Answer:
50.465 km
Step-by-step explanation:
In order to find the distance in kilometers, you need to first convert the marathon distance into yards. Since the conversion measurement of 1 mile = 1760 yards is given, you can use this to find the total yards in 26 miles:
or x = 45,760 yards
Adding this amount to the additional 385 in the marathon distance:
45760 + 385 = 46,145 yards
Since 1 yard = 0.9144 meters, we can find the number of meters the same way we found yards:
or m=50,465 meters
Since the question is asking for kilometers, we can need to divide the number of meters by 1000, or move the decimal point three places to the left:
50,465 ÷ 1000 = 50.465 km
For this, all you need is the velocity formula which is Vf = Vi + at.
Vf = final velocity.
Vi = initial velocity.
a = acceleration
t = time
Vf = Vi + at.
Vf= 0 + (-<span> 9.8 m/sec^</span><span>2) (7s)
</span>
*The 0 says that the original velocity is zero. The - 9.8 m/sec^2 is gravity because there is nothing else acting upon it, and it is negative because it is falling. The 7s is time time.*
All you have to do then, is simplify to get 68.6 m/s which is B.

Answer:
X=2y-6
Step-by-step explanation:
Y = 1/2 X+3
Y = X/2+3
Y = X+2•3/2
Y = X+6/2
2y = X+6
2y + (-6) = (X+6) + (-6)
2y-6 = X+6-6
2y-6 = X
Answer: X = 2y-6 I hope it helps....
Answer:
X = 9.2
Step-by-step explanation:
You have to use the pythagorean theorm, which is a squared + b squared = c squared. Looking at the triangle, the vertical line is 6, and the horizontal is 7.
6squared + 7squared = c squared
85 = csquared
Take the square root of both sides to get rid of the squared on the c.
sqroot of 85 = 9.2
