Answer:

7 hours

Step-by-step explanation:

They won’t nessciarly pass each other while on the tracks becuase Train B is gonna be done with 300 miles so its at the station, it takes 6 hours for the A to reach that station but train B left an hour earlier so that adds another hour

So 7 hours until the two trains meet

Answer:

At the end of the travilling distance and they will take 6 hours

Step-by-step explanation:

After one hour train A is 50mph far but train B is 0 mph. In 2 hours train A is 100 mph and train B is 60 mph. In 3 hours the distance between them is 30 mph. In 4 hours the distance between them will decrease to 20 mph. In 5 hours will be 10 mph the distance between them. So you can see both trains will meet each other at the end of travilling distance so they will arrived at the same time

Answer:

5m to 11m simplified to a ratio would be 5:11.

Step-by-step explanation:

To calculate ratios, try to think of them as fractions instead.

When a ration is expressed in the "a to b" form, you can actually treat it as [tex]\frac{a}{b}[/tex]!

As an example, the ratio of 1 to 2 would be [tex]\frac{1}{2}[/tex]. and the ration of 5 to 9 would be [tex]\frac{5}{9}[/tex].

Hence, the ration of 5m to 11m would be [tex]\frac{5m}{11m}[/tex], which when simplified equals to [tex]\frac{5}{11}[/tex].

Now, we can do the opposite to the fraction! For example, [tex]\frac{10}{19}[/tex] would be equal to 10:19!

Hence, 5m to 11m simplified to a ratio would be 5:11!

Hope this helped!

Answer:

tan 272 < 0 is the correct answer

Step-by-step explanation:

Firstly, we need to understand the quadrant in which we have the angle

Mathematically, angle 272 is on the 4th quadrant

On the 4th quadrant, only the cosine value is positive, sine and tangent values are negative

Hence, we have that tan 272 < 0

is the correct answer

Answer: A. tan 272° < 0

Answer:

$1200

Step-by-step explanation:

Given that:

Monthly subscription fee = $10

Last month's subscribers = 100

THIS MONTH:

New subscribers = 30

canceled subscriptions = 10

Hence,

Total number of subscribers this month :

(Last month subscription + new subscriptions - canceled subscriptions)

(100 + 30 - 10) = 120 subscriptions this month

Hence, amount earned this month will be :

(Total subscriptions this month * monthly subscription fee)

120 * $10 = $1200

The slope of the line is 4 and the y-intercept of the line is -5.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

The given equation of the line is y = 4x - 5. Compare the equation with the general form of the equation,

y = mx + c

y = 4x - 5

Slope m = 4

Y-intercept = -5

Therefore, the slope of the line is 4 and the y-intercept of the line is -5.

Answer:

General Formulas and Concepts:

Algebra I

Step-by-step explanation:

Step 1: Define

5x + 2(x - 3)

Step 2: Simplify

Combining like terms is a process where you combine the terms with the same variable and/or exponent.

Let's say that we have an expression 3p + 3q. We can't combine the like terms, because 3p and 3q have different variables.

Now, what is the distributive property?

The distributive property is a property used for multiplying a monomial by a binomial or trinomial by "distributing" the monomial. The distributive property has a formula, which is:

[tex]\sf{a(b+c)=ab+ac}[/tex]

Here, a got multiplied by b and c.

Similarly, we combine the terms:

[tex]\sf{5x+2(x-3)}[/tex]

Simplify:

[tex]\sf{5x+2x-6}[/tex]

Combine like terms:

[tex]\sf{7x-6}[/tex]

Hence, the simplified answer is 7x - 6.

Answer:

x = 21

y = 114

Step-by-step explanation:

Here, we are to find the values of x and y

Mathematically;

3x - 15 + 6x + 6 = 180

reason for this is that opposite interior angles are supplementary, they add up to 180

9x-9 = 180

9x = 180 + 9

9x = 189

x = 189/9

x = 21

Also;

3x-15 + y + 18 = 180

Reason for this is that angles on a straight line are supplementary

Recall, x = 21

3(21)-15 + y + 18 = 180

63-15 + y + 18 = 180

y = 180-66

y = 114 degrees

Complete Question:

The given line segment has a midpoint at (3, 1). On a coordinate plane, a line goes through (2, 4), (3, 1), and (4, -2).

What is the equation, in slope-intercept form, of the perpendicular bisector of the given line segment?

Answer:

[tex]y = \frac{1}{3}x[/tex]

Step-by-step explanation:

From the question, we understand that the line goes through [tex](2, 4), (3, 1), and\ (4, -2).[/tex]

First, we calculate the slope of the above points

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Where

[tex](x_1,y_1) = (2,4)[/tex]

[tex](x_2,y_2) = (3,1)[/tex]

[tex]m = \frac{1 - 4}{3 - 2}[/tex]

[tex]m = \frac{-3}{1}[/tex]

[tex]m = -3[/tex]

Also; from the question, we understand that the line segment is perpendicular to the above points.

This slope (m2) of the line segment is calculated as:

[tex]m_2 = -\frac{1}{m}[/tex]

Substitute -3 for m

[tex]m_2 = -\frac{1}{-3}[/tex]

[tex]m_2 = \frac{1}{3}[/tex]

Lastly, we calculate the equation of the line using:

[tex]y - y_1 = m_2(x - x_1)[/tex]

The line segment has a midpoint at (3, 1)

So:

[tex]y - 1 = \frac{1}{3}(x - 3)[/tex]

Open bracket

[tex]y - 1 = \frac{1}{3}x - 1[/tex]

Add 1 to both sides

[tex]y - 1 +1= \frac{1}{3}x - 1+1[/tex]

[tex]y = \frac{1}{3}x[/tex]

Hence, the equation of the line segment is: [tex]y = \frac{1}{3}x[/tex]

Answer:

BH = 16

Step-by-step explanation:

The centroid theorem states that the centroid of a triangle is 2/3 of the distance from a vertex to the midpoint of the opposite side.

That means that BH is 2/3 of the length BF.

BH = (2/3)(BF)

BH = (2/3)(24)

BH = 16

Answer:

8 months

Step-by-step explanation:

Given that:

Amount of money present in the bank account = $2,571.68

Automatic monthly rental payments for car loan = $321.46

Any deposits in the bank account are stopped.

To find:

The number of months taken so that the automatic payments make the value of the account as zero?

Solution:

Let the number of months taken to make the value of the account zero = [tex]m[/tex] months

To find the value of [tex]m[/tex], we need to divide the total amount initially present in bank account with the monthly rental payment amount.

Therefore, the equation to find the value of [tex]m[/tex], can be written as:

[tex]m = \dfrac{2571.68}{321.46}[/tex]

On solving the above equation, we get the value as following:

[tex]\bold{m=8}[/tex] months

For number 2 do the same thing as number 1
