Answer:
5.7u+5.3v+1.5Step-by-step explanation:
Given a triangle with side lengths s1, s2 and s3, the perimeter of the triangle in centimetre is expressed as the sum of all the sides of the triangle i.e
Perimeter of a triamgle = s1+s2+s3
Given the sides of the triangle in question as (1.4u+9.6) centimeters, (4.3u-9.9)centimeters, and (5.3v+1.8) centimeters, the perimeter of the triangle will be the sum of all the functions as shown;
Let s1 = (1.4u+9.6)cm
s2 = (4.3u-9.9)cm
s3 = (5.3v+1.8) cm
Perimeter of the triangle = 1.4u+9.6 + 4.3u-9.9 + 5.3v+1.8
collect like terms
P = 1.4u+ 4.3u+5.3v+9.6-9.9 +1.8
P = 5.7u+5.3v+1.5
Hence the expression that represents the perimeter of the triangle is 5.7u+5.3v+1.5
Factor of 3x-3a+xy-ay
Answer:
(3 - y) & (x - a) are the factors
Step-by-step explanation:
3x-3a+xy-ay
=> 3x - xy - 3a - ay
=> x(3 - y) - a(3 - y)
=> (3 - y)(x - a)
(3 + y) & (x - a) are the factors of the expression 3x-3a+xy-ay.
Here, we have,
given that,
the expression is : 3x-3a+xy-ay.
now, we have,
To factor the expression 3x - 3a + xy - ay, we can group the terms as follows:
3x-3a+xy-ay
=> (3x - 3a) + (xy - ay)
Now, let's factor out the common factors from each group:
=> 3(x - a) + y(x - a)
Notice that both terms now have a common factor of (x - a).
We can factor out this common factor:
=> (x - a)(3 + y)
Therefore, the factored form of the expression 3x - 3a + xy - ay is (x - a)(3 + y).
Hence, (3 + y) & (x - a) are the factors of the expression 3x-3a+xy-ay.

In the text box below, write a brief summary about the similarities and differences between Inequality Notation, Set-Builder Notation, and Interval Notation.
Answer and Step-by-step explanation:
Differences:
Interval notation is a set of real numbers that contains all real numbers lying between any two numbers of the set. For example set of all real numbers can be described in interval notation as 0 ≤ x ≤1. Interval notation press the solution set to equality, and it is important to express solution sets in calculus. Set builder notation is a mathematical notation for describing a set by its elements, and their member satisfies' properties.It describes the elements of a set instead of listing the element. For example the set {1, 2, 3, 4, 5, 6, 7, 8, 9} is written in builder notation will be {x/x is a counting number less than 10}.Inequality notation is a relation that makes a non equal comparison between two numbers. Set are also defined by using some inequalities like >, <, ≤, ≥. These are called inequality notations.
Similarities:
The purpose of inequality notation, set builder notation, and interval notation is the same because these notations used to describe a set and the characteristics of each element of a set. When a set is representing in set builder notation, it defines characteristics of elements. If the set is represented in interval notation, we need to know the upper and lower bound set. In inequality notation, the set is described by the graph on a number line.

What is the value of the expression below when y=8 and z=8? 10y-3z
Answer:
56
Step-by-step explanation:
We are given the expression:
10y-3z
and asked to find the value when y=8 and z=8. Therefore, we must substitute 8 in for both y and z.
10(8)-3(8)
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Addition and Subtraction.
Multiply 10 and 8.
(10*8) -3(8)
80-3(8)
Multiply 3 and 8.
80 - (3*8)
80- 24
Subtract 24 from 80.
(80-24)
56
The value of the expression 10y-3z when y=8 and z=8 is 56.

Answer:
Step-by-step explanation:
Like terms have same variables
16x & -4x are like terms
11p & -3p are like terms
16x + 11p - 4x -3p = 16x - 4x + 11p - 3p
= (16- 4)x + (11 - 3) p
= 12x + 8p
The volume of a cone is 200.96 cubic yards. What is the radius of the cone if the height is 12 yd? Use pi =3.14 and round your answer to the nearest hundredth.
Answer:
If I'm doing the problem correctly, the radius should be 4 yards.
Step-by-step explanation:
You work the problem backwards. Multiply 200.96 by 3, since it's a cone, so you're working with the volume of what a cylinder would be with the same dimensions. Then divide by the height (12 yd), then divide by pi. You should end up with 16, and 4 squared equals 16. Work the problem forwards from there to check.
4 squared is 16. 16 times 3.14 is 50.24. 50.24 times 12 is 602.88. 602.88 divided by 3 is 200.96.

Drag the numbers to order them from least to greatest.
Answer:
[tex]\sqrt{7}[/tex], 2.8, [tex]\pi[/tex], [tex]\sqrt{17}[/tex], 4.6
Step-by-step explanation:
To order the numbers from least to greatest turn all the numbers into decimal form.
[tex]\sqrt{7}[/tex]: 2.65
[tex]\sqrt{17}[/tex]: 4.12
[tex]\pi[/tex]: 3.14
4.6
2.8
Now order them from least to greatest (make sure you put the numbers back into their original form)
[tex]\sqrt{7}[/tex], 2.8, [tex]\pi[/tex], [tex]\sqrt{17}[/tex], 4.6
The numbers in the form of least to greatest will be [tex]\sqrt{7}[/tex], [tex]2\overline{.8}[/tex], π, [tex]\sqrt{17}[/tex], 4.6.
What are rational and irrational numbers ?Rational numbers are those numbers which have terminating,Repeating or recurring digits after the decimal place.
Irrational numbers have non-repeating, non-recurring non-terminating digits after the decimal place.
According to the given question we have to order the number from least to greatest.
Given number are 4.6, [tex]2\overline{.8}[/tex], π, [tex]\sqrt{17}[/tex], [tex]\sqrt{7}[/tex].
We know the value of π is 3.14 approx and square root of 17 lies between square root of 16 and 25 which are 4 and 5 but more close to 4 and square root of 7 lies between square root of 4 and 9 which are 2 and 3.
∴ The given numbers in increasing order will be
[tex]\sqrt{7}[/tex], [tex]2\overline{.8}[/tex], π, [tex]\sqrt{17}[/tex], 4.6.

The formula for the area of a triangle is A = 1/2bh, in which b represents the length of the base and h represents the height. If a triangle has an area of 328 mm^2 and the height is 16 mm, what is the measure of the base?
Answer:
b = 41 mmStep-by-step explanation:
From the question
Area of a triangle is given by
[tex]A = \frac{1}{2} bh[/tex]
where
b is the length of the base
h is the height
From the question
Area = 328 mm²
height = 16 mm
Substitute the values into the above formula and solve for the height
We have
[tex]328 = \frac{1}{2} \times 16b \\ 328 = 8b[/tex]
Divide both sides by 8
We have the final answer as
b = 41 mmHope this helps you
7 times the difference of a number and 1
answer: 7(x-1)
hope this helps you
Answer: The answer is 7(x - 1).
Step-by-step explanation:
So far, we know that the givens are:
7 times the difference of a number and 1
We just need to understand what it says:
7 times ( difference of a number and 1)
So "the number" can be any number, but you have to replace it with a variable such as n, s, x, etc. And by the way, difference is from subtraction, the result of the subtraction of 1 from the unknown number. Using this, we get:
7(x - 1)
Hence the answer!

For how many games is the total cost of bowling equal for the two bowling establishments? Family bowling game $4, shoes $1. Knight owl bowling game $3.75, shoes $2.
Answer: If you play 4 games, the price will be the same in the two establishments.
Step-by-step explanation:
Ok, in Family Bowling we have:
$4 per game, plus $1 per shoes (the shoes are paid only one time).
Then, the price for X games, is:
Pa(X) = $4*X + $1.
In Knight Owl Bowling we have:
$3.75 per game and $2 for the shoes, the price for X games will be:
Pb(X) = $3.75*X + $2.
Now, if we want to pay the same in both establishments, we have:
Pa(X) = Pb(x)
$4*X + $1 = $3.75*X + $2
Now we should solve this for X.
$4*X - $3.75*X = $2 - $1 = $1
($4 - $3.75)*X = $1
$0.25*X = $1
X = $1/$0.25 = 4.
If you play 4 games, the price will be the same in the two establishments.

The n" term is given by Tn=n(n + 1)(2n + 1).
Work out the value of T23.
Step-by-step explanation:
tn=n(n+1)(2n+1)
t23=23(23+1)(2*23+1)
t23=36754
Answer:
The 23rd term is 2806.
Step-by-step explanation:
The other answerer has used the formula but i'm answering from the assumption that T1 to T4 are correct.
Each term is the sum of n terms of an arithmetic series with first term a1 = 12 and common difference d = 10.
Sum of n terms = (n/2)[2a1 + d(n - 1)]
So the sum of 23 terms =
= 23/2 (2*12 + 10 * 22)
= 11.5 * 244
= 2806.
