The equation to find the amount the rental car company will charge for any number of days is y = 75+20(n-3).

Mathematically, an equation can be defined as a statement that supports the equality of two expressions, which are connected by the equals sign “=”.

Given that,

The charge per day for a 3-day rental = 75/3 = 25

The additional charge for an extra 4 days is (155-75)= 80 which is $20 per day.  

The charge for a period of n days (n>3) is then 75+20(n-3).

Thus, The equation to find the amount the rental car company will charge for any number of days is y = 75+20(n-3).

The simple interest rate that you are charged, based on the loan amount and the period of the loan, is 3. 5 %

Borrowers must pay lenders simple interest as a fee in exchange for a loan. Compound interest is excluded from the calculation and just the original principal is used. Simple interest applies to all loans, not just specific ones. Additionally, it refers to the kind of interest that banks give their customers on their savings accounts.

Simple interest is the amount of interest charged on a specific principal amount at a specific interest rate. Compound interest, on the other hand, is the interest that is computed using both the principal and the interest that has accumulated over the preceding period.

To find the simple interest rate, find the simple interest charged per year to be:

= 175 / 2

= $ 87. 50

Then , the simple interest rate would be:

= Simple interest per year / Loan amount

= 87. 50 / 2, 500

= 3. 5 %

Answer:

There were 3 children in the room

Step-by-step explanation:

Let x be the number of children in the room

Since each child has 10 fingers including their thumbs, total number of fingers =10x

Each child has 2 ears so total number of ears = 2x

Since they had 24 more fingers than ears we get the equation:
10x - 2x = 24

8x = 24

x = 24/8 = 3

The larger of the two consecutive even perfect squares is $15,536$.

Square is a four-sided shape that has four equal sides and four right angles. It is the most basic of all quadrilaterals and is a two-dimensional shape. A square has a line of symmetry that passes through the center and divides it into two equal halves. All four sides of a square are equal in length and all four angles are equal to 90 degrees.

To find this, we need to use the difference between the two squares and solve for the larger number. We know that the difference between the two squares is $268$, so we can write the following equation:

$15,536 - 268 = 15,268$

This equation tells us that the larger of the two squares is $15,536$.

O Statistic as it represents the sample

The number 2.5 is considered a statistic because it is calculated from a sample of second graders in a school district. This number is an estimate of the average number of pets that all second graders in the school district have, but it is not the exact number, as the sample may not be fully representative of the population. A parameter, in contrast, is a fixed value that represents a characteristic of a population, such as the population mean or population proportion. Since the number 2.5 is an estimate calculated from a sample and not the exact value of the population, it is considered a statistic.

Giselle worked 12 hours as a carpenter

She also worked 18 hours as a blacksmith

Giselle worked as both a carpenter and a blacksmith

She earned $20 per hour working as a carpenter

She also earned $25 per hour working as a blacksmith

She worked for 30 hours to earn $690

Let x represent the number of hours that she worked as a carpenter

Let y represent the number of hours that she worked as a blacksmith

x + y= 30........equation1

20x + 25y= 690......equation 2

From equation 1

x + y= 30

x= 30-y

Substitute 30-y for x in equation 2

20(30-y) + 25y= 690

600-20y+25y= 690

collect the like terms

600+5y=690

5y= 690-600

5y= 90

y= 90/5

y= 18

Substitute 18 for y in equation 1

x+y= 30

x+18= 30

x= 30-18

x= 12

Hence Giselle worked 12 hours as a carpenter and 18 hours as a blacksmith

The probability of flipping four coins is 0.0625

Total coins = 4

The study of chances, which are determined by the ratio of favourable occurrences to probable cases, is known as probability.

Thus, the probability is = 1/2

The number of non-similar 1000-pointed stars is

[tex]$\frac{1000-600-2}{2}= \boxed{199}.$[/tex]

If we join the adjacent vertices of the regular [tex]$n$[/tex]-star, we get a regular [tex]$n$[/tex][tex]-gon[/tex]. We number the vertices of this [tex]$n$[/tex][tex]-gon[/tex] in a counter clockwise direction: [tex]$0, 1, 2, 3, \ldots, n-1.$[/tex]

A regular [tex]$n$[/tex]-star will be formed if we choose a vertex number m where [tex]$0 \le m \le n-1$[/tex], and then form the line segments by joining the following pairs of vertex numbers:[tex]$(0 \mod{n}, m \mod{n}),$ $(m \mod{n}, 2m \mod{n}),$ $(2m \mod{n}, 3m \mod{n}),$ $\dots,$ $((n-2)m \mod{n}, (n-1)m \mod{n}),$ $((n-1)m \mod{n}, 0 \mod{n}).$[/tex]

If [tex]$\gcd(m,n) > 1$[/tex], then the star degenerates into a regular [tex]$\frac{n}{\gcd(m,n)}$-gon[/tex] or a (2-vertex) line segment if [tex]$\frac{n}{\gcd(m,n)}= 2$[/tex]. Therefore, we need to find all $m$ such that [tex]$\gcd(m,n) = 1$.[/tex]

Note that [tex]$n = 1000 = 2^{3}5^{3}.$[/tex]

[tex]Let $S = \{1,2,3,\ldots, 1000\}$, and $A_{i}= \{i \in S \mid i\, \textrm{ divides }\,1000\}$. The number of $m$'s that are not relatively prime to $1000$ is: $\mid A_{2}\cup A_{5}\mid = \mid A_{2}\mid+\mid A_{5}\mid-\mid A_{2}\cap A_{5}\mid$ $= \left\lfloor \frac{1000}{2}\right\rfloor+\left\lfloor \frac{1000}{5}\right\rfloor-\left\lfloor \frac{1000}{2 \cdot 5}\right\rfloor$ $= 500+200-100 = 600.$[/tex]

[tex]Vertex numbers $1$ and $n-1=999$ must be excluded as values for $m$ since otherwise a regular n-gon, instead of an n-star, is formed.[/tex]

The cases of a 1st line segment of (0, m) and (0, n-m) give the same star. Therefore we should halve the count to get non-similar stars.

Therefore, the number of non-similar 1000-pointed stars is

[tex]$\frac{1000-600-2}{2}= \boxed{199}.$[/tex]

[tex]Note that in general, the number of $n$-pointed stars is given by $\frac{\phi(n)}{2} - 1$ (dividing by $2$ to remove the reflectional symmetry, subtracting $1$ to get rid of the $1$-step case), where $\phi(n)$ is the Euler's totient function.[/tex] [tex]It is well-known that $\phi(n) = n\left(1-\frac{1}{p_1}\right)\left(1-\frac{1}{p_2}\right)\cdots \left(1-\frac{1}{p_n}\right)$, where $p_1,\,p_2,\ldots,\,p_n$ are the distinct prime factors of $n$.[/tex] [tex]Thus $\phi(1000) = 1000\left(1 - \frac 12\right)\left(1 - \frac 15\right) = 400$, and the answer is $\frac{400}{2} - 1 = 199$.[/tex]

Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent.

If the respective sides of two triangles have the same ratio and the corresponding angles are equal, then the triangles are comparable (or proportion). Triangles that are similar will have the same form but may not be the exact same size.

Two triangles are said to be similar if their corresponding angles are equal. Equiangular triangles are what they are called. Two equiangular triangles were the subject of a significant finding made by the well-known Greek mathematician Thales.
