Find a probable next term for the sequence 9,20,39,72,125,204,315
Answer:
464
Step-by-step explanation:
The first term is 9.
The difference between the second and first term = 20 - 9 = 11
The difference between the third and second term = 39 - 20 = 19
The difference between the fourth and third term = 72 - 39 = 33
The difference between the fifth and fourth term = 125 - 72 = 53
The difference between the sixth and fifth term = 204 - 125 = 79
The difference between the seventh and sixth term = 315 - 204 = 111
The differences are 11, 19, 33, 53, 79, 111
From the difference: 19 - 11 = 8, 33 - 19 = 14, 53 - 33 = 20, 79 - 53 = 26, 111 - 79 = 32
We can see from the first difference (8), if we add 6 we get 14, if we add another 6 we get 20, if we add 6 we get 26, if add 6 we get 32
We get the eight term using:
32 + 6 = 38
let x be the difference between the eight term and the seventh term, hence:
x - 111 = 38
x = 111 + 38
x = 149
Therefore:
eighth term - seventh term = 149
eighth term - 315 = 149
eighth term = 149 + 315
eighth term = 464
The next probable term is 464

A plumber charges $65 to make a house call plus an additional charge of $42 per hour for labor. Write an equation to represent the total cost (y) for any number of hours (x).
A plumber charges $65 to make a house call plus an additional charge of $42 per hour for labor. Write an equation to represent the total cost (y) for any number of hours (x).
Answer:
the required equation to represent the total cost with respect to every hour will be
=》y = 42x + 65
Step-by-step explanation:
total cost (y) = charge to make a house call + additional charge for every our
so, total additional charge for x hours
= 42 × x = 42x
hence y = 65 + 42x ( where 65 is charge to make a house call , y is total cost and 42x is additional charge for x hours )

Which of the following has the least value?
A. 13/15
B. 7/8
C. 2/3
D. 3/4
(I also need the work if not its ok!)
Answer:
its c
Step-by-step explanation:
Answer:
C. 2/3
Step-by-step explanation:
To solve this, we should come up with a common denominator first.
The least common denominator (LCD) of the four fractions would be 120.
So, first multiply each fraction's denominator to get 120, and multiply the numerator by the same amount.
ex. 3/4
4 x 30 = 120
3 x 30 = 90
We get 90/120.
After doing this with each fraction, we get;
13/15 = 104/120
7/8 = 105/120
2/3 = 80/120
3/4 = 90/120
Now, it is easier to see which fraction has the least value (or the one that is the smallest. Your answer is 2/3, since 80/120 is the smallest out of the four.

Answer:
5x + 2y = 7
3x � y = 2
multiply the second equation by 2 and leave the first equation as is to get:
5x + 2y = 7
6x � 2y = 4
add the second equation to the first equation to get:
11x = 11
divide both sides of that equation by 11 to get:
x = 1
replace x with 11 in the first original equation to get:
5x + 2y = 7 becomes 5 + 2y = 7
solve for y to get y = 1
your solution is x = 1 and y = 1
confirm by replacing x and y with 1 and 1 in both original equations to get:
5x + 2y = 7 becomes 5 + 2 = 7 which is true.
3x � y = 2 becomes 3 - 1 = 2 which is true.

Convert 0.55555 into a fraction
Answer:
11111/20000
Step-by-step explanation:
To convert the decimal 0.55555 to a fraction, just follow these steps:
Step 1: Write down the number as a fraction of one:
0.55555 = 0.555551
Step 2: Multiply both top and bottom by 10 for every number after the decimal point:
As we have 5 numbers after the decimal point, we multiply both numerator and denominator by 100000. So,
0.555551 = (0.55555 × 100000)(1 × 100000) = 55555100000.
Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(55555,100000) = 5. So,
(55555÷5)(100000÷5) = 1111120000 when reduced to the simplest form.
The value of the fraction is A = ( 11111 / 20000 )
What is a Fraction?An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
Given data ,
Let the fraction be represented as A
Now , the value of A is
Let the decimal number be represented as D
Now , the value of D = 0.55555
Multiply the number D by 100000 on both the numerator and denominator
And , the fraction is A = D x 100000 / 100000
A = 55555/100000
Divide by 5 on both the numerator and the denominator , we get
A = ( 11111 / 20000 )
Hence , the fraction is A = ( 11111 / 20000 )

The number 1-50 are placed in a bag. What is the probability of selecting:

B) multiple of 5________
C) a prime number _________
D) a composite number_______
A: 0
B: 10/50
C: 15/50
D: 34/50
Answers:
A) 0B) 1/5 = 0.2C) 3/10 = 0.3D) 17/25 = 0.68Nearly all of those answers involve a fraction form and an equivalent decimal form.
===========================================
Work Shown:
Part A
The largest number in the bag is 50, so we cannot select anything larger than that. The probability of getting something larger than 50 is 0% which converts to the decimal form 0
----------------------------
Part B
List out the multiples of 5 to get {5,10,15,20,25,30,35,40,45,50}
Note how 50/5 = 10, which shows there are 10 multiples listed above.
We have 10 items in that set out of 50 items in the set {1,2,3,...,49,50}. The probability of getting a multiple of 5 is 10/50 = 1/5. This converts to the decimal form 0.2
----------------------------
Part C
The prime numbers between 1 and 50 are:
{2,3,5,7,11,13,17,19,23,29,31,37,41,43,47}
There are 15 items in that list out of 50 items in the bag, so 15/50 = (5*3)/(5*10) = 3/10 is the answer. Converting to decimal form gets us 3/10 = 0.3
----------------------------
Part D
There are 50 items in the bag and 15 primes. This means there are 50-15 = 35 composite items. Well this is close to the actual count. It turns out that the number "1" is not composite, and it's not prime either. So we really have 35-1 = 34 composite values.
We get 34/50 = (17*2)/(25*2) = 17/25 as the answer. That converts to 17/25 = 0.68
