Answer:
The total amount is 384
Step-by-step explanation:
Let m = the amount of money
5/8 of the money is 240
5/8 * m = 240
Multiply each side by 8/5
8/5 * 5/8 * m = 8/5 * 240
m =384
The total amount is 384
54 = 3x + 37.5 <== ur equation....and x = number of years
54 - 37.5 = 3x
16.5 = 3x
16.5 / 3 = x
5.5 = x......so it would take 5.5 years...or 5 1/2 years <=
Answer:
<em>The wind speed was 31 miles per hour when the experiment began.</em>
Step-by-step explanation:
<u>Linear Dependency</u>
The wind speed is known to increase at a rate of 3 miles per hour every hour.
From 9:00 a.m. to 4:00 p.m. there are 7 hours.
Thus, the speed increased by 7 * 3 = 21 miles per hour during that period of time.
Assuming the wind increased linearly, and its speed was measured at 52 miles per hour at 4:00 p.m., then the initial speed at 9:00 a.m. is calculated by subtracting:
52 miles / hour - 21 miles / hour = 31 miles / hour
The wind speed was 31 miles per hour when the experiment began.
Answer:
25%
Step-by-step explanation:
Convert days into hours
3 days = 3×24 = 72 hours
18/72 × 100 = 25%
