Answer:
Tax rate is 5.5% because 1,375/25,000 is equal to 0.055 which is 5.5 in percentage form. To prove it you can multiply 25,000 by 0.055 and get 1,375.
Step-by-step explanation:
Sales tax rate is 5.5% of cost of car.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given,
Price of the car = $25000
Tax on car = $1375
Sales tax rate = ($1375/$25000)×100
= 0.055 × 100
= 5.5%
5.5 % of sales tax is applied on the cost of car.

What is the difference between a rational and irrational number?
Answer:
Rational numbers are the numbers which are integers and fractions
Irrational numbers are the numbers whose expression as a fraction is not possible
Examples of Rational Number
1/9 – Both numerator and denominator are integers.
7 – Can be expressed as 7/1, wherein 7 is the quotient of integers 7 and 1.
√16 – As the square root can be simplified to 4, which is the quotient of fraction 4/1
0.5 – Can be written as 5/10 or 1/2 and all terminating decimals are rational.
0.3333333333 – All recurring decimals are rational.
Examples of Irrational Number
√2 – √2 cannot be simplified and so, it is irrational.
√7/5 – The given number is a fraction, but it is not the only criteria to be called as the rational number. Both numerator and denominator need to integers and √7 is not an integer. Hence, the given number is irrational.
3/0 – Fraction with denominator zero, is irrational.
π – As the decimal value of π is never-ending, never-repeating and never shows any pattern. Therefore, the value of pi is not exactly equal to any fraction. The number 22/7 is just and approximation.
0.3131131113 – The decimals are neither terminating nor recurring. So it cannot be expressed as a quotient of a fraction.
At a restaurant, the amount of your bill before taxes and tip is $19.83. A 6% sales tax is applied to your bill, and you leave a tip equal to 19% of the original amount. Use mental math to estimate the total amount of money you pay to the nearest dollar.
Answer:
$24.7875
Step-by-step explanation:
Step one:
given data
your bill before taxes and tip is $19.83
6% sales tax
tip equal to 19% of the original amount.
Required
The total expenses
Step two:
let the total expenses be y
let us calculate the cost of tax and the tip
Tax
=6/100*19.83
=0.06*19.83
=$1.1898
Tip
=19/100*19.83
=0.19*19.83
=$3.7677
Total
Y= 19.83 +1.1898 +3.7677
Y= $24.7875

|-1|=-1 is this true
Answer:
False
Step-by-step explanation:
The question is asking for the absolute value of -1. The absolute value is the distance of a number from 0. Think of a number line. -1 is one place away from 0, so the absolute value of -1 is 1. Therefore, the statement is not true.
why is the graph of the rose curve r=4cos2theta
Answer:
The correct answer is B.
Step-by-step explanation:
Any point can be represented in polar form by using the notation:
[tex]A = (r, \theta)[/tex] (1)
And any polar function must satisfy the following definition:
[tex]r = f(\theta)[/tex]
Let [tex]r(\theta) = 4\cdot \cos 2\theta[/tex], where [tex]r[/tex] is the radial distance of any point of the curve from origin and [tex]\theta[/tex] is the direction of any point of the curve with respect to +x semiaxis, measured in radians.
Finally, we proceed to graph the function with the help of a graphing tool and attach the result.
Besides, we must remember that cosine is a bounded function, which means that domain and range in rectangular coordinates are represented by:
[tex]Dom\{f\} = [-4,4][/tex], [tex]Ran\{f\} = [-4,4][/tex]
Then, the correct answer is B.

For each 13 mm of coloured fabric Gordon uses to make his curtains he also uses 1 cm of white fabric express the amount of white fabric to coloured fabric as a ratio in its simplest form
Answer:
[tex]\frac{10}{13}[/tex]
Step-by-step explanation:
In the question, the units of the length of both colored and white fabrics are not the same. So, convert the unit of the white fabrics into mm.
The length of colored fabric used = 13 mm.
The length of white fabric used = 1 cm
= 10 mm
To express the white fabric to colored fabric, we have;
[tex]\frac{length of white fabric used}{length of colored fabric used}[/tex] = [tex]\frac{10mm}{13mm}[/tex]
= [tex]\frac{10}{13}[/tex]
Thus, the amount of white fabric to colored fabric can be expressed as[tex]\frac{10}{13}[/tex].

a/k + b = c/k make k as a subject
Answer:
By "make k as a subject", I assume you mean to solve for k?
If that is the case, then the answer is:
k = (c - a) / b
Step-by-step explanation:
Let's solve for k
a/k + b = c/k
Multiply both sides by k:
a + bk = c
Group terms containing k on the left:
bk = c - a
Divide both sides by k:
k = (c - a) / b

A perfectly spherical scoop of ice cream has a surface area of 36π cm2 and the same diameter as the open end of the ice cream cone it rests on. The cone is 11 cm tall. If the ice cream melts into the cone, what volume of ice cream will overflow?
Answer:
9.43 cm³
Step-by-step explanation:
Given that the surface area of the spherical scoop is 36π cm², we find its radius. The surface area of a sphere, A = 4πr² where r = radius
36π cm² = 4πr²
r² = 36π cm²/4π
r² = 9 cm²
r = √(9 cm²)
r = 3 cm
So, the volume of the spherical scoop of ice cream is thus V = 4πr³/3
= 4π(3 cm)³/3
= 4π(9 cm³)
= 36π cm³
The volume of the ice cream cone is V' = πr²h/3 where r = radius of cone = radius of spherical scoop = 3cm and h = height of cone = 11 cm
V' = π(3 cm)² × 11 cm/3
= 9π cm² × 11 cm/3
= 33π cm³
So, the volume of ice cream that will overflow is thus V - V' = 36π cm³ - 33π cm³
= 3π cm³
= 9.43 cm³
