By substituting p = 10 into the equation -p + 60 = h + 10,000 and solving for h, we find that the constant h is -9,950.

The solution cam be solved as:

To find the value of constant h when p = 10 is a solution to the equation -p + 60 = h + 10,000, we substitute p = 10 into the equation and solve for h.

-p + 60 = h + 10,000

-10 + 60 = h + 10,000

50 = h + 10,000

h = 50 - 10,000

h = -9,950

The value of h is therefore -9,950.

The measure of these two angles are 80° and 100°

Step-by-step explanation:

Let

x and y ----> the measure of the same side angles

we know that

The sum of of the same side angles of two parallel lines is equal to 180 degrees

x+y=180° -----> equation A

x=y-20° ----> equation B

substitute equation B in equation A and solve for y

(y-20°)+y=180°

2y=180°+20°

y=200°/2

y=100°

Find the value of x

x=100°-20°=80°

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

Answer:

81

Step-by-step explanation:

We have to solve the following multiplication: (−27) (5−8)

First, we are going to simplify the second parenthesis, before performing the multiplication:

(−27) (5−8) = (−27)(-3) = 81.

The result is positive given that minus times minus equals plus.

Step 1: Solve the second parentheses

( − 2 7 ) ( 5 − 8 )

5 - 8 = -3

(-27)(-3)

Step 2: Multiply -27 by -3. Since these are both negative the answer will be positive

-27 * -3 = 81

Answer:

The angle of elevation is 60.3°

Step-by-step explanation:

* Lets revise the trigonometry functions

- In any right angle triangle:

# The side opposite to the right angle is called the hypotenuse

# The other two sides are called the legs of the right angle

* If the name of the triangle is ABC, where B is the right angle

∴ The hypotenuse is AC

∴ AB and BC are the legs of the right angle

- ∠A and ∠C are two acute angles

- For angle A

# sin(A) = opposite/hypotenuse

∵ The opposite to ∠A is BC

∵ The hypotenuse is AC

∴ sin(A) = BC/AC

# cos(A) = adjacent/hypotenuse

∵ The adjacent to ∠A is AB

∵ The hypotenuse is AC

∴ cos(A) = AB/AC  

# tan(A) = opposite/adjacent

∵ The opposite to ∠A is BC

∵ The adjacent to ∠A is AB

∴ tan(A) = BC/AB

* Now lets solve the problem

∵ The shadow of the tree is 20 feet long

- The shadow of the tree is on the ground

∵ The height of the tree is 35 feet tall

∴ The shadow of the tree and the height of the tree formed the legs of

  a right triangle

- The angle of elevation is opposite to the tree

∴ The shadow of the tree is the adjacent side of the angle of elevation

∴ The height of the tree is the opposite side of the angle of elevation

- let the name of the angle of elevation is Ф

∴ tan Ф = tree height/shadow length

∴ tan Ф = 35/20 = 7/4

∴ Ф = tan^-1(7/4) = 60.3°

* The angle of elevation is 60.3°

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.

Answer:

1024

Step-by-step explanation:

There are 4 bacteria at the start. We can make an equation to represent the phenomena explained in the question.

As it is written in the question that the bacteria culture doubles in every hour.

So,

Let t represent the unit of time

So the number of bacteria after t unit of time will be  

Number of bacteria after t unit of time=4*2^t

We have to calculate number of bacteria after 8 hours, so t = 8

Number of bacteria after 8 hours=4*2^8

=4*256

=1024

So the bacteria after 8 hours in the culture will be 1024..

The initial population of the bacterium cells was 4, and after 8 hours, there would be 1024 bacteria in the culture.

The initial population of the bacterium cells at the beginning of the experiment was 4 bacteria.

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.

https://brainly.com/question/38012507

#SPJ2

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.

Given : Radius of cylinder = 8 m

Height = 4 m

Volume of cylinder = πr²h cu. units

= 22/7 × 8 × 8 × 4 m³

= 804.57 m³ (approx.)

Curved surface area = 2πrh sq. units

= 2 × 22/7 × 8 × 4 m²

= 201.14 m² (approx.)

Total surface area = 2πr(r + h) sq. units

= 2 × 22/7 × 8 (8 + 4) m²

= 2 × 22/7 × 8 × 12 m²

= 603.43 (approx.)

Final answer:

The volume of a cylinder with a radius of 8 meters and a height of 4 meters is calculated using the formula V = πr²h, which yields approximately 804.25 cubic meters when using π ≈ 3.14159.

Explanation:

To calculate the volume of a cylinder with a given radius and height, you can use the formula V = πr²h. In the case of a cylinder with a radius of 8 meters and a height of 4 meters, plug these values into the formula to get:

V = π × (8 m)² × 4 m

V = π × 64 m² × 4 m

V = 256π m³

Since π (pi) is approximately 3.14159, you can further calculate the volume as:

V ≈ 256 × 3.14159 m³

V ≈ 804.2477 m³

Thus, the volume of the cylinder is approximately 804.25 cubic meters, when expressed with four significant figures.

Answer:

(a) Rectangle 1 and rectangle 2 are similar

(b) The perimeter of Rectangle 2 is k times the perimeter of Rectangle 1

(c) The area of Rectangle 2 is k² times the area of Rectangle 1

Step-by-step explanation:

* Lets talk about the similarity

- Two rectangles are similar if there is a constant ratio between

  their corresponding sides

- Rectangle 1 has dimensions x and y

- Rectangle 2 has dimensions kx and ky

- The ratio between their dimensions is:

 kx/x = k and ky/y = k, so there is a constant ratio K between their

 corresponding dimensions

(a) Rectangle 1 and rectangle 2 are similar

- The perimeter of any rectangle is 2(the sum of its two dimensions)

∵ Rectangle 1 has dimensions x and y

∴ Its perimeter = 2(x + y) = 2x + 2y ⇒ (1)

∵ Rectangle 2 has dimensions kx and ky

∴ Its perimeter = 2(kx + ky) = 2kx + 2ky

- By taking k as a common factor

∴ Its perimeter = k(2x + 2y) ⇒ (2)

- From (1) and (2)

∵ The perimeter of rectangle 1 = (2x + 2y)

∵ The perimeter of rectangle 2 = k(2x + 2y)

∴ The perimeter of rectangle 2 is k times the perimeter of rectangle 1

(b) The perimeter of Rectangle 2 is k times the perimeter of Rectangle 1

- The area of any rectangle is the product of its two dimensions

∵ Rectangle 1 has dimensions x and y

∴ Its area = x × y = xy ⇒ (1)

∵ Rectangle 2 has dimensions kx and ky

∴ Its area = kx × ky = k²xy ⇒ (2)

- From (1) and (2)

∵ The area of rectangle 1 = xy

∵ The area of rectangle 2 = k²xy

∴ The area of rectangle 2 is k² times the area of rectangle 1

(c) The area of Rectangle 2 is k² times the area of Rectangle 1

(a) Yes, Rectangle 1 and Rectangle 2 are similar. (b) It is proved that the perimeter of Rectangle 2 is k times the perimeter of Rectangle 1. (c) It is proved that the area of Rectangle 2 is [tex]k^2[/tex] times the area of Rectangle 1.

(a) Yes, Rectangle 1 and Rectangle 2 are similar. They are similar because each dimension of Rectangle 2 is k times the corresponding dimension of Rectangle 1, which means that all angles remain the same and the sides are in proportion.

(b) To prove that the perimeter of Rectangle 2 is k times the perimeter of Rectangle 1, we start by noting that the perimeter of a rectangle is the sum of all its sides. For Rectangle 1, the perimeter [tex]P_1[/tex] is given by :

[tex]P_1 = 2(x + y)[/tex]

For Rectangle 2, each dimension is multiplied by k, so the length becomes kx and the width becomes ky. Therefore, the perimeter [tex]P_2[/tex] of Rectangle 2 is:

[tex]P_2 = 2( kx + ky)[/tex]

[tex]P_2 = 2k(x + y)[/tex]

Since 2(x + y) is the perimeter of Rectangle 1, we can replace it with [tex]P_1[/tex], yielding [tex]P_2 =[/tex] [tex]kP1[/tex] . This shows that the perimeter of Rectangle 2 is indeed k times the perimeter of Rectangle 1.

(c) To prove that the area of Rectangle 2 is [tex]k^2[/tex] times the area of Rectangle 1, we consider the formula for the area of a rectangle, which is the product of its length and width.

The area [tex]A_1[/tex] of Rectangle 1 is:

[tex]A_1 = xy[/tex]

For Rectangle 2, the length and width are both multiplied by k, so the area [tex]A_2[/tex] is:

[tex]A_2 = (kx)(ky)[/tex]

When we multiply these out,

we get:

[tex]A2 =[/tex] [tex]k^2xy[/tex]

Since xy is the area of Rectangle 1, we can replace it with [tex]A_1[/tex], giving us [tex]A_2 =[/tex] [tex]k^2A_1[/tex] . This demonstrates that the area of Rectangle 2 is [tex]k^2[/tex] times the area of Rectangle 1.
