Using the given formula speed = distance over time:
Speed = 70 miles / 3 hours
Speed = 23.33 miles per hour
Convert miles per hour to meters per hour:
1 mile = 1609 meters:
23.33 miles x 1690 meters = 37,543.33 meters per hour.
Now convert meters per hour to meters per second:
1 hour = 3600 seconds:
37,543.33 / 3600 = 10.4 meters per second.
Answer:
8.06
Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
We require 2 equations with the recurring decimal placed after the decimal point.
let x = 0.7272.... (1) ← multiply both sides by 100
100x = 72.7272... (2)
Subtract (1) from (2) thus eliminating the recurring decimal
99x = 72 ( divide both sides by 99 )
x = 
= 
Answer:
1 over 4
Step-by-step explanation:
Answer:
[(x+5)²+(y+3)²]
Step-by-step explanation:
- length = 5 units and width = 3 units
- x is for length as y is for width
- (x+5) for length & (y+3) for width
- [(x+5)²+(y+3)²]
