Answer 1

Answer:

x=6 ; y=1

Step-by-step explanation:

Let 'y' stand for the speed of the wind and 'x' stand for the speed of Santa. We will use the general equation (distance)=(rate)(time) to write two equations from the given information:

With the wind:

35=(x+y)(5)

Against the wind:

35=(x-y)(7)

Now we have two equations and two unknowns so we can solve for x and y. We get:

x=6 miles/min

y=1 miles/min

Rearrange the equation so X is the independent variable. 6x+y=4x+11
Y=______________

Answers

6x+y=4x+11

y=4x+11-6x

y=-2x+11

[tex]\(y = 11 - 2x\)[/tex] is the rearranged equation with [tex]\(x\)[/tex] as the independent variable.

To rearrange the equation [tex]\(6x + y = 4x + 11\)[/tex] so that (x\) is the independent variable and (y) is dependent, we need to isolate (y) on one side of the equation.

Start with the given equation: [tex]\(6x + y = 4x + 11\)[/tex].

Subtract (4x) from both sides to move all terms involving (y) to one side: [tex]\(6x - 4x + y = 11\).[/tex]

Simplify the left side by combining like terms: 2x + y = 11.

To isolate y, subtract 2x from both sides: 2x + y - 2x = 11 - 2x.

Simplify: [tex]\(y = 11 - 2x\)[/tex].

So, the rearranged equation with (x) as the independent variable is y = 11 - 2x.

Detailed calculation:

Starting equation: (6x + y = 4x + 11)

Subtract (4x) from both sides:

[tex]\(6x - 4x + y = 4x - 4x + 11\)[/tex]

[tex]\(2x + y = 11\)[/tex]

Subtract (2x) from both sides:

[tex]\(2x + y - 2x = 11 - 2x\)[/tex]

[tex]\(y = 11 - 2x\)[/tex]

Therefore, [tex]\(y = 11 - 2x\)[/tex] is the rearranged equation with [tex]\(x\)[/tex] as the independent variable.

The area of a rectangular dog pen is 8 1/2 square feet.if the width is 3 2/5 feet,what's is the length,in feet ?

Answers

Answer:

l = 2.5 feet

Step-by-step explanation:

A = lb

8.5 = l * 3 2/5

8.5 = l * 3.4

l = 8.5 / 3.4

l = 2.5 feet (Always remember to put the units, otherwise you may not get points.)


Please give a rating and a thanks.


Thank you.

Answer:

l = 2 1/2 ft

Step-by-step explanation:

Area is given by the formula

A = l*w

We know the area is 8 1/2  

Changing this to an improper fraction  8 1/2 = (2*8 +1)/2 = 17/2

The width is 3 2/5  as an improper fraction  = (5*3+2)/5 = 17/5

A = l*w

17/2 = l* 17/5

Multiply each side by 5/17

17/2 * 5/17 = l* 17/5 * 5/17

5/2 = l

2 1/2 = l

which expression represents a circle with a center at (2, -8) and a radius of 11?

Answers

Answer:

(x - 2)² + (y + 8)² = 121

Step-by-step explanation:

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) = (2, - 8) and r = 11, hence

(x - 2)² + (y + 8)² = 121


The equation [tex]\((x-2)^2 + (y + 8)^2 = 121\)[/tex] represents a circle with a center at (2, -8) and a radius of 11. This is derived from the general circle equation [tex]\((x - h)^2 + (y - k)^2 = r^2\).[/tex]

The correct equation representing a circle with a center at (2, -8) and a radius of 11 is option (b) [tex]\((x-2)^2 + (y + 8)^2 = 121\)[/tex].

The general equation of a circle is [tex]\((x - h)^2 + (y - k)^2 = r^2\)[/tex], where (h, k) is the center and r is the radius.

In option (b), [tex]\((x-2)^2 + (y + 8)^2 = 121\)[/tex], the values match the given center (2, -8) and radius of 11. The squared terms with (x-2) and (y+8) are in the correct form, and the radius squared [tex](\(11^2 = 121\))[/tex] is on the right side.

Options (a), (c), and (d) do not represent the given circle because they have incorrect signs, centers, or radius values. Therefore, the correct equation is option (b).

justin starts a bank account with $85 in his savings,and he puts in an additional 15 dollars a month towards his savings

Answers

Answer:

y = 15x + 85

Step-by-step explanation:

Let:

x = amount of months ; y = total amount

The constant is 85, meaning that this number will not change (for he would have at least 85 no matter how much time has passed).

15 is next to a variable, for depending on the amount of time passed, you will add a certain amount of "15" to the answer.

y is your total, and is also a variable, because it also depends on the amount of time that passes.

A lit house worker is tracking a boat that is 2.1 km south from her. She is also tracking a boat that is 3.5 km from the tower located 70 degrees east of north. To the nearest tenth of a kilometer, how far apart are the two boats?

Answers

Answer:

21.5 km

Step-by-step explanation:

We have to find the distance  between two boat

We are given that

AC=2.1 km

BC=3.5 km

We have to find BC

The angle between two boat =110 degrees

Using cosine law

BC=[tex]\sqrt{(2.1)^2+(3.5)^2-2\cdot(2.1)\cdot(3.5)cos 110}[/tex]

BC=[tex]\sqrt{4.41+12.25+ 2\cdot2.1\times3.5cos 70[/tex]

BC=[tex]\sqrt{4.41+12.25+9.3051}[/tex]

BC=21.507 km

Hence, the distance between two boat is 21.5 km

Final answer:

The distance between the two boats can be determined using the law of cosines. Inserting the provided values into the formula yields a distance of approximately 3.9 kilometers.

Explanation:

To solve this problem, we can apply the law of cosines, which states that c² = a² + b² - 2ab(cos Θ), where a and b are lengths of two sides of a triangle, c is the length of the third side, and Θ is the angle between sides a and b. Let's consider our light house worker as a starting point. The boat at 2.1 km south constitutes one side of the triangle (a = 2.1 km). The other boat, at 3.5 km 70° east of north, constitutes the second side (b = 3.5 km). The angle Θ between side a and side b is 70°. Therefore, the distance between the two boats (c) can be calculated as follows:

c² = a² + b² - 2ab(cos Θ) = (2.1 km)² + (3.5 km)² - 2 *(2.1 km)*(3.5 km) cos(70°)

Computing the above gives a distance of approximately 3.9 km.

Rohan invested in a precious mineral. The value of the mineral tends to increase by about 9% per year. He invests $12,000 in 2018.

How much more will his investment be worth by 2025?



Enter your answer in the box.

Round to the nearest whole dollar.

Answers

Answer:

$9,936.47

Step-by-step explanation:

Similarly to the other problem I helped you with we have:

[tex]A_{final}=A_{initial}(1+r)^t[/tex]

Where A is amount, r is rate and t is time.

In this case A=12000, r=9%=0.09 and 9% in decimals is 0.09 (9÷100=0.09), and t=7 since 2025 -2018 = 7 years. So how much is this investment worth in 7 years? Let's plug those values in and we obtain:

[tex]A_{final}=12000(1+0.09)^7=12000(1.09)^7=21936.47[/tex]

So the investment will be worth $21,936.47.  Now we must calculate how much more will this precious mineral be worth so we get the difference of the final amount and the initial amount the mineral was worth and so:

[tex]A_{final}-A_{initial}=21936.47-12000=9936.47[/tex]

And so the mineral will be worth $9,936.47 more than it originally was worth after 7 years.

Final answer:

The king size chocolate bar is three times as long as the regular bar, so given that the regular bar is 5 4/9 inches long, the king size bar is 16 1/3 inches long.

Explanation:

The problem involves a regular size chocolate bar that is 5 4/9 inches long and a king size bar that is three times as long. Given the length of the regular bar, our objective is to find out how long the king size bar is.

We start by converting the mixed number 5 4/9 into an improper fraction which gives us 49/9 inches. We then multiply 49/9 by 3 to get the length of the king size bar which is 147/9 inches. Converting this improper fraction back into a mixed number, we get 16 1/3 inches. Therefore, the king size bar is 16 1/3 inches long.

The area of a square is (4x + 3)^2 square inches. The perimeter of the square is 172 inches. What is the value of x?

Answers

Answer:

x = 10

Step-by-step explanation:

the area of a square = s² ( s is the side length )

s² = (4x + 3)² ( take the square root of both sides )

s = [tex]\sqrt{(4x+3)^2}[/tex] = 4x + 3

perimeter = 4s = 172, that is

4(4x + 3) = 172 ( distribute left side )

16x + 12 = 172 ( subtract 12 from both sides )

16x = 160 ( divide both sides by 16 )

x = 10

In a rectangle the length is 2 cm longer than the width. If its length and width are both increase by 4 cm it's area is increased by 56 cm. Find the original length and width.

Answers

Answer:

Length = 6 cm and width = 4 cm.

Step-by-step explanation:

Let the width be x, then the length is x + 2 cm and its area = x(x + 2).

The new width and length are x + 4 and x + 6, and the new area is

(x + 4)(x + 6).

So we have the equation:-

(x + 6)(x + 4) = x(x + 2) + 56

x^2 + 10x + 24 = x^2 + 2x + 56

10x - 2x = 56 - 24

8x = 32

x = 4 cm = width

and length = 4 + 2 = 6 cm
