Answer:
208 cubic units
Step-by-step explanation:
The composite figure in the picture is composed of a triangular prism and a rectangular prism, both which can be calculated by the base * height formula.
First, let’s calculate the volume of the triangular prism:
The base is the area of the triangle base, which is dc/2, or 4*3/2, which is 6. Next, multiply the area of the base by the height “b”: 6 * 8 = 48.
Now, let’s calculate the volume of the rectangular prism:
The base is the rectangular base’s area, which is a*c, or 5*4, which is 20. Next multiply the base by the height “b”: 20 * 8 = 160
Now, add up the volumes of the rectangular and triangular prisms:
160 + 48 = 208 cubic units

How many tiles can fit in a rectangular floor with length 14 ft and width 6 ft if the the square tiles has an edge of 3/4 ft.
A rectangular floor with a length of 14 ft and a width of 6 ft, square tiles with an edge length of 3/4 ft, a total of 144 tiles can fit.
To determine how many square tiles can fit in a rectangular floor, we need to calculate the total number of tiles that can fit both horizontally and vertically.
Given:
Length of the rectangular floor = 14 ft
Width of the rectangular floor = 6 ft
Edge length of square tile = 3/4 ft
First, let's calculate the number of tiles that can fit horizontally:
Length of the rectangular floor / Edge length of square tile = 14 ft / (3/4 ft) = 14 ft × (4/3 ft) = 56/3 ft
Since we want a whole number of tiles, we need to round down or take the floor value:
Number of tiles horizontally = floor(56/3) = 18 tiles
Next, let's calculate the number of tiles that can fit vertically:
Width of the rectangular floor / Edge length of square tile = 6 ft / (3/4 ft) = 6 ft × (4/3 ft) = 24/3 ft
Again, we round down or take the floor value:
Number of tiles vertically = floor(24/3) = 8 tiles
To find the total number of tiles, we multiply the number of tiles horizontally by the number of tiles vertically:
Total number of tiles = Number of tiles horizontally × Number of tiles vertically = 18 tiles × 8 tiles = 144 tiles
Therefore, in a rectangular floor with a length of 14 ft and a width of 6 ft, square tiles with an edge length of 3/4 ft, a total of 144 tiles can fit.

Read the following prompt and type your response in the space provided.
Describe the relationship between the probability of an event and its complement.
If the probability of an event is 0.95, what is the probability of its complement?
The probability of the complement of the event is 0.05.
The complement of an event is the probability of that event not occurring. The relationship between the probability of an event and its complement is that they always add up to 1.
Therefore, if the probability of an event occurring is p, then the probability of its complement not occurring is 1-p.
In the case where the probability of an event is 0.95, the probability of its complement not occurring would be 1-0.95 = 0.05. This means that the probability of the complement of the event is 0.05.
This concept is important in probability theory and is used to calculate the probabilities of events and their complements. It allows us to consider all possible outcomes of a given situation and calculate the likelihood of each of them.

Hi can any one teach me this constant difference
The constant differences between the consecutive terms are 2 (a); 2 (b), -3 (c), 7 (d), 1(e), and 6(f).
How do you find the constant difference in a sequence of numbers?In math, the constant difference can be defined as the number that defines the pattern of a sequence of numbers. This means that number that should be added or subtracted to continue with the sequence.
Due to this, to determine the constant difference it is important to observe the pattern and find out the number that should be added. For example, if the sequence is 2, 4, 6, 8, there is a difference of 2 between each of the numbers and this is the constant difference.

solve for m + 1/4 < -1 2/5
The solution for the equation m + ( ¼ ) < -1 ( 2/5 ) is m < -1 ( 13/20 )
Given,
The equation: m + ( ¼ ) < -1 ( 2/5 )
We have to solve this:
m + ( ¼ ) < -1 ( 2/5 )
Subtract (1/4) from both sides:
That is,
m + ( ¼ ) – ( ¼ ) < -1 ( 2/5 ) – ( ¼ )
Here, ( ¼ ) – ( ¼ ) becomes 0.
Then,
m + 0 < -1 ( 2/5 ) – ( ¼ )
m < -1 ( 18-5 / 20 )
m < -1 ( 13/20 )
That is, the solution for the equation m + ( ¼ ) < -1 ( 2/5 ) is m < -1 ( 13/20 )

What is the solution to an equation?
In order to make the equation's equality true, the unknown variables must be given values as a solution. In other words, the definition of a solution is a value or set of values (one for each unknown) that, when used as a replacement for the unknowns, transforms the equation into equality.
We are given to find the roots of the following polynomial function :
f (x) = (x- 6)²(x + 2)²
We know that
the roots of a polynomial f(x) are given by the equation f(x) = 0.
Therefore, the roots of the given polynomial are given by
(x- 6)² =0 => x =6,6
(x + 2)² =0 , x =-2, -2
Thus, the required roots are
6 with multiplicity 2 and -2 with multiplicity 2.

Consider the system of equations above. Which of the following statements about this system is true?
Answer:
B; There is only one (x,y) solution and y is negative
Step-by-step explanation:
First, I graphed the two equations. Attached is an image of the equations graphed. Next, I looked for overlapping points. Wherever the two points overlap, there is a solution. When looking at the graph, we can see the lines overlap at only one point, (0,-1). Since y is negative, the answer must be B; there is only one (x,y) solution and y is negative.

\(\dfrac{\partial f}{\partial y} = x\ln(y) + \dfrac{xy}y + x\ln(z) = \boxed{x\ln(yz) + x}\)

Pepe is putting up a fence in his backyard to enclose a garden in form of a triangle. The garden
already has sides enclosed with eight feet and five feet of fence, respectively. What can you say
about the length of the third side?
A
The side needs a fence that is shorter than 8 ft. but not necessarily longer than 5 ft.
The side needs a fence that is longer than 3 ft. and shorter than 13 ft.
C
The side needs exactly 8 ft. of fence.
The side needs exactly 11 ft. of fence.
D
Answer:
We know that in a triangle, given two sides, the third one must be smaller than the sum of the given sides, but greater than their difference:
z < x + y
z > x - y
Therefore, the length of the third side will be between the difference and the sum of the other two sides. In our case:
x + y = 13
x - y = 3
Hence, the correct answer is: B) The side needs a fence that is longer than 3ft. and shorter than 13ft.

588.0528
I don't know.
Answer:
Ans; 58.80528
Step-by-step explanation:
Ans; ( 8.73) ( 42.1)(0.16) = (873) ( 421) (16) × 10^-⁵ = ( 367533) (16) × 10^-⁵ = 5880528 × 10^-⁵ = 58.80528
I hope I helped you^_^
The value of 0.16 x 42.1 x 8.73 after multiplying is 58.80528.
Given,
(0.16)(42.1)(8.73)
We need to multiply the decimal numbers.
How do we multiply decimal numbers?When we multiply decimal numbers the decimal point should be placed after the number of counts from the right side.
The number of counts is the sum of the counts of numbers before the decimal point of each decimal number from the right side.
Example:
1.23 x 134.5
Here,
In 1.23 there are two numbers before the decimal point.
In 134.5 there is one number before the decimal point.
So the count = 2 + 1 = 3
So,
There should be three numbers after the decimal point in 1.23. x 134.5.
1.23. x 134.5 = 165.435
Find 0.16 x 42.1 x 8.73 by multiplying.
We see that,
There are two numbers after the decimal point in 0.16
There are one numbers after the decimal point in 42.1
There are two numbers after the decimal point in 8.73
So,
2 + 1 + 2 = 5 numbers
There should be 5 numbers after the decimal point in 0.16 x 42.1 x 8.73
Now,
0.16 x 42.1 x 8.73 = 58.80528.
Thus the value of 0.16 x 42.1 x 8.73 is 58.80528.
