The first thing you would want to do is to draw it out. Once you've drawn it out, you want to add the "imaginary lines" so the trapezoid will form into a rectangle. Then find out the area which is L * W. The area for the rectangle is 20.

Finally you want to take those imaginary pieces and find the area of those. Which would be three and then you want multiply by two since there is two of them. The last thing you need to do is subtract the six from 20.

<u>Therefore the answer is 12.</u>

Calculate time period of a simple pendulum if it takes 72 seconds to complete 24 oscillations

Anvisha [2.4K]

Answer:

The time period of a simple pendulum if it takes 72 seconds to complete 24 oscillation will be 3 seconds.

Step-by-step explanation:

Total number of oscillations = 24

Time taken to complete 24 oscillations = 2 seconds

So, the frequency 'f' of the simple pendulum will be:

$f=\frac{24}{72}$

$f=\frac{1}{3}$

Let 'T' be the time period.

$T=\frac{1}{f}$

$T=\frac{1}{\frac{1}{3}}$

$\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{1}{\frac{b}{c}}=\frac{c}{b}$

$T=\frac{3}{1}$

$T=3$

Therefore, the time period of a simple pendulum if it takes 72 seconds to complete 24 oscillation will be 3 seconds.

56 thousandths - 23 thousandths=how many hundredths and thousandths?

alexandr1967 [171]

<span>56 thousandths - 23 thousandths=how many hundredths and thousandths?
Let us first solve this and get the difference of the given numbers.
=> 56 thousandths = 0.056 (there are 5 hundredths and 6 thousandths)
=> 23 thousandths = 0.023 (there are 2 hundredths and 3 thousandths)
=> 0.056 – 0.023 = 0.033 is the answer
there 3 hundredths and 3 thousandths value left after subtracting the given 2 decimal numbers.</span>
