Aconstruction crew has just finished building a road. the crew worked for 14.4 days. if they built 3.5 kilometers of road each day, find the total length of road they built

50.4 kilometer

Step-by-step explanation:

Given: A construction crew has just finished building a road. The crew worked for 14.4 days. If they built 3.5 kilometers of road each day.

To Find: the total length of road they built.

Solution:

The number of days construction crew worked

kilometers of road built by construction everyday

Now,

Total length of road built by construction road by crew

On putting values,

Therefore, Total length of road built by construction crew in is          

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
