What would this question look like after we change the mixed number to improper & use KCF to rewrite the question?

iris [78.8K]

Answer:

The question $3\frac{1}{2}\div\frac{1}{3}$ after change the mixed number to improper & using KCF will become : $\mathbf{=\frac{7}{2}\times \frac{3}{1}}$

Option B is correct option.

Step-by-step explanation:

We need to change the mixed number to improper & use KCF to rewrite the question.

The expression is: $3\frac{1}{2}\div\frac{1}{3}$

First converting mixed fraction into improper fraction

Multiply whole number with the denominator i,e (3*2=6) now add the numerator i.e (6+1) = 7/2

Solving:

$3\frac{1}{2}\div\frac{1}{3}\\=\frac{7}{2}\div\frac{1}{3}$

Using KCF

KCF stands fro Keep it, Change it, Flip it.

It is used when division sign is converted to multiplication the term (1/3) is reversed to (3/1)

So, our expression will be

$=\frac{7}{2}\times \frac{3}{1}$

So, The question $3\frac{1}{2}\div\frac{1}{3}$ after change the mixed number to improper & using KCF will become : $\mathbf{=\frac{7}{2}\times \frac{3}{1}}$

Option B is correct option.

You are right about the domain

it is all real values of x except 4

So about the range we must make x subject of the formular so we know the values of y in which g(x) is defined

The density of pure solid copper is 8.94 g/mL. What volume does 5 kg of copper occupy. Please help

mel-nik [20]

Density= Mass divided by Volume, but you're trying to find Volume so you apply Algebra and get Volume= Mass divided by Volume.

Volume= 0.5592841163 [kg/m (power to the 3)]

You should round it up

Give the coordinates of a point on the line whose equation in point-slope form is y − (−3) = 1 4 (x − 9).

statuscvo [17]

Answer:

Below

Step-by-step explanation:

● y -(-3) = (1/4) (x-9)

Replace 1/4 by 0.25 to make it easier

● y + 3 = 0.25(x-9)

● y + 3 = 0.25x - 2.25

Add 3 to both sides

● y +3-3 = 0.25x -2.25-3

● y = 0.25x -5.25

To the coordinates of a point from this line replace x by a value.

The easiest one is 0.

● y = 0.25×0 -5.25

● y = 5.25

5.25 is 21/4

So the coordinates are (0, 21/4)
