Julia has lower rate than anna by 0.375 miles/ hour

A rate is a ratio that is used for comparing two different kinds of quantities which have different units. On the other hand, the unit rate illustrates how many units of quantity correspond to the single unit of another quantity. We say that when the denominator in rate is 1, it is called unit rate. In fact, unit rate is said to be the amount of something in each unit or per unit. Let us understand this using some examples:

40 miles/2 hours = 20 miles/hour, Unit rate is 20 miles per hour

160 words/4 minutes = 40 words/minutes, Unit rate is 40 minute per minute

To compare the unit rate of the two riders, we need to determine the number of miles per hour for each of them.

For Anna, the unit rate is 20 miles / 1 1/3 hour = 15 miles/hour.

For Julia, the unit rate is 246 miles / 16 hours = 15.375 miles/hour.

In mathematics, a percentage is a number of ratio that is stated as a portion of 100. Also occasionally used are the abbreviations "pct.," "pct," with "pc." To denote it, though, the percent symbol "%" is frequently employed. The % amount has no dimensions. Because percentages contain a numerator of 100, they are effectively fractions. A number should be followed by the % sign (%) to show that it represents a percentage. For instance, someone would receive a 75% grade if you properly solved 75 out of 100 questions on a test. To determine percentages, divide the amount of money by the total, and then multiply the result by 100. The percentage is calculated by multiplying the ratio (value/total) by 100%.

Here,

a =2001/100 * (b+c)

and

b= 87/100*c

thus putting value of b in a

=>a = 2001/100*(87/100*c + c)

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

f ( x ) = 4 − ( x + 3 )^5

To make the equation legible, we need to rewrite it

So, we have the following representation

f(x) = 4 − (x + 3)⁵

Also from the question, we have

f(-3) - 2

This means that the value of x is -3, and we calculate f(x) when x = -3

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

f(x) - 2 = 4 − (x + 3)⁵ - 2

So, we have the following equation

f(-3) - 2 = 4 − (-3 + 3)⁵ - 2

There are constants to add or subtract to both sides of the equation

However, there is no factor to multiply or divide from both sides of the equation

So, we have the following representation

f(-3) - 2 = 4 − (0)⁵ - 2

The volume of the cube before it was melted is greater than 49cm^3

The amount of melted liquid left after making the cone is 49 cm^3.

A cone is a three-dimensional shape that has a circular base and a single vertex or point. The amount of liquid remaining after making a cone can be calculated by comparing the volume of the cone to the volume of the cube.

The volume of a cone can be calculated using the formula:

V = (1/3) * pi * r^2 * h

Where V is the volume of the cone, pi is a mathematical constant (approximately 3.14), r is the radius of the circular base, and h is the height of the cone.

However, we don't have information about the radius or height of the cone, we only know the volume of melted liquid left after making the cone is 49 cm^3.

We can use this information to determine the volume of the cube before it was melted and compare it with the volume of the cone.

The volume of a cube can be calculated using the formula:

V = s^3

Where V is the volume of the cube, s is the length of one side of the cube.

Let's call Vc the volume of the cube before it was melted and Vcon the volume of the cone

Vc - Vcon = 49 cm^3

Therefore, the volume of the cube before it was melted is greater than 49cm^3

The additive inverse of 4 is -4. This means that when 4 is paired with -4, the two numbers cancel each other out and the result is 0.

The additive inverse of a number is the opposite of that number. For example, the additive inverse of 4 is -4. This means that when two numbers are added together and one of them is 4 and the other is -4, the result will be 0. This is because the two numbers cancel each other out. The same is true for any number and its additive inverse. For example, 8 and -8 added together will also result in 0. Additive inverses are an important part of algebra and can be used to solve equations. By understanding the concept of additive inverses, you can easily manipulate equations and solve for unknowns.

This text describes a scenario where someone has taken out a loan of $4050. The loan has an interest rate of 6.5%, which means that the borrower will have to pay an additional 6.5% of the loan amount as interest. The loan is taken for a period of 2 years, which is the time frame during which the borrower has to repay the loan.

The question being asked is about the interest that will be accumulated on this loan. Interest accumulation refers to the increase in the amount of money that the borrower owes due to the interest that is being charged on the loan.

In this case, we need to calculate the total amount of interest that will be charged over the 2-year period, based on the loan amount and interest rate.

To calculate the interest accumulated on this loan, we can use the following formula:

Interest = Principal * Rate * Time

Where:

- Principal = the amount borrowed (in this case, $4050)

- Rate = the interest rate (in this case, 6.5% or 0.065 as a decimal)

- Time = the length of the loan in years (in this case, 2 years)

Plugging in the values, we get:

Interest = $4050 * 0.065 * 2

Interest = $527.25

So the interest accumulated on this loan is $527.25. This means that the borrower will have to pay back a total of $4577.25 ($4050 + $527.25) over the 2-year period.

Around 100 hours will take for both vats to contain the same amount of liquid.

How do you calculate the rate of evaporation of a liquid?

The equation indicates that the evaporation rate,

W = (95+0.425*V)*(Pw-Pa)/Y, where W is the evaporation rate, V is the air velocity at the water surface,  Pw is the saturation vapor pressure at water temperature.

To find out how many hours it will take for both vats to contain the same amount of liquid, we need to compare the rates at which the liquid is evaporating from each vat.

We can set up the following equation:

(35 - x) / 0.25 = (40 - x) / 0.35

where x is the amount of liquid in both vats at the time they reach the same level.

We can then solve for x by multiplying both sides by 0.25 and 0.35 and then subtracting one equation from the other:

35 - x = 40 - x

x = 5

So, both vats will contain 5 liters of liquid at the time they reach the same level.

To find out how many hours it will take to reach this point, we can use the rate of evaporation for either vat.

For Vat A:

35 - 5 = 30 liters

30 liters / 0.25 liters/hour = 120 hours

For Vat B:

40 - 5 = 35 liters

35 liters / 0.35 liters/hour = 100 hours

So, It will take around 100 hours for both vats to contain the same amount of liquid.

The midpoint theorem is used in a variety of mathematical fields, but it is primarily used in geometry and algebra.

In geometry, the midpoint theorem is used to find the midpoint of a line segment, which is the point that is exactly halfway between the two endpoints of the segment. The theorem states that the coordinates of the midpoint of a line segment can be found by averaging the coordinates of the endpoints.

For example, if the endpoints of a line segment have coordinates (x1, y1) and (x2, y2), the coordinates of the midpoint would be ((x1 + x2)/2, (y1 + y2)/2).

In algebra, the midpoint theorem can be used to find the equation of a line when the coordinates of the endpoints of a line segment are known. The equation of a line can be represented in the form of y = mx + b, where m is the slope and b is the y-intercept.

The slope of the line can be found by taking the difference of the y-coordinates of the two endpoints divided by the difference of the x-coordinates of the two endpoints. The y-intercept of the line can be found by using the midpoint of the line segment and the slope of the line.

In Calculus, the midpoint theorem is used in optimization problems. Optimization problems are used to find the maximum or minimum value of a function.

The midpoint theorem is used to find the critical points of the function, which are the points where the function reaches its maximum or minimum value. The critical points are found by taking the derivative of the function and equating it to zero.
