The rate at which Riya is applying the mulch to the garden is 250000:1.
What is the rate?It should be noted that rate is simply used to show the relationship between two things. A rate in mathematics is the comparison of two related values expressed in different units. The numerator of the ratio expresses the corresponding rate of change in the dependent variable if the denominator of the ratio is written as a single unit of one of these quantities and it is assumed that this quantity may be modified systematically (i.e., is an independent variable).
Per unit of time is a frequent sort of rate, and examples include speed, heart rate, and flux. Exchange rates, literacy rates, and electric field ratios are examples of ratios with a non-time denominator (in volts per meter).
From the information, Riya is applying mulch to the garden and she applied at a rate of 250000cm³ for every m² of space.
Therefore, the rate at which Riya is applying the mulch to the garden is 250000:1.

ABC is a right triangle with vertices at A (0,0), B (0, 2b) and C (2a, 0). Point D (a, b) is the
midpoint of BC. Which of the following statements could be used to show that the midpoint of the hypotenuse of any right triangle is equidistant from the vertices of the triangle?
Using the midpoint concept and the distance between two points, the correct statement is given by:
[tex]\sqrt{(0 - a)^2 + (2b - b)^2} = \sqrt{(2a - a)^2 + (0 - b)^2} = \sqrt{(a - 0)^2 + (b - 0)^2}[/tex]
What is the midpoint concept?The midpoint between two points is the halfway point between them, and is found using the mean of the coordinates.
Hence the coordinates of the midpoint of the hypotenuse are given as follows:
x: (2a + 0)/2 = a.y: (0 + 2b)/2 = b.What is the distance between two points?Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:

Can (x↑y)2/3 be simplified? yes or no
If yes show how with work if not explain why
Note show your work or ill delete your answer.
It depends on what you mean "simplify". Chances are the goal here is to resolve any exponents that are improper fractions, meaning we don't want exponents larger than 1, like 4/3, for instance, but smaller than 1, like 2/3, is okay.
Now, by the distributive property of exponentiation,
[tex]\left(x^4 y\right)^{2/3} = \left(x^4\right)^{2/3} y^{2/3}[/tex]
Since [tex](x^a)^b = x^{ab}[/tex], we have
[tex]\left(x^4 y\right)^{2/3} = x^{4\cdot2/3} y^{2/3} = x^{8/3} y^{2/3}[/tex]
Convert the improper fraction to a mixed number.
[tex]\dfrac83 = 3 + \dfrac23[/tex]
Then we can write
[tex]x^{8/3} = x^{3 + 2/3} = x^3 x^{2/3}[/tex]
since [tex]x^{a+b}=x^ax^b[/tex].
Finally, we group together the factors with the same power.
[tex]\left(x^4 y\right)^{2/3} = x^3 x^{2/3} y^{2/3} = \boxed{x^3 (xy)^{2/3}}[/tex]
Find an equation of the line passing through the points (5, 2) with the slope m =5/6
Step-by-step explanation:
I guess, the equation is meant to be in slope-intercept form :
y = ax + b
"a" is the slope, "b" is the y intercept (the y value when x = 0).
in a situation like this, where we have the slope and one point of the line, we can start with the point-slope form
y - y1 = a(x - x1)
"a" is again the slope, and (x1, y1) is the given point.
and then we transform this over to the slope-intercept form.
so, in our case here
y - 2 = 5/6 × (x - 5) = 5x/6 - 25/6
let's simplify this by multiplying everything by 6 :
6y - 12 = 5x - 25
6y = 5x - 13
y = 5/6 x - 13/6
or
y = 1/6 × (5x - 13)
PLEASE HELPP!!! 7(5h - 4) - 1 = 14 - 8h Show your work!!!!
Answer: h=1
Step-by-step explanation:
multiple 5h and -4 by 7
35h-28-1=14-8h
35h-29=14-8h
add 29 to both sides
35h=43-8h
43h=43
i think this is right...
The given equation is,
→ 7(5h - 4) - 1 = 14 - 8h
Now the required value of h will be,
→ 7(5h - 4) - 1 = 14 - 8h
→ 35h - 28 - 1 = 14 - 8h
→ 35h - 29 = 14 - 8h
→ 35h + 8h = 14 + 29
→ 43h = 43
→ h = 43/43
→ [ h = 1 ]
Hence, the value of h is 1.

D.
A number line ranges from 0 through 10 from left to the right in increments of 1. A hollow circular point is at 6. An arrow extends from the point toward the right.
Answer:
D.
Step-by-step explanation:
Hey there!
In order to find which description of the graph matches the problem, we must first create an equation or an inequality
So, we need to find how much more people the company needs to reach their goal to generate at least $7,300 in monthly revenue
We know that each person adds $300 to the already total of $5,500 per month
Now we can form the equation with this knowledge
[tex]300x + 5,500 \geq 7,300[/tex] where x is the number of people
Now we can simplify the equation
[tex]300x\geq 7500 - 5500\\ 300x\geq 2000\\x\geq 6.67[/tex]
Since we cannot have 6.67th of a person, we must round down because it means that we need more than 6 people
If we round up, it means that you need more 7 people in order to get $7,300 which isn't true
This means, you need more than 6 salespeople per month in order to meet the monthly quota of $7,300 in monthly revenue
Now that we know this, we can make a graph, or find the correct description of the graph
Since they need more than 6 people, the dot that sits on 6 in the number line will not be filled in, indicating that you need more than 6 salespeople
And since we need MORE, not LESS, the line will be pointing to the right
So, the correct answer would be D.

50 points!! Find the two consecutive asymptotes, the period (in radians), the phase shift (in radians) and the vertical shift of the function: y = 4csc(5θ - 3π/4)
Two consecutive asymptotes are θ = - π / 20 and θ = 3π / 20 and the period is π / 5.
How to determine two consecutive asymptotes from a trigonometric function
In this question we must look for two consecutive vertical asymptotes related to a trigonometric function. A function becomes undefined when its denominator is zero. Now we proceed to simplify the expression by trigonometric formulas:
y = 4 · csc (5θ - 3π / 4)
y = 4 / sin (5θ - 3π / 4)
y = 4 / (sin 5θ · cos 3π / 4 - cos 5θ · sin 3π / 4)
y = 4 / [(- √2 / 2) · sin 5θ - (√2 / 2) · cos 5θ]
The function is undefined for (- √2 / 2) · sin 5θ - (√2 / 2) · cos 5θ = 0:
(- √2 / 2) · sin 5θ - (√2 / 2) · cos 5θ = 0
(- √2 / 2) · sin 5θ = (√2 / 2) · cos 5θ
- sin 5θ = cos 5θ
tan 5θ = - 1
5θ = - π / 4 + i · π
θ = - π / 20 + i · π / 5
θ = (π / 5) · (- 1 / 4 + i)
There are two consecutive asymptotes:
i = 0
θ = - π / 20
i = 1
θ = 3π / 20
And the period is ΔT = 3π / 20 - (- π / 20) = π / 5.

A florist buys a dozen roses for $12.96 and sells them for $48.48. Find the amount of markup on a single rose.
The amount of markup on a single rose is $2.74.
What is markup formula?The markup formula is defined as the profit per unit cost of an item and is given as,
Markup = 100 * profit/cost
We multiply by 100 because we express it as a percentage, not as a fraction.
Now it is given that,
Cost Price of a dozen roses = $2.96
Number of roses = 12
Thus, Cost Price of 1 rose = 12.96/12 = $.108
Now it is also given that, the these dozen roses are sold at $48.48
So, Selling price of 1 rose = 48.48/12 = $4.04
Thus, Profit = Selling Price - Cost Price
⇒ Profit = $4.04 - $1.08
⇒ Profit = $2.96
Thus,Amount of Markup of single rose = Profit/Cost of 1 rose
⇒ Amount of Markup of single rose = 2.96/1.08
⇒ Amount of Markup of single rose = 2.74
Thus, the amount of markup on a single rose is $2.74.

If you need to drive 30 miles, you have many options. For instance, you can drive 15 miles per hour for 2 hours, 30 miles per hour for 1 hour, or 60 miles per hour for half an hour. Notice that when you double your speed, it takes half as much time to get to your destination. Mathematicians describe this kind of relationship as an inverse variation. Why do you suppose they use the word inverse to describe it?
The word Inverse is used here because as the speed of traveled goes on increase, then the amount of time it takes to travel a particular distance will decrease .
What is inverse variation ?The inverse variation property states that , whenever the product of values of two quantities is a constant value then there is opposite variation between these two corresponding values. Or we can also say that if the productive nature of two corresponding values is constant, then one quantity is inversely varies with second quantity.

Find the inverse of each function. Determine whether each inverse is a function. f(x)=(2 x-3)²
The inverse of function f( x ) = ( 2x - 3)² is [tex]y=\frac{\pm\sqrt{x} +3}{2}[/tex].
A function that can reverse into another function is known as an inverse function or anti-function. A function takes in values, applies specific operations to them, and produces an output. In order to find y when x is swapped with another variable, we must first determine the inverse function. On the other hand, the inverse function and the original function likewise have interchangeable domains and ranges.
We have the function,
f(x) = y = ( 2x - 3 )²
x = ( 2y - 3 )²
2y - 3 = ±√x
Adding 3 from each side.
2y - 3 + 3 = ±√x + 3
2y = ±√x + 3
Dividing each side of the equation by 2.
[tex]y=\frac{\pm\sqrt{x} +3}{2}[/tex]
Hence, the inverse of function f( x ) = ( 2x - 3 )² is [tex]y=\frac{\pm\sqrt{x} +3}{2}[/tex].
