Answer:
6.5 miles in 1 hour and they will run 75% of the full distance in 1 hour.
Step-by-step explanation:
The distance covered by two marathon runners = 26 miles
They takes 4 hours
We need to find how many miles did they run in 1 hour
In 4 hour, the distance covered is 26 miles
To find distance covered in 1 hour, divide 26 by 4 such that.
So, they will cover 6.5 miles in 1 hour.
For percentage,
So, they will run 75% of the full distance in 1 hour.
Answer:
n=-4
Step-by-step explanation:
n/2+5=3
n/2=-2
n=-4
Answer:
3
Step-by-step explanation:
15-2x=9
or,-2x=9-15
or, x=-6/-2
x=3
For this case we have the following equation:
sin (40o) = b / 20
Clearing b we have:
20 * sin (40o) = b
Therefore, the length of the AC segment is given by:
b = 12.9
Answer:
the length of AC is:
b = 12.9
Step-by-step explanation:
Given
Slope (m) = 4
Point ( -1 , 5)
Now the equation of line is
y - y1 = m ( x - x1)
y - 5 = 4 ( x + 1)
y - 5 = 4x + 4
4x + 4 - y + 5= 0
4x - y + 9 = 0
which is the required equation
