Answer:

17.27 miles aroundabout 23.75 square miles

Step-by-step explanation:

a) The circumference of the circle is given by ...

  C = πd

  C = (3.14)(5.5 mi) = 17.27 mi

The distance around the lake is about 17.27 miles.

__

b) The area is given by ...

  A = πr^2 . . . . . where r = d/2

  A = (3.14)(2.75^2) ≈ 23.75 . . . . square miles

The surface area of the lake is about 23.75 square miles.

_____

If you use a more exact value of pi (the "pi button" for example), then the hundredths digit increases by 1 in each case: 17.28, 23.76.

Answers

Answer:

radius: 3 units <----> Circumference: 18.84 units

Diameter: 12 units <----> Circumference: 37.68 units

Diameter: 36 units <----> Circumference: 113.04 units

Radios: 5 unites <----> Circumference: 31.4 units

Step-by-step explanation:

How I got the answers for the radiuses:

3 (this is only half the diameter so if you do 3 x 2 you will get the diameter.)

3 x 2 = 6

C = pi x d

C = 3.14 x 6

C = 18.84 [this is the first radios]

5 (this is only half the diameter so if you do 5 x 2 you will get the diameter.)

5 x 2 = 10

C = pi x d

C = 3.14 x 10

C = 31.4 [this is the second radios]

How I got the diameters:

12 (this is the full diameter so we do not have to multiply it by 2)

C = pi x d

C = 3.14 x 12

C = 37.68 [this is the first Diameter]

36 (this is the full diameter so we do not have to multiply it by 2)

C = pi x d

C = 3.14 x 36

C = 113.04 [this is the second Diameter]

Orchid wants to retile her bathroom floor, which has an area of 40 square feet. She is deciding between two types of custom tiles. The square tile is One-half foot by One-half foot and costs $0.45 per tile. The rectangular tile is 2 feet by One-fourth foot and costs $0.80 per tile.

Answers

Answer:

b. She should choose the rectangular tiles because the total cost will be $8 less.

Step-by-step explanation:

Which tile should Orchid choose to minimize costs? Explain.

a. She should choose the square tiles because the total cost will be $8 less.

b. She should choose the rectangular tiles because the total cost will be $8 less.

c. She should choose the square tiles because the total cost will be $14 less.

d. She should choose the rectangular tiles because the total cost will be $14 less.

Area of a square tile = 1/2 × 1/2

= 1/4

= 0.25 square feet

Area of rectangular tile = 2 × 1/4

= 2/4

= 0.5 square feet

Number of square tile needed = Area of the bathroom floor / Area of the square tile

= 40 square feet / 0.25 square feet

= 160

Number of square tile needed = 160

Cost of square tile needed = number of tiles × cost per tile

= 160 × $0.45

= $72

Cost of square tile needed = $72

Number of rectangular tile needed = Area of the bathroom floor / Area of the rectangular tile

= 40 square feet / 0.5 square feet

= 80

Number of rectangular tile needed = 80

Cost of rectangular tile needed = number of tiles × cost per tile

= 80 × $0.80

= $64

Cost of rectangular tile needed = $64

Cost of square tile needed = $72

Cost of rectangular tile needed = $64

20 meters
25 meters
50 meters
250 meters

Answers

Answer: 20 meters  

Step-by-step explanation:

We are told that an oblique cylinder has a radius of 16 meters and a volume of 5,120 pi cubic meters.      We will use volume of oblique cylinder to find the height of our given cylinder.      volume of a oblique cylinder= πr²hUpon substituting our given values in above formula we will get,

5,120π m³ = π ( 16 m² × h )

5,120π m³ = π × 256 m² × h  

 Let us divide both sides of our equation by 100 pi.

Therefore, height of our given oblique cylinder is 20 meters.

For 15 points.Explain, in your own words, the steps necessary to solve a system of equations
using the substitution method.

Answers

★ Required Answer:-

First, what is an equation?

➳ A mathematical statement which shows that two algebraic expressions are equal is called and equation.

Or, LHS = RHS

Example:- 3x - 5 = x + 8

An equation is said to be a linear equation if it contains only one variable (literal) with highest power 1.

_______________________

Solving an equation:-

To solve the equation x + 5 = 7 means to find the value of an unknown algebraic quantity used in the equation.

Example:-

To solve the equation x + 5 = 7 means to find the value of x.To solve the equation 3y + 2 = 9 means to find the value of y.To solve the equation [tex]\sf \dfrac{2a}{3} + 4 = 10[/tex] means to find the value of a ⠀⠀⠀⠀⠀⠀and so on!

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Rules for solving an equation by the substitution method:-

Rule ❶ 

If x = 2, the value of the expression 3x + 2 = 3 × 2 + 2 = 6 + 2 = 8

Rule

If x = 0, the value of the expression 3x + 2 = 3 × 0 + 2 = 0 + 2 = 2

Rule ❸ 

If x = -2, the value of the expression 3x + 2 = 3 × -2 + 2 = -6 + 2 = -4

Now consider the algebraic expression 5x - 2y

This expression consists of variables x and y.

Now if :-

x = 3 and y = 2, 5x - 2y = 5 × 3 2 × 2 = 15 - 4 = 11x = 8 and y = 5, 5x - 2y = 5 × 8 - 2 × 5 = 40 - 10 = 30

⠀⠀⠀⠀⠀⠀⠀⠀

The process of finding the value of an algebraic expression by substituting the given value of its variable is called substitution.⠀⠀

Callie posted a cute cat video on a popular website. On the first day after she posted the video, the video had 5 views. On the second day, it had 15 views. On the third day, it had 45 views, and on the fourth day, it had 135 views.
A. How many views would you expect the video to have after 5 days? Explain how you found your answer.



B. Which type of reasoning did you use to solve this problem, deductive or inductive? (2 points)

Answers

Answer:

(A) 5th day: 405 views

(B) inductive

Step-by-step explanation:

Each day the views get multiplied by 3.

Answer:

A. I would expect the video to have 405 views after day 5. There is a pattern of the number being multiplied by 3.

B. Deductive reasoning

Step-by-step explanation:

(This is really going to explain BOTH questions at the same time)

Looking that the problem, the number of views keep going up. There is a multiplier behind this, we just don't know WHAT multiplier it would be. To find that out, divide 1 value by the one before it. I'll do 135 divided by 45 as an example. That would equal three. Now we know the multiplier is 3. So, now we need to multiply 135 by 3 to get 405 views after five days.

Mixed number is the combination of the whole number and the fraction number. The whole and the part of the whole combined can be expressed as a mixed numbers. the result of the division of the two mixed number is [tex]3\dfrac{3}{16}[/tex].

Given information;

The mixed numbers given is the problem are  [tex]8\dfrac{1}{3} [/tex]  and [tex]2\dfrac{2}{3} [/tex]

Mixed number

Mixed number is the combination of the whole number and the fraction number. The whole and the part of the whole combined can be expressed as a mixed numbers.

Now the given mixed number has to be divided. This number can be divided by converting into the proper fraction numbers. Let I is the result when the two numbers are divided. Thus,

[tex]x=8\dfrac{1}{2} \div 2\dfrac{2}{3} \\ [/tex]

To solve this convert the mixed numbers into the fraction number. For this multiply the denominator to the whole number and then add in the numerator. Thus,

[tex]x=\dfrac{16+1}{2} \div \dfrac{6+2}{3} \\ x=\dfrac{17}{2} \div \dfrac{8}{3} \\ [/tex]

Convert the divide sign into the multiply sign by changing the numerator to the denominator of one of the fraction.

[tex]x=\dfrac{17}{2}\times \dfrac{3}{8} \\ x=\dfrac{51}{16}\\[/tex]

As 16 can divide the number 51 in 3 times with reminder 3. Thus the mixed number for the above fraction can be written as,

[tex]x=3\dfrac{3}{16}[/tex]

Thus the result of the division of the two mixed number is [tex]3\dfrac{3}{16}[/tex].

Answers

Answer:

C

Step-by-step explanation:

Using the Central Limit Theorem, it is found that the option in which is it not appropriate to assume that the sampling distribution of the sample mean is approximately normal is:

C) A random sample of 10 taken from a population distribution that is skewed to the right

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In option C, there is an skewed variable and a sample size less than 30, hence, the Central Limit Theorem is not applicable.
