To calculate the perimeter and volume of the small rectangular mirror, we'll use the given dimensions in inches and convert the final answer to centimeters.

First, let's calculate the perimeter of the front of the mirror:

Perimeter = 2 * (length + width)

Perimeter = 2 * (2.2325 in + 1.116 in)

Perimeter = 2 * 3.3485 in

Perimeter = 6.697 in

Now, let's convert the perimeter from inches to centimeters:

Perimeter_cm = Perimeter * 2.54 cm/in

Perimeter_cm = 6.697 in * 2.54 cm/in

Perimeter_cm = 17.00138 cm (rounded to 5 significant figures)

Next, let's calculate the volume of the mirror:

Volume = length * width * thickness

Volume = 2.2325 in * 1.116 in * 0.041 in

Volume = 0.10137243 in^3

Now, let's convert the volume from cubic inches to cubic centimeters:

Volume_cm = Volume * (2.54 cm/in)^3

Volume_cm = 0.10137243 in^3 * (2.54 cm/in)^3

Volume_cm = 1.66487136112 cm^3 (rounded to 6 significant figures)

Therefore, the perimeter of the front of the mirror is approximately 17.001 cm and the volume of the mirror is approximately 1.66487 cm^3.

Hello !

Answer:

\(\boxed{\sf Triangle\ ABC\ is\ not\ right-angled.}\)

Step-by-step explanation:

Given :

The perimeter of triangle ABC is 25cm.

Moreover, this perimeter is equal to \(\sf AB+AC+CB\).

Therefore, we have \(\sf AB+AC+CB=25\)

Let's replace AB and BC with their values :

\(\sf 8.5+6.3+AC=25\)

\(\sf AC+14.8=25\)

Now let's substract 14.8 from both sides :

\(\sf AC=25-14.8\\\boxed{\sf AC=10.2cm}\)

Furthermore, according to the Pythagorean Theorem, if the triangle is right-angled, then the square of the hypotenuse of the triangle is equal to the sum of the squares of the other two sides.

The hypotenuse is the largest side, so in this triangle, it is AC.

\(AC^2\ne AB^2+BC^2\)

Triangle ABC is not right-angled.

Using exponential function concepts, it is found that it represents a decay of 19.4%.

A decaying exponential function is modeled by:

\(A(t) = A(0)(1 - r)^t\)

In which:

In this problem, the function is:

\(A(x) = 5800(0.806)^x\)

Since the rate of change is less than 1, it is a decay.

Then:

1 - r = 0.806.

r = 1 - 0.806 = 0.194.

The function represents a decay of 19.4%.

(a) The regular selling price of the watches is $330.

(b) The sale price for the store to break even is $330.

(c) The rate of markdown to sell the watches at the break-even price is 0%.

(a) To find the regular selling price of the watches, we need to consider the unit price the store paid for the shipment and apply the overhead and profit percentages.

The unit price the store paid is $250 less 40%, which can be calculated as:

Unit Price = $250 - (40/100) * $250

Unit Price = $250 - $100

Unit Price = $150

Now, we need to calculate the regular selling price by adding the overhead and profit percentages to the unit price.

Overhead = 65% of cost = (65/100) * $150 = $97.50

Normal profit = 55% of cost = (55/100) * $150 = $82.50

Regular Selling Price = Unit Price + Overhead + Normal Profit

Regular Selling Price = $150 + $97.50 + $82.50

Regular Selling Price = $330

Consequently, the timepieces' usual retail price is $330.

(b) To determine the sale price for the store to break even, we need to consider the cost of the watches, overhead, and normal profit percentages.

Break-even Price = Unit Price + Overhead + Normal Profit

Break-even Price = $150 + $97.50 + $82.50

Break-even Price = $330

Therefore, $330 should also be the sale price for the shop to break even.

(c) The rate of markdown to sell the watches at the break-even price can be calculated by finding the markdown percentage from the regular selling price.

Markdown = Regular Selling Price - Break-even Price

Markdown = $330 - $330

Markdown = $0

Since there is no markdown, the markdown rate required to sell the timepieces at a profit is 0%.

Answer:

Altogether they made $24 which is enough to earn $12 each

Step-by-step explanation:

Important information:

1 cup: $0.75

4 cups = 1 quart

8 quarts of lemonade altogether

If we are looking to solve for the revenue earned based on quarts, we must first solve for how much money they make on 1 quart

Since 1 cup sells for $0.75 and 4 cups makes up a quart, we must multiply

0.75 × 4 = 3

They make $3 per 1 quart

We are looking for the amount for 8 quarts though, not just 1. Again we must multiply

3 × 8 = 24

They will make $24 if they sell all 8 quarts

The questions ask if they will each earn $12

Since there are two of them, Miles and Lucy, we must divide revenue earned by 2, the number of people

24 ÷ 2 = 12

Answer:

25% increase

Step-by-step explanation:

To find percentage increase or decrease, use this equation:

{ [ ( Final ) - ( Initial ) ] / ( Initial ) } * 100

In this problem, 4 is the initial weight and 5 is the final weight. Now, let's plug these values into the problem to solve for percentage increase in the puppy's weight.

[ ( 5 - 4 ) / 4 ] * 100

[ 1 / 4 ] * 100

25%

So, the puppy's weight increased by 25% in three months.

The equation of the plane determined by the intersecting lines is:

0x + 7y + 9z - 19 = 0

What is the equation of the plane?

In mathematics, a plane is a flat, two-dimensional surface that extends infinitely in all directions. It is defined by an equation of the form Ax + By + Cz + D = 0, where A, B, and C are the coefficients of the normal vector to the plane and D is a constant. The coefficients A, B, and C determine the orientation of the plane in 3-dimensional space, and the constant D determines the distance of the plane from the origin.

The equation of the plane can be found by finding the cross product of the direction vectors of the two lines.

Let's start by finding the direction vectors of the two lines:

For line L1, the direction vector is:

d = <3, 2, -1>

For line L2, the direction vector is:

d = <-3, 1, -2>

Now, we can find the cross product of these two direction vectors:

n = d1 x d2 = <3, 2, -1> x <-3, 1, -2> = <0, 7, 9>

So the normal vector to the plane is <0, 7, 9>.

Next, we can find a point on either line to substitute into the general equation of a plane to find the equation of the plane:

Let's use the point from line L1:

x = -1 + 3 * 0 = -1

y = 2 + 2 * 0 = 2

z = 1 - 0 = 1

Now, we have a point (-1, 2, 1) and the normal vector <0, 7, 9>, which we can substitute into the general equation of a plane:

Ax + By + Cz + D = 0

where A, B, C are the components of the normal vector, and D is a constant.

Plugging in the values, we get:

0x + 7y + 9z - 19 = 0

So, the equation of the plane determined by the intersecting lines is:

0x + 7y + 9z - 19 = 0

The equation of the plane containing the two parallel lines v₁ = (0, 1, −8) t(6, 7, −5) and v₂ = (8, −1, 0) t(6, 7, −5) is 6x + 6y + 3z = 0.

What are parallel lines?

Parallel lines are coplanar infinite straight lines that do not intersect at any point in geometry. Parallel planes are planes that never meet in the same three-dimensional space. Parallel curves are those that do not touch or intersect and maintain a constant minimum distance.

To find an equation for the plane containing the two parallel lines v₁ = (0, 1, −8) t(6, 7, −5) and v₂ = (8, −1, 0) t(6, 7, −5),

We use the equation of a line: v = v₀ + tv₁

where v₀ and v₁ are points on the line and t is a real number.

Substitute the given points in for v₀ and v₁: v = (0, 1, −8) + t(6, 7, −5)

This equation of the plane is Ax + By + Cz = D, where A, B, C, and D are constants to be determined.

Equate the components:

0x + 1y - 8z = D....(1)

6x + 7y - 5z = D...(2)

Now, we subtract equation (1) from (2) and we get

6x - 0x + 7y - 1y - 5z + 8z = 0

6x + 6y + 3z = 0

Hence, the equation of the plane containing the two parallel lines v₁ = (0, 1, −8) t(6, 7, −5) and v₂ = (8, −1, 0) t(6, 7, −5) is 6x + 6y + 3z = 0.

x + 50 by x - 20

So, the area is

A(x) = (x + 50)(x - 20)

Here, we have

A(50) = (50 + 50)(50 - 20) = 3000

A(100) = (100 + 50)(100 - 20) = 12000
