Answer:

2/(1/4) = 8 1/4th gallons to fill the container and 1/8 * x = 8/8 (x=8) times you can fill the tank with 1/4th gallon

Step-by-step explanation:

First let's answer the first part of the question: what fraction of the container is filled?

If there is 1/4 a gallon of water in the container which holds 2 gallons, we can show this by adding 0/4 to 1/4 to get 1/8 as the fraction of the container filled. (Or just double the denominator for both gallons instead of 1)

To represent this with a multiplication equation, we will take the holding of the container which is 2 gallons

1/8 times x = how many times you can fill the container with 1/4 gallon of water (which is 8 total)

and then our division which is

2 divided by 1/4 = how many shares of water can fit in the container

I hope this helps :)

Answer: what's so urgent?

Step-by-step explanation:

The time to reach 125 feet is 1.3 seconds, the time to reach a maximum height of 147.52 ft is 2.5 seconds

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

h(t) = -16t^2 + 79t + 50

To do this, we set h(t) = 125

So, we have

-16t^2 + 79t + 50 = 125

Using a graphing tool, we have

t = 1.3

So, the time taken is 1.3 seconds

We have

h(t) = -16t^2 + 79t + 50

Differentiate and set to 0

-32t + 79 = 0

So, we have

32t = 79

This gives

t = 2.46875

t = 2.5

Next, we have

h(2.46875) = -16 * 2.46875^2 + 79 * 2.46875 + 50

Evaluate

h(2.46875) = 147.52

Hence, the maximum height is 147.52 ft

122 degrees Fahrenheit is equal to 50 degrees Celsius.

Fahrenheit is a temperature scale where water freezes at 32 degrees and boils at 212 degrees under standard atmospheric pressure.

It is primarily used in the United States, the Bahamas, Belize, and the Cayman Islands.

For example, a typical comfortable room temperature of 72 degrees Fahrenheit would be 22.2 degrees Celsius on the Celsius scale.

Using the formula F = (9/5 x C) + 32, we can find the temperature in Fahrenheit when the temperature is 50 degrees Celsius.

Answer:

Step-by-step explanation:

You want the measures of the angles (5x+10°) and (10x+50°) that are divisions of an angle marked as a right angle.

The angle addition theorem tells you the whole is the sum of its parts. Here, the right angle in the diagram is divided into two parts, marked 5x+10° and 10x+50°. The measure of the right angle is the sum of these parts:

  90° = (5x +10°) +(10x +50°)

  30° = 15x . . . . . . . subtract 60°

  2° = x . . . . . . . . . divide by 15

Using this value for x, we find the angle measures to be ...

  5x+10° = 5(2°) +10° = 10° +10° = 20°

  10x+50° = 10(2°) +50° = 20° +50° = 70°

240 full glasses of juice can be poured from the large can of juice.

Calculating the volume of the large can of juice and the volume of the tiny glass is necessary to answer this problem. The volume of the can must then be divided by the volume of the glass to determine how many glasses can be filled.

The formula V = r2h, where r is the radius and h is the height, determines the volume of a cylinder.

The radius for the large juice can is equal to half the diameter, or r = 6 inches. It is 15 inches tall. Hence, the huge can's volume is as follows:

V large is equal to (1620)(6)2(15) cubic inches.

The radius for the little glass is equal to half its diameter, or 1.5 inches. It is 3 inches tall. Hence, the little glass's volume is as follows:

V small is equal to 1.5 x 2 x 3 or 6.75 cubic inches.

We divide the volume of the large can by the volume of the tiny glass to determine how many glasses can be filled:

V large/V small is equal to (1620)/(6.75), or 240.

As a result, the enormous can of juice can be used to fill 240 glasses to the brim.

52 applicants apply, 30 employees will be hired and at least 30 of them will pass the background test.

To determine how many applicants need to apply to meet the hiring target, we need to work backwards from the desired number of hires.

Let X be the total number of applicants needed to hire 30 new employees.

Out of all applicants, 10% do not meet the base business requirements. Therefore, the number of applicants who do meet the base business requirements is:

[tex]$0.9X$[/tex]

Out of these applicants who meet the base business requirements, 12% do not pass the pre-screening assessment. Therefore, the number of applicants who pass the pre-screening assessment is:

[tex]$0.88(0.9X) = 0.792X$[/tex]

Out of these applicants who pass the pre-screening assessment, 23% do not show up for the interview. Therefore, the number of applicants who show up for the interview is:

[tex]$0.77(0.792X) = 0.6108X$[/tex]

Out of these applicants who show up for the interview, 5% fail the background test. Therefore, the number of applicants who pass the background test is:

[tex]$0.95(0.6108X) = 0.58026X$[/tex]

Since we need to hire 30 new employees, we can set this equal to 30 and solve for X:

[tex]$0.58026X = 30$[/tex]

[tex]$X \approx 51.74$[/tex]

Therefore, Company B needs approximately 52 applicants to apply to meet their hiring target.

To meet the hiring target, Company B will need to ensure that at least 30 employees pass the background test. From the above calculations, we know that 0.58026X applicants pass the background test. Therefore, we can solve for X:

[tex]$0.58026X = 30$[/tex]

[tex]$X \approx 51.74$[/tex]

The terms in the numerator and simplify the fraction, giving us: -2x² - 1/(2x + 1)

A numerator is the part of a fraction that is above the line and indicates how many parts of a whole are being considered. It is the number that is being divided.

The first step in solving this problem is to factor out the numerator. Using the distributive property, we can rewrite the numerator as:

(-3x² + 6x³ - 4 - x) = (-3x² + 6x³ - 4) - x

Now, we can factor out -3x² from the first two terms, giving us:

(-3x² + 6x³ - 4) - x = -3x²(1 + 2x - 4/3x²) - x

We can now divide the numerator and denominator by the common factor of -3x², giving us:

(-1 - 2x + 4/3x²) - (x/(-3x²)) ÷ (2x + 1)

By dividing the numerator and denominator by -3x², we can now cancel out the -3x² terms, leaving us with:

(-1 - 2x + 4/3x²) - (1/3) ÷ (2x + 1)

The next step is to simplify the fraction. To do this, we must multiply the numerator and denominator by the reciprocal of the denominator. In this case, the reciprocal is -1/(2x + 1) giving us:

[(-1 - 2x + 4/3x²) - (1/3)] × (-1/(2x + 1))

Simplifying the numerator yields:

(2x + 1 - 4/3x² + 1/3) × (-1/(2x + 1))

Finally, we can combine the terms in the numerator and simplify the fraction, giving us: -2x² - 1/(2x + 1).

In response to the query, we can state that As a result, $1,154.74 is the interest response to the original query.

To calculate simple interest, divide the principal by the interest rate, the duration, and other variables. The marketing formula is simple return = capital + interest + hours. The easiest way to compute interest is with this method. The most common method for calculating interest is as a percentage of the principal amount. For instance, if he borrows $100 from a buddy and promises to pay it back at 5% interest, he will only pay his portion of the 100% interest. $100 (0.05) = $5. Interest must be paid when you borrow money and must be added to any loans you make. The annual percentage of the loan amount is frequently used to calculate interest. This percentage represents the loan's interest rate.

The equation of the ellipse is (x - 6)² / 4 + (y - 1)² / (16/9) = 1, the center is (6,1), and the directrices are x = 0 and x = 12.

The center of the ellipse is the midpoint of the major axis. The midpoint of the line segment connecting (4,1) and (8,1) is ((4+8)/2, (1+1)/2) = (6,1). Therefore, the center of the ellipse is (6,1).

The distance between the center and one of the vertices (say, (8,1)) is the length of the semi-major axis, a. This distance is (8-6) = 2. Therefore, the semi-major axis is a = 2.

The eccentricity, e, is given as 1/3.

The distance between the center and one of the foci, c, is related to the semi-major axis and eccentricity by the equation c = ae. Plugging in the values we know, we get c = (1/3)(2) = 2/3.

We can write the equation of the ellipse in standard form:

(x - 6)² / 2² + (y - 1)^2 / b² = 1

where b is the semi-minor axis. We can solve for b using the relationship between the semi-major axis, semi-minor axis, and eccentricity:

So the equation of the ellipse is:

(x - 6)² / 4 + (y - 1)² / (16/9) = 1

The directrices are located a distance of a² / c = (2²) / (2/3) = 6 units away from the center along the major axis. These are the lines x = 6 - 6 = 0 and x = 6 + 6 = 12.
