We need to convert both quantities to the same units before we can compare them.

24 ounces is equal to 1.5 pounds (since there are 16 ounces in 1 pound).

So the ratio of 24 ounces to 12 pounds can be written as:

1.5 pounds : 12 pounds

Simplifying this ratio by dividing both sides by 12, we get:

0.125 : 1

Therefore, the ratio that compares the relative sizes of 24 ounces to 12 pounds is 0.125 : 1.

To rewrite the quadratic function y = -9(x-1)²-6 in standard form, we need to expand the squared term and simplify the expression. Here are the steps:

Distribute the negative sign to the squared term: y = -9(x² - 2x + 1) - 6

Multiply -9 by each term inside the parentheses: y = -9x² + 18x - 9 - 6

Combine the constants: y = -9x² + 18x - 15

Therefore, the standard form of the quadratic function y = -9(x-1)²-6 is y = -9x² + 18x - 15.

Answer:

I'm assuming that 1 is actually a point with coordinates (1, something) and you meant the point H(25,-16).

To find the equation of the line passing through two points (x1,y1) and (x2,y2), we can use the point-slope form:

y - y1 = m(x - x1)

where m is the slope of the line, which can be calculated as:

m = (y2 - y1) / (x2 - x1)

Using the points H(25, -16) and 1(-2.5, y), we have:

m = (-16 - y) / (25 - (-2.5)) = (-16 - y) / 27.5

Multiplying both sides by 27.5, we get:

-16 - y = -0.58x + b

where x is the x-coordinate and b is the y-intercept of the line. To find b, we plug in one of the points (let's use H) and solve for b:

-16 - (-16) = -0.58(25) + b

b = -16 - (-14.5) = -1.5

Therefore, the equation of the line passing through H(25, -16) and 1(-2.5, y) is:

y + 1.5 = -0.58(x + 2.5)

or:

y = -0.58x - 4.25

Note: I assumed that you meant H(25,-16) and I used -2.5 as the x-coordinate for point 1 because you didn't specify what it was.

The total cost is the same for both locations when there are 10 guests.

To determine the number of guests for which the total cost is the same at each location, we need to set up an equation and solve for the number of guests (let's call it x).

Roller rink cost: 5x + 55

Laser tag cost: 8x + 25

Now, set the two costs equal to each other and solve for x:

5x + 55 = 8x + 25

Subtract 5x from both sides:

55 = 3x + 25

Subtract 25 from both sides:

30 = 3x

Divide by 3:

x = 10

So, the total cost is the same for both locations when there are 10 guests.

The value of P and Q is 35.

Let's first understand the given information:

Charles has two six-sided dice, one fair and one biased. The fair die has equal probabilities for each side (1/6). The biased die has a 2/3 probability for rolling a six and 1/15 probability for each of the other five sides. Charles chooses a die randomly and rolls it three times.

Given that the first two rolls are sixes, we are asked to find the probability that the third roll will also be a six, expressed as a simplified fraction p/q.

We can solve this problem using conditional probability. Let A be the event that Charles chooses the biased die, and B be the event that he rolls three sixes in a row. We want to find the probability of B given A.

P(B|A) = P(A ∩ B) / P(A)

Since Charles chooses the die randomly, P(A) = 1/2. To find P(A ∩ B), we need to find the probability that Charles chooses the biased die and rolls three sixes in a row. This can be calculated as:

P(A ∩ B) = P(A) * P(rolling three sixes with the biased die) = (1/2) * (2/3)^3

Now we can find P(B|A):

P(B|A) = P(A ∩ B) / P(A) = ((1/2) * (2/3)^3) / (1/2) = (2/3)^3 = 8/27

Thus, the probability that the third roll will also be a six, given that the first two rolls are sixes, is 8/27, so the answer is p + q = 8 + 27 = 35.

Jamie will therefore need five days to complete the book as a result, P – 90 pages equals 3/8 of the book.

A mathematical strategy for resolving proportionality issues is the unitary method. Finding the price of one unit is the first step, and utilizing that value to determine the value of yet another quantity with a different quantity is the second. Consider being told, for instance, that an automobile drives 300 kilometres in 5 hours. You are able to employ the unitary technique as shown below to determine how far the car drives in eight hours. For example, 1 hour is equal to 300/5, or 60 miles. To calculate the value of eight hours, use this value: Since 8 hours are equal to 8/1 units, 480 miles are covered in 8 hours.

given

Let P represent the book's total number of pages.

Jessica reads 30 pages per day, which translates to 330 pages after 3 days, or 90 pages total.

5/8 of the book is still to be read, which indicates that 3/8 of it has already been. As a result, P – 90 pages equals 3/8 of the book.

Divide both sides by 5, and you get:

P = 144

The book thus has 144 pages.

Regarding the second query:

She reads 45 pages per 225 pages, or 1/5 of the book.

We divide the total number of pages by the average number of pages Jamie reads each day to determine the number of days Jamie will need to finish the book.

Answer: 185.64 inches

The surface area of the box is 185.64 square inches.

The area is the amount of area occupied by an object's flat (2-D) surface or shape.

To find the surface area of the box, we need to calculate the area of each face and then add them up.

The four faces are rectangles with dimensions 8.8 inches by 4.3 inches, so their area is 4(8.8)(4.3) = 151.36 square inches.

The other area can be described as 2(4.3)(4.3) =36.98 square inches.

Finally, we need to account for the rectangular tear on one of the sides, which has dimensions of 0.5 inches by 5.4 inches. This tear creates an additional face with area (0.5)(5.4) = 2.7 square inches.

Therefore, the total surface area of the tissue box is:

151.36 + 36.98 - 2.7 =  185.64 square inches.

Hence, the surface area of the box is 185.64 square inches.

The correct equation would be:

0b. A = 240 - 4h

Explanation:

If Clayton can plow 4 acres per hour, the number of acres he can plow in 'h' hours would be 4h.

Therefore, the number of acres left to plow would be the total number of acres (240) minus the number of acres he has already plowed (4h).

Hence, the equation that represents the number of acres left to plow would be A = 240 - 4h.

Based on the given information, the angle is C. 22.1° an  A. 20.4°.

Trigonometric functions are mathematical functions that relate the angles and sides of a right triangle.

The basic trigonometric functions are:

Sine (sin): the ratio of the length of the side opposite an angle to the length of the hypotenuse of the triangle.

Cosine (cos): the ratio of the length of the side adjacent to an angle to the length of the hypotenuse of the triangle.

Tangent (tan): the ratio of the length of the side opposite an angle to the length of the side adjacent to the angle.

We can use the trigonometric function tangent to find angle R in the right triangle:

tan(R) = opposite/adjacent = PQ/QR

tan(R) = 5.2/13.4

R = tan⁻¹(5.2/13.4)

R ≈ 22.1°

Therefore, the answer is C. 22.1° rounded to one decimal place.

Using the Pythagorean theorem, we can find the length of side AB:

AB = √(AC² - BC²)

= √(25² - 10²)

= √(575)

Now we can use the sine function to find the measure of angle C:

sin(C) = BC/AB

C = sin⁻¹(BC/AB)

= sin⁻¹(10/√(575))

≈ 20.4°

Therefore, the answer is A) 20.4°.
