The initial height of the balloon is 10 feet which then increases by 70% to (10 ×1.7) = 17 feet, then to (17 × 1.7) =28.9 feet, and so fourth if the rate of increase is kept constant. Therefore, forming a geometric sequence such that to get any term in the sequence we use the formula ar∧(n-1), where a is the first term, r is the common ratio, and n is the term in the sequence. In this case a is 10 and r= 1.7 , to get the height in the fourth minute it means n =5 (for the first term there is 0 minutes, such that for 0 minutes n= 1)
Thus, 10 × 1.7 ∧ 4 = 83.521 feet.
Therefore, the answer is 83.521 feet
Proportional numbers are numbers with the same equivalent ratio
98/126 is proportional to 84/108
The number is given as:
Reduce fraction to the lowest term
Reduce 86/110 to the lowest term
Divide by 2/2
43/55 is not equivalent to 7/9
Reduce 98/126 to the lowest term
Divide by 14/14
7/9 is equivalent to 7/9.
Hence, 98/126 is proportional to 84/108

Answer:
The answer is 6z-28
Step-by-step explanation:
20 - 3[4(z+1) - 6(z-2)]
= 20 - 3(4z+4-6z+12)
= 20 - 3(16 - 2z)
= 20 - 48 + 6z
= 6z - 28
1 is 4/5=8/10=16/20
2 is 9/2=18/4=3616
3 is 11/12=22/24= 44/48
4 is 6/10=12/20=24/40
5 is 8/6=16/12=32/24
6 is 3/7=6/14=12/142
