a sphere is inscribed in a cube with a volume of 125 cubic inches what is the volume of the sphere

Answers

Answer 1

Answer:

using [tex]\pi[/tex]:   65.45 in³ (nearest hundredth)

using [tex]\pi =3.14[/tex]:   65.42 in³ (nearest hundredth)

Step-by-step explanation:

The radius of the sphere is half the side length of the cube (see attached diagram).  Therefore, the side length of the cube = 2r

Given:

volume of the cube = 125 in³side length of cube = 2r

[tex]\textsf{Volume of a cube}=x^3\quad \textsf{(where}\:x\:\textsf{is the side length)}[/tex]

[tex]\implies 125=(2r)^3[/tex]

[tex]\implies \sqrt[3]{125}=2r[/tex]

[tex]\implies 5=2r[/tex]

[tex]\implies r=\dfrac52[/tex]

Substitute the found value of r into the volume of a sphere equation:

[tex]\begin{aligned}\textsf{Volume of a sphere} & =\dfrac43 \pi r^3\\\\ & =\dfrac43 \pi \left(\dfrac52\right)^3\\\\ & =\dfrac43 \pi \left(\dfrac{125}{8}\right)\\\\ & =\dfrac{500}{24} \pi\\\\ & =\dfrac{125}{6} \pi\\\\ & =65.45\:\sf in^3\:(nearest\:hundredth) \end{aligned}[/tex]

write an inequality for this situation
Embiid scored at least 31 points
A, E > 31
B, E < 31

Answers

Answer:  [tex]E \ge 31[/tex]

Reason:

"at least 31 points" means "31 or more".

So either E = 31 or E > 31 (meaning Embiid scored 31 points or he scored more than 31 points).

Choice A looks like the closest match assuming the inequality sign is [tex]\ge[/tex]

Saying E > 31 instead of [tex]E \ge 31[/tex] would be false because it leaves out the case E = 31.

Answers

Answer:

x = 14

Step-by-step explanation:

Knowing that this figure is a vertical angle.

Define vertical angles ⇒ a pair of opposite angles formed by intersecting lines

Thus, if the left side = 122

then the other side must equal 122

The equation is:

8x + 10 = 122

Subtract 10 from both sides

8x + 10 - 10 = 122 -10

8x = 122

Divide both sides by the same factor

8x/8 = 122/8

Simplify

x = 14

Thus, x = 14.

A table of values for the quadratic function f is shown below. If 3 is one solution to f(x) = 0, what is the value of the other solution?
Record your answer and fill in the bubbles on your answer document.

Answers

Answer:The answer to this oroblem would be -7

Step-by-step explanation:We can see this by when f(x) is 0 right next to it is -7

The value of the other solution for f(x)=0 is -7. This is obtained by taking the general form of the quadratic equation f(x)=y.

Quadratic function:A function is represented by an equation f(x)=ax²+bx+c where a≠0 and b, c are any real numbers.This can be generalized into f(x)=y where x is an independent variable and y is a dependent variable.

Given data:

In the table, x values range from -8 to 1

So, we can write using the general form f(x)=y for these values

For x=-8, f(-8)=-2.75

x=-7, f(-7)=0

x=-6, f(-6)=2.25

x=-5, f(-5)=4

x=-4, f(-4)=5.25

x=-3, f(-3)=6

x=-2, f(-2)=6.25

x=-1, f(-1)=6

x=0, f(0)=5.25

x=1, f(1)=4

And 3 is one of the solution to f(x)=0.

Calculating solution for f(x)=0:

It is given that f(x)=0 when x=3

Thus,

f(3)=0

From the table,

f(-7)=0

So, the other solution for the function f(x)=0 is -7.

George's living room is a square that is 33 ft long on each side. He knows the diagonal of the ceiling from corner to corner must be longer than 33 ft.

(a) He thinks that because a square cut in half forms a special right triangle with the diagonal as the hypotense, so he multiples the side length by two to get 66 feet.
What is George's mistake?

(b) What is the correct length of the diagonal of George's ceiling using the correct special right triangle shortcut? (give exact answer, do not round)

(c) Use either the pythagorean theorem OR the correct trigonometry ratios to solve for the length of the diagonal (round to the nearest tenth of a foot)

Answers

Answer:

47

Step-by-step explanation:

a)

a^2 + b^2 = c^2

33^2+33^2=c^2

2178=c^2

c=(nearest is 47)

b)

If you cut the square in half diagonally, it forms two right triangles with angle measures 90-45-45. You can use sin (opposite over hypotenuse) to find the length of the hypotenuse.  sin (45) would be 33/(hypotenuse length). From a trig chart, you can find that sin (45) is 1/sqrt(2), meaning that 33/x = 1/sqrt(2). This means that x=33sqrt(2), which is around 47.

Here,   [tex]x_i; \: \: i = 1,2, ... ,[/tex] n is its n data values and [tex]f(x_i)[/tex]is the probability of  [tex]X = x_i[/tex]

How to find that a given condition can be modeled by binomial distribution?

Binomial distributions consists of n independent Bernoulli trials. Bernoulli trials are those trials which end up randomly either on success (with probability p) or on failures( with probability 1- p = q (say))

Suppose we have random variable X pertaining binomial distribution with parameters n and p, then it is written as

[tex]X \sim B(n,p)[/tex]

The probability that out of n trials, there'd be x successes is given by

[tex]P(X =x) = \: ^nC_xp^x(1-p)^{n-x}[/tex]

The expected value and variance of X are:

[tex]E(X) = np\\ Var(X) = np(1-p)[/tex]

Put the values as 5 trials for each time 4 appears.

[tex]P(X =0) = \: ^5C_1(\dfrac{1}{6})^0(1-\dfrac{1}{6})^{5-0}=0.4018 \:\\P(X =1) = \: ^5C_1(\dfrac{1}{6})^1(1-\dfrac{1}{6})^{5-1}=0.402\\P(X =2) = \: ^5C_2(\dfrac{1}{6})^2(1-\dfrac{1}{6})^{5-2}=0.162\\P(X =3) = \: ^5C_3(\dfrac{1}{6})^3(1-\dfrac{1}{6})^{5-3}=0.032\\P(X =4) = \: ^5C_4(\dfrac{1}{6})^4(1-\dfrac{1}{6})^{5-4}=0.0032\\P(X =5) = \: ^5C_5(\dfrac{1}{6})^5(1-\dfrac{1}{6})^{5-5}=0.00013\\[/tex]

The probability of loosing $5 equal probability of 0 success.

[tex]P(Y=-5)=P(x=0)[/tex]

Similarly, for probability of getting profit are,

[tex]P(Y=2)=P(x=1)\\P(Y=4)=P(x=2)\\P(Y=6)=P(x=3)\\P(Y=8)=P(x=4)\\P(Y=1000)=P(x=5)[/tex]

Expected value of game,

[tex]E(Y)=\sum y .P(Y=y)\\E(Y)=-5.P(X=0)+2.P(X=1)+4.P(X=2)+6.P(X=3)+8.P(X=4)+1000.P(X=5)\\E(Y)=-0.2094[/tex]

Thus, the expected value of the game in which 5 dice (6-sided) are rolled simultaneously is -0.2094.

Find the missing dimension of the triangle.
Area = 30 mm squared
6 mm = height
b = mm

Answers

Answer:

b = 10 mm

Step-by-step explanation:

the area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex]bh ( b is the base and h the height )

given A = 30 and h = 6 , then

[tex]\frac{1}{2}[/tex]b × 6 = 30 , that is

3b = 30 ( divide both sides by 3 )

b = 10

Two angles are supplementary. The larger angle is
150

larger than the smaller angle. Find the measure of both angles, and separate your answers with a comma.

Answers

Answer:

x = 165, y = 15

Step-by-step explanation:

1. Well, what does supplementary mean? - The angles add up to 180°.

2. Let's form an equation: x + y = 180°

3. Let's say x is the larger angle and y is the smaller angle.

4. Let's form another equation: x = 150 + y

5. Put the two equations next to each other:

x + y = 180

x = 150 + y

6. We know what x is equaled to, so let's plug it into the first equation!

150 + y + y = 180

150 + 2y = 180

-150           -150

2y = 30

y = 15

7. Now, we know what y is, let's find x!

x + 15 = 180

   -15     -15

x = 165

The measure of both angles are  15 degrees and 165 degrees.

What is Angle?

An angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle

Given that the two angles are supplementary.

we know that supplementary angles are the angles whose sum is added to 180 degrees.

Let the smaller angle is x.

The larger angle is 150∘ larger than the smaller angle.

y=x+150

Now add both the angles which makes 180 degrees

x+x+150=180

2x+150=180

Subtract 150 on both sides

2x=30

Divide both sides by 2

x=15

So the smaller angle is 15 and the larger angle is 165 degrees

Hence,  the measure of both angles are  15 degrees and 165 degrees.
