The points P, Q, R, S, T, U, A and B on the number line are such that, TR = RS = SU and AP = PQ = QB. Name the rational numbers represented by P, Q, R and S.
The rational numbers are represented by P, Q, R, and S is mathematically given as
R= -4/3S= -5/3P= 7/3Q = 8/3This is further explained below.
What are the rational numbers?We make use of the idea of a number line, which displays the actual numbers in ascending order from left to right and from left to right to left.
One unit represents the distance between point U and point T.
It is separated into three sections that are all the same size.
Generally, the equation for TR is mathematically given as
TR = RS = SU
Therefore
TR = RS = SU = 1/3
[tex]R = -1 - (1/3)\\ R= -4/3\\\\S = -1 - (2/3) \\S= -5/3[/tex]
Considering the value of P
[tex]P = 2 + 1/3 = 6/3 + 1/3[/tex]
P= 7/3
Considering the value of Q
[tex]Q = 2 + 2/3 = 6/3 + 2/3[/tex]
Q = 8/3

You deposit $675 in a savings account that earns 6% interest compounded
monthly.
a. Write a function that represents the balance after t years.
b. What is the balance after 3 years?
$ 807.76 is the balance after 3 years by compound interest.
What is compound interest with example?
When you earn interest on both the money you have saved and the interest you have already received, this is known as compound interest.For instance, after a year, if you deposited $1,000 in an account with 1% yearly interest, you would have received $10 in interest. Compound interest allows you to earn 1 percent on $1,010 (principal plus interest), or $10.10 in interest payments for the year, in Year Two.Given
Principal , P = $675
Rate , r = 6% = 0.06
Time = t years
n = 12 (compounded monthly)
(a)
Balance after t years is given as,
A = P(1 + r/n)nt
A = 675(1 + 0.06/12)12t
A = 675(1.005)12t
Balance after t years = 675(1.005)12t
(b)
Balance after 3 years = 675(1.005)12*3
= 675(1.005)36
= 675*1.19668
=807.7593 \approx 807.76

Which of the following statements is true when comparing numbers using a number line?
The number closest to zero is always the least.
The number farthest from zero is always the greatest.
The number farthest right is always the least.
The number left is always the least.
From the given statements, the statement which is true when comparing numbers using a number line is :
The number left is always the least.
The definition of a number line is a straight line that shows numbers arranged at equal distances.
A number line is often shown horizontally and can be extended indefinitely in any direction.
Moving right causes the numbers to increase (or become greatest), while moving left causes the numbers to decrease ( or becomes least).
Larger numerals on the number line are always to the left of smaller numbers. Positive numbers have a negative opposite, and negative numbers have a positive opposite. Because it is defined as the distance from zero (the origin) on a number line, the absolute value of any real number is always positive.
Hence the right statement is that the number left is always the least.

When Denine went to the pizza palace to order pizza for her party her friend Caleb noticed that for every 10 orders of cheese pizza there were 7 orders of pepperoni pizza, 5 orders of sausage pizza and 8 orders of mushroom pizza. If there were 35 pepperoni pizzas ordered how many total pizza were ordered? While waiting on the pizza something went wrong with the oven and 2 out of every 25 pizzas were burned. How many pizzas were burned? If 360 pizzas were ordered how many cheese and how many mushroom pizzas were ordered?
Using proportions, it is found that:
If there were 35 pepperoni pizzas ordered, 150 total pizzas were ordered.12 pizzas were burned.120 cheese pizzas and 96 mushroom pizzas were ordered out of 360 pizzas.What is a proportion?A proportion is a fraction of a total amount, and the measures in the context of a problem are found using basic arithmetic operations such as multiplication and division.
One application of proportions is for ratio problems, as fractions are built from the ratios to find the equivalent amounts.
Caleb noticed that for every 10 orders of cheese pizza there were 7 orders of pepperoni pizza, 5 orders of sausage pizza and 8 orders of mushroom pizza, hence the fraction of Pepperoni pizzas out of the total is given by:
Pepperoni = 7/(10 + 7 + 5 + 8) = 7/30 of the total.
If 35 pepperoni pizzas were ordered, the total number is found as follows:
7x/30 = 35
7x = 30 x 35
x = 30 x 5
x = 150 pizzas.
2 out of every 25 pizzas were burned, hence the number of burned pizzas is given by:
2/25 x 150 = 2 x 6 = 12 pizzas.
The cheese fraction is given by:
10/30.
Hence, out of 360 pizzas, the number is given by:
10/30 x 360 = 10 x 12 = 120 cheese pizzas
The mushroom fraction is given by:
8/30.
Hence, out of 360 pizzas, the number is given by:
8/30 x 360 = 8 x 12 = 96 mushroom pizzas

O(x,y) → (-x,y)
O (x, y) -> (y, -x)
Answer:
[tex](x, y) \rightarrow (-x, y)[/tex]
(Option 3)
Step-by-step explanation:
Let's take into account ΔABC.
A(-2, -2) B(-1, 1) C(3, 2)
This process is entirely trial and error. Try out the different transformations and see which one results the image from the preimage.
In this case, our transformation is (-x, y). Let's put this into trial and error:
[tex]A(-2, -2) \rightarrow A'(2, -2)\\B(-1, 1) \rightarrow B'(1, 1)\\C(3, 2) \rightarrow C'(-3, 2)[/tex]
Simply, the values we got for the image is the same as provided in the question. So we know that option 3 is the right answer.

Exponents and power - [tex]12y^3 - 4y^3 = 8y^3[/tex]
What are exponents and power?
Exponents and powers are two techniques for simplification of extremely big or extremely small numbers. For instance, we can write 3 x 3 x 3 x 3 as [tex]3^{4}[/tex], where 4 is the exponent and 3 is the base, to demonstrate 3 x 3 x 3 x 3 in a straightforward manner. There is a claim of power throughout the entire sentence [tex]3^{4}[/tex].
How do you perform exponentiation operations?
Rule 1: All operations enclosed in parenthesis must be simplified.
Rule 2 states that all exponents should be simplified, starting from the left.
Rule 3: When multiplying and dividing, always go from left to right.
Rule 4: Always add and subtract by moving from left to right.
[tex]8y^{3}[/tex] is the correct answer to the given equation.

Determine whether y varies directly with x. If so, find the constant of variation and write the equation. x=-2,-4,-16 y= -4, -8, -32
For given data y varies directly with x and the constant of variation is 2.
And the equation is y = 2x
In this question, we have been given some values of x and y.
we need to determine whether y varies directly with x.
If so, find the constant of variation and write the equation.
x = -2, -4, -16
y = -4, -8, -32
Consider the ratio y/x
-4/-2 = 2
-8/-4 = 2
-32 / -16 = 2
As y/x ratio is constant, y varies directly with x.
and the constant of variation is 2.
Also, the equation from given x, y values would be,
y = 2x
Therefore, for given data y varies directly with x and the constant of variation is 2.

ATTACHED IS THE SOLUTION x=27°
Answer:
x = 27
Step-by-step explanation:
3x - 3 and 4x - 6 are same- side exterior angles and sum to 180° , that is
3x - 3 + 4x - 6 = 180
7x - 9 = 180 ( add 9 to both sides )
7x = 189 ( divide both sides by 7 )
x = 27
Got the answer to a already just need b
a) Number of points the team has is 18
b) Number of games lost by the team is 9
a) How many point does the team have?
Number of wins the team has = W= 5
Number of draws the team has = D= 3
Number of points of the team = P
The equation is given by,
P = 3W +D
P= 3*5 + 3
P = 15+3
P = 18
Number of points the team has 18 points
b) How many games has this team lost?
Number of points of the team =P = 50
Number of draws the team has = D= 14
Number of wins the team has = W
Number of matches played by the team =T= 35
The equation is given by,
P = 3W +D
50 = 3W+ 14
3W = 50- 14
3W = 36
W = 12
Rewriting as equation,
Lost matches = Total matches - (Win matches+ Draw matches)
= T - (W+ D)
= 35 - (12+ 14)
=35 - 26
= 9
Number of games lost by the team = 9

The value of x³(x³ - 18) if x(x - 3) = -1 is -1.
To simplify simply means to make anything easier. In mathematics, simplifying an equation, fraction, or problem means taking it and making it simpler. Calculations and problem-solving techniques simplify the issue.
We have been given that
x(x - 3) = -1 ....... eq(1)
Find out the value of
x³(x³ - 18) ........eq(2)
We first simplify the value of x in equation (1)
x(x−3)=−1
Divide by x on both side
x(x−3)/x = −1/x
(x−3)=−1 /x
Rewrite as
x + 1/x = 3
Taking cube on both sides
(x + 1/x)³ = 3³
x³ + (1/x)³ = 27 - 3×3
x³ + (1/x)³ = 27 - 9
x³ + (1/x)³ = 18
Multiply by x³
x^6 + 1 = 18x³
x^6 - 18x³ = -1
x³(x³ - 18) = -1
Hence, the value of equation x³(x³ - 18) is also -1.
