First get the same denominator 2/5=4/10 so from here do 7/10-4/10 the denominator stays the same and the numerator changes, 3/10 is the answer so Heather live 3/10 of a mile closer to the library than the school
Answer:
The new width is 3 in.
Step-by-step explanation:
We can use the ratio of w/h, the origal width and height should have the same ratio as the new width and height.
<u>12 </u>= <u>x</u>
16 4
Then solve for x:
x = 4 (12/16)
x = 3
To check:
12/16 = 3/4
3/4 = 3/4
Answer:
$0.39 per bag
Step-by-step explanation:
$14.04 ÷36 = $0.39 per bag
15ft because 12x.25=3 so 3ft is 25% of the 12ft, add the 3+12=15
<h3>Explanation:</h3>
Any techniques that you're familiar with can be applied to polynomials of any degree. These might include ...
- use of the rational root theorem
- use of Descartes' rule of signs
- use of any algorithms you're aware of for finding bounds on roots
- graphing
- factoring by grouping
- use of "special forms" (for example, difference of squares, sum and difference of cubes, square of binomials, expansion of n-th powers of binomials)
- guess and check
- making use of turning points
Each root you find can be factored out to reduce the degree of the remaining polynomial factor(s).
