The rental charge, denoted as "y," is determined based on the duration of time, denoted as "x," for which the item or service is rented. Factors such as costs, demand, competition, and desired profit margins influence the specific pricing structure.
The rental charge, denoted as "y," is determined based on the amount of time, denoted as "x," that the item or service is rented for. The longer the duration of rental, the higher the rental charge tends to be. The specific pricing structure for rental charges varies depending on the industry, location, and specific rental service being provided.
Rental charges are typically set by the rental company or service provider and can be influenced by several factors. These factors may include the cost of acquiring and maintaining the rental item, overhead expenses such as storage or transportation costs, demand and market conditions, competition, and desired profit margins.
For example, in the context of car rentals, the rental charge may be based on a fixed rate per hour or may involve different rates for specific time increments (e.g., hourly, daily, weekly). Additionally, there may be additional fees or surcharges based on factors such as mileage, fuel usage, insurance coverage, or any optional extras chosen by the customer.
It's important to note that rental charges can vary significantly across different industries and types of rental services. For instance, the rental charges for equipment rentals, housing rentals, or event space rentals may have different pricing structures and factors influencing the overall cost.
Ultimately, the rental charge is determined by considering various factors that contribute to the cost of providing the rental service and the duration of time for which the item or service is rented.

Decrease 100kg by 30%
Answer:
70
Step-by-step explanation:
the 30/100 of 100 is 30

A mortgage payment is typically made up of four components: principal, interest, taxes, and insurance. The Principal portion is the amount that pays down your outstanding loan amount. Interest is the cost of borrowing money. The amount of interest you pay is determined by your interest rate and your loan balance.
The term “loan” can be used to describe any financial transaction where one party receives a lump sum and agrees to pay the money back. A mortgage is a type of loan that's used to finance a property. A mortgage is a type of loan, but not all loans are mortgages. Mortgages are “secured” loans.

a) A What is the growth factor as a decimal?
b) Estimate the number of students enrolled 10 years from now. Round to the nearest student.
Show your work!!
The growth factor as a decimal is 1.026 and the number of students enrolled 10 years from now is 1939
How to determine the growth factor?The given parameters are
Initial value of enrollment, a = 1500
Rate, r = 2.6%
The growth factor is then calculated as:
Growth factor = 1 + Rate
This gives
Growth factor = 1 + 2.6%
Evaluate the sum
Growth factor = 1.026
Hence, the growth factor as a decimal is 1.026
The number of students enrolled 10 years from nowAs a general rule, the number of students enrolled t years from now is
Students = Initial value * Growth factor^Number of years
This is represented as
Students = 1500(1.026)^t
10 years from now means t = 10
So, we have
Students = 1500(1.026)^10
Evaluate
Students = 1939
Hence, the number of students enrolled 10 years from now is 1939

The volume of the oceans on Earth is approximately 1,386 million km^3. As the Earth's temperature rises, the ice in the polar icecaps melts into the oceans, increasing the volume of the oceans. If 1 cm^3 of ice melts, it turns into approximately 0.92 cm^3 water.
1) There are approximately 3,800 cm^3 in a gallon. If 1.9 m^3 of ice melts, how many gallons of water does this produce? (Round your answer to the nearest gallon.)
2) Scientists estimated that the addition of 1,000 km^3 of water would increase sea levels by 364 cm. Greenland's ice sheet is especially vulnerable to melting. Recent reports indicate a melting average of 195 km^3 of ice per year from Greenland, resulting in additional yearly 179.4 km^3 of water. If melting continues at this rate, how many centimeters would the sea increase after 6 years? (Round your answer to the nearest centimeter.)
Answer:
460 gallons392 cmStep-by-step explanation:
The necessary units conversion can be accomplished by multiplying by appropriate conversion factors. Quantity can be found by multiplying rate by time.
1)The number of gallons of water produced by melting 1.9 m³ of ice is ...
[tex]1.9\text{ m$^3$ (ice)}\times\left(\dfrac{100\text{ cm}}{1\text{ m}}\right)^3\times\dfrac{0.92\text{ cm$^3$ (water)}}{1\text{ cm$^3$ (ice)}}\times\dfrac{1\text{ gal}}{3800\text{ cm$^3$}}\\\\=\dfrac{1.9\times10^6\times0.92}{3800}\text{ gal}=\boxed{460\text{ gal}}[/tex]
2)Multiplying the melting rate by time and converting to height, we have ...
[tex]\dfrac{179.4\text{ km$^3$}}{1\text{ yr}}\times\dfrac{364\text{ cm}}{1000\text{ km$^3$}}\times6\text{ yr}\approx\boxed{392\text{ cm}}[/tex]

Convert 366 minutes to hours.
Knowing that in 60 minutes = 1 hour.[tex]\boldsymbol{\sf{Therefore \ \to \ 366 \not{m}*\dfrac{1 \ hr}{60\not{m}}=6.1 \ hr }}[/tex]

Answer:
the following 3 equations are equivalent :
• x + 1 = 4
• 2 + x = 5
• -5 + x = -2
Step-by-step explanation:
2 + x = 5
x + 1 = 4
9 + x = 6
x + (- 4) = 7
-5 + x = - 2
Let’s take this equation :
x + 1 = 4
=======
By Adding 1 to both sides of the equation we get :
x + 1 + 1 = 4 + 1
⇔ x + 2 = 5
⇔ 2 + x = 5
Then the equations x + 1 = 4 and 2 + x = 5 are equivalent.
…………………………………………………………………
On the other hand ,if we subtract 6 from both sides
of the equation x + 1 = 4 we get :
x + 1 - 6 = 4 - 6
⇔ x - 5 = -2
⇔ -5 + x = -2
Then the equations x + 1 = 4 and -5 + x = -2 are equivalent.
Answer:
A. 2 + x = 5
B. x + 1 = 4
E. -5 + x = -2

If the parabola of equation y=k−x2 is tangent to the line of the equation y=x then what is the value of k ?
The value of k is 1/4.
According to the statement
we have given
The equation of parabola is y=k−x2
And tangent to the line of equation is y = x
and we have to find the value of K.
So, let y=k−x2 -(1)
and let y = x -(2)
(2) is the tangent to the (1) then
therefore they cut at
y=k−x2 -(1)
y = x -(2)
so, put (2) in the (1) then
x = k- (x)^2
(x)^2 + x = k
The above written equation has one real number then for this D =0
so, (x)^2 + x - k = 0
