Answer:
option A) New cars and used cars is correct option.
Step-by-step explanation:
loan Interest rate can be defined as the percentage of a loan paid by borrowers to lenders. For most loans, interest is paid in addition to principal repayment in order to compound over time.
since new cars have more price than old cars that's why new cars have more greater loan interest than old cars
hence option a is correct
There is generally a significant difference in loan interest rates between new cars and used cars, with new cars usually having lower rates. Institutions regard new cars as less risky than used or refinanced cars, hence, they tend to offer lower interest rates to encourage new car loans.
Explanation:There is typically a significant difference in loan interest rates between new cars and used cars. This is mainly because new cars tend to have lower interest rates than used cars. Financial institutions, such as banks and credit unions, usually perceive new cars as less risky because they have not been subjected to any wear and tear compared to used cars which could potentially have mechanical issues. Consequently, these institutions lower the interest rates for new car loans to encourage more borrowers.
Whereas, in the case of used cars and refinanced cars, the interest rates are significantly higher due to the increased risk that the lender has to take on.

A spherical scoop of ice cream with a diameter of 8 cm rests on top of a sugar cone that is 12 cm deep and has a diameter of 8 cm. What percent of the ice cream must be eaten to insure it does not overflow the cone when it melts?
Answer: 25% of the ice cream must be eaten to insure it does not overflow the cone when it melts.
Step-by-step explanation:
1. You must calculate the area of spherical scoop of ice cream with the following formula for calculate the volume of a sphere:
[tex]Vs=\frac{4}{3}r^{3}\pi[/tex]
Where [tex]r[/tex] is the radius ([tex]r=\frac{8cm}{2}=4cm[/tex])
[tex]Vs=\frac{4}{3}(4cm)^{3}\pi=268.08cm^{3}[/tex]
2. Now, you need to calculate the volume of the sugar cone with the following formula:
[tex]Vc=\frac{1}{3}r^{2}h\pi[/tex]
Where [tex]r[/tex] is the radius ([tex]r=\frac{8cm}{2}=4cm[/tex]) and [tex]h[/tex] is the height ([tex]h=12cm[/tex]):
[tex]Vc=\frac{1}{3}(4cm)^{2}(12cm)\pi=201.06cm^{3}[/tex]
3. When the ice cream melt, the percent of the cone that will be filled is:
[tex]P_f=(\frac{201.06cm^{3}}{268.08cm^{3}})100=75[/tex]%
4. Therefore, the percent of the ice cream that must be eaten to insure it does not overflow the cone when it melts, is:
[tex]P_e=100[/tex]%[tex]-75[/tex]%
[tex]P_e=25[/tex]%
Final answer:
To ensure the melted ice cream does not overflow the cone, 75% of the ice cream must be eaten. This is calculated by finding the volumes of the ice cream sphere and the cone and comparing them to get the percentage that can fit into the cone without overflowing.
Explanation:
The student's question involves determining what percent of a spherical scoop of ice cream (with a diameter of 8 cm) must be eaten to ensure it does not overflow a sugar cone (also with a diameter of 8 cm and 12 cm deep) when the ice cream melts. The ice cream and the cone have the same diameter, so they have the same base area. To prevent overflow, the volume of the melted ice cream must be less than or equal to the volume of the cone.
To solve this, we must first calculate the volume of the spherical scoop of ice cream, which can be determined using the formula for the volume of a sphere: V = (4/3)πr³. Subsequently, we need to calculate the volume of the cone using the formula for the volume of a cone: V = (1/3)πr²h. We shall compare these volumes to find out the percentage of ice cream that must be eaten.
Let's calculate the volume of the sphere (ice cream):
V_s = (4/3)π(4 cm)³ = (4/3)π(64 cm³) = 256π/3 cm³
Now let's calculate the volume of the cone:
V_c = (1/3)π(4 cm)²(12 cm) = (1/3)π(16 cm²)(12 cm) = 64π cm³
To prevent overflow, the volume of melted ice cream should be the same or less than the volume of the cone. Therefore, the portion which would fit into the cone without overflowing when melted is:
percent = (V_c / V_s) × 100 = (64π / 256π/3) × 100 = 75%
This means that 75% of the ice cream must be eaten to ensure it does not overflow the cone when it melts.

In a recent election the new mayor received three votes for every vote received by her opponent. The new mayor received 2058 votes. How many votes did her opponent receive?
As per the given values, the opponent received 686 votes.
Explanation:Total votes received by Mayor = 2058.
To find out how many votes the opponent received, we need to determine the ratio of votes received between the new mayor and her opponent. Given that the new mayor received three votes for every vote received by her opponent, we can set up the equation:
3x = 2058
where x represents the number of votes received by the opponent. To solve for x, we divide both sides of the equation by 3:
x = 2058 ÷ 3
= 686
Therefore, the opponent received a total of 686 votes.

The Ebbinghaus model of human memory may be used to model the amount of acquired knowledge a college student will retain after “cramming” for a final exam. The formula is p=(100-a)e^-b(0.07), where a and b vary from one person to another, and p is the percent of retained knowledge 1/2 day later when the student actually takes the final exam. If a = 20 and b = 1.2 for a typical student, how much of their “crammed” knowledge will that student retain at the moment of taking the final exam?
Answer: 73.55%
Step-by-step explanation:
p = (100-a) e^-b(0.07)
we have a = 20 and b =1.2

Answer:-
[tex]11.4 + 0.5y = 9.9 + 0.6y[/tex] , then the two states have the same population.
Step-by-step explanation:
Let y represents the number of years
As per the statement:
In 2000, Ohio's population was 11.4 million and and increasing by 0.5 million each year.
⇒ [tex]11.4 + 0.5y[/tex]
and
also, it is given that: Michigan's population was 9.9 million, increasing by 0.6 million each year.
⇒ [tex]9.9 + 0.6y[/tex]
When two states have the same population.
then the equation : [tex]11.4 + 0.5y = 9.9 + 0.6y[/tex].
Answer:
In 15 years the population will be same.
Step-by-step explanation:
Let y represent the number of years.
In 2000, Ohio's population was 11.4 million and and increasing by 0.5 million each year.
[tex]x=11.4+0.5y[/tex]
Michigan's population was 9.9 million, increasing by 0.6 million each year.
[tex]x=9.9+0.6y[/tex]
We have to tell that when will the two years have the same population, so we will put both equations equal.
[tex]11.4+0.5y=9.9+0.6y[/tex]
=> [tex]11.4-9.9=0.6y-0.5y[/tex]
=> [tex]0.1y=1.5[/tex]
So, y = 15
Therefore, in 15 years the population will be same.

A rocking horse has a weight limit of 60 pounds .What weight is 95 percent of the limit?
Answer:
57 pounds weight is 95 percent of the limit .
Step-by-step explanation:
Formula
[tex]Percentage = \frac{Part\ value\times 100}{Total\ value}[/tex]
As given
A rocking horse has a weight limit of 60 pounds .
Here
Percentage = 95%
Total value = 60 pounds
Put in the formula
[tex]Percentage = \frac{Part\ value\times 100}{Total\ value}[/tex]
[tex]95 = \frac{Part\ value\times 100}{60}[/tex]
[tex]Part value = \frac{95\times 60}{100}[/tex]
[tex]Part value = \frac{5700}{100}[/tex]
Part value = 57 pounds
Therefore 57 pounds weight is 95 percent of the limit .
Answer:
57 pounds is 95 percent of the limit.
Step-by-step explanation:
Given the statement: A rocking horse has a weight limit of 60 pounds.
⇒Weight limit of rocking horse = 60 pounds.
To find what weight is 95 percent of the limit.
Let x be the weight.
then;
x = 95% of 60
[tex]x = \frac{95}{100} \times 60[/tex]
or
x = [tex]\frac{95 \times 60}{100} = \frac{5700}{100} = 57[/tex]
therefore, 57 pounds is 95 percent of the limit.
In ∆PQR, PQ = 39 cm and PN is an altitude. Find PR if QN = 36 cm and RN = 8 cm.
Use the Pythagorean theorem two times:

second time:
[tex]PR^2=RN^2+NP^2\\\\x^2=8^2+15^2\\\\x^2=64+225\\\\x^2=289\to x=\sqrt{289}\\\\\boxed{x=17\ cm}[/tex]
Answer: PR = 17 cm.Answer:
17 cm
Step-by-step explanation:
We must first find the length of the height, PN. Since PN is an altitude, it makes a right angle with QR; this means that PNQ will be a right triangle, as will PNR. This means we will use the Pythagorean theorem:
a²+b² = c²
Letting h represent PR (since it is the height),
h²+36² = 39²
h²+1296 = 1521
Subtract 1296 from each side:
h²+1296-1296 = 1521-1296
h² = 225
Take the square root of each side:
√(h²) = √(225)
h = 15
PN is 15 cm.
Now we will use it and the other "base," RN, to find PR:
15²+8² = x²
225+64 = x²
289 = x²
Take the square root of each side:
√(289) = √(x²)
17 = x

You have 10 numbers to choose from, and you're choosing 4 from that pool. Order of the numbers matters, because having 1234 as a PIN is not the same having it be 1324, so we're counting the number of permutations of 10 digits taken 4 at a time. So there are
[tex]4!\dbinom{10}4=4!C(10,4)=4!C^{10}_4=\dfrac{10!}{(10-4)!}=5040[/tex]
possible PINs that can be made.
Answer:
5,040 PINs
Step-by-step explanation:
From the vast numbers from 1 to 10, the numbers can amount to over 5,040 PINs. Having to use the following equation in the attachment below (also found in the other question), the vast amount of numbers can either amount to 5,040 PINs, or possibly over that amount.
You need to have 10 numbers to choose from.
I hope this helps!
