A rectangular folder has a perimeter of 30 inches and an area of 54 square inches. What are the dimensions of the folder?

1 answer:

3 0

We know, perimeter = 2(l + w)
So, 2(l + w) = 30
2l + 2w = 30
Divide the equation 2,
l + w = 15

Now, Area = l * w
l * w = 54

Substitute the value of l from previous equation,
(15-w) * w = 54
15w - w² = 54
w² - 15w + 54 = 0
w² - 6w - 9w + 54 = 0
w(w - 6) -9(w - 6) = 0
(w-6)(w-9) = 0
w = 6 or 9

In short, Your Dimensions would be: 6 × 9 in

Hope this helps!

lina2011 [118]

Answer:

Option B is correct that is the amount she is getting per bottle is $0.15

Step-by-step explanation:

We have been given the information that Melisande collected 14 bottles on Saturday and 9 bottles on Sunday

That means she has collected a total of 23 bottles

Let us assume that the amount she is paid for recycling is $b

Since she is left with $3.20 after the amount she gets for bottles we will get the equation below:

23b=3.20

Now, since she has to pay a one-time service fee equation will become

23b -0.25 =3.20

After simplification, we will get

23b=3.20+0.25=3.45

b=3.45/23=.15

b=$0.15

Therefore, The amount she is getting per bottle is $0.15

HOPE THIS HELPS :)

If you know the sine value for a given angle, how can you quickly find the cosecant value for that same angle?

pogonyaev

Answer:

See below

Step-by-step explanation:

Remember the quotient identity $\csc\theta=\frac{1}{\sin\theta}$ , so you need to take the reciprocal of the sine value for the given angle in order to get the cosecant value for that same angle.
