Answer:
1,100 ounces because 20 × 30 + 10 × 50 = 1,100
Step-by-step explanation:
Answer:
(2, -3)
Step-by-step explanation:
Compare the given (x-2)2+(y+3)2=9 to the standard equation
(x - h)^2 + (y - k)^2 = r^2.
It becomes obvious that h = 2, k = -3 and r = 3.
The center of this circle is (h, k): (2, -3).
Answer:
D.
Step-by-step explanation:
In order for it to be the solution, it must be less than or equal to -2. D (-1.76) is bigger than -2, which means it is not a part of the solution.
Answer:
1.47 times 10 to the power of -3
Step-by-step explanation:
8th grade math I'm guessing lol
Their distance differs by 15 miles for each hour of travel time. Thus, the travel time of interest is
.. (180 -144) miles/(15 miles/hour) = 2.4 hour
The red car's speed is 180 mi/(2.4 h) = 75 mi/h.
The blue car's speed is 144 mi/(2.4 h) = 60 mi/h.
