X is equal to 8. The work for that is on the attached picture.
The simplified answer is 0.23
The answer is-. 63
.0= tenths
.00= hundredths
how to round:
ex. let's say the number is 51 and it says to round to the nearest tens place you look at the new mber before it to round. So you would loom at the 1, keep in mind that any number lower than 5 toy round down. so the answer would be 50. Now consider the number 57 you would round up because 5 or greater you would round up so it would be 60.
Answer:
732.21 m
Step-by-step explanation:
Given the time taken by cadet to cross an obstacle and swing back to where he started = 5.5 seconds
The formula for a complete oscillation(to and fro) period is
<h2>T = 2π * √(L/g)</h2>
where:
<em>T is the period of oscillations</em><em> - time that it takes for the pendulum to complete one full back-and-forth movement.</em>
<em />
<em>L is the length of the pendulum </em>
<em />
<em>g is the acceleration of gravity, which</em><em> is equal to 9.81 m/s^2 </em>
5.5 = 2 π √(L / 9.81)
5.5/2π = √(L / 9.81)
8.64 = √L / 9.81
8.64 ² = L / 9.81
74.64 = L / 9.81
L = 74.64 * 9.81
L = 732.21 m
