Of the animals on a farm 60% are cows and the rest are sheep. When 260 more cows and sheep are added to the farm, the percent of cows increases by 20% and the number of sheep doubles. Find the number of sheep originally on the farm.

Answers

Answer 1

The number of sheep originally on the farm will be equal to 200.

What is the Percentage?

The Latin phrase "per centum," which means "by the hundred," is where the English word "percentage" comes from.

Percentage segments are those with a numerator of 100. In other words, it is a connection where the whole is always deemed to be valued 100.

As per the given information in the question,

Let the number of animals originally at the farm is x.

60% of the animals are cows.

So, 0.6x are cows.

If there are 60% cows, then there are 40% of sheep.

So, 0.4x are sheep.

The quantity of sheep multiplies when many cows and sheep were introduced to the property.

As a result, the farm now has the same amount of sheep that it did before.

Number of sheep added = 0.4x

There are total 260 animals added to the farm.

So,

Number of sheep added = 260-0.4x

Total number of animals = x + 260

The percentage of cows increased to 20%.

Initial number of cows at farm + cows added = Initial number of cows at farm + 20% of the total cows initially at the farm.

0.6x + (260-0.4x) = 0.6x + 0.2(0.6x)

0.6x+260-0.4x = 0.6x+0.12x

0.2x+260 = 0.6x+0.12x

0.2x+260 = 0.72x

260 = 0.52x

x = 260/0.52

x = 500

Thus, the farm's initial animal population was 500.

0.6x = the amount of cows that were first on the farm= 0.6(500) = 300 cows

0.4x = the amount of sheep that were initially on the farm = 0.4(500) = 200 sheep

0.4x = Sheep added = 200

christopher is working two summer jobs, making $7 per hour babysitting and making $10 per hour washing cars. in a given week, he can work no more than 16 total hours and must earn a minimum of $130. if xx represents the number of hours babysitting and yy represents the number of hours washing cars, write and solve a system of inequalities graphically and determine one possible solution.

Answers

Christopher can work average 9 hours babysitting and 7 hours washing cars in a given week to meet the minimum wage requirement and not exceed the maximum hours he can work.

Christopher is working two summer jobs and has a maximum of 16 hours to work in a given week. He is making $7 per hour babysitting and $10 per hour washing cars. To meet the minimum wage requirement of $130, he needs to make a total of $130 in a week. We can represent this using a system of inequalities. The first inequality is 7xx + 10yy ≥ 130, which means that the total wages (7 times the hours babysitting plus 10 times the hours washing cars) must be greater than or equal to $130. The second inequality is xx + yy ≤ 16, which means that the total hours (babysitting plus washing cars) must be less than or equal to 16. Graphically, we can solve this system of inequalities to find the possible solutions. One possible solution is x = 9 and y = 7, meaning Christopher can work 9 hours babysitting and 7 hours washing cars in a given week to meet the minimum wage requirement and not exceed the maximum hours he can work.

Graphically:

7xx + 10yy ≥ 130

xx + yy ≤ 16

7xx + 10yy = 130

xx + yy = 16

Therefore, the solution is x = 9 and y = 7.

Emilio buys liter bottles of shampoo when the store has the promotion shown. Write an expression in two different ways to represent the total cost 0f 3 liters of shampoo. Let L be the regular price of a liter bottle.

Answers

The expressions for the total costs are 2L + 0.7L  and 2.7L

How to determine the expression for the total cost?

From the question, we have the following parameters that can be used in our computation:

Number of litres = 3

Regular price = L

Discount = 30%

This means that there is a discount on the third item

So, we have the following expression

Total amount = 2 * L + L * (1 - discount)

Substitute the known values in the above equation, so, we have the following representation

Total amount = 2 * L + L * (1 - 30%)

Total amount = 2 * L + L * 0.7

This gives

Total amount = 2L + 0.7L

Evaluate the sum

Total amount = 2.7L

Hence, the expression is 2.7L

Empirical Rule 06
IQ scores can be described using a Normal distribution with a mean of 100 and a standard deviation of 15.
Using the Empirical '68-95-99.7' Rule, what percent of IQ scores are above 130?

Answers

Answer:

The Empirical Rule, also known as the 68-95-99.7 rule, states that for a normal distribution, approximately 68% of the data lies within one standard deviation of the mean, 95% lies within two standard deviations, and 99.7% lies within three standard deviations.

In this case, the mean is 100 and the standard deviation is 15, so approximately 95% of the data lies within two standard deviations of the mean. Since two standard deviations of 100 is 30 (15 * 2), this means that approximately 95% of the data lies within the range of 70 to 130. Therefore, approximately 5% of the data lies outside of this range, with 2.5% lying below 70 and 2.5% lying above 130.

Therefore, the percent of IQ scores that are above 130 is approximately 2.5%.

2. A local manufacturing firm produces four different metal products, each of which must be machined, polished and assembled. the specific times requirements ( in hours) for each products are as follows

Machining hours Polishing hours Assembling hours
Product I 3 1 2
Product II 2 1 1
Product III 2 2 2
Pruduct IV 4 3 1

Answers

Step-by-step explanation:

To find the total time required to produce each product, we can add up the machining, polishing, and assembling hours for each product. For example, for Product I, the total time required would be:

Total time for Product I = 3 hours + 1 hour + 2 hours = 6 hours

We can do this for each product to find the total time required for all four products:

Total time for Product I = 3 hours + 1 hour + 2 hours = 6 hours

Total time for Product II = 2 hours + 1 hour + 1 hour = 4 hours

Total time for Product III = 2 hours + 2 hours + 2 hours = 6 hours

Total time for Product IV = 4 hours + 3 hours + 1 hour = 8 hours

So, the total time required to produce all four products is 6 hours + 4 hours + 6 hours + 8 hours = 24 hours.

Answer:

In an arithmetic sequence, each term is obtained by adding the common difference to the previous term. In this case, the common difference is 3, so the formula for the nth term of the sequence can be written as:

a^n = a^1 + (n-1) * d

where a^1 is the first term of the sequence, and d is the common difference.

Since the first term of the sequence is -25 and the common difference is 3, we can plug these values into the formula to find the 30th term of the sequence:

a^30 = (-25) + (30-1) * 3

= (-25) + 29 * 3

= (-25) + 87

= 62

Therefore, the 30th term of the sequence is 62.

Step-by-step explanation:

Total angle in a triangle: 180°

∠N° = x°

∠M° = ( 2x - 3 )°

∠L° = ( 7x - 7 )°

180 = N + M + L

180 = x + 2x - 3 + 7x - 7

180 = 10x - 10

10x = 180 + 10

10x = 190

Divide both side by 10

x = 19

∠N° = x° = 19°

∠M° = ( 2x - 3 )° = ( 2(19) - 3 )° = 35°

∠L° = ( 7x - 7 )° = ( 7(19) - 7 )° = 126°

General indefinite integral

An integral is considered to be indefinite if it has no upper or lower bounds.

The most generic anti-derivative of f(x) is known as an indefinite integral and denoted, in mathematics, by F(x), which is any anti-derivative of f(x).

f(x) dx = F(x) + C

The integral of [tex]e^{x}[/tex] = [tex]e^{x}[/tex]

so ∫[tex]e^{x}[/tex] dx = [tex]e^{x}[/tex] + C

The integral of 1/8x = 1/4x,

so ∫1/8x dx = 1/4x + C

To find the integral of ([tex]e^{x}[/tex] + 1/8x), add the integrals of each term:

A contractor is building a new house and wants to determine the size of its foundation. The length of the
foundation is 6 feet more than 2 times its width. The value of the area of the foundation (in square feet)
is 1046 more than the value of the perimeter of the foundation (in feet). Which of the following values
are correct? Show work.

A. Area: 1196 sq ft
B. Worth: 23 ft
C. Perimeter: 150 ft
D. Length 29 ft

Answers

Answer:

  A, B, C

Step-by-step explanation:

You want to find the dimensions, perimeter, and area of a foundation such that the length is 6 feet more than twice the width, and the area is 1046 more that the value of the perimeter.

Setup

We can let x and y represent the length and width, respectively. Then the given relations translate to the equation ...

  A = LW . . . . . . . area formula

  P = 2(L +W) . . . . perimeter formula

  y = 2x +6 . . . . . relation between dimensions

  xy = 2(x +y) +1046 . . . . . relation between perimeter and area

Solution

Using the first equation to substitute for y, we have ...

  x(2x +6) = 2(x +(2x +6)) +1046

  2x² +6x = 6x +1058 . . . . . . . . . . . . eliminate parentheses

  x² = 529 . . . . . . . . . . . . . subtract 6x and divide by 2

  x = √529 = 23 . . . . . . . . . width; matches B

  y = 2(23) +6 = 52 . . . . length

  area = (23)(52) = 1196 . . . area; matches A

  perimeter = 2(23 +52) = 2(75) = 150 . . . . matches C

The area is 1196 square feet. (A)

The width is 23 feet. (B)

The perimeter is 150 feet. (C)

Suppose you are designing and conducting a poll to see which of the Congressional candidates are popular in your area. Use the terminology and concepts that we are learning in Lesson 1 - population, sample, sampling methods, representative sample, and presentation of data....
1. Discuss the following in your own words :
the population that you are trying to predict,
where and how are you selecting your sample,
what sampling method would you use,
how would you assure that you are selecting a representative sample, and
show an example of how you would present your data.

Answers

The population we're trying to predict is the population that is going to be Voters in our area, the where should probably be well as above our area, and the how now, generally speaking, we want to do a simple, random, or a random sample of some sort, random sample.

For instance, what you could do would be something like choose: random addresses in the area and send a survey, but sending a survey could introduce self-selection bias. So it would be ideal to visit in person basically and ask a few questions making sure the representative sample or how to ensure that we're getting a representative sample would be to, for instance, filter the random results and make sure that we have an even distance.

Ensure that there's an equal number within each quadrant of the town, basically split up the town.  Split towns into regions of populations or population densities and make sure we get the same proportion from each region.  However, we end up splitting the town into different regions. We show the proportion or show who is the most popular candidate in each 1 of the regions, so it could be something like this. That was supposed to be an alternative to a bar graph. The number of results for each different candidate depends on whether or not there's a sort of well-defined districts or areas in the town, but most sorts of relatively large cities have things like that. So the idea would be to represent not just the location, but also the information that you gain separately.

Split up the town so that there are an equal amount in each of its four quadrants. Make sure we receive the same proportion from each region by dividing towns into population or population density regions. But ultimately, we divide the town into many parts. It might look something like this since we display the percentage or the candidate who is most supported in each location. That was meant to be a bar graph substitute. Whether or not a town has clearly defined districts or areas affects the amount of results for each candidate, although this is true of most types of moderately large cities.

find $m\angle1$ .two triangles a b c and q r s are drawn. angles b and q are labeled with a single arc. angles a and s are marked with a double arc. angles a and b are labeled 45 degrees and 80 degrees respectively. angle r is labeled 1.

Answers

The measure of angle 1, m∠1, found using the congruency of the angles and the angle sum property of a triangle is 55°

What is the angle sum property of a triangle?

The angle sum property of a triangle specifies that the sum of the interior angles of a triangle is 180°

Please find attached the presentation of the details of the question as a drawing of the triangles created with MS Word

The parameters of the question are;

The number of arcs on angles b and q = Single arcs

Therefore, based on the arc markings indicating congruency of the angles, we get;

Angle b is congruent to angle q ∠b ≅ ∠q

Therefore, ∠b = ∠q, by the definition of congruency

The number of arcs on angle a and angle s = Double arcs

Therefore, angle a is congruent to angle s based on the arc markings, which indicates;

∠a ≅ ∠s
∠a = ∠s by the definition of congruency

The label on angle ∠a = 45°

The label on angle ∠b = 80°

∠a = ∠s, therefore, ∠s = 45°, by substitution property

∠b = ∠q, therefore, ∠q = 80° by substitution

∠s + ∠q + ∠1 = 180° Angle sum property of a triangle

45° + 80° + m∠1 = 180°

m∠1 = 180° - (45° + 80°) = 55°

what is the square root of 81

Answers

The square root of 81 is 9

Answer: I hope this is helpful

Step-by-step explanation:

The square root of 81 is 9 and you can say -9

We can find the square root of 81 using prime factorization method, or repeated subtraction method.

81 is a perfect square number and it is the fourth power of 3. we will calculate the square root of 81 by repeated subtraction method and solve a few interesting problems.Square Root of 81: √81 = 9

The square root of a number is the number that when multiplied to itself gives the original number as the product. Finding the square root of a number is the inverse of squaring a number. 81 = a × a = a2 Thus, a = √81= √(9 × 9)9 × 9 = 81 or -9 × -9 = 81. Therefore √81= ± 9This shows that 81 is a perfect square.

one period of a sine function or cosine function is called one amplitude incorrect: your answer is incorrect. of the sine curve or cosine curve.

Answers

The correct answer is cycle. A sine or a cosine function represent periodic functions where the value of the function is repeats after a definite interval.

What do you mean by periodic function?

A periodic function can be defined as:

A function returning to the same value at regular intervals. Though periodic motion and oscillatory motion sound the same, not all periodic motions will be oscillatory motion.

Image result for periodic function

If a function has a repeating pattern like sine or cosine, it is called a periodic function. The period is the length of the smallest interval that contains exactly one copy of the repeating pattern.

A motion that repeats itself at regular intervals is termed periodic motion. 1. A motion that does not repeat itself at regular intervals is termed non-periodic motion. 2. After a certain period of time, an object exhibiting periodic motion returns to its original position.
