The diameter of a circle is 6 ft. Find its circumference in terms of \piπ.

Answers

Answer 1

The circumference of circle with diameter 6 feet will be 6π feet.

According to the question,

We have the following information:

Diameter of the circle = 6 feet

Now, we will find the radius of the circle. We know that the radius of the circle is half that of its diameter.

Radius of the circle = Diameter/2

Radius of the circle = 6/2 feet

Radius of the circle = 3 feet

We know that the following formula is used to find the circumference of the circle:

Circumference of the circle = 2πr

Circumference of the circle = 2π*3

Circumference of the circle = 6π feet

Hence, the circumference of the circle is 6π feet.

Jan 10, 7:17:08 PM Which equation represents a line which is perpendicular to the line x - 2y = -14? Oy= -27 -1 Oy= 2x + 8 Submit Answer Oy=x+4 Oy = -x + 2

Answers

You need to determine which line is perpendicular to the line

[tex]x-2y=-14[/tex]

For two lines to be considered perpendicular their slopes must be the inverse positive, that is, if, for example, you have the lines

[tex]y_1=mx_1+b[/tex][tex]y_2=nx_2+c[/tex]

For them to be perpendicular one slope must be the inverse negative of the other such as

[tex]n=-\frac{1}{m}[/tex]

The first step is to write the given line in slope-intercept form:

1) Pass the x term to the right side of the equal sign

[tex]\begin{gathered} x-2y=-14 \\ x-x-2y=-14-x \\ -2y=-x-14 \end{gathered}[/tex]

2) Divide both sides of the expression by "-2"

[tex]\begin{gathered} -\frac{2y}{-2}=-\frac{x}{-2}-\frac{14}{-2} \\ y=\frac{1}{2}x+7 \end{gathered}[/tex]

The slope of the line is

[tex]m=\frac{1}{2}[/tex]

So the slope of a line perpendicular to it will be the inverse negative of it

[tex]\begin{gathered} n=-(\frac{1}{\frac{1}{2}}) \\ n=-2 \\ \end{gathered}[/tex]

The correct option is the one that has slope -2

Divide both sides by 3

[tex]\begin{gathered} \frac{-3}{3}x<\frac{6}{3} \\ -x<2 \end{gathered}[/tex]

Finally, multiply both sides by -1:

[tex]\begin{gathered} (-1)(-x)<2(-1) \\ x>-2 \end{gathered}[/tex]

Hence, x can take any value greater than -2.

So, the solutions that apply are 0 and 3.

Seventh grade > X.9 Reflections over the x- and y-axes: find the coordinates TF8 You have prizes to reveal The point D(-5, -3) is reflected over the y-axis. What are the coordinates of the resulting point, D'?

Answers

Answer

The coordinates of the resulting point, D' = (5, -3)

Explanation

When a given point with coordinates A (x, y) is reflected over the y-axis, the y-coordinate remains the same and the x-coordinate takes up a negative in front of it. That is, A (x, y) changes after being reflected across the y-axis in this way

A (x, y) = A' (-x, y)

So, for this question where the coordinate is D (-5, -3). it changes in the manner,

D (-5, -3) = D' (-(-5), -3) = D' (5, -3)

Slope of QR = 4/7; Slope of ST = 4/7, therefore, the lines are parallel to each other.

How to Determine if Two Lines are Parallel or Perpendicular?

To determine if two given lines are perpendicular to each other or parallel to each other, find their slopes.

Slope, m = change in y / change in x.

If they have the same slope, m, then they are parallel lines. If they have slopes that are negative reciprocal to each other, then they are perpendicular lines.

Given:

Q(9, 10)

R(-5, 2)

T(-1, 2)

Find the slope of QR and ST:

Slope of QR = (10 - 2)/(9 -(-5)) = 8/14 = 4/7

Slope of ST = (-2 - 2)/(-8 -(-1)) = -4/-7 = 4/7

The slope are the same, therefore they are parallel to each other.

An earthquake simply means a rapid motion of the solid layer of the Earth.

In this case, Nathan told his brother that up until a 7.8-magnitude earthquake hit Nepal in 2015, Mount Everest had been moving northeast at a rate of 7.7×10^-6 centimeters per minute.

Mario constructs a scale model of a building with a rectangular base. His model is 4.2 inches in length and 2 inches in width. The scale of the model is 1 inch = 15 feet What is the actual area, in square feet, of the base of the building?

Answers

First let's use two rules of three to determine the actual dimensions of the building.

For the length, we have:

[tex]\begin{gathered} 1\text{ inch}\to15\text{ feet} \\ 4.2\text{ inches}\to x\text{ feet} \\ \\ \frac{1}{4.2}=\frac{15}{x} \\ x=15\cdot4.2=63 \end{gathered}[/tex]

For the width:

[tex]\begin{gathered} 1\text{ inch}\to15\text{ feet} \\ 2\text{ inches}\to x\text{ feet} \\ \\ \frac{1}{2}=\frac{15}{x} \\ x=15\cdot2=30 \end{gathered}[/tex]

Now, calculating the area of the building base, we have:

[tex]\text{Area}=63\cdot30=1890\text{ ft2}[/tex]

So the area of the building base is 1890 ft².

In a middle school with 300 students, there are 40% boys, 1/3 of the students wear glasses, and 15% of the girls wear glasses. What is the probability (= how many percent is it) that a randomly selected student does not wears glasses? (Round the percentage to the nearest hundredth) *

Answers

We know that

• There are 300 students.

,

• 40% are boys (this means 60% are girls).

,

• 1/3 of the students wear glasses.

If 1/3 of the students wear glasses, then 2/3 of the students don't wear glasses. Let's find 2/3 of 300.

[tex]\frac{2}{3}\cdot300=\frac{600}{3}=200[/tex]

Therefore, 200 students don't wear glasses.

Then, we divide to find the probability.

[tex]P=\frac{200}{300}=0.6667[/tex]

Then, we multiply by 100.

[tex]0.6667\cdot100=66.67[/tex]Therefore, the probability is 66.67%.

A focus group of 12 people is to be chosen randomly from among 24 right-handed people and 5 left-handed people. In order to find the probability that 3 of the people chosen are right-handed, you should use

Answers

Let 1 and 2 mean that a person is right-handed or left-handed, respectively.

Consider the probability space as the different groups of 12 people that can be formed with the 29 total people. {(1,1,1,1,1,...1),(2,1,1,1,1,...,1),...}

We need to use the binomial distribution in order to find the answer.

Consider X to be the number of right-handed people in the group.

The probability of X=3 is then:

[tex]Pr(X=3)=\text{ binomial coefficien(}12,3\text{)}(\frac{24}{29})^3(1-\frac{24}{29})^{12-3}[/tex]

We used the formula

[tex]\begin{gathered} Pr(X=k)=\text{ binomial coefficient(n,k)}\cdot p^k(1-p)^{n-k} \\ \text{where } \\ k=3 \\ n=12 \\ p=\frac{24}{29} \end{gathered}[/tex]

Finally, we need to simplify the expression, as shown below

[tex]\Rightarrow P(X=3)=220(\frac{24}{29})^3(\frac{5}{29})^9=0.0000167[/tex]

This is the answer one obtains using the binomial distribution; nevertheless, the actual probability is equal to zero because it is not possible to form a group of 12 people that only contains 3 right-handed people as there are only 5 left-handed people (3+5=8).

If the triangle in the figure has a hypotenuse equal to 40 units, then the approximate length of x is 30.64 units

The length of the hypotenuse = 40 units

The angle = 50 degrees

Here we have to apply the trigonometric function

we know

sin θ = Opposite side / Hypotenuse

cos θ = Adjacent side / Hypotenuse

tan θ = Opposite side / Adjacent side

Here we have to use the equation of sin θ

Substitute the values in the equation

sin 50 = x/40

x = 40×sin 50

x = 30.64 units

Hence, if the triangle in the figure has a hypotenuse equal to 40 units, then the approximate length of x is 30.64 units

Given

To solve this equation for both possible values of x, you have to separate it into two calculations.

1) One will be for the case that the values inside the absolute term are multiplied by "+1":

[tex]\begin{gathered} 1\cdot(5-6x)-12=0 \\ 5-6x-12=0 \\ -6x+5-12=0 \\ -6x-7=0 \\ -6x=7 \\ -\frac{6x}{-6}=\frac{7}{-6} \\ x=-\frac{7}{6} \end{gathered}[/tex]

The first value of x is -7/6

2) The second will be the case that the absolute values are negative, that is as if they are multiplied by -1

[tex]\begin{gathered} (-1)(5-6x)-12=0 \\ -5+6x-12=0 \\ 6x-5-12=0 \\ 6x-17=0 \\ 6x=17 \\ \frac{6x}{6}=\frac{17}{6} \\ x=\frac{17}{6} \end{gathered}[/tex]

add equation 2a from 1:

5x - 5x -4y -25y + 2z + 30z = 21 - 120

add equation 1 and 3a

5x - 5x - 4y - 20y + 2z +25z = 21 - 105

0 - 768x + 783x = -60

15x = -60

x = -60/15

x = -4

substitute for x in equation 4a:

696y - 768(-4) = 2376

696y + 3072 = 2376

696y = 2376 -3072

696y = -696

y = -696/696

y = -1

substitute for y in equation 4:
