Step-by-step explanation:

The equation to calculate the sale price of the skirt, which is 's', given an original price 'p' and a discount of 20% on the original price would be s = p - (0.2 * p). This equation essentially subtracts the discount amount (20% of 'p') from 'p' to get the sale price 's'.

To calculating a sale price, which is a Mathematical exercise commonly carried out in financial and business scenarios. In this context, there's a 20% sale on skirts. Given that the original price of the skirt is 'p', and the discount is 20% of 'p', we can denote that as '0.2p'. If the sale price is represented as 's', the equation to calculate the sale price would be s = p - (0.2 * p). This equation essentially subtracts the discount amount (20% of the original price) from the original price to obtain the price after discount, which is the sale price.

the equation s = 0.80 * p. This accounts for a 20% reduction from the original price.

We need to determine the sale price using the original price (p) and the discount rate (20%).

Since the discount is 20% off, you can convert this percentage to a decimal
20% = 0.20.

To find the amount discounted, multiply the original price by 0.20,
Discount Amount = 0.20 * p.

Subtract the discount amount from the original price to get the sale price,
Sale Price (s) = p - 0.20 * p.

Alternatively, you can factor out p in the equation: s = p (1 - 0.20),
which simplifies to s = 0.80 * p.

Green thumbs sells lowest price. If you divide the$amount by the amount of roses, you'll get

Flora's : $13.50/3= $4.50 each rose

Green: $15/4= $3.75 each rose

Discount F: $23/6= $3.83 each rose

Answer:

Spencer will pay off the item 3 months sooner if he pay $260 instead of $170 a month

Step-by-step explanation:

Total Amount = $1880

Down Payment = 20%

Monthly payment = $170

if Monthly payment increased from $170 to $260, How many months sonner Spencer will pay off?

So, First calculate the down payment

Down payment = 20% of 1880

                          = (20/100) * 1880

                         = 376

Amount left to be paid = 1880 - 376

                                     = 1504

Total months to pay off for Spencer if he pay's $170 a month:

1504/170 = 8.8 ≈ 9 months

Total months to pay off for Spencer if he pay's $260 a month:

1504/260 = 5.7 ≈ 6 months

So, 9 -6 = 3 months

So, Spencer will pay off the item 3 months sooner if he pay $260 instead of $170 a month

Answer:

the equation to find the height is: x = 25 * tan(30°) and the height is x = 14.43 feet

Step-by-step explanation:

Length  of tree = 25 feet

Angle of elevation = 30 degrees

Equation for the height of tree=?

Let x represent the height.

We know that tan Ф = Perpendicular/Base

tan Ф = height of tree/ length of base

tan Ф = x/l

=> x = l*(tanФ)

x = 25 * tan(30°)

Now, putting values:

x= 25 * tan(30°)

x = 25 * 0.577

x = 14.43 feet

So, the equation to find the height is: x = 25 * tan(30°) and the height is x = 14.43 feet

The surface area-to-volume ratio is used in Biology to predict cell efficiency in eliminating wastes or procuring nutrients by diffusion.

In Biology, the surface area-to-volume ratio is used to predict which cells might eliminate waste or procure nutrients faster by diffusion. This ratio is calculated by dividing the surface area of a cell by its volume. Cells with a larger surface area-to-volume ratio are more efficient at exchanging materials with their surroundings.

For example, consider a small cell with a high surface area-to-volume ratio. This cell has a relatively larger surface area compared to its volume, which allows for faster diffusion of nutrients into the cell and waste products out of the cell. In contrast, a larger cell with a lower surface area-to-volume ratio has a relatively smaller surface area compared to its volume, resulting in slower diffusion.

By analyzing the surface area-to-volume ratio, we can predict which cells have a greater capacity for diffusion and therefore can eliminate wastes or procure nutrients at a faster rate.

Option A

Answer:

3.8 cm

Step-by-step explanation:

The arc length formula is s = r·Ф, where Ф is the central angle in radians.

Here, s = (2 cm)(1.9 rad) = 3.8 cm

The length of the arc intercepted by a central angle of 1.9 radians in a circle with a radius of 2 cm is 3.8 cm, calculated by multiplying the radius (2 cm) by the angle in radians (1.9).

A circle has a radius of 2 cm and we need to find the length (s) of the arc intercepted by a central angle of 1.9 radians. The formula to find the arc length 's' for a circle is s = r * Θ, where 'r' is the radius and 'Θ' is the central angle in radians. We have 'r' = 2 cm and 'Θ' = 1.9 radians.

To find the arc length 's', we simply multiply the radius by the angle:

s = 2 cm * 1.9 radians = 3.8 cm.

Therefore, the length of the arc intercepted by a central angle of 1.9 radians in a circle with a radius of 2 cm is 3.8 cm.

Answer:

There are 200 $8 tickets

There are 150 $10 tickets

There are 50 $12 tickets

Step-by-step explanation:

Let a = number of $8 tickets

Let b = number of $10 tickets

Let +c = number of $12 tickets

given:

(1) a+b+c = 400

(1) 8a+10b+12c = 3700

(1) a+b = 7c

--------------

This is 3 equations and 3 unknowns, so

it should be solvable

Substitute (3) into (1)

(1) 7c+c = 400

(1) 8c= 400

(1) c = 50

Plug this value into (2)

(2) 8a+10b+12*50= 3700

(2) 8a+10b+600= 3700

(2) 8a+10b= 3100

(2) 4a+5b= 1550

and

(1) a+b+c= 400

(1) a+b+50= 400

(1) a+b= 350

Multiply both sides of (1) by +4+

(1) 4a+4b= 1400

Subtract (1) from (2)

(2) 4a+5b+=+1550+

(1) -4a-4b= -1400

b= 150

and, since

(3) a+b= 7c

(3) a+150= 7*50

(3) a= 350-150

(3) a= 200

_________________

There are 200 $8 tickets

____________________________

check:

(2) 8*200+10*150+12*50= 3700

(2) 1600+1500+600= 3700

(2) 3700= 3700

Each type was sold are 200 for $8, 150 for $10, and 50 for $12 if the ticket prices were $8, $10, and $12, and the total income from ticket sales was $3700.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

At a college production of A Streetcar Named Desire, 400 tickets were sold. The ticket prices were $8, $10, and $12, and the total income from ticket sales was $3700.

Let x be the number of $8 tickets

Let y be the number of $10 tickets

Let z be the number of $12 tickets

From the data given in the question, we can frame three linear equation in three variables:

x + y + z = 400

8x + 10y + 12z = 3700

x + y = 7z

After solving the above equations by elimination method:

We get:

x = 200

y = 150

z = 50

Thus, each type was sold are 200 for $8, 150 for $10, and 50 for $12 if the ticket prices were $8, $10, and $12, and the total income from ticket sales was $3700.

The IQR is the difference between the lower and upper quartiles of the data and is a measure of the spread of the data.

Mid Term Exam:

First find the Median

The Lower quartile is the median of the bottom 5 values = 88.

The upper quartile is the median of the top 5 values = 100

So the IQR = 100 - 88 = 12.

b=-.5

Step-by-step explanation:

The value of b in the equation 12 - b = 12.5 is determined by subtracting 12 from both sides and then multiplying by -1, resulting in b = -0.5.

The student is asking to solve for b in the equation 12 - b = 12.5. To find the value of b, you need to isolate the variable on one side of the equation. This is done by subtracting 12 from both sides, resulting in -b = 12.5 - 12, which simplifies to -b = 0.5. To get b by itself and not -b, you multiply both sides of the equation by -1, giving b = -0.5.
