Answer:
See below
Step-by-step explanation:
- <em>There is a formula for estimating square root of non-perfect square numbers</em>
- <em>√(A²±B) = A ± B/2A</em>
- <em>where A² is the nearest perfect square, B is the difference between the original number and the perfect square</em>
<u>Examples</u>
- 1) √75 = √(8²+11) = 8 + 11/(2*8) = 8 + 11/16 = 8.6875
- 2) √114 = √(11² - 7) = 11 - 7/(2*11) = 10.6818
X - number of dimes, y - number of quarters
x + y = 11
0.10 x + 0.25 y = 1.70
0.10 x + 0.25 ( 11 - x ) = 1.70
you can solve it:
0.10 x + 2.75 x - 0.25 x = 1.70
0.15 x = 1.05
x = 1.05 : 0.15
x = 7 ( a boy has 7 dimes and 4 quarters )
Answer: 0.10 x + 0.25 ( 11 - x ) = 1.70
Answer: Slope= undefined because it's just a straight line across and the Y intercept is -6 because thats where Y is at when X is 0
Answer:
first make all seperate and find out the commons
