The circumference of a circle is 16 ft.
The radius is ?

Answers

Answer:

8/pi or approximately 2.55 ft

Step-by-step explanation:

The formula for the circumference is

C = 2 * pi *r

16 = 2 * pi *r

Divide each side by 2 pi

16 / ( 2 pi) = 2 * pi * r/ ( 2 pi)

8 / pi = r

Using 3.14 for pi

8 / 3.14 = r

2.54777 = r

2.55 =r

Answer:

Radius ≈ 2.55 ft.

Step-by-step explanation:

GIVEN :-

Circumference of circle = 16 ft.

TO FIND :-

Radius of the circle

FORMULAE TO KNOW BEFORE SOLVING :-

For a circle with radius 'r' & circumference 'c' ,

[tex]r = \frac{c}{2\pi }[/tex]

SOLUTION :-

Hi there! The correct answer should be: x is 60 degrees

Step-by-step explanation:

okay, so the equation is:

2x + 60 = 180

which we will solve:

2x + 60 - 60 = 180 - 60

2x = 120

x = 60

solve the system of equations using elimanation
-2x+2y=6
4x+2y=-5

Answers

Answer:

Your solution is (-11/6, 7/6).

Step-by-step explanation:

-2x + 2y = 6

4x + 2y = -5

Right away I can see that our y-values are the same. We want to eliminate one variable at a time, so let's make one of the 2y's a positive by multiplying each term in the equation by -1.

4x + 2y = -5

-1(4x + 2y = -5)

-4x - 2y = 5

Now we have a new equation in our system.

-2x + 2y = 6

-4x - 2y = 5

Now eliminate by performing each action given by the terms.

-2x + 2y = 6

-4x - 2y = 5

_________

-6x = 11

Divide both sides by -6.

x = 11/-6

Now that we know x, plug it back into one of the original equations to find y.

-2x + 2y = 6

-2(11/-6) + 2y = 6

Multiply.

-22/-6 + 2y = 6

22/6 + 2y = 6

Subtract 22/6 from both sides.

2y = 6 - 22/6

2y = 36/6 - 22/6

2y = 14/6

2y = 7/3

Divide both sides by 2.

y = (7/3)/2

y = 7/6

Your solution is (-11/6, 7/6).

Check your answer by plugging both values into one of the original equations.

4x + 2y = -5

4(-11/6) + 2(7/6) = -5

Multiply.

-44/6 + 14/6 = -5

Add.

-30/6 = -5

Divide.

-5 = -5

Your answer is correct.

The temperature in Sam's home varies sinusoidal over time. Given the equation T = 4 cos(30(t − 8)) + 16 describes the temperature of the house in degrees celsius in terms of the number of hours since 12 midnight.

Answers

Answer:

The temperature is: 14.5 degrees

Step-by-step explanation:

Given

[tex]T = 4 \cos(30(t - 8)) + 16[/tex]

Required

The temperature at 4:15

We have:

[tex]t = 4:15[/tex]

Convert to hours

[tex]t = 4+\frac{15}{60}[/tex]

[tex]t = 4+0.25[/tex]

[tex]t = 4.25[/tex]

So:

[tex]T = 4 \cos(30(t - 8)) + 16[/tex]

[tex]T = 4 \cos(30(4.25 - 8)) + 16[/tex]

[tex]T = 4 \cos(30(-3.75)) + 16[/tex]

Open bracket

[tex]T = 4 \cos(-112.5) + 16[/tex]

[tex]T = 4 *-0.3826 + 16[/tex]

[tex]T = -1.5304 + 16[/tex]

[tex]T = 14.4696[/tex]

Approximate

[tex]T = 14.5^o[/tex]

IQ scores are normally distributed with a mean of 100 and a standard deviation of 15. What is the probability that a randomly chosen person's IQ score will be between 101 and 134, to the nearest thousandth

Answers

Answer:

Step-by-step explanation:

IQ scores are normally distributed with a mean of 100 and a standard deviation of 15. What is the probability that a randomly chosen person's IQ score will be between 101 and 134, to the nearest thousandth

z = (x-μ)/σ, where x is the raw score,

μ is the population mean = 100

σ is the population standard deviation = 15

For x = 101

z = 101 - 100/15

z = 0.066667

Probability value from Z-Table:

P(x = 101) = 0.52658

For x = 134

z = 134 - 100/15

z = 2.26667

Probability value from Z-Table:

P(x= 134) = 0.98829

Therefore,

Determine whether the side lengths could represent a right triangle.

14, 21, 25

Answers

Answer:

No

Step-by-step explanation:

Using the given values, 25 is the largest value, so if this were a right triangle, it would be the hypotenuse.

Using Pythagoras' theorem: For this triangle to be a right triangle, √(21² + 14²) must be equal to 25.

√(21² + 14²) = 25.239 (5sf) ≠ 25

Hence the triangle formed is not right.

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem to find the hypotenuse

a^2 + b^2 = c^2  where a and b are the legs and c is the hypotenuse

6^2 + 7^2 = x^2

A contestant on a game show must choose 2 of 16 boxes. Once a box is chosen, it is removed from the game. Of the 16 boxes, 3 contain money, 5 contain traveling prizes, and 8 are empty. What is the probability that both boxes are empty?

Answers

Answer:

7 / 30

Step-by-step explanation:

This is a selection without replacement probability :

Total boxes = 16

With money = 3

With traveling prices = 5

Empty = 8

P(choosing 2 empty boxes) :

P(empty) * P(empty)

P(empty) = Number of empty boxes / total number of boxes

First pick = empty

P(empty) = 8 / 16 = 1/2

Without replacement :

Second pick = empty

P(empty) = 7 / 15

P(choosing 2 empty boxes) = 1/2 * 7/15 = 7 /30

A boat is traveling due North at 27mph. A current is flowing at a bearing of 60° west of south at 8mph. Find the actual speed and direction of the boat written in magnitude and direction form.

Answers

Answer: [tex]24.02\ mph[/tex]

Step-by-step explanation:

Given

Boat is traveling due to north at [tex]v_{bf}=27\ mph[/tex]

The current is flowing [tex]60^{\circ}[/tex] west of south at [tex]v_f=8\ mph[/tex]

Suppose the actual velocity of boat is [tex]\vec{v_b}[/tex]

In vector notation we can write

[tex]\Rightarrow \vec{v_{bf}}=\vec{v_b}-\vec{v_f}\\\\\Rightarrow \vec{v_b}=\vec{v_{bf}}+\vec{v_f}[/tex]

Flow of current can be written as

[tex]\Rightarrow \vec{v_f}=-8\sin 60^{\circ}\hat{i}-8\cos 60^{\circ}\hat{j}[/tex]

Insert the values of vectors

[tex]\Rightarrow \vec{v_b}=27\hat{j}-8\sin 60^{\circ}\hat{i}-8\cos 60^{\circ}\hat{j}\\\\\Rightarrow \vec{v_b}=-4\sqrt{3}\hat{i}+27\hat{j}-4\hat{j}\\\\\Rightarrow \vec{v_b}=-4\sqrt{3}\hat{i}+23\hat{j}[/tex]

Magnitude of the velocity is

[tex]=\sqrt{(4\sqrt{3})^2+(23)^2}\\=\sqrt{48+529}\\=24.02\ mph[/tex]

The actual direction and magnitude of the velocity of the boat is the sum of

the velocity of the boat and the velocity of the current both in vector form.

The actual velocity and direction of the boat are approximately 24.02 m/s at a bearing of 16.76° west of north.

Reasons:

Direction of the boat = North

Speed of the both = 27 mph

Direction of the current = 60° west of south

Speed of the current = 8 mph

Required:

The actual speed and direction of the boat written in magnitude and

direction.

Solution:

The velocities given in vector form are;

Velocity of the boat, [tex]\vec {v}_{boat}[/tex] = 27·j

60° west of south = 30° south of west

Therefore;

Velocity of the current, [tex]\vec{v}_{current}[/tex] = -8 × cos(30°)·i - 8×sin(30°)·j

The actual velocity of the boat, [tex]\vec{v}_{actual}[/tex] = [tex]\mathbf{\vec {v}_{boat}}[/tex] + [tex]\mathbf{\vec{v}_{current}}[/tex]

Which gives;

[tex]\vec{v}_{actual}[/tex] = 27·j - 8 × cos(30°)·i - 8 × sin(30°)·j

[tex]\vec{v}_{actual}[/tex] = 23·j - (4·√3)·i

Therefore;

[tex]\vec{v} _{actual}[/tex] = -(4·√3)·i + 23·j

Which gives;

[tex]|v_{actual}|[/tex] = √((-4·√3)² + 23²) = √(577) ≈ 24.02

The magnitude of the velocity of the boat, [tex]\mathbf{|v_{actual}|}[/tex] ≈ 24.02 m/s

The actual direction of the boat, θ, is given by the arctangent of the ratio

of the vertical to the horizontal component of the velocity as follows;

[tex]\displaystyle \theta = arctan \left(\frac{23}{-4 \cdot \sqrt{3} } \right) \approx \mathbf{-73.24^{\circ}}[/tex]

Based on the horizontal and vertical component, the above angle θ is

approximately 73.24° relative to the negative x-axis, which is 90° - 73.24° =

16.76° west of north.

Therefore;

The actual direction of the both is on a bearing of approximately 16.76° west of north.

This family was situated in the Notch . . . .D. Up the chimney roared . . . .Passage: "The Ambitious Guest" by Nathaniel HawthorneNathaniel Hawthorne lived and wrote in the puritanical culture of 19th century New England. In the decade after he completed college, he spent most of his time in solitude writing his early short stories and a novel. When he was unable to support himself by writing, he tried several careers, but continued to write novels and short stories. Although he visited England and Italy, his best-known stories describe the gloom and loneliness of life in New England. He died in 1864.One September night a family had gathered round their hearth, and piled it high with the driftwood of mountain streams, the dry cones of the pine, and the splintered ruins of great trees that had come crashing down the precipice. Up the chimney roared the fire, and brightened the room with its broad blaze. The faces of the father and mother had a sober gladness; the children laughed; the eldest daughter was the image of Happiness at seventeen; and the aged grandmother, who sat knitting in the warmest place, was the image of Happiness grown old. They had found the "herb, heart's-ease," in the bleakest spot of all New England. This family was situated in the Notch of the White Hills, where the wind was sharp throughout the year, and pitilessly cold in the winter, giving their cottage all its fresh inclemency before it descended on the valley of the Saco. They dwelt in a cold spot and a dangerous one; for a mountain towered above their heads, so steep, that the stones would often rumble down its sides and startle them at midnight.The daughter had just uttered some simple jest that filled them all with mirth, when the wind came through the Notch and seemed to pause before their cottagerattling the door, with a sound of wailing and lamentation, before it passed into the valley.The family were glad again when they perceived that the latch was lifted by some traveller, whose footsteps had been unheard amid the dreary blast which heralded his approach, and wailed as he was entering, and went moaning away from the door.The door was opened by a young man. His face at first wore the melancholy expression, almost despondency, of one who travels a wild and bleak road, at nightfall and alone, but soon brightened up when he saw the kindly warmth of his reception. He felt his heart spring forward to meet them all, from the old woman, who wiped a chair with her apron, to the little child that held out its arms to him. One glance and smile laced the stranger on a footing of innocent familiarity with the eldest daughter."Ah, this fire is the right thing!" cried he; "especially when there is such a pleasant circle round it. I am quite benumbed; for the Notch is just like the pipe of a great pair of bellows; it has blown a terrible blast in my face all the way from Bartlett." Denise collects stuffed animals.
