Answer: X= 6
Step-by-step explanation:
Answer:
x = 6
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.
First, multiply 8 to both sides:
(x/8)8 = (3/4)8
x = (3 * 8)/4
First, divide 8 with 4:
x = 3 * (8/4) = 3 * 2
Finally, simplify by multiplying:
x = 3 * 2
x = 6
x = 6 is your answer.

How do you know if a given relation is a function or not a function?
Answer:
In general, a relationship f (x) = y is a function only if, for each value of x that you plug into it, you get only one value for y.
Step-by-step explanation:
Sometimes the only way to tell if a given relationship is a function or not is to try various values for x to see if they yield unique values for y.

Max's grandparents have $6000 that they want to give to him and his brother Sam. They like Sam more than Max, so they plan to give Sam 4 times the amount they will give Max. Determine the amount of money that Sam will get. Sam's Amount=$
Answer: Same will get $4800
Step-by-step explanation:
If Sam will get 4 times the amount of money they will give Max then we can come up with the equation s = 4m where s is the amount that same get and m is the amount that Max will get.
And we know that if they combine their money they will have $6000 in total so we can also come up the equation s + m = 6000
So using the equation
s= 4m and s+m=6000 substitute the value of x into the second equation and sole for m ..
4m + m = 6000
5m = 6000
m = 1200
So we know that Max will get $1200 and Sam will get 4 times as much as that.
s= 4(1200)
s = 4800
Which set of numbers does not contain 70? A) whole numbers B) irrational numbers C) integers D) natural numbers
Answer:
B) Irrational numbers
Step-by-step explanation:
The given number is [tex]70[/tex].
We know the number which doesn't have any fractional part or decimal part is an integer. Here, there is no fractional part with the number 70, so this is an integer.
This is one of counting numbers from the set of [tex]\{ 1,2,3,4,5,...\}[/tex], so this is a natural number.
Also, this belongs to the set of whole numbers [tex]\{0,1,2,3,...\}[/tex].
But, [tex]70[/tex] can be written in the form of [tex]\frac {p}{q}[/tex] as [tex]70= \frac {70}{1}[/tex] where [tex]p=70[/tex] , [tex]q=1[/tex] are integers and [tex]q \neq 0[/tex], so this is a rational number.
We know that any number that belongs to the rational number is not an irrational number.
Hence, [tex]70[/tex] does not belong to the set of irrational numbers.
So, option [tex](B)[/tex] is correct.

A researcher needs 60 L of 50% concentrate solution for a certain experiment, but she has only 30% solution and 70% solution. How many liters of the 30% and the 70% solutions should she mix to get what she needs?
Answer:
30 liters of 30% solution and 30 liters of 70% of solution should be mixed by the researcher to get 60 liters of 50% solution.
Step-by-step explanation:
Let 'x' liters of 30% solution and 'y' liters of 70% solution are added together to get the required 60 liters of 50% of the solution.
According to the question, 30% solution and 70% solution are mixed and so, we get
[tex]0.3x+0.7y=0.5 \cdot 60\\\Rightarrow 0.3x+0.7y=30----(1)[/tex]
Also, sum of the final solution should be 60 liters only so, we get
[tex]x+y=60----(2)[/tex]
Solving equations (1) and (2), we get
[tex]x=30 liters\\ y=30 liters[/tex]
Hence, we can say that 30 liters of 30% solution and 30 liters of 70% of solution should be mixed by the researcher to get 60 liters of 50% solution.

Axioms and postulates are statements that are accepted as true without proof. B: this statement is false. Axioms and postulates are statements that have not been shown to be true or false. C: this statement is true. D: this statement is false. Axioms and postulates are statements that are discarded as false because they have been disproved.
Answer:
C: this statement is true
Step-by-step explanation:
Axioms and postulates are statements that are accepted as true because they have been proven using logic and deductive reasoning.
They present themselves as self-evident. These are universally accepted and general truth.============
A: this statement is false. Axioms and postulates are statements that are accepted as true without proof.
False. They have been proven numerous of timesB: this statement is false. Axioms and postulates are statements that have not been shown to be true or false.
False. There are many evidences that they are trueC: this statement is true.
TrueD: this statement is false. Axioms and postulates are statements that are discarded as false because they have been disproved
False. They have not been disprovedConsider a rectangle with width of x units and an area of 10 square units. The length l of the rectangle can be modeled by the function f (x) = StartFraction 10 Over x EndFraction.
Answer:
When we have a rectangle of width W and length L, the area of this rectangle can be calculated as:
A = W*L
In this case we have:
W = x
L = 10/x.
Then the area of the rectangle will be:
A = W*L = x*(10/x) = 10
So the value of x cancels in the equation, which means that we can not find the value of x.
Now, as L = 10/x we can find some restrictions:
if x = 0, we would have L = 10/0
So we can not have x = 0.
And as W = x, this represents a positive measure, we also have that x can not be a negative number.
So the relation:
W = x
L = 10/x
Gives us all the possible combinations of width and length such that the area of the rectangle is exactly 10 square units.

Step-by-step explanation:
Zara has forgotten her 4-digit PIN code. She knows the first digit is a factor of 20 and the 4 digits make a number divisible by 5. How many different sets of 4 digits could it be?
Answer:
800 different sets of digits.
Step-by-step explanation:
Since the first digit is a factor of 20, the factors of 20 are 1,2,4,5,10,20. We only need the single digit factors which are 1,2,4 and 5. These 4 numbers can be permuted in 1 way for the first digit, so we have ⁴P₁.
For the second digit, we have 10 digits permuted in 1 way, ¹⁰P₁ and also for the third digit, we have 10 digits permuted in 1 way, ¹⁰P₁ and for the last digit, which is divisible by 5, it is either a 0 or 5, so we have two digits permuted in 1 way, ²P₁.
So, the number of different 4 digit number that Zara'2 4-digit PIN code could be is ⁴P₁ × ¹⁰P₁ × ¹⁰P₁ × ²P₁ = 4 × 10 × 10 × 2 = 800 different sets of digits
800 different sets of 4 digit PIN could be made.
The First (single) digit is a factor of 20. So, it is among 1, 2, 4, 5. The other factors 10 & 20 are ignored, as they are 2 digits.So, ways of choosing 1 out of 4 digits = 4 P 1 = 4
The Second digit can be any digit among he 10 digits : 0, 1, 2, 3, 4, 5, 6, 7, 8, 9So, ways of choosing 1 out of 10 digits = 10 P 1 = 10
Third digit can also be any digit among he 10 digits : 0, 1, 2, 3, 4, 5, 6, 7, 8, 9So, ways of choosing 1 out of 10 digits = 10 P 1 = 10
The Fourth digit can be amongst only 0 & 1, as the final PIN is divisible by 5.So, ways of choosing 1 out of 2 digits = 2 P 1 = 2
Hence, total number of ways = 4 x 10 x 10 x 2 = 800 ways

Find the formula for the nth term of the sequence: 0,7,18,33,52
Answer:
t(n) = 2n² + n - 3
Step-by-step explanation:
Given sequence:
0, 7, 18, 33, 52Find the formula for nth term t(n)
SolutionSequence is neither arithmetic nor geometric, analyzing:
0, 7, 18, 33, 52First level difference
7, 11, 15, 19Second level difference
4, 4, 4As there are two levels, the formula should be in the form of:
t(n) = an² + bn + cTrying the formula with the known terms:
t(1) = 0 ⇒ a+b + c= 0t(2) = 4a + 2b + c = 7 ⇒ 3a + b = 7t(3) = 9a + 3b + c = 18 ⇒ 3(3a+b) + c = 18 ⇒ 21 + c = 18 ⇒ c = -3Going back to previous equations to find remaining coefficients:
t(1) ⇒ a+ b = 3 ⇒ t(2) = 2a + (a+b) = 7 ⇒2a + 3 = 7 ⇒ a= 2 ⇒ b = 1So the formula becomes:
t(n) = 2n² + n - 3
