Answer:

1/2

Step-by-step explanation:

You can add fractions which have the same denominator. 3 and 6 share multiples and so can form a common denominator. 3 can become 6 by multiplying by 2. Multiply both numerator and denominator of 5/3 by 2. It becomes 10/6 +-7/6 =3/6=1/2

Answer:

Step-by-step explanation:

First step: calculate the difference:

[tex]\$246.95-\$199.95=\$47.00[/tex]

Second step: calculate the ratio of the difference and the original price:

[tex]\dfrac{\$47.00}{\$246.95}\approx0.1903219[/tex]

Third step: Convert to the percent:

[tex]0.190319\cdot100\%=19.0319\%\approx19\%[/tex]

The percent of change if the original price is $246.95 and the new price is $199.95 is 19.0%.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

The original price is $246.95 and the new price is $199.95.

Change in price = 246.95-199.95

= $47

The percentage of each value to the overall value when there are two or more values that sum up to 100 is the actual number.

The percent of change = (Original price-New price)/Original price ×100

= 47/246.95 ×100

= 4700/246.95

= 19.03

= 19.0%

Therefore, the percent of change with the given original price and the new price is 19.0%.

Answer:

26 of each

Step-by-step explanation:

To solve write this as an equation (35x)+(15x)=1300

For this case we have:

x: Variable representing the types of advance input

y: Variable representing the same-day entry types

We have according to the cost:

[tex]35x + 15y=1300[/tex]

According to the number of tickets:

[tex]x + y = 60[/tex]

We have a system of two equations with two unknowns:

[tex]35x + 15y = 1300\\x + y = 60[/tex]

We multiply the second equation by -35:

[tex]35x + 15y = 1300\\-35x-35y = -2100[/tex]

We add:

[tex]-20y = -800\\y = \frac {800} {20}\\y = 40.[/tex]

Thus, 40 same-day tickets were sold.

[tex]x + 40 = 60\\x = 60-40\\x = 20[/tex]

20 advance tickets were sold

Answer:

20 advance

40 same-day

Answer:

[tex]V_{box}=3u^{3}[/tex]

Step-by-step explanation:

The complete question is

If the box holds 24 of these sugar cubes what is the total volume of the box.

The sugar cubes are 1/2 x 1/2 x 1/2

The total volume of the box would be the volume of each sugar cube multiplied by 24, because the box is formed by those 24 sugar cube.

The volume of one sugar cube

[tex]V_{cube}=\frac{1}{2}\times \frac{1}{2} \times \frac{1}{2}=\frac{1}{8} u^{3}[/tex]

We have 24 of them, so the volume of the whole box is

[tex]V_{box}=24\frac{1}{8}u^{3}\\ V_{box}=3u^{3}[/tex]

Therefore, the volume of the box is

[tex]V_{box}=3u^{3}[/tex]

To find the total volume of the box holding 24 sugar cubes, calculate the volume of a single sugar cube and multiply by 24.

The total volume of the box can be determined by finding the volume of a single sugar cube and multiplying it by the number of cubes in the box. Since the question does not provide specific dimensions of the sugar cube, let's assume the cube has sides of 1 cm. The volume of a cube is found by cubing the length of a side. So, the volume of a single sugar cube is 1 cm x 1 cm x 1 cm = 1 cubic cm. Since the box holds 24 sugar cubes, the total volume of the box is 24 cubic cm.

Answer:

Expression for Base Area is 16y²  and height of the prism is y² + y + 3.

Step-by-step explanation:

Given: Expression for volume of a prism = [tex]16y^4+16y^3+48y^2\:cubic\:units[/tex]

To find: Expression for the Base area and Height of the Prism.

We know that

Volume of a prism = Base Area × height

So we need to factorize given expression of volume into two factors in which 1st is for Base area and 2nd is for Height of the prism.

[tex]Volume=16y^4+16y^3+48y^2[/tex]

Take 16y² common from each terms, we get

[tex]Volume=16y^2(y^2+y+3)[/tex]

It is factorized in two factors,

So,

Base Area = 16y²

Height = y² + y + 3

Therefore, Expression for Base Area is 16y²  and height of the prism is y² + y + 3.

Answer:

Choosing the "best" measure of center. Mean and median both try to measure the "central tendency" in a data set. The goal of each is to get an idea of a "typical" value in the data set. The mean is commonly used, but sometimes the median is preferred.

Step-by-step explanation:

Final answer:

To compare data sets, one must consider whether to use the mean or the median. The mean is suitable for symmetric, outlier-free distributions, while the median is better for skewed data or data with outliers.

Explanation:

Comparing Data Sets Using Measures of Center

When comparing data sets to understand the center, it's crucial to choose the most appropriate measure of center. The mean and the median are the two most common measures. The mean, which is the sum of all values divided by the number of values, is a great indicator of the center for symmetric distributions without outliers. In contrast, the median, which is the middle value in an ordered list, is robust to outliers and is better for skewed distributions.

To determine which measure to use, consider whether the data contain outliers or extreme values that could heavily influence the mean. If so, the median would be a better representation of the center. Moreover, the shape of the data set (symmetrical vs. skewed) and the presence of outliers or extreme values are crucial considerations. The median appears more suitable for skewed data sets, while the mean could be a more accurate measure for symmetric, outlier-free data.

Answer:

11.25

Step-by-step explanation:

The slope is [tex]\frac{3}{4}[/tex]

Using this we can find Δx and Δy.

The slope is Δy/Δx

And Δx is 15 since the number of units from 12 to 27 is 15.

So Δy/15 = [tex]\frac{3}{4}[/tex]

Multiply so they have common denominators.

4Δy/60 = [tex]\frac{45}{60}[/tex]

Multiply each side by 60 and solve.

4Δy = 45

Δy = 11.25

So the length of x is 11.25

Answer:

x = 3

Step-by-step explanation:

Combine the 3 fractions on the left side.

[ note x ≠ - 1, 0, + 1 as this would make the fractions undefined ]

Multiply the numerators/ denominators by the lowest common multiple of

x - 1, x + 1, x , that is x(x - 1)(x + 1), that is

[tex]\frac{x(x+1)}{x(x-1)(x+1)}[/tex] + [tex]\frac{2x(x-1)}{x(x-1)(x+1)}[/tex] - [tex]\frac{3(x-1)(x+1)}{x(x-1)(x+1)}[/tex] = 0

distribute and simplify the numerators

[tex]\frac{x^2+x+2x^2-2x-3(x^2-1)}{x(x-1)(x+1)}[/tex] = 0

[tex]\frac{x^2+x+2x^2-2x-3x^2+3}{x(x-1)(x+1)}[/tex] = 0

[tex]\frac{3-x}{x(x-1)(x+1)}[/tex] = 0

Andre saves more money than Elena after four weeks and after 6 weeks the savings of Andre and Elena is the same and this can be determined by forming the linear equation.

Given :

Let w represents the total number of weeks. So, the linear equation that represents the situatuion "Andre starts with $100 in his savings account and adds $5 per week" is:

S = 5w + 100

The linear equation that represents the situatuion "Elena starts with $10 in her savings account and adds $20 each week" is:

S' = 20w + 10

a) After four weeks the savings of Andre is given by:

S = 5(4) + 100

S = 20 + 100

S = $120

After four weeks the savings of Elena is given by:

S' = 20(4) + 10

S' = 80 + 10

S' = $90

So, Andre saves more money than Elena after four weeks.

b) Now, the number of weeks after which the savings of Andre and Elena are the same is:

5w + 100 = 20w + 10

Simplify the above equation in order to determine the value of 'w'.

90 = 15w

w = 6

So, after 6 weeks the savings of Andre and Elena is the same.

The correct answer is D.[tex](5x^4-9x^3+7x-1)[/tex].

To simplify the given polynomial expression, one would typically look for like terms that can be combined. However, in the expression provided, there are no like terms. Each term in the expression [tex](5x^4, -9x^3, 7x, and -1)[/tex]has a different power of x or is a constant with no x term at all.

Since there are no common terms to combine, the expression is already in its simplest form. Therefore, the simplified expression remains as it was originally given:
