How many sixths are in 3 and 1 third ??

Answers

1 whole thing = 6 sixths
3 whole things = 18 sixths

1 third of a whole thing = 2 sixths of it

3 wholes plus 1 third = 18 sixths plus 2 sixths = 20 sixths
Change 3 1/3 to improper fraction which equals 10/3. Then multiply numerator and denominator by 2
10/3 = 20/6, so there are 20 sixths in 3 and 1 third.

Given the functions f(x) = 7x + 13 and g(x) = x + 2, which of the following functions represents f[g(x)] correctly?f[g(x)] = 7x + 15
f[g(x)] = 7x + 27
f[g(x)] = 7x2 + 15
f[g(x)] = 7x2 + 27

Answers

f[g(x)] = f[x + 2] = 7(x + 2) + 13 = 7x + 7(2) + 13 = 7x + 14 + 13 = 7x + 27

f[g(x)] = 7x + 27

The correct answer is B.

A group of employees bought a get-well gift for a co-worker. The gift cost $16.06. If there are 22 employees in the group, how much does each employee need to contribute?

Answers

The total amount each employee contributes to buy the gift is given by the equation A = $ 0.73

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Let the amount contributed by each employee be A

Now , the total amount for the gift = $ 16.06

The total number of employees = 22 employees

So , amount contributed by each employee A = total amount for the gift / total number of employees

On simplifying the equation , we get

The amount contributed by each employee A = 16.06 / 22

The amount contributed by each employee A = $ 0.73

Hence , the amount contributed by each employee is $ 0.73

What is the distance between the points ( 38,30) and (14,20)?

Answers

To find out the distance of two coordinates, we can use this equation.

Distance S = [ (y2-y1)^2 + x2-x1)^2 ] ^ 0.5

x1 , y1 = 38 , 30
x2 , y2 = 14 , 20

Distance S = [ (20-30)^2 + (14-38)^2 ] ^0.5
                   = [ 10^2 + (-24)^2 ] ^ 0.5
                   = [ 100 + 576 ] ^ 0.5
                   = 676 ^ 0.5
                   = 26
(24,10)

Hope this helps!
