This relation is an inverse variation {(-1,8),(4,-2),(-2,4)} what equation represents this relation?

Answers

Answer 1

ANSWER

[tex]y = - \frac{8}{x} [/tex]

EXPLANATION

An inverse variation equation is of the form:

[tex]y = \frac{k}{x} [/tex]

We plug in the point (-1,8).

[tex] 8= \frac{k}{ - 1} [/tex]

This implies that k=-8

Therefore the inverse variation equation is :

[tex]y = - \frac{8}{x} [/tex]

Answer 2

Final answer:

The set of points {(-1,8),(4,-2),(-2,4)} represents an inverse variation with the equation xy = -8, as the product of x and y is consistently -8 for all given points.

Explanation:

An inverse variation can be defined by an equation of the form xy = k, where k is a nonzero constant. Given the set of points {(-1,8),(4,-2),(-2,4)}, we can find the constant k by multiplying the x-coordinate with the y-coordinate for each point, as follows:

(-1)(8) = -8

(4)(-2) = -8

(-2)(4) = -8

Since the product of x and y is consistent and equal to -8 across all points, we can confirm that k = -8 and thus the equation representing this relation is xy = -8.

What is the perimeter of a square with a side length of 5(2p + 3)?

Answers

Answer:

P = 40p + 60

Step-by-step explanation:

The formula of a perimeter of a square withe side a:

P = 4a

We have a = 5(2p + 3).

Substitute:

P = 4[5(2p + 3)]               use the distributive property

P = 4[(5)(2p) + (5)(3)] = 4(10p + 15) = (4)(10p) + (4)(15)

P = 40p + 60

what is the area of the figure:

Answers

For this case we have that the area of the triangle is given by:

Where:

b: It's the base

h: It's the height

We have to:

[tex]cos (45) = \frac {b} {24}\\b = 24 * cos (45)\\b = \frac {\sqrt {2}} {2} * 24\\b = 12 \sqrt {2}[/tex]

The atura will be given by:

[tex]sin (45) = \frac {h} {24}\\h = 24 * sin (45)\\h = \frac {\sqrt {2}} {2} * 24\\h = 12 \sqrt {2}[/tex]

So, the area is:

[tex]A = \frac {12 \sqrt {2} * 12 \sqrt {2}} {2}\\A=\frac{(12\sqrt{2})^2}{2}\\A = 144[/tex]

Answer:

144

Answer:

Area=144

Step-by-step explanation:

In right triangle ABC,

[tex]\sin\left(45^o\right)=\frac{BC}{AB}[/tex]

[tex]\frac{1}{\sqrt{2}}=\frac{BC}{24}[/tex]

[tex]\frac{1}{\sqrt{2}}=\frac{Height}{24}[/tex]

[tex]\frac{24}{\sqrt{2}}=Height[/tex]

[tex]Height=\frac{24}{\sqrt{2}}[/tex]

similarly

[tex]\cos\left(45^o\right)=\frac{AC}{AB}[/tex]

[tex]\frac{1}{\sqrt{2}}=\frac{AC}{24}[/tex]

[tex]\frac{1}{\sqrt{2}}=\frac{Base}{24}[/tex]

[tex]\frac{24}{\sqrt{2}}=Base[/tex]

[tex]Base=\frac{24}{\sqrt{2}}[/tex]

Then area of right triangle [tex]=\frac{1}{2}\left(Base\right)\left(Height\right)[/tex]

[tex]=\frac{1}{2}\left(\frac{24}{\sqrt{2}}\right)\left(\frac{24}{\sqrt{2}}\right)[/tex]

[tex]=\frac{576}{4}=144[/tex]

The regular price of a television set is $1,200. Albert buys the television set at a discount of 35% . How much does he pay for the television set?​

Answers

He pays $780 for the television set.

1200*.35=420

1200-420=780

Albert pays $780 for the television set after receiving a 35% discount on the original price of $1,200.

The regular price of a television set is $1,200. To calculate the price Albert would pay after receiving a 35% discount, you need to calculate the discount amount and subtract it from the original price. The discount can be calculated by multiplying the original price by the discount percentage.

Discount = Original Price × Discount Percentage = $1,200 ×0.35 = $420

Now subtract the discount from the original price:

Final Price = Original Price - Discount = $1,200 - $420 = $780

Therefore, Albert pays $780 for the television set.

Use the net as an aid to compute the surface area of the triangular prism. A) 550m^2 B) 614m^2 C) 670m^2 D) 790m^2

Answers

Answer:

The correct answer is option D.  790 m²

Step-by-step explanation:

Formula:-

Area of triangle = bh/2

Area of rectangle = bh

where b - Base and h - Height

To find the area of prism

Area of prism = Base area  + side rectangle area + side triangle area

 = (16 * 11)  + (2 * 11 * 17) + (2 * 16 * 15 /2)

 = 176 + 374 + 240

 = 790 m²

Therefore the correct answer is option D.  790 m²

The surface area of the triangular prism is 790m². ( option D)

A triangular prism is a type of prism with triangular base. The surface area of a prism is expressed as ;

SA = 2B + ph

where , B is the base area and p is the perimeter of the base.

Base area = 1/2bh

where b is the base and h is the height

= 1/2 × 16 × 15

= 8 × 15

= 120m²

Perimeter = 17 + 16 + 17 = 50m²

Surface area = 2 × 120 + 50 × 11

= 240 + 550

= 790 m²

Therefore, the surface area of the prism is 790m²

On a certain day, the temperature changed at a rate of -2 degrees Fahrenheit per hour. How long did it take for the change in temperature to be -14 degrees Fahrenheit

Answers

Answer:

7 hours.

Step-by-step explanation:

Pretty easy. 14 divided by 2. To check the answer, 2 x 7 = 14.

Final answer:

When the temperature change rate is -2 degrees Fahrenheit per hour, it takes 7 hours for the temperature to drop by -14 degrees Fahrenheit.

Explanation:

The question asks us to determine the time it took for the temperature to drop by -14 degrees Fahrenheit when the rate of temperature change was -2 degrees Fahrenheit per hour. This can be solved using a simple equation of rate × time = change in quantity. As the rate is -2 degrees Fahrenheit per hour and the total temperature drop is -14 degrees Fahrenheit, the equation becomes -2 × time = -14. To solve for time, divide the total temperature change by the rate of change. Substituting the values into the equation gives: time = -14 / -2. Thus, the time it took for the temperature to drop by -14 degrees Fahrenheit was 7 hours.

The lowest common denominator of the two fractions is 4 because it is the smallest number that both fractions can be transformed into. 3/2 is multiplied by 2 to create 6/4 which can be added to 11/4.

we could add the left-side and then cross-multiply and so on, OR we can simply get the LCD of all denominators, in this case 4,2 so our LCD will just be 4, and multiply both sides by 4, that way doing away with the denominators, so let's do so

Chef Katrina uses 1 cup of pecans for every 3 cups of peanuts in her Merry Munch Mix. One cup of pecans costs $ 4.99 and one cup of peanuts costs $2.25. If the cost for nuts in a batch of Merry Munch Mix is $35.22, how many cups of each type of nut were used?

Answers

Final answer:

Chef Katrina used 3 cups of pecans and 9 cups of peanuts for her Merry Munch Mix, totaling $35.22 based on the given prices of $4.99 per cup of pecans and $2.25 per cup of peanuts.

Explanation:

Calculating the Quantities of Pecans and Peanuts in the Merry Munch Mix

Chef Katrina uses a ratio of 1 cup of pecans to 3 cups of peanuts in her mix. We are given the cost per cup of pecans as $4.99 and the cost per cup of peanuts as $2.25. The total cost of nuts in the mix is $35.22.

To solve this, let's denote the number of cups of pecans used as p and the number of cups of peanuts as 3p (since there are three times as many peanuts as pecans). The total cost for pecans would be p times $4.99 and for peanuts 3p times $2.25.

Our equation based on the total cost is:
4.99p + 2.25(3p) = 35.22
4.99p + 6.75p = 35.22
11.74p = 35.22

Dividing both sides by 11.74 to solve for p:
p = 35.22 / 11.74
p = 3 cups of pecans

As there are three times more peanuts than pecans:
3p = 3 * 3 = 9 cups of peanuts

Therefore, Chef Katrina used 3 cups of pecans and 9 cups of peanuts in her Merry Munch Mix.

Campbell's is designing a new label for their soup cans that covers the entire side of the can The soup can has a height of 8 inches and a radius of 2.5 inches. Determine how much material is needed to create each label.

Answers

Answer:

When π is approximated, 125.68, or 40π

Step-by-step explanation:

Circumference formula is 2πr

This is approx: 15.71

Multiply that by 8 to find the surface area of the side of the can.

The answer is 125.68.

HOWEVER, if you are expressing this without approximating π,

it would be 5(Pi), then multiply by 8, and we would get 40π

So un-simplified is 40π

Final answer:

The amount of material needed to create each label for Campbell's soup cans is 40π square inches.

Explanation:

To determine the amount of material needed to create each label for Campbell's soup cans, we need to find the lateral surface area of the can. The lateral surface area is the area of the curved surface. Assuming the label covers the entire side of the can, we need to find the area of the curved surface which can be calculated using the formula:

Lateral Surface Area = 2 * π * radius * height

Substituting the given values, we have:

Lateral Surface Area = 2 * π * 2.5 * 8 = 40π square inches.

Answer:

27.5 square yards

Step-by-step explanation:

So, we have two shapes connected together and we want to know the combined area of the two.  All we have to do is find out the area of each one, then add the results.

First, the rectangle:

The area of a rectangle is the base multiplied by the height, so

A = 6 x 4 = 24 square yards

Then, the half-circle.

We know the area of a circle is calculated with A = π * r², so the area of a half circle will be A = (π * r²)/2.

We know the circle has a diameter of 3 yards because the wall next to it is also 3 yards and the whole structure is 6 yards wide, so...

A = (π (1.5)²)/2 = 2.25 π / 2 = 3.53 square yards

Overall, we have

Area of the rectangle: 24 square yards

Area of the half-circle: 3.53 square yards

Total: 27.53 square yards, rounded to the tenth: 27.5 square yards.

Answer:

27.5 yards^2

Step-by-step explanation:

We are given a figure which comprises of two shapes: a rectangle and a semicircle and we are to find the area of this composite figure.

We know that the area of these two shapes is given by the following formulas so we will put in the given values to get:

Area of rectangle = [tex]length \times width[/tex] = [tex]6 \times 4[/tex] = 24 yd^2

Area of semi-circle = [tex]\frac{\pi r^2}{2}[/tex] = [tex]\frac{3.14 \times 1.5^2}{2}[/tex] = 3.53 yd^2

Area of composite figure = [tex]24+3.53[/tex] = 27.5 yards^2

The length of a rectangle is 2 inches more than its width. The perimeter of the rectangle is 24 inches. The equation 2x + 2(x + 2) = 24, where x is the width in inches, represents this situation. The value of x from the set {1, 3, 5, 7} that holds true for the equation is . So, the width of the rectangle is inches and its length is inches.

Answers

Answer:

Width is 5 and length is 7

Step-by-step explanation:

You can solve the equation using the distributive property and inverse operations.

2x +2(x+2)=24

2x + 2x + 4 = 24

4x + 4 = 24

4x = 20

X = 5

This means the width is 5 and the length is 7.

Final answer:

The width of the rectangle is 5 inches and its length is 7 inches.

Explanation:

The given equation 2x + 2(x + 2) = 24 represents the situation with a rectangle's length being 2 inches more than its width and the perimeter of the rectangle being 24 inches. To find the value of x from the set {1, 3, 5, 7} that holds true for the equation, we can substitute each value into the equation and solve for x. By trying each value, we find that x = 5 holds true for the equation.

Therefore, the width of the rectangle is 5 inches and since the length is 2 inches more than the width, the length would be 7 inches.
