It takes 7 hours for 12 men to paint a room.

how many men would be needed to paint the room in 3 hours?

28 men would be required to paint the room

Step-by-step explanation:

if every man work independently of the others in the room ( that means that each one works in parallel without interrupting the others).

time required to paint = time that each men worked * number of man that worked in the room = 7 hours/ men * 12 men = 84 hours

since the time required to paint the room is 84 hours, if we have need to finish in 3 hours, the number of men that should be working are

time required to paint = time that each men worked * number of man that worked in the room

or

number of man that worked in the room = time required to paint / time that each men worked = 84 hours / 3 hours/men = 28 men

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
