You might need to consult your teacher or text to learn the details of the "ratio of perfect squares method" of determining an approximate square root. No reference to such a method can be found in an Internet search except in conjunction with problems similar to this one.
A method that can be used to find a first approximation of a square root is linear interpolation between the roots of adjacent perfect squares. For this, ...
• find the perfect squares of the consecutive integers that lie on either side of the root of interest
• form the ratio of difference between the number and the smaller square and the difference between the squares
• add this ratio to the smaller of the two integers to get an approximation of the root.
In this case, the square root of 96 lies between 9² = 81 and 10² = 100. The ratio of interest is (96 -81)/(100 -81) = 15/19. The approximate square root of 96 is then ...
√96 ≈ 9 + 15/19 ≈ 9.8
_____
If a = floor(√n), then this approximation to the root can be written as
√n ≈ a + (n -a²)/(2a+1)
If we define b = n - a², this looks like √n ≈ a + b/(2a+1). The approximation can be refined by replacing the 1 in the denominator with (b/(2a+1)). Repeately doing this replacement results in a "continued fraction" that converges to √n as more layers are added.
Answer:
2.25 (2 1/4) this is what i got for the answer to the division problem.
Step-by-step explanation:
sorry if i am wrong
Answer:
A) 48.8
Step-by-step explanation:
the mean is: sum of all terms divided by number of terms
49 + 37 + 41 + 54 + 63= 244
244/ 5= 48.8
Step-by-step help:
399 - 75 = 324.
Now that we have the bonus out of the equation, the fraction is approximately
324/12.
Divide by 2,
162/6
Divide by 2 again,
81/3.
81 divided by 3 is 27.
So,
The answer is exactly 27.
Hope that helped!
I think maybe the first or second number line.
Part C:
y = total cost
M = minutes
You can talk on the phone only 100 minutes per month
Company A:
y = 0.04M + 5
y = 0.04(100) + 5
y = 4 + 5
y = 9 $9 per month
Company B:
y = 0.10M + 2
y = 0.10(100) + 2
y = 10 + 2
y = 12 $12 per month
Company A offers the best deal because at Company A you have to pay $9 for 100 minutes per month, and at Company B you have to pay $12 for 100 minutes per month, so you have to pay $3 less.
Part D:
1.) With a budget of $30, Company A would allow me to talk longer on the phone. I know this because for Company A, you pay $3 less per month for the same amount of minutes as Company B. This means that I will save more money with Company A, and I can buy more minutes. (something like this)
