You have a student who says the sum of 3/4 and 5/6 is 4/5. Do you agree with them? Explain and solve this problem. Draw a model and explain how to solve this problem. Explain why we need common denominators.

Answer: $60.00

Step-by-step explanation: If we want to find how much money she makes in 12 hours, we must use the information we got for how much she makes in 1 hr, and apply that to make a proportional relationship. So, it would look like this:

[tex]\frac{5}{1}[/tex] = [tex]\frac{?}{12}[/tex]

Now, using cross multiplying, we multiply 1 x 12 and 5 x 12 to get $60. I hope this helped.

What are linear models?

A response variable can be described in terms of a linear combination of predictor variables using linear models. The response ought to be continuous and at least roughly regularly distributed. Although these models are widely used, they are unable to handle clearly discrete or skewed continuous data.

In the table, we see that as x increases, y values change in a steady manner. The slope of this function is approximately 1860.

We use straight lines to visually illustrate linear relationships. Typically, a linear model has two parameters: the slope, also known as the growth factor or rate of change, and the y-intercept, often known as the beginning value. The linear model can be expressed as a linear function, y = mx + b or y=mx+b, where m is the slope and b is the y-intercept.

So, we get the slope as 1860.

3)  The solution at the specified value of the independent variable is 1490.991

In practical contexts, derivatives frequently represent the rates of change of physical quantities, and the differential equation establishes a relationship between the two. As a result of the frequent occurrence of these correlations, differential equations are widely employed in a wide range of disciplines, including engineering, physics, economics, and biology.

Only the simplest differential equations can be resolved explicitly, but many aspects of a given differential equation's solutions can be determined without doing an exact calculation.

1) The differential equation is: dP/dt=kP

Here k is the proportionality constant

2) Now, we have to solve the differential equation on dP/dt=kP

∫dP/P=∫kdt+lnP₀

lnP₀=kt+lnP₀

lnP/P₀=kt

P=P₀[tex]e^{kt}[/tex]

Here P₀ is the constant of integration.

P(t)=P₀[tex]e^{kt}[/tex]

And they have given that,

P(0)=8000=P₀e⁰

P₀=8000

P(1)=5200

5200=8000[tex]e^{k}[/tex]

k=-2log(2)+log(3)≈ -0.28

Therefore, the required function is:

Answer:

|z| = 5

Step-by-step explanation:

Complex numbers can be represented on an Argand diagram.

The x-axis is called the real axis and the y-axis is called the imaginary axis.

The complex number  z = x + iy  is represented on the diagram by the point  P(x ,y), where x and y are Cartesian coordinates.

Therefore, the complex number z = -5 can be represented on the Argand diagram by the point:

The absolute value of a complex number is the magnitude of its corresponding vector.

For a complex number  z = x + iy,  the absolute value is given by:

[tex]|z|=\sqrt{x^2+y^2}[/tex]

Therefore, the absolute value of complex number z = -5 is:

[tex]\implies |z|=\sqrt{(-5)^2+(0)^2}[/tex]

Hello,

I hope you and your family are doing well!

To solve this problem, you need to set up a proportion using the information given in the problem. Let x represent the number of miles the family will travel during the next 4 hours. The proportion will look like this:

318 miles / 6 hours = x miles / 4 hours

To solve for x, you can cross-multiply and solve the equation:

318 miles / 6 hours = x miles / 4 hours

6 hours * 318 miles = 4 hours * x miles

1848 miles = 4x miles

x = 462 miles

Therefore, if the family continues at the same rate, they will travel a total of 462 miles during the next 4 hours.

Using the exponent's rule we know that x = 5.

Exponentiation is a mathematical process that involves the base b and the exponent or power n.

It is represented as bn and is pronounced as "b to the n."

A number's exponent indicates how many times to multiply that particular number.

It appears as a little number above and to the right of the basic number.

For instance, 82 = 8 x 8 = 64.

(The exponent "2" instructs us to multiply by two and use the number eight.)

Another illustration is 53 = 5 * 5 * 5 = 125.

So, we have: 2ˣ = 32

We know that:

2 * 2 * 2 * 2 * 2 = 32

2 is multiplied 5 times which means:

2⁵ = 32

Hence, x = 5.

Step-by-step explanation:

We can conclude that.

[tex]r*t_1=p_{reg}[/tex]   is the gross pay from his regular hours.

[tex]1.5r*t_2=p_{ovt}[/tex] is the gross pay from his overtime hours.

So all together we can say

[tex](r*t_1)+(1.5r*t_2)=p[/tex]

We are looking for his hourly rate.

Lets solve for [tex]r[/tex].

Multiply the terms in the parenthesis.

[tex]rt_1+1.5rt_2=p[/tex]

Factor [tex]r[/tex] out of [tex]rt_1[/tex].

[tex]r(t_1)+1.5rt_2=p[/tex]

Factor [tex]r[/tex] out of [tex]1.5rt_2[/tex].

[tex]r(t_1)+r(1.5t_2)=p[/tex]

Factor [tex]r[/tex] out of [tex]r(t_1)+r(1.5t_2)[/tex].

[tex]r(t_1+1.5t_2)=p[/tex]

Divide each term in [tex]r(t_1+1.5t_2)=p[/tex] by [tex]t_1+1.5t_2[/tex] and simplify.

[tex]\frac{r(t_1+1.5t_2)}{t_1+1.5t_2} =\frac{p}{t_1+1.5t_2}[/tex]

Simplify the left side.                                                                              Cancel the common factor of [tex]t_1+1.5t_2[/tex]

[tex]r=\frac{p}{t_1+1.5t_2}[/tex]

Now we have an equation to find his regular hourly rate.

We are given

[tex]p=16203[/tex]

[tex]t_1=40[/tex]

[tex]t_2=20[/tex]

Lets plug these numbers into our equation for [tex]r[/tex].

[tex]r=\frac{16203}{40+1.5*20}[/tex]

[tex]r=\frac{16203}{70}[/tex]

Answer

2617.

Step-by-step explanation

To estimate the number of people that can fit into a circular arena with a diameter of 100 yards, we first need to find the area of the arena. To do this, we can use the formula for the area of a circle, which is equal to pi times the radius squared. Since the diameter of the arena is 100 yards, the radius would be half of that, or 50 yards. Plugging this value into the formula for the area of a circle, we get:

Area = pi * 50^2

Since pi is approximately equal to 3.14, we can plug this value into the equation to get:

Area = 3.14 * 50^2

This simplifies to:

Area = 3.14 * 2500

Which gives us an area of approximately 7850 square yards.

Since one person requires a personal space of 3 square feet, we can divide the total area of the arena by 3 to find the number of people that can fit in the arena. This gives us:

7850 square yards / 3 square feet/person = 2616.666... people

Rounded to the nearest whole number, this means that approximately 2617 people could fit in the circular arena with a diameter of 100 yards.

To find the slope you divide the rise by the run. Rise being how many units it goes up or down) (run being how many units it goes to the side).

In this case the rise is -2 and the run is -1.

See in the picture, for every 2 units the line goes down, it moves one unit to the right.

What is value ?

Value in mathematics can refer to a number of closely related ideas. A mathematical value can generally be any specific mathematical object. This is most frequently a number in elementary mathematics, such as a real number like or an integer like 42.

Depending on where it is in the number, each digit has a different value, which is referred to as value. We figure it out by multiplying the digit's place value by its face value. Place value plus face value equals value. Consider the number 45, for example. Here, the fourth digit is in the tens column.

If triangle is isosceles it means the two sides and angles are equal

∴ BC = AC
