A road crew must repave a road that is 3/5 miles long. They can repave 1/15 miles each hour. How long will it take the crew to repave the road?

Answers

The Total number of hours required to repave the whole road is 36.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

The Total length of the road that needs to be repaved =  3/5 miles

The Total length of the road which is repaved by the road crew per hour = 3/5  miles

The Total number of hours required to repave the whole road

= (Length of the road  to be repaved)/(Length of the road repaved by the crew per hour)

= 3/4 divided by 1/48

= 3/4*48/1= 144/4

= 36

Hence, The Total number of hours required to repave the whole road is 36.

None of the other answers are correct

Answers

Answer: (0,0),(0,4), and (5,0)

Step-by-step explanation:

It is easy to find lengths of horizontal and vertical segments and distances from (0,0) so always place one vertex at the origin and one or more sides on an axis.

This answer has an x intercept and y intercept.

For 1st. 
you can solve it by general law or , 
since the coefficient of r^2 = 1 
so u should think of 2 number which if u multiple them gives you 27 and sum of them is 12 and those numbers are 9 , 3 
so the answer (x+9)*(x+3) 
2nd problem :
g^2 - 9 = (g-3)*(g+3) 
3rd problem:
2p^3 + 6p^2 + 3p +9 
1st divide it into two parts 
(2p^3 +6p^2)+    (3p+9)
from the 1st part 
take 2p^2 as a common factor and from part 2 take 3 as a common factor and the equation be like 
2p^2(p+3)  + 3(p+3)
then take (p+3) as a common factor
so (p+3)* ( 2p^2 +3 )                                                         
1: (r+3)(r+9). 2: (g+3)(g-2). 3: (2p^2+3)(p+3). FOIL multiply the first, inside, outside, and last terms. add the inside and outside terms together. :)
