Answer:

C. V = two-thirds (27)

Step-by-step explanation:

Given

Solid Shapes: Cylinder and Sphere

Volume of Cylinder = 27π ft³

Required

Volume of the sphere.

From the question,

We have that

1.  The volume of the sphere is the same as the volume of the cylinder

2. The height of the sphere is the same as the height of the cylinder.

From (2) above;

This means that the height of the cylinder equals the diameter of the sphere.

Let h represent the height of the sphere and d represent the diameter of sphere.

Mathematical, d = h

Recall that radius, r = [tex]r = \frac{d}{2}[/tex]

Substitute h for d in the above expression

[tex]r = \frac{h}{2}[/tex]. ----- (take note of this)

Calculating the volume of a cylinder.

V = πr²h

Recall that  V = 27; This gives us

27 = πr²h

Divide both sides by h

[tex]\pi r^2 = \frac{27}{h}[/tex]

-------------------

Calculating the volume of a sphere

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

Expand the above expression

[tex]V = \frac{4}{3}\pi r^2 * r[/tex]

Substitute [tex]\pi r^2 = \frac{27}{h}[/tex]

[tex]V = \frac{4}{3} * \frac{27}{h} * r[/tex]

Recall that [tex]r = \frac{h}{2}[/tex]

So,

[tex]V = \frac{4}{3} * \frac{27}{h} * \frac{h}{2}[/tex]

[tex]V = \frac{4}{3} * \frac{27}{2}[/tex]

[tex]V = \frac{2}{3} * 27[/tex]

[tex]V = \frac{2}{3} (27)[/tex]

V = two-third (27)

Answer:

The cat weighs more.

Step-by-step explanation:

The cat weighs 4.08 kilograms and the pumpkin weighs 3.2 kilograms.

9lbs=4.08 kilograms.

Hope this helps : )

The body that weighs more, based on its relative mass is the cat.

The cat weighs 9 pounds and the pumpkin weighs 3.2 kilograms.

To know which weighs more, they need to be weighed in the same units.

Convert the cat to kilograms:

= Number of pounds x Pounds to kilograms

= 9 x 0.45

= 4.05 kg

The cat therefore weighs more than the pumpkin.

Answer:

triangular pyramid

Step-by-step explanation:

Let's make the central triangle the "base", or the bottom face, of our polyhedron. Try to visualise what will happen if we fold up the three triangles so that their top vertices meet at the center top (see diagram).

If we can do that, we'll see that it's a pyramid with a triangular base, so it's a triangular pyramid.

Answer:

y 1 = StartFraction log x Over log 0.5 EndFraction, y 2 = StartFraction log 2 Over log 3 EndFraction + x

Step-by-step explanation:

To solve the log equation, the appropriate system of equations is y₁ =  log₀.₅ x and y₂ =  log₃(2+x) as these correspond to the format of the original log equation, where we can equate the two and solve for x.

To solve the equation log₀.₅ₓ = log₃ (2+x), we can rewrite it in a form that helps us find a system of equations.

First, apply the change of base formula for logarithms:

log ab/ log ac = log cb.

Using this formula, we can rewrite the given equation as:

log 0.5x / log₀.₅ 10 = log₃(2+x) / log₃10

Now, we can create a system of equations with the following relationships:

y₁ = log₀.₅ x / log₀.₅10

y₂ = log₃(2+x) / log₃10

Therefore, the correct choice is:

y₁ = logₓ/log₀.₅ , y₂=  log(2+x)/ log 3

Answer:

t = - 3, t = - 1

Step-by-step explanation:

Given

h(t) = t² + 4t + 3

To find the zeros equate h(t) to zero, that is

t² + 4t + 3 = 0

Consider the factors of the constant term (+ 3) which sum to give the coefficient of the t- term

The factors are + 3 and + 1, since

3 × 1 = 3 and 3 + 1 = 4, thus

t² + 4t + 3 = (t + 3)(t + 1) = 0

Equate each factor to 0 and solve for t

t + 3 = 0 ⇒ t = - 3

t + 1 = 0 ⇒ t = - 1

smaller zero is t = - 3

larger zero is t = - 1

Answer:

[tex] \mu_{\bar X} = 90[/tex]

[tex] \sigma_{\bar X} =\frac{\sigma}{\sqrt{n}}= \frac{9.6}{\sqrt{144}}= 0.8[/tex]

Step-by-step explanation:

For this case we have a population with the following parameters:

[tex]\mu = 90, \sigma =9.6[/tex]

For this case we have a sample of n= 144 and this sample size is larger (>30) then we can apply the central limit theorem and the distirbution for the sample mean is given by:

[tex] \bar X \sim N( \mu, \frac{\sigma}{\sqrt{n}}) [/tex]

And replacing we got:

[tex] \mu_{\bar X} = 90[/tex]

And the standard deviation is given by:

[tex] \sigma_{\bar X} =\frac{\sigma}{\sqrt{n}}= \frac{9.6}{\sqrt{144}}= 0.8[/tex]

B=a/h

The missing base in the figure is 5 centimeter.

The area of a parallelogram is the product of the base and the height of the figure. Supposing that there is no direct formula available for deriving the area, we can derive the area of that region by dividing it into smaller pieces, whose area can be known directly. Then summing all those pieces' area gives us the area of the main big region.

The area of a parallelogram = Base x Height

Given;

     Area of parallelogram= 40 square centimeters

      Height of parallelogram= 8cm

Solution;

       A= b x h

   substituting the given values in the formula;

                 40= b x 8

                  b= 40/8

                   b= 5

So, the answer is 5cm

Statement 1 & Statement 3

Step-by-step explanation:

4 ÷ 10/3

4 × 3/10

12/10

6/5

f(x + 1) = (6/5) × f(x)

f(x) = (10/3) × (6/5)^(x-1)

f(x) = (10/3) × (5/6) × (6/5)^x

f(x) = (25/9) × (6/5)^x

The domain is all natural numbers and the range is real numbers

Step-by-step explanation:

Step 1:  Find the correct answer

Option A is correct because if you plug in the numbers...

[tex]f(0 + 1) = \frac{10}{3}[/tex] → [tex]f(1)=\frac{10}{3}[/tex]

[tex]f(1 + 1) = \frac{6}{5} * \frac{10}{3}[/tex] → [tex]f(2)=4[/tex]

[tex]f(2 + 1) = \frac{6}{5} * \frac{4}{1}[/tex] → [tex]f(3) = \frac{24}{5}[/tex]

[tex]f(3 + 1) = \frac{6}{5} * \frac{24}{5}[/tex] → [tex]f(4) = \frac{144}{25}[/tex]

Also, Option C is correct because if you plug in the numbers...

[tex]f(1) = \frac{10}{3}(\frac{6}{5})^(^1^-^1^)[/tex] → [tex]f(1) = \frac{10}{3} * 1[/tex] → [tex]f(1)=\frac{10}{3}[/tex]

[tex]f(2) = \frac{10}{3}(\frac{6}{5})^(^2^-^1^)[/tex] → [tex]f(2) = \frac{10}{3}*\frac{6}{5}[/tex] → [tex]f(2) = 4[/tex]

[tex]f(3) = \frac{10}{3}(\frac{6}{5})^(^3^-^1^)[/tex] → [tex]f(3) = \frac{10}{3}*\frac{36}{25}[/tex] → [tex]f(3) = \frac{24}{5}[/tex]

[tex]f(4) = \frac{10}{3}(\frac{6}{5})^(^4^-^1^)[/tex] → [tex]f(4) = \frac{10}{3} * \frac{216}{125}[/tex] → [tex]f(4) = \frac{144}{25}[/tex]

The reason why option B is not correct is because when you plug in a number, the output is incorrect.  The reason why Option D is not correct is because the domain does not include negative numbers which means that the domain is all natural numbers.  The reason why Option E is not correct is because the range is all real numbers and not just natural/positive numbers.

The small tire would make about  127 rotations.

The large tire would make about  38 rotations.

b. Would you rather ride a bicycle made with two large wheels or two small wheels? Explain.

Two large wheels. Because the larger wheel makes a smoother ride and you spend less energy in order to move, compared to smaller wheels. Also, the larger the diameter, the further it can travel over one revolution.

A bicycle with would allow you to travel farther with each rotation of the pedal.

The larger one. Because in one rotation the larger wheel moves 188.49 inches and the smaller one 56.55 inches.

[tex]C= 188.49\text{inches}[/tex]

[tex]C= 56.55\text{inches}[/tex]

Step-by-step explanation:

- Big wheel 60 inches

- Small wheel 18 inches.

a. How many rotations does each tire make after traveling 600 feet? Round your answers to the nearest whole number.

Considering: [tex]C=\pi d[/tex]

Large tire:

[tex]C=60\pi[/tex]

[tex]C= 188.49\text{inches}[/tex]

[tex]$C=\frac{188.49}{12} = 15.7 \text{feet}$[/tex]

[tex]$\frac{600 }{15.7} = 38 \text{rotations}$[/tex]

Small tire:

[tex]C=18\pi[/tex]

[tex]C= 56.55\text{inches}[/tex]

[tex]$C=\frac{56.55}{12} = 4.71 \text{feet}$[/tex]

[tex]$\frac{600 }{4.71} = 127 \text{rotations}$[/tex]

We have been given that the value of Vishal's car is depreciating exponentially.  The relationship between V, the value of his car, in dollars, and t, the elapsed time, in years, since he purchased the car is modeled by the equation [tex]V=22,500\cdot 10^{-\frac{t}{12}}[/tex]. We are asked to find the time, when Vishal's car will be worth $10,000.

To find the time, we will equate our given equation with 10,000 as:

[tex]10,000=22,500\cdot 10^{-\frac{t}{12}}[/tex]  

[tex]\frac{10,000}{22,500}=\frac{22,500\cdot 10^{-\frac{t}{12}}}{22,500}[/tex]

[tex]\frac{4}{9}=10^{-\frac{t}{12}}[/tex]

Now we will take log on both sides.

[tex]log_{10}\left(\frac{4}{9}\right)=log_{10}\left(10^{-\frac{t}{12}}\right)[/tex]

[tex]log_{10}\left((\frac{2}{3})^2\right)=-\frac{t}{12}[/tex]

[tex]-\frac{t}{12}=log_{10}\left((\frac{2}{3})^2\right)[/tex]

[tex]-\frac{t}{12}(-12)=(-12)log_{10}\left((\frac{2}{3})^2\right)[/tex]

[tex]t=(-12)log_{10}\left((\frac{2}{3})^2\right)[/tex]

Using property [tex]log(a^b)=b\cdot log(a)[/tex], we will get:

[tex]t=(-12)\cdot 2log_{10}\left(\frac{2}{3}\right)[/tex]

[tex]t=-24log_{10}\left(\frac{2}{3}\right)[/tex]

Therefore, the value of Vishal's car will be $10,000 after approximately  [tex]-24log_{10}\left(\frac{2}{3}\right)[/tex] years.

Answer:

48 video games were sold.

Step-by-step explanation:

We know that both 100% and 60 are divisable by 5. 100%÷5=20%. 60÷5=12. So now we know that 20% of 60 is 12. We need 80%, however. To get from 20% to 80%, we just multiply by four. 20 × 4 = 80. But what we do to one side, we must do to the other. 12×4=48. So 80% of 60 is 48.
