Let's start by assigning variables to the unknown quantities in the problem. Let h be the height of the triangle in inches, and let b be the base of the triangle in inches.

According to the problem, the base of the triangle is 3 inches shorter than its height. This can be expressed as:

b = h - 3

The formula for the area of a triangle is:

A = (1/2)bh

We are given that the area of the triangle is 275 square inches, so we can substitute these values into the formula to get:

275 = (1/2)(h)(h-3)

Simplifying the right-hand side, we get:

275 = (1/2)(h^2 - 3h)

Multiplying both sides by 2 to eliminate the fraction, we get:

550 = h^2 - 3h

Rearranging this equation to standard quadratic form, we get:

h^2 - 3h - 550 = 0

Now we can solve for h using the quadratic formula:

h = (-b ± sqrt(b^2 - 4ac)) / (2a)

In this case, a = 1, b = -3, and c = -550, so we can substitute these values into the formula to get:

h = (-(-3) ± sqrt((-3)^2 - 4(1)(-550))) / (2(1))

Simplifying the expression inside the square root, we get:

h = (3 ± sqrt(2209)) / 2

We can ignore the negative solution since height must be positive, so we get:

h = (3 + sqrt(2209)) / 2 ≈ 29.04

Now that we know the height of the triangle is approximately 29.04 inches, we can use the equation b = h - 3 to find the length of the base:

b = 29.04 - 3 = 26.04

Therefore, the base of the triangle is approximately 26.04 inches, and the height is approximately 29.04 inches.

Answer: The poster should have width 17.50 CM

Step-by-step explanation:

Given that boasted I have a total area 245 cm square area of a poster is 200 and 45 20 m square. And it is in the rectangle format. So we know that the poster is always in the rectangle format and the area of rectangular area is equal to L N T W. So 245 will be equal to Ln tW. From this. We need to find L. So L is equal to 245 divided by W. Now consider the diplomatic representation of the poster. So it has mentioned that there is a margin around the edges of six cm at the top. This is 6cm and four cm at the sites. All the four sides 3 sides are four cm. So from this we need to find land and the doctor posted area that is printed area. The first wine printed with www. Z. Quilter. Now let this be total birth will be W. And this will be four and this will be four. Therefore posted with will be we need to find this part alone. So W -4 -4 will give the this part with. So W -4 -4. So post printed with PW will be equal to W -8. Similarly printed lunch will be equal to The total length is already we have found 245 by W. And we need to find this part length. So we have to subtract six and four from the total length so that that will give them this part length, So -6 -4. So printed length will be equal there 245 Divided by W -10. And we know that formula for area of a rectangle. Urz D is equal to L W. Now substitute the printed with and printed length in the area formula. We have to find the printed area. So Printed area Zeke Walter W -8 into 245 Divided by W -10. To simplify this, we get 325 minus 10. W -100 and 30,960 W. to the power of -1. Now fine D A by D. T. Not D D. This is D. W. So this is equal to differentiation of constant alma zero, this is minus 10 plus 900 and 60 W. to the power of -2 and equate this to be equal to zero. We out to find the maximum width so D A by D W is equal to zero, therefore minus 10 1960 W. To the power of -2 will be equal to zero. To simplify this, we get them maximum with value the W is equal term I wrote off 196. Therefore the value of W. Z quilter plus or minus 14. We will neglect the negative values since we cannot be negative. So one we assume the positive values. So what will be equal to 14 and length will be equal to 245 divided by 14, So which will be equal to 17.50 centimeters. And they have concluded that At W is equal to 14 cm and lunch will be equal to 17.50 cm needed to print the largest area. I hope you found the answer to school. Thank you.

Answer:

888.4 mL.

Step-by-step explanation:

To solve this problem, we can use the following formula:

Amount of drug (in mg) = concentration (in mg/mL) × volume (in mL)

We are given the concentration of the drug as 5.315 mg per 3.743 mL. To find the volume of the drug needed to give 4.719 g, we need to rearrange the formula to solve for volume:

Volume (in mL) = amount of drug (in mg) ÷ concentration (in mg/mL)

First, we need to convert 4.719 g to mg by multiplying by 1000:

4.719 g × 1000 mg/g = 4719 mg

Now we can substitute the given concentration and the calculated amount of drug into the formula and solve for volume:

Volume (in mL) = 4719 mg ÷ 5.315 mg/mL

Volume (in mL) ≈ 888.5 mL

Therefore, approximately 888.5 mL of the drug are needed to give 4.719 g. Rounded to 1 decimal, the answer is 888.4 mL.

The value of angle that maximizes the cross sectional area is 60°

The cross sectional area of a solid is the two dimensional surface formed when the solid is sectioned by a plane.

The shape of the cross sectional area of the gutter is a trapezoid

Area of a trapezoid = ((Sum of the lengths of the parallel sides)/2) × Height

Let a and b represent the parallel sides of the trapezoid, and let a represent the base of the trapezoid we get;

A = ((a + b)/2) × h

a = 3 inches

b = The longer parallel side

h = The height of the trapezoid

The angle formed by the sides of a trapezium and the horizontal = θ

Therefore;

h = 3 × sin(θ)

b = 3 + 2 × 3·cos(θ)

A(θ) = ((3 + 3 + 2 × 3·cos(θ)) × 3 × sin(θ))/2 = 9·sin(θ)·cos(θ) + 9·sin(θ)

At the extremum value of θ, we get;

A'(θ) = 18·cos²(θ) + 9·cos(θ) - 9 = 0

Solving, we get;

cos(θ) = 0.5 or cos(θ) = -1

Therefore;

θ = arccos(0.5) = 60° and θ = arccos(0.5) = 180°

When θ = 60°, we get;

A(max) = 9·sin(60)·cos(60) + 9·sin(60) ≈ 11.69

The cross sectional area when θ is 60° is about 11.69 square inches which is larger than the 9 square inched when θ = 90°

The angle that maximizes the cross sectional area is θ = 60°

Answer:

K

Step-by-step explanation:

We can factor the given expression as:

p(p + 1)(p - 1) = p^3 - p

Notice that p^3 - p is the difference of two consecutive cubes. This can be factored further using the identity a^3 - b^3 = (a - b)(a^2 + ab + b^2):

p^3 - p = p(p^2 - 1) = p(p + 1)(p - 1)

So, we have shown that p(p + 1)(p - 1) is equal to p^3 - p, which is the product of three consecutive integers. By definition, this product is always divisible by 3.

However, we cannot conclude that p(p + 1)(p - 1) is divisible by 4, 5, or 7 for all positive integers p. Therefore, the answer is K) None of these.

Answer:

Step-by-step explanation:

Let B be the event that the selected coin is biased, and F be the event that the selected coin is fair. Let H be the event that the coin toss shows a head.

We want to find P(B|H), the probability that the selected coin is biased given that the coin toss shows a head. By Bayes' theorem, we have:

P(B|H) = P(H|B) * P(B) / P(H)

We know that P(H|B) = 1/4 (since the biased coin has a probability of 1/4 of showing a head), and that P(B) = 1/2 (since there are two coins, one of which is biased).

To find P(H), we can use the law of total probability:

P(H) = P(H|B) * P(B) + P(H|F) * P(F)

P(H) = (1/4) * (1/2) + (1/2) * (1/2)

P(H) = 3/8

Putting it all together:

P(B|H) = P(H|B) * P(B) / P(H)

P(B|H) = (1/4) * (1/2) / (3/8)

P(B|H) = 1/3

Therefore, the probability that the selected coin is biased given that the coin toss shows a head is 1/3.

Answer: p = 1.5 and q = 9

Step-by-step explanation:

Expand the right side then compare the coefficients of like terms on both sides, that is

4(x + p)² - q ← expand (x + p)² using FOIL

= 4(x² + 2px + p²) - q ← distribute parenthesis

= 4x² + 8px + 4p² - q

Comparing coefficients of like terms on both sides

8p = 12 ( coefficients of x- terms ) ← divide both sides by 8

p = 1.5

4p² - q = 0 ( constant terms ), that is

4(1.5)² - q = 0

9 - q = 0 ( subtract 9 from both sides )

- q = - 9 ( multiply both sides by - 1 )

q = 9

The result of the cross breeding between the heterozygous and homozygous pea plant is  the offspring will have a 50% chance of inheriting the dominant "G" allele and displaying yellow color, and a 50% chance of inheriting the recessive "g" allele and displaying green color.

In this problem, the heterozygous pea plant with yellow color is represented as "Gg" (where "G" is the dominant allele for yellow color and "g" is the recessive allele for green color). The homozygous pea plant with green color is represented as "gg" (where both alleles are recessive).

When these two plants are crossed, their offspring will inherit one allele from each parent, which will determine their phenotype (observable trait).

The possible combinations of alleles that the offspring can inherit from their parents are:

The probability of waiting at least 26 minutes is 0.316. The average waiting time is 19 minutes.

Step 1:

The probability of waiting at least 26 minutes can be calculated by finding the area under the probability density function from 26 to 38:

P(waiting at least 26 minutes) = ∫26^38 (1/38) dt = [t/38] from 26 to 38

= (38/38) - (26/38) = 12/38 = 0.316

So the probability of waiting at least 26 minutes is 0.316 or approximately 0.316 rounded to 3 decimal places.

Step 2:

The average waiting time can be calculated by finding the expected value of the probability density function:

E(waiting time) = ∫0³⁸ t f(t) dt = ∫0³⁸ (t/38) dt

= [(t²)/(238)] from 0 to 38

In the context of a semi-circle, the perimeter refers to the total distance around the curved edge of the semi-circle. It is calculated by adding the length of the straight edge (diameter) to half the circumference of the semi-circle.

The total area of the floor of the swimming pool is 23.86 square meters.

The diameter of the semi-circle is twice the radius, so the diameter is 2 × 5.5m = 11m.

Therefore, the perimeter of the semi-circle is:

Perimeter = Diameter + Circumference/2

Perimeter = 11m + 17.3m/2

Perimeter = 20.3m

The length of the swimming pool is equal to the perimeter of the semi-circle, which is 20.3 meters.

To calculate the total area of the floor of the swimming pool, we need to find the area of the semi-circle. The formula for the area of a semi-circle is:

Area = πr²/2

where π is a constant approximately equal to 3.14 and r is the radius of the semi-circle.

In this case, the radius is 5.5m, so the area of the semi-circle is:

Area = π(5.5m)²/2

Area = 47.71m²/2

Area = 23.86m²

Therefore, the total area of the floor of the swimming pool is 23.86 square meters.
