Answer:

140cm

Step-by-step explanation:

We first have to change 2.4 meters into centimeters. And the formula for that is (x)m = (x)cm x 100.

So 2.4 x 100 = (x)m. We can solve this by moving the "." two times to the right and we will get 2.4m = 240cm.

The next step is to divide it by twelve because Billy wants to share it with 12 friends. 240cm/12 = 20cm per person.

Then we have to multiply 20 with 7 to see how many centimeters 7 friends would get.

20*7 = 140. So the answer is 140cm.

The Dylan sister Jane received 1/5 marbles, which is a part of 25 if the Dylan has a total of 25 marbles.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

The total number of marbles Dylan has = 25

The total number of marbles Dylan gave to his sister = 5

If we choose one marble out of 25 = 1/25

If we choose 5 marbles = 5(1/25) = 1/5

Thus, the Dylan sister Jane received 1/5 marbles, which is a part of 25 if the Dylan has a total of 25 marbles.

Answer:

Slavery caused the Civil War because colored people were being treated unfairly by the South and the North didn't like that. States rights is when a state abides by its own rules. Missouri was allowed to enter the Union as a slave state. California had to decide if they were going to be a slave state or a free state.

Step-by-step explanation:

Slavery was the root of the Civil War in the United States. Following the election of Republican and abolitionist Abraham Lincoln in 1861, southern governments grew fearful of his political beliefs. His victory sparked heated debate in the slave-dependent southern states. Because of the incoming president's future activities, states were planning to secede. These republics were heavily reliant on agriculture, therefore ending slavery would be disastrous. After Lincoln rejected their judgment, the Union and Confederacy declared war on one other. The Confederacy battled and killed to keep slavery alive, but the union won four years later. Abraham Lincoln fought for black people's freedom and human rights while simultaneously fighting to keep the Unified States united. This battle not only ended slavery, but it also brought the states together and preserved a strong country developing together.In the 1860 presidential election, Abraham Lincoln campaigned for president and won, becoming the first republican candidate to do so. His election, on the other hand, brought terrible news to the southern states, which were heavily reliant on agricultural and used slavery to increase revenues. "By and large," according to the book America Past and Present, "By and large, by and large, by and large, by and The civil war began in April 1861, when Southern states attempted to secede from the nation after Abraham Lincoln's election, and concluded in 1865, when the northerners (the Union) triumphed.  However, the most crucial reason for the outbreak of the war was that Republican Abraham Lincoln won the election of 1860, and his views on slavery were diametrically opposed to those of the southerners. His election sparked such outrage in the southern states that the possibility of going to war to avoid being linked with his political ideals was floated.

Answer:

4n^2.

Step-by-step explanation:

Working from left to right in the square parentheses:-

[6m² x 6n² ÷ 9mn ÷ 2m]²

= [(36m^2n^2 / 9mn) / 2m]^2

= (4mn / 2m)^2

= (2n)^2

= 4n^2.

[6m² x 6n² ÷ 9mn ÷ 2m]²

the simplest form.

Step-by-step explanation:

Since the directrices are vertical lines:

Since we already know our directrices are at the lines [tex]x=\pm2[/tex] and we know that [tex]c=\pm6[/tex] from our foci, we can solve for the value of [tex]a^2[/tex]:

[tex]x=\frac{a^2}{c}\\\\2=\frac{a^2}{6}\\\\12=a^2[/tex]

This allows us to solve for the value of [tex]b^2[/tex]:

[tex]a^2+b^2=c^2\\\\12+b^2=6^2\\\\12+b^2=36\\\\b^2=24[/tex]

Step-by-step explanation:

Each plane has a starting altitude and a fixed rate of climb. Its altitude at some time t will be the sum of the starting altitude and t times the rate of climb.

__

  altitude = starting altitude + t × rate of climb

  a(t) = 4000 +35.25t

  b(t) = 2427 +65.5t

The planes will be at the same altitude at the same time when ...

  a(t) = b(t)

  4000 +35.25t = 2427 +65.5t

  1573 = 30.25t . . . . . . . . . . subtract 2427+35.25t

  52 = t . . . . . . . . . . . . . divide by 30.25

That altitude is ...

  a(52) = 4000 +35.25×52 = 4000 +1833 = 5833

52 seconds will pass before the planes are at the same altitude.

Their altitude then will be 5833 feet.

Rewrite the whole as a fraction using  5  as the denominator :

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

When a fraction equals zero :

4.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now, to get rid of the denominator, I multiply both sides of the equation by the denominator.

Here's how:

 5y-4x-47

 ———————— • 5 = 0 • 5

    5    

Now, on the left hand side, the  5  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  5y-4x-47  = 0

Equation of a Straight Line

4.2     Solve   5y-4x-47  = 0

CalderonJ recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx + b" is the formula of a straight line drawn on a Cartesian coordinate system in which "y" is the vertical axis and "x" is the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  5y-4x-47  = 0 and calculate its properties

Notice that when x = 0 the value of y is 47/5 so this line "cuts" the y axis at y= 9.40000

 y-intercept = 47/5  =  9.40000

Calculate the X-Intercept :

When y = 0 the value of x is 47/-4 Our line therefore "cuts" the x axis at x=-11.75000

 x-intercept = 47/-4  = -11.75000

Calculate the Slope :

The slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 9.400 and for x=2.000, the value of y is 11.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 11.000 - 9.400 = 1.600 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     =  1.600/2.000 =  0.800

(5+3y) (x+3)

first of all you bracket by (5x+15)(3xy+9y). and you start fact as follows by 5(x+3y) 3y(x+3)after here you take (5+3y) (x+3)

Answer:

(x+3)+(5+3y)

Step-by-step explanation: In the equation, when you have four terms you group like terms. So 5x+15 by itself and work it out which you will get 5(x+3) and do the same for 3xy+9y answer is 3y(x+3).

Then you will say 5(x+3)+3y(x+3) and then you'll

5(x+3)/(x+3)=5 because you will cancel the (x+3) so the answer would be 5

You will do the same for 3y(x+3)/(x+3)

you will get 3y

Finally, you will take the first equation which is (x+3), and then you'll use the last equation which is (5+3y)

So that's how you will get (x+3)+(5+3y)

Based on the calculations, the function which best models the data in the graph is y = 10.1x + 101.

Mathematically, the equation of a line in standard form is given by this formula:

y - y₁ = m(x - x₁)

Where:

In order to determine the function which best models the data in the graph shown in the image attached below, we would calculate the slope of the data by using this formula:

[tex]Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}\\\\Slope = \frac{202\;-\;101}{10\;-\;0}\\\\Slope = \frac{101}{10}[/tex]

Slope = 10.1.

For the function, we have:

y - y₁ = m(x - x₁)

y = 10.1(x - 0) + 101

y = 10.1x + 101.
