Put the following lengths in ascending order, 900cm, 8.9m, 895cm, 9.1m, 12000mm, 0.0092km.
Answer: 8.9 m, 895 cm, 900 cm, 9.1 m, 0.0092 km, 12000 mm
===========================================================
Explanation:
To be able to compare these various measurements, all of them must be the same unit. Let's convert each measurement to meters. If the measurement is already in meters, then we'll move onto the next measurement.
Here are some useful conversion factors
1 m = 100 cm1 m = 1000 mm1 km = 1000 mWith those conversion factors in mind, we get the following conversions:
900 cm = (900 cm)*(1 m/100 cm) = (900/100) m = 9 m8.9 m = already in meters, moving on895 cm = 8.95 meters; divide by 100 to convert from cm to meters as shown above9.1 m = already in meters, moving on12000 mm = (12000 mm)*(1 m/1000 mm) = (12000/1000) m = 12 m0.0092 km = (0.0092 km)*(1000 m/1 km) = (0.0092*1000) m = 9.2 mHere is the summary of the conversions:
900 cm = 9 m8.9 m = 8.9 m895 cm = 8.95 m9.1 m = 9.1 m12000 mm = 12 m0.0092 km = 9.2 mThe original list of
{900cm, 8.9m, 895cm, 9.1m, 12000mm, 0.0092km}
becomes this equivalent list
{9 m, 8.9 m, 8.95 m, 9.1 m, 12 m, 9.2 m}
in that exact order.
After converting everything to meters, we can then sort the values from smallest to largest. Doing so gets us this sorted list of
{8.9 m, 8.95 m, 9 m, 9.1 m, 9.2 m, 12 m}
Then you convert back each measurement to its original form
{8.9 m, 895 cm, 900 cm, 9.1 m, 0.0092 km, 12000 mm}
which is the final answer.

I need help graphing -8x-y=8
Answer:
y = -8x - 8
Step-by-step explanation:
Add -8x on both sides to get -y = 8x + 8 and flip the y sign on the left to get your slope function which is y = - 8x - 8.
To graph the function, you would need to put (0, -8) as your y-intercept, and each unit will go down 8 units when you add 1.
Answer:
y=8x+8
Step-by-step explanation:
Just rewrite the problem so it's in y=mx+b format then it's easy to graph
Remember the y intercept is 8 because when x=0 y=8 and the slope is 8 so go up 8 and right 1

Step-by-step explanation:
From the equation y−3=−2(x+1), identify the slope and a point on the line.
Answer:
slope = - 2, point on line = (- 1, 3 )
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 3 = - 2(x + 1) ← is in point- slope form
with slope m = - 2 and (a, b ) = (- 1, 3 )
The slope of equation y−3=−2(x+1) is -2.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
y−3=−2(x+1)
Using Slope- Intercept form
y= mx + b
So, the slope for the equation is -2.
Hence, the slope is -2.

Megan Dunstall wants to know how many months it would take for $15,000 to earn $618.75 at 51/2% of simple interest?
Answer: 9 months.
Step-by-step explanation:
Simple interest = Principal x rate(in decimal) x Time(in years)
Given: Principal = $15,000 , rate = [tex]5\dfrac12\%=\dfrac{11}{2}\%= 5.5\%= 0.055[/tex]
Interest = $618.75
let t= time
Then,
[tex]618.75=15000\times 0.055\times t\\\\\Rightarrow\ t=\dfrac{618.75}{15000\times0.055}\\\\\Rightarrow\ t= 0.75\ or\ t=\dfrac34\ year[/tex]

Answer:
62°
Step-by-step explanation:
The measure of the external angle where the secants meet is half the difference of the arcs they subtend.
∠A = (DE - BC)/2
2×∠A = DE -BC
DE = BC + 2×∠A
DE = 38° +2(12°)
arc DE = 62°
6(x-4)-x=6x+4 one solution, no solution or infinite solution
Answer:
no solution
Step-by-step explanation:
Given
6(x - 4) = 6x + 4 ← distribute left side
6x - 24 = 6x + 4 ( add 24 to both sides )
6x = 6x + 28 ( subtract 6x from both sides )
0 = 28 ← not possible
This indicates the equation has no solution

How many solutions exist for the given equation?
} (x + 12) = 4x – 1
zero
one
two
infinitely many
Answer:
The given equation has one solution.
Step-by-step explanation:
Given equation is:
(x+12) = 4x-1
We will solve the equation to check how many solutions it has.
x+12 = 4x-1
Adding 1 on both sides
x+12+1 = 4x-1+1
x+13 = 4x
Subtracting x from both sides
x-x+13=4x-x
13 = 3x
x = 13/3
Hence,
The given equation has one solution.

The statement that best explains the relationship between lines FG and HJ is "They are not perpendicular because their slopes are not negative reciprocals."
What is a slope?The slope or gradient of a line in mathematics is a numerical representation of the steepness and direction of the line.
If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,
then the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)
To find the slope;
m = (y₂- y₁) / (x₂ - x₁)
To find the slope of a line passing through two given points, we use the formula:
slope = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are the coordinates of the two points.
For line FG, the two points are F(-4, 1) and G(0, -2):
slope of FG = (-2 - 1) / (0 - (-4)) = (-2 - 1) / 4 = -3/4
For line HJ, the two points are H(-4, -2) and J(0, 4):
slope of HJ = (4 - (-2)) / (0 - (-4)) = 6/4 = 3/2
The slopes of lines FG and HJ are not equal. However, we can see that they are not negative reciprocals of each other:
slope of FG = -3/4
slope of HJ = 3/2
Therefore, lines FG and HJ are not perpendicular because their slopes are not negative reciprocals of each other.

remaining amount.
a) What does commission mean?
b) If a house sells for $345 000, how
much commission does the real estate
agent make on the sale of the house?
Answer:
Commision may be defined as a percentage cut which an employee, broker, vendor, retailer or other persons within a sale chain receive from an employer or production firm for selling a good or offering a successful service based on agreed terms by both parties. ;

Given :
Commision pattern :
5% on first $200,000
6% on remaining amount
Amount of commission on $345000
0.05 * 200000 = 10,000
0.06 * (345000 - 200000) = 8700
Total commission :

The expression that represents Cindy's profit is $3.5b - $128.09.
Cindy's total profit is $30.82.
What is profit?Profit is total revenue less total cost. Total revenue is the selling price per unit multiplied by the total units sold.
Profit = total revenue - total cost
($3.50b) - ($65.25 + $62.84)
$3.5b - $128.09
What is Cindy's total profit?Profit for the first day = $3.5(24 + 15) - $128.09
= ($3.5 x 39) - $128.09
= $136.50 - $128.09
=$8.41
Profit for the next day = $3.5(26 + 17) - $128.09
= ($3.5 x 43) - $128.09
