The answer is B) 30
parenthesis first (5×-3)(-2)
5×-3= -15
-15×-2= 30
Answer:
Answer explained below
Step-by-step explanation:
Let a be the working hours of plant A.
Let b be the working hours of plant H.
Let c be the working hours of plant M.
We have to minimize , Z = 60a + 92b + 140c
subject to constraint , 40a + 20b + 40c >=350
20a + 40b + 40c >=240
where a>=0 , b>=0 ,c>=0
So ,by solving this , a = 7.67 , b= 2.17 , c = 0
So ,working hours of plant A = 8 hrs
working hours of plant H = 3 hrs
working hours of plant M = 0 hrs
Answer:
About 90%
Step-by-step explanation:
If the cup was filled at a constant rate, then the cup fills at 70/2=35 cubic centimeters per second. The formula for the volume of a cone is , or in this case cubic centimeters. After 3 seconds, the cup would have 35*3=105 cubic centimeters of water inside of it, or about 89.52% which rounds to 90%. Hope this helps!
Answer:
b. f(x) = -2x +2
Step-by-step explanation:
The graph has a negative slope (m < 0) and a positive y-intercept (b > 0). The only equation with those characteristics is ...
f(x) = -2x +2
_____
<em>Additional comment</em>
The line on the graph appears to fall by 2 grid squares for each 3 to the right. That means it has a slope of ...
m = rise/run = -2/3
None of the offered equations have that slope. We have to assume the graph is "not to scale". Hence we can only comment on the signs of slope and intercept, and not their values.
