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
8,915.632 in expanded form is:
8,000 + 900 + 10 + 5 + 0.6 + 0.03 + 0.002
Hope this helps
Brainliest always appreciated
Give me a thanks ❤
Very nice handwriting but the math and English are confusing.
Let's assume we're told
The subscript is important.
I think we're told the similar sum with 11 gives the smallest possible value for the sum. This is a rather cagey way of telling us 11 is the mean of the nine points. The mean is the number which minimizes the sum of squared deviations.
If 11 is the mean, the sum of the points is 9(11)=99.
Answer: 1080
Answer:
40
Step-by-step explanation:
A rain barrel is 65$ full
There are 26 gallons of water in the barrel
Therefore the numberr of gallons of water the barrel will hold can be calculated as follows
= 26×100/65
= 2600/65
= 40
Hence the barrel will hold 40 gallons of water
