Top answer:

let dimension of a rectangle= l × b Then l× b = 28 2(l+b) = 22 You solve the eq

Step-by-step explanation:

This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:

x^2-2y=3 - (x-2y=3) => x^2-x=0

Then we can factor the resulting equation and find the values of x:

x^2-x=0 => x(x-1)=0 => x=0 or x=1

Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:

x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1

Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:

x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1

Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.

Answer:

The first option, V ≈ 1607.7 in²

Step-by-step explanation:

Find the volume of the given cylinder.

\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)

Given:

r = 8 in

h = 8 in

π = 3.14

Find:

V = ?? in³

\(\hrulefill\)

Now solving,

Substitute the given values into the formula:

=> V = (3.14)(8)²(8)

Using a calculator to simplify:

=> V = 1607.68 in²

Rounded to the nearest tenth:

∴ V ≈ 1607.7 in²

Thus, the first option is correct.

Answer:

33.3%

Step-by-step explanation:

There are 3 sections the spinner can land on, and only one meets the requirement (less than 3, so the 2 section is the only one). Therefore the chance of landing on 2 is 1/3, or 0.333...... which can be converted into percentage by multiplying it by a hundred.

-0.333..... x 100 = 33.33333....

Answer:

12 and 78 are complementary.

80 and 100 are supplementary.

50 and 50 are neither.

Step-by-step explanation:

Hope it helps! =D

Both the interquartile range (IQR) and the range indicate that Bus 18 is the more consistent option. Its IQR of 16 and range of 16 are both smaller than the corresponding values for Bus 47, implying that the travel times of the students on Bus 18 are more consistent and have less variability.

To determine which bus is the most consistent, we can compare the measures of variability provided for each bus, namely the interquartile range (IQR) and the range.

The IQR is a measure of spread that represents the range of the middle 50% of the data. It is calculated by subtracting the first quartile (Q1) from the third quartile (Q3) of a dataset. The IQR provides information about the spread of the central portion of the data, ignoring outliers.

Looking at the given information:

For Bus 18:

IQR = 16

For Bus 47:

IQR = 24

Comparing the IQRs, we can conclude that Bus 47 has a larger IQR of 24, while Bus 18 has a smaller IQR of 16. A larger IQR indicates a greater spread or variability in the data, suggesting that the travel times of the students on Bus 47 vary more widely than those on Bus 18. Therefore, Bus 18 is more consistent or has less variability in travel times based on the IQR.

Additionally, we can also consider the range, which is the difference between the maximum and minimum values in a dataset. The range provides a measure of the total spread of the data, including the extreme values.

For Bus 18:

Range = 16

For Bus 47:

Range = 24

Comparing the ranges, we see that Bus 47 has a larger range of 24, while Bus 18 has a smaller range of 16. Similar to the IQR, a larger range indicates a wider spread or variability in the data, whereas a smaller range suggests less variability. Therefore, based on the range as well, Bus 18 is more consistent or has less variability in travel times compared to Bus 47.

In summary, both the interquartile range (IQR) and the range indicate that Bus 18 is the more consistent option. Its IQR of 16 and range of 16 are both smaller than the corresponding values for Bus 47, implying that the travel times of the students on Bus 18 are more consistent and have less variability.

Answer:

3x=-6

Step-by-step explanation:

Answer:

\( \frac{3x}{3 - 2x} \)

Step-by-step explanation:

Here,

f(x) = y

\(y = \frac{3x}{2x + 3} \)

or , swapping x with y

\(x = \frac{3y}{2y + 3} \)

now to solve for y we get

\(y = \frac{3x}{3 - 2x} \)

now we put f inverse x instead of y

\( {f}^{ - 1} (x) = \frac{3x}{3 - 2x} \)

Answer:

\(13.5 m^{2}\)

Step-by-step explanation:

area = length × width

       = 15m  × 9/10m

       = 15m  ×  0.9m

       = \(13.5 m^{2}\)

Answer:

\(\Huge \fbox{Area = 13.5 m^{2}$}\)

Step-by-step explanation:

To find the area of the baseboard, we need to multiply the length by the width:

To multiply these values, we can convert the width to a decimal by dividing the numerator (9) by the denominator (10):

Now we can multiply the length and width:

Therefore, the area of the baseboard is 13.5 m².

Answer:

Step-by-step explanation:

Xyla has all of her money to start so she has 1.

start by converting all fractions so they have a common denominator.

1/8 = 3/24

2/3 = 16/24

1/6 = 4/24

add these. it totals to

23/24

Now we subtract the whole: 1.

1 - 23/24 = 1/24

Xyla has 1/24 of her money left.

Answer:

1/24 of her money is remaining after the three purchases.

Step-by-step explanation:

To find what percentage of money Xyla has left, we must know what percent of her money she is spending. Our fractions are

1/8, 2/3, 1/6

to add these, we must find a common multiple between 8, 3, and 6. This would allow each denominator to be the same number.

A common multiple of the three is 24. Therefore, we multiply each fraction by the number that will allow the fractions to have a denominator of 24.

1/8*3=3/24

2/3*8=16/24

1/6*4=4/24

Then, we add the fractions:

3/24+16/24+4/24=23/24

Xyla has spend 23/24 of her money. Therefore, she has 1/24 of her money remaining.

Answer:

Mean = 16

Step-by-step explanation:

MEAN can be find bg the sum of all score divided by the amount of the score.

Mean = total amount / number of amount

Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39

= 128

number of amount = 2, 3, 5, 9, 17, 22, 31, 39

= 8

Then we can calculate mean as

Mean = 128/8

Mean = 16

Answer:

x squared = y

Step-by-step explanation:

Things can get more complicated, but based on the examples given, for an equation to be a function of x, it must have a single y, where the y is not raised to a power.

Option 1:  x=5

This equation doesn't have a y, so it isn't a function of x.

Option 2:  x = y squared + 9

This equation has y raised to a power, so it isn't a function of x

Option 3:  x squared = y

This equation has a y, and the y isn't raised to a power.  This is a function of x.

Option 4:  x squared = y squared + 16

This equation has y raised to a power, so it isn't a function of x

If the equations are graphed, the graphs must pass a vertical line test (a vertical line drawn anywhere should not intersect the graph more than once).

Option 1:  x=5

x=5 represents a vertical line, so it fails the vertical line test (the vertical line would overlap and intersect it infinitely many times).

Option 2:  x = y squared + 9

x = y squared + 9 is a sideways parabola.  A vertical line will cross it twice in several places

Option 3:  x squared = y

x squared = y is a parabola that opens upward.  It will pass the vertical line test

Option 4:  x squared = y squared + 16

x squared = y squared + 16 is a hyperbola (fancy graph shape) that won't pass the vertical line test.
