Colin walks two times around at one and 1 7/8 mile trail there are park benches everywhere 1/4 mile long trail but there are no benches at the store or another trail how many park benches are there in the trail

Answers

Answer 1

Answer:

15

Step-by-step explanation:

2 x 1 and 7/8 = 3 and 6/8 miles

= 3.75 miles

Since there are park benches every 1/4 mile on the trail, we can find the number of benches by dividing the total length of the trail by the distance between the benches:

Number of benches = (3.75 miles) / (1/4 mile per bench)

Number of benches = 15

In a town, 60% of the police officers have ride-alongs with teenagers who want to join the police force. 258 police officers have ride-alongs. How many police officers are there altogether?

Answers

The total police officers there altogether given the percentage of police officers who have ride-alongs with teenagers is 430.

How many police officers altogether?

Percentage of police officers who have ride-alongs with teenagers = 60%

Number of Percentage of police officers who have ride-alongs = 258

Total police officers = x

So,

(Percentage of police officers who have ride-alongs with teenagers) of (Total police officers) = (Number of Percentage of police officers who have ride-alongs)

60% of x = 258

0.6 × x = 258

0.6x = 258

divide both sides by 0.6

x = 258/0.6

x = 430

Ultimately, there are 430 police officers altogether.

a car traveling at 30m/s comes to a stop in 5 seconds. What is the accerlation of this car

Answers

Answer: The acceleration of the car is -6 m/s²

Step-by-step explanation:

The acceleration of the car can be found by using the given below equation:

Acceleration = (final velocity - initial velocity) / time

Given:

Initial velocity (u) = 30 m/s

Final velocity (v) = 0 m/s

Time (t) = 5 seconds

Putting the values in the equation:

acceleration = (0 - 30) m/s / 5 s

acceleration = -30 m/s / 5 s

The areas of the triangles are listed below:

Triangle A: A = 30 cm²

Triangle B: A = 14 cm²

Triangle C: A = 15 cm²

Triangle D: A = 40.997 cm²

How to find the areas of the triangles

In this problem we have a composite figure in the form of a square and formed by three right triangles (A, B, C) and a non-right triangle (D). The area of each triangle must be found, the areas of the each right triangle can be determined by this formula:

A = 0.5 · b · h

Where:

A - Areab - Baseh - Height

And the area of the non-right triangle can be found by Heron's formula:

A = √[s · (s - a) · (s - b) · (s - c)]

s = 0.5 · (a + b + c)

Where:

s - Semiperimeter.a, b, c - Side lengths

First, determine the areas of the right triangles:

Triangle A

A = 0.5 · (10 cm) · (6 cm)

A = 30 cm²

Triangle B

A = 0.5 · (7 cm) · (4 cm)

A = 14 cm²

Triangle C

A = 0.5 · (3 cm) · (10 cm)

A = 15 cm²

Second, find the side lengths of the non-right triangle by Pythagorean theorem:

a = √[(10 cm)² + (6 cm)²]

a = 2√34 cm

b = √[(7 cm)² + (4 cm)²]

b = √65 cm

c = √[(3 cm)² + (10 cm)²]

c = √109 cm

Third, calculate the semiparameter of the non-right triangle:

s = 0.5 · (2√34 cm + √65 cm + √109 cm)

s = 15.082 cm

Fourth, calculate the area of the non-right triangle:

A = √[(15.082 cm) · (15.082 cm - 2√34 cm) · (15.082 cm - √65 cm) · (15.082 cm - √109 cm)]

A = 40.997 cm²

Find the distance between the points and graph please

Answers

Answer:

The distance formula is:

[tex]d = \sqrt{(x_2 - x_1)^2+ (y_2 - y_1)^2}[/tex]

Where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex]are the coordinates of the two points.

(-2, 5) & (0, -4):

[tex]d = \sqrt{(0 - (-2))^2+ ((-4) - 5)^2}=\sqrt{85}[/tex]

So the distance between (-2, 5) and (0, -4) is [tex]\sqrt{85}[/tex].

(0,-4) & (5, 3):

[tex]d = \sqrt{(5 - 0)^2+ ((3) - (-4))^2}=\sqrt{74}[/tex]

So the distance between (0,-4) and (5, 3) is [tex]\sqrt{74}[/tex]

(5, 3) & (-2, 5):

[tex]d = \sqrt{(5 - (-2))^2 + ((3) - 5)^2}=\sqrt{53}[/tex]

So the distance between (5, 3) and (-2, 5) is [tex]\sqrt{53}[/tex].

Answer:

[tex]\sqrt{85}\approx 9.23 \; \sf units\;(3\;s.f.)[/tex]

[tex]\sqrt{74}\approx 8.60\; \sf units\; (3\;s.f.)[/tex]

[tex]\sqrt{53}\approx 7.28\; \sf units \;(3\;s.f.)[/tex]

Step-by-step explanation:

The distance formula is a mathematical equation used to calculate the distance between two points in a coordinate system.

[tex]\boxed{\begin{minipage}{7.4 cm}\underline{Distance Formula}\\\\$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$\\\\\\where:\\ \phantom{ww}$\bullet$ $d$ is the distance between two points. \\\phantom{ww}$\bullet$ $(x_1,y_1)$ and $(x_2,y_2)$ are the two points.\\\end{minipage}}[/tex]

To find the distance between each set of two points, substitute the coordinates of the points into the distance formula and solve for d.

The distance between points (-2, 5) and (0, -4) is:

[tex]\begin{aligned}d&=\sqrt{(0-(-2))^2+(-4-5)^2}\\&=\sqrt{(2)^2+(-9)^2}\\&=\sqrt{4+81}\\&=\sqrt{85}\\&\approx 9.23 \; \sf units\;(3\;s.f.)\end{aligned}[/tex]

The distance between points (0, -4) and (5, 3) is:

Mr.Blackwell’s class is conducting an experiment to find the probability of pulling certain colors from a bag of 25 marbles. If 6 are purple, 3 are yellow, 7 are green, and the rest are black, what is the probability of drawing a purple and yellow if the marbles are not replaced after they are picked?

Answers

Answer:

Step-by-step explanation:

To find the probability of drawing a purple and yellow marble without replacement, we need to determine the number of favorable outcomes (purple and yellow marbles) and the total number of possible outcomes.

Step 1: Determine the number of purple marbles:

The given information states that there are 6 purple marbles.

Step 2: Determine the number of yellow marbles:

The given information states that there are 3 yellow marbles.

Step 3: Determine the total number of marbles:

The given information states that there are 25 marbles in total.

Step 4: Calculate the probability of drawing a purple and yellow marble:

When drawing without replacement, the probability of two events occurring is the product of their individual probabilities.

The probability of drawing a purple marble is: 6 purple marbles / 25 total marbles = 6/25.

After drawing a purple marble, the total number of marbles remaining is 24 (since one purple marble is already drawn).

The probability of drawing a yellow marble from the remaining marbles is: 3 yellow marbles / 24 remaining marbles = 3/24.

To find the probability of both events occurring (drawing a purple and yellow marble), we multiply their individual probabilities:

Probability of drawing a purple and yellow marble = (6/25) * (3/24) = 18/600 = 3/100.

Therefore, the probability of drawing a purple and yellow marble without replacement is 3/100.

Express in polar form 6√3 + 6i​

Answers

Answer:

Step-by-step explanation:

To express 6√3 + 6i in polar form, we first need to find the magnitude and argument of the complex number.

The magnitude (or modulus) of the complex number is given by the formula:

|z| = √(a^2 + b^2)

where a and b are the real and imaginary parts of the complex number, respectively.

In this case, a = 6√3 and b = 6, so:

|6√3 + 6i| = √((6√3)^2 + 6^2) = √(108 + 36) = √144 = 12

The argument (or angle) of the complex number is given by the formula:

arg(z) = tan^-1(b/a)

In this case, arg(z) = tan^-1(6/6√3) = tan^-1(1/√3) = π/6

Therefore, the polar form of 6√3 + 6i is:

12(cos(π/6) + i sin(π/6))

or

12e^(iπ/6)

Charlie the trainer has two solo workout plans that he offers his clients: Plan A and plan B. Each client does either one or the other (not both). On Wednesday there were 5 clients who did plan A and 6 who did plan B. On Thursday there were 3 clients who did plan A and 2 who did plan B. Charlie trained his Wednesday clients for a total of 7 hours and his Thursday clients for a total of 3 hours. How long does each of the workout plans last?

Answers

Plan A lasts for 0.5 hours, and Plan B lasts for 0.75 hours based on the given information and the solution to the System of equations.

To determine the duration of each workout plan, let's assume that both Plan A and Plan B have a fixed duration. Let's denote the duration of Plan A as "x" hours and the duration of Plan B as "y" hours.

From the given information, we can form the following equations:

On Wednesday:

5 clients did Plan A, so the total duration for Plan A is 5x hours.

6 clients did Plan B, so the total duration for Plan B is 6y hours.

The total training duration on Wednesday is 7 hours, so we have the equation: 5x + 6y = 7   ... Equation (1)

On Thursday:

3 clients did Plan A, so the total duration for Plan A is 3x hours.

2 clients did Plan B, so the total duration for Plan B is 2y hours.

The total training duration on Thursday is 3 hours, so we have the equation: 3x + 2y = 3   ... Equation (2)

We now have a system of equations (Equation 1 and Equation 2) that we can solve to find the values of x and y.

Multiplying Equation (1) by 2 and Equation (2) by 5 to eliminate the y variable, we get:

10x + 12y = 14   ... Equation (3)

15x + 10y = 15   ... Equation (4)

Multiplying Equation (3) by 3 and Equation (4) by 2 to create a new system of equations:

30x + 36y = 42   ... Equation (5)

30x + 20y = 30   ... Equation (6)

Subtracting Equation (6) from Equation (5), we can eliminate the x variable:

(30x + 36y) - (30x + 20y) = 42 - 30

16y = 12

y = 12/16

y = 0.75

Substituting the value of y into Equation (2), we can solve for x:

3x + 2(0.75) = 3

3x + 1.5 = 3

3x = 3 - 1.5

3x = 1.5

x = 1.5/3

x = 0.5

Therefore, the duration of Plan A is 0.5 hours, and the duration of Plan B is 0.75 hours.

Plan A lasts for 0.5 hours, and Plan B lasts for 0.75 hours based on the given information and the solution to the system of equations.

Let's calculate the slope. Pick 2 points. I'll choose (0,-3) and (3,0).

The slope should be positive; our line is pointing UP and as x increases, y increases.

Slope = rise/run = (y2-y1)/(x2-x1)

How many degrees should the contractor lower the ramp by in order to meet safety regulations?

Answers

The contractor should lower the ramp by approximately 4.62° to meet safety regulations.

We have,

To determine the angle created by the bottom of the ramp and the ground, we can use the trigonometric function of sine.

In the given triangle, the height is 6 ft and the base is 16 ft.

The angle we want to find is opposite the height (let's call it θ).

The sine of an angle is defined as the ratio of the opposite side to the hypotenuse.

sin(θ) = opposite/hypotenuse

sin(θ) = 6/16

sin(θ) = 0.375

To find the angle θ, we can take the inverse sine (also known as arcsine) of 0.375:

θ = arcsin(0.375)

θ ≈ 22.62°

To meet safety regulations, the angle should be no more than 18°. Therefore, the contractor needs to lower the ramp by:

22.62° - 18° ≈ 4.62°

Thus,

The contractor should lower the ramp by approximately 4.62° to meet safety regulations.

Step-by-step explanation:

we require to set up 2 equations and solve simultaneously.

let a be the number of adults and c the number of children , then

a + c = 470 → (1) based on number of people

3a + c = 910 → (2) based on ticket sales

subtract (1) from (2) term by term to eliminate c

(3a - a) + (c - c) = 910 - 470

2a + 0 = 440

2a = 440 ( divide both sides by 2 )

a = 220

substitute a = 220 into (1) and solve for c

220 + c = 470 ( subtract 220 from both sides )

c = 250

844,758,200,030 will be rounded to the nearest billion. what is the rounding digit

Answers

844,758,200,030 will be rounded to 845 billion (845,000,000,000).

The rounding digit is 5.

How to find the rounding digit?

Estimation a is a method used for calculating the approximate value of a quantity (just to get a 'rough answer')

In estimation 1, 2,3, and 4 are rounded down while 5, 6, 7, 8 and 9 are rounded up.

To round 844,758,200,030 to the nearest billion, we look at the digit in the hundred millionths place, which is 7.

Since 7 is greater than or equal to 5, we round 844,758,200,030 up to 845,000,000,000. The rounding digit is therefore 5.

The area of triangle ABC is approximately 231.89 square inches.

To solve this problem, we'll use the properties of a triangle and trigonometric functions.

Let's go step by step.

Part A: Determine m ∠A.

To find the measure of angle A, we can use the Law of Cosines.

The Law of Cosines states that for a triangle with sides of lengths a, b, and c, and angle A opposite side a, we have the formula:

c² = a² + b² - 2ab × cos(A)

In this case, c = 60 inches, a = 60 inches, and b = 60√2 inches.

Plugging in these values into the Law of Cosines equation, we get:

(60)² = (60)² + (60√2)² - 2(60)(60√2) × cos(A)

Simplifying:

3600 = 3600 + 7200 - 7200√2 × cos(A)

Now, let's solve for cos(A):

7200√2 × cos(A) = 7200

cos(A) = 7200 / (7200√2)

cos(A) = 1 / √2

cos(A) = √2 / 2

To determine the angle A, we need to find the inverse cosine of (√2 / 2), which is 45 degrees.

Therefore, m ∠A is 45 degrees.

Part B: Explain how to use the unit circle to find the exact values of all six trigonometric functions evaluated at A.

To find the values of the trigonometric functions at angle A, which is 45 degrees or π/4 radians, we can use the unit circle.

The unit circle is a circle with a radius of 1 unit, centered at the origin (0, 0) in a coordinate plane.

At angle A = 45 degrees or π/4 radians, the coordinates of the point on the unit circle are (√2/2, √2/2).

Using these coordinates, we can find the exact values of the trigonometric functions as follows:

sin(A) = y-coordinate = √2/2

cos(A) = x-coordinate = √2/2

tan(A) = sin(A) / cos(A) = (√2/2) / (√2/2) = 1

csc(A) = 1 / sin(A) = 1 / (√2/2) = √2

sec(A) = 1 / cos(A) = 1 / (√2/2) = √2

cot(A) = 1 / tan(A) = 1 / 1 = 1

Part C: Calculate the area of triangle ABC.

To calculate the area of triangle ABC, we can use Heron's formula, which is based on the lengths of the triangle's sides.

Heron's formula states that for a triangle with side lengths a, b, and c, the area (A) can be calculated as:

A = √(s(s-a)(s-b)(s-c))

where s is the semiperimeter of the triangle, calculated as:

s = (a + b + c) / 2

In this case, a = 60 inches, b = 60√2 inches, and c = 60 inches.

Calculating the semiperimeter:

s = (60 + 60√2 + 60) / 2

s = (120 + 60√2) / 2

s = 60 + 30√2

Now, we can calculate the area using Heron's formula:

A = √((60 + 30√2)((60 + 30√2) - 60)((60 + 30√2) - (60√2))((60 + 30√2) - 60))

Simplifying:

A = √((60 + 30√2)(60)(30√2)(30))

A = √(1800(30√2))

A = √(54,000√2)

A = 231.89 square inches (rounded to the nearest hundredth)

Therefore, the area of triangle ABC is approximately 231.89 square inches.

through: (4, 3), slope = undefined

20 POINTS‼️‼️

Answers

Answer:

x = 4

Step-by-step explanation:

a line with an undefined slope is a vertical line with equation

x = c ( c is the value of the x- coordinates the line passes through )

the line passes through the point (4, - 3 ) with x- coordinate 4 , then

x = 4 is the equation of the line

note this equation cannot be expressed in slope- intercept form
