Answer:
(h+8)+5
Step-by-step explanation:
First, you need to add 8 to h, which is h+8 and then you need to add 5 to the result, which means you need to put parentheses around h+8 because you need to do that first. then your answer becomes (h+8)+5.
After adding 8 to h and then 5 to the result, the final value will be h + 13.
To perform the specified operations, you first need to add 8 to the value of h and then add 5 to the result. This can be expressed as a mathematical expression:
Result = (h + 8) + 5
Start with the value of h.
Add 8 to it, which gives you (h + 8).
Now, take the result from step 2 and add 5 to it, yielding the final result.
This process essentially means you're increasing the original value of h by 8, and then further increasing the updated value by 5. The final result will be h + 8 + 5, or simply h + 13.
So, the answer is that you will end up with a value equal to h + 13 after performing these operations.

Answer:
x = y^2 – 7
Step-by-step explanation:
The first step in finding the inverse of y = f(x) can be to write the equation x = f(y). The equation shown above is such an equation.
Answer:
[tex]x= y^2-7[/tex]
Step-by-step explanation:
We have been given an equation [tex]y=x^2-7[/tex]. We are asked to determine that which equation can be simplified to find the inverse of our given equation.
We know that to find inverse of an equation, the x and y-values are interchanged.
Let us interchange x and y values for our given equation.
[tex]x= y^2-7[/tex]
Therefore, the equation [tex]x= y^2-7[/tex] can be simplified to find the inverse of our given equation.
The diagonal of a rectangle is 25 in. The width is 15 in. What is the area of the rectangle?
The area of the rectangle is 300 square inches, calculated by multiplying the length (20 inches) by the width (15 inches).
To find the area of the rectangle, we can use the formula for the area of a rectangle, which is [tex]\( \text{length} \times \text{width} \).[/tex] However, we need to find the length of the rectangle first.
We are given that the width of the rectangle is 15 inches. Let's denote the length of the rectangle as [tex]\( l \).[/tex]
We know that the diagonal of a rectangle forms a right triangle with the length and width of the rectangle. Therefore, we can use the Pythagorean theorem to find the length of the rectangle.
The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the diagonal) is equal to the sum of the squares of the lengths of the other two sides (the length and the width).
So, we have:
[tex]\[ l^2 + 15^2 = 25^2 \][/tex]
Solving for[tex]\( l \):\[ l^2 = 25^2 - 15^2 \]\[ l^2 = 625 - 225 \]\[ l^2 = 400 \][/tex]
Taking the square root of both sides:
[tex]\[ l = \sqrt{400} \]\[ l = 20 \][/tex]
Now that we have found the length of the rectangle to be 20 inches, we can calculate the area:
[tex]\[ \text{Area} = \text{length} \times \text{width} \]\[ \text{Area} = 20 \times 15 \]\[ \text{Area} = 300 \, \text{square inches} \][/tex]
So, the area of the rectangle is 300 square inches.

Answer:
The following observation and calculations show that the iterative rule is correct.
Step-by-step explanation:
The second reason why these calculations are true is the fact these calculations represent geometric sequence.
Considering the data
200, 220, 242, 266.2, 292.82, 322.102,....
Any sequence is said to be the geometric sequence If the ratio between two consecutive terms remains constant - commonly known as common ration which is denoted by 'r'.
As the ratio between two consecutive terms remains constant. For example,
[tex]r=\frac{220}{200} =1.1, r=\frac{242}{220} =1.1, r=\frac{266.2}{242} =1.1[/tex]
So, the given sequence is a geometric sequence. In other words, in Geometric Sequence each term can be found in terms of multiplying the previous term by a constant factor which is 1.1.
So,
220 is obtained by multiplying 200 by 1.1.
i.e. 200×1.1 = 220
Also,
242 is obtained by multiplying 220 by 1.1.
i.e. 220×1.1 = 242
and so on...
Therefore, it is clear from the current observation and calculation that the iterative rule is correct.

A circle with circumference 6 has an arc with a 20 central angle,
What is the length of the arc?
Answer:
0.3 units
Step-by-step explanation:
The ratio of the length of the arc to the circumference of the circle is proportional to the ratio of the central angle to the sum of angle in a circle.
[tex]\frac{l}{6}=\frac{20}{360}[/tex]
This implies that:
[tex]l=\frac{20}{360}*6[/tex]
This simplifies to: [tex]l=\frac{20}{60}[/tex]
[tex]l=\frac{1}{3}=0.3 units[/tex]
Since the circumference of this circle is 6 units, the length of the arc formed is equal to 0.33 units
Given the following data:
Circumference = 6 units.
Central angle = 20°
How to calculate the length of the arc.Mathematically, if you want to determine the length of the arc formed by a circle, you will divide the angle subtended by the arc by 360 degrees and then multiply this fraction by the circumference of the circle as follows:
20/360 × 6 = 0.33 units.

all real values of x
all real values of x except x = 2
all real values of x except x = –3
all real values of x except x = 2 and x = –3
Answer:
The domain of the function (cd)(x) will be all real values of x except x = 2.
Step-by-step explanation:
The two functions are [tex]c(x) = \frac{5}{x - 2}[/tex] and d(x) = x + 3
So, (cd)(x) = [tex](\frac{5}{x - 2})(x + 3) = \frac{5(x + 3)}{x - 2}[/tex]
Then, for x = 2 the function (cd)(x) will be undefined as zero in the denominator will make the function (cd)(x) undefined.
Therefore, the domain of the function (cd)(x) will be all real values of x except x = 2. (Answer)

1. the sum of the first n odd positive integers is 64. what is the value of n ?
2. how many positive integers between 100 and 200 are divisible by 14 ?
please please help :(
Step-by-step explanation:
The sum of first n odd positive integer is n^2. The nth odd number is 2n-1.
i.e. 1 + 3 + ........+ (2n-1) = n^2.
1 + 3 +..........+ (2n-1) = 64
n^2 = 64
n = 8.
The positive integers between 100 and 200 which are divisible by 14 are 112, 126, 140, 154, 168, 182, 196. It is obtained by the multiples of 14 between 100 and 200.
100 = 7 * 14 + 2
200 = 14 * 14 + 4. The answer is 14 - 7 = 7
The seven numbers are
14 * 8 = 112
14 * 9 = 126
14 * 10 = 140
14 * 11 = 154
14 * 12 = 168
14 * 13 = 182
14 * 14 = 196

Describe how to solve the inequality 3x+4<13 using algebra tiles
The solution is x < 3.
Solution:
The given expression is 3x + 4 < 13.
To solve the given inequality.
3x + 4 < 13
Subtract 4 tiles on both sides of the inequality.
⇒ 3x + 4 – 4 < 13 – 4
⇒ 3x < 9
Divide by 3 tiles on both sides of the inequality.
⇒ [tex]\frac{3x}{3} =\frac{9}{3}[/tex]
⇒ x < 3
Hence the solution is x < 3.
Final answer:
To solve the inequality using algebra tiles, represent 3x+4 with tiles on one side and 13 units on the other, remove 4 units from both sides to get 3x < 9 and then divide the remaining 9 units into 3 groups to find x < 3.
Explanation:
To solve the inequality 3x+4<13 using algebra tiles, we follow these steps:
Start by representing the inequality with algebra tiles. Place 3 x-tiles (each representing 'x') and 4 unit tiles (each representing '1') on one side of a mat to model the expression 3x+4.
On the other side, place 13 unit tiles to represent the number 13.
To isolate the variable x, we need to remove the same number of unit tiles from each side. Remove 4 unit tiles from each side of the mat, which corresponds to Subtracting 4 from both sides of the inequality.
After removal, the inequality on the mat now shows 3x tiles on one side and 9 unit tiles on the other, representing the inequality 3x < 9.
Lastly, to find the value of one x-tile, divide the remaining unit tiles into 3 equal groups. Since there are 9 units left, each group will consist of 3 unit tiles, indicating that each x-tile is less than 3. This gives us the final inequality x < 3.
From this process, we've determined that for the original inequality 3x+4<13, the solution is x<3.
Which of the following representations are functions?
A only
A and B only
A and C only
A, B and C
Option 2: A and B only
Step-by-step explanation:
A: [tex]\{(0,9),(3,12),(-5,10),(5,10)\}[/tex]
The function can be represented in ordered pairs. Also, the x-values are not repeated and each has only one y-value. Hence, in this given ordered pair the values of x are not repeated and each has only one y-value.
Thus, A is a function.
B: [tex]y=x^{2} +10[/tex]
This is the general way of representing a function in which the input value (x-value) exactly related to one output value (y-value). Hence, in this given function the x-value has only one y-value.
Thus, B is a function.
C: The function can also be represented using tables in which each x-value is not repeated and has only one y-value. But, in this given table, the values of x (x=10) are repeated twice.
Thus, C is not a function.
Option 1: A only
Reason: A and B are the correct representations of the function.
This option 1 is not the correct answer.
Option 2: A and B only
Reason: A and B are the correct representations of the function.
This option 2 is the correct answer.
Option 3: A and C only
Reason: C is not a function. Only A and B are the correct representations of the function.
This option 3 is not the correct answer.
Option 4: A, B and C
Reason: Only A and B are the correct representations of the function and C is not a function.
This option 4 is not the correct answer.
What is a mean median and mode
Answer:
Mean, median, and mode are three kinds of "averages".
Step-by-step explanation:
Find the mean, median, mode, and range for the following list of values:
13, 18, 13, 14, 13, 16, 14, 21, 13
The mean is the usual average, so I'll add and then divide:
(13 + 18 + 13 + 14 + 13 + 16 + 14 + 21 + 13) ÷ 9 = 15
Note that the mean, in this case, isn't a value from the original list. This is a common result. You should not assume that your mean will be one of your original numbers.
The median is the middle value, so first I'll have to rewrite the list in numerical order:
13, 13, 13, 13, 14, 14, 16, 18, 21
There are nine numbers in the list, so the middle one will be the (9 + 1) ÷ 2 = 10 ÷ 2 = 5th number:
13, 13, 13, 13, 14, 14, 16, 18, 21
So the median is 14.
The mode is the number that is repeated more often than any other, so 13 is the mode.
The largest value in the list is 21, and the smallest is 13, so the range is 21 – 13 = 8.
mean: 15
median: 14
mode: 13
range: 8
Final answer:
Mean, median, and mode are basic statistical measures used to find the center of a data set. Mean finds the average, median identifies the middle value when data is ordered, and mode determines the most frequently occurring value.
Explanation:
Mean, median, and mode are measures of central tendency that describe the way in which different values cluster around a central point in a set of data.
The mean is the average of all the numbers in the data set. You calculate the mean by adding up all the numbers and dividing by the total number of values.
The median is the middle value of an ordered data set. If the data set has an odd number of values, the median is the exact middle number. If there is an even number of values, the median is the average of the two central numbers.
The mode is the value that appears most frequently in the data set. If no number repeats, the data set has no mode; if two or more numbers occur with equal frequency and more often than any other number, the dataset is multimodal, having several modes.
Each of these measures provides a different perspective on the typical value or center of a dataset, and is useful in various statistical analyses.

d = cost of food/med for dog
y = total cost/spent
What you know:
y = 6c + d [has 6 cats and 1 dog]
c = 2/3d - 5 [cost for cat is 5 less than 2/3 cost for dog]
y = $195
y = 6c + d

disjoint subsets A and B of a universal set U, except assume that n(U)=120, n(A)=45, and n(B)=50.
Then n(A′∪B)=
Answer:
n (A' U B ) = 75
Step-by-step explanation:
Here, given : n(U)=120, n(A)=45, and n(B)=50
As we know:
n (A ' U B) = n(A) − n (A∩B) ... (1)
Here, n(A) = 45
So, n( A') = n(U) - n(A) = 120 - 45 = 75
⇒ n(A') = 75
Now, as given A and B are disjoint sets.
⇒ n (A ∩ B) = Ф
So, (A' U B ) = A'
So, n (A' U B ) =n( A') = 75
⇒ n (A' U B ) = 75

John has 16 cups of apples and 15 cups of flour..
A pie needs 4 cups of apples and 3 cups of flour.
Apples: 16/4 = 4 he has enough apples to make 4 pies.
Flour: 15/3 = 5 he has enough flour to make 5 pies.
He can only make 4 pies, because of the amount of apples he has.
By making 4 pies, he uses all his apples, and he can make no cobblers.
x = 4 pies; y = 0 cobblers
Plot (4, 0).
A pie needs 2 cups of apples and 3 cups of flour.
Apples: 16/2 = 8 he has enough apples to make 8 cobblers.
Flour: 15/3 = 5 he has enough flour to make 5 cobblers.
He can only make 5 cobblers, because of the amount of flour he has.
By making 5 cobblers, he uses all the flour, and he can make no pies.
x = 0 pies; y = 5 cobblers
Plot (0, 5).
Now we calculate the amount of money.
At point (4, 0), 4 * $3 = $12
At point (0, 5), 5 * $2 = $10
Point (4, 0) shows a profit of $12 which is the most profit he can make.
A brand of crackers is sold in a box shaped like a rectangular prism. The box has a length of 13 cm, a width of 8 cm, and a height of 22 cm. What is the volume of the box of crackers?
Answer:
LxWxH
Step-by-step explanation:
Volume can be calculated by using the formula: (length) x (width) x (height)
In this particular question, you are given the length as 13cm, the width as 8cm, and the height of 22cm.
To obtain the volume, you should plug these numbers into the formula (length) x (width) x (height)
When plugged in, the equation should look like this: (13cm) x (8cm) x (22cm).
When 13 x 8 x 22 =2288cm
Since you are calculating the volume, the answer will be given in centimeters cubed, so your final answer will be 2,288cm^3
Hope this explanation helps :)
Answer:
I think the answer is 2288 cm
In order to find volume of a rectangular prism you have to do l x w x h (length times width times height)
13 x 8 = 104
104 x 22 = 2288
I hope its right sorry if nott:(

Which expression is equivalent to the expression 5(3x+4-x)
Final answer:
The equivalent expression to 5(3x+4-x) is obtained by combining like terms and distributing the 5, which results in 10x + 20.
Explanation:
To find an expression equivalent to 5(3x+4-x), we must first simplify the expression inside the parentheses. We combine like terms 3x and -x, which gives us 2x. Then, we distribute the 5 across the simplified expression within the parentheses:
5(3x+4-x) = 5(2x+4) = 5*2x + 5*4 = 10x + 20.
So the expression equivalent to 5(3x+4-x) is 10x + 20. This process involves simplifying expressions step by step, ensuring clarity and accuracy in mathematical computations. By systematically combining like terms and distributing constants, we obtain a concise and equivalent expression that represents the original expression's value.

Step-by-step explanation:
Quadratic Equations
The quadratic equation has the following general form
[tex]ax^2+bx+c=0[/tex]
It can be solved by several methods, including the well-known quadratic formula
[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
The question requires us to find a number that added with its reciprocal results 2 9/10. If x is the required number
[tex]\displaystyle x+\frac{1}{x}=2\ \frac{9}{10}=\frac{29}{10}[/tex]
Operating
[tex]\displaystyle \frac{x^2+1}{x}=\frac{29}{10}[/tex]
Rearranging
[tex]10(x^2+1)=29x[/tex]
[tex]10x^2-29x+10=0[/tex]
Comparing with the general quadratic equation, we have
[tex]a=10,\ b=-29,\ c=10[/tex]
Using the formula
[tex]\displaystyle x=\frac{29\pm \sqrt{(-29)^2-4(10)(10)}}{2(10)}[/tex]
[tex]\displaystyle x=\frac{29\pm \sqrt{441}}{20}=\frac{29\pm 21}{20}[/tex]
It gives us two possible solutions
[tex]\displaystyle \boxed{x=\frac{5}{2}, x=\frac{2}{5}}[/tex]
Both are valid solutions since
[tex]\displaystyle \frac{5}{2}+\frac{2}{5}=\frac{29}{10}[/tex]
