Answer:
Let's start by defining some variables to represent the given information:
T0 = 48°F (the current temperature)
deltaT = -1.5°F/hour (the rate of change in temperature)
T = 36°F (the target temperature)
We want to find how many hours it will take for the temperature to drop from 48°F to 36°F, so let's call that time h. We can use the formula for the linear relationship between temperature and time:
T = T0 + deltaT * h
We want to solve for h when T = 36°F, so we can substitute the given values and solve for h:
36 = 48 + (-1.5) * h
-12 = -1.5h
h = 8
Therefore, it will take 8 hours for the temperature to drop from 48°F to 36°F, assuming the temperature continues to decrease at a rate of 1.5°F per hour.

What are an equation and an expression?A mathematical expression shows the worth of something by combining numbers, factors, and functions. A mathematical assertion known as an equation involves setting two expressions equivalent to one another.
We can start by using the identity:
cos 2x = cos² x - sin² x
We can rearrange this to get:
cos² x = cos 2x + sin² x
Substituting this into the expression we want to simplify, we get:
(cos² x - sin² x - 1) / (sin 2x)
We can then use the identity:
sin 2x = 2 sin x cos x
Substituting this into the expression, we get:
(cos² x - sin² x - 1) / (2 sin x cos x)
We can simplify the numerator using the identity:
cos² x - sin² x = cos 2x
Substituting this into the expression, we get:
(cos 2x - 1) / (2 sin x cos x)
Therefore, the simplified expression is:
(cos 2x - 1) / (2 sin x cos x)

The value of x is equal to 10.
What is the basic proportionality theorem?In Mathematics, the basic proportionality theorem states that when any of the two (2) sides of a line segment is intersected by a straight line which is parallel to the third (3rd) side of the line segment, then, the two (2) sides that are intersected would be divided proportionally and in the same ratio.
By applying the basic proportionality theorem to the given triangle, we have the following:
21/(x - 3) = 27/(x - 1)
By cross-multiplying, we have the following:
21(x - 1) = 27(x - 3)
21x - 21 = 27x - 81

Subtract the ratiunal expressi answer in its fully factored for (m^(2)+4m-12)/(m^(2)-64)-(m^(2)+11m+24)/(2m^(2)-128)
The fully factored form is (m-9)(m-12)(m+2) / [2(m+8)(m-8)].
To subtract the rational expressions and find the answer in its fully factored form, we first need to find a common denominator for the two expressions.
The denominators of the two expressions are (m^(2)-64) and (2m^(2)-128). We can factor both of these to find the common denominator.
(m^(2)-64) = (m+8)(m-8)
(2m^(2)-128) = 2(m^(2)-64) = 2(m+8)(m-8)
The common denominator is 2(m+8)(m-8).
Now we can rewrite the two expressions with the common denominator and subtract them:
[(m^(2)+4m-12)(2) - (m^(2)+11m+24)(m+8)(m-8)] / [2(m+8)(m-8)]
= [(2m^(2)+8m-24) - (m^(3)+11m^(2)+24m+8m^(2)+88m+192)] / [2(m+8)(m-8)]
= [m^(3)-17m^(2)-104m-216] / [2(m+8)(m-8)]
= (m-9)(m^(2)-8m-24) / [2(m+8)(m-8)]
= (m-9)(m-12)(m+2) / [2(m+8)(m-8)]
So the answer in its fully factored form is (m-9)(m-12)(m+2) / [2(m+8)(m-8)].

Rewrite the quadratic function in standard form. f (x) = x2 - 8x + 23 Get Hint Enter Your Step Here 7 4
The quadratic function in standard form of f (x) = x2 - 8x + 23 is (x) = (x - 4)2 + 7.
The quadratic function given is f (x) = x2 - 8x + 23. To rewrite this function in standard form, we need to complete the square for the x terms. Standard form for a quadratic function is f (x) = a(x - h)2 + k, where (h, k) is the vertex of the parabola.
f (x) = 1(x2 - 8x) + 23
Step 2: Take half of the coefficient of the x term, square it, and add it inside the parentheses. In this case, half of -8 is -4, and -4 squared is 16.f (x) = 1(x2 - 8x + 16) + 23 - 16
Step 3: Simplify the constant term outside of the parentheses.f (x) = 1(x2 - 8x + 16) + 7
Step 4: Factor the quadratic inside the parentheses.f (x) = 1(x - 4)2 + 7
Step 5: Simplify the coefficient of the quadratic term, if necessary. In this case, the coefficient is 1, so there is no need to simplify further.The final answer is f (x) = (x - 4)2 + 7, which is the standard form of the given quadratic function.

The volume of the right square pyramid with the dimensions e = 5m, h = 4m, and s = 6m is 48m³.
What is pyramid?Pyramid is a structure with a polygonal base and triangular sides that meet at a point. Pyramids have been used throughout history as tombs, temples and monuments. Many of the most famous pyramids are located in Egypt, such as the Great Pyramid of Giza.
The volume of a right square pyramid is equal to one-third of the base area multiplied by the height. To find the volume of this pyramid, we first need to calculate the base area.
The base area of a square pyramid is equal to the length of one side (s) squared. Since the length of one side of this pyramid is 6m, the base area is 6m x 6m, which equals 36m².
Now that we know the base area, we can calculate the volume of the pyramid. The volume is equal to one-third of the base area multiplied by the height. In this case, the volume of the pyramid is one-third of 36m² multiplied by 4m, which equals 48m³.
Therefore, the volume of the right square pyramid with the dimensions e = 5m, h = 4m, and s = 6m is 48m³.

To add or subtract polynomials, we need to combine like terms. Like terms are terms that have the same variable and the same exponent.
First, let's add the first two polynomials:
((2)/(5)a^(4)-6a^(3)-(5)/(6)a^(2)+(a)/(2)+1)+((9)/(4)a^(3)+(2a^(2))/(3)+(5)/(3)a-(8)/(5))
= (2/5)a^(4) + (-6 + 9/4)a^(3) + (-5/6 + 2/3)a^(2) + (1/2 + 5/3)a + 1 - 8/5
= (2/5)a^(4) + (-15/4)a^(3) + (1/6)a^(2) + (11/6)a - 3/5
Now, let's subtract the third polynomial from this result:
(2/5)a^(4) + (-15/4)a^(3) + (1/6)a^(2) + (11/6)a - 3/5 - (2a^(2)b^(2)+3ab^(2)-5a^(2)b)

Finally, let's subtract the last term from this result:
(2/5)a^(4) + (-15/4)a^(3) + (1/6)a^(2) + (11/6)a - 3/5 - 2a^(2)b^(2) - 3ab^(2) + 5a^(2)b - (3a^(2)b^(2)-9)

Solving a quadratic equation we can see that Jason will hit the water after 6 seconds.
After how many seconds, did Jason hit the water?We know that the height of Jason is modeled by the quadratic function:
h = - 16x² + 16x + 480
The water is at h = 0, so we need to solve the quadratic equation:

If figure QRST is reflected across the x-axis and then translated 3 units down which of the following will be the coordinates for point R?
To find the coordinates of point R after the reflection and translation, we would need to know its original coordinates in the figure QRST. Then we could apply the above rules to get its new coordinates.
What are coordinates ?
Coordinates are numerical values that specify the position or location of a point in a given space. In mathematics, coordinates are often expressed as ordered pairs or triplets of numbers, which correspond to the distances of the point from a set of fixed reference points or axes.
Without seeing the figure QRST, it is not possible to give the exact coordinates for point R after the reflection and translation. However, we can use some general knowledge about the effects of reflection and translation on the coordinates of a point.
When a figure is reflected across the x-axis, the x-coordinates of all its points remain the same, but the y-coordinates are negated. That is, if a point has coordinates (x, y) before the reflection, its coordinates after the reflection will be (x, -y).
When a figure is translated down by 3 units, the y-coordinates of all its points are decreased by 3. That is, if a point has coordinates (x, y) before the translation, its coordinates after the translation will be (x, y - 3).
Therefore, to find the coordinates of point R after the reflection and translation, we would need to know its original coordinates in the figure QRST. Then we could apply the above rules to get its new coordinates.

9 inches of ribbon is needed for wrapping one present. How many presents can be wrapped with 8 yards of ribbon?
9 presents
16 presents
32 presents
45 presents
First, we need to convert 8 yards to inches since the measurement of ribbon needed for one present is given in inches.
1 yard = 36 inches (since 1 yard = 3 feet and 1 foot = 12 inches)
So, 8 yards = 8 x 36 = 288 inches.
To find out how many presents can be wrapped with 288 inches of ribbon, we divide the total length of ribbon by the length needed for one present:
Number of presents = Total length of ribbon ÷ Length of ribbon needed for one present
Number of presents = 288 ÷ 9
Number of presents = 32
Therefore, 32 presents can be wrapped with 8 yards (288 inches) of ribbon.
Hence, the answer is 32 presents.

Viet, Quinn, and Lucy are going to play Bingo, using a standard game set. They make some predictions before the game begins. The table shows how the numbers match with the letters B, I, N, G, and O.
PART A
Viet describes the probability of each number being called first. Quinn describes the probability of any particular letter being called first. Compare the probabilities.
Comparing the two probabilities, we can see that the probability of any particular letter being called first (1/5) is five times greater than the probability of any particular number being called first (1/75). This is because there are five letters and only one number will be called first.
What is the probability about?Viet's description of the probability of each number being called first can be determined as follows. There are 75 numbers in the set, and each number has an equal chance of being called first. Therefore, the probability of any particular number being called first is 1/75.
Quinn's description of the probability of any particular letter being called first can be determined as follows. There are five letters in the set, and each letter has 15 numbers associated with it. Therefore, the probability of any particular letter being called first is 15/75 or 1/5.
Comparing the probabilities, we can see that the probability of any particular letter being called first is greater than the probability of any particular number being called first. This is because there are fewer letters (5) than numbers (75), so the probability of selecting a particular letter is higher than the probability of selecting a particular number.
Therefore, Quinn's probability of any particular letter being called first is greater than Viet's probability of any particular number being called first.

Christopher needs to order some new supplies for the restaurant where he works. The restaurant needs at least 775 spoons. There are currently 355 spoons. If each set on sale contains 10 spoons, write and solve an inequality which can be used to determine
�
s, the number of sets of spoons Christopher could buy for the restaurant to have enough spoons.
According to the inequality, Christopher would need to purchase 35 + 10s 75 sets of spoons to ensure that the restaurant has enough of them.
Why does inequality matter?According to analysts, inequality promotes political dysfunction and slows down economic progress. Because wealthy households typically spend a smaller proportion of what they earn than do poorer households, concentrated earnings lower the amount of demand for goods and services. The economy may suffer if low-income families have fewer possibilities.
There are already 355 spoons available, but the eatery needs at least 75. Each set that is for sale includes 10 spoons.
Let s be the representation of each set. It will be demonstrated by:
35 + (10 × s) ≥ 75
35 + 10s ≥ 75
Collect like terms
10s ≥ 75 - 30
10s ≥ 45
Divide
s ≥ 45/10
s ≥ 4.5
The restaurant must have at least 5 sets.

A recipe calls for mixing 8/5 cups of blueberries and 7/5
cups of strawberries. The mix is divided equally among 18 items. What fraction of a cup is used for each item?
3 cups of fruit mix is divided equally among 18 items.
Each item will contain 1/6 cup of fruit mix.
How to find out what fraction of a cup is used for each item ?First we need to divide the total amount of fruit mix by the number of items.
The total amount of fruit mix is :
8/5 cups of blueberries + 7/5 cups of strawberries
= (8/5 + 7/5) cups
= 15/5 cups
= 3 cups
So, 3 cups of fruit mix is divided equally among 18 items.
To find the fraction of a cup used for each item, we need to divide 3 cups by 18:
Copy code
3 cups ÷ 18 = 1/6 cup
Therefore, each item will contain 1/6 cup of fruit mix.

calculate the ground distance if the map distance is 20 cm write your answer in kilometers
The ground distance, given the map distance and the scale, would be 5 kilometers.
How to find the distance?If the scale on a map is 1:25,000, it means that one unit of distance on the map represents 25,000 units of distance on the ground. If the map distance is 20 cm, we can find the ground distance as follows:
Convert the map distance from centimeters to kilometers:
20 cm = 0.2 m = 0. 0002 km
Find the ground distance using the scale:
Ground distance = Map distance / Scale
Ground distance = 0. 0002 km / ( 1 / 25,000 )
Ground distance = 0.0002 km x 25,000
Ground distance = 5 km

Mipl Analyze a Problem Without calculating, is the product of 7 and 5(3)/(4) greater than or less than 35 ? Explain.
The product is less than 35.
To analyze this problem without calculating, we can look at the factors involved in the product. The first factor is 7, and the second factor is 5(3)/(4).
The second factor, 5(3)/(4), is less than 5 because it is the product of 5 and a fraction less than 1.
When we multiply 7 by a number less than 5, the result will be less than 35.
Therefore, the product of 7 and 5(3)/(4) is less than 35.

David wants to build a pen for his goat. He wants the area of the pen to be 48 square feet. If the length and width of the pen are both whole numbers. What could be the perimeter of the pen. Alright I can’t figure it out please help
If the length and width of the pen are both whole numbers the possible perimeters for the pen are 98, 52, 38, 32, and 28.
To find the possible perimeters of the pen, we first need to find all the possible length and width pairs that would give us an area of 48 square feet. Since the length and width are whole numbers, we can start by listing out all the factors of 48:
1, 2, 3, 4, 6, 8, 12, 16, 24, 48
Each of these factors represents a possible length or width of the pen, and we can find the other dimension by dividing the area (48) by the first dimension. For example, if the first dimension is 1, then the other dimension is 48/1 = 48. However, we need to make sure that the second dimension is also a whole number.
Using this method, we can find all the possible length and width pairs:
1 x 48, 2 x 24, 3 x 16, 4 x 12, 6 x 8
Now we can calculate the perimeter for each of these pairs. The perimeter is the sum of the lengths of all four sides of the pen. Since the length and width are the same for a square pen, we can use the formula:
perimeter = 2(length + width)
For each pair, we can plug in the values for length and width to get the perimeter:
1 x 48: perimeter = 2(1 + 48) = 98
2 x 24: perimeter = 2(2 + 24) = 52
3 x 16: perimeter = 2(3 + 16) = 38
4 x 12: perimeter = 2(4 + 12) = 32
6 x 8: perimeter = 2(6 + 8) = 28
Therefore, the possible perimeters for the pen are 98, 52, 38, 32, and 28.

The value of x and y in the line segment are 6 and 6.5 units repsectively.
How to find length of line segment?The lines are three parallel lines cut by two transversal lines. The transversal lines that cut across the parallel lines have same length at intervals .
Using the information in the diagram let's find the value of x and y in the diagram.
Therefore,
2x + 1 = x + 7
2x - x = 7 - 1
x = 6 units
Therefore,
3y - 8 = y + 5
3y - y = 5 + 8
2y = 13
divide both sides by 2
y = 13 / 2
y = 6.5 units
Therefore,
