1. I am a number between 120 to 130 and I am divisible by 3, 6 and 9. Who am I?
Answers
126/3=42
126/6=21
126/9=14
Answer:
126
Step-by-step explanation:
A number is divisible by 3 if its sum of digits is divisible by 3 (you can do it over and over again until it's one digit!).
A number is divisible by 2 if its last digit is 0, 2, 4, 6 or 8.
A number is divisible by 6 if it is divisible by 2 and by 3.
A number is divisible by 9 if its sum of digits is divisible by 9 (you can do it over and over again until it's one digit!).
So we need a number with last digit 0, 2, 4, 6, or 8 (because it's divisible by 6 hence by 2) and with a sum of digits divisible by 9 (because if it's divisible by 9 it's also divisible by 3).
130 is not divisible by 9, so the first digits must be 12X.
to get a number divisible by 9, we need to add a digit D so that 1+2+D is divisible by 9.
9 - 1 - 2 = 6
126 is divisible by 9 because it's sum of digits is 9. It's also divisible by 6, because it is divisible by 3 and its last digit is 6.

Kayla has a red number cube and a blue number cube. Each number cube has faces labeled 1 through 6.
What is the probability Kayla rolls an even number on the red cube and a multiple of 3 on the blue cube?
Answers
So probability that kayla rolls an even number on the red cube and a multiple of 3 on the blue cube is 16.66 ≈ 16%
Given that we have red number cube and blue number cube so as we all know that Probability is the ratio of the favourable number of outcomes to the total number of outcomes is known as Probability.
First, find the possible outcomes.
Kalya has a red number cube and a blue number cube. Each number cube has faces labeled 1 through 6
So, possible outcomes =6×6 =36
Let, S be the sample space.
Then, ⁿ(s) =36
Let, E = the event of getting an even number on the red cube and a multiple of on the blue cube.
E = (2,3),(2,6),(4,3),(6,3),(6,6)
Then, ⁿ(E)=6
Let, P is the probability of the event .
So, P(E)= [tex]\frac{n(E)}{n(S)}[/tex] = [tex]\frac{6}{36}[/tex] = [tex]\frac{1}{6}[/tex] = 16.67 percent or 16[tex]\frac{2}{3}[/tex] %

The given expression expressed in the form (x+A)^2+B is (x - 6)² + 65
A = -6 and B = 65
Completing the squareFrom the question, we are to express the given expression in the form (x + A)^2+B by completing the square
The given expression is
x² -12x + 101
Using the completing the square method
x² -12x + 101
Divide the coefficient of x by 2 and then square it
The coefficient of x is -12
Dividing by 2, we get
-12/2 = -6
Squaring
(-6)²
Now, add and subtract this value from the expression
x² -12x + (-6)² + 101 - (-6)²
Then, we can write that
(x - 6)² + 101 - (-6)²
(x - 6)² + 101 - 36
(x - 6)² + 65
Thus,
The given expression expressed in the form (x+A)^2+B is (x - 6)² + 65

how much of an alloy that is 40% copper should be mixed with 400 ounces of an alloy that is 70% copper in order to get an alloy that is 60% copper
Answers
The mixture requires 200 ounces of 40% alloy.
What is defined as the mixture?A mixture is a physical combination of two or more substances that retain their identities and are blended as solutions, suspensions, or colloids.
An alloy is a metallic substance made up of two or more elements that can exist as a compound or a solution. Alloy components are typically items, though carbon, a nonmetal, is a necessary component of steel.x = amount of 40% copper
400 = amount of 70% copper
x + 400 = total amount of copper = amount of 60% copper
Set a correctly weighted mixture of x and 300 equal to the a weighted (x+300), in which the weights are decimal percentages;
40% is 0.4, 70% is 0.7, and60% is 0.60.4x + 0.7(400) = 0.6(x + 400)
Solve for x:
0.4x + 280 = 0.6x + 240
0.2x = 40
x = 200
x = 200 ounces of 40% copper.
Therefore, the amount of 40% alloy needed for the mixture is 200 ounces.

Answer: x = [tex]\frac{-31}{23}[/tex], y = [tex]\frac{-9}{23}[/tex], z = [tex]\frac{-83}{23}[/tex]
Step-by-step explanation :Solving system of equations
Given the following system of equation below
- 4x + 2y + z =1 .......(1)
x − y + 3x = −5 ........(2)
3x + y − 4z = 10.........(3)
first we solve eq 1 and eq 3:
we get, -13x + 9y = 14 ..........(4)
Now we solve eq 2 and eq 4 and get value of x and y:
we get, x = [tex]\frac{-31}{23}[/tex] and y = [tex]\frac{-9}{23}[/tex]
finally we put value of x and y in eq 1 and get the value of z:

106/23 + z = 1
z = 1 - 106/23
z =[tex]\frac{-83}{23}[/tex]

If f(1)=1 and f(n)=4f(n-1) what is the value of f(4)?
Answers
Answer:
64
Step-by-step explanation:
You have the recursive formula f(1)=1; f(n)=4f(n-1) and you want f(4).
RecursionThe value of f(4) can be found a couple of ways. Perhaps the simplest is to compute the first 4 terms of the sequence using the recursive formula.
f(1) = 1
f(2) = 4·1 = 4
f(3) = 4·4 = 16
f(4) = 4·16 = 64
The value of f(4) is 64.
Explicit formulaThe multiplying factor of 4 on the previous term tells you this is a geometric sequence with a common ratio of 4. The explicit formula is then ...
f(n) = f(1)·r^(n-1) . . . . . n-th term of sequence with common ratio r
f(n) = 1·4^(n-1) . . . . . . formula for f(1)=1 and r=4
For n=4, this is ...
f(4) = 1·4^(4-1) = 4^3
f(4) = 64
