what is the area of the convince store

Answer:

  2184

Step-by-step explanation:

You want to know the possible number of ways 3 flavors can be chosen from 14 when order matters.

The number of permutations of 14 flavors taken 3 at a time is ...

  14 × 13 × 12 = 2184

There are 14 ways to choose the bottom flavor, then 13 ways to choose a different middle flavor, and finally 12 ways to choose a different top flavor. Each flavor can go with any combination of the others, so the total number is the product of 14·13·12, or 2184.

The formula for the number of n things taken k at a time is ...

  P(n, k) + n!/(n-k)!

For n=14, k=3, this is the product shown above.

A 60-inch piece is the shorter one. 180 inches long is the longer piece.

Step-by-step explanation:

L + S = 240

L = 3 S

L + S = 240 ( 3 S ) + S = 240 \s 4 S = 240 \s S = 60

L = 3 S L = 3 ( 60 )

The new perimeter will be 2 times larger then the old perimeter, if both dimensions of rectangle are doubled.

The length of a shape's outline is its perimeter. You must add the lengths of all four sides of a rectangle or square to determine its perimeter. In this instance, x represents the rectangle's length and y its width.

The figure's length is essentially revealed by the perimeter. Assume that the perimeter of a square with equal sides will be four times that square's sides. The perimeter of a circle, which is determined by its radius, is known as its circumference.

The new dimensions  of rectangle = 4mm and 9mm

The original dimension = 2mm and 4.5 mm

Perimeter of rectangle = P=2(l+w) = 2 (4.5 +2 ) = 13 mm

Perimeter of rectangle after doubled dimension = 2 (9 + 4) = 26

So, the new perimeter will be 2 times larger then the old perimeter

To determine whether Juakali can successfully save the document on the flash disk, you can calculate the total number of words in the document and compare it to the amount of free space on the flash disk.

First, calculate the total number of lines in the document by multiplying the number of pages by the number of lines per page:

Total number of lines = 123 pages * 70 lines/page

= 8610 lines

Next, calculate the number of lines with 14 words by multiplying the total number of lines by the proportion of lines with 14 words:

Number of lines with 14 words = 8610 lines * 36/70

= 4380 lines

Calculate the total number of words in the lines with 14 words by multiplying the number of lines by the number of words per line:

Total number of words in lines with 14 words = 4380 lines * 14 words/line

= 61320 words

Calculate the number of lines with 18 words by subtracting the number of lines with 14 words from the total number of lines:

Number of lines with 18 words = 8610 lines - 4380 lines

= 4230 lines

Calculate the total number of words in the lines with 18 words by multiplying the number of lines by the number of words per line:

Total number of words in lines with 18 words = 4230 lines * 18 words/line

= 76140 words

Finally, add the total number of words in the lines with 14 words and the total number of words in the lines with 18 words to find the total number of words in the document:

Total number of words = 61320 words + 76140 words

= 137,460 words

To determine whether Juakali can successfully save the document on the flash disk, you can compare the total number of words in the document to the amount of free space on the flash disk. Since the flash disk has 256 KB of free space and there are 137,460 words in the document, Juakali will not be able to save the document on the flash disk. This is because the document is larger than the amount of free space available on the flash disk.

The substance will weigh 9 pounds after  4.5123 hours.

Here it is given that every 3 hours the weight of the substance doubles.

At 12 noon it weighed 2 pounds. Hence we will consider the initial weight to be 2.

Let the weight after x hours be w(x)

Here it doubles in 3 hours, hence the growth rate is 100%

Since the growth rate is given, the equation for the growth rate will be

w(x) = w₀.eˣ

where x = no. of 3-hour spans.

Here

w₀ = 2

and w(x) is given 9

Hence,

2eˣ = 9

or, e²ˣ = 9/2

Taking log on both sides we get

loge²ˣ = ln(9/2)

or, 2xloge = ln(9/2)

Since loge = 1 we get

2x = log(9/2)

or, x = 1.5041

Hence they will become 9 pounds after

Answer: C

Step-by-step explanation:

pythagorean theorem : a^2 + b^2 = c^2

8^2 + 8^2 = x^2

64 + 64 = x^2

128 = x^2

x = sqrt(128) square root both sides

x = 8sqrt(2) simplified

Answer: c, [tex]8\sqrt{2}[/tex]

Step-by-step explanation:

     Since this is a right triangle, we will use the Pythagorean theorem to help us solve for x.

    Theorem:

a² + b² = c²

    Substitue values:

8² + 8² = c²

    To the power of 2:

64 + 64 = c²

    Addition:

128 = c²

   Square root both sides of the equation:

[tex]\sqrt{128}[/tex] = c

    Reflexive property and breaking up 128 into two factors:

c = [tex]\sqrt{64*2}[/tex]

    Square root of 64:

c = 8[tex]\sqrt{2}[/tex]

   So, x = 8[tex]\sqrt{2}[/tex]

What is an equation?

A mathematical statement is referred to as an equation when two expressions are connected by the equal sign. A mathematical equation serves as the connection between two expressions on each side of the sign. Usually, there is only one variable and an equal sign.

Equations can be categorized as identities or conditional equations. An identity holds true regardless of the value given to the variables. A conditional equation's variables can only have specific values that produce the truth.

An equation is created by joining two expressions with an equal sign. The solution to an equation is a number that may be used as the variable to generate a true number statement.

Here, we have

Answer:  The percent that the house's value is going up each year is given by the factor 1.04 - 1, which is 0.04. This represents a 4% increase in the value of the house each year.

ii) To find the value of the home in 15 years, you can substitute x = 15 into the equation to get:

A = 400,000 (1.04)^15

= 400,000 (1.7589)

= 700,356

Therefore, the value of the home in 15 years is $700,356.

iii) To find when the value of the home will double, you can set the value of A equal to 2*400,000 and solve for x:

2*400,000 = 400,000 (1.04)^x

2 = (1.04)^x

x = log(2)/log(1.04)

The pressure of 28 inches of mercury occurs about 6 miles from the eye of the hurricane. We get this from the given algebraic expression.

An expression is formed by variables, constants, and algebraic operations. Since the operation among them is an algebraic or arithmetic operation, it is said to be an algebraic expression.

It is given that the algebraic expression that relates the barometric pressure and the eye of the hurricane as

f(x) = 0.48 ln(x+2) + 27

Here x is the distance in miles from the eye of the hurricane.

f(x) is the pressure of the mercury in a barometer in inches

So, the required distance from the eye of the hurricane when the pressure of 28 inches of mercury in the meter is

(Here f(x) = 28)

f(x) = 0.48 ln(x+2) + 27

⇒ 28 = 0.48 ln(x+2) + 27

⇒ 0.48 ln(x+2) = 28 - 27

⇒ ln (x+2) = 1/0.48

⇒ ln(x+2) = 2.0833

Applying exponential base "e" on both sides, we get

(x+2) = [tex]e^{2.0833}[/tex]

⇒ x + 2 = 8.0309

⇒ x = 8.0309 - 2 = 6.0309

When the result is rounded to the nearest whole number, we get x = 6 miles.

Thus, for the pressure of 28 inches of mercury, the eye of the hurricane is 6 miles far from the barometer.

The probability that she earns more than $2750 in a given month is  one subtracted by the p-value of Z = 2750, hence:
