4 divided by 1 1/8 i need this quickkkkkkk

If you can buy 1 bunch of seedless green grapes for $2, then $18 we can buy 9 bunches.

The concept used here is a simple division to find out how many bunches of seedless green grapes can be purchased with a given amount of money.

In this case, we know the cost of one bunch of seedless green-grapes ($2) and we are given a total amount of money ($18) that we can spend on grapes. We can use division to find out how many bunches we can buy with that amount.

⇒ Number of bunches = ($18)/($2) per bunch,

⇒ Number of bunches = 9 bunches;

Therefore, with $18, you can buy 9 bunches of seedless green grapes.

The first step is to draw the coordinates in the cartesian plane:

Next you have to "Mirror" the points, this means, you check the distance over the X-axis and Y-axis for each point and then move to the next cuadrant and using those lengths you find the mirrored point:

So the mirroed ppoints are:

For A (-3,-6) is A' (3,-6)

For B (-5,-1) is B' (5,-1)

For C (-10,-9) is C' ()

Answer: a

Step-by-step explanation:

The difference between their yearly incomes is $31,304.

To calculate each person's yearly income, we need to multiply their weekly income by the number of weeks in a year. Assuming there are 52 weeks in a year, the yearly income can be calculated as follows:

For the student who drops out of high school:

Yearly Income = Weekly Income x Number of Weeks

= 451 x 52

= 23,452

For someone with a bachelor's degree:

Yearly Income = Weekly Income x Number of Weeks

= 1053 x 52

= 54,756

The difference between their yearly incomes can be found by subtracting the student's yearly income from the bachelor's degree holder's yearly income:

Difference = Bachelor's Yearly Income - Student's Yearly Income

= 54,756 - 23,452

= 31,304

Therefore, the difference between their yearly incomes is $31,304.

It is important to note that these calculations are based on the given information and assumptions. The actual yearly incomes may vary depending on factors such as work hours, additional income sources, deductions, and other financial considerations.

Additionally, it is worth considering that educational attainment is just one factor that can influence income, and there are other variables such as experience, job type, and market conditions that may also impact individuals' earnings.

Step-by-step explanation:

The system of equations that has a solution with x-coordinate of 3.5 and 6 is C. y = 1/2x + 3 and y = -(x - 5)² + 7.

To determine if a coordinate is a solution to a system of equations, substitute the values for the x and y in both equations and check if both resulting equations are true. If both resulting equations are true, then the coordinate is a solution to the system of equations.

A. y = x + 3.5

y = 3.5 + 3.5 = 7

y = x² + 6

7 = 3.5² + 6

7 ≠ 18.25

B. y = x - 7

y = 3.5 - 7 = -3.5

y = -(x - 6)²

-3.5 = -(3.5 - 6)²

-3.5 ≠ -6.25

C. y = 1/2x + 3

y = 1/2(3.5) + 3 = 4.75

y = -(x - 5)² + 7

4.75 = -(3.5 - 5)² + 7

4.75 = 4.75

y = 1/2x + 3

y = 1/2(6) + 3 = 6

y = -(x - 5)² + 7

6 = -(6 - 5)² + 7

6 = 6

D. y = 1/2x + 7

y = 1/2(3.5) + 7 = 8.75

y = -(x - 6)² + 3.5

8.75 = -(3.5 - 6)² + 3.5

8.75 ≠ -2.75

Only the system of equation in option C holds the equations true, hence, C. y = 1/2x + 3 and y = -(x - 5)² + 7 are the system of equations that has the given solution stated in the problem.

Answer:

41° and 49°

Step-by-step explanation:

Complementary angles are angles that sum up to 90°.

Let x represent the smaller angle, then the bigger angle will be represented with x + 8:

x + x + 8 = 90°

2x + 8 = 90°

2x = 82°

x = 41° this is the measure of smaller angle, then the bigger angle wpis 49°

The answer is:

Work/explanation:

If two angles are complementary, their measures add to 90°.

So we can set up an equation to find the angles. Let the unknown angle be w, and its complement will be w + 8:

w + w + 8 = 90

Combine like Terms

2w + 8 = 90

2w = 82

w= 41

The other angle measures 8° more than the measure of w:

41 + 8 = 49

What is  Bernoulli differential equation?

A Bernoulli differential equation is a type of non-linear ordinary differential equation of the form:

dy/dx + P(x)y = Q(x)yⁿ

where P(x) and Q(x) are functions of x and n is a constant. The equation is named after the Swiss mathematician Jakob Bernoulli.

These types of differential equations are important in various fields of science, such as physics, engineering, and economics. They are non-linear, meaning that the dependent variable y appears in both linear and non-linear terms, making them difficult to solve in general.

a) This differential equation can be written in the form (*) with P(x) = x, Q(x) = 2x, and n = 2.

b) The substitution u = y⁻¹ will transform it into the linear equation du/dx - xu = -2x.

c) Using the substitution in part (b), we rewrite the initial condition as u(1) = 1/4.

d) Now we solve the linear equation in part (b). The characteristic equation is given by d/dx(e\(\mathrm{(\int -xdx))}\) = -xe\(\mathrm{(\int -xdx))}\) which has the general solution u(x) = Ce\((-x^2/2)\).

Using the initial condition, we find C = 1/4, so u(x) = 1/4e\((-x^2/2)\).

e) Finally, we solve for y. From u = y⁻¹, we have y = 1/u = 4e\((-x^2/2)\).

Answer:

(4k+5)+ (6k+10) = 115

Exterior angle of a triangle is equal to the sum of two opposite interior angles

10k=15=115

10k= 100

k = 100/10

k = 10

Step-by-step explanation:

Answer:

k = 10

Step-by-step explanation:

The 3rd angle that's not defined in the equation is supplementary to 115, so the angle is 180-115 = 65.

We can solve for the equation 65+(4k+5)+(6k+10)=180 -> 65+4k+5+6k+10=180 -> 10k+80 = 180 -> 10k = 100 -> k = 10.

To double-check(optional), we can plug k back into the equation, so 65 + 4*10 + 5 + 6*10 + 10 = 180 -> 100 + 65 + 5 + 10 = 180 -> 180 = 180, so we can confirm that k = 10.

The function has the characteristics is (b) y= (2x^2 - 8) / (x^2 - 9)

The features are given as:

The function that has the above features is (b).

This is proved as follows:

y= (2x^2 - 8) / (x^2 - 9)

Set the denominator not equal to 0, to determine the domain

x^2 - 9 ≠ 0

Add 9 to both sides

x^2 ≠ 9

Take the square roots

x ≠ ±3 --- domain

Replace ≠ with =

x = ±3 --- vertical asymptote

Set the numerator to 0

2x^2 - 8 = 0

Divide through by 2

x^2 - 4 = 0

This gives

x^2 = 4

Take the square roots

x = 2 ---- horizontal asymptote

Hence, the function has the characteristics is (b) y= (2x^2 - 8) / (x^2 - 9)

The linear rule for the sequence is f(n) = 7/20 + 3/20(n - 1)

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

35/100,5/10,65/100

In the above sequence, we can see that 15/100 is added to the previous term to get the new term

This means that

First term, a = 35/100

Common difference, d = 15/100

The nth term is then represented as

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

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

f(n) = 35/100 + 15/100(n - 1)

So, we have

f(n) = 7/20 + 3/20(n - 1)

Hence, the explicit rule is f(n) = 7/20 + 3/20(n - 1)

Part A: β₂ = β₁ + 10 log₁₀ (f)

Part B: Δβ = 20 log10 (d₁/d₂)

This can be solved using the concept of sound intensity.

While amplitude is the distance between a wave's resting position and its crest, sound intensity is defined as the sound power per unit area. The power carried by sound waves per unit area in a direction perpendicular to that region is known as sound intensity or acoustic intensity. The watt per square metre is the SI measure of intensity that includes sound intensity.

Part A:

β₂ - β₁ = 10 log₁₀ (I₂/I₁)

given that : I₂ = f × I₁

hence, I₂/I₁ = f

so the equation becomes:

β₂ - β₁ = 10 log₁₀ (f)

β₂ = β₁ + 10 log₁₀ (f)

Part B:

P = Power by the source

I₁= intensity at distance d1 = P/(4πd₁²)

I₂ = intensity at distance d2 = P/(4πd₂²)

Δβ = β₂ - β₁ = 10 log₁₀ (I₂/I₁)

β₂ - β₁ = 10 log₁₀ ((P/(4πd₂²))/(P/(4πd₁²)))

Δβ = 10log₁₀  ((d₁/d₂)²)

Δβ = 20log₁₀ (d₁/d₂)

Answer

Option A is correct.

Angle L = 55°

Explanation

To answer this, we need to note that the sum of angles in a triangle is 180°

So, we can solve for x by summing up the angles of this triangle and equating them to 180°

Angle J + Angle K + Angle L = 180°

2x + 45° + (x + 15)° = 180°

2x + 45° + x + 15° = 180°

2x + x + 45° + 15° = 180°

3x + 60° = 180°

3x = 180° - 60°

3x = 120°

Divide both sides by 3

(3x/3) = (120°/3)

x = 40°

Angle L = x + 15° = 40° + 15° = 55°
