D. The volume is the product of the area of the base, (x+8)(x-3) and the height, 2x-5
Why?From the statement we know that the volume of the block is given by the following expression:
[tex](x+8)(x-3)(2x-5)[/tex]
We also know that we can calculate the volume of a block using the following equation:
[tex]Volume=AreaOfTheBase*Height[/tex]
So, from the given picture we know that:
[tex]AreaOfTheBase=Length*Width=(x+8)(x-3)\\Height=2x-5[/tex]
Hence, we have that the correct option is:
D. The volume is the product of the area of the base, (x+8)(x-3) and the height, 2x-5

The best measure of center for this data set is the
, and its value expressed up to one decimal place is
Answers
Answer:
Step-by-step explanation:
Before we can determine which measure of central tendency is the best we need to determined whether data set is skewed or not.
We can determine the skewness, if we know at least the median and the mean.
The array of the above data set is,
16,18,28,29,35,36,37,38,40,41,44,66,68,72
The Median of the above array is
\frac{37 + 38}{2} = \frac{75}{2} = 37.5
The mean is
\frac{16 + 18 + 28 + 29 + 35 + 36 + 37 + 38 + 40 + 41 + 44 + 66 + 68 + 72}{14} = \frac{532}{14} = 38
Since the mean and the median are not the same, the distribution is skewed.
<b>For a skewed distribution, the best measure of central tendency is the median.</b>
To one decimal place, the median is;
37.5
NB: If the distribution is not skewed then it is normal. In a normal distribution the median is equal to the mean. The mode is considered the best measure of center in this case.
Step-by-step explanation:
The median of a data set is the measure of center that is the middle value when the original data values are arranged in order of increasing (or decreasing) magnitude

A. Find 18% more than 200
B. Find 18% less than 200
Answers
Answer:
A. 236
B. 164
Step-by-step explanation:
18% of 200= 36
200+36=236
200-36=164
Answer:
A. 236
B. 164
Step-by-step explanation:
To solve it first you need to find what 18% of 200 is. To do that take the 18% and make it a decimal % is out of 100, so 18/100 = .18. Then to find how much 18% out of 200 is, multiply .18 * 200. You should get 36. Then you can add and subtract that from 200 to get 18% more and 18% less.

The factorized form of the given polynomial is (3x + 4)(3x - 4). Using one of the factorization methods of polynomial, the result is obtained.
What is the factorization of a polynomial?Writing a polynomial as the product of its factors (monomial, binomial or and so on) is called the factorization of the polynomial.
There are different methods of factorization. Some of them are the grouping method, GCF method, the difference of squares method, etc.
Factorizing the given polynomial:The given polynomial is [tex]9x^2-16[/tex]
Using the difference of squares method we can write the given polynomial as
[tex]9x^2-16 = (3x)^2-(4)^2[/tex]
We know that difference between any two squares is
[tex]a^2-b^2=(a+b)(a-b)[/tex]
So,
[tex]9x^2-16[/tex] = (3x + 4) (3x - 4)
Therefore, the factors of the given polynomial are (3x + 4) and (3x - 4).

Name the intersection of lines M and T
Answers

The intersection of lines M and T is the point where the lines meet or cross over each other.
To find the intersection, solve the system of equations formed by the two lines. Once you have the coordinates of the intersection point, name it accordingly.
Explanation:The intersection of two lines, M and T, is the point where the two lines meet or cross over each other.
To find the intersection, we need to determine the coordinates of the point where the lines M and T intersect.
We can find the intersection by solving the system of equations formed by the equations of the two lines.
The system of equations will have two variables (x and y) and we can solve for their values.
Once we have the coordinates of the intersection point, we can name it accordingly.
For example, if the intersection point has coordinates (3, 4), we can name it as point P(3, 4).

What is the equation, in point-slope form, of the line that has a slope of 6 and passes through the point (–1, –8)? a. y+8 = 6 (x+1 )
Answers
Answer:
y + 8 = 6(x + 1)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
here m = 6 and (a, b) = (- 1, - 8), hence
y - (- 8) = 6(x - (- 1)), that is
y + 8 = 6(x + 1)
ANSWER
[tex]y + 8=6(x + 1)[/tex]
EXPLANATION
The point-slope form of an equation is given by the formula:
[tex]y-y_1=m(x-x_1)[/tex]
Where
[tex](x_1,y_1)[/tex]
is a point on this line and
[tex]m[/tex]
is the slope of the line.
From the question, the line has slope 6 and passes through (-1,-8).
This means that
[tex]x_1=-1[/tex]
[tex]y_1=-8[/tex]
and
[tex]m = 6[/tex]
We substitute these values into the point-slope formula to get:
[tex]y- - 8=6(x- - 1)[/tex]
We simplify to get:
[tex]y + 8=6(x + 1)[/tex]

A rectangular prism and a cylinder have the same height. The length of each side of the prism base is equal to the diameter of the cylinder. Which shape has a greater volume?
The (blank) has the greater volume because the (blank) fits within the (blank) with extra space between the two figures.
Please fill in the blanks
Answers
Answer:
Filling in the blanks: (rectangular prism) (cylinder) (rectangular prism)
The cylinder has the greater volume because the cylinder fits within the rectangular prism with extra space between the two figures.
A prism is a three-dimensional object.
There are triangular prism and rectangular prism.
We have,
We can see this by comparing the formulas for the volumes of the two shapes.
The volume V of a rectangular prism with length L, width W, and height H is given by:
V = L x W x H
The volume V of a cylinder with radius r and height H is given by:
V = πr²H
Now,
We are told that the length of each side of the prism base is equal to the diameter of the cylinder.
Since the diameter is twice the radius, this means that the width and length of the prism base are both equal to twice the radius of the cylinder.
So we can write:
L = 2r
W = 2r
Substituting these values into the formula for the volume of the rectangular prism, we get:
V prism = L x W x H
V prism = 2r x 2r x H
V prism = 4r²H
Substituting the radius and height of the cylinder into the formula for its volume, we get:
V cylinder = πr^2H
To compare the volumes,
We can divide the volume of the cylinder by the volume of the prism:
V cylinder / V prism = (πr²H) / (4r²H)
V cylinder / V prism = π/4
π/4 is greater than 1/1,
Thus,
The cylinder has a greater volume.
The cylinder fits within the rectangular prism with extra space between the two figures because the cylinder is inscribed within the prism, meaning that it is enclosed within the prism but does not fill it completely.

The area of a garden is given by the trinomial g2 - 2g - 24. The garden’s length is g + 4. What is the garden’s width?
Answers
Final answer:
To find the garden's width, factor the area trinomial to match the given length of the garden. The width is represented by the other factor, which in this case is g - 6.
Explanation:
The area of a garden is given by the trinomial [tex]g^2[/tex] - 2g - 24, and the garden's length is g + 4. To find the garden's width, we need to factor the trinomial such that it is the product of two expressions, one of which must be the length (g + 4).
Factoring [tex]g^2[/tex] - 2g - 24, we look for two numbers that multiply to -24 and add up to -2. These numbers are -6 and +4. So, we can factor the area trinomial as:
(g - 6)(g + 4) = [tex]g^2[/tex] - 2g - 24.
Since the length of the garden is g + 4, the other factor, g - 6, must represent the width of the garden. Thus, the garden's width is g - 6.

What is the solution to both systems A and B?
Answers
Answer:

Step-by-step explanation:
The solution to the both system of equations A and B are (3.875, 2.375) for system A and (4.133, 2.289) for system B.
What does a System of Linear Equations define?Linear equations involve one or more expressions including variables and constants and the highest exponent of the variable is 1.
System of linear equations involve two or more linear equations.
Consider system A.
x + 3y = 11
15x − 3y = 51
Adding both equations,
16x = 62
x = 3.875
3y = 7.125
y = 2.375
Consider system B.
x + 3y = 11
15x = 62 ⇒ x = 4.133
3y = 6.867
y = 2.289
Hence the solutions are (3.875, 2.375) for system A and (4.133, 2.289) for system B.
