The height of a right circular cylinder is 1.5 times the radius of the base. What is the ratio of the total surface area to the lateral (curved) surface area of the cylinder?

Answers

Answer 1

Answer:

The ratio of the total surface area to the lateral (curved) surface area of the cylinder is 5:3

Step-by-step explanation:

The height of a right circular cylinder is 1.5 times the radius of the base.

Let the radius of base be x

So, Height of a right circular cylinder = 1.5x

Total surface area of cylinder =[tex]2 \pi r h + 2 \pi r^2 = 2 \pi r(h+r)=2 \pi \times x(x+1.5x)=2 \pi \times x \times 2.5x[/tex]

Curved surface area of cylinder = [tex]2 \pi rh = 2 \pi \times x \times 1.5 x[/tex]

So, Ratio of the total surface area to the lateral (curved) surface area of the cylinder = [tex]\frac{2 \pi \times x \times 2.5x}{2 \pi \times x \times 1.5 x}=\frac{2.5}{1.5}=\frac{25}{15}=\frac{5}{3}[/tex]

Hence the ratio of the total surface area to the lateral (curved) surface area of the cylinder is 5:3

What is the range of possible sizes for side xxx? < x <

Answers

According to the theory of the Triangle Inequality, so, the total of the 2 sides of the triangle must be larger than the length of the third side. Therefore, the possible length of a triangle is given by the difference of two sides x the sum of two sides.

Therefore,

[tex]\to 4.3-2.1< x <4.3+2.1 \\\\\to 2.2< x <6.4 \\\\[/tex]

So, the final answer is "[tex]2.2<x<6.4[/tex]" which is the possible length of x.

Final answer:

The range of possible sizes for side 'x' is from 1.5 to 4.5, inclusive of both endpoints.

Explanation:

The question "What is the range of possible sizes for side xxx?" refers to finding the possible values that the variable 'x' can take. From the information provided, we understand that 'x' can be any number in the inclusive range from 1.5 to 4.5, which can be denoted mathematically as 1.5 ≤ x ≤ 4.5. This means that the smallest value 'x' can be is 1.5, and the largest value is 4.5. The range of possible sizes for 'x' is therefore between 1.5 and 4.5, including both of these endpoints.

Rectangle QUAD has coordinates​ Q(4,5), U(4,10),​ A(11,10), and​ D(11,5). Upper Q prime Upper U prime Upper A prime Upper D primeQ′U′A′D′ is the image of QUAD after a dilation with center​ (0,0) and scale factor 5. What is the length of segment Upper Q prime Upper U primeQ′U′​?

Answers

Answer:

25

Step-by-step explanation:

Answer: 25

find the length of segment QU.  

First, we must find out what the coordinates are.

Q=(4,5) U=(4,10)

Then, Setup your equation by making the first coordinate pair equal. So,

Q= (4,5) would now equal Q=(5,5). That means we added 1. (when you add x ((x=the number you add to make equal)) you add x to the other side as well)

So, now we would add 1 (or how many you got) to U. Thus,

U=(4,10) would now equal Q=(5,10).

Next, set up the equation.

[tex]\sqrt{(Q)^{2} +(U)^{2}[/tex] (Q=(5,5) and U=(5,10).)

* You will now be subtracting the coordinates so, Q=(5-5) and U=(5-10)*

Next, Substitute the equation.

[tex]\sqrt{(5-5^{2} +(5-10)^{2}[/tex]

After, we solve.

[tex]\sqrt{0^{2} +(5-10)^{2}[/tex]

*the sum of two opposites equals 0. 5-5=0*

Next, Subtract (5-10).

[tex]\sqrt{0^{2} +(-5)^{2}[/tex]

Next, 0 raised to any positive power equals 0

[tex]\sqrt{0+(-5)^{2}[/tex]

Next, When adding or subtracting 0, the quantity does not change.

[tex]\sqrt{(-5)^{2}[/tex]

Next, Reduce the index of the radical and exponent 2.

[tex]|-5| = 5[/tex]

So, The length of segment is 5.

Now, find the length of segment Upper Q'U'​, multiply the length of segment QU by the scale factor.

scale factor in this equation is 5.

Now, multiply.

5·5 = 25

So, the length of segment Q'U' is 25.

The length of segment Q'U' after the dilation with a scale factor of 5 is 25 units.

To find the length of segment Q'U'  after the dilation with a scale factor of 5, we can calculate it step by step:

1. Calculate the new coordinates of Q'  and U'  after the dilation with a scale factor of 5 and center (0,0):

Q' coordinates: (4 5, 5 5) = (20, 25)

U' coordinates: (4 5, 10 5) = (20, 50)

2. Determine the distance between Q'  and U' using the distance formula:
- Horizontal distance: 20 - 20 = 0
- Vertical distance: 50 - 25 = 25

3. Calculate the length of segment

 using the Pythagorean theorem:
- Length = sqrt(0^2 + 25^2)
- Length = sqrt(0 + 625)
- Length = sqrt(625)
- Length = 25 units

Therefore, the length of segment Q'U' after the dilation with a scale factor of 5 is 25 units.

He has between 10 and 20 batteries. He counts the batteries by putting them into piles of 4 and finds that he has 3 left over. He then counted them by putting them into piles of 3 and found that he had one left over. How many batteries does he have?

Answers

Answer:

15 batteries

Step-by-step explanation:

If he puts the batteries in piles of 4, and there is 3 left over, the number of batteries he can have is:

2 piles: 4*2 + 3 = 11

3 piles: 4*3 + 3 = 15

4 piles: 4*4 + 3 = 19

Then, when he puts in piles of 3, there is no batteries left over, so the number of batteries is a multiple of 3.

From the 3 possibilities above (11, 15 and 19), only the number 15 is a multiple of 3, so the number of batteries is 15.

Which is the graph of f(x) = -(x + 3)(x + 1)?

Answers

Answer:

Step-by-step explanation:

Setting f(x) = -(x + 3)(x + 1) = 0 leads to identifying two roots/solutions of this equation:  x = -3 and x = -1.  The axis of symmetry is a vertical line halfway between these two roots:  x = -2.  This x = -2 is also the x-coordinate of the vertex.  Evaluating f(x) = -(x + 3)(x + 1) at x = -2 gives us the y-coordinate of the vertex:  y = -(-2 + 3)(-2 + 1) = -(1)(-1) = 1.

In summary, the vertex is at (-2, 1) and the two x-intercepts are (-3, 0) and (-1, 0).  The y-intercept is found by  setting x = 0 and finding y:  

f(0) = -(0 + 3)(0 + 1) = -3, or (0, -3)

What range of values represents the upper 2.5% of the data?

a

X > 235.3

b

X > 333.1

c

X > 284.2

d

X > 186.4

Answers

We have been given that a normal distribution has a mean of 186.4 and a standard deviation of 48.9. We are asked to find the range of value that represents the upper 2.5% of the data.

We know that upper 2.5% of data would be 97.5% of data.

We will use z-score formula to solve our given problem.  

[tex]z=\frac{x-\mu}{\sigma}[/tex], where,

z = z-score,

x = Random sample score,

[tex]\mu[/tex] = Mean,

[tex]\sigma[/tex] = Standard deviation.

Now we will use normal distribution table to find z-score corresponding to 97.5% area or 0.975.

We can see from the normal distribution table that z-score corresponding to  area 0.975 is [tex]1.96[/tex].

[tex]1.96=\frac{x-186.4}{48.9}[/tex]

Let us solve for x.

[tex]1.96\cdot 48.9=\frac{x-186.4}{48.9}\cdot 48.9[/tex]

[tex]95.844=x-186.4[/tex]

[tex]95.844+186.4=x-186.4+186.4[/tex]

[tex]282.244=x[/tex]

Therefore, the range [tex]x>282.244[/tex] represents the upper 2.5% of the data.

Step-by-step explanation:

Jason owns a food truck that sells tacos and burritos. He sells each taco for $4.75 and each burrito for $7.50. Yesterday Jason made a total of $790 in revenue from all burrito and taco sales and there were twice as many burritos sold as there were tacos sold. Write a system of equations that could be used to determine the number of tacos sold and the number of burritos sold. Define the variables that you use to write the system.

Answers

let t be the number of tacos sold

let b be the number of burritos sold

Step-by-step explanation:

b=2t

4.75t+7.50b=790

Final answer:

To solve the problem, set up two variables T and B for the number of tacos and burritos sold. Two equations are formed: B = 2T (since twice as many burritos as tacos were sold) and 4.75T + 7.50B = 790 (from the total revenue). Solve these to find T and B.

Explanation:

To determine the number of tacos and burritos sold by Jason's food truck, we need to establish two variables: let T represent the number of tacos sold, and let B represent the number of burritos sold. Given that burritos are sold at a ratio of two to every one taco, we can express this relationship with the equation B = 2T. Next, using the given prices of tacos ($4.75) and burritos ($7.50), along with the total revenue of $790, we can write the budget constraint equation as 4.75T + 7.50B = 790. These two equations together form the system of equations that can be solved to find the number of tacos (T) and burritos (B) sold.

The length (L) of the ladder is given as:

The distance up the ladder is the height (h) of the ladder on the wall.

This is calculated using the following Pythagoras theorem

Answers

Answer:

Density of the Cylinder = 2.7 g/mm³

Step-by-step explanation:

Density of a cylinder is calculated using the formula =

Mass of the Cylinder ÷ Volume of the Cylinder

Step 1

The First step is to find the Volume of the Cylinder.

Volume of a Cylinder = πr²h

In the attached image , we are given:

Diameter of the Cylinder = 28mm

Radius of the Cylinder = Diameter ÷ 2 = 28mm ÷ 2

Radius of the Cylinder (r) = 14mm

Height of the Cylinder (h) = 30mm

The Volume of the Cylinder = πr²h

= π × (14mm)² × 30mm

= 18472.564803 mm³

Step 2

The second step would be to find the Density of the Cylinder.

Density of the Cylinder = Mass of the Cylinder ÷ Volume of the Cylinder

Mass of the Cylinder = 50,000g

Volume of the Cylinder = 18472.564803 mm³

Density of the Cylinder = 50,000g ÷ 18472.564803 mm³

= 2.7067167193 g /mm³

Approximately the Density of the Cylinder = 2.7 g/mm³

A house purchased for $226,000 has lost 4% of its value each year for the past five years. What is it worth now?

Answers

Answer:

The answer would be $184,274.23.

Step-by-step explanation:

Final answer:

After a 4% annual decrease in value over five years, a house that was bought for $226,000 would be worth around $183,896.7.

Explanation:

The student's question pertains to a situation where a house's value depreciates, in this case, at a rate of 4% per year for five years. To find out how much the house would be worth now, we need to employ the formula for depreciations, that is P = P0 (1 - r)^n, where P is the final value, P0 the initial value, r the rate of decrease and n the number of periods the decrease has occurred over.

In this case, P0 would be the initial value of the house $226,000, r would be 4% (or 0.04 as a decimal), and n would be the number of years, which is 5. Substituting these values into the formula gives us and calculated we get P = $226,000 * (1 - 0.04)^5 = $183,896.7.

So after a 4% annual decrease in value over five years, the house that was bought for $226,000 would now be worth around $183,896.7.
