As a result of this, 20,160 different words can be made from the letters inside the word multiply.

There are three distinct sorts, classes, groups, and categories. The two plants are very different from one another (from one another). Every herb has a unique flavor. The phrase can signify one of three things.

The word MULTIPLY has 8 letters. To find the number of distinct words that can be formed, we can use the formula for permutations with repeated elements:

n!/(n1!n2!...nk!)

where n is the total number of items, and n1, n2, ..., nk are the numbers of times each item is repeated.

In this case, there are 8 letters, but the letter L appears twice. So we have:

n = 8

n1 = 2 (for the L's)

n2 = n3 = ... = nk = 1 (for the other letters)

Substituting into the formula, we get:

8!/(2!1!1!1!1!1!1!) = 8×7×6×5×4×3 = 20160

Explanation:

The plan outlined here makes nearly best use of available resources and job constraints. It results in job completion in about 12 weeks, or 3 months.

__

For simplicity, we choose to work 5 hours per day, 5 days a week. Each skilled volunteer will complete their weekly 10 hours by working 2 days. Each unskilled volunteer will complete their 15 hours by working 3 days. Some volunteers will work an "interrupted" schedule that consists of non-consecutive work days. The purpose of this is to provide compliance with job site limitations, volunteer hour limitations, and to maximize continuity of communication as the job progresses.

A weekly schedule along these lines is shown in the attachment. It has 2 skilled volunteers and 6 or 7 unskilled volunteers on site each day. The ratio of skilled to unskilled volunteers is 31% : 69%. Each works the maximum number of hours for their skill level.

The net result is that 50 skilled hours and 165 unskilled hours are worked each week.

__

We assume the wording "three times as many unskilled volunteers are required to complete any job compared to skilled volunteers" means that 3 unskilled hours are equivalent to 1 skilled hour. (An alternative interpretation is that 45 hours of unskilled labor is equivalent to 10 hours of skilled labor.)

Using this assumption, job completion occurs at the equivalent rate of ...

  50 +165/3 = 105 . . . equivalent skilled hours per week

The total job requirement of 1200 skilled hours can be met in 12 weeks' time, well within the 6-month desired completion period. (Even using the alternate interpretation of labor equivalent, the job can be done in 14 weeks.)

__

In any given week, the 5 skilled volunteers are designated s1–s5, and the 11 unskilled volunteers are u1–u11. The days they're scheduled to work are identified by the weekday labels M, T, W, T, F. Skilled volunteer s1 works only Monday and Friday, and is responsible for week-to-week tie-in. Unskilled volunteers u2, u4, u7, u9 get two (2) days off in the middle of each week.

No, Etsuko is not correct. The length of the larger paper is 17.9 cm greater than the length of the smaller paper.

The smaller paper has a side length of 7.5 cm. The larger paper has a side length of 25.4 cm.

The difference between the two side lengths is 25.4 cm - 7.5 cm = 17.9 cm.

Therefore, the length of the larger paper is 17.9 cm greater than the length of the smaller paper.

This takes into account the fact that each of the angles has an opposite ray on its other side in addition to the common side they share.

When two rays are linked at their ends, they create an angle in geometry. The sides or arms of the angle are what are known as these rays.

When two lines meet at a point, an angle is created.

An "angle" is the measurement of the "pening" between these two rays. It is symbolized by the character. The circularity or rotation of an angle is often measured in degrees and radians.

Angles are a common occurrence in daily life.

The slope of the line through (-2,3) and (1,-3) is -2.

Y = mx + b, where m is the line's slope and b is the y-intercept, is the slope-intercept form of a linear equation (the point where the line intersects the y-axis). This form is helpful because, given a line's equation, it enables us to quickly determine the slope and y-intercept. By charting the y-intercept and utilising the slope to identify additional points on the line, we can also use this technique to graph a line. We can also create an equation for a line given its slope and y-intercept using this approach.

The slope of the line is given as:

slope = (y2 - y1) / (x2 - x1)

Substituting the value of the given coordinates we have:

slope = (-3 - 3) / (1 - (-2))

slope = -6 / 3

slope = -2

Hence, the slope of the line through (-2,3) and (1,-3) is -2.

Answer:

What does this even mean????

Step-by-step explanation:

this is just a bunch of random letters.

Answer:

a) Number of projects in the first year = 90

b) Earnings in the twelfth year = $116500

Total money earned in 12 years = $969000

Step-by-step explanation:

Given that:

Number of projects done in fourth year = 129

Number of projects done in tenth year = 207

There is a fixed increase every year.

a) To find:

Number of projects done in the first year.

This problem is nothing but a case of arithmetic progression.

Let the first term i.e. number of projects done in first year = \(a\)

Given that:

\(a_4=129\\a_{10}=207\)

Formula for \(n^{th}\) term of an Arithmetic Progression is given as:

\(a_n=a+(n-1)d\)

Where \(d\) will represent the number of projects increased every year.

and \(n\) is the year number.

\(a_4=129=a+(4-1)d \\\Rightarrow 129=a+3d .....(1)\\a_{10}=207=a+(10-1)d \\\Rightarrow 207=a+9d .....(2)\)

Subtracting (2) from (1):

\(78 = 6d\\\Rightarrow d =13\)

By equation (1):

\(129 =a+3\times 13\\\Rightarrow a =129-39\\\Rightarrow a =90\)

Number of projects in the first year = 90

b)

Number of projects in the twelfth year =

\(a_{12} = a+11d\\\Rightarrow a_{12} = 90+11\times 13 =233\)

Each project pays $500

Earnings in the twelfth year = 233 \(\times\) 500 = $116500

Sum of an AP is given as:

\(S_n=\dfrac{n}{2}(2a+(n-1)d)\\\Rightarrow S_{12}=\dfrac{12}{2}(2\times 90+(12-1)\times 13)\\\Rightarrow S_{12}=6\times 323\\\Rightarrow S_{12}=1938\)

It gives us the total number of projects done in 12 years = 1938

Total money earned in 12 years = 500 \(\times\) 1938 = $969000

The measure of angle c is 70 degrees.

If angle a and angle b are complementary, it means that the sum of their measures is equal to 90 degrees.

Given:

Measure of angle a = 10x + 10

Measure of angle b = 20

We can set up the equation:

(10x + 10) + 20 = 90

Simplifying the equation:

10x + 30 = 90

Subtracting 30 from both sides:

10x = 60

Dividing both sides by 10:

x = 6

Now, we have found the value of x to be 6.

To find the measure of angle c, we can substitute the value of x into the equation for angle a:

Measure of angle a = 10x + 10

Measure of angle a = 10(6) + 10

Measure of angle a = 60 + 10

Measure of angle a = 70

As a result, angle c has a measure of 70 degrees.

Answer:

Step-by-step explanation:

When we have two similar triangles, we can use a proportion to determine an unknown value.

\(\frac{2x + 80}{87} = \frac{80}{60}\)

We will cross multiply to get two equivalent equations that can be solved.

(2x + 80) x 60 = 120x + 4800

We can simplify this by dividing both sides by 24 to get a much simpler equation to work with: 5x + 200.

80 x 87 = 6960

We will also divide this by 24. The answer is 290

5x + 200 = 290

Subtract 200

5x = 90

Divide by 5

x = 18

Now, we can also check to make sure we did everything correctly.

(2(18) + 80) x 60 = 120x + 4800

(36 + 80) x 60 = 120(18) + 4800

Answer:

x² + (y + 3)² = 25

Step-by-step explanation:

the centre (C) of the circle is at the midpoint of the diameter.

using the midpoint formula

midpoint = ( \(\frac{x_{1}+x_{2} }{2}\) , \(\frac{y_{1}+y_{2} }{2}\) )

with (x₁, y₁ ) = P (3, 1 ) and (x₂, y₂ ) = Q (- 3, - 7 )

C = ( \(\frac{3-3}{2}\) , \(\frac{1-7}{2}\) ) = ( \(\frac{0}{2}\) , \(\frac{-6}{2}\) ) = (0, - 3 )

the radius r is the distance from the centre to either P or Q

using the distance formula

r = \(\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }\)

with (x₁, y₁ ) = C (0, - 3 ) and (x₂, y₂ ) = P (3, 1 )

r = \(\sqrt{(3-0)^2+(1-(-3)^2}\)  

 = \(\sqrt{3^2+(1+3)^2}\)

 = \(\sqrt{3^2+4^2}\)

 = \(\sqrt{9+16}\)

 = \(\sqrt{25}\)

 = 5

the equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k ) are the coordinates of the centre and r is the radius

here (h, k ) = (0, - 3 ) and r = 5 , then

(x - 0 )² + (y - (- 3) )² = 5² , that is
