Step-by-step explanation:

Enclosing something with fencing is a perimeter thing.  Since we are dealing with a circle, we need the circumference instead, which is the same thing, different formula.

[tex]C=\pi d[/tex]

Filling in with the diameter of 287 m:

[tex]C=\pi (287)[/tex]  or you could just say that the circumference is

287π.  If you have to multiply in π, then the circumference is

901.18 m

Answer:

The answer to your question is 901.2 m

Step-by-step explanation:

Data

Perimeter = ?

diameter = 287 m

Process

1.- Calculate the radius of the garden

    radius = diameter/2

-Substitution

   radius = 287/2

-Result

   radius = 143.5 m

2.- Calculate the perimeter

Perimeter = 2πr

-Substitution

Perimeter = 2(3.14)(143.5)

-Simplification and result

Perimeter = 901.18 ≈ 901.2 m

Answer: the distance from one corner of the field to the other corner is 136 m

Step-by-step explanation:

The distance from one corner to the other corner is the diagonal and it

divides the field into two equal right angle triangles. The diagonal represents the hypotenuse of each right angle triangle. The length and width of the rectangle represents the adjacent and opposite sides of the right angle triangle. To determine the length of the diagonal, d, we would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side²

Therefore

d² = 110² + 80²

d² = 12100 + 6400 = 18500

d = √18500

d = 136 meters

The distance from one corner of the football field to the other corner (the diagonal) is approximately 136.08 meters.

To find the distance from one corner of the football field to the other corner (the diagonal), we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

In this case, the width of the football field is one side of the right triangle, the length of the football field is the other side, and the diagonal (the distance we want to find) is the hypotenuse.

According to the Pythagorean theorem:

[tex]\[ d^2 = w^2 + l^2 \][/tex]

[tex]\[ d^2 = 80^2 + 110^2 \][/tex]

[tex]\[ d^2 = 18500 \][/tex]

To find d, we take the square root of both sides:

[tex]\[ d = \sqrt{18500} \][/tex]

[tex]\[ d \approx 136.08 \][/tex]

Therefore, the distance from one corner of the football field to the other corner (the diagonal) is approximately 136.08 meters.

Answer:600

Step-by-step explanation:

There are 60 seconds in one minute so you would need to multiply 60 by 10

A car traveling at a steady speed of 10 m/s will cover a distance of 600 meters in one minute.

The distance covered by a car moving at a steady speed can be calculated from the simple physics formula for speed: speed = distance/time. In this case, the speed of the car is given as 10 m/s, and the time is given as 1 minute. However, time needs to be in the same units as the speed, so we need to convert minutes to seconds. As one minute is equal to 60 seconds, we can use this conversion. Now, to solve for distance, we rearrange the equation to look like: distance = speed * time. Substituting the given speed and time, we get: distance = 10 m/s * 60 s = 600 m. Therefore, a car traveling at a steady speed of 10 m/s will cover a distance of 600 meters in one minute.

Answer:

2/75

Step-by-step explanation:

6 of the 30 pens are green, so the probability of selecting a green pen is 6/30 = 1/5.

The pen is then replaced, so there are still 30 pens in the drawer.  4 of the pens are black, so the probability of selecting a black pen is 4/30 = 2/15.

The probability of both events is therefore 1/5 × 2/15 = 2/75.

Answer:

(- 2, 3 )

Step-by-step explanation:

Given the 2 equations

7x - 2y = - 20 → (1)

9x + 4y = - 6 → (2)

Multiplying (1) by 2 and adding to (2) will eliminate the term in y

14x - 4y = - 40 → (3)

Add (2) and (3) term by term to eliminate the term in y

23x = - 46 ( divide both sides by 23 )

x = - 2

Substitute x = - 2 into either of the 2 equations and evaluate for y

Substituting into (2)

9(- 2) + 4y = - 6

- 18 + 4y = - 6 ( add 18 to both sides )

4y = 12 ( divide both sides by 4 )

y = 3

Solution is (- 2, 3 )

The required solution of the given simultaneous equation is x = -2 and y = 3.

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

Here,
Given equations,
7x - 2y = -20 - - - - - (1)

9x + 4y = -6 - - - - - (2)

Multiply equation 1 with 2 and add both equations,
14x - 4y  + 9x + 4y = -40 - 6
23x = -46
x = -2

Now,
7(-2) - 2y = -20
-2y = -6
y = 3

Thus, the required solution of the given simultaneous equation is x = -2 and y = 3.

Answer:

Step-by-step explanation:

Roasted turkey in Ally's Eats = 75

Roasted turkey in Bob's goods  = 4 / 5 x  Ally's Eats

= (4 / 5) x 75

= 60

Roasted turkey in Charlotte's Market = N ( let )

Given

5/6  N  = 75

N = 6 / 5 x 75

= 90

Roasted turkey in Charlotte's Market  = 90 .

To find the average number of roasted turkeys owned by each of the three shops, add up the number of turkeys owned by all three shops and divide by the number of shops. In this case, the average is 75 turkeys.

To find the average number of roasted turkeys owned by each of the three shops, we need to calculate the total number of roasted turkeys owned by all three shops and then divide it by the number of shops.

First, we find the number of roasted turkeys owned by Bob's Goods, which is 4/5 * 75 = 60 turkeys.

Next, we find the number of roasted turkeys owned by Charlotte's Market, which is 75 / 5/6 = 90 turkeys.

Finally, we add up the number of turkeys owned by all three shops: 75 + 60 + 90 = 225 turkeys.

To find the average, we divide the total number of turkeys by the number of shops: 225 turkeys / 3 shops = 75 turkeys.

Therefore, the average number of roasted turkeys owned by each of the three shops is 75 turkeys.

Good lessons!

Final answer:

The correct equation that expresses how many days Meghan used her cell phone is 45n = 540. By dividing both sides by 45, we find that n = 12, indicating she used her cell phone for 12 days.

Explanation:

The question is asking to find the equation that represents the number of days Meghan used her cell phone, given that she used it for 45 minutes each day and the total usage was 540 minutes. To solve this, you would set up an equation where the number of days (n) times the daily usage (45 minutes) equals the total usage (540 minutes).

Therefore, the correct equation would be 45n = 540.

To find out how many days she used her cell phone, you would divide both sides of the equation by 45:

45n / 45 = 540 / 45

n = 12

This means Meghan used her cell phone for 12 days.

Answer: It should be g > 9

Step-by-step explanation:

-Solve:

[tex]g-3>6[/tex]

[tex]g-3+3>6+3[/tex]

[tex]g>9[/tex]

So, Therefore, the result is g > 9

The solution to the inequality is g > 9.

Here, we have,

To solve the inequality g - 3 > 6, we will isolate the variable g.

Adding 3 to both sides of the inequality, we get:

g - 3 + 3 > 6 + 3

Simplifying, we have:

g > 9

So, the solution to the inequality is g > 9.

To graph the solution on a number line, we represent all values of g that are greater than 9. We can denote this by shading the region to the right of 9 on the number line.

Here's a graphical representation:

    ------------------------>

    -8 -7 -6 -5 -4 -3 -2 -1  0  1  2  3  4  5  6  7  8  9 10 11 12 ...

                o

                |

                |

                |

In this representation, the open circle (o) indicates that 9 itself is not included in the solution since the inequality is strict (g > 9). The shaded region represents all values of g that are greater than 9.

Answers and Step-by-step explanations:

1. We need to plug in values of x into the functions f(x) and g(x):

f(2) = 2.5 * 2 - 10.5 = -5.5                         g(2) = [tex]64 * (0.5^2)[/tex] = 16

f(3) = 2.5 * 3 - 10.5 = -3                            g(3) = [tex]64 * (0.5^3)[/tex] = 8

f(4) = 2.5 * 4 - 10.5 = -0.5                         g(4) = [tex]64 * (0.5^4)[/tex] = 4

f(5) = 2.5 * 5 - 10.5 = 2                             g(5) = [tex]64 * (0.5^5)[/tex] = 2

f(6) = 2.5 * 6 - 10.5 = 4.5                          g(6) = [tex]64 * (0.5^6)[/tex] = 1

(a) Notice that at 14 on the x-axis, the blue line is above 4. Meanwhile, at 14, the red line is less than 2. Obviously, we can see that if the printed ad revenue was less than 2 and the online ad revenue was greater than 4, that's more than a double, so the lead marketing executive is correct.

(b) The approximate year that the revenues were equal is the place where the lines intersect. It's approximately at Year 7.5.

3.

(a) The Western Beach is clearly decreasing; it is decreasing by 2 ft per year. Meanwhile, the Dunes Beach is clearly increasing; it's increasing by 5 ft per year. (I'm not sure what kinds of "patterns" you're looking for).

(b) Year 11 and 12; this is because here, Western is going from 78 to 76 ft and Dunes is going from 75 to 80, so they'll likely coincide sometime in that time interval.

(c) One thing you can do is to create equations (of the form y = mx + b) for each of the beaches and then set those linear equations equal to each other.

Answer:

Page 1:

f(2) = -5.5

f(3) = -3

f(4) = -0.5

f(5) = 2

f(6) = 4.5

Notice the values are increasing by 2.5

g(2) = 16

g(3) = 8

g(4) = 4

g(5) = 2

g(6) = 1

Notice the values are getting divide by half

Page 2:

A:

At 14 years, the revenue for online ads are a little over 4 million dollars. However, for printed ads, the revenue is only about 1.5 million dollars.  If you double 1.5 million, you will only get 3 million. That is less than 4 million. So, the lead marketing executive was correct.

B:

The approximate year that the two revenues were equal was approximately 7 and a half (or 7.5).

Page 3:

A:

For the Western Beach, the width is decreasing by exactly 2 feet per year. For the Dunes Beach, the width is increasing by exactly 5 feet per year.

B:

The beaches will have the same width somewhere between years 11 and 12.

C:

A good way to get an even better approximation on when these beaches will have the same width, is to write them in slope-intercept form. The Western Beach equation will look like f(x) = -2x + 100 and the Dunes Beach equation will look like g(x) = 5x + 20.

Answer:

106.50

Step-by-step explanation:

just did it

Final answer:

To calculate the simple interest on a $400 necklace purchase with a 21.3% interest rate after 15 months, use the simple interest formula I = PRT, resulting in an interest of $106.50.

Explanation:

To calculate the simple interest added to a $400 necklace purchase with a credit card charging 21.3% simple interest after 15 months, you can use the formula for simple interest: I = PRT, where I is the interest, P is the principal amount (initial loan balance), R is the rate of interest per year, and T is the time in years. In this question, P = $400, R = 21.3% or 0.213, and T = 15/12 years (to convert months to years).

First, convert the interest rate to a decimal by dividing by 100:

R = 21.3% \/ 100 = 0.213

Next, convert the time from months to years:

T = 15 months \/ 12 = 1.25 years

Finally, calculate the simple interest:

I = P times R times T

I = $400 times 0.213 times 1.25

I = $106.50

Therefore, the interest added after 15 months would be $106.50.
