answer: 4.75
Step-by-step explanation:
To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points. Which means, y1 - y2 / x1 - x2 = 29 - (-9) / 15 - 7
= 29 + 9 / 8
= 38/8
=4.75
It would mean the fence has to be 41 feet long and 36 feet wide. To find the perimeter of the fence, it would be 41+41+36+36 which equals 82+72 so 154 feet of fencing
Answer:
1107 feets below sea level
Step-by-step explanation:
Given that :
Initial elevation of submarine = 984.6 feets below sea level
Depth of dive from initial elevation = 122.4 feets below sea level
The elevation after the dive :
Initial elevation + depth of dive
984.6 + 122.4
= 1107 feets below sea level
Answer:
Step-by-step explanation:
b and c are the speeds of the boat and current, respectively.
Traveling upstream, the boat moves b-c km per hour.
Traveling downstream, the boat moves b+c km per hour.
b-c = (60 km)/(½ h) = (120 km)/h
b+c = (60 km)/(⅓ h) = (180 km)/h
Adding the equations together,
2b = (300 km)/h
b = (150 km)/h
c = (30 km)/h
Answer:
<em> </em>
Step-by-step explanation:
Since 
is below 
, you would move the decimal right 
times.
That will get you to .
Since we moved it right two times, we get a number in between
