Answer 1

Answer:

The number of hamburgers is 136.

Step-by-step explanation:

What we know:

We got cheeseburgers and hamburgers

The total: 408

The number of cheese burgers was 2 times the number of hamburgers

This is pretty much all the info we need to know.

Lets define our variables:

x = hamburgers

y = cheeseburgers

Now, we need our two equations to make a system.

[tex]x+y=408[/tex]

[tex]y=2x[/tex]

To find hamburgers, x, we plug the value of y into our first equation.

[tex]x+2x=408[/tex]

Add like terms

[tex]3x=408[/tex]

Divide by 3

[tex]x=136[/tex]

The number of hamburgers is 136.

Just to check our work, lets find the cheeseburgers.

[tex]y=2(136)[/tex]

[tex]y=272[/tex]

[tex]272+136=408[/tex]

By derivative rules we find the following conclusions from functions:

The second derivative of the function y = 3 / x - 7 · ㏑ x is equal to y'' = 6 / x³ + 7 / x².The value of the second derivative of the function s = 2 / t - 2 / t² for t = 2 is equal to - 1 / 4 feet per square second.

How to apply derivative rules and evaluate derivatives

In this question we find two cases where the second derivative of a function must be found, this can be done by applying derivative rules twice. The first case consists in determining the second derivative of the following function:

y = 3 / x - 7 · ㏑ x

First derivative

y' = - 3 / x² - 7 / x

Second derivative

y'' = 6 / x³ + 7 / x²

The second case requires the determination and evaluation of the second derivative of the following function:

s = 2 / t - 2 / t², t = 2

First derivative

s' = - 2 / t² + 4 / t³

Second derivative

s'' = 4 / t³ - 12 / t⁴

Evaluation

s'' = 4 / 2³ - 12 / 2⁴

s'' = 1 / 2 - 3 / 4

Answers

To find zx and zy, we need to take partial derivatives of z with respect to x and y. Taking z with respect to x, we get zx = 3x2 + 12xy and zy = 6x + 16y. Taking z with respect to y, we get zy = 6x + 16y and g(x, y) = 3xy - 7x. Therefore, gx = 3y - 7 and gy = 3x.

What is derivative?

A derivative is a measure of how much a function changes as its input changes. More specifically, the derivative of a function at a particular point is the slope of the function at that point, which describes how quickly the function is changing at that point.

Geometrically, the derivative of a function at a given point can be thought of as the slope of the tangent line to the function at that point.

To find zx and zy, we need to take partial derivatives of z with respect to x and y, respectively.

Given z = [tex]x^3 + 6x^2y + 8y^2[/tex],

Taking partial derivative of z with respect to x, we get:

zx = [tex]3x^2 + 12xy[/tex]

Taking partial derivative of z with respect to y, we get:

zy = 6x + 16y

Therefore, zx = 3x^2 + 12xy and zy = 6x + 16y.

Given g(x, y) = 3xy - 7x,

Taking partial derivative of g with respect to x, we get:

gx = 3y - 7

Taking partial derivative of g with respect to y, we get:

gy = 3x

Therefore, gx = 3y - 7 and gy = 3x.

Slope models the direction and steepness of a line, while the y intercept defines the starting point. Explain what following equation of a line represents y=-2/3x+6

Answers

The equation y = (-2/3)x + 6 represents a line that is decreasing from left to right and intersects the y-axis at the point (0, 6).

What is the Slope?

The slope refers to the measure of the steepness of a line or a curve. It is defined as the ratio of the vertical change (rise) to the horizontal change (run) between any two points on the line or the curve.

The equation of a line can be written as with the help of slope intercept form is given by:

y = mx + b

Where "b" is the y-intercept and "m" is the line's slope of the line.

In the equation y = (-2/3)x + 6, we can see that the slope 'm' is -2/3, which means that for every unit increase in x, the y-value decreases by 2/3 of a unit. This tells us that the line represented by this equation is decreasing (i.e., sloping downwards) from left to right.

The y-intercept 'b' is 6, which means that the line intersects the y-axis at the point (0, 6). This is the starting point of the line, where the value of y is 6 when x is 0.

Therefore, the equation y = (-2/3)x + 6 represents a line that is decreasing from left to right and intersects the y-axis at the point (0, 6).

Answers

The correct next step in the proof is A. Statement: ∠6 ≅ ∠14 Reason: For parallel lines cut by a transversal, corresponding angles are congruent.

Since p || q and r || s, we know that angle 6 and angle 14 are corresponding angles. By the Corresponding Angles Theorem, we know that corresponding angles are congruent when parallel lines are cut by a transversal. Therefore, we can say that ∠6 ≅ ∠14.

To prove that ∠1 and ∠14 are supplementary angles, we can use the fact that ∠1 and ∠6 are a linear pair, which means that they are adjacent angles that form a straight line and are therefore supplementary. Since ∠6 ≅ ∠14, we can substitute ∠14 for ∠6 in the equation to get:

∠1 + ∠14 = 180°

Therefore, we have proved that ∠1 and ∠14 are supplementary angles.

Answers

Answer:

These distances show that AB, which is only 10 nautical miles apart, and AB are the closest pair of islands.

Step-by-step explanation:

We must first locate the three pairs of islands in order to establish which pair is nearest before determining the safest route for the ship.

Give the three islands the letters A, B, and C. The three island groups are designated as AB, AC, and BC. Finding the closest pair is necessary.

We can leverage the separation between the islands to do this. Assuming that the islands are separated by the following distances:

A and B are separated by 10 nautical miles.

A and C are separated by 15 nautical miles.

B and C are separated by 12 nautical miles.

These distances show that AB, which is only 10 nautical miles apart, and AB are the closest pair of islands.

Share #720 among A, B and C in the ratio 2:3​

Answers

When $720 is shared among A, B, and C in the ratio of 1:2:3, each individual will get:

A = $120B = $240C = $360.

What is the sharing ratio?

The sharing ratio describes the ratio, proportion, or relative size of profit or an amount that a sharing partner receives.

Ratios are expressed in percentages, decimals, fractions, or in standard ratio form (:).

Sharing ratios are based on some agreed factors or criteria.

The total sum to be shared = $720

The sharing ratio = 1:2:3

The sum of ratios = 6

A's share of $720 = $120 ($720 x 1/6)

B's share of $720 = $240 ($720 x 2/6)

C's share of $720 = $360 ($720 x 3/6)

Thus, based on their sharing ratios, A will receive $120, B $240,and C $360 from the total of $720.

The sum of the sides of a regular polygon is 96ft, find the measure of it side.​

Answers

Answer:

two are supplementary. the measure of one of these angles is 12 degrees less than one-third the measure of the other.what is the measure of each angle

Let's call the measures of the two angles x and y, where x is the larger angle. We know that the two angles are supplementary, which means they add up to 180 degrees:

x + y = 180

We also know that one of the angles (let's say y) is 12 degrees less than one-third the measure of the other angle (x):

y = (1/3)x - 12

Now we can substitute the second equation into the first equation to solve for x:

x + (1/3)x - 12 = 180

Multiplying both sides by 3 to get rid of the fraction, we have:

3x + x - 36 = 540

Combining like terms, we get:

4x - 36 = 540

Adding 36 to both sides, we get:

4x = 576

Dividing both sides by 4, we get:

x = 144

Now we can use the first equation to solve for y:

144 + y = 180

Subtracting 144 from both sides, we get:

y = 36

Therefore, the measures of the two angles are 144 degrees and 36 degrees.

The sum of the sides of a regular polygon is 96ft, find the measure of it side.

Let's say that the regular polygon has n sides, and each side has length s. The formula for the sum of the sides of a regular polygon is:

sum of sides = n * s

We know that the sum of the sides is 96ft, so we can write:

96 = n * s

We want to find the length of each side, so we need to isolate s on one side of the equation. We can do this by dividing both sides by n:

s = 96/n

Now we can substitute this expression for s into the formula for the perimeter of a regular polygon:

Perimeter = n * s

Perimeter = n * (96/n)

Simplifying this expression, we get:

Perimeter = 96

We know that the perimeter of a regular polygon is the sum of the lengths of all its sides, so we can divide the perimeter by the number of sides to find the length of each side:

s = Perimeter / n = 96 / n

Therefore, the length of each side of the regular polygon is 96/n feet. We cannot determine the value of n from the given information in the problem.

The length of a rectangle is 7 inches more than its width. The area of the rectangle is equal to 2 inches more than 2 times the perimeter. Find the length and width of the rectangle.

Answers

The length and width οf the rectangle are 11 inches and 4 inches, respectively.

What is area οf rectangle ?

Area οf rectangle can be defined as prοduct οf length , breadth οf a rectangle.

Let's denοte the width οf the rectangle as w. Then accοrding tο the prοblem, the length οf the rectangle is 7 inches mοre than the width, sο we can express the length as w + 7.

The area οf the rectangle is given by:

[tex]A = length * width = (w + 7) * w = w^2 + 7w[/tex]

The perimeter οf the rectangle is given by:

[tex]P = 2 * (length + width) = 2 * (w + 7 + w) = 4w + 14[/tex]

According tο the problem, the area of the rectangle is equal to 2 inches mοre than 2 times the perimeter, so we can set up the following equation:

[tex]w^2 + 7w = 2(4w + 14) + 2[/tex]

Simplifying this equatiοn, we get:

[tex]w^2 + 7w = 8w + 28[/tex]

Subtracting 8w + 28 frοm both sides, we get:

[tex]w^2 - w - 28 = 0[/tex]

We can factοr this quadratic equation as:

[tex](w - 4)(w + 7) = 0[/tex]

Therefοre, we have twο sοlutiοns fοr w: w = 4 and w = -7. Hοwever, since the width οf the rectangle cannοt be negative, we reject the sοlutiοn w = -7 and chοοse w = 4 as the width οf the rectangle.

Then, the length οf the rectangle is w + 7 = 4 + 7 = 11 inches.

Therefοre, the length and width οf the rectangle are 11 inches and 4 inches, respectively.

The Half-life of radium is 1690 years. If 70 grams are present now, how much is left in 710 years

Answers

Answer: 46.39 grams of radium

Step-by-step explanation:

We can use the half-life formula to solve this problem:

A = A₀(1/2)^(t/t₁/₂)

where:

A₀ = initial amount (present)

A = final amount (in 710 years)

t = time elapsed (710 years)

t₁/₂ = half-life (1690 years)

First, we need to calculate the number of half-lives that will occur in 710 years:

n = t / t₁/₂

n = 710 / 1690

n ≈ 0.42

This means that in 710 years, the amount of radium will be reduced to half its current amount (1/2). And then reduced to half again (1/2 * 1/2) in another 1690 years.

Now we can calculate the final amount of radium after 710 years:

A = A₀(1/2)^n

A = 70(1/2)^0.42

A ≈ 46.39 grams

Therefore, after 710 years, approximately 46.39 grams of radium will be left.

the sum of the base and the height of a triangle is 22cm find the dimension for which the area is a maximum height and base

Answers

Answer: Let's call the base of the triangle "b" and the height of the triangle "h". We are given that the sum of the base and the height is 22 cm, so we can write:

b + h = 22

We want to find the dimensions for which the area of the triangle is a maximum. The formula for the area of a triangle is:

A = (1/2)bh

We can use the equation b + h = 22 to solve for h in terms of b:

h = 22 - b

We can substitute this expression for h into the formula for the area:

A = (1/2)b(22 - b)

Simplifying this expression, we get:

A = 11b - (1/2)b^2

To find the value of "b" that maximizes the area, we can take the derivative of this expression with respect to "b" and set it equal to zero:

dA/db = 11 - b = 0

Solving for "b", we get:

b = 11

Substituting this value of "b" back into the equation b + h = 22, we get:

h = 22 - b = 22 - 11 = 11

Therefore, the dimensions for which the area of the triangle is a maximum are:

base = 11 cm

height = 11 cm

And the maximum area is:

A = (1/2)bh = (1/2)(11 cm)(11 cm) = 60.5 square cm

The trigonometry equations when evaluated are ∅ = 82π/125 and ∅ = 28π/23

How to evaluate the trigonometry equation

Equation 1

Given that

cos ∅ = -8/17, π/2 < ∅ < π

Take the arc cos of both sides of the equation

So, we have the following

∅ = 82π/125

Equation 2

The trigonometry equation from the question is given as

tan ∅ = 2/5

The domain of the function is given as

π < ∅ < 3π/2

This means that the definition of the function is

tan ∅ = 2/5, π < ∅ < 3π/2

Take the arc tan of both sides of the equation

So, we have the following

∅ = tan⁻¹(2/5), π < ∅ < 3π/2

Express fraction as decimal

This gives

∅ = tan⁻¹(0.4), π < ∅ < 3π/2

Evaluate the arc tan

∅ = 28π/25

Hence, the measure of the angle is approximately 28π/23
