Multiply 44580 by .47
that gives you 20952.6 which equals 47% of the water
take the 44580, and subtract the 20952.6
giving you the remainder as your answer
23627.4
Answer:
Option C. Anna and Sara
Step-by-step explanation:
<u><em>The complete question in the attached figure</em></u>
Let
h ----> the minimum height h in inches necessary to ride a certain roller coaster
we have

The solution for this inequality is the interval [48,∞)
so
The value of h must be greater than or equal to 48 inches
<u><em>Verify who can ride the roller coaster</em></u>
1) Miguel 42 in
substitute the value of h in the inequality
----> is not true
therefore
Miguel can't ride the roller coaster
2) Patrick 45 in
substitute the value of h in the inequality
----> is not true
therefore
Patrick can't ride the roller coaster
3) Anna 48 in
substitute the value of h in the inequality
----> is true
therefore
Anna can ride the roller coaster
4) Sara 52 in
substitute the value of h in the inequality
----> is true
therefore
Sara can ride the roller coaster

so, that function is "defined", ok, what values of "x" are not in the domain, namely, what values can "x" take on and not make the function "undefined", well, you know, if we end up with a 0 at the denominator, like

then, we'd have an "undefined" expression...so... any values of "x" that make the denominator 0, are not really the ones we want, and thus they'd be excluded from the domain.
so, hmm which are those? let's check, let's set the denominator to 0, and solve for "x".
Answer:
s<12
Step-by-step explanation:
It didn't say there are "at most", it said there are fewer, so 12 is not included.
W+d=869
w=d-81
plug in
(d-81)+d=869
2d-81=869
+81 both sides
2d=950
÷2 both sides
d=475
dryer cost $475
let's check w=475-81
w=394
475+394=869
869=869
the solution is true :)
