The store bought a pair of shoes for $25, and sold it for $45. What percentage was the markup?

Answer:

Negative 296 over 40

Step-by-step explanation:

4 5/8 into improper fraction is 37/8

-1 3/5 into improper fraction is -8/5

multiply across and you get -296/40

hope this is correct!

The correct answer is negative 296 over 40.

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now the given statement is,

four and five eighths times negative one and three fifths.

four and five eighths can be written in numerical form as,

4 5/8

convert it into improper fraction,

37/8

and negative one and three fifths can be written in numerical form as,

- 1 3/5

convert it into improper fraction,

- 8/5

So their product is given as,

37/8 * (- 8/5)

= - (37*8)/(8*5)

= - 296/40

i.e. negative 296 over 40.

Thus,The correct answer is negative 296 over 40.

The calculated value of the segment RS is 11

From the question, we have the following parameters that can be used in our computation:

The line segment (see attachment)

Using the sum of segments on a line theorem, we have

2x - 9 + x + 2 = 23

Where

RS = 2x - 9

Evaluate the like terms

So, we have

3x = 30

Divide

x = 10

Recall that

RS = 2x - 9

So, we have

RS = 2 x 10 - 9

Evaluate

RS = 11

Hence, the value of the segment RS is 11

Where are the answer choices?

Answer:

Step-by-step explanation:

Well, since the length of a month can vary in the number of days, this answer can also vary.

For example, February is only 28 days long, while December is 31 days long.

That being said, the average length of all 12 months is 30.436875 days, so if Denny left to another country on June 20th, he would most likely be back   July 19th of July 20th.

The value of the coin in 2019 would be approximately $132.

To calculate the value of the coin in 2019, we need to consider the annual increase rate of 16.9% from 2010 to 2019. We can use the compound interest formula to find the final value.

Starting with the initial value of $40 in 2010, we can calculate the value in 2019 as follows:

Value in 2019 = Initial value * (1 + Rate)^n

where Rate is the annual increase rate and n is the number of years between 2010 and 2019.

Plugging in the values:

Value in 2019 = $40 * (1 + 0.169)^9

Value in 2019 ≈ $40 * 2.996

Value in 2019 ≈ $119.84

Rounding the value to the nearest dollar, we get approximately $120. Therefore, the value of the coin in 2019 would be approximately $120.

However, please note that the exact value may vary depending on the specific compounding method and rounding conventions used.

Step-by-step explanation:

If the sales tax is 7%, the price of the sunglasses is  $61.6962

She has $70 gift card for a department store.

She buys a new glasses with her gift card.

The gift card had a remaining balance of $3.66.

Therefore,

amount she bought the sunglasses with tax = 70 - 3.66 = $66.34

Hence,

Sales tax = 7 / 100 × 66.34 = $4.6438

Therefore,

The original price before tax = 66.34 - 4.6438 = $61.6962

The point D on the graph shows that the rider has stopped moving.

What is a graph?

Graph is a line or curve of a line with represents the relation between two quantities.

There are two axis in graph each axis represents different quantity in a graph.

Two axis are X-axis and Y-axis. Generally quantity which increases gradually is kept on X-axis.

By using graph we can calculate many different things like in distance time graph if we calculate the area of the graph we can get the speed for that region.

Graph is a very helpful took as its a pectoral representation of data and we all know action speak louder than words so graphs can explain more information with less data.

Without knowing the total number of coins or the ratio between one dollar and two dollar coins in the jar, we cannot accurately determine the number of two dollar coins.

Amadi has a jar with both one dollar and two dollar coins. The question is asking how many of the coins in the jar are two dollar coins.
To determine the number of two dollar coins, we need more information. The question does not provide any details about the total number of coins or the ratio between one dollar and two dollar coins in the jar. Without this information, it is not possible to give an accurate answer.
If we assume that the jar contains a total of 100 coins, we can use algebra to solve for the number of two dollar coins.

Let's say the number of two dollar coins is x. Then, the number of one dollar coins would be 100 - x.
Since the value of the two dollar coins is double the value of the one dollar coins, we can set up the equation 2x + 1(100 - x) = total value of coins.
Simplifying the equation, we get 2x + 100 - x = total value of coins.
Combining like terms, we have x + 100 = total value of coins.
Since we don't know the total value of coins, we cannot solve for x. Therefore, we cannot determine the number of two dollar coins without additional information.

Answer:

D: Line M is a horizontal like with a slope of zero

Step-by-step explanation:

A vertical line would have the same x-value for coordinates but different y-values. It would also have an undefined slope.

Therefore, we can rule out A and B.

A horizontal line always has different x-values but the same y-value. It would also have a slope of zero.

Therefore, C is wrong and D is our answer.

Let's first find the slope of the line.

We can do this using the slope formula.

m = y₂ - y1 / x₂ - x₁

We take the second y minus the first y over the second x minus the first x.

So we have 9 - 9 / -1 - (-5).

So we have 0 / 4 which is 0.

So the slope of our line is zero.

We can eliminate any choices that say the slope is undefined.

Now, if we have a slope of zero, the line is flat or horizontal.

So we know line M has to be a horizontal or flat line with a slope of zero.

So our answer is D.

The required base of a solid is the region enclosed by an ellipse is 32 units.

An ellipse  has a flightiness short of what one, and it addresses the locus of focuses, the amount of whose good ways from the two foci of the circle is a steady worth. A basic illustration of the circle in our day to day routine is the state of an egg in a two-layered structure and the running following in a games arena.

the base of a solid is the region enclosed by an ellipse with a major axis of 6 along the y-axis and a minor axis of 4.

So, a= 6, b = 4

Base can be written as,

Base = \(\frac{1}{2}\int\limits^3_{-3}( {{\sqrt{4-\frac{4y^{2} }{9}}+\sqrt{4-\frac{4y^{2} }{9} } } )^2 } \, dx\) = 32 units

Thus, required base is 32 units.
