Mathematics
1 answer:
PilotLPTM [1.2K]3 years ago
3 0

Answer:

a= 17√3/ 2 or a≈14.72

Step-by-step explanation:

c = 17 and is the side opposite to the angle C

c=AB =17

a= BC because is the side opposite to angle A

sin 60° = opp./hyp = BC / AB = BC/17

sin 60° = BC /17  multiply both sides by 17

BC = 17* sin 60 = 17√3/2 ≈14.72

Sylvia has 51.78 pounds of dirt. She has 20 buckets and would like to put 2.56 pounds of dirt into each bucket. Are there enough
antoniya [11.8K]

Answer:

There isn't enough buckets for all of the dirt to be in a bucket.

Step-by-step explanation:

From the question,

She has 20 buckets and would like to put 2.56 pounds of dirt into each bucket.

Hence, the total number of dirt that can be in the 20 buckets is

20 × 2.56

= 51.20 pounds of dirt

Slyvia has 51.76 pounds of dirt.

51.76 - 51.20

= 0.56 pounds of dirt.

From the above calculation we can say that there isn't enough buckets for all of the dirt to be in a bucket
