Answer:
Step-by-step explanation:
Sam bought a chocolate. He ate some and leaving 0.75 for Alice.
Alice ate 18.50 grams of chocolate and return the rest to Sam, which was 65% of the original chocolate. How much chocolate did Sam had at the beginning?
Now solve the equation:
0.75x - 18.50 = 0.65x
Combine the like terms:
0.75-0.65x = 18.50
0.1x= 18.50
x = 18.50/0.1
x=185
This shows that Sam had 185 grams of chocolate...
It would be the second anser: 15m+2n
Question:
What is the area of the sector? Either enter an exact answer in terms of π or use 3.14 and enter your answer as a decimal rounded to the nearest hundredth.
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete as the values of radius and central angle are not given.
However, I'll answer the question using the attached figure.
From the attached figure, the radius is 3 unit and the central angle is 120 degrees
The area of a sector is calculated as thus;

Where
represents the central angle and r represents the radius
By substituting
and r = 3
becomes



square units
Solving further to leave answer as a decimal; we have to substitute 3.14 for 
So,
becomes

square units
Hence, the area of the sector in the attached figure is
or 9.42 square units
