Answer:
2/375
Step-by-step explanation:
We can multiply 8/15 by 1/100 to get
[tex]\frac{8}{15} *\frac{1}{100}=\frac{8}{1500}[/tex]
Now we simplify this fraction into simplest form.
2/375
(2x² + 3x³ - 3x²-
3x - 4x-3)÷(x-2)
The simplified form of the expression [tex]\frac{(2x^{2} +3x^{3} -3x^{2} -3x-4x-3)}{(x-2)}[/tex] is [tex]\frac{3x^{3}-x^{2} -7x-3 }{(x-2)}[/tex]
As per the question statement, we are provided with an expression [tex]\frac{(2x^{2} +3x^{3} -3x^{2} -3x-4x-3)}{(x-2)}[/tex].
We are supposed to simplify the above mentioned expression.
To solve this question, let us simplify the expression, part by part, i.e., first, let us consider the numerator part which is
[2x² + 3x³ - 3x² -3x -4x - 3].
Here, it is clearly visible that the numerator expression consists of terms having same same variable but with different coefficients, such as
[2x², -(3x²)] and [-(3x), -(4x)]. Therefore, we can perform the mentioned operations on the like terms and thus simplify our numerator.
[tex][2x^{2} +(-3x^{2} )]=(2x^{2} -3x^{2} )=-(x^{2})\\[/tex]
And, [tex][(-3x) + (-4x)]=-(3x+4x)=-x(3+4)=-(7x)[/tex].
Hence, [tex](2x^{2} +3x^{3} -3x^{2} -3x-4x-3)=[+3x^{3}+(2x^{2} -3x^{2})-(3x+4x)-3]\\or, (2x^{2} +3x^{3} -3x^{2} -3x-4x-3)=[+3x^{3}+(-x^{2} )-7x-3]\\or, (2x^{2} +3x^{3} -3x^{2} -3x-4x-3)=(+3x^{3}-x^{2}-7x-3)\\[/tex]
And our denominator is (x - 2). Since, [2x² + 3x³ - 3x² -3x -4x - 3] does not equate to Zero for (x = 2), there (x - 2) is not a factor of the numerator, i.e., the numerator cannot be exactly divided by the denominator.
Therefore, the simplest form of our expression [tex]\frac{(2x^{2} +3x^{3} -3x^{2} -3x-4x-3)}{(x-2)}[/tex] is [tex]\frac{3x^{3}-x^{2} -7x-3 }{(x-2)}[/tex].

Question: The sets of numbers 6, 8, 10 and 5, 12, 13 are Pythagorean triples. Use what you know about the Pythagorean Theorem and explain or show why they are Pythagorean triples. Be sure to show your work for each set of triples! (5 points)
We know that 6, 8, 10 and 5, 12, 13 are Pythagorean triples.
The formula to see if a set of three numbers is a pythagorean triple is:
[tex]a^{2} +b^{2} =c^{2}[/tex]
For the first one, we can do
6^2 + 8^2 = 10^2 and see if it is true.
36 + 64 = 100, so this works.
The next one, we can do
5^2 + 12^2 = 13^2
25 + 144 = 169
This also works.
So in conclusion, using the formula, we can prove that they are both Pythagorean triples.
I hope this is clear to you, have a great day! :)
a = y² - x²
b = 2xy
c = x² + y²
where x and y are positive integers y > x
→ In Pythagorean triple number set 6,8,10
c² = a² + b²(10)² = (6)² + (8)²100 = 36 + 64100 = 100→ In Pythagorean triple number set 5,12,13

At a baseball game, 35% of people attending were supporting the home team, while 65% were supporting the visiting team. If 735 people attending the game supported the home team, what was the total number of people attending the game?
Answer:
1300
Step-by-step explanation:
455 divided by 35%
= 455 x 100/35
= 455 x 20/7
= 65 x 20
= 1300
The total number of people attending the game is 2100.
Given that, at a baseball game, 35% of people attending were supporting the home team, while 65% were supporting the visiting team.
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 "%".
Let the total number of people attending the game be x.
Given, 735 people attending the game supported the home team.
Now, 35% of x=735
⇒ 35/100 × x=735
⇒ 35x=73500
⇒ x=73500/35
⇒ x=2100
Therefore, the total number of people attending the game is 2100.

An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way. The most of the time, size comparisons between two numbers on the number line are to be made. Different types of inequalities are represented by a variety of notations, including: The symbol a b indicates that an is smaller than b. When a > b is used, it indicates that an is bigger than b. A is not equivalent to b in any scenario. Since a is apparently less than or solely greater than b, these relationships are known as stringent inequalities. Equivalence is not considered.

Rebecca has twice as much money as Rachel. If Rebecca gives Rachel $60, then the two of them will have the same amount of money. How much money did Rebecca have originally?
A.
B.
C.
D.
E.
Answer:
Rebecca originally had 240 dollars.
Step-by-step explanation:
Let's set B as Rebecca's money and C as Rachel's.
Rebecca has twice as much money as Rachel
B = 2C
If Rebecca gives Rachel $60, then the two of them will have the same amount of money
B - $60 = C + $60
let's combine the 2 by subtracting the second from the first
B - (B - $60) = 2C - (C + $60)
$60 = C - $60
$120 = C
so Rachel had 120 dollars.
Rebecca had twice as much, so 240 dollars.
If Rebecca gives $60 to Rachel, they have $180 each. Everything checks out.
Write each equation in exponential form.
log₆6=1
Answer:
The answer to the given question is 6
Logarithmic scale: A measurement scale in which the position is marked using the logarithm of a value rather than the actual value.
A logarithmic equation includes a logarithm in the variable x.
An exponential equation is one in which the variable is represented by an exponent. A logarithmic equation is one in which the logarithm of a variable-containing expression is used.
For logarithmic equations, log b (x) = y is equivalent to b^y = x such that x > 0, b > 0 and b is not equal to 1.
In the given problem, b = 6, x = 6 and y = 1
b = 6
x = 6
y = 1
Substituting the values of b, x and y into the equation b^y = x;
6^(1) = 6

(A) 9√3 (B) 8√9 (C) 15√3⁸ (D) 9√3¹⁵
The product of ∛3 and 5√3 is 15√3⁸ (Option C).
This question can be easily solved by using the concept of roots. The two terms mentioned in the question are ∛3 ( cubic root of 3 ) and 5√3 (5th root of 3 ). This question can be solved in 4 easy steps
Step 1 : Identify the power of the root and take LCM of those numbers.
In this case, the powers of root for ∛3 and 5√3 are 3 and 5, respectively. Take LCM of 3 and 5.
LCM = 3 x 5 = 15
=> We get the LCM of 3 and 5 as 15.
Step 2 : Write the given numbers in the form of fractional powers
∛3 = 3¹ˡ³ => The power of 3 = 1/3
5√3 = 3¹ˡ⁵ => The power of 5 = 1/5
Step 3 : Multiply and divide the powers of the base number ( in this case 3 ) with a number such that you get the denominator as the LCM ( in this case 15 )
1/3 can be multiplied and divided by 5 to get the denominator as 15
=> 1 * 5 / 3 * 5 = 5 /15
1/5 can be multiplied and divided by 3 to get the denominator as 15
=> 1 * 3 / 5 * 3 = 3 /15
Step 4 : Find the product of the two terms
15√3⁵ x 15√3³ = 15√3³⁺⁵ = 15√3⁸
Therefore, using the concept of roots and fractions, we get the product of ∛3 and 5√3 as 15√3⁸.
