Mrs. Potts can make 5 dozen ravioli in 1 hour. Write and solve a direct variation equation to find many she can make in 2 1/2 hours.

Answers

A direct variation generally has the equation Y=KX
Because Mrs. Potts makes 5 dozen ravioli in 1 hour, this will be the K value.
(5 dozen/1 hr)
To figure out how many she can make in 2 1/2 hrs. You use 5 dozen/1 hr as the K value and multiply that by 2 1/2 hrs (the X value).
The hrs will cancel out and you will be left with the number of ravioli made in 2 1/2 hrs.

Who made more choices commission this month? How much did she make? Salesperson A made 11% of $67,530. Salesperson B made 8% of $85,740.

Answers

Answer Step-by-step explanation:

$Salesperson~A=$ $11$ % $of~67,530=(11)/(100) *67530=0.11$

$=0.11*67530=7,428.3$

$Salesperson~B=$ $8$ % $of~85,740=(8)/(100)*85740= 0.08$

$=0.08*85740=6,859.2$

$7,428.3$ > $6,859.2$

$Thus,~Salesperson~A~made~more~commission~than~Salesperson~B.$

Explain why the product is always less than one when you multiply a fraction by another fraction

Answers

Because when you do that ...

-- you're starting with a piece that's less than ' 1 ', and

-- you're calculating a piece of it that's less than the whole original piece.

so a proper fraction (one that is less than one like 1/2 and not 5/3) is always less than one
by definition, a fraction means a 'part of' so if you multiply a fraction of a fraction it is like finding a part of a part and if the origonal part was less than one, then the result will be less than one like

1/2 of 2/4= (2/4=1/4+1/4) so 1/2 of 2/4=1/4 which is less than one
