = 5r. Then r = (ln 2)/5 = 0.14
The interest rate would have to be 13.86% per year, written here as r=0.14.
Answer:
Step-by-step explanation:
33/8 < exact form
4.125 < decimal form
4 1/8 < mixed number form
Answer:
see below
a = 0.66...
b = 0.73
c = 7/8
Step-by-step explanation:
The first two numbers, 0.73 and 0.667, are near the point that is halfway between 0.6 and 0.8. That halfway point is 0.7. The value 0.667 will be below (left) of the halfway point, so is point <em>a</em>. The value 0.73 will be above (right) of the halfway point, so is point <em>b</em>. The remaining value, 7/8, must be point <em>c</em>.
__
You may know that 7/8 = 0.875, so is nearly halfway between 0.8 and 1.
_____
The attached graph has the points color-coded.
_____
Of course you know that the overline in 
indicates that digit repeats indefinitely. The value 0.667 is the number rounded to 3 decimal places.
The numerical expression for the verbal expression is 18 ÷ (2+7).
Given,
Verbal expression = Eighteen divide by the sum of two and seven
we know that ,
We can write any verbal expression to numerical expression by using playing with numbers.
Playing with numbers:
Playing with numbers involves activities like arranging the numbers, understanding , finding out whether a given number is a factor of another number or a multiple of another number, and understanding the properties of factors and multiples
Now, According to question
Eighteen divided by the sum of two and seven
18÷(2+7)
Therefore,
The numerical expression is 18÷(2+7).
