  (b) (125/6)π m³

Step-by-step explanation:

The formula for the volume of a sphere is ...

  V = (4/3)πr³ . . . radius r

The radius is half the diameter, so is (5/2) m. Then the volume is ...

  V = (4/3)π(5/2 m)³ = (4/3)(125/8)π m³ = (125/6)π m³

The median of the data is 5.5.

Since the sequence is 9,7,2,4,3,5,9,6,8,0,3,8

We have to arrange the above sequence in the smaller to largerst number

i.e.

0,2,3,3,4,5,6,7,8,8,9,9

So since 5 and 6 are in middle

So, the median is

Explanation:

1. Quantiy R

Decay model:

       [tex]\dfrac{dR}{dt}=-0.05R[/tex]

That is a first order reaction, whose solution is:

        [tex]R=R_0e^{-0.05t}[/tex]

The value at t = 0, R(0) = 100 is R₀.

Thus, the law is:

        [tex]R(t)=100e^{-0.05t}[/tex]

2. Quantity S

Decay model:

       [tex]\dfrac{dS}{dt}=-4[/tex]

That is a zero order kinetic, whose solution is:

       [tex]S=S_0-4t[/tex]

The value at t = 0, S(0) = 125 is S₀

Thus, the law is:

      [tex]S(t)=125-4t[/tex]

3. At what time will there ve equal quantities of both substances?

You must solve the system doing R(t) = S(t)

      [tex]100e^{-0.05t}=125-4t[/tex]

That equation must be solved by graphing or by consecutive iterations

Note that when t = 0 R(t) = 100 and S(t) = 125. From, that the quantities decreases.

Subsitute with t = 10.

Then, the time is greater than 10.

Substitute with t = 15

t = 20

t = 25

t = 24

Hence, 24 seconds is a satisfactory solution.

The graph attached shows that the intersection point is at t ≈ 23.548 seconds, confirming that 24 seconds is the best solution rounded to an integer number.

At t= 24 , in seconds, will there be equal quantities of both substances.

Given that,

The quantity R, in grams, of a certain radioactive substance decreases, according to the exponential decay model dR\dt=−0.05R, Where t is measured in seconds

The rate of decay of a second substance with the quantity S, in grams, can be represented by a linear model dS\dt=−4,

Where t is measured in seconds. If at time t=0, R(0)=100 and S(0)=125.

We have to determine,

At what time t, in seconds, will there be equal quantities of both substances.

According to the question,

Exponential decay model,

[tex]\dfrac{dR}{dt} = 0.05R[/tex]

The solution of first order reaction,

[tex]R = R_o.e^{0.05t}[/tex]

Substitute the value t = 0 ,R(0)= 100,

Then,

[tex]R(t) = 100.e^{0.05t}[/tex]

The decay model,

[tex]\frac{dS}{dt} = -4[/tex]

That is a zero order kinetic, whose solution is:

[tex]S= S_0-4t[/tex]

The value at t = 0, S(0) = 125 is S₀,

Therefore,

[tex]S(t) = 125-4t[/tex]

At what time will there +ve equal quantities of both substances,

Solve the system doing R(t) = S(t),

[tex]100.e^{-0.05t} = 125-4t[/tex]

The equation must be solved by graphing or by consecutive iterations

When t = 0 R(t) = 100 and S(t) = 125. From, that the quantities decreases.

Substitute with t = 10.

The left-hand side yields: 61 and the right-hand side yields 85.

Then, the time is greater than 10.

Substitute with t = 15

Left hand side = 47

Right-hand side = 65

t = 20

Left-hand side = 37

45

t = 25

Left-hand side = 29

Right-hand side =25

t = 24

Left-hand side =3 0

Right hand side = 29

Hence, 24 seconds is a satisfactory solution.

The graph attached shows that the intersection point is at t ≈ 23.548 seconds, confirming that 24 seconds is the best solution rounded to an integer number.

Hence, At t= 24 , in seconds, will there be equal quantities of both substances.

Answer:

B) 3x+5

Step-by-step explanation:

Let's suppose that x is equal to the sum of a number.  That means, that 3x needs to be somewhere in the variable equation.  "And 5", means to add, so +5 also needs to be somehwere in the equation.  Giving you 3x + 5 as the answer.  Now you might be thinking, "But what about C? Isn't it basically the same answer as B?"  The answer to THAT question is NO.  For it to be the same as B, you would have to get rid of the parenthesis.  This is because when there's a parenthesis, it means that it is the first thing you have to do in the equation.  But that is not what we want.  We do not want the sum of a number to be added to 5.  We want it to be multiplied by 3.  So that is why C is the not the same as B.  B is yoir correct answer.

In this question, the student is asked to compare mean, median, mode, and range for a given data set. Among these measures, the range, being 17, is the greatest.

The question given is asking for the greatest measure among the data set, which is 3,3,4,5,6,8,16,20. The measures being referred to are likely statistical measures such as mean, median, mode, and range.

The mean is the sum of all the numbers divided by the total count of the numbers, the median is the middle value when the numbers are arranged in order, the mode is the number that appears most frequently, and the range is the difference between the largest and smallest numbers.

To find the mean, we calculate (3+3+4+5+6+8+16+20)/8=7.875. The median is the average of the two middle numbers since we have an even count, (5+6)/2 = 5.5. This data set's mode is 3 since 3 repeats only. The range is 20 - 3 = 17.

Comparing these measures, we see that the range, with a value of 17, is the greatest.

Answer:

No

Step-by-step explanation:

Three segments 4cm, 6cm, and 11cm cannot form a right triangle because if they could, then by Pythagorean theorem, 4^2 + 6^2 = 11^2, which is not true.

Moreover, the three segments cannot form an acute or obtuse triangle because by Triangle Inequality Theorem, the sum of two sides has to be greater than the third side. Here, (4cm + 6cm) is NOT larger than 11cm, and thus you cannot form a triangle.

Using triangle concepts, it is found that the sides with these lengths cannot form a triangle.

In a triangle, the sum of the lengths of the two smaller sides has to be greater than the length of the larger side.

In this problem:

[tex]4 + 6 = 10 < 11[/tex]

Since the larger side length is greater than the sum of the lengths of the smaller sides, a triangle cannot be formed.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Graph transformation is the process by which an existing graph, or graphed equation, is modified to produce a variation of the proceeding graph

When a point is reflected across the line y = x, the x-coordinates and y-coordinates change their place.

Without specific figures or numerical data, we cannot conclusively calculate the exact lengths of segments e and f. However, geometric principles suggest that segment f, if similar to a hypotenuse, would be longer. Accurate measurement or calculations based on the context (geometry, trigonometry, physical surveying) are required to determine the length of segments.

To calculate the exact lengths of segment e and segment f, we need more specific information from the given figures. However, based on the information provided, we can infer certain principles that could lead us to a conclusion. The hypotenuse of a right-angle triangle, as mentioned, is always the longest side, which implies that the length of segment f, being akin to a hypotenuse, would be longer than segment e if these segments were sides of a right-angled triangle. Additionally, the concept of eccentricity described for an ellipse informs us about the ratio of distances and could be applied if the segments were part of an elliptical geometry. The surveyor's tapes information suggests that lengths must be measured accurately, taking into account environmental factors such as temperature, because this can affect the length measurements. Without specific numerical data or figures to reference, we cannot determine with certainty which segment is longer, but the principles outlined can guide us to make an educated conclusion once all data is available.

In general, when comparing two segments to determine which is longer, measurement tools or mathematical calculations are utilized based on the context, such as geometry, trigonometry, or physical measurement in the case of surveying. As per the given text, if the discussion revolves around visual illusions where segments appear different in length despite being the same, then careful measurement is necessary to establish their actual lengths.

Answer:

x=-2

Step-by-step explanation:

You can substitute the first equation into the second:

-3x+3=5x+19

Add 3x on both sides:

3=8x+19

Subtract 19 on both sides:

-16=8x

Divide 8 on both sides:

x=-2

Answer:

x = -2

y = 9

Step-by-step explanation:

to evaluate this system of equation we would say that

let

Y=-3x+3................................................. equation 1

Y=5x+19................................................... equation2

substitute equation 2 into equation 1

5x + 19 = -3x + 3

collect the like terms together

5x + 3x = 3 -19

8x = -16

divide both sides by the coefficient of x which is 8

8x/8 = -16/8

x = -2

put x = -8 into equation 1

Y=-3x+3................................................. equation 1

y = -3(-2) + 3

y = 6 + 3

y = 9

therefore the value of x and y is -2 and 9 respectively.

1308 33 cubic millimeters

Hello! I wrote the complete question in a comment above. The volume of a cylinder is defined as:

[tex]V_{c}=\pi r^2 h \\ \\ r:radius \\ \\ h:height[/tex]

While the volume of half a sphere is:

[tex]V_{hs}=\frac{2}{3}\pi r^3[/tex]

Since we have 2 half spheres, then the volume of these is the same as the volume of a sphere:

[tex]V_{s}=\frac{4}{3}\pi r^3[/tex]

Then, the composite figure is:

[tex]V=\pi r^2 h +\frac{4}{3}\pi r^3 \\ \\ V=\pi r^2(h+\frac{4}{3}r)[/tex]

The radius of the cylinder is the same of the radius of each half sphere. So:

[tex]r=5mm \\ \\ h=10mm \\ \\ \\ V=(3.14) (5)^2((10)+\frac{4}{3}(5)) \\ \\ V=25(3.14)(10+\frac{20}{3}) \\ \\ \boxed{V\approx 1308.33mm^3}[/tex]

Step-by-step explanation:

This problem bothers on mensuration of solid shapes, this in particular a cylindrical

Given data

Volume of cylinder in inches v=301.44in^3

Height of the bucket h= 6 inches

Radius r=?

To solve for the diameter we neeed to solve for the radius and multiply It by 2 to get the diameter

We know that the volume of a cylinder is given as

v= πr^2h

301.44= 3.142*r^2*6

301.44= 18.85*r^2

r^2= 301.44/18.85

r^2= 15.99

r=√15.99

r=3.998in

We know that the

To find:

The slope-intercept form of the equation of the line.

Solution:

[tex]$y-3=\frac{1}{2}(x+3)[/tex]

Slope of this line = [tex]\frac{1}{2}[/tex].

Slope of the line is same as the slope of  [tex]y-3=\frac{1}{2}(x+3)[/tex].

Slope of the line (m) = [tex]\frac{1}{2}[/tex]

General form of line:

y = mx + b

[tex]y=\frac{1}{2} x+b[/tex] ---------- (1)

It contains the point (8, 4). Substitute x = 8 and y = 4 in (1).

[tex]4=\frac{1}{2}( 8)+b[/tex]

[tex]4=4+b[/tex]

Subtract 4 from both sides, we get

b = 0

Substitute b = 0 in (1).

[tex]y=\frac{1}{2} x+0[/tex]

[tex]$y=\frac{1}{2} x[/tex]

Complete the sentence:

[tex]y=\frac{1}{2} x[/tex]; I used the general form of a line in slope-intercept form, y = mx + b. The slope, m is [tex]\frac{1}{2}[/tex]. Then I substituted 8 for x and 4 for y into the standard form and solved for b, which is 0.

Given:

side length = 6 ft

To find:

The area of the figure

Solution:

Area of the square = side × side

                               = 6 × 6

Area of the square = 36 ft²

Diameter of the semi-circle = 6 ft

Radius of the semi-circle = 6 ÷ 2 = 3 ft

Area of the semi-circle = [tex]\frac{1}{2} \pi r^2[/tex]

                                      [tex]$=\frac{1}{2} \times 3.14 \times 3^2[/tex]

Area of the semi-circle = 14.13 ft²

Area of the figure = Area of the square - Area of the semi-circle

                              = 36 ft² - 14.13 ft²

                              = 21.87 ft²

Area of the figure = 21.9 ft²

The area of the figure is 21.9 ft².
