What is a rectangular prism?
A right rectangular prism is a box-shaped object, that is, a 3-dimensional solid which has six rectangular faces. Rectangular prisms can also be oblique - leaning to one side - but the side faces are parallelograms, not rectangles. A right rectangular prismz is also called a cuboid, box, or rectangular hexahedron. Moreover, "rectangular prism" and "right rectangular prism" are often used interchangeably.
The most common math problems related to this solid are of the type right rectangular prism calc find V or find A, where the letters stand for the Volume and Area, respectively. Let's see the necessary rectangular prism formula and learn how to solve those problems quickly and easily.
How do I find the volume of a rectangular prism?
The rectangular prism volume formula is:
volume = h × w × l,
where h is prism height, w is its width, and l is its length. To calculate the volume of a cardboard box:
Find the box length. For example, it can be equal to 18 in.
Determine its width. Let's say you measured 12 in.
Find out the rectangular prism height. Assume it's 15 in.
Calculate the cuboid volume. Using the rectangular prism volume formula above, we get volume = (18 × 12 × 15) in = 3240 in³.
How do I find the area of a rectangular prism?
The surface area of the cuboid consists of 6 faces - three pairs of parallel rectangles. To find the rectangular prism surface area, add the areas of all faces:
surface_area = 2 × (h × w) + 2 × (h × l) + 2 × (l × w) = 2 × (h × w + h × l + l × w),
where h is prism height, w is its width, and l is its length.
Let's see an example of how to solve the right rectangular prism calc - find A problem. We'll come back to our example with the box and calculate its surface area:
Calculate the rectangular prism surface area. First rectangle area is 15in × 12in = 180in², second 15in × 18in = 270in² and third one 18in × 12in = 216in². Add all three rectangles' areas - it's equal to 666 in² (what a number!) - and finally multiply by 2. The surface area of our cardboard box is 1332in².
Or save yourself some time and use our rectangular prism calculator.
Finally, let's attack the right rectangular prism calc find d (that is, the diagonal) type of problem.
How do I calculate the diagonal of a rectangular prism?
To determine the diagonal of a rectangular prism, apply the formula:
diagonal = √(l² + h² + w²)
where h is prism height, w is its width, and l is its length.

A mail-order computer business has four telephone lines. Let X denote the number of lines in use at a specified time. Suppose the pmf of X is as given in the accompanying table.Xp(x)00.11230.25 0.30.35a. Find the cdf F(x) of X. b. Calculate the probability of each of the following events: A = {fewer than two lines are in use},B= {at least two lines are in use}, C= {between one and five lines, inclusive, are in use}.
The probability of each event is: P(A) = 0.34 P(B) = 0.66 P(C) = 0.89
What is Probability ?
Probability can be defined as ratio of number of favourable outcomes and total number of outcomes.
To find the cdf F(x) of X, we can use the following formula:
F(x) = P(X ≤ x) = ∑ P(X = k) for k ≤ x
So we have:
F(0) = P(X ≤ 0) = P(X = 0) = 0.11
F(1) = P(X ≤ 1) = P(X = 0) + P(X = 1) = 0.11 + 0.23 = 0.34
F(2) = P(X ≤ 2) = P(X = 0) + P(X = 1) + P(X = 2) = 0.11 + 0.23 + 0.25 = 0.59
F(3) = P(X ≤ 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) = 0.11 + 0.23 + 0.25 + 0.3 = 0.89
F(4) = P(X ≤ 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) = 0.11 + 0.23 + 0.25 + 0.3 + 0.35 = 1
So the cdf F(x) of X is:
F(x) = 0 for x < 0
F(x) = 0.11 for 0 ≤ x < 1
F(x) = 0.34 for 1 ≤ x < 2
F(x) = 0.59 for 2 ≤ x < 3
F(x) = 0.89 for 3 ≤ x < 4
F(x) = 1 for x ≥ 4
b. To calculate the probability of the events A = {fewer than two lines are in use}, B = {at least two lines are in use}, C = {between one and five lines, inclusive, are in use}, we can use the cdf F(x) that we just found.
P(A) = P(X < 2) = F(1) = 0.34
P(B) = P(X ≥ 2) = 1 - P(X < 2) = 1 - F(1) = 1 - 0.34 = 0.66
P(C) = P(1 ≤ X ≤ 5) = F(5) - F(0) = 1 - 0.11 = 0.89
Therefore, the probability of each event is: P(A) = 0.34 P(B) = 0.66 P(C) = 0.89

the total area under the normal distribution curve is 0.9632.
How to find total area under the normal distribution curve?
To find the total area under the normal distribution curve, we can use the standard normal distribution table or a calculator with a normal distribution function. We need to find the areas to the left and right of the given z-scores and add them together.
First, we can find the area to the left of z = -2.15 using the standard normal distribution table or a calculator with a normal distribution function. The area to the left of z = -2.15 is the same as the cumulative probability of a standard normal distribution with a z-score of -2.15. Using a standard normal distribution table or a calculator, we find this area to be 0.0158.
Next, we can find the area to the right of z = 1.62 using the standard normal distribution table or a calculator with a normal distribution function. The area to the right of z = 1.62 is the same as the complement of the cumulative probability of a standard normal distribution with a z-score of 1.62. Using a standard normal distribution table or a calculator, we find the complement to be 0.0526. Therefore, the area to the right of z = 1.62 is 1 - 0.0526 = 0.9474.
Finally, we can add the area to the left of z = -2.15 and the area to the right of z = 1.62 to find the total area under the normal distribution curve:
S = area to the left of z = -2.15 + area to the right of z = 1.62
S = 0.0158 + 0.9474
S = 0.9632
Therefore, the total area under the normal distribution curve is 0.9632.

ITS TIMED PLS QUICK A gardener would like to add to their existing garden to make more flowers available for the butterflies that visit the garden. Her current garden is 45 square feet. If she added another rectangular piece with vertices located at (−21, 7), (−23, 7), (−21, 12), and (−23, 12), what is the total area of the garden? FOR 20 POINTS
10 ft2
55 ft2
225 ft2
450 ft2
Answer:
55ft2
Step-by-step explanation:
Find the area of the added rectangle
-23 - -21 = 2ft
12-7 = 5ft
A=bh = 2ft x 5ft = 10ft^2
add old area and new area
45ft^2 + 10ft^2 = 55ft^2
Answer:
55 ft2
Step-by-step explanation:
Since the x values are -21 and -23, it shows that they are 2 points away from eachother. They y values are 7 and 12 so they are 5 points away from eachother. Multiply 2 x 5 = 10 which is the area of the new garden. Since the old garden is 45 square feet, add 10 + 45 to get 55 square feet total.
g(x)= 0.5|x+1|. Edit the transformation Function. Use y= +A|x-C| + D
The transformation of the function G(x) in the form of y = +A| x - C| + D is -
y = 0.5| x + 1| + 0.5
What is a function?
In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.
To write the transformation of the function G(x) = 0.5|x+1| in the form y = +A |x - C| + D, we need to find the values of A, C, and D.
First, let's rewrite the given function in the form of |x - C| -
G(x) = 0.5 | x + 1| = 0.5| x - (-1)|
Comparing with the standard form y = A | x - C| + D, we have -
A = 0.5, C = -1
To find the value of D, we need to substitute a point on the graph of G(x) into the function and solve for D.
Let's use the point (-2, 1) -
G(-2) = 0.5|-2+1| = 0.5
So, we get D = 0.5.
Therefore, the transformation of the function is y = 0.5| x + 1| + 0.5.

The snow that will be gotten daily of the line plot is redistributed equally will be 1/2.
What is a line plot?A line plot, also known as a line graph, is a type of graph that displays information as a series of data points connected by straight lines. Line plots are often used to show how a particular variable changes over time or to compare two or more variables.
To create a line plot, you typically need to have a set of data points that represent the variable you want to graph. You then plot each data point on a graph, with the x-axis representing time or some other variable, and the y-axis representing the value of the variable you're graphing.
The snow that will be gotten daily of the line plot is redistributed equally will be:

How many three-digit positive integers x are there, such that subtracting
the sum of digits of × from x gives a three-digit number whose digits are all
the same?
Answer:
Let's call the three-digit number whose digits are all the same "n". We know that n must be between 111 and 999, inclusive.
Now let's consider a three-digit number x. We can write x as:
makefile
Copy code
x = 100a + 10b + c
where a, b, and c are the hundreds, tens, and one's digits of x, respectively. The sum of the digits of x is:
CSS
Copy code
a + b + c
If we subtract this sum from x, we get:
CSS
Copy code
100a + 10b + c - (a + b + c) = 99a + 9b
We want this to be equal to n, which means:
Copy code
99a + 9b = n
We know that n has three identical digits, so we can write:
makefile
Copy code
n = 111p
where p is a digit between 1 and 9. Substituting this into the equation above, we get:
CSS
Copy code
99a + 9b = 111p
11a + b = 37p
Since a and b are digits between 0 and 9, we can see that 37p must be between 0 and 99. The possible values of p are therefore 1, 2, and 3.
If p = 1, then 37p = 37, and we need to find two digits a and b such that 11a + b = 37. This gives us the solutions (a, b) = (3, 4) and (a, b) = (4, 3), which correspond to the numbers 343 and 434.
If p = 2, then 37p = 74, and we need to find two digits a and b such that 11a + b = 74. There are no such solutions since the largest possible value of 11a + b is 99.
If p = 3, then 37p = 111, and we need to find two digits a and b such that 11a + b = 111. This gives us the solution (a, b) = (10, 1), which corresponds to the number 1001. However, 1001 is not a three-digit number, so it does not count.
Therefore, the only two three-digit numbers that satisfy the conditions of the problem are 343 and 434. There are 2 such numbers.

Select the correct answer. Consider this absolute value function. f(x) = |x - 21 If function f is written as a piecewise function, which piece will it include? O x + 2, x > 2 -x - 2, x ≥ 2 -x + 2, x < 2 x - 2, x ≤ 2
The piecewise function for f(x) is f(x) = x - 2, x ≥ 2; -x + 2, x < 2, So the correct answer is option C.
Describe Function?In mathematics, a function is a rule that assigns each element of a set (called the domain) to a unique element of another set (called the range). Functions are a fundamental concept in mathematics and are used to describe relationships between variables, as well as to model and solve a wide range of mathematical problems.
A function is typically denoted using a letter such as "f", and is defined by an equation or formula that specifies how the input (or domain) values are transformed into output (or range) values. For example, the function "f(x) = 2x + 1" assigns each input value "x" to an output value equal to twice the input value plus one.
The absolute value function f(x) = |x - 2| can be written as a piecewise function by separating it into two cases:
Case 1: x - 2 ≥ 0 or x ≥ 2
In this case, the expression inside the absolute value bars becomes x - 2, so f(x) = x - 2.
Case 2: x - 2 < 0 or x < 2
In this case, the expression inside the absolute value bars becomes -(x - 2) = -x + 2, so f(x) = -x + 2.
Therefore, the piecewise function for f(x) is:
f(x) =
x - 2, x ≥ 2
-x + 2, x < 2
So the correct answer is option C.

Answer:
Step-by-step explanation:
The sum of the measures of angles DAC and CAB must equal the measure of angle DAB, since they are adjacent angles that share a common vertex, A. Therefore, we have:
(DAC) + (CAB) = (DAB)
Substituting the given values, we get:
(2y - 7) + (3y + 2) = (DAB)
Simplifying and solving for y, we get:
5y - 5 = (DAB)
y = (DAB + 5) / 5
Now we can find the measure of angle CAB by substituting y back into the given expression for CAB:
<CAB = (3y + 2) = 3[(DAB + 5)/5] + 2 = (3DAB + 17)/5
Therefore, the measure of angle CAB is (3DAB + 17)/5 degrees.

You would think its 5-x since it mentions "5" then the "n" BUT, if you think it about it, the problem is saying there taking 5 away FROM n, so, its x-5
3rd box: it mentions "sum" meaning addition, and "twice a number" meaning 2n. So, its 2n +9
4th box: it mentions " 2 times the sum of" pay attention to the "of" part because it signifies that the "2" part of this problem is multiplied by a conjunction of two terms. So its 2(n+9)
**you could use your deductive reasoning skills to figure it out. Since the problem mentions addition and since the answer choices leave you with one addition-related answer choice, it has to be 2(n+9)**
5th box: it mentions "product" meaning multiply, also mentions "3 times a number" meaning 3n. So its, (3n)(7)
6th box: After solving the previous 5 problems, the only answer is 5-n=x, so that's the answer for the 6th box

8. Compare the numbers in the following sequence and try to determine what the next number
should be.
6, 9, 18, 21, 42, 45, ?
Answer:
90
Step-by-step explanation:
this is the pattern: +3, *2, +3, *2, +3
so theoretically the next number would be 90.
The next number is 90.
If you observe the pattern the second number is +3 of the first number and the third number is ×2 of the second number following this pattern.
6+3=9
9×2=18
18+3=21
21×2=42
42+3=45
45×2=90
Therefore 90 is the right answer.
