Answer:
The inequality 15m + 120 ≥ 200 represents the situation.
Step-by-step explanation:
Given that:
Diego started savings account with $120.
Amount deposited each month = $15
Number of months = m
The least balance he wants to have = $200
Amount deposited each month * No. of months + Amount deposited at start ≥ Least amount of balance
15*m + 120 ≥ 200
15m + 120 ≥ 200
Hence,
The inequality 15m + 120 ≥ 200 represents the situation.
Answer:
19 days
Step-by-step explanation:
1 - Make an equation with the variables provided.
150 + 200 + 12.50x = 587.50
2 - Simplify both sides.
350 + 12.50x = 587.50
3 - Subtract 350 from both sides.
12.50x = 237.50
4 - Divide by 12.50 to find your x variable.
x = 19 days

D(t) = -4t^3 + 40t^2 + 500t = 4088
4t^3 - 40t^2 - 500t + 4088 = 0
t = 7
Therefore, the plane has flown 4088 km 7 hours after it took off.
Answer:
21
Step-by-step explanation:
To find the mean, add up all the numbers
15+15+25+29 =84
Divide by the number of numbers
84/4 = 21
