the other two angles of the triangle must also be equal, which means that the other two sides of the triangle must be equal as well. the length of the shorter sides is [tex]y = 16 feet[/tex] .

Let's start by using the information given to write equations for the perimeter of the heptagon in terms of the length of the sides:

Let x be the length of the four equal sides, and y be the length of the remaining three sides, which are half as long. Then, we have:

Perimeter  [tex]= 4x + 3y[/tex]

We also know that the perimeter is 88 feet, so we can set up the equation:

[tex]4x + 3y = 88[/tex]

Now we need to solve for y, which represents the length of the shorter sides.

We can simplify the equation by substituting y = (1/2)x:

[tex]4x + 3(1/2)x = 88[/tex]

Simplifying this expression, we get:

[tex]7x/2 = 88[/tex]

Multiplying both sides by 2/7, we get:

[tex]x = 32[/tex]

Now that we know x, we can find y by substituting it into the equation y   [tex]= (1/2)x[/tex]:

[tex]y = (1/2)(32) = 16[/tex]

Therefore, the length of the shorter sides is  [tex]y = 16[/tex] feet.

Answer / Step-by-step explanation:

To represent the solutions of the linear inequality y < 2x + 5 on a graph, we can follow these steps:

First, we draw the boundary line y = 2x + 5, which is a straight line with a slope of 2 and a y-intercept of 5.

Since the inequality is y < 2x + 5, we need to shade the region that is below the boundary line. This is because any point below the line will have a y-coordinate that is less than 2x + 5, which satisfies the inequality.

We can also use a dashed line to represent the boundary line, since the inequality is strict (y < 2x + 5, not y ≤ 2x + 5).

Finally, we can check the solutions to the inequality by picking any point in the shaded region and plugging its coordinates into the inequality. If the resulting statement is true, then that point is a valid solution to the inequality. If the statement is false, then the point is not a solution.

Therefore, to represent the solutions of the inequality y < 2x + 5 on a graph, we would shade below the dashed line y = 2x + 5.

Isosceles triangle is the shape which has exactly one line of symmetry.

The surface area of the pyramid is 74.25 square meters.

Surface area is the total area that the surface of an object occupies. It is the sum of the areas of all the faces, sides, and curved surfaces of an object. Surface area is usually measured in square units, such as square meters, square feet, or square centimeters.

A pyramid is a polyhedron with a polygonal base and triangular faces that meet at a common vertex (known as the apex). Pyramids are named according to the shape of their base.

In the given question,

The area of the base is simply the area of a square, which is:

Area of base = length x width = 4.5m x 4.5m = 20.25 square meters

To find the area of each triangular face, we first need to find the length of the slant height (the height of the triangle).

We can use the Pythagorean theorem to do this:

h²= (1/2 x base)² + height²

h² = (1/2 x 4.5)² + 6²

h² = 2.25 + 36

h² = 38.25

h = √38.25

h = 6.18 meters (rounded to two decimal places)

Now that we know the slant height, we can find the area of each triangular face:

Area of one triangular face = (1/2 x base x height) = (1/2 x 4.5 x 6) = 13.5 square meters

Since there are four triangular faces on a square pyramid, we need to multiply this by 4 to find the total area of the triangular faces:

Total area of triangular faces = 4 x 13.5 = 54 square meters

Finally, we can find the surface area of the pyramid by adding the area of the base and the area of the triangular faces:

Surface area = Area of base + Total area of triangular faces

Surface area = 20.25 + 54

Surface area = 74.25 square meters

Therefore, the surface area of the pyramid is 74.25 square meters.

232 child's plates were served and 103 adult's plates were served after rounding to the nearest whole number.

The substitution method involves solving one equation for one variable in terms of the other variable, and then substituting this expression into the other equation.

Let's use the following variables:

c = number of child's plates served

a = number of adult's plates served

We can set up a system of two equations based on the given information:

c + a = 335 (the total number of plates served was 335)

2.6c + 8.3a = 1458.1 (the total amount collected was $1458.10)

To solve this system, we can use the substitution method. Rearrange the first equation to solve for one variable in terms of the other:

c = 335 - a

Substitute this expression for c in the second equation and solve for a:

2.6(335 - a) + 8.3a = 1458.1

871 - 2.6a + 8.3a = 1458.1

5.7a = 587.1

a = 103

Now that we know there were 103 adult's plates served, we can substitute this value back into the first equation and solve for c:

c + 103 = 335

c = 232

Therefore, 232 child's plates were served and 103 adult's plates were served.

Answer:

Step-by-step explanation:

I'm sorry, but there seems to be some information missing from your question. Specifically, it is unclear what quantity or angle you want to determine the cosine of.

If you meant to ask for the value of the cosine of an angle given that its sine is 3/4, then we can use the Pythagorean identity to determine the cosine:

sin^2(x) + cos^2(x) = 1

Plugging in sin(x) = 3/4, we get:

(3/4)^2 + cos^2(x) = 1

Simplifying, we have:

9/16 + cos^2(x) = 1

Subtracting 9/16 from both sides, we get:

cos^2(x) = 7/16

Taking the square root of both sides, we get:

cos(x) = ±sqrt(7)/4

Since the sine is positive (3/4 is in the first quadrant), we know that the cosine must also be positive. Therefore:

cos(x) = sqrt(7)/4

The graph represents a proportional relationship.

What is proportional relationship?

A proportional relationship is a relationship between two variables where their ratio remains constant. This means that as one variable increases or decreases, the other variable changes proportionally in order to maintain a constant ratio. In other words, the two variables are directly proportional to each other. This relationship can be represented by a straight line passing through the origin on a graph. Proportional relationships are commonly used in various fields such as physics, finance, and engineering to analyze and predict outcomes.

Explaining the table, equation and graph to know which represents a proportional relationship :

The relationship between the values in the given table is not proportional. If it was a proportional relationship, then the ratio of y to x would be constant. However, in this case, the ratios are not equal. For example, the ratio of y to x for the first row is 3.6/3 = 1.2, but the ratio of y to x for the second row is 6/5 = 1.2, and the ratio of y to x for the third row is 7.2/8 = 0.9. Therefore, the ratios are not equal and the relationship is not proportional.

The equation y=2x+5 does not represent a proportional relationship. In a proportional relationship, there is a constant ratio between the two variables. However, in this equation, the ratio between y and x is not constant, but rather it increases as x increases.

3/4 of 48 is 36

Answer:

(a) 22 inches

(b) 770 inches

(c) 26,950 inches

Step-by-step explanation:

(a) To find the perimeter of the drawing, we add up the lengths of all four sides:

Perimeter of drawing = 7 + 4 + 7 + 4 = 22 inches

(b) The length and width of the actual garden are 35 times larger than the dimensions in the drawing. This means that the actual length is 7 x 35 = 245 inches and the actual width is 4 x 35 = 140 inches. To find the perimeter of the actual garden, we add up the lengths of all four sides:

Perimeter of actual garden = 245 + 140 + 245 + 140 = 770 inches

(c) When the dimensions of the garden are multiplied by 35, the perimeter of the garden will also be multiplied by 35. This is because each side will increase by a factor of 35, so the total length of all four sides will increase by a factor of 35 as well. Therefore, the new perimeter will be:

New perimeter = 35 x Perimeter of actual garden = 35 x 770 = 26,950 inches

Numbers between 100 and 200 which are also equal to a square number multiplied by a prime number are:

Step-by-step explanation:

A square number is a number that has been multiplied by itself.

For example, 25 is a square number as 5 × 5 = 25.

The square numbers between zero and 200 are:

A prime number is a whole number greater than 1 that cannot be made by multiplying other whole numbers (its only factors are 1 and itself).

Since the smallest square number is 4, and our final number needs to be between 100 and 200, we only need to list the primes numbers that are less than 50 as 4 × 50 = 200.

Begin with the smallest prime number, 2. If we divide 100 and 200 by this prime number, we get 50 and 100. Therefore, to find a number between 100 and 200 that is equal to a square number multiplied by a prime number, the square number should be more than 50 and less than 100.  Therefore:

The next smallest prime number is 3. If we divide 100 and 200 by 3 we get 33.33.. and 66.66...  Therefore, the prime number 3 should be multiplied by a square number that is more than 33 and less than 67:

The next prime number is 5. If we divide 100 and 200 by 5 we get 20 and 40.  Therefore, the prime number 5 should be multiplied by a square number that is more than 20 and less than 40:

Continuing this way, all the numbers that are between 100 and 200, which are also equal to a square number multiplied by a prime number are:

Number between 100 and 200 which is also equal to a square number multiplied by a prime number is 147.

A prime number is a positive integer greater than 1 that has no positive integer divisors other than 1 and itself. In simpler terms, a prime number is a number that can only be evenly divided by 1 and itself.

To find this number, I first looked for square numbers between 100 and 200. The square numbers within this range are 121 (11 squared) and 169 (13 squared).

I then checked if either of these square numbers could be multiplied by a prime number to equal a number between 100 and 200. After some calculation, I found that 169 cannot be multiplied by a prime number to give a number between 100 and 200. However, 121 can be multiplied by 2 to give 242, which is greater than 200.

Finally, I checked if there were any other square numbers I missed. I found that 7 squared is equal to 49, which when multiplied by 3 (a prime number) gives 147, a number between 100 and 200 that satisfies the problem.

Therefore, the number between 100 and 200 which is also equal to a square number multiplied by a prime number is 147.

After answering the presented question, we can conclude that function Therefore, the maximum growth rate of  [tex]f(t)[/tex] occurs at  [tex]t = k ln(Λ)[/tex] .

In mathematics, a function appears to be a link between two sets of numbers, in which each member of the first set (known as the domain) corresponds to a specific member of the second set (called the range).

A formula or a graph can be used to represent a function. For example, the formula  [tex]y = 2x + 1[/tex] depicts a functional form in which each value of x generates a unique value of y.

To find the maximum growth rate of  [tex]f(t)[/tex] between t=0 and t=kA, we need to find the maximum value of its derivative with respect to t. Let's start by taking the derivative of f(t) using the chain rule:

[tex]f'(t) = -kΛe^(-kt) / B(1 + Λe^(-kt))^2[/tex]

Now we need to find the value of t that maximizes f'(t). One way to do this is to use logarithmic differentiation. First, take the natural logarithm of both sides of the equation for f'(t):

Next, take the derivative of both sides with respect to t:

[tex]f''(t)/f'(t) = -k + Λke^(-kt) / (1 + Λe^(-kt))[/tex]

Simplifying this expression by multiplying both numerator and denominator by [tex]e^(kt)[/tex], we get:

[tex]f''(t)/f'(t) = -k + Λk / (e^(kt) + Λ)[/tex]

Now we can set f''(t)/f'(t) equal to zero to find the critical points:

[tex]-k + Λk / (e^(kt) + Λ) = 0[/tex]

Multiplying both sides by [tex]e^(kt)[/tex] + Λ and rearranging, we get:

[tex]e^(kt) = Λ/k[/tex]

Taking the natural logarithm of both sides, we get:

[tex]kt = ln(Λ) - ln(k)[/tex]

Solving for t, we get:

[tex]t = ln(Λ)/k - ln(k)/k[/tex]

[tex]t = (ln(Λ) - ln(k))/k[/tex]

[tex]t = ln(Λ/k)/k[/tex]

Substituting this value of t back into f'(t), we get:

[tex]f'(ln(Λ/k)/k) = -kΛe^(-ln(Λ)) / B(1 + Λe^(-ln(Λ)))^2[/tex]

Since A>1, we know that Λ>1. Therefore, e^(-ln(Λ)) = 1/Λ, and we can simplify the expression for f'(ln(Λ/k)/k) to:

[tex]f'(ln(Λ/k)/k) = -k/ΛB(1 + 1/Λ)^2[/tex]

We can now see that f'(ln(Λ/k)/k) is negative, which means that f(t) is decreasing at that point. Therefore, the maximum growth rate of f(t) must occur at either t=0 or t=kA. We can find which one of these is the maximum by comparing the values of f'(0) and f'(kA).

[tex]f'(0) = -kΛ/B(1 + Λ)^2[/tex]

[tex]f'(kA) = -kΛe^(-kA) / B(1 + Λe^(-kA))^2[/tex]

We know that A>1, which means that kA>k. Therefore,  [tex]e^(-kA) < e^(-k),[/tex]  which means that f'(kA) is greater in magnitude than f'(0). Since f'(kA) is negative, this means that f(t) is decreasing faster at t=kA than at   [tex]t=0.[/tex]

Therefore, the maximum growth rate of  [tex]f(t)[/tex]occurs at [tex]t=ln(Λ)/k[/tex]  , as given by the formula we derived earlier.

It takes the hiker about 175.58 minutes to climb the remaining elevation of the mountain in stage two.

calculating the elevation the hiker climbs in stage one:

2% of 2,150 feet = 0.02 × 2,150 feet = 43 feet

Therefore, the hiker climbs 43 feet in stage one. To find the time it takes for the hiker to climb the remaining elevation of the mountain in stage two, we need to know the total elevation he needs to climb in this stage. This can be calculated by subtracting the elevation climbed in stage one from the total elevation of the mountain: Total elevation - Elevation climbed in stage one = 2,150 - 43 = 2,107 feet

Now, we can use the rate of climb in stage two to find the time it takes to climb 2,107 feet:

Time = Distance / Rate

Time = 2,107 feet / 12 feet per minute

Time ≈  175.58 minutes

Therefore, it takes the hiker about 175.58 minutes to climb the remaining elevation of the mountain in stage two.

Plugging in the values, we get:

Variance = 25 × 0.6 × (1 - 0.6)

Variance = 25 × 0.6 × 0.4

Variance = 6

The binomial distribution is a probability distribution that models the number of successes in a fixed number of independent trials, where each trial has only two possible outcomes, success or failure. In this case, the trials are the 25 citizens who were chosen, and the success is the event of favoring the supermarket, which has a probability of 0.6.
