Answer:
v = 23.370 mph
Step-by-step explanation:
It is given that,
The world record for the 100 meter dash is finished in 9.572 seconds in Berlin. We need to find the Bolt’s average race speed in miles per hour.
We know that,
1 mile = 1.609 km
or
1 mile = 1609.34 m
⇒ 100 m = 0.0621 miles
1 hour = 3600 seconds
⇒ 1 second = (1/3600) hour
Average speed = distance/time
So,
or
v = 23.370 mph
Hence, Bolt’s average race speed is 23.370 mph.
Answer:
justin = 135 & greg = 150
Step-by-step explanation:
equations:
(justin is 15lbs under greg) j-15=g
(find gregs full weight by doubling bc the problem gave you half) 75*2=150
(plug in gregs wieght to find justins weight) j-15=150 -> j=135
Answer:
There is no solution (since none has side length of 4 units)
Step-by-step explanation:
If V (-1,1) is one of vertex of a square, then the next vertex to V distance must be the known value of 4
VA: V to (-3,3) = √(-1 - -3)² + (1 - 3)² = √8 = 2.8
VB: to (-5,-3) = √(-1 - -5)² + (1 - -3)² = √32 = 5.7
VC: o (3,3) = √(-1 -3)² + (1 - 3)² = √20 = 4.47
VD: to (-5,3) = √(-1 - -5)² + (1 - 3)² = √20 = 4.47
VE: to (4,5) = √(-1 - 4)² + (1 - 5)² = √41 = 6.4
