The water in a reservoir decreased by 47% during a drought. Before the drought, the reservoir held 44,580 acre ft (AF) of water.

yawa3891 [41]

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

The inequality h > 48 represents the minimum

inessss [21]

Answer:

Option C. Anna and Sara

Step-by-step explanation:

The complete question in the attached figure

Let

h ----> the minimum height h in inches necessary to ride a certain roller coaster

we have

$h\geq 48$

The solution for this inequality is the interval [48,∞)

The value of h must be greater than or equal to 48 inches

Verify who can ride the roller coaster

1) Miguel 42 in

substitute the value of h in the inequality

$42\geq 48$ ----> is not true

therefore

Miguel can't ride the roller coaster

2) Patrick 45 in

substitute the value of h in the inequality

$45\geq 48$ ----> is not true

therefore

Patrick can't ride the roller coaster

3) Anna 48 in

substitute the value of h in the inequality

$48\geq 48$ ----> is true

therefore

Anna can ride the roller coaster

4) Sara 52 in

substitute the value of h in the inequality

$52\geq 48$ ----> is true

therefore

Sara can ride the roller coaster

How do I solve this

anastassius [24]

$\bf \cfrac{x+2}{x^2+6x-7}$ 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 $\bf \cfrac{x+2}{0}$ 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".

$\bf x^2+6x-7=0\implies (x+7)(x-1)=0\implies x=
\begin{cases}
-7\\
1
\end{cases}
\\\\\\
\textit{let's check, } x=-7\quad \cfrac{(-7)+2}{(-7)^2+6(-7)-7}\implies \cfrac{-5}{49-42-7}\implies \cfrac{-5}{0}
\\\\\\
x=1\quad \cfrac{(1)+2}{(1)^2+6(1)-7}\implies \cfrac{3}{1+6-7}\implies \cfrac{-3}{0}$

A washer and dryer cost $869 combined. The washer cost $81 less than the dryer. What is the cost of the dryer?

marysya [2.9K]

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 :)
