11xy-6x
24xy-16
24xy-16x
None of these choices are correct.
Answers
Answer:
Here,
the length=8x
the width =3y-2
We know that,
Area of rectangle=l×b
or, 8x × 3y-2
8x(3y-2)
24xy-16x
Hence, the correct answer is 24xy-16x

In Exercises 11 and 12, solids A and B are similar. Use the given information and scale factor k from solid A to solid B

12. The surface area of cone A is
150# square meters and k =
5
Answers
The surface area of solid B is 3,750 square meters.
How to calculate the surface area of solid?Since the solids are similar with a scale factor k from solid A to solid B, the ratio of their surface areas is k². Therefore, the surface area of solid B is:
Surface area of solid B = Surface area of solid A * k²
Substituting the given values, we get:
Surface area of solid B = 72 * 12²
Surface area of solid B = 10368 square centimeters.
Therefore, the surface area of solid B is 10,368 square centimeters.
Following the same approach as above:
Surface area of solid B = Surface area of solid A * k²
Substituting the given values:
Surface area of solid B = 150 * 5²
Surface area of solid B = 3750 square meters
Therefore, the surface area of solid B is 3,750 square meters.

the sum of four number is 20500.three of the numbers are 2341.578 and 10690.What is the fourth number?
Answers
Answer:
5216.844
Step-by-step explanation:
Let x be the fourth number.
We know that the sum of the four numbers is 20500:
2341.578 + 10690 + x + 2341.578 = 20500
Simplifying and solving for x:
x = 20500 - 2341.578 - 10690 - 2341.578
x = 5216.844
4x-k=17 solve for x
Answers
Answer:
k = -17 + 4x
Step-by-step explanation:
Simplifying
4x + -1k = 17
Reorder the terms:
-1k + 4x = 17
Solving
-1k + 4x = 17
Solving for variable 'k'.
Move all terms containing k to the left, all other terms to the right.
Add '-4x' to each side of the equation.
-1k + 4x + -4x = 17 + -4x
Combine like terms: 4x + -4x = 0
-1k + 0 = 17 + -4x
-1k = 17 + -4x
Divide each side by '-1'.
k = -17 + 4x

how many different choices of car does a person have if a particular model comes in 11 colors and 4 styles
Answers
Answer:
44 options
Step-by-step explanation:
In order to solve this problem you would simply need to multiply the options specifics together. In this scenario, these are the color and style. Therefore since the individual can choose from 11 colors and 4 styles you simply multiply 11 by 4. This is because every single color chosen has 4 styles to choose from, meaning that all 4 styles also have 11 colors to choose from and vice versa.
11 * 4 = 44
Therefore, we see that an individual looking to buy a car has a total of 44 options to choose from.

2 tons is what percent of 206 tons?
Answers
Answer:
0.971%
Step-by-step explanation:
A percentage is simply a ratio to a whole. If we assume 206 tons to be the whole, we can say this:
2 tons / 206 tons == 0.00971
And the percentage is out of 100 so:
0.00971 * 100 == 0.971 %
Hence, 2 tons is 0.971% of 206 tons.

Note are issued n the face value or the discounted value. When price of the note is the same as face value then it is known as issued on par/face value. When price of the note is the lower as face value then it is known as issued on discounted value.
Answers
Notes are commonly issued on discounted value when the issuer needs to raise funds quickly and is willing to accept a lower price for the note in exchange for immediate cash.
Notes can be issued either at their face value or at a discounted value.
A note is issued at its face value, the price of the note is the same as the face value of the note.
This is known as issuing the note at par value or face value.
A note is issued at a discounted value, the price of the note is lower than the face value of the note.
This is known as issuing the note at a discount.
The difference between the face value of the note and the discounted value is called the discount.
The investor who purchases the note at a discounted value will receive the face value of the note when it matures.
Notes may be issued at face value or at a discount from that amount.
The price of a note is equal to its face value when it is issued, or at face value.
The note will then be issued at face value or par value.
A note is sold for less than its face value when it is issued at a reduced price.
This is referred to as discounting the note's issuance.
The discount is the amount that separates the note's face value from its reduced value.
The face value of the note will be paid to the investor who paid the reduced price when the note matures.

The mean height of American women in their late twenties is about 64.5 inches and the standard deviation is about 2.5 inches. The mean height of men the same age is about 68.5 inches, with a standard deviation of about 2.7 inches. If the correlation between the heights of married heterosexual men and their wives is about r=0.5, what is the equation of the regression line of the the husbands height on the wife’s height in young couples?
Answers
Answer:
For married couples in their early 20s, the regression equation and the prediction of a husband's heightEquation: Y'=33.67+0.54*X'
Step-by-step explanation:
Given that
r=0.5x'=64.5Sx=2.5y'=68.5Sy=2.7General regression line equation is:
Y'=a+b*X'
Therefore, the slope of the regression line is equal to the linear correlation coefficient times the difference between the standard deviations of y' and x'.
\(b = r\times\frac{S_y}{S_x}\)
\(b = 0.5\times\frac{2.7}{2.5}\)
b = 0.54
The mean of the lowered by the slope and mean of x is the intercept with axis y.
\(a = y'-b\times x'\)
\(a = 68.5-0.54\times 64.5\)
\(a = 33.67\)
Now, putting the values of a and b in regression equation
So, we get
Y'=a+b*X'
Equation: Y'=33.67+0.54*X'

The volume of a tree stump can be modeled by considering it as a right cylinder. Lauren measures it’s height as 0.7ft and it’s radius as 20in find the volume of the stump in cubic inches. Round your answer to the nearest tenth if necessary
Answers
The volume of the tree stump is approximately 1005.3 cubic inches when rounded to the nearest tenth.
To calculate the volume of the tree stump, we can use the formula for the volume of a cylinder, which is given by:
Volume = π * r^2 * h
Given:
Radius (r) = 20 inches
Height (h) = 0.7 feet
First, let's convert the height from feet to inches since the radius is already in inches. There are 12 inches in 1 foot, so:
Height (h) = 0.7 feet * 12 inches/foot = 8.4 inches
Now, we can substitute the values into the volume formula:
Volume = π * (20 inches)^2 * 8.4 inches
Calculating the volume:
Volume = 3.14159 * (20 inches)^2 * 8.4 inches
≈ 3.14159 * 400 inches^2 * 8.4 inches
≈ 1005.3096 cubic inches
Rounding the volume to the nearest tenth:
Volume ≈ 1005.3 cubic inches
Therefore, the volume of the tree stump is approximately 1005.3 cubic inches when rounded to the nearest tenth.

In questions have a pair of similar three-dimensional objects. Find the surface area indicated. 2cm is the length of shape (the small shape) -surface area= =3.1 cm². the second shape has length of 6cm and surface area of b.
find b
Answers
The surface area of the second shape, denoted as b, is 9.3 cm².
To find the surface area of the second shape, we need to determine the relationship between the lengths and surface areas of the two shapes. Since the shapes are similar, the ratio of their surface areas will be equal to the square of the ratio of their lengths.
Let's denote the surface area of the second shape as B and the length of the second shape as L. We can set up the following proportion based on the given information:
(Surface area of the first shape)/(Surface area of the second shape) = (Length of the first shape)/(Length of the second shape)
Substituting the given values:
3.1 cm²/B = 2 cm/L
To find B, we can rearrange the equation:
B = (L * 3.1 cm²) / 2 cm
Now, we're given that the length of the second shape is 6 cm. Substituting this value:
B = (6 cm * 3.1 cm²) / 2 cm
Calculating:
B = (18.6 cm³) / 2 cm
B = 9.3 cm²
Therefore, the surface area of the second shape, denoted as b, is 9.3 cm².
