A teepee is designed to have a diameter of 10 ft and a volume of 366ft³ what is the height? A.15ft , b.14 ft, c 5ft, or 1 ft

Answers

Answer:

B.  14 ft approx

Step-by-step explanation:

Given data

A teepee  has a conical shape

Diameter= 10ft

radius= 5 ft

Volume = 366ft³

Height = ????

The expression for the volume is

V= 1/3πr^2 h

substitute

366= 1/3*3.142*5^2*h

366= 1/3*78.55*h

366= 26.18h

h= 366/26.18

h=13.98 ft

h= 14 ft approx

Hence the Height is 14 ft approx

Answer:

14 ft

Which of the following values are solutions to the inequality 6≥4x−5?

Answers

Answer:

The solution to the inequality is:

[tex]6\ge \:4x-5\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \frac{11}{4}\:\\ \:\mathrm{Decimal:}&\:x\le \:2.75\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:\frac{11}{4}]\end{bmatrix}[/tex]

-5 and -6 are the solution values.

Step-by-step explanation:

Given the inequality

[tex]6\ge \:4x-5[/tex]

Let us solve the inequality

[tex]6\ge \:4x-5[/tex]

switch sides

[tex]4x-5\le \:6[/tex]

Add 5 to both sides

[tex]4x-5+5\le \:6+5[/tex]

Simplify

[tex]4x\le \:11[/tex]

Divide both sides by 4

[tex]\frac{4x}{4}\le \frac{11}{4}[/tex]

Simplify

[tex]x\le \frac{11}{4}[/tex]

Thus, the solution to the inequality is:

[tex]6\ge \:4x-5\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \frac{11}{4}\:\\ \:\mathrm{Decimal:}&\:x\le \:2.75\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:\frac{11}{4}]\end{bmatrix}[/tex]

In our case, we are given the values -6, 8, and -5

We have already determined that the solution is x ≤ 2.75.

Since the solution is x ≤ 2.75, so -5 and -6 come under the solution set because -5 and -6 are less than 2.75.

Hence, -5 and -6 are the solution values.

The graph of the solution of the inequality is also attached below.

The solutions to the inequality 6 ≥ 4x − 5 is x ≤ 11/4.

What is inequality?

A statement of an order relationship-greater than, greater than or equal to, less than, less than or equal to- between two numbers or algebraic equations.

Now the given inequality is,

6 ≥ 4x − 5

Adding 5 both the side we get,

6 + 5 ≥ 4x − 5 + 5

⇒ 11 ≥ 4x

Dividing both the side by 4 we get,

11/4 ≥ 4x/4

⇒  11/4 ≥ x

or, x ≤ 11/4

this is the required solution of the given inequality.

Thus, the solutions to the inequality 6 ≥ 4x − 5 is x ≤ 11/4.

The number of observations is 10.

The median of the data set is 10.

The mean of the data set is 15.

The range of the data set is 12.

Answers

Answer:

Option 2

Step-by-step explanation:

Go through until you find a true statement:

- The number of observations is 10

Count the number of data points. You should end up with 15, so this option is not correct.

-The median of the data set is 10

To find the median, you know that there are a total of 15 data points, so the median would be the mean of the 7th and 8th (because those are the middle numbers). If you look at the data points, the 7th and 8th points are at 10. The mean of 10 and 10 is just 10,  so that means the median of the set is 10.

This is the correct answer.

If you want, you can also go through the other options and see that none of them work.

Answer:

1: 65 in^2

2. 55 ft^2

Step-by-step explanation:

1. First you have to find the area of the trapezoid using the formula (a+b)h/2 where a= 10, b=15, and h=8. The answer will be 100. Then subtract the area of the square inside, which is 35. The final answer is 65.

2. Subtract from the dimensions of the landscape to find the dimensions of the patio. The length of the patio is 11 ft and the width is 5 ft. Therefore, the area is 55 ft^2

Answer:

Alright, helping you because I feel bad. 1) 76 in. 2) 24 in.

Step-by-step explanation:

1. [tex]A= \frac{a+b}{2} h[/tex]    a= base b= base h= height   Plug in the numbers, [tex](\frac{10+15}{2} ) 8= 100[/tex], but we still need to subtract the area of the un-shaded region (5×2)+(7×2)= 24

100-24= 76

2. Find the area of both landscaping rectangles, including the patio bit.

(14×2)+(8×2)=

28+16=

44in.    The two rectangles are the same size, so they both have an equal area. Now we find the area of just the patio spot, W= (8-3)×2  L= (14-3)×2 W= 10 L= 22  A=32 in.

Now, we multiply by two, since we counted it twice, 64 in.

Finally, subtract 64 from the the sum of the two areas from the landscape rectangles,  88-64= 24 in.

kayden mixed two solutions together which causes a chemical reaction and the solution becomes warm. which statement best describes what has happened

A. energy has been transformed from one form to another

B. energy has been created, where it did not exist before

C. the chemicals energy of the solution had been described

D. more energy has been created than has been destroyed

Answers

The answer is B because before mixing the solution together nothing happened and it wasn’t warm, now that kayden mixed the solutions causing a chemical reaction making it to become warm. There for it will be B

According to law of conservation of energy, the statement  which best describes what has happened is that energy has been transformed from one form to another.

What is law of conservation of energy?

According to law of conservation of energy, it is evident that energy  is neither created nor destroyed rather it is restored at the end of a chemical reaction .

Law of conservation of mass and energy are related as mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of mass is widely used in field of chemistry, fluid dynamics.

Law needs to be modified in accordance with laws of quantum mechanics under the principle of mass and energy equivalence.This law was proposed by Julius Robert Mayer in the year 1812.

The least common multiple of 8 and 12 is 24

Explanation:

Find and list the multiples each number until the first common multiple is found.

This is the lowest common multiple .

Multiples of 8

Therefore,

LCM of 8 and 12 is 24

Answer: The answer is 24

Step-by-step explanation: One easy way to find least common multiples is to take the large number and multiply it by increasing numbers (1,2,3,etc.) until a number is found that is also divisible by the smaller number.

In this case, we can multiple 12 by increasing numbers until we find a number that is also divisible by 8.
