Using the area of a rectangle, it is found that 35 bags are needed to cover the rectangular lawn.
What is the area of a rectangle?The area of a rectangle of length l and width w is given by the multiplication of the measures, that is:
A = lw
In this problem, we have that the measures in feet are l = 360, w = 190, hence the area in square feet is given by:
A = 360 x 190 = 68,400.
The number of bags is then given by:
68,400/2,000 = 34.2
Rounding up, 35 bags are needed to cover the rectangular lawn.

Gary and Jessica exercise for a total of 18 hours per week. Jessica exercises 2 less than 3 times the hours that Gary exercises. How many hours per week does Gary exercise?
Enter your answer in the box.
Work Shown:
g = number of hours that Gary exercises
3g-2 = number of hours that Jessica exercises
(g) + (3g-2) = 18
4g-2 = 18
4g = 18+2
4g = 20
g = 20/4
g = 5

Answer:
$13.10 represents the rate of change
Step-by-step explanation:
13.1 is the only value in the equation with a variable (g). There is an additional $13.10 charge for every gigabyte used over the limit, and this is the rate of change.
For example, if 5 gigabytes were used over the limit, the charge would be 13.1(5) or $65.50

Why is not the term perimeter used instead of circumference?
Answer:
Both words are used to talk about how long the boundary is of a 2D figure. Think of circumference as a special case of finding the perimeter. The term circumference refers to the perimeter of a figure without sides or something like a circle or arc.
So if we were to look at a rectangle and try to determine how long the boundary is we would use perimeter. On the other hand, if we have a circle we have no way to track how long each side is therefore we use circumference.
Perimeter is a wide term which means the total length of the surrounding (lines ) of the 2D figure.
circumference is the special case of the perimeter in which perimeter of Arc or circular lines are taken in count .

8-7=1A rectangle has a length of (2x+1) units, a width of (x-7) units and an Area of 17 square units. Find the dimensions of the rectangle.
✭ Explanation -:In this question we are provided with the length of a rectangle (2x + 1) units and the width of the rectangle (x - 7). It is also given that the area is 17 units². We are asked to calculate the length and width of the rectangle.
First we will find the value of x
We know,
[tex] \bull \: \small\boxed{ \rm{ Area_{(rectangle)} = Length × Width}}[/tex]
Substituting the values we get
[tex] \small\sf{ (2x + 1 ) (x - 7) = 17}[/tex]
[tex] \small\rm{ 2x( x - 7) + 1(x - 7) = 17}[/tex]
[tex] \small\rm{ 2 {x}^{2} - 14x + 1(x - 7) = 17}[/tex]
[tex] \small\rm{ 2 {x}^{2} - 13x - 7 = 17}[/tex]
[tex] \small\rm{2 {x}^{2} - 13x - 7 - 17 = 0 } [/tex]
[tex] \small\rm{2 {x}^{2} - 13x - 24 = 0} [/tex]
[tex] \small\rm{x = \dfrac{13 + 19}{2 \times 2} } [/tex]
[tex] \small\rm{ x = \dfrac{32}{4} = 8}[/tex]
[tex] \small\sf{x = 8} [/tex]
Now we will substitute the value of x
Length = (2x + 1) = 2 × 8 + 1 = 16 + 1 = 17 units
Width = (x - 7) = 8 - 7 = 1 units
Hence, the length of the rectangle is 17 units and the width is 1 units.which equation represents a linear function 2ry+y= 9 , y=12r-5 , 3y+r2+t=0, 4r+2(y-1)=0
The equation which represents a linear function for the variable y is y=12r-5. Option B is the correct option.
What is linear function?Linear function is the function in which the highest power of the unknown variable is one. Linear functions are used to model the real life problem in the mathematical expressions.
The linear function with dependent variable y and independent variable x can be written as,
y=mx+c
Here, m is the slope of the line represented by the function and c is the y intercept.
The equation given in the problem are,
2ry+y= 9
y=12r-5
3y+r2+t=0
4r+2(y-1)=0
The second option is similar to the standard linear function.
Hence, the equation which represents a linear function for the variable y is y=12r-5. Option B is the correct option.

1.) .30
2.) .34
3.) .02
4.) .26
The Venn probability that a a day in early March would have either rain or snow is given by:
4.) .26
What is a Venn probability?In a Venn probability, two non-independent events are related with each other, as are their probabilities.
The "or probability" is given by:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
In this problem, we have that the probabilities are given as follows:
[tex]P(A) = 0.18, P(B) = 0.12, P(A \cap B) = 0.04[/tex]
Hence:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
[tex]P(A \cup B) = 0.18 + 0.12 - 0.04[/tex]
[tex]P(A \cup B) = 0.26[/tex]
Which means that option 4 is correct.

Line segment st is dilated to create line segment s't' using the dilation rule dq,2.25. point q is the center of dilation. line segment s t is dilated to create line segment s prime t prime. the length of q t is 1.2 and the length of q s is 2. the length of s s prime is x and the length of t t prime is 1.5. what is x, the distance between points s' and s? x = 2.25 units x = 2.5 units x = 4.25 units x = 4.5 units
The value of x when the line segment st is dilated to create line s't' about point q is 2.5 units
How to determine the value of x?The given parameters are:
qs = 2
qt = 1.2
tt' = 1.5
ss' = x
To calculate the value of x, we make use of the following equivalent ratio
ss' : qs = tt' : qt
So, we have:
x : 2 = 1.5 : 1.2
Express as fractions
x/2 = 1.5/1.2
Multiply both sides by 2
x = 2 * 1.5/1.2
Evaluate the product
x = 2.5
Hence, the value of x is 2.5 units
