Answer:

A.  (4000/3)  π cubic units

Step-by-step explanation:

The volume of a sphere is given by V = (4/3) π r³

Since this sphere has a radius of 10, we can find its volume by inserting the value of the radius in the formula:

[tex]V = \frac{4}{3} \pi 10^{3} = \frac{4}{3} * 1000 * \pi =\frac{4000}{3} \pi[/tex]

Since all the possible answers are given with π in them, we can stop the calculation there and say the volume is (4000/3)  π cubic units.

Answer:

(4000/3)[tex]\pi[/tex] units³

25.50 = 7d + 2p

52.50 = 5d + 10p

These are the two equations we're going to use to determine the price of popcorn.

First we need to eliminate one set of variables. Let's eliminate the drinks.

127.50 = 35d + 10p

-367.50 = -35d + -70p

-240 = 0d - 60p

-240 = -60p

P = 4.00

So, popcorn is $4, right? Let's keep working on the problem so we can double check...

So, now let's add the $4 as the variable for P.

25.50 = 7d + 8

52.50 = 5d + 40

17.50 = 7d

12.5 = 5d

d = 2.5

d=2.5

This checks out! Since both equations state that drinks are 2.50, that means we have the right pricing for popcorn... $4.00

Popcorn is $4.00, drinks are $2.50

Answer:

I believe the answer is 110.

Answer:

Step-by-step explanation:

In this problem we need to use the Inscribed Angle theorem, which states that an inscribed angle is one-half its subtended arc.

[tex]\angle C=\frac{1}{2}arc(DB)=70\°[/tex]

Then, we use the theorem about a cyclic quadrilateral, which is an inscribed quadrilateral: "the opposite angles in a cyclic quadrilateral are supplementary".

[tex]\angle C + \angle A = 180\°\\\angle A = 180\° - \angle C\\\angle A = 180\° - 70\° \\\angle A = 110\°[/tex]

Therefore, the answer is 110°

Answer:

The answer is 11

Step-by-step explanation:

To solve the expression we must use order of operations following the memotecnic rule PEDMAS that states the order of operations. First solve parenthesis, then exponents, then divisions and multiplications from left to right and finally additions and subtractions from left to right . Following this rule we have:

30-2(7+2)-1

First parenthesis

30-2*(9)-1

There are no exponents. There are no divisions so we do multiplications first

30 -18 -1

There are no additions we only do the remaining subtractiosn form left to right

Using the points where the blue line crosses the X and Y axis:

(0,5) ans (-1, 0)

The slope is the change in Y over the change in X:

0-5 / -1 - 0 = -5/-1 = 5

Slope = 5

Y intercept = y1 = 5

Equation = y = 5x+5

Answer:

The correct equation for the trend line is y = 5x + 5

Step-by-step explanation:

* Lets revise the form of the equation of the line

- The slope intercept form is y = mx + b, where m is the slope of  

  the line and b is the y-intercept

- In the problem we have a trend line in the scatter-plot

- we cant find the exact value of the slope of the line from the points

 in the scatter-plot because the line is best fit to the point, then we

 will start with the y-intercept of the line

- From the graph the line intersect the y-axis at point (0 , 5)

∴ The y-intercept is 5

- We have two answers have y- intercept = 5, the first and second

 answer, the right answer is one of them

- From the graph try to find two points closed the the line and use

 them to find the slope of the line

- There are two points approximately closed to the line at points

  (0 , 5) and (-1 , 0)

- Lets use the rule of the slope of a line which passes through points

  (x1 , y1) and (x2 , y2)

- The slope of the line = (y2 - y1)/(x2 - x1)

∵ The point (0 , 5) is (x1 , y1) and point (-1 , 0) is (x2 , y2)

∵ x1 = 0 , x2 = -1 and y1 = 5 , y2 = 0

∴ the slope = (0 - 5)/-1 - 0 = -5/-1 = 5

∵ The equation of the line is y = mx + b

∵ m = 5 and b = 5

∴ The equation is y = 5x + 5

No, the answer is not reasonable. It should be about 10 pounds.

Step-by-step explanation:

Given,

The quantity of hot dog bought by Jill's club = [tex]4\frac{2}{5}[/tex] pounds,

Hot dog = [tex]3\frac{1}{2}[/tex] pounds

Hamburger = [tex]2\frac{3}{10}[/tex] pounds

So, the total quantity of meat they bought

[tex]=4\frac{2}{5}+3\frac{1}{2}+2\frac{3}{10}[/tex]

[tex]=\frac{22}{5}+\frac{7}{2}+\frac{23}{10}[/tex]

[tex]=\frac{44+35+23}{10}[/tex]  ( Adding fractions ),

[tex]=\frac{102}{10}[/tex]

[tex]=10.2\text{ pounds}[/tex]

Since, [tex]8\frac{1}{2}=\frac{17}{2}=8.5[/tex]

[tex]\implies 8.5\neq 10.2[/tex]

Answer:

B. 600,000 (1.15)^{n-1}

Step-by-step explanation:

The n-th term of a geometric sequence with initial value a and common ratio r can be determined by multiplying the first term of the sequence (i.e. initial value a) by r^{n-1}.

The first term (i.e. initial value a) is 600,000.

The common ratio r can be calculated by dividing any two consecutive terms in the sequence:

r = 690,000/600,000 = 1.15 or r = 793,500/690,000 = 1.15

Thus, we get the answer:

the explicit rule that can be used to determine the value of the art collection n years after that is 600,000 (1.15)^{n-1}

Step-by-step explanation:

Arc length is defined as:

s = rθ

where r is the radius and θ is the angle in radians

A unit circle has a radius of 1, so the arc length is equal to the radian measure of the angle.

The radian measure determines the arc length on the unit circle using the formula s = θ for a unit circle (radius = 1). Radians, being a ratio of arc length to radius, allow for direct conversion between angle and arc length, facilitating calculations and conversions between radians and degrees.

The radian measure of an angle can determine the arc length on the unit circle by using the formula arc length (s) = radius (r) × angle in radians (θ). Since the unit circle has a radius of 1, this simplifies to s = θ. The concept of radians is crucial here; a radian is defined as the ratio of the arc length to the radius of the circle, making it a dimensionless unit. This relationship remains constant regardless of the circle's size, meaning the radian measure directly gives the arc length on the unit circle.

For a full revolution of 2π radians (360 degrees), the arc length is equal to the circumference of the circle, which is 2πr. In the case of the unit circle, this equates to an arc length of 2π. This principle allows for the conversion between radians and degrees, and calculation of arc lengths for any given angle measured in radians.

Answer:

68

Step-by-step explanation:

The first differences of the given terms are ...

8 -5 = 3

11 -8 = 3

These are the same value, so we see this sequence is an arithmetic sequence with a common difference of 3. The first term is 5.

The explicit formula for the n-th term is ...

an = a1 +d(n -1)

We know a1=5, d=3, and we want to find the value for n=22. Hence ...

a22 = 5 +3(22 -1) = 5 +63 = 68

The 22nd term is 68.

Answer:

Question 1: x = 0,6,4

Step-by-step explanation:

#1. If we let x be the side of the cut-out square, the formula for the volume of the box is

[tex]\text{Volume} = (12 - 2x)(8 - 2x)(x).[/tex]

Expanding gives us

[tex]\text{Volume} = 4x^3 - 40x^2 + 96x. [/tex]

To find the zeros, we need to set the equation to 0, and the values of x that would result to zero would be:

[tex]x = 0, 6, 4[/tex]

As how it is told 'he' wanted to make a box with no lid for his marble connection, 'he' wants to cut out four "Identical" squares from all of the corners of the sheet (which I'm assuming is that there is four corners) and by doing so he then wants to fold all the sides...

So he buys one that is 8 by 12 inches, so you can draw a box that is (8, 12) put an 'x' at all four corners and 'cut' it the corners out.

Here's the formula that you can use... Which could be either one I guess..

-Cube = a 3

-- a is the side length

-Rectangular prism = a * b * c

-- a, b, c are the length, width, and height

The volume of a cube is side times side times side. Since each side of a square is the same, it can simply be the length of one side cubed. If a square has one side of 4 inches, the volume would be 4 inches times 4 inches times 4 inches, or 64 cubic inches.

Once you found a function I think you should use the quadratic equation, which is- y=x2-20x+96

And you could use that equation to graph it out... But if they want it to be the volume of 12 cubic inches then er-... Yeah that's were i'm stumped at... My apologies..

Answer:

138 cm³

Step-by-step explanation:

Given in the question that base of the rectangular prism = 36 cm²

Height of the prism = 3 5/6 cm = 23/6

We know that the volume of a rectangular prism with base area B and height H is given by

Plug values in the formula above to find the volume of the prism

Volume = 36(23/6)

              = 6(23)

              = 138 cm³

So the volume of prism = 138 cm³

Answer:

3.4

Step-by-step explanation:

Standard deviation of a population is defined as:

σ² = ∑(xᵢ − μ)² / n

The standard deviation of a sample is defined as:

s² = ∑(xᵢ − x)² / (n - 1)

It's not clear which one we have, so let's calculate both.

First, we must find the mean.

μ = (5+12+15+10+12+6+8+8) / 8

μ = 9.5

Now we find the squares of the differences:

(5-9.5)² + (12-9.5)² + (15-9.5)² + (10-9.5)² + (12-9.5)² + (6-9.5)² + (8-9.5)² + (8-9.5)²

= 80

Divide by n:

σ² = 80 / 8

σ² = 10

And take the square root:

σ = √10

σ ≈ 3.2

That's not one of the answers, so let's try the standard deviation of a sample instead of a population.

Instead of dividing by n, we'll divide by n-1:

s² = 80 / 7

And take the square root:

s = √(80/7)

s ≈ 3.4

So that must be it.

Answer:

Step-by-step explanation:

To calculate the theoretical probability here, we need three inputs:  1) the number of trials (which here is 7); the probability of success (which here is 0.75); and an integer representing the particular outcome (which here would be r:  {0, 1, 2, 3, 4, 5, 6, 7}.

(a)  Most of today's calculators have probability distribution functions built in.  I've used binompdf(n,p,r) here.  i. P(2) = 0.012 is correct; it's the result of typing in binompdf(7,0.75,2).  ii. P(3) = 0.058 is correct.  iii. P(4) = 0.005  is false; this probability is 0.173.  iv. P(5) = 0.015 is false.   v.  P(6) = 0.311 is correct.

(b) The probability that at least four trials are successful is equivalent to P(4) + P(5) + P(6) + P(7).   Another way in which to calculate this would be to add up P(0) + P(1) + P(2) + P(3) and subtract the resulting sum from 1.00:  That comes to:  1 - (0.000 + 0.001 + 0.012 + 0.058), or 1 - 0.071, or 0.929

Answer:

32 ft

Step-by-step explanation:

find the area of the large rectangle:

30 x 16 = 480

find the area of the small rectangle:

10 x 8 = 80

subract the small rectangle from the big rectangle to get the area of the shaded region:

480 - 80 = 400

now plug this area and the height into the equation for triangle area:

A = bh/2

400 = b(25)/2 multiply both sides by 2

2(400) = 2(25b/2)

800 = 25b divide both sides by 25

800/25 = 25b/25

32 = b

For this case we have that the area of the shaded region is given by the subtraction of the large rectangle minus the small rectangle.

[tex]A_ {sr} = 30 * 16-10 * 8\\A_ {sr} = 480-80\\A_ {sr} = 400[/tex]

Thus, the area of the shaded region is [tex]400 \ ft ^ 2[/tex]

If the triangle must have the same area and a height of 25, then we have:

[tex]400 = \frac {1} {2} b * 25\\400 = 12.5b[/tex]

Dividing between 12.5 on both sides of the equation:

[tex]b = 32[/tex]

Thus, the base of the triangle is 32.

- Congruent triangles have same areas and same perimeters

- Ex: If Δ ABC ≅ Δ XYZ, then their corresponding sides are congruent

 and their corresponding angles are equal

 side AB ≅ side XY , side BC ≅ side YZ , side AC ≅ side XZ

 angle A ≅ angle X , angle B ≅ angle Y , angle C ≅ angle Z

* Lets solve the problem

∵ Δ FGH ≅ Δ IJK

- The corresponding sides are:

# FG and IJ

# GH and JK

# FH and IK

∵ The corresponding side of GH is JK

∵ The corresponding sides are congruent

∴ GH ≅ JK

F + V = E + 2 ( subtract 2 from both sides )

F + V - 2 = E ← substitute values

20 + 12 - 2 = E, hence
