A gardener is planning to fill her garden with mulch. she plots it on a grid to plan how much she will need. the garden is in the shape of a rectangle with vertices at (3, 9) (5, 9) (3, 3) (5, 3). one bag of mulch covers 5ft^2 and costs $5.00. how much will it cost her to cover her garden?
The cost to cover the garden with mulch will be $12.00, as the area of the rectangular garden is 12 ft.².
The cost of one bag of mulch is given as $5.00.
The area covered by one bag of mulch is 5 ft.².
Therefore, the cost to cover 1 ft.² of the garden with mulch is $(5/5) = $1.00.
To find the area of the rectangular plot representing the garden, we do the follows:
The distance formula between two points (x₁, y₁) and (x₂, y₂) is,
d = √((x₂ - x₁)² + (y₂ - y₁)²).
The length of the rectangular plot between points (3, 9) and (5, 9):
Length = √((5 - 3)² + (9 - 9)²) = √(2² + 0²) = √(4) = 2.
The width of the rectangular plot between the points (3, 3) and (3, 9):
Width = √((3 - 3)² + (9 - 3)²) = √(0² + 6²) = √(36) = 6.
Therefore, the area of the rectangular plot = Length*Width = 2*6 = 12 ft.².
Therefore, the cost to cover the rectangular plot with mulch, at the cost of $1.00 per 1 ft.² = $1*12 = $12.00.
Therefore, the cost to cover the garden with mulch will be $12.00, as the area of the rectangular garden is 12 ft.².

Answer:
3rd graph from the top.
Step-by-step explanation:
It can't be the top one because the kids shoulder doesn't start at the ground.
It can't be the second or fourth because it shows him not waiting in line.
Therefore it must be the 3rd!
Answer: 3rd option
Step-by-step explanation:
Because the description says that it starts not at 0(from the kid's shoulder), the 1st and 4th options are out.
2nd option is incorrect because the kid had to stand in line so the shoulder height doesn't change(unless he was picking stuff up or something)

Which statement about the function is true?
O The function is increasing for all real values of x
where
x<-4.
Answer:
A.) The function is increasing for all real values of x where x < -4
Step-by-step explanation:
On the interval x < -4, all of the x values are increasing. Before x = -4, the line assumes a positive slope because it is heading upwards. After this interval, the function is decreasing because the slope is heading downwards.
On the interval -6 < x < -2, all of the x values are positive because they lie above the x-axis. This does not necessarily mean that all of the values are increasing.
On the interval x < -6 and x > -2, all of the x values are negative because they lie below the x-axis.

Can someone help me with question 3? it geometry, gotta need an answer fast
Answer:
Step-by-step explanation:
So for the 1st one you're going to use your protractor and line it up so that BC is at 0 degrees, that way you can look at the point A to determine the angle. Now that you have the angle you're going to take your protractor and draw one point which will be where the two lines meet, line this up in the middle and then draw a point at 0 degrees and a point at the angle you found. Now draw another point at half the angle (like in the previous answer I answered). Draw a line from the middle point and connect it to all these three points (4 in total but one of them is going connected to all of them, like the point B in the image you sent).
For the second question you're going to take the angle you found in the first answer and multiply it by 2. Now start off by drawing a middle point which will connect the two other lines. Line up your protractor so that point is at bottom but in the middle (Check my photo for clarification). Now go to the value that is twice the angle and draw a point there, and also draw a point at 0 degrees) and then connect the two points to the middle point.
For question 3 you don't really need the hint, all you need is to multiply the angle by 1.5 but I'll send another image explaining what it's trying to explain.
Explain why statistical acceptance sampling is not an effective method for monitoring process quality.
Acceptance sampling is a statistical method used to monitor the quality of purchased parts and components. To ensure the quality of incoming parts, a purchaser or manufacturer normally samples 20 parts and allows one defect.
a) Concerned with inspection of products
b) Concerned with decision making regarding products
c) One of the oldest aspects of quality assurance
The Acceptance sampling procedure is necessarily a lot sentencing procedure. It cannot be used to estimate the lot quality or lot conformity to the standard specifications.
The acceptance sampling is used when the test is destructive, or the cost of 100% inspection is quite high, or when we need a continuously monitoring program
The Acceptance sampling procedure is used for decision making of either acceptation or rejection of a lot. It can’t be used as a lot quality estimator
As Acceptance sampling is just a lot sentencing process, it can’t estimate the quality of products in the lot. But designed experiments ensure good quality of the process output before even production

• Here The sample space S is the set of possible outcomes (ordered pairs of marbles) that we can draw at random (without replacement) from the bag.
Then
[tex]\text{cardS} =P^{2}_{10}=10\times 9=90[/tex]
……………………………………………
Drawing two marbles where the marbles are different colors
means
drawing (1green ,1 yellow) or (1green ,1 red) or (1yellow ,1 red)
Remark: the order intervene
=========================
•• Let E be the event “Drawing two marbles where the marbles are different colors”.
CardE = 2×3×3 + 2×3×4 + 2×3×4 = 66 (2 is for the order)
Conclusion:
[tex]p\left( E\right) =\frac{66}{90} =\frac{11}{15} =0.733333333333[/tex]

Answer:
[tex]\sf \dfrac{11}{15}[/tex]
Step-by-step explanation:
The bag of marbles contains:
3 green marbles3 yellow marbles4 red marbles⇒ Total marbles = 3 + 3 + 4 = 10
Probability Formula
[tex]\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}[/tex]
First draw
[tex]\implies \sf P(green)=\dfrac{3}{10}[/tex]
[tex]\implies \sf P(yellow)=\dfrac{3}{10}[/tex]
[tex]\implies \sf P(red)=\dfrac{4}{10}[/tex]
Second draw
As the first marble is not replaced there are now 9 marbles in the bag.
If the first marble was green, the probability of drawing a yellow is now 3/9 and the probability of drawing a red is now 4/9.
If the first marble was yellow, the probability of drawing a green is now 3/9 and the probability of drawing a red is now 4/9.
If the first marble was red, the probability of drawing a green is now 3/9 and the probability of drawing a yellow is now 3/9.
To find the individual probabilities of picking 2 different colors, multiply the probability of the first draw by the probability of the second draw:
[tex]\implies \sf P(green)\:and\:P(red)=\dfrac{3}{10} \times \dfrac{4}{9}=\dfrac{12}{90}[/tex]
[tex]\implies \sf P(green)\:and\:P(yellow)=\dfrac{3}{10} \times \dfrac{3}{9}=\dfrac{9}{90}[/tex]
[tex]\implies \sf P(yellow)\:and\:P(green)=\dfrac{3}{10} \times \dfrac{3}{9}=\dfrac{9}{90}[/tex]
[tex]\implies \sf P(yellow)\:and\:P(red)=\dfrac{3}{10} \times \dfrac{4}{9}=\dfrac{12}{90}[/tex]

To find the probability of drawing two marbles at random and the marbles being different colors, add the individual probabilities listed above:
[tex]\begin{aligned}\implies \sf P(2\:different\:color\:marbles) &=\sf \dfrac{12}{90}+\dfrac{9}{90}+\dfrac{9}{90}+\dfrac{12}{90}+\dfrac{12}{90}+\dfrac{12}{90}\\\\ & = \sf \dfrac{66}{90}\\\\ & =\sf \dfrac{11}{15}\end{aligned}[/tex]

Answer:
The second choice.
Step-by-step explanation:
The length of AC must be equal to 5, since it is horizontally five units. We can rule out the first option.
Length BC cannot be the square root of 16, since that would be exactly 4 units. BC is slanted and does not represent a completely vertical line, so it is not a whole number. We can rule out the fourth option.
Length AB cannot be a whole number, being a slanted line that crosses a total of more than four units. Option three can be ruled out.
Therefore, we are left with the second option.
Answer:
AC = 5, BC = √17, AB = √32
Explanation:
Given points: A(-3, -2), B(1, 2), C(2, -2)
Use distance between two points formula:
[tex]\sf Distance \ between \ two \ points = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
AC length:
[tex]\sf d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{(2-(-3))^2 + (-2-(-2))^2} = \sqrt{25+ 0} = 5[/tex]
BC length:
[tex]\sf d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{(2-1)^2 + (-2-2)^2} = \sqrt{1 + 16} = \sqrt{17}[/tex]
AB length:
[tex]\sf d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{(-3-1)^2 + (-2-2)^2} = \sqrt{16 + 16} = \sqrt{32}[/tex]
Find the circumference and the area of a circle with diameter 6 ft.
Answer:
Circumference = 18.84 ft
Area = 28.26 ft squared
Step-by-step explanation:
C(circumference) = 2 x [tex]\pi[/tex] x r(radius)
radius = 1/2 circumference
1. divide circumference by two to get the radius, which would be three ft.
2. multiply the radius by pie (3.14) and then multiply that by two and you have your circumference, which is 18.84 ft
area = [tex]\pi[/tex] x r(radius)^2
1. find the radius squared, which would be 9 because 3^2 = 3 x 3 which = 9
2. multiply 9 by pie (3.14) and you get the area which = 28.26
How is copying segment similar to copying an angle ?
Answer:
Copying a line segment or angle is an illustration of transformation. Both are similar, because they are both rigid transformation.
When an angle is copied to a new angle, the new angle and the old angle will have the same measure
Similarly;
When a line segment is copied to a new segment, the new line segment and the old line segment will have the same measure
This type of transformation is referred to as a rigid transformation.
Hence, copying a line segment is similar to copying an angle, because they are both rigid transformations

A triangle is shown. One side has a length of 16, another side has a length of 20, and the length of the longest side is unknown.
Janice examines the given triangle and estimates that the longest side has a length of 25 units―if it is a right triangle. How does her estimate compare to the actual length?
It is exactly correct.
It is under by approximately 0.6 units.
It is over by approximately 0.6 units.
It is over by 13 units.
Janice estimate is under by approximately 0. 6 units. Option B
How to determine the estimateThe longest part is called the hypotenuse
The formula for finding the hypotenuse, we use the Pythagorean theorem
Hypotenuse = square root of both opposite square and adjacent square
We have that,
Hypotenuse = [tex]\sqrt{16^2 + 20^2}[/tex]
Hypotenuse = [tex]\sqrt{256+ 400}[/tex]
Hypotenuse = [tex]\sqrt{656}[/tex]
Find the square root
Hypotenuse = 25. 6
The length of the longest part = 25. 6
Janice estimated it to be 25
Comparing her estimate with the actual length = Actual length - estimate
⇒ 25. 6 - 25
⇒ 0. 6
Therefore, Janice estimate is under by approximately 0. 6 units. Option B

Kevin earned $80. Out of his earnings, he spent $68/5 on shopping, $51/2 on food, and $22/5 for taxi. Find the remaining amount.
The amount remaining out the money earned is $37.5
Sum of values and proportionGiven the following parameters
Amount earned by kevin = $80
If he spent $68/5 on shopping, $51/2 on food, and $22/5 for taxi, the total money spent is given as;
Total money spent = 51/2 + 68/5 + 22/5
Total money spent = 51/2 + 90/5
Total money spent = 25.5 + 18
Total money spent = 43.5
Amount remaining = 80. - 43.5
Amount remaining = 37.5
Hence the amount remaining out the money earned is $37.5
