Answer:
1988920000000000
Step-by-step explanation:
1.98892 x 1000000000000000 (15 zeros)
The upper number (in this case 15) indicates the amount of zeros after the 1 (10 is 10^1, 100 is 10^2)
Answer:
In traffic, she drove for 3 hours
and After the traffic cleared she drove for 2 hours.
Explanation:
Given that the road trip was 136 miles;

The first part of the trip there was lots of traffic, she only averaged 16 mph;

The second part of the trip there was no traffic so she could drive 44 mph;

She traveled for a total of 5 hours;

let x represent the time in traffic when she traveled at 16 mph

the time the traffic is clear would be;

Recall that distance equals speed multiply by time;

substituting the values;

solving for x;

So;

Therefore, In traffic, she drove for 3 hours
and After the traffic cleared she drove for 2 hours.
The domain is about how far left-to-right the graph goes.
In relation to the x-axis, the graph starts at x = –3 (with an open circle at –3) and then continues over to the right forever.
This is the shown in the picture with the red markup.
In interval notation, this is (-3, infinity).
Remember to use that left-to-right orientation for interval notation!
The range is in turn about how low to how high the graph goes.
On the graph, I’d do the same thing I did on the red marked up graph and compare the graph to the y-axis.
The graph starts down at y = –5 (with an open circle at –5) and then continues on up forever.
In interval notation, this is (-5, infinity).
Answer:
D
Step-by-step explanation:
If we isolate the variable in each given compound inequality, we can quickly realize that D is correct.

x is less than or equal to four (solid point on 4 with line going left), but greater than -1 (open point going right).
Signs with 'or equal to' have solid points, and signs without are not solid.
I hope this helps!
Answer:
64
Step-by-step explanation:
16/100 = x / 400
Cross multiply:-
100x = 16*400
x = 6400 / 100
= 64
