The required width of the flower garden is 6 feet.

The area of a rectangular flower garden is 132 square feet.

Let us assume the length of the flower garden is l and its width is w (in feet).

The length of the flower is 10 feet more than twice the width of the garden.

That is, l = (10 + 2w ) feet

Thus the area of the flower garden is ,

length * width = 132 sq ft

⇒ (10+ 2w) w = 132

⇒2w^2 + 10w -132 = 0

⇒ w^2 + 5w - 66 = 0

⇒ w^2 + 11w - 6w - 66 = 0

⇒ w( w+ 11) - 6( w + 11) = 0

⇒ (w - 6)(w + 11) = 0

⇒ w = 6 and = -11

Since length or width of any garden can not be in negative, hence ignoring the negative value of w.

Thus, width of the flower garden is w=6  feet.

If p is a prime number and a is a positive integer, then pa has (a+1) distinct positive divisors.

A prime number is a positive integer greater than 1, which is divisible only by 1 and itself. Divisors are the numbers that evenly divide a given number.

For a prime number p raised to the power of a (p^a), the number of distinct positive divisors can be found using the following formula:

Number of divisors = (a + 1)

This is because each power of p from 0 to a can divide p^a without any remainder, giving us a total of a + 1 distinct divisors. These divisors are:

1, p, p^2, p^3, ..., p^(a-1), p^a

For example, if p = 2 (a prime number) and a = 3 (a positive integer), then the number of distinct positive divisors for 2^3 (which is 8) would be:

Number of divisors = (3 + 1) = 4

The divisors for 2^3 (8) are 1, 2, 4, and 8.

The greatest number of 27-inch pieces that she can cut from three pieces of ribbon is found to be 19. So, option B is the correct answer choice.

Each yard is equal to 36 inches, so 5 yards are equal to 180 inches. Therefore, each piece of ribbon is 180 inches long.

To find out how many 27-inch pieces Lucia can cut from each piece of ribbon, we divide 180 by 27.

180/27 = 6.67

Since Lucia can only cut whole pieces, she can cut 6 pieces of ribbon from each piece of ribbon.

The total number of monotonous positive integers either a strictly increasing or a strictly decreasing sequence is equal to 90.

Let us consider the cases of monotonous numbers with increasing digits and monotonous numbers with decreasing digits separately.

For a monotonous number with increasing digits, we can start with any digit from 1 to 9, and for each subsequent digit.

Choose any number from the set of remaining digits.

For example, if we start with 1, we have 8 choices for the second digit, 7 choices for the third digit, and so on.

Until we have only one choice left for the last digit.

There are a total of 9 + 8 + 7 + ... + 1 = 45 monotonous numbers with increasing digits.

For a monotonous number with decreasing digits, we can start with any digit from 9 to 1, and for each subsequent digit.

Choose any number from the set of remaining digits that is smaller than the previous digit.

For example, if we start with 9, we have only one choice for the second digit 8, one choice for the third digit 7, and so on.

Until we have only one choice left for the last digit.

There are a total of 9 + 8 + 7 + ... + 1 = 45 monotonous numbers with decreasing digits.

The number 0 cannot be the first digit of a monotonous number with increasing digits, because it is not a positive integer.

No need to consider this case separately.

Therefore, the total number of monotonous positive integers is 45 + 45 = 90.

In a haplodiploid system, the relatedness of a son to a maternal aunt is 75%.

In a haplodiploid system, males develop from unfertilized eggs and are haploid, while females develop from fertilized eggs and are diploid. This means that sons inherit all of their genetic material from their mother, including her alleles from both her haploid sets of chromosomes. Maternal aunts, on the other hand, share one set of haploid chromosomes with their nephew (the son), as they are the sister of his mother. Therefore, the relatedness between a son and his maternal aunt in a haplodiploid system is 0.75 or 75%.

In a haplodiploid system, the relatedness of a son to a maternal aunt can be calculated using the following steps:

1. Determine the relatedness of the son to his mother: In haplodiploid systems, sons are haploid and inherit their single set of chromosomes from their mother. This means that they are 100% related to their mother, as they share all her genes.

2. Determine the relatedness of the maternal aunt to the son's mother: The maternal aunt is a sister of the son's mother. In haplodiploid systems, sisters share 75% of their genes, as they get half of their genes from their mother and the other half from their father (who, as a haploid male, gives all his genes to his daughters).

3. Calculate the relatedness of the son to his maternal aunt: To determine the relatedness of the son to his maternal aunt, multiply the son's relatedness to his mother (100%) by the maternal aunt's relatedness to the son's mother (75%).

Relatedness of son to maternal aunt = (1.0) * (0.75) = 0.75 or 75%

So, in a haplodiploid system, the relatedness of a son to a maternal aunt is 75%.

To find the average rate of change of the function f(x) = 1.5x² over the interval [10, 11], we need to calculate the change in f(x) over the interval, and divide by the change in x.

The change in f(x) over the interval [10, 11] is:

f(11) - f(10) = (1.511^2) - (1.510^2) = 165 - 150 = 15

The change in x over the interval [10, 11] is:

Two angles are said to be supplementary angles because they combine to generate a linear angle when their sum is 180 degrees.

When two angles add up to 90 degrees, however, they are said to be complimentary angles and together they make a right angle.

If the total of two angles is 90o (ninety degrees), then the angles are complementary.

A 30-angle and a 60-angle, for instance, are two complementary angles.

So, to find the 2 angles which are complementary:

The tent with the assumed parameters is tall enough for the sisters to stand up inside.

Assuming a reasonable height for a typical tent, which is around 6 feet, it should be tall enough for both sisters to stand up inside if they are both over 5 feet tall.

In this case, we can imagine the tent as a triangular prism, with the sloping sides forming a right triangle.

Let's call the height of the tent "h," the length of the base "b," and the length of the sloping side "s."

Using the Pythagorean theorem, we can write:

s^2 = h^2 + (b/2)^2

Since we know that each sister is over 5 feet tall, we can set h = 5 feet. We also know that the base of the tent is usually wider than it is tall, so we can assume a reasonable value for b, such as 8 feet.

Substituting these values into the equation above, we get:

s^2 = 5^2 + (8/2)^2

s^2 = 25 + 16

s^2 = 41

Taking the square root of both sides, we get:

s ≈ 6.4 feet

Since this is greater than the height of both sisters (which is 5 feet), we can conclude that the tent is tall enough for them to stand up inside.

Answer:

m = 4

Y-intercept: 2

Step-by-step explanation:

8x + 4 = 2y

We rewrite the equation in slope-intercept form y = mx + b

m = the slope

b = y-intercept

8x + 4 = 2y

-2y + 8x + 4 = 0

-2y = -8x - 4

y = 4x + 2

m = 4

Y-intercept: 2

Rewriting the equation in slope-intercept form (y = mx + b) makes it easier to tell the slope and y-intercept. The rewritten form is y = 4x + 2. Since 'm' represents the slope, the slope of the equation is 4. 'b' represents the y-intercept, so the y-intercept is 2.

Answer:

Starting with the given equation:

Ob₁ = 2h/A - 2b₂

We want to solve for b₁. First, we can simplify the equation by multiplying both sides by 2:

2Ob₁ = 4h/A - 4b₂

Next, we can add 4b₂ to both sides to isolate the term involving b₁:

2Ob₁ + 4b₂ = 4h/A

Then, we can multiply both sides by A/4h to solve for b₁:

b₁ = (2Ob₁ + 4b₂) * A/4h

Simplifying this expression, we get:

b₁ = (O/h + 2b₂) * A/2

Therefore, the solution for b₁ is:

b₁ = (O/h + 2b₂) * A/2

or

b₁ = (A O + 2b₂h)/2h

In the equation A=bh, b can be solved as b=A/h. For the equation h(b₁ + b₂)=2, b₁ can be solved as b₁=2/h-b₂

To solve the equation A = bh for b, we can isolate b by dividing both sides of the equation by h. Thus, b = A/h. For the equation h(b₁ + b₂) = 2, we isolate b₁ by first dividing both sides by h to get (b₁ + b₂) = 2/h. Then, we can subtract b₂ from both sides to solve for b₁, yielding b₁ = 2/h - b₂.
