What is the greatest common factor of 18 and 50

Answers

Answer:2

Step-by-step explanation:

18 divided by 2 equals 9

and for 50 it’s 15  because 50 divided by 2 is 15 so it’s 2

The greatest common factor of 18 and 50 is 2.

What is the Greatest Common Factor (GCF)?

Greatest Common Factor is defined as the greatest number that is a factor of both numbers when two numbers are involved.

A number that divides into another number completely is said to be a factor.

To put it another way, any two integers that multiply to produce a result are factors of the result.

We have to determine the greatest common factor of 18 and 50

The prime factorization of 18 is

⇒ 2 x 3 x 3 = 18.

The prime factorization of 50 is

⇒ 2 x 5 x 5 = 50.

The occurrence of common prime factors of 18 and 50 is 2.

So the greatest common factor of 18 and 27 = 2.

Therefore, the greatest common factor of 18 and 50 is 2.

Help!!!!!!!!!find the equation of the linear function q(16)=1 that is parralel to f(x)=1/3x+39


It wants it in slope intercept form

Answers

Answer:

[tex]q(x)= \frac{1}{3} x -\frac{13}{3}[/tex]

Step-by-step explanation:

So you have (16, 1)

When two linear functions are parallel, they have the same slope.

So function q also has a slope of 1/3x. You have a set of points so you can plug them in a slope intercept equation to find b.

y= mx+b

m= slope

y= y-intercept

1= 1/3(16) +b

1 - (16/3) = b

b= -13/3

so then, [tex]y= \frac{1}{3} x -\frac{13}{3}[/tex]

If 5b = 6a + 16 and 9a = 7b - 20, then what are the values of a and b?

Answers

9514 1404 393

Answer:

  (a, b) = (4, 8)

Step-by-step explanation:

Writing both equations in general form, we have ...

  6a -5b +16 = 0

  9a -7b +20 = 0

__

We can make a little array of the numbers in the equations:

  [tex]\left[\begin{array}{cccc}6&-5&16&6\\9&-7&20&9\end{array}\right][/tex]

Note that the first column is repeated at the end.

Now, we can "cross multiply" and form the differences of products in adjacent columns:

  d1 = (6)(-7) -(9)(-5) = 3 . . . . . . left 2 columns

  d2 = (-5)(20) -(-7)(16) = 12 . . . . . middle 2 columns

  d3 = (16)(9) -(20)(6) = 24 . . . . . right 2 columns

Then the solutions to these equations are the solutions to ...

  1/d1 = a/d2 = b/d3

  a = d2/d1 = 12/3 = 4

  b = d3/d1 = 24/3 = 8

The values of a and b are 4 and 8, respectively.

Additional Comment

There are a number of ways to solve linear equations. This is similar to what you would get by doing "elimination". It is also similar to Cramer's Rule and Vedic math techniques. The number of math operations is about the same*. Once you learn the technique, it is fairly fast and requires no decision-making. My other favorite method is using a graphing calculator.

__

* This method uses 6 multiplications, 3 subtractions, 2 divisions. In the general case of "elimination", where the coefficients are not "nice" (as here), you would perform 7 multiplications, 4 subtractions and 2 divisions. This method is less work when the coefficients don't cancel easily.

10 girls and 15 boys sit a test.

The mean mark for the boys is 70. The mean mark for the girls is 82.

Work out the mean mark for the whole class.

Answers

Answer:Mean  mark  of whole class= 74.8

Step-by-step explanation:

Mean  = Total marks of student / Number of students

Total marks of boys = Number of boys x Mean mark for boys

=15 x 70=1,050

Total marks of girls  = Number of girls  x Mean mark for girls

=10 x 82=820

Mean of whole students  = Total marks of student / Number of students

= (1,050 + 820)/ (10+15)

=1870/25

=74.8

2. Adam borrows $6,000 from his parents today for university fees and he promises
to pay a lump sum of $6,900 in 3 years' time. Calculate the following quantities
for the repayment arrangement:
(a) the effective annual interest rate.
(b) the equivalent simple annual interest rate.

Answers

Answer:

A) 4.77%.

B) 5%.

Step-by-step explanation:

Given that Adam borrows $ 6,000 from his parents today for university fees and he promises to pay a lump sum of $ 6,900 in 3 years' time, to calculate the effective annual interest rate and the equivalent simple annual interest rate the following calculations must be performed:

A)

6,900 = 6,000 x (1 + X / 1) ^ 3x1

6,900 = 6,000 x 1X ^ 3

6,900 = 6,000 x 1 x 4.77 ^ 3

Thus, the interest rate of said investment is 4.77% per year.

B)

(6,900 - 6,000) / 3 = 300

6,000 = 100

300 = X

300 x 100 / 6,000 = X

30000 / 6,000 = X

5 = X

Thus, the simple interest rate would be 5% per year.
