Aroad crew must repave a road that is 4/5 miles long. they can repave 1/20 miles each hour. how long will it take the crew to repave the road

16 hours

Step-by-step explanation:

Total length of the road that needs to be repaved = miles

Total length of the road which is repaved by the road crew per hour = miles

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)

=

=

= 16 hours

14

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
