Answer:
50 gallons per hour
Step-by-step explanation:
400/8 = 50
Since the plane descends 1,300 feet per minute it would descend 19,500 feet after 15 minutes (1,300 x 15 = 19,500) Subtract this from the plane's initial altitude 32,000 and the new altitude will be 12,500. (32,000-19,500=12,500)
Answer:
- Friday's tickets: $26 each
- Saturday's tickets: $35 each
Step-by-step explanation:
We presume that 4 tickets were bought each day, so the price of 1 ticket is 1/4 of the total price:
(1/4)($104) = $26
(1/4)($140) = $35
The cost of each ticket on Friday was $26; on Saturday, the cost was $35.
Answer:
Part A is 34
Part B is 2
Step-by-step explanation:
This question did provide some clues to answer this question. Every week, the area covered by the algae is multiplied by 2^1.
To find the area cover increase by the algae per day, the exponent should be divided by 7 since there are 7 days in a week. Hence, every day, the area covered by the algae multiplies by 2^(1/7). In other words, 1 day after the algae was spotted, the area is 12.5 * 2^(1/7), which answers part B.
10 days after the algae was spotted, the area covered by the algae is 12.5 * 2^[(1/7)*10] = 33.6475... , which rounds up to 34 and answers part A.
