Answer:
Principal = $4,500
Rate of interest=3%
Time = x years
We have to find number of years such that
Amount ≤$7020
Amount ≤ Principal + Simple interest
7020≤4500+ S.I
S.I≥7020-4500
S.I≥$2520
Formula for simple interest
S.I=
, where P=Principal, R=Rate of interest, T=time
2520≥
x≤
So, the solution set is (0,]
Answer: 5.6g - 2h + 9
Explanation:
Flip the sign of each term inside the parenthesis.
- The -5.6g becomes +5.6g or simply 5.6g
- The +2h becomes -2h
- The -9 becomes +9
These sign flips occur because of the negative out front the parenthesis. It's the same as having -1 outside, and we distribute the -1 through.
58,000 - 2,000 = 56,000
0.038(56,000) = $ 2128 <==
Answer:
probability the student plays both instruments is [ 
]
<h2>
<u>
Explanation</u>
:</h2>
students who play both instruments = total students - flute players - piano players - students who play neither instruments
students who play both instruments
→ 31 - 4 - 14 - 7
→ 6 students play both instruments.
probability:
