Step-by-step explanation:

The volume of the traffic pylon is 7.26 cubic feet.

To find the volume of the cone-shaped pylon, we'll use the formula for the volume of a cone, which is [tex]\( \frac{1}{3} \pi r^2 h \),[/tex]  where ( r ) is the radius of the base and ( h ) is the height.

Given that the height ( h ) of the pylon is 2.4 feet and the radius ( r ) is 1.7 feet, we can plug these values into the formula:

[tex]\[\text{Volume} = \frac{1}{3} \pi \times (1.7)^2 \times 2.4\][/tex]

Let's calculate this:

[tex]\[\text{Volume} \approx \frac{1}{3} \times 3.14159 \times (1.7)^2 \times 2.4\][/tex]

[tex]\[\text{Volume} \approx \frac{1}{3} \times 3.14159 \times 2.89 \times 2.4\][/tex]

[tex]\[\text{Volume} \approx \frac{1}{3} \times 3.14159 \times 6.936\][/tex]

[tex]\[\text{Volume} \approx \frac{1}{3} \times 21.78\][/tex]

[tex]\[\text{Volume} \approx 7.26 \text{ cubic feet}\][/tex]

So, the volume of the cone-shaped pylon is approximately 7.26 cubic feet.

Step-by-step explanation:

[tex]\frac{1}{4}b+6=16[/tex]

Subtract 6 from both sides,

[tex]\frac{1}{4}b+6-6=16-6\\\\\frac{1}{4}b=10\\\\b=10*4\\b=40[/tex]

Answer:

40 beads

Step-by-step explanation:

We want to find how many beads, b are being used

1/4b+6=16

To do this, we have to solve for b, by getting b by itself.

First, move all the constants to the same side. Subtract 6 from both sides, since it is being added to 1/4b.

1/4b+6-6=16-6

1/4b=10

Next, divide both sides by 1/4, or multiply both sides by the reciprocal of 1/4.

To find the reciprocal, flip the numerator (top number) and denominator(bottom number)

1/4–> 4/1

4/1*1/4b=10*4/1

The 1/4 will cancel, leaving us with:

b=10*4/1

b=40

Final answer:

To find the solution, add 91, 129, and 16 to get a sum of 236. Then divide this sum by 44 to get approximately 5.364.

Explanation:

To solve the given problem, we need to perform two steps: first, add the numbers together; second, divide the sum by 44.

Add 91, 129, and 16 together.

Divide the sum by 44.

We start by adding the numbers:

91 + 129 + 16 = 236

Next, we divide the sum by 44:

236 ÷ 44 = 5.363636...

The division yields a repeated decimal which we can round to a desired decimal place if necessary. In this context, we'll keep it as is or round it to the nearest thousandth, which would be approximately 5.364.

Answer:

I think the answer is 42.

Step-by-step explanation:

I estimated 23.1 to 23 miles then I estimated 19.24 to 24 and added 23+19=42. But I don't know if that is correct because there was no specification if we round to the whole number.

The actual distance is 42.34 miles. The total distance Pablo drove, is sum of distance of aunt's house an friend's house.

Pablo drove 23.1 miles to his aunt's house and then 19.24 miles to his friend's house.

To estimate the total distance driven, he can round the numbers to the nearest mile or to the nearest tenth to make the calculation easier. If rounding to the nearest mile, he can estimate 23 + 19 miles, which is 42 miles.

If rounding to the nearest tenth, he can estimate

23.1 + 19.2= 42.3 miles.

The actual total distance driven is 23.1 + 19.24 = 42.34 miles.

Step-by-step explanation:

Every second, the number of harmful bacteria remaining in the body decays by a factor of approximately .

To determine the rate of change in the number of harmful bacteria remaining in the body every second, we need to convert the time in the given function from minutes to seconds. The function provided is

⇒ [tex]H_{minute}[/tex](t) = 500,000,000 · [tex](0.2)^t[/tex].

A minute has 60 seconds, so we need to express the decay factor for a second. By letting t = [tex]t_{seconds}[/tex] ÷ 60, we can rewrite the function in terms of seconds:

⇒ [tex]H_{second}[/tex](t) = 500,000,000 · [tex](0.2)^\frac{t}{60}[/tex].

For every passing second, the decay factor is [tex](0.2)^\frac{1}{60}[/tex]. Using a calculator, we find:

⇒ [tex](0.2)^\frac{1}{60}[/tex] ≈ 0.98855,

rounded to two decimal places.

Therefore, every second, the number of harmful bacteria remaining in the body decays by a factor of approximately 0.99.

Answer:

The most correct option is;

(B) 958.2 ft.²

Step-by-step explanation:

From the question, the dimension of each square = 3 ft.²

Therefore, the length of the sides of the square = √3 ft.

Based on the above dimensions, the dimension of the small semicircle is found by counting the number of square sides ti subtends as follows;

The dimension of the diameter of the small semicircle = 10·√3

Radius of the small semicircle = Diameter/2 = 10·√3/2 = 5·√3

Area of the small semicircle = (π·r²)/2 = (π×(5·√3)²)/2 = 117.81 ft.²

Similarly;

The dimension of the diameter of the large semicircle = 10·√3 + 2 × 6 × √3

∴ The dimension of the diameter of the large semicircle = 22·√3

Radius of the large semicircle = Diameter/2 = 22·√3/2 = 11·√3

Area of the large semicircle = (π·r²)/2 = (π×(11·√3)²)/2 = 570.2 ft.²

Area of rectangle = 11·√3 × 17·√3 = 561

Area, A of large semicircle cutting into the rectangle is found as follows;

[tex]A_{(segment \, of \, semicircle)} = \frac{1}{4} \times (\theta - sin\theta) \times r^2[/tex]

Where:

[tex]\theta = 2\times tan^{-1}( \frac{The \, number \, of \, vertical \, squrare \, sides \ cut \, by \ the \ large \, semicircle}{The \, number \, of \, horizontal \, squrare \, sides \ cut \, by \ the \ large \, semicircle} )[/tex]

[tex]\therefore \theta = 2\times tan^{-1}( \frac{10\cdot \sqrt{3} }{5\cdot \sqrt{3}} ) = 2.214[/tex]

Hence;

[tex]A_{(segment \, of \, semicircle)} = \frac{1}{4} \times (2.214 - sin2.214) \times (11\cdot\sqrt{3} )^2 = 128.3 \, ft^2[/tex]

Therefore; t

The area covered by the pavers = 561 - 128.3 + 570.2 - 117.81 = 885.19 ft²

Therefor, the most correct option is (B) 958.2 ft.².

Step-by-step explanation:

To graph y=4x-9, plot the y-intercept at (0,-9), then for each increase in x, y increases by 4. Draw a line through these points to describe the equation.

To graph the equation y=4x-9, we need to identify the slope and the y-intercept. In this case the slope is 4, which means for each increase in x by 1, y increases by 4. The y-intercept is -9, which is the point where the line crosses the y-axis.

Start by plotting the y-intercept at (0,-9) on the graph. Then, for each unit increase in x, move up 4 units on the y-axis from the previous point. Drawing a line through these points will visualize the equation y=4x-9.

Answer:

= 80πcm²

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  

Please have a look at the attached photo.  

My answer:

Given the information:

=> Area of base = π(6²) = 36π cm²

=> Area of the hole = πr² = π(4²) = 16πcm²

As we know that, the surface area of the piece of wood has to be painted at base:

= Base area - area of hole

= 36π cm² - 16πcm²  

= 20πcm²

For the curved surface area can be determined by the following formula:

Area = πrl where l is the slant height

Applying Pythagoras theorem, we have:

[tex]l^{2} = r^{2} + h^{2}[/tex]

<=> [tex]l^{2} = 6^{2} + 8^{2}[/tex]

<=> [tex]l^{2} =100[/tex]

<=> l =10

=> the curved surface area is: π*6*10 =60πcm²

Hence the total surface area to be painted is

= the curved surface area + he surface area of the piece of wood has to be painted at base

=  60πcm² +20πcm²

= 80πcm²

Hope it will find you well.

To find the surface area to be painted, calculate the total surface area of the cone and subtract the area of the cylindrical hole.

To find the surface area to be painted, we need to calculate the total surface area of the cone and then subtract the area of the cylindrical hole.

The total surface area of a cone is given by the formula A = πr(r + l), where r is the radius of the base and l is the slant height.

In this case, the radius of the cone is the same as the radius of the base of the hole, which is 4 cm. We need to find the slant height of the cone, l.

By applying the Pythagorean theorem to the right triangle formed by the height of the cone, the slant height, and the radius of the cone, we can calculate the slant height as l = sqrt( h^2 + 4^2 ), where h is the height of the cone.

Since the height of the cone is not given, we will not be able to find the exact value for the surface area to be painted. However, we can provide the general formula based on the given information:

Surface area to be painted = (π * r1 * (r1 + sqrt( h^2 + r1^2 ))) - (2 * π * r2 * h),

where r1 is the radius of the base of the hole and r2 is the smaller radius of the hole.

Step-by-step explanation:

First of all we all should know about a geometric progression to solve this question.

A geometric progression is a series in which there is a first term a and all the next terms are calculated by multiplying the previous term by a common number r.

where a is known as first term and

r is known as common ratio.

In the question we are given a as 20 and we have to find out 2 terms after 20 and 4th term is given as 2500.

Formula for [tex]n^{th}[/tex] term in a geometric progression is:

[tex]a_{n} = a\times r^{n-1}[/tex]

Here [tex]a_{4}[/tex] = 2500

As per formula of [tex]n^{th}[/tex] term:

[tex]a\times r^{3} = 2500\\\Rightarrow 20 \times r^{3} =2500\\\Rightarrow r^{3} = 125\\\Rightarrow r = 5[/tex]

Now, 2nd term:

[tex]a_{2} = a \times r\\\Rightarrow a_{2} = 20 \times 5\\\Rightarrow a_{2} = 100[/tex]

Now, 3rd term:

[tex]a_{3} = a \times r^{2} \\\Rightarrow a_{3} = 20 \times 5^{2}\\\Rightarrow a_{3} = 500[/tex]

So, the two geometric means between 20 and 2500 are 100 and 500.
