A rectangular garden has a perimeter of 578 yds.
The length is one more than three times the width.
Find the dimensions of the garden.
Answer:
length = 217 ydwidth = 72 ydStep-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width
From the question
Perimeter = 578 yds
The statement
The length is one more than three times the width is written as
l = 1 + 3w
Substitute the expression into the above formula and solve for the width
That's
578 = 2(1 + 3w) + 2w
578 = 2 + 6w + 2w
8w = 576
Divide both sides by 8
w = 72
Substitute w = 72 into l = 1 + 3w
That's
l = 1 + 3(72)
l = 216 + 1
l = 217
Therefore the dimensions are
length = 217 yd
width = 72 yd
Hope this helps you
........Median vs mean?
The mean is affected by the skewness, whereas the median is not.
==================================
Let's go through the answer choices to see which are true and which are false.
A. True. The mean takes account of all the values since we sum all the values and divide by the number of values. The median only looks at the middle most value. The median does not take into account any other value. So the outliers can move wherever you want and the median will not be affected.B. False. It depends on what the context of the situation is. Both measures of center have their strengths and weaknesses. The median is only preferred if there are outliers. That way we get a sense of where the center is and know that the center isn't being pulled on by the outliers. A good example is home real estate as this problem mentions.C. False. The mean is larger than the median if the data is skewed right. Skewed right data means we have a large outlier(s) to the right side pulling the mean toward that location. An example would be having homes in some range of say 50 to 100 thousand, and then an outlier mansion would have a price of 20 million dollars. This skews the mean to be larger than it should be (when it should be somewhere between 50 and 100 thousand). Note: sometimes a trimmed mean is used instead of the medianD. False. The mean should only be used if we don't have any outliers at all. In other words, the mean should only be used if the data is not skewed left and not skewed right either. E. False. This computes the midrange and not the median. In my experience with many stats problems, the midrange doesn't really come up that often. Though I could just have a limited viewpoint of course.Mak deposited $493.12 in a savings account that earns 3.2% simple interest. What is Mak's account balance after 13 years?

Step-by-step explanation:
Graph the systems of equations. Then analyze the graph for the intersection. The point of intersection will be your solution set.
Answer:
[tex]x = -2\\y = -4[/tex]
Step-by-step explanation:
Question
[tex]\left \{ {{-2x + 2y = -4} \atop {3x + 3y = -18}} \right.[/tex]
Multiply throughout the equation to eliminate a variable:
[tex]-2x + 2y = -4[/tex] becomes [tex]-6x + 6y = -12[/tex] when multiplied by 3
[tex]3x + 3y = -18[/tex] becomes [tex]6x + 6y = -36[/tex] when multiplied by 2
Then add the values of the variables together:
[tex]-6x + 6x = 0\\6y + 6y = 12y \\-12 - 36 = -48[/tex]
And a new equation forms:
[tex]0 + 12y = -48[/tex]
[tex]y = -4[/tex]
Plug in [tex]y[/tex] to any of the previous equations to solve for [tex]x[/tex] :
[tex]-2x + 2y = -4[/tex]
[tex]-2x + 2(-4) = -4[/tex]
[tex]-2x - 8 = -4[/tex]
[tex]-2x = 4[/tex]
[tex]x = -2[/tex]

Option (2)
Step-by-step explanation:
If m(x) and n(x) are the functions inverse of each other,
Then the following condition should be fulfilled,
m[n(x)] = n[m(x)] = x
Here, m(x) = [tex]\frac{3x}{x+7}[/tex] and n(x) = [tex]\frac{7x}{3-x}[/tex]
m[n(x)] = [tex]\frac{3(\frac{7x}{3-x})}{(\frac{7x}{3-x})+7}[/tex]
= [tex]\frac{21x}{7x+21-7x}[/tex]
= x
n[m(x)] = [tex]\frac{7(\frac{3x}{x+7})}{3-\frac{3x}{x+7}}[/tex]
= [tex]\frac{21x}{3x+21-3x}[/tex]
= x
Therefore, [tex]\frac{3(\frac{7x}{3-x})}{(\frac{7x}{3-x})+7}=\frac{7(\frac{3x}{x+7})}{3-\frac{3x}{x+7}}=x[/tex] will be the correct option.
Option (2) will be the answer.

The pairs 3, 12 and 4, 9 are factor pairs of which number? A) 32 B) 36 C) 44 D) 82
Answer:
When factorizing one number, what you get are other numbers that, when they get multiplied, the result of the product is the first number.
In our case, the pair of 3, 12 and the pair of 4, 9 are factors of 36, as it's the number we get when multiplying them:
3 * 12 = 364 * 9 = 36We can factroize 36 like this: 2*2*3*3, and:
2 = 24 = 2*29 = 3*312 = 2*2*3The factor pairs belong to the number 36.
What is factorization?The breaking or decomposition of an entity (such as a number, a matrix, or a polynomial) into a product of another entity, or factors, whose multiplication results in the original number, matrix, etc., is known as factorization or factoring in mathematics.
As per the given data:
The factor pairs are as follows:
3, 12
4, 9
We have to find out that of which number these factor pair belongs.
When the factors of any number are multiplied with each other, we get that number.
For finding out the number, we need to multiply the factor pairs:
3 × 12 = 36
4 × 9 = 36
The factor pairs belong to the number 36.
Hence, The factor pairs belong to the number 36.

If -2(3y+5)= -4, find the value of 5y.
Answer:
5y = -5
Step-by-step explanation:
-2(3y+5)= -4
Divide each side by -2
-2/ -2 (3y+5)= -4/-2
3y+5 = 2
Subtract 5 from each side
3y +5 -5 = 2-5
3y = -3
Divide by 3
3y/3 = -3/3
y = -1
5y = 5*-1 = -5
Taylor has 18 cents in dimes and nickels in her pocket. The number of dimes is four more than the number of nickels. How many of each coin does it have?
Answer:
Explained below.
Step-by-step explanation:
The value of different types of coins are as follows:
1 penny (p) = 1 cent
1 nickel (n) = 5 cents
1 dime (d) = 10 cents
1 quarter (q) = 25 cents
It is provided that Taylor has 18 cents in dimes and nickels in her pocket.
This is not possible.
Because the sum of any number of dime and nickel coins will always be a multiple of 5.
a·d + b·n = 10a + 5b = 5 (2a + b)
The value 18 cents can be formed as follows:
8p + d = 18 cents
3p + n + d = 18 cents
3n + 3p = 18 cents
Evaluate the expression if a = 3 over 4, b = -8, c = -2, and d = 3
Answer:
45
Step-by-step explanation:
So we have the expression:
[tex]ab^2-d[/tex]
And we want to evaluate it for a=3/4, =-8, and d=3.
Thus, substitute in these values:
[tex]=(\frac{3}{4})(-8)^2-3[/tex]
Do the exponent first. -8 squared is positive 64:
[tex]=(\frac{3}{4})(64)-3[/tex]
And 3/4 times 64 is 48:
[tex]=(48)-3[/tex]
Subtract:
[tex]=45[/tex]
I am a 4 digit number my one digit is 2 my tens digit is 4 times greater then my ones my hundreds and thousands digits are both 3 greater then my ones what number am i
Answer:
6682
Step-by-step explanation:
So we have a 4 digit number and we need to find all the digits of it.
First, we are told that the one digit is 2. So the number is xxx2
Now, we know that the tens digit is 4 times greater than the ones, thus, the tens digits is 4 times 2, this is 4(2) = 8. Thus, the tens digit is 8 and the number is xx82.
Finally we know that the hundreds and thousands are both 3 times greater than the ones, so the digits are 3(2) = 6. Thus the hundreds and thousands are 6 and the final number is 6682.

4 = 3/4m - 6 pls help me ASAP and check the answer
Answer:
m = 3/40
Step-by-step explanation:
4 = 3/4m - 6
m*4 = m(3/4m -6)
4m = m*3/4m + m*-6
4m = 3/4 - 6m
6m + 4m = 3/4
10m = 3/4
m = (3/4)/10
m = 3/40
check:
4 = 3/(4*3/40) - 6
4 = 3/(12/40) - 6
4 = (3*40)/12 - 6
4 = 120/12 - 6
4 = 10 - 6

What is quadrilateral?A quadrilateral is a four-sided polygon. The sum of the interior angles of a quadrilateral is always equal to 360 degrees. There are several types of quadrilaterals, including: Square, rectangle, parallelogram, rhombus, trapezoid, and kite.
Length of side PS can be calculated using the distance formula,
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Where,
P(-2, 5) = ([tex]x_1,y_1[/tex]) (the coordinate of P is gotten from the graph).
Given that,
S(9, 5) = ([tex]x_2,y_2[/tex])
PS = [tex]\sqrt{(9-(-2))^2+(5-5)^2}[/tex]
PS = [tex]\sqrt{11^2+0^2}[/tex]
PS = [tex]\sqrt{121}[/tex]
PS = 11units.
Thus, the answer is 11 units.
