The price of Apples are $1.13 per pound and peaches are $0.63 per pound Option B

If pears cost $3 for a 4 pound bag, then the price per pound of pears is:

3/4 = $0.75 per pound

Since pears cost less per pound than apples but more per pound than peaches, we can set up the following inequality:

peaches < pears < apples

Substituting the known price per pound of pears, we get:

peaches < $0.75 < apples

Now, we can check each option to see which satisfies the inequality:

Apples are $1.13 per pound and peaches are $1.04 per pound:

$1.04 < $0.75 < $1.13

The comparisons of the fractions given above is enumerated below.

1) To compare 1/8 and 1/9, I can find a common denominator by multiplying the denominators together. The common denominator is 8 x 9 = 72.

Then, I can convert each fraction to have a denominator of 72 by multiplying the numerator and denominator of each fraction by the appropriate factor. The result is 9/72 and 8/72. Since 9/72 is bigger than 8/72, I know that 1/8 is smaller than 1/9.

2) To compare 7/8 and 8/9, I can find a common numerator by multiplying the numerators together. The common numerator is 56. Then, I can convert each fraction to have a numerator of 56 by multiplying the numerator and denominator of each fraction by the appropriate factor. The result is 49/56 and 64/72. Since 64/72 is bigger than 49/56, I know that 8/9 is bigger than 7/8.

3) To compare 15/38 and 5/13, I can find a common numerator by multiplying the numerators together.

The common numerator is 195. Then, I can convert each fraction to have a numerator of 195 by multiplying the numerator and denominator of each fraction by the appropriate factor.

The result is 75/195 and 75/195. Since the numerators are the same, I can compare the denominators. Since 195 is bigger than 169, I know that 15/38 is smaller than 5/13.

Answer:

5 miles / Maria's time = 4 miles / Gus's time

Since both Maria and Gus run for equal periods of time, we can set their times equal to each other:

5 miles / t = 4 miles / t

where t is the time it takes both of them to run.

Simplifying this equation, we can see that the distance Maria runs (M) is equal to the distance Gus runs (G) multiplied by 5/4:

M = (5/4)G

Therefore, the correct equation that relates the variables defined is:

M = (5/4)G

This means that Maria's distance is 1.25 times Gus's distance. So, the correct answer is option B: M = 1.25G.

c. There are approximately 16 hours of daylight on the longest day of the year.

d. There are approximately 8 hours of daylight on the shortest day of the year.

e. The graph for the function is obtained.

What is a function?

In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.

The function is given as y = 4 sin [(2π / 365)(x - 79)] + 12.

a. The amplitude of the function is the coefficient of the sine function, which is 4.

Therefore, the amplitude of the function is 4.

b. The period of the function is given by the formula: period = (2π/b), where b is the coefficient of x in the sine function.

In this case, b = (2π/365), so the period is -

period = (2π / (2π/365)) = 365

Therefore, the period value is 365 days.

c. The longest day of the year occurs on the summer solstice, which is around June 21.

On this day, x = 171 (assuming January 1 is x = 1). Plugging x = 171 into the function gives -

y = 4 sin [(2π/365)(171 - 79)] + 12 = 15.998 hours

Therefore, the number of hours for daylight is 16 hours.

d. The shortest day of the year occurs on the winter solstice, which is around December 21.

On this day, x = 355. Plugging x = 355 into the function gives -

y = 4 sin [(2π/365)(355 - 79)] + 12 = 8.002 hours

Therefore, the number of hours for daylight is 8 hours.

e. To graph the function for one period, we need to find the values of y for x ranging from 1 to 365.

We can use a graphing tool or software to plot the function.

The graph is plotted.

The x-axis represents the number of days after January 1, and the y-axis represents the number of hours of daylight.

The function oscillates between 8 and 16 hours of daylight over the course of one year, with the maximum occurring around day 171 and the minimum occurring around day 355.

The graph shows that the function is periodic, with a period of 365 days, as expected.

The volume of the top part of the pyramid is 13.4% of the total volume.

The amount of mass that a material has in relation to its volume is measured by its density. By dividing the substance's mass by volume, it is determined. Density is calculated as follows: density = mass/volume

A fundamental idea in physics, density is utilised in many branches of research and engineering, including the construction of effective engines and turbines, calculating the buoyancy of objects in fluids, and forecasting the behaviour of materials under stress.

Given that, average density of the entire pyramid is 4.7g/cm3 and that the bottom part has a mass of 972.8g.

The density is given as:

density = mass/volume

Substituting the value we have:

4.7g/cm3 = 972.8g/volume

volume = 207.23 cubic cm.

For the top part, density of 2.9g/cm3 and a mass of 92.8g. :

density = mass/volume

2.9g/cm3 = 92.8g/volume

volume = 32 cubic cm.

The percent of the top part with respect to total volume is:

percentage = (volume of top part / total volume) x 100

total volume = volume of top part + volume of bottom part

total volume = 32 cm3 + 207.23 cm3

total volume = 239.23 cm3

percentage = (32 cm3 / 239.23 cm3) x 100

Answer:

To solve this problem, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

where:

A = the final amount

P = the principal (initial amount)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the time (in years)

In this case, we have:

P = $200.00

r = 0.09 (9% expressed as a decimal)

n = 1 (compounded annually)

t = 5 years

Plugging these values into the formula, we get:

A = $200.00(1 + 0.09/1)^(1*5)

A = $200.00(1.09)^5

A = $200.00(1.538624)

A parabola is a U-shaped curve in mathematics that is produced by the graph of a quadratic function. It is a particular kind of conic section, which is a circle made when a plane and a cone cross each other. A quadratic function with the following standard form can depict a parabola: Y = ax2+bx+c where are constants a, b, and c. Which way the parabola expands depends on the sign of the coefficient a.

given

We can use the following formula to express the equation of a parabola given a focus and a directrix:

where (h,k) is the parabola's vertex, p is the separation between it and the centre, and the directrix is represented by the horizontal line y = k - p.

The centre in this instance is (1,11), and the directrix is y=3.

We also understand that p is the distance, in this instance 4 units, between the vertex and the focus (since the focus is 4 units above the vertex). Therefore, we can enter the numbers into the formula to obtain:

The angle measure of minor arc QS is 92 degrees, and the angle measure of angle QQS is 46 degrees.

What is Angle?

In geometry, an angle is a figure formed by two rays that have a common endpoint, called the vertex of the angle. The rays that form the angle are called the sides of the angle. Angles are typically measured in degrees or radians and are used to describe the amount of rotation between two intersecting lines or planes.

In a circle, the measure of an inscribed angle is equal to half the measure of the intercepted arc. Since QS intercepts the minor arc QR, the measure of angle QRS is equal to half the measure of the minor arc QS.

Therefore, if m∠QRS = 46, then m(arc QS) = 2×m∠QRS = 2×46 = 92 degrees.

Since the measure of an arc is equal to the measure of the central angle that intercepts it, and the sum of the measures of the central angles in a circle is 360 degrees, we have:

m(arc QS) + m(arc QR) = 360 degrees

Substituting the value of m(arc QS) that we found above, we get:

92 degrees + m(arc QR) = 360 degrees

Solving for m(arc QR), we get:

m(arc QR) = 360 degrees - 92 degrees = 268 degrees

Since QS is a minor arc of the circle, the measure of angle QQS is equal to half the measure of the arc QS. Therefore, we have:

m∠QQS = 0.5×m(arc QS) = 0.5×92 = 46 degrees

Therefore, the angle measure of minor arc QS is 92 degrees, and the angle measure of angle QQS is 46 degrees.

Step-by-step explanation:

N′(−11, −2), M′(−8, −1), O′ (−11, −5)

The image coordinates of N′M′O′ if the preimage is translated 7 units to the left are N′(−11, −2), M′(−8, −1), O′ (−11, −5). This is calculated by subtracting 7 from the x-coordinate of each point in the original triangle NMO. For example, the x-coordinate of point N in the original triangle is -4, so the x-coordinate of point N′ in the translated triangle is -4 - 7 = -11. The y-coordinate of point N does not change, so the y-coordinate of point N′ is also -2.

Answer:

To translate the triangle 7 units to the left, we need to subtract 7 from the x-coordinates of each vertex:

N' = (N_x - 7, N_y) = (-4 - 7, -2) = (-11, -2)

M' = (M_x - 7, M_y) = (-1 - 7, -1) = (-8, -1)

O' = (O_x - 7, O_y) = (-4 - 7, -5) = (-11, -5)

Therefore, the image coordinates of N'M'O' are (-11, -2), (-8, -1), and (-11, -5).

So the answer is N′(−11, −2), M′(−8, −1), O′ (−11, −5).

We have the requirements to find the area, with the value of the radius.

Solve for the area;

[tex]Area = \pi(12)^2[/tex]

[tex]Area = 144 \pi[/tex] (Exact)

[tex]Area = about \ 452.39.[/tex] (Approx.)

Answer:

One solution at (2, -1)

Step-by-step explanation:

You will want to write the equations for both pairs of points:

(-2,-3) and (0,-2)

The slope is the change in y over the change in x.  The first number of the ordered pairs is the x value and the second number in the ordered pair is the y values.  Find the change by subtraction

[tex]\frac{-2 - -3}{0 - -2}[/tex] = [tex]\frac{-2+ 3}{0 + 2}[/tex] = [tex]\frac{1}{2}[/tex]

The slope (m) is 1/2.

The y intercept is when x = 0.  In the point (0,-2) x is 0, so the y-intercept is -2.

The y-intercept (b) is -2.

y = mx + b  Substitute 1/2 for m and -2 for b

y = [tex]\frac{1}{2}[/tex]x - 2

(0,3) and (1,1)

The slope is

[tex]\frac{1-3}{1-0}[/tex] = [tex]\frac{-2}{1}[/tex] = -2

The slope is --2.

The y intercept is 3.

y = mx + b  Substitutes -2 for m and 3 for b.

y = -2x + 3

Set the 2 equation equal to each other and solve for x.

-2x + 3 = 1/2 x -2   Multiply all the way through by 2 to clear the fraction.

-4x + 6 = x - 4   Add 4x to both sides

-4x + 4x + 6 = x + 4x -4

6 = 5x -4  Add 4 to both sides

6 + 4 = 5x - 4 + 4

10 = 5x  Divide both sides by 5

2 = x

Take either of the two original equations and substitute 2 for x and solve for y

y = -2x + 3

y = -2(2) + 3

y = -4 + 3

y = -1

The solution is (2,-1)
