This is Very good correct
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
Answer:(125-81.25)/125 = 0.35 = 35%
Step-by-step explanation:
Answer:
x > -7
Step-by-step explanation:
20 + 8 > -4x
Simplify
28 > -4x
Divide both sides by 4
-28/4 < x
-7 < x
x > -7
Answer:
Step-by-step explanation:
<u>Given</u>
- Daily charge = $68.80
- Charge per mile = $0.08
- Target distance = 325 miles
- Money limit = $370
<u>Required inequality:</u>
<u>Solving for d:</u>
- 68.8d + 26 ≤ 370
- 68.8d ≤ 344
- d ≤ 344/68.8
- d ≤ 5
Up to 5 days is the answer
