(71+x)/2=78
71+x=156
x=85
Th student needs to score a min of 85
∠P=∠R, ∠Q=2∠R
the three angles make a total of 180, so
∠P+∠R+∠Q=180
∠R+∠R+2∠R=180
∠R=45
∠P=45, ∠Q=90
Answer:
Skills are the talent or the expertise that one possesses to do a certain type of a job.
Step-by-step explanation:
Technology may be defined as the summation of skills, methods, techniques and processes that are used for the goods production as well as the services. Technology also helps in accomplishing certain objectives, such as scientific investigation.
People can improve their skill sets and knowledge though technology.
For improving the conversion skills in conversions by the use of technology, we can :
1. We can use different scientific methods to do the conversion more quickly.
2. We can use the computer technology to do the conversion so that we get an accurate result and more reliable result.
3. We can develop mobile applications where people just can insert in the data and get the conversion immediately.
Start by defining your variables
let x be the mass of a single mango in gm
let y be the mass of a single orange in gm
now, write the question as a system of equations
3 mango and 2 orange have a mass of 200 gm
3x +2y = 200
4 mango and 4 orange have a mass of 300 gm
4x +4y = 300
now you have a system of equations
3x+2y =200
4x+4y =300
solve for x and y
