Your friend says that 14.5% is equivilent to 14.5

14.5% is not equivilent to 14.5 because 14.5% is a part of the whole 1 or 100%. 14.5 is greater than one so that is incorrect.

To find the equivilent you divide the percent by 100 since it is part of 100 and it is a fraction of 14.5/100.

14.5/100 is 0.145 which is the equivilent.

That statement is incorrect. When writing a percentage as a decimal, the decimal point goes before the tens place, like so: .145

The area of a rectangular wall of a barn is 45 square feet. Its length is 12 feet longer than the width. Find the length and wid
ValentinkaMS [17]

Answer:

Mark as brainliest

Step-by-step explanation:

by using the formula for area:  A= L x W  substitute in what you know:   A = 54  , the length in terms of the width so use

 

L=12 + 2W.

 

Now when everything is plugged in you now have:  54 = (12 + 2W) x W  

 

Then use the Distributive Property to simplify:   54 = 12W + 2W2

 

Since you know have a quadratic to solve get it in the form  ax2+bx + c = 0 so that you can solve it:

 

You do this by subtracting 54 from both sides and putting the 2W2 first so now it looks like this:

 

2W2 + 12W -54 = 0

 

Using the quadratic formula where a =2, b = 12, and c = -54.

 

Find b2-4ac which is the discriminant:

 

(12)2-4*2*(-54)=576

 

Take the square root of 576= 24

 

Now substitute the rest of the values into the Quadratic Formula:

 

It will look something like this:   W = (-b plus or minus the square root of the discriminant)/2a

 

The two possible answers are:    

 

W = (-12 + 24)/4      and  W = (-12 - 24)/4

 

W = 12/4= 3            and W = -36/4= -9     (This second answer isn't possible because length can't be negative)

 

So the answer is:

 

Width = 3 feet        Length = 12 + 2W = 12 + 2*3= 12 + 6 = 18 feet

 

This checks because A = L x W     and  54 = 18 x 3

if you spin the spinner twice what is the probability of spinning orange then brown? If you spin the spinner twice what is the p
Nesterboy [21]
Multiply the two probabilities together.
Probability of spinning orange: 2/6 or 1/3
Probability of spinning brown: 3/6 or 1/2.

1/3 * 1/2= 1/6
1/2 * 1/2= 1/4

Final answers: For q1= 1/6; For q2= 1/4

Choose the expression that represents a cubic expression<br> 2x + 11
Olin [163]

The correct answer is Option c which is the cubic expression is 4x³ − 3x² − 2x + 11

The correct question is as given below:-

Need help ASAP. Choose the expression that represents a cubic expression.

a. 2x + 11

b . −3x² − 2x + 11

c . 4x³ − 3x² − 2x + 11

d . 5x⁴ + 4x³ − 3x² − 2x + 11

<h3>What is an expression?</h3>

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

The polynomial having a degree of three is called the cubic polynomial which means that the maximum power of the polynomial will be three and the solutions will also be three.

Here in the option, we can see that the maximum power of the polynomial is three and it will have a maximum of three solutions.

The third-degree expression will be:-

E = 4x³ − 3x² − 2x + 11

Therefore the correct answer is Option c which is the cubic expression is 4x³ − 3x² − 2x + 11
