The length of a new rectangular playing field is 6 yards longer than double the width. If the perimeter of the rectangular playing field is 294 yards what are the dimensions?
Answer:
width = 47
Length = 100
Step-by-step explanation:
The perimeter of the rectangle has the formula
P = 2(L + W)
P = 2L + 2W
Length = 6 yards longer than double it's width.
Mathematically,
length = 6 + 2W
We put this into the formula for perimeter
P = 2(6+2W)+2W
294 = 12+4W+2W
294 = 12+6W
Collect like terms
294-12 = 6W
282 = 6w
Divide through by 6
W = 282/6
W = 47
This is the width
Remember length = 6 + 2(W)
So
Length = 6+2(47)
= 6+94
= 100
Width = 47
L = 100
These are the dimensions

Answer:
Option 1, y = 3·x³ - 3 is not a linear function because the power of x is 3
Option 2 is a linear function of the form y = m·x + c, where m = 8.75 and c = 0
Option 3 is not a linear function because the power of x is -1 ≠ 1
Option 4 is a curved line graph and therefore is not a linear function
Option 5 is a linear function because the points of the graph are in a straight line
Option 6 is a linear function because the it has a straight line graph
Option 7 is a linear function because the "y" values has a common first difference of -15
Option 8 is not a linear function because the "y" values do not have a common first difference. (1 - 2) ≠ (2/3 - 1)
Option 9 is not a linear function because the data does not form a graph with a straight line
Option 10 is not a linear function because the dependent variable or "y" values which are the HEIGHT (YARDS) values, do not have a constant or common first difference (7.2 - 0) ≠ (10.7 - 7.2)
Step-by-step explanation:
A linear function is a function with a straight line graph and the general equation of a linear function is of the form, y = f(x) = m·x + c.
The linear function has one dependent variable, "y" and one independent variable "x" with the exponent of the x being the first power or one and the "y" values has a common first difference value
») If 5y = 25, which property of equality was used to
keep the equation 5y - 7 = 25 - 7 equal?
») Convince Me!
What other properties of equality could you apply to
keep the equation 5y = 25 equal? Give an example of
each.
Answer:
a. Subtraction property
b. Addition property and Multiplication property
Step-by-step explanation:
Given
[tex]5y = 25[/tex]
Solving (a): Which property is applied to [tex]5y-7 = 25-7[/tex]
The property applied is the subtraction property of inequality, and it states that:
If [tex]a = b[/tex]
Then
[tex]a - x = b - x[/tex]
So, in this case:
[tex]a = 5y, b = 25\ and\ x=7[/tex]
Solving (b): Other properties
1. The additive property of equality
If [tex]a = b[/tex]
Then
[tex]a + x = b + x[/tex]
So, the expression can be written as:
[tex]5y + 12 = 25 + 12[/tex]
When 12 is subtracted from both sides, the equation returns to the original
i.e.
[tex]5y + 12 - 12 = 25 + 12 - 12[/tex]
[tex]5y = 25[/tex]
2. The multiplication property of equality
If [tex]a = b[/tex]
Then
[tex]a * x = b * x[/tex]
So, the expression can be written as:
[tex]5y* 2 = 25 * 2[/tex]
[tex]10y = 50[/tex]
When both sides are divided by 2, the equation returns to the original
i.e.
[tex]\frac{10y}{2} = \frac{50}{2}[/tex]
[tex]5y = 25[/tex]

Su mei recipe for bean sald calls for 3 cans of lima beans 2 cans of pinto bean and 2 kidney renuin suppose she use 9 cans of lima beans how many cans of pianao veans will she use?How many cans of kidney beans will she use?
Answer: She will use 6 cans of pinto beans .
She will use 6 cans of kidney beans.
Step-by-step explanation:
As per given,
For bean salad : lima beans : pinto beans : kidney beans
= 3:2:2
Let quantity of lima beans = 3x, pinto beans 2x , kidney beans 2x.
if she use 9 cans of lima beans, then
3x=9
⇒x=9
Now, 2x= 2 x 3 =6
Thus , she will use 6 cans of pinto beans and 6 cans of kidney beans.

Answer:
he has 10 type of each coin
Step-by-step explanation:
Total number of cents in possession is calculated as;
= 25 + 10 + 5
= 40 cent
Total amount in possession = $4
= 400 cent
Since he has equal number of each cent, let this equal number be "y";
40cent (y) = 400cent
40y = 400
divide both sides by 40
[tex]\frac{40y}{40} = \frac{400}{40} \\\\y = 10[/tex]
Therefore, he has 10 type of each coin

Find x and y so the quadrilateral is a parallelogram
Answer:
Result
x = 7 y = 4Step-by-step explanation:
Given the parallelogram
Here are some of the properties of a parallelogram:
The opposite sides of a parallelogram are equal.The opposite angles of a parallelogram are equal.The diagonals of a parallelogram bisect each other.We know that the diagonals of a parallelogram bisect each other.
In our case, the diagonals PR and QS bisect each other.
Thus, we get
RT = TPGiven RT = x and TP = 5x-28, so
[tex]x = 5x-28[/tex]
[tex]5x-x = 28[/tex]
[tex]4x = 28[/tex]
divide boh sides by 4
[tex]4x/4 = 28/4[/tex]
[tex]x = 7[/tex]
Therefore, the value of x = 7Similarly, we can determine the value of y.
As
[tex]QT = TS[/tex]
Given QT = 5y and TS = 2y+12, so
[tex]5y = 2y+12[/tex]
[tex]5y-2y = 12[/tex]
[tex]3y = 12[/tex]
divide both sides by 3
[tex]3y/3 = 12/3[/tex]
[tex]y = 4[/tex]
Therefore, the value of y = 4Result
x = 7 y = 4Number of Days (cm)

Rewrite each linear inequality in slope-intercept form. Then graph the
solutions in the coordinate plane.
y - x< 3
Answer:
Slope intercept form is y < x+3
The graph is below
=====================================================
Explanation:
To get the inequality into slope intercept form, we add x to both sides getting y < x+3
Now let's graph y = x+3, which is the boundary line of the inequality.
This line has slope of 1 and y intercept 3. Two points on this line are (0,3) and (1,4). Make this boundary line a dashed line to indicate "points on the boundary are not part of the solution set"
We shade below the dashed boundary line due to the "less than" sign. You could also use a test point like (0,0) to see that it's part of the solution set, so that point is in the shaded region.
Refer to the graph below.

Suppose the radius of a circle is 3 units what is the circumference
Answer:
[tex]6\pi[/tex] or approximately [tex]18.85[/tex] units
Step-by-step explanation:
The formula for finding the circumference of a circle is [tex]C=2\pi r[/tex], where [tex]C[/tex] = circumference and [tex]r[/tex] = radius. In this case, [tex]r=3[/tex], so after plugging that into [tex]C=2\pi r[/tex], we get:
[tex]C=2\pi r\\ = 2*\pi *3\\=6\pi[/tex]
Since [tex]\pi[/tex] is approximately [tex]3.1415[/tex], [tex]6\pi =6*3.1415=18.849[/tex], which rounds to [tex]18.85[/tex]. Therefore, the circumference of the circle is [tex]6\pi[/tex], or approximately [tex]18.85[/tex] units. Hope this helps!
