Answer:
k = 0.25t^2
Step-by-step explanation:
Given the equation :
b = 0.25t
b = number of inches that has burned away
t = time
From our knowledge of variation;
Since candle length will decrease with time ;
b α 1/ t
b = k/t
Where k is the proportionality constant
Comparing the equation :
b = 0.25t
k/t = 0.25t
k = 0.25t^2

find the ratio of 5m to 11m in simple ways
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:
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
Two trains have to travel 300 miles. Train A travels at 50 mph and train B travels at 60 mph. However, Train B leaves 1 hour later. When will the two trains meet?
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

the math teacher gives each student a map of the amusement park that use a coordinate plane the meeting locates is at(0,0) on the map each unit is 100 ft the first ride that you want to try is located at the coordinates (0,4) the next one is located at (3,0) if you walk in a straight line from the first ride to the second ride how many feet would you travel
A.300 feet
B.400feet
C.500feet
D.700feet
Given:
Starting point = (0,0)
First ride = (0,4)
Second ride = (3,0)
In map, each unit = 100 ft
To find:
The actual distance between first and second ride.
Solution:
Distance formula: Distance between two points is
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using the distance formula, we get the distance between first ride and second ride in the map is
[tex]d=\sqrt{(3-0)^2+(0-4)^2}[/tex]
[tex]d=\sqrt{9+16}[/tex]
[tex]d=\sqrt{25}[/tex]
[tex]d=5[/tex]
So, the distance between first ride and second ride in the map is 5 units.
We have,
1 units = 100 ft
5 units = 500 ft
The actual distance between first and second ride is 500 ft.
Therefore, the correct option is C.

The slope of the line is 4 and the y-intercept of the line is -5.
What is an equation of the line?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.

A. tan 272° < 0
B. sin 272° > 0
C. cos 272° < 0
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

What is the equation, in slope-intercept form, of the perpendicular bisector of the given line segment?
y = One-thirdx
y = One-thirdx – 2
y = 3x
y = 3x − 8
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]

A triangle has three vertices located at A(-1, 2), B(-1, 5), and C(-4, 2). List the ordered pairs of the triangle after it has been translated four units to the right, reflected over the x-axis, and then rotated 90oclockwise about the origin.
Answer:
A’ is (-2,-3)
B’ is (-5,-3)
C’ is (2,0)
Step-by-step explanation:
We have three operations to perform;
a) translate 4 units right
means that we add 4 to the x-coordinate
b) Reflect over x-axis
If we reflect over x-axis;
(x,y) becomes (x,-y)
c) Rotate 90 degrees clockwise
(x,y) becomes (y,-x)
We have the following as the solution;
A( - 1,2)
Add 4 to x-coordinate
(3,2)
Reflect over x-axis
(3,-2)
Rotate 90 degrees clockwise
(-2,-3)
for B (-1,5)

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
Greg has $2,571.68 in his bank account and makes automatic monthly rental payments of $321.46 for a car loan. If he stops making deposits to that account, when would the automatic payments make the value of the account zero? Write the equation using m for months that represents this scenario
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:

Kiersten runs a website that helps people learn programming. Every month, Kiersten receives a subscription fee of \$10$10dollar sign, 10 from each of the subscribers to her website. Last month, the website had 100100100 subscribers. This month, 303030 new members joined the website, and 101010 members cancelled their subscription.
How much money will Kiersten’s online business earn this month?
\$
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
