Answer:

There's a very simple way to solve this kind of problem. All we have to do is change the percent to a decimal and multiply it by her current grade.

81 × .15 = 12.15

For our purposes, we'll just round it down to 12. But anyway, raising her grade by 15% would mean raising it by 12 points.

81 + 12 = 93

This would give her an average of 93, not 95. She'd need to raise her grade 18% from 81 to get to her goal.

Jana's sole day off from work is Friday of the second week. According to the Fair Labor Standards Act, Jana is entitled to overtime pay because she works more than 40 hours per week.

A minimum wage and "time-and-a-half" overtime pay are guaranteed under the Fair Labor Standards Act of 1938, 29 U.S.C. 203 (FLSA), a piece of labor legislation in the United States.

Additionally, it forbids using children for "oppressive child labor."

Jana, for instance, has a two-week timetable.

She puts in nine hours a day, or 8 to 5, throughout the first week of work. She works 8.75 hours per day, Monday through Thursday, from 8 to 4:45 during the second workweek.

The second week's Friday is her only day off from work. Because Jana works more than 40 hours each week, she is entitled to overtime pay under the Fair Labor Standards Act.

The Silmarillion has 130,115 words, so if about 300 words fit on a page, it would take about 433 pages to print. However, the actual number of pages would be slightly more.

The Silmarillion is a collection of J.R.R. Tolkien's mythology for Middle-earth, and it contains a vast amount of detail. The book has 130,115 words, which is a lot of text to fit on a page. If about 300 words fit on a page, then the Silmarillion would take about 433 pages to print. However, some pages would need to be longer to accommodate longer lines of text. For example, the page with the Elvish names would need to be much longer than the average page. So, the actual number of pages in a printed book of The Silmarillion would be slightly more than 433.

Answer:

960 ounces in 1 day

(Sorry for a late response, I just logged on)

Step-by-step explanation:

Most of that information is negligable (not important) besides 8 ounces in 12 minutes.

so an hour is 60 minutes, if we multiply both parts of the problem by 5 we get

40 ounces in 1 hour

a day is 24 hours, so if we multiply both sides by 24 well get our answer

960 ounces a day

-- Gage Millar, Algebra 1/2 tutor

Answer:

960 ounces

Step-by-step explanation:

First, let's find how much water will drip in an hour (60 minutes), so we can make an equation:

8/12 = x/60

And if you multiply both sides of the equation by 60 you will get 8*5 = x which is 40. So, we know that in one hour, 40 ounces of water will drip from the bathroom faucet. To find how much water will drip in a day, just multiply 40 by 24 (since there are 24 hours in a day). That would result in 960.

Answer: The probability is 50%.

Step-by-step explanation: The probability that both are girls if the older child is a girl can be calculated through probability. First, we know that there are two genders the child can be, male or female. When we have 2 possible outcomes, the probability of each outcome is 50%. We know the first child is a girl, and that the second child has a 50% chance of being a girl, so the probability is 50%.

Recall that to find the theoretical probability we use the following expression:

Since the jar contains 20 yellow marbles, 55 green marbles, and 25 purple marbles, then the jar contains 20+55+25=100 marbles. Therefore, the theoretical probability of picking a green or a yellow marble is:

Cumulative frequency refers to the total number of observations or individuals that fall at or below a certain value in a dataset. In this case, a cumulative frequency of 12 (cf = 12) for a test score of 72 means that there are 12 people who scored at or below a score of 72 on the test. Options a, b, and d are incorrect interpretations of the cumulative frequency.

Option a suggests that 72 people scored at or below a score of 12, which is not accurate based on the given information. Option b implies a percentage, which is not directly indicated by the cumulative frequency value. Option d suggests a percentage of people scoring at or below a score of 72, which again is not supported by the information provided.

Answer:

Growth rate is 17%

2025 value is $76

Step-by-step explanation:

Here, we want to determine the annual growth rate

The general equation form is;

F = l( 1 + r)^n

where F is the future value

I is the initial value

r is the growth rate

n is the numbering years

To get the growth rate, we simply equate what we have in the bracket to 1 + r

Thus;

1 + r = 1.17

r = 1.17-1

r = 0.17

0.17 is same as 17/100 which is same as 17%

Secondly, we want to get the value of the book in 2025

What we have to do here is to substitute (2025-2000) for t which is 25

We have;

V(t) = 1.50(1.17)^25

V(25) = 75.986 which is approximately 76

We will see that the annual growth rate is of 17%, and in the year 2025, the value will be $75.99.

Exponential growth functions:

A general exponential growth can be written as:

f(x) = A*(1 + r)^x

Where A is the initial value and r is the growth rate. Now we can rewrite our function to get:

V(t) = 1.50*(1 + 0.17)^t

Then you can see that the growth rate is 0.17, or 17% in percentage form (to get it just multiply it bt 100%).

To get the value of the comic book in 2025 you just need to evaluate the function in t = 25 (25 years after the 2000).

V(25) = 1.50*(1 + 0.17)^25 = 75.99

So the value in 2025 is $75.99

Answer:

No se bro suerte con eso V:

Step-by-step explanation:

The volume of the solid e, using spherical coordinates, is -32π/243 (or approximately -0.418π). Note that the negative sign indicates that the orientation of the solid e is flipped or inverted.

What is spherical coordinates?

Spherical coordinates are a system of coordinates that represent points in three-dimensional space using three parameters: ρ (rho), θ (theta), and φ (phi). Spherical coordinates are particularly useful when working with problems involving spherical symmetry.

To evaluate the volume using spherical coordinates, we need to express the cone and sphere equations in terms of spherical coordinates. The spherical coordinates consist of three parameters: ρ (rho), θ (theta), and φ (phi).

The conversion from Cartesian coordinates (x, y, z) to spherical coordinates (ρ, θ, φ) is as follows:

x = ρsin(φ)cos(θ)

y = ρsin(φ)sin(θ)

z = ρcos(φ)

First, let's express the cone equation, θ = π/3, in spherical coordinates. Since the cone is defined by a constant value of θ, we have:

θ = π/3

Next, let's express the sphere equation, x² + y² + z² = 4z, in spherical coordinates. Substituting the spherical coordinate expressions into the Cartesian equation, we get:

(ρsin(φ)cos(θ))² + (ρsin(φ)sin(θ))² + (ρcos(φ))² = 4ρcos(φ)

Simplifying this equation, we have:

\(ρ^2sin²(φ)\)(cos²(θ) + sin²(θ)) + \(ρ^2cos²(φ)\) = 4ρcos(φ)

\(ρ^2sin²(φ)\) + \(ρ^2cos²(φ)\)) = 4\(ρ\)cos(φ)

\(ρ^2\) = 4ρcos(φ)

\(ρ\) = 4cos(φ)

Now, to evaluate the volume, we integrate \(ρ^2sin(φ)\) with respect to \(ρ\), φ, and θ over the appropriate ranges.

The limits of integration are as follows:

\(ρ\): 0 to 4cos(φ)

φ: 0 to π/3

θ: 0 to 2π

The volume element in spherical coordinates is \(ρ^2sin(φ)\)d\(ρ\)dφdθ.

The integral to evaluate the volume becomes:

∫∫∫ \(ρ^2sin(φ)\) dρdφdθ

Integrating with the given limits, the volume of the solid e is:

V = ∫[0 to 2π] ∫[0 to π/3] ∫[0 to 4cos(φ)] ρ^2sin(φ) dρdφdθ

First, let's integrate with respect to ρ:

∫[0 to 2π] ∫[0 to π/3] ∫[0 to 4cos(φ)] ρ^2sin(φ) dρdφdθ

= ∫[0 to 2π] ∫[0 to π/3] [(ρ^3/3)sin(φ)]|[0 to 4cos(φ)] dφdθ

= ∫[0 to 2π] ∫[0 to π/3] [(64/3)cos^4(φ)sin(φ)] dφdθ

Next, let's integrate with respect to φ:

∫[0 to 2π] ∫[0 to π/3] [(64/3)cos^4(φ)sin(φ)] dφdθ

= ∫[0 to 2π] [-16cos^5(φ)]|[0 to π/3] dθ

= ∫[0 to 2π] (-16/243) dθ

= (-16/243)θ| [0 to 2π]

= (-16/243)(2π - 0)

= (-32π/243)

Therefore, the volume of the solid e, using spherical coordinates, is -32π/243 (or approximately -0.418π). Note that the negative sign indicates that the orientation of the solid e is flipped or inverted.

Answer: 1.8 L/h

Step-by-step explanation:

To convert the rate of water dripping from a tap from millilitres per second (ml/sec) to litres per hour (L/h), we need to use conversion factors.

Step 1:

First, let's convert the rate from millilitres per second to litres per second.

There are 1000 millilitres in a litre, so we can divide the rate in millilitres per second by 1000 to get the rate in litres per second:

\(\LARGE \boxed{\textsf{0.5 ml/sec $\div$ 1000 = 0.0005 L/sec}}\)

Step 2:

We can convert the rate from litres per second to litres per hour. There are 3600 seconds in an hour, so we can multiply the rate in litres per second by 3600 to get the rate in litres per hour:

\(\LARGE \boxed{\textsf{0.0005 L/sec $\times$ 3600 = 1.8 L/h}}\)

Therefore, the rate of water dripping from the tap is 1.8 L/h.

The value of S, which represents the length of each side of the square, is 4 miles.

To find the value of S, we need to determine the length of each side of the square. Given that the perimeter of the square is 16 miles, we can use the formula for the perimeter of a square, which is 4 times the length of a side.

Perimeter = 4 × S

Given that the perimeter is 16 miles, we can substitute this value into the equation:

16 = 4 × S

To solve for S, we divide both sides of the equation by 4:

16 ÷ 4 = S

4 = S

Therefore, S, which stands for the square's side lengths, has a value of 4 miles.

So, S = 4 miles.

This means that each side of the square measures 4 miles, and the square has equal sides and right angles at each corner.

Answer to question 1 is   \(\text{y} \le -\frac{2}{5}\text{x}+100\)

=========================================================

Explanation:

The first task is to find the equation of the line through the given points in the table.

Pick any two points you want. I'll pick (0,100) and (50,80)

Determine the slope:

\((x_1,y_1) = (0,100) \text{ and } (x_2,y_2) = (50,80)\\\\m = \text{slope} = \frac{\text{rise}}{\text{run}} = \frac{\text{change in y}}{\text{change in x}}\\\\m = \frac{\text{y}_{2} - \text{y}_{1}}{\text{x}_{2} - \text{x}_{1}}\\\\m = \frac{80 - 100}{50 - 0}\\\\m = \frac{-20}{50}\\\\m = -\frac{2}{5}\\\\\)

The slope is -2/5.

The y intercept is b = 100 because of the point (0,100)

We go from \(\text{y} = m\text{x}+b\) to \(\text{y} = -\frac{2}{5}\text{x}+100\)

Each point from the table is found on this line. For instance, let's check the point (140,44)

\(\text{y} = -\frac{2}{5}\text{x}+100\\\\44 = -\frac{2}{5}*140+100\\\\44 = -56+100\\\\44 = 44\\\\\)

This confirms (140,44)

I'll let you check the other points.

------------------

Any point on the line mentioned represents a scenario where César spends all of the $50.

If he goes above the line, then he'll spend more than $50. If he goes below, he spends less than $50.

This means we want to shade the region below the boundary line \(\text{y} = -\frac{2}{5}\text{x}+100\)

We'll replace the equal sign with a "less than or equal" sign

We arrive at \(\text{y} \le -\frac{2}{5}\text{x}+100\) as the final answer to question 1.

\(Volume = y * (y * 2y+ 4* 2y + y * y+ 4* 7)\)

\(Volume = y(2y^2+ 8y + y^2+ 28)\)

\(Volume = 2y^3+ 8y^2 + y^3+ 28y\)

Collect Like Terms

\(Volume = 2y^3 + y^3+ 8y^2+ 28y\)

\(Volume = 3y^3+ 8y^2+ 28y\)

B. y, y + 7, 2y + 4

\(Volume = y * (y + 7) * (2y + 4)\)

Open brackets

\(Volume = y * (y * (2y + 4)+ 7* (2y + 4))\)

\(Volume = y * (2y^2 + 4y+ 14y + 28)\)

\(Volume = y * (2y^2 + 18y+ 28)\)

\(Volume = 2y^3 + 18y^2+ 28y\)

C. y, y + 2, 2y + 14

\(Volume = y * (y + 2) * (2y + 14)\)

Open brackets

\(Volume = y * (y* (2y + 14) + 2* (2y + 14))\)

\(Volume = y * (2y^2 + 14y + 4y + 28)\)

\(Volume = y * (2y^2 + 18y + 28)\)

\(Volume = 2y^3 + 18y^2 + 28y\)

There's no need to check the last option because option c answers the question.

Hence, the dimension is y, y + 2, 2y + 14
