Answer:
300 seconds = 5 minutes
Step-by-step explanation:
At first convert the time in minutes which is
5.75 * 60 = 345 seconds
No as the average is 345 seconds at starts from 45 so we subtract that time from 45 seconds
345-45 = 300 seconds (Mean)
So 300 seconds = 300/60 = 5 minutes
So the Accurate mean is 5 minutes
Answer:
y = 1/2x - 1
Step-by-step explanation:
When you put all three equations from the question into a graph and then input the equation i just gave you it will be perpendicular to line B & C, also it will be parallel to line A. Finally you can check yourself that it also has a y-intercept of (0,-1) & an x-intercept of (2,0). Hopefully this helps out & gets brainliest. xD
Answer:
75cm
Step-by-step explanation:
Well, I can't see a photo, so I'll have to assume that the description provides enough info.
10cm/2km = x/15km,
where x is the distance on the map (in centimeters) of a real-life distance of 15 kilometers.
10cm/2km = x/15km
10/2 = 5/1
This means we have to multiply 5 by 15 to find x.
x = 5 · 15
x = 75
Let's plug the new value back in...
10cm/2km = x/15km
10cm/2km = (75cm)/15km
<em>(Simplify each side to its simplest form)</em>
10cm/2km = 75cm/15km
5/1 = 5/1
It works! So x = 75cm.
Hope this helps! :)
