Answer:
110,000
Step-by-step explanation:
since it covered 11,000 square miles at a rate of 0.10 miles per hour
11,000 /0.10=110000
Answer:
B. Y²⁴
Step-by-step explanation:
For perfect cubes, the exponents are a multiple of three. If yᵃ is a perfect cube, then a/3=k where k is a whole number.
Among the provided choices, the exponent of y²⁴ is divisible by 3.
24/3 = 8.
Thus y²⁴ is a perfect cube.
Revenue: 2x² + 17x - 175
Cost: 2x² - 3x - 125
Profit: 20x - 50
Profit = Revenue - Cost
Profit = 2x² + 17x - 175 - (2x² - 3x - 125)
Profit = 2x² - 2x² + 17x + 3x - 175 + 125
Profit = 20x - 50
x = 75
profit = 20(75) - 50
profit = 1500 - 50
profit = 1450
3000, round up since 722 is closer to 1000 than to 0
Answer:
For a scientific experiment, a physicist must make sure that the temperature of metal at 0° C gets no colder than -80° C. The physicist changes the metal’s temperature at a steady rate of -4° C per hour. For how long can the physicists change the temperature?
