Acarpenter can install 8 sheets of drywall in 10 minutes. at this rate, how long does it take to install one sheet of drywall? how long will it take the carpenter to install 60 sheets?

a) 1.25 minutes; 1.25 hours
eliminate
b) 1.5 minutes; 1.5 hours
c) 2 minutes; 2 hours
d) 2.5 minutes; 2.5 hours

Answer

Find out the  how long does it take to install one sheet of drywall .

To prove

As given

A carpenter can install 8 sheets of drywall in 10 minutes.

8 sheets = 10 mintues

Now

Time taken for installing one sheets of drywall = 1.25 mintues.

Now Find out how long will it take the carpenter to install 60 sheets .

To prove

As given

A carpenter can install 8 sheets of drywall in 10 minutes.

8 sheets = 10 mintues

Now for 60 sheets.

As 1 hour = 60 mintues

Now convert 75 mintues into the hours.

 Time taken for installing 60 sheets = 1.25 hours.

Therefore the option (A) is correct.

Thus 1.25 minutes take to install one sheet of drywall and 1.25 hours take the carpenter to install 60 sheets .

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218
