The definition of the domain of the function f: {4, 6, 8} ⇒{2, 3} over {(4, 2), (6, 2), (8, 2)} is given as {4,6,8}, while the range is given as 2.
What is function?A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Four main categories can be used to classify different sorts of functions. One to one function, many to one function, onto function, one to one and into function—all based on the element. A relation between a domain and range is called a function when each value in the domain only has one value in the range.
Here,
function f : {4, 6, 8} → {2, 3} is defined as {(4, 2), (6, 2), (8, 2)},
domain={4,6,8}
range={2}
The domain of function f : {4, 6, 8} → {2, 3} is defined as {(4, 2), (6, 2), (8, 2)} will be {4,6,8} and range will be {2}.

A bread is cut into 10 equal parts. How many children can share all parts of the bread if each child takes 0.2 parts

What are Fractions?Fraction are numbers of the form [tex]\frac{a}{b}[/tex] where a and b are real numbers. It is represented as a portion or part of a whole.
The number on the top is called numerator and the number on the bottom is called denominator.
There are 10 equal parts of bread and each child takes 0.2 part.
Total parts of the bread = 10
Part each child takes = 0.2 = [tex]\frac{2}{10}[/tex]
2 parts out of 10 are taken by each child.

The required state income tax owed on a $90,000 per year salary is $4950.
Given that,
A table shows the income tax owed by the state on the particularar salary,
Income Range ($) Tax Rate
0 - 10,000 3%
10,001 - 50,000 5%
50,001 - 100,000 5.5%
The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
on $90,000
Tax owed = 5.5% of 90000, because this salary lies in the segment 50,001 - 100,000.
Tax owed = 0.055[90000] = $4950
Thus, the required state income tax owed on a $90,000 per year salary is $4950.

Rounding to the nearest tenth, we get that the length of KN is approximately 21.8.
What is a Pythagoras theorem?
The theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. This relationship is often expressed in the form of the equation:
a² + b² = c²
To find the length of KN in this right triangle, you can use the Pythagorean theorem. This theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
In this case, the hypotenuse is KL, and the other two sides are KM and KN. The theorem can be written as:
KL² = KM² + KN²
Substituting the given values, we get:
24² = 10² + KN²
Solving for KN, we get:
KN² = 24² - 10²
= 576 - 100
= 476
KN = √476
= 21.84
Hence, rounding to the nearest tenth, we get that the length of KN is approximately 21.8.

Let rrr represent the number of additional rolls that sofia orders. 1) which inequality describes this scenario? choose 1 answer: choose 1 answer:.
In linear equation, Sofia will order 7 more rolls of sushi (84 pieces) and pay $56.
What in mathematics is a linear equation?
A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.
Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.
They need at least 100 pieces of sushi
Sofia had ordered and paid for 24 pieces of sushi already
Sushi comes in rolls
Each roll=12 pieces at $8
R=additional rolls that Sofia orders
Additional sushi= Needed sushi - ordered sushi
=100-24
=76 pieces of sushi
Each roll has 12 pieces
76/12=6.33
Sofia has to order in rolls
So, she will order 7 more rolls of sushi of 12 pieces each
12*7=84 pieces
Recall, that they needed at least 100 pieces, so the number of pieces could be more than 100
If Sofia orders 84 pieces + the already ordered 24 pieces
Total pieces=108 pieces
She has paid for 24 pieces (3 rolls) at $8 per roll
7 rolls=$8*7

A loan of $740 is taken out a daily interest of 0.66%. How much will it cost to pay off the loan after 57 days?
Answer:

Step-by-step explanation:
Interest formula is I = Prt/100
where P = principal
r = interest rate (in percent)
t = number of time periods
Here we have P = 740
interest = 0.66% per day
t = 57 days
I = 740 x 0.66 x 57 /100 = 278.39 (rounded)
Total amount to pay back = 740 + 278.39 = $1,018.39

A laptop computer originally priced at $2100 now ell for $2,200. What i the percent of increae?
The percent of increase is 4.761 %
Given :
A laptop computer originally priced at $2100 now and sell for $2,200.
Percentage :
In mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100.
If we have to calculate percent of a number, divide the number by the whole and multiply by 100.
Difference = sell price - original price
= 2200 - 2100
= 100
Percent of increase = 100 * 100 / 2100
= 100 * 1 / 21
= 100 / 21
= 4.761 %
Therefore 4.761 % increase in percent.

In this question, we have been given that the 6th grade students went on a field trip to see a ballet.
The students filled 702 seats leaving 35% vacant.
We need to find the total seats in the theater.
Let there were n seats in the theater.
Given that 35 percent of total seats were vacant.
So, we get an equation,
702 + (35% of n) = n
702 + 0.35n = n
(1 - 0.35)n = 702

The calculated value of the rocket's greatest height is 196 feet
Calculating the rocket's greatest height?From the question, we have the following parameters that can be used in our computation:
height function, h(t) =-16t² + 80t + 96
So, we have
h(t) =-16t² + 80t + 96
The maximum value of t is calculated as
t = -b/2a
So, we have
t = -80/(2 * -16)
Evaluate
t = 2.5
The rocket's greatest height is at t = 2.5
So, we have
h(2.5) =-16(2.5)² + 80(2.5) + 96
Evaluate
h(2.5) = 196

Since , the number gets divided completely
therefore the estimated quotient and the actual quotient will be 2110.
We first round the dividend and the divisor to the closest tens, hundreds, or thousands, and then divide the rounded figures to approximate the quotient. When the divisor in a division sum has two or more digits, it is helpful to first estimate the quotient before attempting to discover the exact number.
