Here's the equation: 6÷1/3

We need to make 6 an improper fraction. We will do this by simply putting a 1 under it (6/1). This is still the same value, just in fraction form.

Now, we divide.

When dividing fractions, we need to remember the rule: Keep, Change, Flip.

So, we KEEP 6/1

CHANGE to multiplication

and FLIP 1/3 to 3/1

Now, we have our problem:

6/1*3/1

This turns out as 18/1 which can be simplified to 18.

This means he has 18 pieces

hope I helped.

have a great day!

Which of the following pairs of functions are inverses of each other?
AnnyKZ [126]

Answer:

Step-by-step explanation:

Rearrange each function to solve for x.

Switch x and y,

The resulting equation is the inverse function.

A:

f(x) = y = 5+x

x = y-5

y = x-5

f⁻¹(x) = x-5

g(x) = 5-x ≠ f⁻¹(x)

g(x) is not the inverse of f(x).

:::::

B:

f(x) = y = 2x-9

x = (y+9)/2

y = (x+9)/2

f⁻¹(x) = (x+9)/2

g(x) = (x+9)/2 = f⁻¹(x)

g(x) is the inverse of f(x).

:::::

C:

f(x) = y = 2/x - 6

x = 2/(y+6)

y = 2/(x+6)

f⁻¹(x) = 2/(x+6)

g(x) = (x+6)/2 ≠ f⁻¹(x)

:::::

D:

f(x) = y = x/3 + 4

x = 3y - 12

y = 3x - 12

f⁻¹(x) = 3x - 12

g(x) = 3x - 4 ≠ f⁻¹(x)

g(x) is not the inverse of f(x).

What is the perimeter of a square if it has an area of 36 square centimeters?
kirill115 [55]
Let x is the side of the square
so A = x * x or A = x^2 = 36
As you know 36 is a perfect square root = 6^2
Then  x = 6 cm

Perimeter = 4x = 4(6) = 24 cm
