what percent is represented by the region that is shaded?​
the answer is not 333% or 333.33% or 333.3%

Answer:

To write 31415/10000 as a decimal you have to divide numerator by the denominator of the fraction.

We divide now 31415 by 10000 what we write down as 31415/10000 and we get 3.1415

Answer:

5

Step-by-step explanation:

We can set up an equation.
Let x be the number.

So 5x+5 would be equal to 30.

5x+5 = 30

Subtract 5 on both sides:
5x = 25

Divide by 5 on both sides:

x = 5

Answer:

Step-by-step explanation:

You want the slope-intercept form equation for the tangent line at point (π/6, 1) on the curve y = 2·sin(x).

The slope of the line at the point of tangency is the derivative of the curve at that point:

  y' = 2cos(x) = 2·cos(π/6) = 2(√3/2)

  m = √3 . . . . . approximately 1.7321

Solving the line's equation for b, we have ...

  y = mx +b

  b = y -mx = 1 -(√3)(π/6)

  b = 1 -π√3/6 . . . . . approximately 0.0931

The equation of the line is ...

  y = mx +b

  y = (√3)x +1 -(π√3)/6

Maddie wrote six different equations based on the triangle below.Four of the six equations that Maddie wrote are correct which are options A, D , E and F.

This is referred to as a polygon with three edges and three vertices.

Triangle ABC was given in the picture.

∠A = 60° and ∠B = 90° which is given in the figure

sin 60° = perpendiculer /hypotenuse

√3/2 = BC/10

BC = √3/2 × 10

BC = 5√3

tan 60° = perpendiculer /base

√3 =  5√3/AB

AB = 5√3/√3

AB = 5

sin 60° = 5√3/10 = √3/2

cos 60° = base / hypotenuse

cos 60° = 5/10 = 1/2

tan 60° = perpendicular /base

tan 60° = 5√3/5 = √3

cot 60° = 1 /√3

Therefore the equations which are correct are sin 60° =√3/2, cos 60° = 1/2, tan 60° = √3, and cot 60° = 1 /√3.

Answer:

y=1/5x+10

Step-by-step explanation:

The required percent​ decrease from 20 to 16 is given as 20%.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
To find the percent decrease, we can use the formula:

Percent Decrease = (original quantity - new quantity) / original quantity * 100%

Plugging in the values:

Percent Decrease = (20 - 16) / 20 * 100%

= 4 / 20 * 100%

= 20%

So, the percent decrease is 20%.

It falls between: The population mean is 13. 8. The population variance is 192. The population's standard deviation is 13.856.

A key measure of dispersion in statistics is population standard deviation. additional reading Statisticians compute variance to determine how various values inside a data collection interact to one another. While calculating the population variance, one may also compute the dispersion in relation to the population means.

The range: 15 - 2 = 13

The population mean is:

Mean = ( 2 + 10 + 15 + 2 + 12 + 13 + 7 + 3 + 8  ) / 9 = 8

The population variance ( S² or Sigma² ):

S ² = 1/9 · ( ( 2 - 8 )² + ( 10- 8 )² + ( 15 - 8 )² + ( 2 - 8 )² + ( 12 - 8 )² + ( 13 - 8 )² + ( 7 - 8 )² + ( 3 - 8 )² + ( 8 - 8 )²  )

S ² = 192

The population standard deviation:

S = √(S²) = √192 = 13.856

Answer: The actual area of the living room floor is 11 feet * 18.9 feet = 208.9 square feet. The estimated area of the living room floor is 12 feet * 20 feet = 240 square feet.

The difference in cost between the flooring to cover the actual area and the flooring to cover the estimated area of the living room floor is 240 square feet - 208.9 square feet = 31.1 square feet.

Therefore, the approximate difference in cost is 31.1 square feet * $8 per square foot = $248.80, which is closest to option (D) $250.

Answer:

x = 11

Step-by-step explanation:

both the petagons are similar so the sum of their sides will be same

i.e.

sum of ABCDE = sum of JKLMN

ABCDE = sum of all the five sides = 6+2+2+3+3 = 16

thus,

sum of JKLMN = 16

16 = x+1+1+1.5+1.5

16 = x+5

x = 16-5 = 11

The probability of guessing the top 3 horses in order in a field of 20 horses in the Kentucky derby is, Very low value approximately 0.000145

Probability is a mathematical term, which can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. The possibility that an event will occur is measured by probability.

Probability of Event = Favorable Outcomes/Total Outcomes = X/n

Given that,

There are total 20 horses,

The probability of guessing the top 3 horses in order = ?

The probability of guessing the top 3 horses in order in a field of 20 horses in the Kentucky Derby would be 1 in 20 x 19 x 18 = 6840.

This means that the probability of guessing the top 3 horses correctly would be 1/6840 or approximately 0.000145.

Answer:

2,810 feet

Step-by-step explanation:

Take a look at the diagram

There are two triangles formed with a common side AB

AB represents the vertical height of the plane = 5150 feet

AC represents the distance of car 1 from O

In ΔABC, m∠A = 90°, m∠ABC = 38°

Since the three angles of triangle must add up to 180°
90 + 38 +m∠C = 180

128 + m∠C = 180°

m∠C = 180 - 128 = 52°

In a right angle triangle where one side is the angle ∅, the ratio of the side opposite this angle to the side adjacent to the angle is tan∅

Using the values provided we get
tan(52°) = 5150/AC

AC= 5150/tan(52) = 4,023.62 feet ≈ 4024 feet

This is the horizontal distance of the first  car from the plane

Similarly for ΔABD

m∠D = 180 - (90 + 53) = 37°
tan(37) = 5150/AD

AD= 5150/tan(53) = 6,834.28 feet ≈ 6834 feet

This is the horizontal distance of the second car from the plane

The distance between the two cars = 6,834 - 4,024

= 2,810 feet

Answer: THE ANSWER IS 18/42 

Step-by-step explanation:

Answer: To project the population in 2020, we can use the linear trend line equation.

First, we need to find the equation of the line. Let's use the two given points, (2000, 220,000) and (2010, 252,000), to find the slope of the line:

slope = (252,000 - 220,000) / (2010 - 2000) = 32,000

Next, we can use the slope-intercept form of the line equation: y = mx + b, where m is the slope and b is the y-intercept.

Plug in the first point: 220,000 = 32,000 * 2000 + b

Solve for b: b = 220,000 - 32,000 * 2000 = -44,000,000

The equation of the line is: y = 32,000x - 44,000,000

Finally, we can use the equation of the line to project the population in 2020:

y = 32,000 * 2020 - 44,000,000 = 264,000

So, the projected population in 2020 is 264,000.

The variable y as the subject formula in the equation (2/3)y + v = x is y = (3/2)(x) - (3/2)(v)

Given the equation in the question;

(2/3)y + v = x

y = ?

Solve for y, we make 'y' the subject of the formula.

(2/3)y + v = x

Subtract v from both sides

(2/3)y + v - v = x - v

(2/3)y = x - v

Multiply both sides by 3/2

(3/2)(2/3)y = (3/2)(x - v)

y = (3/2)(x - v)

Apply distributive property.

y = (3/2)(x) - (3/2)(v)

It will take the inattentive driver 5.22 seconds to come to a complete stop, assuming the car's deceleration remains constant.

An inattentive driver traveling 16.0 m/s when he notices a red light ahead and his car is capable of decelerating at a rate of [tex]3.06 m/s^2[/tex]. To determine how much time it will take for the car to come to a complete stop, we can use the following equation of motion:

v = v0 + at

where v is the final velocity (in this case, 0 m/s), v0 is the initial velocity (16.0 m/s), a is the acceleration (negative, because the car is slowing down), and t is the time.

Rearranging and solving for t, we get:

t = -v0 / a

t = -16.0 / (-3.06)

t = 5.22 seconds

So, it will take the inattentive driver 5.22 seconds to come to a complete stop, assuming the car's deceleration remains constant. This time can be used to determine the minimum distance the driver needs to maintain between himself and the vehicle in front of him to avoid a collision.
