In the first week of July, a record 1,040 people went to the local swimming pool. In the second week, 110 fewer people went to the pool than in the first week. In the third week, 130 more people went to the pool than in the second week. In the fourth week, 332 fewer people went to the pool than in the third week. What is the percent decrease in the number of people who went to the pool over these four weeks?

The slope is 6.25, it means that her day pay increases by $6.25 for each computer sold

A general linear equation in the point-slope form is written as:

y = a*x + b

Where y and x are the two variables, a is the slope, and b is the y-intercept.

In this case, the linear equation is:

P(x) = 6.25*x + 75

We know that P(x) represents her pay, and x represents the amount of computers she sold.

Here we can see that the slope is 6.25, it means says how much her pay increases per computer sold.

Answer:

156

Step-by-step explanation:

36*3=108

8*-6=-48

108-(-48)=156

The solution of the expression 36(3) - 8(-6) will be 156.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the expression is 36(3) - 8(-6). the expression will be solved as below,

E = 36(3) - 8(-6)

E = 108 - ( -48 )

E = 108 + 48

E = 156

Number 1

Step-by-step explanation:

Number 1 it is a good answer

Explanation: Please give brainly if it's right!

First move all the x and y values on one side, and the constants on the other:

-x² + y = − 1

-x² - y = -7

Multiply -1 to the 2nd equation to change signs and then solve:

-x² + y = − 1

+x² + y = +7

2y = 6

y = 3

Plug in y to either equation (I plug into the first one)

-x² + 3 = − 1

-x² = -4

x = 2

For the given rectangular playpen, the perimeter of rectangular playpen is 150 feet and its area is at least 1000 square feet. then the length of the rectangular playpen is equal to at least 17.35 feet and at most 57.66 feet.

As given in the question,

For the given rectangular playpen,

Perimeter of rectangular playpen is equal to 150 feet .

Area of the rectangular playpen is equal to at least 1,000 squared feet .

Area = length × width

Let x be the length of the rectangular playpen .

Then its width is equal to 1000 / x.

Substitute the value of length and width in perimeter we get,

Perimeter of rectangular playpen = 2 ( length + width )

⇒ 150 = 2 [ x + (1,000/x)]

⇒ 150 / 2 = ( x² + 1,000 ) / x

⇒ x² + 1000 = 75x

⇒ x² -75x + 1,000 =0

Simplify quadratic equation using discriminant we get,

x = [ -( -75) ± √(-75)² - 4(1) (1,000) ] / 2(1)

⇒ x = (  75 ± √5625 - 4000) /2

⇒ x = (75 ± 40.31) / 2

⇒ x = 57.66 or 17.35

Therefore, for the given rectangular playpen, the perimeter of rectangular playpen is 150 feet and its area is at least 1000 square feet. then the length of the rectangular playpen is equal to at least 17.35 feet and at most 57.66 feet.

The measure of one of its angle is 150°

A Polygon is a two-dimensional closed figure made up of line segments (not curves). Polygon is a combination of two words, poly (which means many) and gon (which means shape) (means sides). To create a closed figure, at least three line segments must be connected end to end.

Given that

12 sided regular polygon

We can use the following formula to calculate the total number of degrees in any shape:

(n−2)⋅180

[Where n = number of sides]

(12−2)⋅180

(10)⋅180

=1800

So a 12-sided polygon has 1800 degrees. To calculate the measure of one angle, divide the total number of degrees (1800) by the number of sides, n.

(1800/12) = 150°

Therefore the measure of one of its angle is 150°

Step-by-step explanation:

to solve this equation you must first isolate the variable

that is n

so first

add 2n to both sides to get rid of n on one of the sides

-4n + 2n + 14 = -2 - 2n + 2n

-2n + 14 = -2

now subtract 14 to both sides to isolate n

-2n + 14 - 14 = -2 - 14

-2n = -16

now divide everything by -2 to isolate n completely

(-2n)/(-2) = (-16)/(-2)

n = 8

that is your answer

Answer:

A rectangular container with a square base, an open top, and a volume of 4,000 cm³. The minimum surface for the container is 1,200 cm².

The result is obtained by using the derivative.

These are the specified parameters:

Volume container is 4,000 cm³.

Let side of square base = a, and height of the container = h, so:

Volume = a × a × h

4,000 = a² h

       h = [tex]\displaystyle \frac{4000}{a^2}[/tex]     ... (1)

Surface area with a square base, an open top is area of a square + 4 times the vertical side.

Surface area (A) = a² + 4ah

Substitute the value of h = [tex]\displaystyle \frac{4000}{a^2}[/tex] into surface area.

A = a² + 4ah

A = a² + 4a ([tex]\displaystyle \frac{4000}{a^2}[/tex])

A = a² + [tex]\displaystyle \frac{16000}{a}[/tex]

So that the surface area is minimal, when the derivative and equate to 0.

A = a² + 16000 a⁻¹

A' = 0

2 a²⁻¹ + (-1) 16000 a⁻¹⁻¹

2a - 16000 a⁻²  = 0

2a - [tex]\displaystyle \frac{16000}{a^2}[/tex] = 0

2a = [tex]\displaystyle \frac{16000}{a^2}[/tex]

2a³ = 16000

 a³ = [tex]\displaystyle \frac{16000}{2}[/tex]

 a³ = 8000

 a = ∛8000

 a = 20

Surface area with a square base, an open top.

Substitute the value of a = 20

A = a² + [tex]\displaystyle \frac{16000}{a}[/tex]

A = 20² + [tex]\displaystyle \frac{16000}{20}[/tex]

A = 400 + 800

A = 1200

Answer:

The amount of cholesterol in 11 ounces of lobster is 220 mg

Step-by-step explanation:

The amount of cholesterol in 11 ounces of lobster can be calculated as follows

The first step is to convert all units of measure from ounce to mg

1 gram = 0.0352 ounce

Divide both sides by 0.0352 to get the value of 1 ounce

[tex]\frac{1}{0.0352}[/tex] gram = [tex]\frac{0.0352}{0.0352}[/tex] ounce

28.35 gram = 1 ounce

Since 1 gram equals 1000 milligrams, then multiply the left side by 1000 and change the unit of measure to milligram

28.35 [tex]\times[/tex] 1000 mg = 1 ounce

28350 mg = 1 ounce

Convert 3.6 ounces to milligrams

3.6 ounces = 3.6 [tex]\times[/tex] 28350 mg

3.6 ounces = 102060 mg

Convert 11 ounces to milligrams

11 ounces = 11 [tex]\times[/tex] 28350 mg

11 ounces = 311850 mg

Since there are 72 mg of cholesterol in a 3.6 ounces serving of lobster, then the ratio equation to follow is

[tex]\frac{72}{102060}=\frac{x}{311850}[/tex]

Where x is the amount of cholesterol in 11 ounces of lobster

Multiply both sides by 311850 to isolate x

[tex]\frac{72}{102060}\times 311850=\frac{x}{311850}\times 311850[/tex]

[tex]\frac{22453200}{102060} =x[/tex]

Simplify the left side of the equation

220 = x

Since the value of x is 220, then the amount of cholesterol in  11 ounces of lobster is 220 mg

The new coordinate after the given composite translation (x,y) → (x-5,y+5) will be (x+3,y+12).

Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.

Reflection is a mirror image of a graph about any axis.

If we reflect any graph about y = x then the coordinate will interchange it that (x,y) → (y,x).

As per the given translation rule,

(x,y) → (x+8,y+7)

The next translation is (x,y) → (x-5,y+5)

The resultant translation will be,

(x,y) → (x+8,y+7) to (x+8-5,y+7+5)
