the constant of variation or namely its slope will be

\bf (\stackrel{x_1}{3}~,~\stackrel{y_1}{18})\qquad (\stackrel{x_2}{5}~,~\stackrel{y_2}{30}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{30-18}{5-3}\implies \cfrac{12}{2}\implies 6

Greeley [361]

Answer: The sales tax would be $2.40

A-5/a divided by 4/a
maria [59]

Answer:

\frac{a-5}{4}

Step-by-step explanation:

the given equation is

\frac{a-5}{a} /\frac{4}{a}

from the multiplication rules we know that

\frac{a}{b}/\frac{c}{d}=\frac{a}{b}*\frac{d}{c}

so for the given equation changing the sidn of division to multiplication

the equation becomes

\frac{a-5}{a} * \frac{a}{4}

a cancels out from both numerator and denominator

so it becomes

\frac{a-5}{4}

which is the answer

My couch potato friend enjoys sitting in front of the TV and grabbing handfuls of 6 chocolates at random from his snack jar. Unb
Nikolay [14]

Answer:

There are 8008 possible outcomes are there the first time he grabs 6 chocolates

Step-by-step explanation:

The order in which the chocolates are chosen is not important. So the combinations formula is used to solve this question.

Combinations formula:

C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

How many possible outcomes are there the first time he grabs 6 chocolates?

6 chocolates from a set of 16. So

C_{16,6} = \frac{16!}{6!(16 - 6)!} = 8008

There are 8008 possible outcomes are there the first time he grabs 6 chocolates
