Answer 1

The arc length is a quarter of the circumference of the full circle, so 2πr/4.

The straight sides are both radii, so each length r.

Total perimeter

p = 2πr/4 + r + r = r(π/2 + 2)

We put in r=2, π=3.14 and get

p = (2(3.14/2 + 2)) = 3.14 + 4 = 7.14

Answer: 7.14 km

Answer 2

The perimeter is also known as the circumference. The formula for the circumference is C = pi x diameter.

Step 1) Find the diameter

d = r x 2

d = 2 x 2 = 4 km

Step 2) Find the whole circumference

C = pi x 4

C = 4pi km

Step 3) Find 1/4 of the circumference

4pi x 1/4 = 1pi

1pi = 3.14

Step 4) Add the sides not part of the arc

3.14 + 2 + 2 = 7.14

C = 7.14 km

Hope this helps! :)

Gia is running for school president. Her best friend designed a rectangular button that measures 2.5 inches by 2 inches. Gina liked the button so much she produced a campaign poster, which measures 5 feet by 4 feet. What scale factor did Gina use to make the poster from the button?

Answers

Answer:

24:1

Step-by-step explanation:

To find the scale used to make the poster we just need to find the ratio between the poster and the button, and we do this by dividing the length and width of the poster by the length and width of the button.

So, we have that:

ratio = length poster / length button = 5 feet / 2.5 inches = 2 feet to 1 inch

ratio = width poster / width button = 4 feet / 2 inches = 2 feet to 1 inch

if 1 foot is equal 12 inches, we have a ratio of 2*12 inches to 1 inch = 24 to 1 (24:1)

Write the equation x2=7x in standard form.

Answers

Answer:

i believe it's x2-7x=0

Step-by-step explanation:

Final answer:

To write the equation x^2 = 7x in standard form, subtract 7x from both sides and rearrange the terms in descending order of exponents.

Explanation:

The equation x^2 = 7x is a quadratic equation. To write it in standard form, we need to move all the terms to one side and set the equation equal to zero.

Subtracting 7x from both sides, we get x^2 - 7x = 0.

Next, we rearrange the terms in descending order of exponents: x^2 - 7x = 0.

How many seconds will it take the object to reach the ground?

Answers

Final answer:

It will take approximately 5.05 seconds for the object to reach the ground.

Explanation:

In order to determine how long it will take an object to reach the ground, we need to consider the height from which the object is dropped. Let's assume the height is 75.0 m.

The time it takes for an object to fall to the ground can be calculated using the equation t = sqrt(2h/g), where t is the time, h is the height, and g is the acceleration due to gravity (approximately 9.8 m/s^2).

Plugging in the values, t = sqrt(2 * 75.0 / 9.8) = sqrt(150 / 9.8) ≈ 5.05 seconds.

Therefore, it will take approximately 5.05 seconds for the object to reach the ground.

What is the equation of the line that passes through the point (-6,-6)(−6,−6) and has a slope of 2/3?

Answers

Answer:

y = 2/3 x -2

Step-by-step explanation:

We have a point and a slope

y = mx+b

The slope, m, = 2/3

y = 2/3 x+ b

The point is (-6,-6)

Substitute this into the equation to solve for b

-6 = 2/3 (-6) +b

-6 = -4+b

Add 4 to each side

-6+4 = -4+4+b

-2 =b

Substitute into the equation

y = 2/3 x+ b

y = 2/3 x -2

The equation of the line that passes through the point (-6, -6) is “y = 2/3x - 2”.

Which statement is correct about the system of linear equations graphed below? On a coordinate plane, a line with negative slope goes through (0, 3) and (4, 2). A line with positive slope goes through (0, negative 4) and (4, negative 2). The system of equations has one solution because the lines will eventually intersect. The system of equations has one solution because the lines will never intersect. The system of equations does not have one solution because the lines will eventually intersect. The system of equations does not have one solution because the lines will never intersect.

Answers

Answer:

the answer is A. The system of equations has one solution because the lines will eventually intersect

Step-by-step explanation: because as the line goes on it will intercect once and if it has only one point of intercect its one solution

The system of equations has one solution because the lines will eventually intersect.

Which statement is true?

We know that for a system of equations, the solutions are the points where the graphs of the equations do intercept.

Also, remember that two lines always intercept if they have different slopes (parallel lines have the same slope and different y-intercept).

In this particular case, we know that one line has a negative slope and the other has a positive slope, so the lines are not parallel. This means that the lines will intercept, so the system has one solution.

With that in mind, the correct statement is "The system of equations has one solution because the lines will eventually intersect."

1320:100 = 13.2

The possible number of students in the class who read a book last month is 13 students

Let the total number of students that read the book last month be x

If over 44% of the 30 students in a class read a book last month, hence;

44% of 30 = x

0.44 * 30 = x

1/2x went to April, so 1/2x remains.

1/2(1/2x) = 1/4x went to Jed, so 1/2x -1/4x = 1/4x remains.

1/2(1/4x) = 1/8x went to charity, so 1/4x -1/8x = 1/8x remains.

That remaining 1/8x was $30,000, so the total amount of Mr. Sanford's fortune was ...
