At a livestock market, one customer purchased 4 sheep and 2 cows for a total of $1660. Another customer purchased 3 sheep and 5 cows for a total of $2925. Create a system of equations and solve it with substitution or elimination, and find the price of a sheep, and the price of a cow.

Answers

Answer:

[tex]s \approx \$182.14[/tex]

[tex]c \approx \$435.72[/tex]

Step-by-step explanation:

Set up a system of equations, where s is the cost of a sheep and c is the cost of a cow:

[tex]4s + 2c = \$ 1660[/tex],  [tex]3s + 5c = \$ 2925[/tex]

First, isolate c in the first equation.

[tex]4s + 2c = \$ 1660[/tex]

[tex]2c = \$ 1660 - 4s[/tex]

[tex]c = \$ 840 - 2s[/tex]

Next, substitute this value into the second equation:

[tex]3s + 5c = \$2925[/tex]

[tex]3s + 5(\$840 - 2s) = \$2925[/tex]

and simplify.

[tex]3s + \$4200 - 10s = \$2925[/tex]

[tex]-7s = -\$1275[/tex]

[tex]7s = \$1275[/tex]

[tex]s \approx \$182.14[/tex]

Finally, plug this value into the first equation to get the value of c:

[tex]4(\$182.14) + 2c = \$1660[/tex]

[tex]2c = \$1600 - \$728.57[/tex]

[tex]c \approx \$435.72[/tex]

So, a sheep costs about $184.14, and a cow costs about $435.72.

The slope for the following question is = 4.

What is slope?Slope is used to describe the steepness of a line. The definition of slope is the rise of a line over the run of a line, or the change in the vertical direction (y) over the change in the horizontal direction (x). When one thinks of skiing down a hill or climbing up a mountain, the angle at which they are descending or ascending is the slope. Sometimes the slope can be fairly flat or very steep depending on what it is.The slope of an object indicates how steep it is. Slope knowledge is crucial for daily decision-making. For instance, understanding a roof's slope enables builders to determine whether specific construction materials are required for shingling projects. Since there must be sufficient grade for water to pass through the tile, slope is crucial in agriculture when tiling a field. Slope can also be calculated using elevation points on a GIS, a type of digital map that can highlight areas with sharp elevation changes in the ground.

acc to our question-

the two y's are 0 and 4 so its 0-4then the two x's are0 and one so its 0-10-4/0-1 is -4/-1 which when simplified the negatives cancel out leaving you with a positive 4

Jessica found that the perimeter of her kitchen table was 18 feet she found the area of her kitchen table to be 18 ft.² what are the links and width of Jessica‘s kitchen table 

Answers

The length and width of Jessica's kitchen table are 6 ft and 3 ft or 3ft and 6 ft.

According to the question,

We have the following information:

Jessica found that the perimeter of her kitchen table was 18 feet she found the area of her kitchen table to be 18 ft.²

Now, let's take the length of the table to x ft and the width of the table to be y ft.

So, we know that following formulas are used to find the perimeter and area of rectangle:

Perimeter = 2(length+width)

2(x+y) = 18 ...(1)

Area = length*width

xy = 18

x = 18/y

Putting this value of x in equation 1:

2(18/y+y) = 18

18/y + y = 9

([tex]y^{2}[/tex]+18) = 9y

[tex]y^{2}[/tex]-9y+18 = 0

[tex]y^{2}[/tex]-6y-3y+18 = 0

y(y-6)-3(y-6) = 0

(y-6)(y-3) = 0

y-6 = 0 and y-3 = 0

y = 6 ft and y = 3 ft

Now, putting this value of y in x = 18/y:

x = 18/6

x = 3 ft

x = 18/3

x = 6 ft

Hence, the length and width of Jessica's kitchen table are 6 ft and 3 ft or 3ft and 6 ft.

Answers

Area of a Circle

What is the area of the a circle?

The area of circle is equal to pi times square of its radius, i.e. πr². To find the area of circle we have to know the radius or diameter of the circle.

Let's find the area of the circle first;

radius = diameter / 2

radius = 5 / 2

radius = 2.5ft

The area of the circle is;

A = πr²

A = π * 5²

A = 25π

A = 78.54ft²

For every square foot, the glass cost $3, this implies that 3 * 78.54 will be the total cost to cover the window.

cost = 3 * 78.54 = $235.62

An assistant is in charge of ordering lunch for the monthly office meeting. For the first month, she orders five Falafel wraps, fifteen Turkey BLT sandwiches, and twenty hot Ham and Swiss paninis for a total of $260. The next month, she orders eight Falafel wraps, eighteen Turkey BLT sandwiches, and 14 hot Ham and Swiss paninis for a total of $263. For the third month, she orders twelve Falafel wraps, 16 Turkey BLT sandwiches, and twelve hot Ham and Swiss paninis for a total of $258. How much does each sandwich cost?

Answers

The cost of Falafel wraps is $5.5, the cost of Turkey BLT sandwiches is $7.5, and the cost of hot Ham and Swiss paninis is $6.

How much does each sandwich cost?

In order to determine the cost of each sandwich, we would assign variables to the cost of sandwiches ordered, and then translate the word problem into algebraic expression as follows:

Let the variable f represent the cost of Falafel wraps.Let the variable t represent the cost of Turkey BLT sandwiches. Let the variable h represent the cost of hot Ham and Swiss paninis.

Therefore, translating the word problem into an algebraic expression, we have the following;

For the first month ⇒   5f + 15t + 20h = 260      ......equation 1.

The next month     ⇒   8f + 18t + 14h = 263         ......equation 2.

For the third month ⇒ 12f + 16t + 12h = 258       ......equation 3.

Next, we would solve the system of algebraic expressions simultaneously.

Multiplying equation 1 by 12/5 and subtracting it from equation 3, we have:

6.25t - 24h = -366    ......equation 4.

Multiplying equation 2 by 5/8 and subtracting it from equation 1, we have:

3.75t + 11.25h = 95.625    ......equation 5.

Solving equation 4 and equation 5, we have:

Falafel wraps, f = $5.5

Turkey BLT sandwiches, t = $7.5

▪ Root of multiplicity 1 at x = -1
■ Root of multiplicity 2 at x = -2
▪y-intercept of (0, 128)

Answers

The polynomial function that has the degree of 5 is written as f(x) = 2x⁵ + 26x⁴ + 128x³ + 296x² + 320x + 128

Polynomial function:

The equations formed with variables, exponents and coefficients are known as the polynomial equations. And it can have different exponents, where the higher one is called the degree of the equation.

Given,

Here we have the following things,

Degree = 5

Root of multiplicity 2 is x = -4

Root of multiplicity 1 at x = -1

Root of multiplicity 2 at x = -2

y-intercept of (0, 128)

Here we need to find the polynomial equation of the function.

According to the given roots of multiplicity, we have the factors of the polynomials are,

=> (x + 4)² (x + 1) (x + 2)²

So, the general form of the polynomial function can be written as,

=> f(x) = A (x + 4)² (x + 1) (x + 2)²

In order to find the 5 degree polynomial function, we have to calculate the value of A.

To Find the value of A, we have to apply the y - intercept point on the equation then we get,

=> 128 = A (0 + 4)² (0 + 1) (0 + 2)²

=> 128 = A (4)² (1) (2)²

=> 128 = A (16 x 1 x 4)

=> 128 = 64A

=> A = 2

Now, the polynomial function is written as,

=> f(x) = 2 (x + 4)² (x + 1) (x + 2)²

When we expand this one then we get,

=> f(x) =2 [x⁵ + 13x⁴ + 64x³ + 148x² + 160x + 64]

Therefore, the resulting polynomial function is,

=> f(x) = 2x⁵ + 26x⁴ + 128x³ + 296x² + 320x + 128

How many cubic inches are in an aluminum can with a 2 3/5 diameter and 5 1/4 in height?

Answers

According to the volume of cylinder formula, an aluminum can with a 2 3/5 diameter and 5 1/4 in height are in 27.86 cubic inches.

Volume of Cylinder

The formula to calculate the volume of the cylinder is

Volume of a cylinder = πr²h cubic units.

where

r refers the radius

h refers the height.

Given,

Here we have an aluminum can with a 2 3/5 diameter and 5 1/4 in height and now we have to find the volume in cubic inches.

While we looking into the given question, we know the following values,

Diameter = 2 3/5

When we simplify it, then we get the value of diameter as

d = 13/5 or 2.6

Similarly, the value of height is rewritten as,

h = 5.25

So, based on the formula of volume of cylinder,

We get the value as,

=> V = π x (2.6/2)² x 5.25

Apply the value of π as 3.14, then we get,

=> V = 3.14 x (1.3)² x 5.25

=> V = 16.485 x 1.69

Therefore, the volume in cubic inches is 27.86 cubic inches.

Answer:

$262.50

Step-by-step explanation:

20 : 105 = 50 : x

x = (50 * 105)/20

x = (5 * 105)/2

x = 525/2

x = 262.50

Answer: $262.50

Step-by-step explanation:

What I did was divide the $105 by 20 and got $5.25. I then multiplied $5.25 by 50 since that's how many she's going to sell and got $262.50.

What are the zeros of the function f(x)=x²-x² - 2?

O +2, ti
O +√2 ti
O+√3, ti

Answers

The zeros of the function f(x) = x⁴− x² − 2 are  ±√2 or x = ±i option third positive or negative square root of 2,  ±i is correct.

What is a complex number?

It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.

We have a function:

f(x) =  x⁴− x² − 2

Assume u = x²

f(x) = u² - u - 2

(u + 1)(u - 2)

(x² + 1)(x² - 2)

x² = -1

x = √1

x² = 2

x = √2

x = ±√2  or  x² = -1 ⇒ x = ±i

Thus, the zeros of the function f(x) = x⁴− x² − 2 are  ±√2 or x = ±i option third positive or negative square root of 2,  ±i is correct.
