Answer:
310
Step-by-step explanation:
The maximum possible number is obtained when each family owns one appliance only. That total is ...
60 + 85 +70 +95 = 310
The maximum possible number of families is 310.
Answer:
Accelerating to top speed, deaccelerating to finish line.
Step-by-step explanation:
If the runner kept a constant speed of 11 mph for the whole duration of his run (32 minutes), the distance he would have covered is:
This means that, in order to run the full 6.2 miles, the runner needs to reach a speed over 11 mph. Assume he starts from rest, while accelerating the runner reaches, and the surpasses, the 11 mph mark. Since his speed at the finish line is zero, the runner has to deaccelerate from his current running speed (which should be higher than 11 mph), passing through 11 mph and reaching zero at the finish line.
Answer:
B
Step-by-step explanation:
look at the graph, it is really easy with such basic numbers involved :
the red dotted line is
y = 2
since the line is dotted (= the points on the line are not included in the solution), the colored area is below the line is
y < 2
the blue line is clearly just a 45° basic line through the origin (0,0), and that means for every point in that line x is equal to y.
y = x
and the line is solid, so the points are included in the solution. the shaded area is above the line, so, we need to use the ">" relation :
y >= x
the required solution is the combination of both, and therefore, B is correct.
Answer:
X= 5 ( 2 + Y )❤️
Step-by-step explanation:
- X = 5y + 10
- 2x-10y= 20
- 2( X - 5y ) = 20
- (x-5y ) = 20/2
- X - 5y = 10
- X= 10 + 5y
- X = 5 ( 2 + Y )
