System of equations:
w=(3/2)*h          (1)
w*h=54      area (2)

w=54/h substitute into (1)
54/h=3h/2
3h²=54*2
h²= 36  (we take only positive solution)
h = √36=6
h=6 in.
w=(3/2)*h=(3/2)*6= 9
w=9 in.
correct answer is D

5700 is compounded semiannually at a rate of 15% for 12 years
Rama09 [41]

Answer:

$32,335.38

Step-by-step explanation:

You are going to want to use the compound interest formula, which is shown below.

P(1+\frac{r}{n} )^{nt}

<em>P = initial balance </em>

<em>r = interest rate </em>

<em>n = number of times compounded annually </em>

<em>t = time</em>

<em />

Now lets plug in the values into the equation:

5,700(1+\frac{.15}{2})^{12(2)} = 32,335.38

Your answer is $32,335.38

How can using equivalent ratios help you operate a business?
never [62]
Hi there

Using equivalent ratios to help operate a business is useful for financial ratios.
There are common size ratios, liquidity ratios, efficiency ratios, and solvency ratios. 

Ratios are used to let us compare one item to another. (For example, comparing 1 teacher to 25 students, or 1:25)

Did you have any answers to chose from? I just figured I'd provide you with what I knew about this subject to help in case there were no options to chose from.

Based on a survey, that 46% of consumers are comfortable having drones deliver their purchases. Suppose that we want to find the
Wewaii [24]

n=5,x=3,p=0.46,q=0.54 .

<u>Step-by-step explanation:</u>

Here we have , Based on a survey, that 46% of consumers are comfortable having drones deliver their purchases. Suppose that we want to find the probability that when five consumers are randomly selected, exactly three on them are comfortable with delivery by drones. We need to find the values of n,x,p,and q .Let's find out:

According to question , 46% of consumers are comfortable having drones deliver their purchases , So , Probability of success :

⇒ p=0.46

And , probability of failure :

⇒ q=1-p =1-0.46

⇒ q=0.54

Now , n = Number of people randomly selected = 5

x = Number of people exactly comfortable = 3

Therefore , n=5,x=3,p=0.46,q=0.54 .

Solve the qn in attachment .​
galina1969 [7]

Answer:

\implies \dfrac{ -4x+7}{2(x-2) }

Step-by-step explanation:

The given expression to us is ,

\implies \dfrac{\frac{ 3}{x-1} -4 }{ 2 -\frac{2}{x-1}}

Now take the LCM as ( x - 1 ) and Simplify , we have ,

\implies \dfrac{\frac{ 3 -4(x-1) }{x-1} }{ \frac{2-2(2x-1)}{x-1}}

Simplifying further , we get ,

\implies \dfrac{ -4x+7}{2(x-2) }

<u>Hence the second option is correct.</u>
