Answer: T= 3.54
Step-by-step explanation:
Step 1
Given that
The time period, T, s doirectly proportional to the square root of the length, d, of the pendulum, we have that
T ∝ 
Introducing the constant of proportionality, we have that
T= K.
Step 2
When d=6, T=5, K =?
T= K.
5 = k
5= k x 2.44949
k =5/2.44949
k =2.041
Therefore, when d = 3 , T= ?
T= K
T= 2.041 x 
T= 3.53511≈ 3.54
Step-by-step explanation:
Number of sides of the given polygon, n =5
Sum of interior angles =( n-2)180°
=( 5 - 2)180°
= 3*180°
= 540°
Missing angle, x = 540°- (100°+105°+110°+145°)
= 540°- 460°
= 80°
Answer:
22 days = 3 weeks and 1 day
454 minutes = 7 hours and 34 minutes
4 years and 4 months = 148 months
12 pounds and 13 ounces = 205 ounces
Answer:
$21
Step-by-step explanation:
-- To change a percent into a decimal, move
the decimal point two places this way <== .
33.3% = 0.333 .
-- To change a percent into a fraction, remember
that the symbol ' % ' means ' /100 ' .
33.3 % = 33.3/100 .
That fraction looks ugly, because it has a decimal in the numerator.
That's easy to fix. Multiply top and bottom by 10, and you have
333/1000 .
