The garden must be at least 17 feet wide.
Let's use w to represent the garden's breadth.
The perimeter of a rectangle is given by the formula P = 2L + 2W, where L is the length and W is the width.
Assuming that the length is 11 feet, the expression for the perimeter can be written as follows:
P = 2(11) + 2w = 22 + 2w
The perimeter is stated to be at least 56 feet and not to exceed 76 feet. Hence, we can create the inequality shown below:
56 ≤ 22 + 2w ≤ 76
When we take 22 out of every aspect of the inequality, we get:
34 ≤ 2w ≤ 54
By multiplying every aspect of the inequality by 2, we obtain:
17 ≤ w ≤ 27
Thus, the garden must be at least 17 feet wide.

Find the largest angle of A PAM if m = 22in, p = 16in, a = 9in. Round to the nearest hundredth.
P(A) = 0.2, P(B) = 0.4, P(A U B) = 0.5, P(A n B) = ?
The probability of both independent events A and B happening together is P(A n B) = 0.1.
What is meant by probability?
An event's probability is a numerical representation of how likely it is that the event will take place. In mathematical notation, it is written as a number between 0 and 1, or as a percentage between 0% and 100%. The higher an event's probability, the more likely it is to occur. In a sample space, there is a probability of 1 for each event. The probability formula states that the ratio between the number of favourable outcomes and the total number of outcomes determines the likelihood that an event will occur. Sets are used in the terminology of probability theory. A set is a grouping of various things.
Given,
Probability of A, P(A) = 0.2
Probability of B, P(B) = 0.4
P(A U B) = 0.5
We are asked to find P(A n B)
Now we know,
P(A U B) = P(A) + P(B) - P(A n B)
Then,
P(A n B) = P(A) + P(B) - P(A U B) = 0.2 + 0.4 - 0.5 = 0.1
Therefore the probability of both independent events A and B happening together is P(A n B) = 0.1.

What are ratios?We can determine how much of one quantity is in the other by comparing two amounts of the same units and finding the ratio. Ratios can be divided into two groups. The part to whole ratio is one, and the part-to-part ratio is another. The part-to-part ratio illustrates the relationship between two separate entities or groupings.
In the questions given,
The ratios of the sides of the first triangle = 36/18

Out of 187 randomly selected adults in the United States who were surveyed, 82 exercise on a regular basis. Construct a 90% confidence interval for the proportion of all adults in the United States who exercise on a regular basis. Round to three decimal places.
The true proportion of all adults in the United States who exercise on a regular basis is between 0.384 and 0.493 with 90% confidence interval.
How to construct a confidence interval for the proportion?To construct a confidence interval for the proportion of all adults in the United States who exercise on a regular basis, we can use the formula:
CI = p ± z√(p(1-p)/n)
where:
p = proportion of the sample who exercise on a regular basis
n = sample size
z = z-score from the standard normal distribution corresponding to the desired level of confidence
Here, p = 82/187 = 0.4385 and n = 187.
A standard normal distribution table or calculator, or use the following formula:
z = invNorm((1 + C)/2)
where:
C = confidence level (expressed as a decimal)
invNorm() = inverse normal distribution function
For a 90% confidence level, C = 0.90, so:
z = invNorm((1 + 0.90)/2) = invNorm(0.95) ≈ 1.645
Substituting in the values, we get:
CI = 0.4385 ± 1.645√(0.4385(1-0.4385)/187) ≈ 0.384, 0.493
Therefore, we can say with 90% confidence that the true proportion of all adults in the United States who exercise on a regular basis is between 0.384 and 0.493, rounded to three decimal places.

A net of a building block is shown below what is the total surface area of the building block
The total surface area of the building block is therefore (4×l×w) + (2×(b×h)/2), which is equal to (2×l×w) + bh.
What is surface area?Surface area is the total exposed area of a three-dimensional object, including the object's base area and lateral area. It is the area of the surface or outer boundary of an object and is measured in units squared such as square meters or square centimeters. Surface area is an important concept in mathematics, physics, and engineering, as it is used to calculate the amount of material needed to construct an object.
The total surface area of the building block can be found by adding the area of the six faces of the block together. To calculate the surface area of the block, we first need to find the area of each face. The six faces of the building block are four rectangular faces and two triangular faces. The area of each rectangular face can be found using the formula A=l×w, where l is the length and w is the width. The area of each triangular face can be found using the formula A=(b×h)/2, where b is the base and h is the height.
By adding the area of each face together, the total surface area of the building block can be found. The total surface area is equal to the sum of the four rectangular faces plus the two triangular faces. The total surface area of the building block is therefore (4×l×w) + (2×(b×h)/2), which is equal to (2×l×w) + bh.

help!! Find the missing length and round it to the nearest tenth.
The length of the hypotenuse is approximately 6.7.
What is the Pythagorean theorem and how is it used to find the hypotenuse of a right triangle?
The Pythagorean theorem is a fundamental relationship in Euclidean geometry that relates the lengths of the sides of a right triangle. It states that the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
Mathematically, the Pythagorean theorem can be expressed as:
[tex]c^2 = a^2+ b^2[/tex]
where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.
Finding the missing length :
In the given problem, we are given the lengths of two sides of a right triangle, which are 3 and 6. We can use these values to find the length of the hypotenuse using the Pythagorean theorem:
[tex]h^2 = 3^2+ 6^2[/tex]
[tex]h^2 = 9 + 36[/tex]
[tex]h^2 = 45[/tex]
Taking the square root of both sides gives:
[tex]h = \sqrt{45}[/tex]
Using a calculator, we can simplify this to:
[tex]h \approx 6.7[/tex] (rounded to the nearest tenth)

Sarah fell behind 3 meters each lap.
What is Total distance?
Whole distance refers to the actual travel distance between the origin and destination locations of the item.
If Sarah was 15 meters behind Anna when Anna finished the race, and they both ran the same distance, we can divide the total distance by the number of laps they ran to find the distance they ran per lap:
Total distance = 5 laps
Distance per lap = total distance / number of laps = 5 laps / 1 = 5
So Sarah and Anna each ran 5 meters per lap. If Sarah fell behind the same number of meters during each lap, we can use a negative integer to describe the distance she fell behind each lap. The distance she fell behind each lap is:
-3 meters (since 3 meters + 3 meters + 3 meters + 3 meters + 3 meters = 15 meters, which is the distance by which she was behind when Anna finished the race).

11. Jenn bought 4 identical book
bags online for a total cost of
$95.65 including a flat ate of
$4.99 for shipping. Write an
equation to find the cost of each
book bag, b.
Answer:
Step-by-step explanation:
Let x be the cost of each book bag. Then, we can set up the following equation based on the information given:
4x + 4.99 = 95.65
Here, 4x represents the cost of the four identical book bags, and 4.99 is the flat rate for shipping. We add them up to get the total cost of $95.65.
To solve for x, we can first subtract 4.99 from both sides of the equation to isolate the term 4x on the left-hand side:
4x = 90.66
Then, we can divide both sides of the equation by 4 to solve for x:
x = 22.67
Therefore, each book bag costs $22.67.

Given AD = BC and AD || BC Prove: ABCD is a paralleologram
The response to the given question would be that As a result, we have demonstrated that ABCD's opposing sides are parallel, proving that ABCD is a parallelogram.
What is parallelograms?A simple quadrilateral with two sets of parallel sides is known as a parallelogram in Euclidean geometry. Both sets of opposite sides are parallel and equal in a particular type of quadrilateral known as a parallelogram.
We must demonstrate that the opposing sides of ABCD's parallelogram are parallel.
CBA = DAB (Alternate interior angles)
Alternative interior angles (ABD = BAC; ADC = CBD) (Alternate interior angles)
DCA = ACD (Alternate interior angles)
Considering that AD = BC, we also have:
A + B Equals A + C. (Also on both sides)
AD = BC
Think about the two pairs of sides that are diagonally opposed: AB and CD and AD and BC.
We have these for AB and CD:
Interior angles of a quadrilateral: DAB + ABD + BCD + CDA = 180°; CBA + BAC + ADC + DCA = 180°. (Substituting corresponding angles)
We may insert them in and simplify to get: since DAB = CBA and ABD = BAC.
BCD = ADC
As a result of having the same transversal CD and equal alternative interior angles, AD and BC are also parallel. As a result, we have demonstrated that ABCD's opposing sides are parallel, proving that ABCD is a parallelogram.
