The amount of snowfall in December was 5 7/8 feet. The amount of snowball in October was 1/4 feet. How much more snowfall was there in December? Write your answer as a mixed number in simplest form.

Answers

Answer 1

Answer: 5 5/8 more feet of snow in December.

Step-by-step explanation: 5 7/8 also equals 47/8, and we need convert 1/4 to something over 8 so we can subtract the two. 1/4, but multiply both sides by 2 is 2/8. 47/8-2/8=45/8. 45/8 as a mixed fraction is 5 5/8.

During halftime of a basketball ​game, a sling shot launches​ T-shirts at the crowd. A​ T-shirt is launched with an initial upward velocity of 78 feet per second. The hight of the t-shirt (h) in feet after t seconds is given by the function h=-16t^2+78t+5. How long will it take the​ T-shirt to reach its maximum​ height? What is its maximum height?

Answers

A​ T-shirt is launched with an initial upward velocity of 78 feet per second, the T-shirt will reach its maximum height in approximately 2.44 seconds.

The height of the T-shirt is given by the function h(t) = -16t^2 + 78t + 5, where h is the height in feet and t is the time in seconds.

To find the time it takes for the T-shirt to reach its maximum height, we need to find the vertex of the parabolic function.

The vertex occurs at the time t = -b/2a, where a = -16 and b = 78 are the coefficients of the quadratic function.

t = -b/2a = -78/(2*(-16)) = 2.4375

Therefore, the T-shirt will reach its maximum height in approximately 2.44 seconds.

To find the maximum height, we substitute this value of t into the equation for h:

h(2.4375) = -16(2.4375)^2 + 78(2.4375) + 5 ≈ 97.19 feet

Therefore, the maximum height of the T-shirt is approximately 97.19 feet.

y = |x - 5| + |x + 5| if -5 < x < 5

Answers

Step-by-step explanation:

This function has two pieces, each of which is the absolute value of a linear expression. We need to consider the function separately for different ranges of x.

When -5 < x < 0, then x + 5 is negative and x - 5 is also negative. Therefore, we have:

y = -(x - 5) - (x + 5) = -2x

When 0 ≤ x < 5, then x + 5 is positive and x - 5 is negative. Therefore, we have:

y = (x - 5) + (x + 5) = 2x

So the function y = |x - 5| + |x + 5| can be written as:

y =

-2x if -5 < x < 0

2x if 0 ≤ x < 5

Notice that the function is not defined for x ≤ -5 or x ≥ 5.

Football is 360ft.long 160ft.wide use 8lb. Fertilizer per 1000sqft it come in 50lb bag. How many bags will I need

Answers

We number of bags is 10 bags of fertilizer to complete the job.

Describe Algebra?

Algebra is a branch of mathematics that deals with the study of mathematical symbols and their manipulation. It involves the use of letters, symbols, and equations to represent and solve mathematical problems.

In algebra, we use letters and symbols to represent unknown quantities and then use mathematical operations such as addition, subtraction, multiplication, division, and exponentiation to manipulate those quantities and solve equations. We can use algebra to model and solve real-world problems in various fields such as science, engineering, economics, and finance.

The total area of the football field is:

360 feet × 160 feet = 57,600 square feet

To find out how many bags of fertilizer are needed, we need to calculate how many 1000-square-foot areas there are on the field:

57,600 square feet ÷ 1000 square feet/area = 57.6 areas

So there are 57.6 areas on the football field.

We need 8 pounds of fertilizer per 1000 square feet, so to find out how many pounds we need for the whole field, we can multiply by the number of areas:

8 pounds/1000 square feet × 57.6 areas = 460.8 pounds

Therefore, we need 460.8 pounds of fertilizer to cover the football field.

Since the fertilizer comes in 50-pound bags, we can divide the total amount of fertilizer needed by 50 to find out how many bags we need:

460.8 pounds ÷ 50 pounds/bag ≈ 9.22 bags

We can't buy a fraction of a bag, so we need to round up to the nearest whole bag. Therefore, we need 10 bags of fertilizer to complete the job.

If a sound with frequency fs is produced by a source traveling along a line with speed vs. If an observer is traveling with speed vo along the same line from the opposite direction toward the source, then the frequency of the sound heard by the observer is
fo =

c + vo
c − vs

fs
where c is the speed of sound, about 332 m/s. (This is the Doppler effect.) Suppose that, at a particular moment, you are in a train traveling at 32 m/s and accelerating at 1.1 m/s2. A train is approaching you from the opposite direction on the other track at 40 m/s, accelerating at 1.5 m/s2, and sounds its whistle, which has a frequency of 460 Hz. At that instant, what is the perceived frequency that you hear? (Round your answer to one decimal place.)

Answers

Doppler Effect happens when there is shift in frequency during a realtive motion between a source and the observer of that source.

It can be calculated as:

[tex]f_o=f_s\huge \text(\dfrac{c+v_o}{c+v_s}\huge \text )[/tex]

where:

c is the speed of light (c = 332m/s)

all the subscripted s is related to the Source (frequency, velocity);

all the subscripted o is related to the Observer (frequency, velocity);

As the source is moving towards the observer and the observer is moving towards the source, the velocities of each are opposite related to direction.

So, the frequency perceived by the observer:

[tex]f_o=460\huge \text(\dfrac{332+32}{332-40}\huge \text)[/tex]

[tex]f_o=460\huge \text(\dfrac{364}{292}\huge \text)[/tex]

[tex]f_o=460(1.247)[/tex]

[tex]f_o= 573.6 \ \text{Hz}[/tex]

At this condition, the observer hears the train's horn in a perceived frequency of 573.6 Hz

Answer:

The perceived frequency of sound is the amount of sound wave that pass a point in a given amount of time

The perceived frequency you hear is

370.9 Hertz

The function is given as:

[tex]f_{o}=\frac{c+V_{o} }{c-V_{o} }[/tex] x  [tex]f_{s}[/tex]

From the question

[tex]c=332[/tex] --- speed of the sound

[tex]V_{o} =32[/tex] ---current speed of the train

[tex]V_{s} = 40[/tex] --- speed of the opposite train

[tex]f_{s} =460[/tex] --- frequency of the sound wave

This gives:

[tex]f_{o}= \frac{332-32}{332+40}[/tex]  ×[tex]460[/tex]

[tex]f_{o}= \frac{300}{372} x460[/tex]

C. One has 90% confidence that the sample proportion is equal to the population proportion.
D. There is a 90% chance that the true value of the population proportion will fall between the lower bound and the
upper bound.

Answers

a) Since n = 1093, x = 538, and we are using a 90% confidence level, we can find the standard error of the proportion using the following formula:

standard error = sqrt((p-hat * (1 - p-hat)) / n)

where p-hat is the sample proportion.

Substituting the given values:

p-hat = x / n = 538 / 1093 = 0.4925

standard error = sqrt((0.4925 * (1 - 0.4925)) / 1093)

standard error ≈ 0.015

b) To find the margin of error, we can use the formula:

margin of error = z* * standard error

where z* is the z-score corresponding to the desired confidence level.

Since we are using a 90% confidence level, the z-score is 1.645 (see the table of z-scores).

Substituting the values:

margin of error = 1.645 * 0.015

margin of error ≈ 0.025

Therefore, the margin of error is approximately 0.025.

c) The confidence interval can be constructed using the formula:

confidence interval = p-hat ± margin of error

Substituting the given values:

confidence interval = 0.4925 ± 0.025

confidence interval = (0.4675, 0.5175)

Therefore, the 90% confidence interval for the proportion of people who feel vulnerable to identity theft is (0.4675, 0.5175).

d) The correct statement that interprets the confidence interval is:

OA. One has 90% confidence that the interval from the lower bound to the upper bound actually does contain the true value of the population proportion.

This statement means that if we repeated the sampling process many times and constructed a 90% confidence interval each time, approximately 90% of the intervals would contain the true proportion of people who feel vulnerable to identity theft.

Answer:

constant of proportionality: A 4equation: D m = 4c

Step-by-step explanation:

Given a graph of muffins versus cups of flour, you want to know the constant of proportionality and the equation relating muffins (m) and cups (c).

Slope

The slope of the line on the graph is easily found by looking at the "muffins" (y) value for "cups" (x) equal to 1. That point is (c, m) = (1, 4).

The line goes through the origin (0, 0), so the slope is the ratio of y to x.

  m = y/x = 4/1 = 4

This is the constant of proportionality.

The constant of proportionality is 4, choice A.

The equation of a proportional relationship is ...

  y = kx . . . . . . where k is the constant of proportionality

Here, the independent variable (horizontal axis) is "cups", represented by 'c'. The dependent variable is "muffins", represented by 'm'. Using the above constant of proportionality, the equation is ...

Answers

Okay, here are the steps to solve this:

* The recipe calls for 1 teaspoon of cinnamon for every 4 cups of granola mix.

* We are making 12 cups of granola.

* So to make 12 cups, we need 12 / 4 = 3 times as much cinnamon.

* Since each 4 cups uses 1 teaspoon, 12 cups will need 3 teaspoons.

Therefore, for 12 cups of granola mix, the recipe will call for 3 teaspoons of cinnamon.

Two forces of 637 newtons and 238 newtons act a point.The resultant force is 714 newtons. find the angle between the forces

Answers

We can use the cosine law to find the angle between the two forces. Let's denote the angle between the 637 N force and the resultant force as θ. Then we have:

714^2 = 637^2 + 238^2 - 2 * 637 * 238 * cos(θ)

Rearranging and solving for cos(θ), we get:

cos(θ) = (637^2 + 238^2 - 714^2) / (2 * 637 * 238)

cos(θ) = -0.0130

Taking the inverse cosine, we get:

θ = 180° - acos(-0.0130)

θ = 175.8° (rounded to one decimal place)

Therefore, the angle between the two forces is approximately 175.8 degrees.

23. By the diagram, the triangle is a [tex]45^\circ - 45^\circ-90^\circ[/tex] triangle. Therefore, the triangle is isosceles, so [tex]x=6.[/tex] And by the Pythagorean theorem, [tex]y^2=x^2+6^2=6^2+6^2=72,[/tex] and taking the square root yields [tex]y = 6\sqrt{2}.[/tex]

24. Notice that by the diagram, the triangle is a [tex]30^\circ-60^\circ-90^\circ[/tex] triangle. It is well known that in these special types of triangles, if [tex]a[/tex] is the side length opposite the [tex]30^\circ[/tex] angle, then the side length opposite the [tex]90^\circ[/tex] angle is [tex]2a,[/tex]  and finally the side length opposite the [tex]60^\circ[/tex]  is [tex]a\sqrt{3}.[/tex] This is shown in the image I've attached below, and can also be easily proven by the fact that two of these triangles combine to form an equilateral triangle.

So using this fact, we know that [tex]x = \frac{8}{2} = 4,[/tex] and [tex]y = x\sqrt{3} = 4\sqrt{3}.[/tex]

25. Tell whether the given side lengths can represent the sides of a right triangle: 10, 12, 20

For this question, we simply use the converse of the Pythagorean theorem. One part of its statement says that if a triangle has sides of length [tex]a, b, c[/tex] such that [tex]a^2 + b^2 = c^2[/tex], and [tex]c[/tex] is the longest side, then the angle opposite the side of length [tex]c[/tex] is a right angle.

Thus, if the triple [tex](a, b, c)[/tex] does not satisfy the equation, the triangle it forms is not a right triangle. In our case, the corresponding values for [tex](a, b, c)[/tex] are [tex](10, 12, 20),[/tex] because [tex]20[/tex] is the largest number in this triple. But [tex]10^2+12^2=244\neq 400 = 20^2,[/tex] so the triangle with side lengths [tex]10, 12, 20[/tex] is not a right triangle.

26. Another statement of the converse of the Pythagorean theorem is that if a triangle has side lengths [tex]a, b, c[/tex] such that [tex]c^2 > a^2+b^2[/tex] , with [tex]c[/tex] being the longest side, then the triangle is an obtuse triangle. So the corresponding values for [tex]a, b, c[/tex] are [tex]10, 11, 14,[/tex] and because [tex]14^2 = 196 < 221 = 10^2+11^2,[/tex] the triangle is an obtuse triangle.

Use spherical coordinates to evaluate the triple integral ∫∫∫Ex2+y2+z2dV
, where E is the ball: x2+y2+z2≤81
.

Answers

[ rate 5stars~ and give thanks for more po! welcome! ]

Step-by-step explanation:

We have the triple integral:

∫∫∫E x^2 + y^2 + z^2 dV

where E is the ball x^2 + y^2 + z^2 ≤ 81.

In spherical coordinates, the volume element is given by:

dV = ρ^2 sin φ dρ dθ dφ

where ρ is the radial distance, φ is the polar angle (measured from the positive z-axis), and θ is the azimuthal angle (measured from the positive x-axis).

Substituting into the integral, we get:

∫φ=0 to φ=π ∫θ=0 to θ=2π ∫ρ=0 to ρ=9 ρ^2 sin φ (ρ^2) dρ dθ dφ

= ∫φ=0 to φ=π ∫θ=0 to θ=2π ∫ρ=0 to ρ=9 ρ^4 sin φ dρ dθ dφ

= ∫φ=0 to φ=π ∫θ=0 to θ=2π (1/5)(9^5) sin φ dθ dφ

= (2π/5)(9^5)(-cos φ)|φ=0 to φ=π

= (2π/5)(9^5)(-(-1 - 1))

= (4π/5)(9^5)

≈ 114413.73

Therefore, the value of the triple integral is approximately 114413.73.

traveled 1/5 miles in 3/2 hour. how many in 1 hour. show model fraction representation

Answers

a)Traveled 0.3 miles in 1 hour.

b) The fraction representation is 3/10 miles per hour.

a) To find out how many miles the person traveled in 1 hour, we need to divide the distance traveled by the time taken.

Distance traveled = 1/5 miles

Time taken = 3/2 hours

To make it easier to divide, we can convert the time taken to a fraction with a common denominator of 10:

3/2 = 15/10

Now we can divide the distance by the time:

1/5 ÷ 15/10 = 1/5 x 10/15 = 2/15

This tells us that the person traveled 2/15 miles in one-tenth of an hour (i.e., 6 minutes).

To find out how many miles per hour they traveled, we can convert the fraction to a rate by multiplying it by the reciprocal of the time fraction (i.e., 10/3):

2/15 x 10/3 = 2/9

Therefore, the person traveled 2/9 miles per hour.

b) To write this as a model fraction representation, we can express it as a single fraction:

2/9 = 3/10 (rounded to the nearest tenth)

So the person traveled at a rate of 3/10 miles per hour.

How many ounces of fudge does she give her sister?

Answers

The amount of fudge the student gives to her sister, which is (1/2) of her remaining fudge, calculated using fractions is 16 ounces

What is a fraction?

A fraction is a representation of a part of a whole, by setting the quantity representing the part as the numerator and the quantity representing the whole as the denominator with both quantities separated by the fraction bar.

Part of the question obtained from a similar question posted online can be presented as follows;

The amount of fudge the student has = 3 pounds

The amount of fudge the student eats = 1 pound of the fudge

Required; The amount of fudge the student has left

The amount of fudge the student has left = 3 - 1 = 2 pounds

The fraction of the remaining fudge the student gives to her sister = (1/2)

Therefore;

The amount of fudge the student gives her sister = (1/2) × 2 pounds = 1 pound

1 pound = 16 ounces

The amount of fudge she gives her sister in ounces = 16 ounces

Then, write a thoughtful and considered posting that explains your response to the following writing prompts about the short story. Explanation: Fundamentally, in literature, Realism is the portrayal of life with fidelity. It is not concerned with idealization--but has a preoccupation with attempting to illustrate things as they are (Walcott, Tagore) and not as they should be (Zeami Motokiyo, Marie de France). As a rule, realism is not concerned with presenting the supra-normal or transcendental (Euripides, Ovid). Writing Prompts: 1) Illustrate and explain two elements of Realism as described in the lecture slides with examples from Tagore's short story. 2) But theories such as Realism don't appear out of a vacuum; literary artists have been preoccupied with illustrating their world in writing throughout history.
